mysql存储过程对900w数据进行操作测试

新增索引：
LTER TABLE `tablename` ADD INDEX `sdhid` (`createTime`) USING BTREE ;
[SQL]ALTER TABLE `tablename` ADD INDEX `sdhid` (`createTime`) USING BTREE ;
受影响的行: 0
时间: 737.600s

[SQL]ALTER TABLE  tablename add INDEX jkjk(createTime) USING BTREE;
受影响的行: 0
时间: 1586.745s 26分钟

[SQL]delete from tablename where createTime< 95 limit 1;
受影响的行: 0
时间: 109.540s

createTime有索引时删除测试：
[SQL]ALTER TABLE  tablename add INDEX jkjk(createTime) USING BTREE;
受影响的行: 0
时间: 1586.745s 26分钟

[SQL]delete from tablename where createTime< 95 limit 1;
受影响的行: 0
时间: 109.540s

[SQL] delete from tablename where createTime< 95 order by createTime,id limit 1;
[Err] 1205 - Lock wait timeout exceeded; try restarting transaction

[SQL] delete from tablename where createTime< 95 order by createTime,id limit 1;
受影响的行: 0

受影响的行: 0
时间: 169.260s

[SQL]delete from tablename where createTime< 95 limit 1;
受影响的行: 0
时间: 153.959s

createTime无索引时删除测试：
[SQL]delete from tablename where createTime< 95 limit 1;
[Err] 1205 - Lock wait timeout exceeded; try restarting transaction

[SQL]delete from tablename where createTime< 95 limit 1;
[Err] 1205 - Lock wait timeout exceeded; try restarting transaction
