多值字段的模糊查询 发帖心情

Post By：2019/2/10 12:39:00 [只看该作者]

老师新年好！对于多值字段的查询，如何通过代码设置含某个值的查询，比如字段A的中含有XXX，YYY，ZZZ中的部分或全部，如何将其中含有YYY的行选出来。谢谢

Tables("表A").filter = "第一列 like '%YYY%'"

谢谢！

下面问题代码的问题在哪里，提示了Like前缺少运算符，应该如何改才正确？

Dim Cols1() As String = {"xm","sfzhm","xb","mz","xh","nj","bj","xq","zxzt","xx","xslx","zmcl","lrr","lrsj"}

Dim Cols2() As String ={"xm","sfzhm","xb","mz","xh","nj","bj","xq","zxzt","xx","xslx","zmcl","lrr","lrsj"}

Dim fil As String="like '%YYY%' And sfytjmxzf='False'"

For Each dr1 As DataRow In DataTables("xszxztb").Select("xsxm"=fil)

Dim dr2 As DataRow = DataTables("mxzfb").AddNew()

For i As Integer = 0 To Cols1.Length -1

dr2(Cols2(i)) = dr1(Cols1(i))

dr1("sfytjmxzf")=True

其中：xsxm 为表xsxztb的一个多值字段

改成：Dim fil As String="like %YYY% And sfytjmxzf='False'"

For Each dr1 As DataRow In DataTables("xszxztb").Select(xsxm=fil)

...

后又提示 xsxm没有定义，如果把xsxm 改成：“xsxm”,不提示错误，但没有把符合条件的记录添加到目标表

谢谢！
