老师,list有50万个,int型数字,只看文件大小2M左右。
你看看我的测试案例
表DDL
greatsql> show create table t2\G
*************************** 1. row ***************************
Table: t2
Create Table: CREATE TABLE `t2` (
`id` int NOT NULL,
`addr` varchar(10) DEFAULT NULL,
`ui` json DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB
数据库版本
greatsql> \s
...
Server version: 8.0.25-17 GreatSQL, Release 17, Revision 4733775f703
查看相应配置参数

生成测试数据
#初始化sql文件
$ cat /tmp/t2.sql
truncate table t2;
insert into t2 values(1,'xxx','{"0":"[
#生成50万个INT
for i in $(seq 1 500000);do echo -n "$i,"; done >> /tmp/t2.sql
#将这50万个INT拼凑到sql中,结果sql内容类似这样
truncate table t2;
insert into t2 values(1,'xxx','{"0":"[1,2,3,4,5...
499997,499998,499999,500000]"}');
执行SQL,并不会报错
greatsql> source /tmp/t2.sql;
Query OK, 0 rows affected (0.03 sec)
Query OK, 1 row affected (0.17 sec)
greatsql> select length(ui), char_length(ui) from t2;
+------------+-----------------+
| length(ui) | char_length(ui) |
+------------+-----------------+
| 3388905 | 3388905 |
