错误：com.mysql.jdbc.MysqlDataTruncation：数据截断：截断了不正确的DOUBLE值：通过删除

Question

I have this code:

bb.doCammand("delete  from models where model_id='" + del + "' OR model_name='" + del + "'");

I received this error:

Error:com.mysql.jdbc.MysqlDataTruncation: Data truncation: Truncated incorrect DOUBLE value: xd model_id and model_name are string.

How can I solve it?

Answer 1

Seems like a kind of typo in your query.

Assuming that del is a variable of String try to change the query regarding to this showcase:

"DELETE from models WHERE model_id =" + del + " OR model_name =" + del

It's better to avoid a concatenation at the end of the query.
