查询帮助 - Where子句

Question

然后我有以下查询：

mysql_select_db($database_conndb1, $conndb1); 
$query_rsName = sprintf(" 
SELECT DISTINCT 
table1.search_id, table1.search1, table1.search2, table1.search3, table1.search4, table1.search5, table1.search6, table1.search7, table1.search8, table1.search9, table1.search10, table1.search11, table1.search12, table1.search13, table1.search14, table1.search15, table1.search16, table2.search_id 

FROM table1, table2 
WHERE 
table2.criteria1 = %s OR 
table2.criteria2 = %s OR 
table2.criteria3 = %s OR 
table2.criteria4 = %s OR 
table2.criteria5 = %s OR 
table2.criteria6 = %s OR 
table2.criteria7 = %s OR 
FIND_IN_SET(%s, table2.criteria8) OR 
table2.criteria9 = %s OR 
table2.criteria10 = %s OR 
table2.criteria11 = %s AND 
table1.search_id = table2.search_id 
ORDER BY 
table1.search2 DESC", 
GetSQLValueString($search1_rsName, "text"), 
GetSQLValueString($search2_rsName, "text"), 
GetSQLValueString($search3_rsName, "text"), 
GetSQLValueString($search4_rsName, "text"), 
GetSQLValueString($search5_rsName, "text"), 
GetSQLValueString($search6_rsName, "text"), 
GetSQLValueString($search7_rsName, "text"), 
GetSQLValueString($search8_rsName, "text"), 
GetSQLValueString($search9_rsName, "text"), 
GetSQLValueString($search10_rsName, "text"), 
GetSQLValueString($search11_rsName, "text")); 

然而，当查询是跑，它拉的所有记录，并做每个记录十次 - 不只是那些基于搜索条件。现在，如果我将OR更改为AND并选择全部11，则它应该可以正常工作。因此，它与OR操作数有关。但是，我无法弄清楚什么是错的。除OR以外，我还可以使用哪些操作数，以允许搜索者选择1,2,3或更多条件？

这是一个查询的地狱，我想它运行了很长时间。然而，在这里更正一个：

mysql_select_db($database_conndb1, $conndb1); 
$query_rsName = sprintf(" 
SELECT DISTINCT 
table1.search_id, table1.search1, table1.search2, table1.search3, table1.search4, table1.search5, table1.search6, table1.search7, table1.search8, table1.search9, table1.search10, table1.search11, table1.search12, table1.search13, table1.search14, table1.search15, table1.search16, table2.search_id 

FROM table1, table2 
WHERE (
table2.criteria1 = %s OR 
table2.criteria2 = %s OR 
table2.criteria3 = %s OR 
table2.criteria4 = %s OR 
table2.criteria5 = %s OR 
table2.criteria6 = %s OR 
table2.criteria7 = %s OR 
FIND_IN_SET(%s, table2.criteria8) OR 
table2.criteria9 = %s OR 
table2.criteria10 = %s OR 
table2.criteria11 = %s) AND 
table1.search_id = table2.search_id 
ORDER BY 
table1.search2 DESC", 
GetSQLValueString($search1_rsName, "text"), 
GetSQLValueString($search2_rsName, "text"), 
GetSQLValueString($search3_rsName, "text"), 
GetSQLValueString($search4_rsName, "text"), 
GetSQLValueString($search5_rsName, "text"), 
GetSQLValueString($search6_rsName, "text"), 
GetSQLValueString($search7_rsName, "text"), 
GetSQLValueString($search8_rsName, "text"), 
GetSQLValueString($search9_rsName, "text"), 
GetSQLValueString($search10_rsName, "text"), 
GetSQLValueString($search11_rsName, "text")); 

注意括号WHERE条款左右OR一部分。

SELECT DISTINCT 
table1.search_id, table1.search1, table1.search2, table1.search3, table1.search4, table1.search5, table1.search6, table1.search7, table1.search8, table1.search9, table1.search10, table1.search11, table1.search12, table1.search13, table1.search14, table1.search15, table1.search16, table2.search_id 

FROM table1 
join table2 on table1.search_id = table2.search_id 
WHERE 
table2.criteria1 = %s OR 
table2.criteria2 = %s OR 
table2.criteria3 = %s OR 
table2.criteria4 = %s OR 
table2.criteria5 = %s OR 
table2.criteria6 = %s OR 
table2.criteria7 = %s OR 
FIND_IN_SET(%s, table2.criteria8) OR

table2.criteria11 = %s 
ORDER BY
