excel vba – 转换一个sql

有没有人有任何运气与vbamacros将转换此input：

update my_table set time = sysdate, randfield1 = 'FAKE', randfield5 = 'ME', the_field8 = 'test' where my_key = '84' ; 

进入这个输出？

 select count(*) from my_table where (randfield1 <> 'FAKE' or randfield5 <> 'ME' or the_field8 <> 'TEST') and my_key = '84'; 

更新（使用Remou的答案时会发生什么）：

input（我有第一张单元格A1的地方） –

 update my_table set time = sysdate, randfield1 = 'FAKE', randfield5 = 'ME', the_field8 = 'test' where my_key = '84' ; 

输出（一旦macros运行，第二张纸a1中产生的） –

 SELECT Count(*) FROM my_table WHERE () ) ) ) ) ) ) ) randfield1 <> 'FAKE' OR ) ) ) ) randfield5 <> 'ME' OR ) ) ) ) the_field8 <> 'test') ) ) ) ) AND my_key = '84' ; 

Answer 1

我仍然不确定你想要什么，但无论如何：

 Dim r As Range Dim cl As Range Dim s As String Dim c As String Dim arys As Variant Dim i As Long, j As Long ''Assuming an existing worksheet Set r = Sheet1.UsedRange j = Sheet2.UsedRange.Rows.Count For Each cl In r.Cells c = cl.Value ''Fake spaces Do While InStr(c, Chr(160)) > 0 c = Replace(c, Chr(160), "") Loop ''Real spaces c = Trim(c) If c = ";" Then arys = Split(s, vbCrLf) For i = 0 To UBound(arys) Sheet2.Cells(j, 1) = arys(i) j = j + 1 Next ''Layout j = j + 2 ElseIf UCase(c) Like "UPDATE*" Then s = "SELECT Count(*) FROM " & Replace(c, "update", "", , , vbTextCompare) s = s & vbCrLf & "WHERE (" ElseIf UCase(c) Like "WHERE*" Then s = s & Replace(c, "where", "AND", , , vbTextCompare) s = s & vbCrLf & ";" ElseIf Left(UCase(c), 3) <> "SET" Then c = Replace(c, "=", "<>") If Right(c, 1) = "," Then s = s & Left(c, Len(c) - 1) & vbCrLf & "OR " Else s = s & c & ")" & vbCrLf End If End If Next

那么，这至less适用于您的示例input…

 Sub NotExtensibleInTheLeast() Dim sql As String sql = _ "update my_table " & Chr$(10) & _ " set time = sysdate, " & Chr$(10) & _ " randfield1 = 'FAKE', " & Chr$(10) & _ " randfield5 = 'ME', " & Chr$(10) & _ " the_field8 = 'test' " & Chr$(10) & _ " where my_key = '84' " & Chr$(10) & _ " ;" Dim newSql newSql = sql newSql = Replace$(newSql, "where", ") and") newSql = Replace$(newSql, "update", "select count(*) from") newSql = Replace$(newSql, "set", "where (") newSql = Excel.Application.WorksheetFunction.Substitute(newSql, "=", Chr$(22), 5) newSql = Replace$(newSql, "=", "<>") newSql = Replace$(newSql, Chr$(22), "=") newSql = Replace$(newSql, ",", " or ") newSql = Replace$(newSql, "time <> sysdate or", vbNullString) MsgBox newSql End Sub
