可以参考以下例子，table1.a为字符串，table2.b为数值 select a from Table1 where val(a) in (select b from Table2) or select a from Table1 where a in (select str(b) from Table2) or select a from Table1 where a in (select cstr(b) from Table2) o
可以参考以下例子，table1.a为字符串，table2.b为数值
select a from Table1 where val(a) in (select b from Table2)
or
select a from Table1 where a in (select str(b) from Table2)
or
select a from Table1 where a in (select cstr(b) from Table2)
or
select a from Table1 where a in (select format(b,'#####') from Table2)
