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.

  1. 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);
  2. 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);
  3. 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);
  4. 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);
  5. 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);
  6. 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');
  7. 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);
  8. 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.

  1. 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;
  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;
  3. 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;
  4. 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.

  1. 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);
  2. 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);
  3. 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);
  4. 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"  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');
  5. 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);
