sql2005 + VB6.0 在VB6.0中拼SQL 注意"()"
今天在调试的过程中发现 在vb中拼SQL的时候发现"()" 作用很大
eg: table: T_TEST col : T_KB int ,S_CD int ,Z_SU int
dim gcstrT_1 ,gcstrT_3 as integer
gcstrT_1 = 1
gcstrT_3 = 3
strWhere = strWhere & "……"
strWhere = strWhere & "AND ((T_KB = " & gcstrT_1 &; ") " '注意点 AND 后面需要一个括号 "("
strWhere = strWhere & "OR "
strWhere = strWhere & " (T_KB = " & gcstrT_3 & " "
strWhere = strWhere & " AND S_CD IS NOT NULL "
strWhere = strWhere & " AND Z_SU > 0 )) " '注意点 AND 后面需要一个括号 ")"
AND 后面的条件是一个整体,所以加"()"
