请帮我修改SELECT语句，使其覆盖整个表（不仅仅是“TestCase”列）？

尝试将SELECT查询更改为“SELECT * FROM ImportFromExcel WHERE col1 LIKE？OR col2 LIKE？or col3 LIKE？; ...”，但它无效。

Answer 1

如果要在表格的所有列中搜索字符串您可以连接新列中的所有列值和搜索值。例如

SELECT * FROM ImportFromExcel 
WHERE Module
        & column1
        & column2 
        & column3 like '*substring*'

SQL在整个表中搜索字符串
