数据操作语句(DML)

本节主要介绍MySQL DML的迁移语法。迁移语法决定了关键字/功能的迁移方式。

本节包括以下内容：

INSERT
UPDATE
REPLACE

INSERT

INSERT插入形式包括：HIGH_PRIORITY、LOW_PRIORITY、PARTITION、DELAYED、IGNORE、多值插入以及ON DUPLICATE KEY UPDATE。GaussDB(DWS)不支持以上类型插入，DSC工具将会对其转换。

HIGH_PRIORITY

MySQL中如果指定HIGH_PRIORITY，则会覆盖LOW_PRIORITY选项的效果。

输入示例

# HIGH_PRIORITY 高优先级
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);

输出示例

-- HIGH_PRIORITY 高优先级
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

MySQL INSERT插入语句使用LOW_PRIORITY修饰符时，则执行该INSERT延迟。

输入示例

# LOW_PRIORITY 低优先级
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);

输出示例

-- LOW_PRIORITY 低优先级
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

当插入到分区表中时，可以控制哪些分区和子分区接受新行。

输入示例

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);

输出示例

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

在MySQL 5.7中，DELAYED关键字被接受，但被服务器忽略。

输入示例

# DELAYED 延迟
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);

输出示例

-- DELAYED 延迟
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

MySQL INSERT语句如果使用IGNORE修饰符，则执行INSERT语句时发生的错误将被忽略。

输入示例

# 如果表中已经存在相同的记录,则忽略当前新数据
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);

输出示例

-- 如果表中已经存在相同的记录,则忽略当前新数据
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（单语句多行值插入）

INSERT使用 VALUES语法的语句可以插入多行，以逗号分隔。

输入示例

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');

输出示例

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使用 ON DUPLICATE KEY UPDATE子句可以使现有行更新。

输入示例

#ON DUPLICATE KEY UPDATE 若该数据的主键值/ UNIQUE KEY 已经在表中存在,则执行更新操作, 即UPDATE;否则执行插入操作
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;

输出示例

--ON DUPLICATE KEY UPDATE 若该数据的主键值/ UNIQUE KEY 已经在表中存在,则执行更新操作, 即UPDATE;否则执行插入操作
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语句的形式插入基于明确指定的值的行。

输入示例

# INSERT INTO  SET 可以针对性的执行插入操作，但是一次只能插入一行数据，不能批量添加数据
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';

输出示例

-- INSERT INTO  SET 可以针对性的执行插入操作，但是一次只能插入一行数据，不能批量添加数据
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

MySQL的UPDATE操作形式包括：LOW_PRIORITY、ORDER BY、LIMIT 、IGNORE。GaussDB(DWS)不支持以上类型更新，DSC工具将会对其转换。

LOW_PRIORITY

MySQL UPDATE语句如果使用LOW_PRIORITY修饰符，则执行UPDATE延迟。

输入示例

#测试 LOW_PRIORITY 语法点
UPDATE LOW_PRIORITY employees SET department_id=2;

输出示例

--测试 LOW_PRIORITY 语法点
UPDATE "public"."employees" SET "department_id" = 2;

ORDER_BY

如果一个MySQL UPDATE语句包含一个 ORDER BY子句，则这些行将按照该子句指定的顺序更新。

输入示例

# 测试 ORDER BY 语法点
UPDATE  employees SET department_id=department_id+1  ORDER BY id;

输出示例

-- 测试 ORDER BY 语法点
UPDATE "public"."employees" SET "department_id" = department_id+1;

LIMIT

UPDATE LIMIT语法可以用来限制的范围。一个子句是一个行匹配的限制。只要发现满足该子句的行，语句就会停下来，不管它们是否真的发生了变化。

输入示例

#单独测试 LIMIT 语法点
UPDATE  employees SET department_id=department_id+1   LIMIT 3 ;
UPDATE  employees SET department_id=department_id+1   LIMIT 3 , 10 ;

#测试 LIMIT + OFFSET 语法点
UPDATE  employees SET department_id=department_id+1   LIMIT 3   OFFSET 2;

#测试 LIMIT + ORDER BY 语法点搭配使用
UPDATE  employees SET department_id=department_id+1 ORDER BY fname  LIMIT 3 ;

#测试 LIMIT + WHERE + ORDER BY 语法点搭配使用
UPDATE  employees SET department_id=department_id+1 WHERE id<5 ORDER BY  fname  LIMIT 3 ;

#测试 LIMIT + WHERE + ORDER BY + OFFSET 语法点搭配使用
UPDATE  employees SET department_id=department_id+1 WHERE id<5 ORDER BY  fname  LIMIT 3 OFFSET 2 ;

输出示例

--单独测试 LIMIT 语法点
UPDATE "public"."employees" SET "department_id" = department_id+1;
UPDATE "public"."employees" SET "department_id" = department_id+1;

--测试 LIMIT + OFFSET 语法点
UPDATE "public"."employees" SET "department_id" = department_id+1;

--测试 LIMIT + ORDER BY 语法点搭配使用
UPDATE "public"."employees" SET "department_id" = department_id+1;

--测试 LIMIT + WHERE + ORDER BY 语法点搭配使用
UPDATE "public"."employees" SET "department_id" = department_id+1 WHERE id<5;

--测试 LIMIT + WHERE + ORDER BY + OFFSET 语法点搭配使用
UPDATE "public"."employees" SET "department_id" = department_id+1 WHERE id<5;

IGNORE

MySQL UPDATE语句如果使用IGNORE修饰符，即使更新期间发生错误，update语句也不会中止。

输入示例

#测试 IGNORE 语法点
UPDATE IGNORE employees SET department_id=3;

输出示例

--测试 IGNORE 语法点
UPDATE "public"."employees" SET "department_id" = 3;

REPLACE

MySQL的REPLACE操作形式包括：LOW_PRIORITY、PARTITION 、DELAYED 、VALUES、SET；（下述迁移示例为临时迁移方案）

REPLACE的工作方式与INSERT完全相同，不同之处在于，如果表中的旧行与主键或唯一索引的新行具有相同的值，则在插入新行之前删除该旧行。

LOW_PRIORITY

MySQL REPLACE支持使用LOW_PRIORITY ，DSC工具将对其进行转换。

输入

# LOW_PRIORITY 低优先级
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);

输出

-- LOW_PRIORITY 低优先级
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支持使用PARTITION关键字和分区，子分区或两者的逗号分隔名称列表显式分区选择。

输入

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);

输出

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插入和替换在MySQL 5.6中被弃用。在MySQL 5.7中，DELAYED 不支持。服务器识别但忽略 DELAYED关键字，将替换处理为非延迟替换，并生成 ER_WARN_LEGACY_SYNTAX_CONVERTED警告。（“ REPLACE DELAYED不再被支持，语句被转换为REPLACE。 ”）DELAYED 关键字将在未来版本中被删除。

输入

#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);

输出

--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支持一条语句插入或删除多值，以逗号分隔。

输入

#有数据的话则替换replace，没有的话则插入新的数据同insert
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 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');

输出

--有数据的话则替换replace，没有的话则插入新的数据同insert

INSERT INTO "public"."exmp_tb1"  VALUES (DEFAULT,'Monica','female',DEFAULT,DEFAULT,'2018-12-14 10:44:20');

SET

MySQL REPLACE支持使用SET设置值，DSC工具将对其转换。

输入

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 ;

输出

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);
