FROM information_schema.columns
WHERE TABLE_NAME='user' and TABLE_SCHEMA = database() )

您能否请尝试以下动态SQL：

这可能会有所帮助

declare @insertquery nvarchar(1000)
Declare @ColumnNames varchar(2000)
select @ColumnNames = COALESCE(@ColumnNames + ', ', '') + COLUMN_NAME
from 
    INFORMATION_SCHEMA.COLUMNS
where 
    TABLE_NAME='user' and TABLE_SCHEMA = database();

set @insertquery = N'insert into user_audit(' + @ColumnNames + ') SELECT * FROM `user` where id = NEW.id;

sp_executesql @insertquery

使用另一个表的列插入mysql表
