Data Manipulation Language (DML)
This section describes the migration syntax of MySQL DML. The migration syntax determines how the keywords and features are migrated.
For details, see the following topics:
INSERT
In MySQL, INSERT allows the following keywords: HIGH_PRIORITY, LOW_PRIORITY, PARTITION, DELAYED, IGNORE, VALUES, and ON DUPLICATE KEY UPDATE. GaussDB(DWS) does not support these keywords, and DSC will convert them.
- HIGH_PRIORITY
MySQL uses HIGH_PRIORITY will override the effect of the LOW_PRIORITY option.
Input
# HIGH_PRIORITY INSERT HIGH_PRIORITY INTO exmp_tb2 VALUES(100, 12.3, 'cheap', '2018-11-11'); INSERT HIGH_PRIORITY INTO exmp_tb2 VALUES(DEFAULT, 128.23, 'nice', '2018-10-11'); INSERT HIGH_PRIORITY INTO exmp_tb2 VALUES(DEFAULT, DEFAULT, 'nice', '2018-12-14'); INSERT HIGH_PRIORITY INTO exmp_tb2 VALUES(DEFAULT, DEFAULT, 'nice', DEFAULT); INSERT HIGH_PRIORITY INTO exmp_tb2 (tb2_id, tb2_price) VALUES(DEFAULT, DEFAULT); INSERT HIGH_PRIORITY INTO exmp_tb2 (tb2_id, tb2_price, tb2_note) VALUES(DEFAULT, DEFAULT, DEFAULT); INSERT HIGH_PRIORITY INTO exmp_tb2 (tb2_id, tb2_price , tb2_note) VALUES(DEFAULT, DEFAULT, DEFAULT); INSERT HIGH_PRIORITY INTO exmp_tb2 (tb2_id, tb2_price, tb2_note, tb2_date) VALUES(DEFAULT, DEFAULT, DEFAULT, DEFAULT);
Output
-- HIGH_PRIORITY INSERT INTO "public"."exmp_tb2" VALUES (100,12.3,'cheap','2018-11-11'); INSERT INTO "public"."exmp_tb2" VALUES (DEFAULT,128.23,'nice','2018-10-11'); INSERT INTO "public"."exmp_tb2" VALUES (DEFAULT,DEFAULT,'nice','2018-12-14'); INSERT INTO "public"."exmp_tb2" VALUES (DEFAULT,DEFAULT,'nice',DEFAULT); INSERT INTO "public"."exmp_tb2" ("tb2_id","tb2_price") VALUES (DEFAULT,DEFAULT); INSERT INTO "public"."exmp_tb2" ("tb2_id","tb2_price","tb2_note") VALUES (DEFAULT,DEFAULT,DEFAULT); INSERT INTO "public"."exmp_tb2" ("tb2_id","tb2_price","tb2_note") VALUES (DEFAULT,DEFAULT,DEFAULT); INSERT INTO "public"."exmp_tb2" ("tb2_id","tb2_price","tb2_note","tb2_date") VALUES (DEFAULT,DEFAULT,DEFAULT,DEFAULT);
- LOW_PRIORITY
When the LOW_PRIORITY modifier is used, execution of INSERT is delayed.
Input
# LOW_PRIORITY INSERT LOW_PRIORITY INTO exmp_tb2 VALUES( DEFAULT, '128.23', 'nice', '2018-10-11'); INSERT LOW_PRIORITY INTO exmp_tb2 VALUES(DEFAULT, DEFAULT, 'nice', '2018-12-14' ); INSERT LOW_PRIORITY INTO exmp_tb2 VALUES(DEFAULT, DEFAULT, 'nice', DEFAULT); INSERT LOW_PRIORITY INTO exmp_tb2 (tb2_id, tb2_price) VALUES(DEFAULT, DEFAULT); INSERT LOW_PRIORITY INTO exmp_tb2 (tb2_id, tb2_price, tb2_note) VALUES(DEFAULT, DEFAULT, DEFAULT);
Output
-- LOW_PRIORITY INSERT INTO "public"."exmp_tb2" VALUES (DEFAULT,'128.23','nice','2018-10-11'); INSERT INTO "public"."exmp_tb2" VALUES (DEFAULT,DEFAULT,'nice','2018-12-14'); INSERT INTO "public"."exmp_tb2" VALUES (DEFAULT,DEFAULT,'nice',DEFAULT); INSERT INTO "public"."exmp_tb2" ("tb2_id","tb2_price") VALUES (DEFAULT,DEFAULT); INSERT INTO "public"."exmp_tb2" ("tb2_id","tb2_price","tb2_note") VALUES (DEFAULT,DEFAULT,DEFAULT);
- PRATITION
When inserting into a partitioned table, you can control which partitions and subpartitions accept new rows.
Input
INSERT INTO employees PARTITION(p3) VALUES (19, 'Frank1', 'Williams', 1, 2); INSERT INTO employees PARTITION(p0) VALUES (4, 'Frank1', 'Williams', 1, 2); INSERT INTO employees PARTITION(p1) VALUES (9, 'Frank1', 'Williams', 1, 2); INSERT INTO employees PARTITION(p2) VALUES (10, 'Frank1', 'Williams', 1, 2); INSERT INTO employees PARTITION(p2) VALUES (11, 'Frank1', 'Williams', 1, 2);
Output
INSERT INTO "public"."employees" VALUES (19,'Frank1','Williams',1,2); INSERT INTO "public"."employees" VALUES (4,'Frank1','Williams',1,2); INSERT INTO "public"."employees" VALUES (9,'Frank1','Williams',1,2); INSERT INTO "public"."employees" VALUES (10,'Frank1','Williams',1,2); INSERT INTO "public"."employees" VALUES (11,'Frank1','Williams',1,2);
- DELAYED
In MySQL 5.7, the DELAYED keyword is recognized but ignored by the server.
Input
# DELAYED INSERT DELAYED INTO exmp_tb2 VALUES(99, 15.68, 'good', '2018-11-12'); INSERT DELAYED INTO exmp_tb2 VALUES(80, 12.3, 'cheap', '2018-11-11'); INSERT DELAYED INTO exmp_tb2 VALUES(DEFAULT, 128.23, 'nice', '2018-10-11'); INSERT DELAYED INTO exmp_tb2 VALUES(DEFAULT, DEFAULT, 'nice', '2018-12-14'); INSERT DELAYED INTO exmp_tb2 VALUES(DEFAULT, DEFAULT, 'nice', DEFAULT); INSERT DELAYED INTO exmp_tb2 (tb2_id, tb2_price) VALUES(DEFAULT, DEFAULT); INSERT DELAYED INTO exmp_tb2 (tb2_id, tb2_price, tb2_note) VALUES(DEFAULT, DEFAULT, DEFAULT); INSERT DELAYED INTO exmp_tb2 (tb2_id, tb2_price, tb2_note, tb2_date) VALUES(DEFAULT, DEFAULT, DEFAULT, DEFAULT);
Output
-- DELAYED INSERT INTO "public"."exmp_tb2" VALUES (99,15.68,'good','2018-11-12'); INSERT INTO "public"."exmp_tb2" VALUES (80,12.3,'cheap','2018-11-11'); INSERT INTO "public"."exmp_tb2" VALUES (DEFAULT,128.23,'nice','2018-10-11'); INSERT INTO "public"."exmp_tb2" VALUES (DEFAULT,DEFAULT,'nice','2018-12-14'); INSERT INTO "public"."exmp_tb2" VALUES (DEFAULT,DEFAULT,'nice',DEFAULT); INSERT INTO "public"."exmp_tb2" ("tb2_id","tb2_price") VALUES (DEFAULT,DEFAULT); INSERT INTO "public"."exmp_tb2" ("tb2_id","tb2_price","tb2_note") VALUES (DEFAULT,DEFAULT,DEFAULT); INSERT INTO "public"."exmp_tb2" ("tb2_id","tb2_price","tb2_note","tb2_date") VALUES (DEFAULT,DEFAULT,DEFAULT,DEFAULT);
- IGNORE
When the IGNORE modifier is used, errors that occur during INSERT execution are ignored.
Input
# New data will be ignored if there is duplicate in the table. INSERT IGNORE INTO exmp_tb2 VALUES(189, '189.23','nice','2017-11-12'); INSERT IGNORE INTO exmp_tb2 VALUES(130,'189.23','nice','2017-11-12'); INSERT IGNORE INTO exmp_tb2 VALUES(120,15.68,'good','2018-11-12'); INSERT IGNORE INTO exmp_tb2 VALUES(DEFAULT,128.23,'nice','2018-10-11'); INSERT IGNORE INTO exmp_tb2 VALUES(DEFAULT,DEFAULT,'nice','2018-12-14'); INSERT IGNORE INTO exmp_tb2 VALUES(DEFAULT,DEFAULT,'nice',DEFAULT);test INSERT IGNORE INTO exmp_tb2 (tb2_id,tb2_price) VALUES(DEFAULT,DEFAULT); INSERT IGNORE INTO exmp_tb2 (tb2_id,tb2_price,tb2_note) VALUES(DEFAULT,DEFAULT,DEFAULT); INSERT IGNORE INTO exmp_tb2 (tb2_id,tb2_price,tb2_note,tb2_date) VALUES(DEFAULT,DEFAULT,DEFAULT,DEFAULT);
Output
-- New data will be ignored if there is duplicate in the table. INSERT INTO "public"."exmp_tb2" VALUES (101,'189.23','nice','2017-11-12'); INSERT INTO "public"."exmp_tb2" VALUES (130,'189.23','nice','2017-11-12'); INSERT INTO "public"."exmp_tb2" VALUES (120,15.68,'good','2018-11-12'); INSERT INTO "public"."exmp_tb2" VALUES (DEFAULT,128.23,'nice','2018-10-11'); INSERT INTO "public"."exmp_tb2" VALUES (DEFAULT,DEFAULT,'nice','2018-12-14'); INSERT INTO "public"."exmp_tb2" VALUES (DEFAULT,DEFAULT,'nice',DEFAULT); INSERT INTO "public"."exmp_tb2" ("tb2_id","tb2_price") VALUES (DEFAULT,DEFAULT); INSERT INTO "public"."exmp_tb2" ("tb2_id","tb2_price","tb2_note") VALUES (DEFAULT,DEFAULT,DEFAULT); INSERT INTO "public"."exmp_tb2" ("tb2_id","tb2_price","tb2_note","tb2_date") VALUES (DEFAULT,DEFAULT,DEFAULT,DEFAULT);
- VALUES
INSERT statements use the VALUES syntax can insert multiple lines, separated by commas.
Input
INSERT INTO exmp_tb1 (tb1_name,tb1_sex,tb1_address,tb1_number) VALUES('David','male','NewYork','01015827875'),('Rachel','female','NewYork','01015827749'),('Monica','female','NewYork','010158996743');
Output
INSERT INTO "public"."exmp_tb1" ("tb1_name","tb1_sex","tb1_address","tb1_number") VALUES ('David','male','NewYork','01015827875'); INSERT INTO "public"."exmp_tb1" ("tb1_name","tb1_sex","tb1_address","tb1_number") VALUES ('Rachel','female','NewYork','01015827749'); INSERT INTO "public"."exmp_tb1" ("tb1_name","tb1_sex","tb1_address","tb1_number") VALUES ('Monica','female','NewYork','010158996743');
- ON DUPLICATE KEY UPDATE
INSERT uses the ON DUPLICATE KEY UPDATE clause to update existing rows.
Input
# ON DUPLICATE KEY UPDATE (If new data will cause a duplicate value in the primary/unique key, UPDATE will work. Otherwise, INSERT will work.) INSERT INTO exmp_tb2(tb2_id,tb2_price) VALUES(3,12.3) ON DUPLICATE KEY UPDATE tb2_price=12.3; INSERT INTO exmp_tb2(tb2_id,tb2_price) VALUES(4,12.3) ON DUPLICATE KEY UPDATE tb2_price=12.3; INSERT INTO exmp_tb2(tb2_id,tb2_price,tb2_note) VALUES(10,DEFAULT,DEFAULT) ON DUPLICATE KEY UPDATE tb2_price=66.6; INSERT INTO exmp_tb2(tb2_id,tb2_price,tb2_note,tb2_date) VALUES(11,DEFAULT,DEFAULT,DEFAULT) ON DUPLICATE KEY UPDATE tb2_price=66.6;
Output
-- ON DUPLICATE KEY UPDATE (If new data will cause a duplicate value in the primary/unique key, UPDATE will work. Otherwise, INSERT will work.) INSERT INTO "public"."exmp_tb2" ("tb2_id","tb2_price") VALUES (3,12.3); INSERT INTO "public"."exmp_tb2" ("tb2_id","tb2_price") VALUES (4,12.3); INSERT INTO "public"."exmp_tb2" ("tb2_id","tb2_price","tb2_note") VALUES (10,DEFAULT,DEFAULT); INSERT INTO "public"."exmp_tb2" ("tb2_id","tb2_price","tb2_note","tb2_date") VALUES (11,DEFAULT,DEFAULT,DEFAULT);
- SET
MySQL INSERT...SET statement inserts rows based on explicitly specified values.
Input
# INSERT INTO SET (Data records can be inserted specially. One record can be inserted at a time, and batch insertion is not supported.) INSERT INTO exmp_tb2 SET tb2_price=56.1,tb2_note='unbelievable',tb2_date='2018-11-13'; INSERT INTO exmp_tb2 SET tb2_price=99.9,tb2_note='perfect',tb2_date='2018-10-13'; INSERT INTO exmp_tb2 SET tb2_id=9,tb2_price=99.9,tb2_note='perfect',tb2_date='2018-10-13';
Output
-- INSERT INTO SET (Data records can be inserted specially. One record can be inserted at a time, and batch insertion is not supported.) INSERT INTO "public"."exmp_tb2" ("tb2_price","tb2_note","tb2_date") VALUES (56.1,'unbelievable','2018-11-13'); INSERT INTO "public"."exmp_tb2" ("tb2_price","tb2_note","tb2_date") VALUES (99.9,'perfect','2018-10-13'); INSERT INTO "public"."exmp_tb2" ("tb2_id","tb2_price","tb2_note","tb2_date") VALUES (9,99.9,'perfect','2018-10-13');
UPDATE
In MySQL, UPDATE allows the following keywords: LOW_PRIORITY, ORDER BY, LIMIT, and IGNORE. GaussDB(DWS) does not support these keywords, and DSC will convert them.
- LOW_PRIORITY
With the LOW_PRIORITY modifier, execution of UPDATE is delayed.
Input
# LOW_PRIORITY UPDATE LOW_PRIORITY employees SET department_id=2;
Output
-- LOW_PRIORITY UPDATE "public"."employees" SET "department_id" = 2;
- ORDER_BY
In MySQL, if an UPDATE statement includes an ORDER BY clause, the rows will be updated in the order specified by the clause.
Input
# ORDER BY UPDATE employees SET department_id=department_id+1 ORDER BY id;
Output
-- ORDER BY UPDATE "public"."employees" SET "department_id" = department_id+1;
- LIMIT
UPDATE LIMIT syntax can be used to limit the scope. A clause is a limit on row matching. As long as the rows that satisfy the clause are found, the statements will stop, regardless of whether they have actually changed.
Input
# LIMIT UPDATE employees SET department_id=department_id+1 LIMIT 3 ; UPDATE employees SET department_id=department_id+1 LIMIT 3 , 10 ; # LIMIT + OFFSET UPDATE employees SET department_id=department_id+1 LIMIT 3 OFFSET 2; # LIMIT + ORDER BY UPDATE employees SET department_id=department_id+1 ORDER BY fname LIMIT 3 ; # LIMIT + WHERE + ORDER BY UPDATE employees SET department_id=department_id+1 WHERE id<5 ORDER BY fname LIMIT 3 ; # LIMIT + WHERE + ORDER BY + OFFSET UPDATE employees SET department_id=department_id+1 WHERE id<5 ORDER BY fname LIMIT 3 OFFSET 2 ;
Output
-- LIMIT UPDATE "public"."employees" SET "department_id" = department_id+1; UPDATE "public"."employees" SET "department_id" = department_id+1; -- LIMIT + OFFSET UPDATE "public"."employees" SET "department_id" = department_id+1; -- LIMIT + ORDER BY UPDATE "public"."employees" SET "department_id" = department_id+1; -- LIMIT + WHERE + ORDER BY UPDATE "public"."employees" SET "department_id" = department_id+1 WHERE id<5; -- LIMIT + WHERE + ORDER BY + OFFSET UPDATE "public"."employees" SET "department_id" = department_id+1 WHERE id<5;
- IGNORE
With the IGNORE modifier, the UPDATE statement does not abort even if errors occur during execution.
Input
# IGNORE UPDATE IGNORE employees SET department_id=3;
Output
-- IGNORE UPDATE "public"."employees" SET "department_id" = 3;
REPLACE
In MySQL, REPLACE allows the following keywords: LOW_PRIORITY, PARTITION, DELAYED, VALUES, and SET. The following examples are temporary migration solutions only.
REPLACE works exactly like INSERT, except that if an old row in the table has the same value as a new row for a primary key or unique index, the old row is deleted before the new row is inserted.
- LOW_PRIORITY
MySQL REPLACE supports the use of LOW_PRIORITY, which is converted by the Migration tool.
Input
# LOW_PRIORITY Replace LOW_PRIORITY INTO exmp_tb2 VALUES(1, '128.23', 'nice', '2018-10-11 19:00:00'); Replace LOW_PRIORITY INTO exmp_tb2 VALUES(2, DEFAULT, 'nice', '2018-12-14 19:00:00' ); Replace LOW_PRIORITY INTO exmp_tb2 VALUES(3, DEFAULT, 'nice', DEFAULT); Replace LOW_PRIORITY INTO exmp_tb2 (tb2_id, tb2_price) VALUES(5, DEFAULT); Replace LOW_PRIORITY INTO exmp_tb2 (tb2_id, tb2_price, tb2_note) VALUES(4, DEFAULT, DEFAULT);
Output
-- LOW_PRIORITY INSERT INTO "public"."exmp_tb2" VALUES (1,'128.23','nice','2018-10-11 19:00:00'); INSERT INTO "public"."exmp_tb2" VALUES (2,DEFAULT,'nice','2018-12-14 19:00:00'); INSERT INTO "public"."exmp_tb2" VALUES (3,DEFAULT,'nice',DEFAULT); INSERT INTO "public"."exmp_tb2" ("tb2_id","tb2_price") VALUES (5,DEFAULT); INSERT INTO "public"."exmp_tb2" ("tb2_id","tb2_price","tb2_note") VALUES (4,DEFAULT,DEFAULT);
- PARTITION
MySQL REPLACE supports explicit partitioning selection using the PARTITION keyword and a comma-separated name list for partitions, subpartitions, or both.
Input
replace INTO employees PARTITION(p3) VALUES (19, 'Frank1', 'Williams', 1, 2); replace INTO employees PARTITION(p0) VALUES (4, 'Frank1', 'Williams', 1, 2); replace INTO employees PARTITION(p1) VALUES (9, 'Frank1', 'Williams', 1, 2); replace INTO employees PARTITION(p2) VALUES (10, 'Frank1', 'Williams', 1, 2); replace INTO employees PARTITION(p2) VALUES (11, 'Frank1', 'Williams', 1, 2);
Output
INSERT INTO "public"."employees" VALUES (19,'Frank1','Williams',1,2); INSERT INTO "public"."employees" VALUES (4,'Frank1','Williams',1,2); INSERT INTO "public"."employees" VALUES (9,'Frank1','Williams',1,2); INSERT INTO "public"."employees" VALUES (10,'Frank1','Williams',1,2); INSERT INTO "public"."employees" VALUES (11,'Frank1','Williams',1,2);
- DELAYED
DELAYED INSERT and REPLACE operations were deprecated in MySQL 5.6. In MySQL 5.7, DELAYED was not supported. The server recognizes but ignores the DELAYED keyword, handles REPLACE as a non-delayed one, and generates an ER_WARN_LEGACY_SYNTAX_CONVERTED warning. (REPLACE DELAYED is no longer supported, and the statement is converted to REPLACE.) The keyword DELAYED will be deleted in later versions.
Input
#DELAYED INSERT DELAYED works only with MyISAM, MEMORY, ARCHIVE, and BLACKHOLE tables. #If you execute INSERT DELAYED with another storage engine, #you will get an error like this: ERROR 1616 (HY000): DELAYED option not supported Replace DELAYED INTO exmp_tb2 VALUES(10, 128.23, 'nice', '2018-10-11 19:00:00'); Replace DELAYED INTO exmp_tb2 VALUES(6, DEFAULT, 'nice', '2018-12-14 19:00:00'); Replace DELAYED INTO exmp_tb2 VALUES(7, 20, 'nice', DEFAULT); Replace DELAYED INTO exmp_tb2 (tb2_id, tb2_price) VALUES(11, DEFAULT); Replace DELAYED INTO exmp_tb2 (tb2_id, tb2_price, tb2_note) VALUES(12, DEFAULT, DEFAULT); Replace DELAYED INTO exmp_tb2 (tb2_id, tb2_price, tb2_note, tb2_date) VALUES(13, DEFAULT, DEFAULT, DEFAULT);
Output
--DELAYED INSERT DELAYED works only with MyISAM, MEMORY, ARCHIVE, and BLACKHOLE tables. --If you execute INSERT DELAYED with another storage engine, --you will get an error like this: ERROR 1616 (HY000): DELAYED option not supported. INSERT INTO "public"."exmp_tb2" VALUES (10,128.23,'nice','2018-10-11 19:00:00'); INSERT INTO "public"."exmp_tb2" VALUES (6,DEFAULT,'nice','2018-12-14 19:00:00'); INSERT INTO "public"."exmp_tb2" VALUES (7,20,'nice',DEFAULT); INSERT INTO "public"."exmp_tb2" ("tb2_id","tb2_price") VALUES (11,DEFAULT); INSERT INTO "public"."exmp_tb2" ("tb2_id","tb2_price","tb2_note") VALUES (12,DEFAULT,DEFAULT); INSERT INTO "public"."exmp_tb2" ("tb2_id","tb2_price","tb2_note","tb2_date") VALUES (13,DEFAULT,DEFAULT,DEFAULT);
- VALUES
MySQL REPLACE supports a statement to insert or delete multiple values, separated by commas.
Input
# If data is available, replacement will be performed. Otherwise, insertion will be performed. Replace INTO exmp_tb1 (tb1_id,tb1_name,tb1_sex,tb1_address,tb1_number) VALUES(17,'David','male','NewYork11','01015827875'),(18,'Rachel','female','NewYork22','01015827749'),(20,'Monica','female','NewYork','010158996743'); Replace INTO exmp_tb1 (tb1_id,tb1_name,tb1_sex,tb1_address,tb1_number) VALUES(17,'David1','male','NewYork11','01015827875'),(21,'Rachel','female','NewYork22','01015827749'),(22,'Monica','female','NewYork','010158996743'); Replace INTO exmp_tb1 (tb1_id,tb1_name,tb1_sex,tb1_address,tb1_number,tb1_date) VALUES(17,'David2',DEFAULT,'NewYork11','01015827875',DEFAULT),(18,'Rachel','female',DEFAULT,'01015827749','2018-12-14 10:44:20'),(DEFAULT,'Monica','female',DEFAULT,DEFAULT,'2018-12-14 10:44:20'); Replace INTO exmp_tb1 VALUES(DEFAULT,'David',DEFAULT,'NewYork11','01015827875',DEFAULT),(18,'Rachel','female',DEFAULT,'01015827749','2018-12-14 10:44:20'),(DEFAULT,'Monica','female',DEFAULT,DEFAULT,'2018-12-14 10:44:20');
Output
-- If data is available, replacement will be performed. Otherwise, insertion will be performed. INSERT INTO "public"."exmp_tb1" ("tb1_id","tb1_name","tb1_sex","tb1_address","tb1_number") VALUES (17,'David','male','NewYork11','01015827875'); INSERT INTO "public"."exmp_tb1" ("tb1_id","tb1_name","tb1_sex","tb1_address","tb1_number") VALUES (18,'Rachel','female','NewYork22','01015827749'); INSERT INTO "public"."exmp_tb1" ("tb1_id","tb1_name","tb1_sex","tb1_address","tb1_number") VALUES (20,'Monica','female','NewYork','010158996743'); INSERT INTO "public"."exmp_tb1" ("tb1_id","tb1_name","tb1_sex","tb1_address","tb1_number") VALUES (17,'David1','male','NewYork11','01015827875'); INSERT INTO "public"."exmp_tb1" ("tb1_id","tb1_name","tb1_sex","tb1_address","tb1_number") VALUES (21,'Rachel','female','NewYork22','01015827749'); INSERT INTO "public"."exmp_tb1" ("tb1_id","tb1_name","tb1_sex","tb1_address","tb1_number") VALUES (22,'Monica','female','NewYork','010158996743'); INSERT INTO "public"."exmp_tb1" ("tb1_id","tb1_name","tb1_sex","tb1_address","tb1_number","tb1_date") VALUES (17,'David2',DEFAULT,'NewYork11','01015827875',DEFAULT); INSERT INTO "public"."exmp_tb1" ("tb1_id","tb1_name","tb1_sex","tb1_address","tb1_number","tb1_date") VALUES (18,'Rachel','female',DEFAULT,'01015827749','2018-12-14 10:44:20'); INSERT INTO "public"."exmp_tb1" ("tb1_id","tb1_name","tb1_sex","tb1_address","tb1_number","tb1_date") VALUES (DEFAULT,'Monica','female',DEFAULT,DEFAULT,'2018-12-14 10:44:20'); INSERT INTO "public"."exmp_tb1" VALUES (DEFAULT,'David',DEFAULT,'NewYork11','01015827875',DEFAULT); INSERT INTO "public"."exmp_tb1" VALUES (18,'Rachel','female',DEFAULT,'01015827749','2018-12-14 10:44:20'); INSERT INTO "public"."exmp_tb1" VALUES (DEFAULT,'Monica','female',DEFAULT,DEFAULT,'2018-12-14 10:44:20');
- SET
MySQL REPLACE supports the use of SET settings, which the Migration tool will convert.
Input
replace INTO `runoob_datatype_test` VALUES (100, 100, 100, 0, 1); replace INTO `runoob_datatype_test` VALUES (100.23, 100.25, 100.26, 0.12,1.5); replace INTO `runoob_datatype_test` (dataType_numeric,dataType_numeric1) VALUES (100.23, 100.25); replace INTO `runoob_datatype_test` (dataType_numeric,dataType_numeric1,dataType_numeric2) VALUES (100.23, 100.25, 2.34); replace into runoob_datatype_test set dataType_numeric=23.1, dataType_numeric4 = 25.12 ;
Output
INSERT INTO "public"."runoob_datatype_test" VALUES (100,100,100,0,1); INSERT INTO "public"."runoob_datatype_test" VALUES (100.23,100.25,100.26,0.12,1.5); INSERT INTO "public"."runoob_datatype_test" ("datatype_numeric","datatype_numeric1") VALUES (100.23,100.25); INSERT INTO "public"."runoob_datatype_test" ("datatype_numeric","datatype_numeric1","datatype_numeric2") VALUES (100.23,100.25,2.34); INSERT INTO "public"."runoob_datatype_test" ("datatype_numeric","datatype_numeric4") VALUES (23.1,25.12);
