Question

这是我的问题：

      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%')";

这是我想要归还的内容：

以下项目：未停产，可见且可供销售

和

其长篇描述类似于'％ct.tw.％'的项目或类似'％ct。％'等等。

在第一个OR之后和最后一个OR之后添加括号是给我错误的。我无法调试它。任何想法？

你应该在第一个或之前添加第一个paranthesis。像这样：

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%')";

多个OR / AND。搜索子句无效
