Question

我有以下功能

Function GetSearchField2dArray(tableName)
    sql = "SELECT * FROM "&tableName&" WHERE TEST IS NULL"

    set rstField = DataConn.execute(sql)

    Dim rv : rv = ConvertSqlResponseTo2dArray (rstField, "")

    set rstField = Nothing

    GetTCLSSearchFields2dArray = rv
End Function

此函数采用sql结果集并使用ConvertSqlResponseTo2dArray将其转换为2d数组。我已经确认rv确实是一个完美的阵列。

这是ConvertSqlResponseTo2dArray供参考：

Function ConvertSqlResponseTo2dArray(rstField, strExclude)
    iField_tmp = 0

    ReDim arrField(2, 0)
    For i = 0 To rstField.Fields.Count - 1
        If InStr(strExclude, "," & rstField.Fields(i).Name & ",") = 0 Then
            strFieldType = rstField.Fields(i).Type
            ReDim Preserve arrField(2, iField_tmp)
            arrField(0, iField_tmp) = rstField.Fields(i).Name
            If strFieldType = adDate Or strFieldType = adDBDate Or strFieldType = adDBTime Or strFieldType = adDBTimeStamp Then
                ' Date
                arrField(1, iField_tmp) = "date"
            ElseIf strFieldType = adSmallInt Or strFieldType = adInteger Or strFieldType = adTinyInt Or strFieldType = adUnsignedTinyInt Or strFieldType = adUnsignedSmallInt Or strFieldType = adUnsignedInt Or strFieldType = adBigInt Or strFieldType = adUnsignedBigInt Then
                ' Integer
                arrField(1, iField_tmp) = "num"
            ElseIf strFieldType = adSingle Or strFieldType = adDouble Or strFieldType = adCurrency Or strFieldType = adDecimal Or strFieldType = adVarNumeric Then
                ' Decimal
                arrField(1, iField_tmp) = "num"
            ElseIf strFieldTYpe = adBoolean Then
                ' Boolean
                arrField(1, iField_tmp) = "boolean"
            Else
                arrField(1, iField_tmp) = "string"
            End If
            iField_tmp = iField_tmp + 1
        End If
    Next

    ConvertSqlResponseTo2dArray = arrField
End Function

然后我有我正在使用它的代码

Session("SearchFields") = GetSearchField2dArray("Test1")

Session（“SearchFields”）为空，而不是数组。它返回之前它是一个2d数组，而不是返回后的二维数组。一直在努力奋斗近一个小时。

我已尝试将GetSearchField2dArray的结果设置为变量，但仍然存在相同的问题。

错字。 GetSearchField2dArray返回Empty，因为没有为其分配值。
函数的最后一行必须是GetSearchField2dArray = rv而不是GetTCLSSearchFields2dArray = rv。

请记住使用Option Explicit来防止此类混淆。

返回2d数组
