kettle to import data into shardingsphere-proxy:Parameter index out of bounds

[Huletian]

When I use kettle to import data into shardingsphere-proxy, some table wile appear:caused by : Java sql. SQLException: Parameter index out of bounds. 23393 is not between valid values of 1 and 23392。

But,I am sure that my orginal table is consistent with the target table,and this problem will not occur when I change the target to MySQL sub database.

I used kettle to write a simple transfer,a table input and table outpit, the number of table output copies is 20,and the number of each submission is 3000 , Of Course，after reducing those two items,this error will not occur,but it will be too slow,I hope to help solve it. I put my table creation statement below (sharding key: school_code)

`

@Huletian Can you provide more information——ShardingSphere version and your sharding configuration?

Hi @Huletian Could you try the ShardingSphere 5.1.1? We did some enhancements about batched statements in https://github.com/apache/shardingsphere/issues/16124.

Hi @Huletian Could you try the ShardingSphere 5.1.1? We did some enhancements about batched statements in #16124.

I tried 5.1.1, but some tables will still throw this exception. My concurrency is not very large, and only some tables will have this problem. I want to ask, is the problem caused by the column type of the table?

Could you try finding out which SQL caused the exception?

I also want to find the SQL that throws an exception, but I can't find it. Sorry
