INSERT

INSERT插入形式包括：HIGH_PRIORITY、LOW_PRIORITY、PARTITION、DELAYED、IGNORE、VALUES以及ON DUPLICATE KEY UPDATE。

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);

PARTITION

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);
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

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_gender,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_gender","tb1_address","tb1_number") VALUES ('David','male','NewYork','01015827875');
INSERT INTO "public"."exmp_tb1" ("tb1_name","tb1_gender","tb1_address","tb1_number") VALUES ('Rachel','female','NewYork','01015827749');
INSERT INTO "public"."exmp_tb1" ("tb1_name","tb1_gender","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');
