这句语句错在哪里？

[frankfish]

"SELECT XSSL FROM TT_SALE WHERE (YEAR(SDATE) = 2005) AND (MONTH(SDATE) = " & mon & ") AND (SUPPLIER_ID = " & stri & ")"

这句话是vb里的 不能执行， 但是把stri变量改成一个具体的值就能执行了 ，如果把这个值赋值给stri变量就不能支行了

stri是string supplier_id在SQL里是Char
请问错在哪里？

用引号引住：

"SELECT XSSL FROM TT_SALE WHERE (YEAR(SDATE) = 2005) AND (MONTH(SDATE) = " & mon & ") AND (SUPPLIER_ID = '" & stri & "')"

--try
"SELECT XSSL FROM TT_SALE WHERE (YEAR(SDATE) = 2005) AND (MONTH(SDATE) = " & mon & ") AND (SUPPLIER_ID = '" & stri & "')"

一楼正解，sql里的字符串要加单引号的
