Datatable選擇多個條件SQL查詢問題

Question

從This question，其答案几乎是我的答案。但我面臨着一些SQL查詢的問題，我有以下的語句在VB

Dim results As DataRow() = table.Select("A = 'foo' AND B = 'bar' AND C = 'baz'") 

我要放置在變量foo, bar and baz和使用，在上述聲明的變量。

Dim Varfoo As String = "foo" 
Dim Varbar As String = "bar" 
Dim Varbaz As String = "baz" 

我設法在聲明一個變量

Dim results As DataRow() = table.Select("A = " + Varfoo) 

但如何與變量插入多個排序表達式？

編輯：我得到了它的維卡斯如下答覆解決;

Dim results As DataRow() = table.Select("A = '" & Varfoo & "' And B = '" & Varbar & "' And C = '" & Varbaz & "'") 

Answer 1

你試過

Dim results As DataRow() = table.Select("A = '" & Varfoo & "'") 

編輯

對於OR操作

Dim results As DataRow() = table.Select("A = '" & Varfoo & "' OR B = '" & Varbar & "' OR C = '" & Varbaz & "'") 

並操作

Dim results As DataRow() = table.Select("A = '" & Varfoo & "' AND B = '" & Varbar & "' AND C = '" & Varbaz & "'")
