Question

這裏是我的查詢：

 cs.SqlWhereClause = "([IsDiscontinued] = 0 AND [Visible] = 1 AND [ProductAvailableForSale] = 1) AND "; 
     cs.SqlWhereClause += "[LongDescription] like '%ct.%tw.%' "; 
     cs.SqlWhereClause += "OR ([LongDescription] like '%\"' "; 
     cs.SqlWhereClause += "OR [LongDescription] like '%ct.%' "; 
     cs.SqlWhereClause += "OR [LongDescription] like '%14k%' "; 
     cs.SqlWhereClause += "OR [LongDescription] like '%18k%' "; 
     cs.SqlWhereClause += "OR [LongDescription] like '%10k%' "; 
     cs.SqlWhereClause += "OR [LongDescription] like '%12k%' "; 
     cs.SqlWhereClause += "OR [LongDescription] like '%cttw%')"; 

這裏是我想要返回什麼內容：

項目是：不停產，可見，和可供出售

AND

項目，其longdescriptions是LIKE '％ct.tw.％' 或像 '％克拉％' 等。

加入價格調整匯率在第一個OR之後和最後一個OR之後的合併給我錯誤。我一直無法調試它。有任何想法嗎？

您應該在第一個或第一個之前添加第一個參數。像這樣：

cs.SqlWhereClause = "([IsDiscontinued] = 0 AND [Visible] = 1 AND [ProductAvailableForSale] = 1) AND "; 
cs.SqlWhereClause += "([LongDescription] like '%ct.%tw.%' "; 
cs.SqlWhereClause += "OR [LongDescription] like '%\"' "; 
cs.SqlWhereClause += "OR [LongDescription] like '%ct.%' "; 
cs.SqlWhereClause += "OR [LongDescription] like '%14k%' "; 
cs.SqlWhereClause += "OR [LongDescription] like '%18k%' "; 
cs.SqlWhereClause += "OR [LongDescription] like '%10k%' "; 
cs.SqlWhereClause += "OR [LongDescription] like '%12k%' "; 
cs.SqlWhereClause += "OR [LongDescription] like '%cttw%')";
