如何将Excel工作表中的数据插入数据库表?

我需要将excel表中的数据插入到teradata表中。 我需要使用MACRO来完成。

我有像中文这样的excel表中的数据

COL1  COL2 COL3 COL4
1      2    3     4
2      5    8     10
.
.
等等

我需要在excel表中保留一个按钮,并为该按钮分配一个宏,这样当我点击按钮时,excel表中的行应插入到数据库表中。

要求是我将空的excel表发送给该人,他将用数据填写表单,然后单击excel中的按钮,数据必须插入到数据库表中。 我更喜欢用宏来做这个..

谢谢大家。

我创建了将Excel表格转换为多个插入命令的函数。

将其复制到模块中,然后在公式中,将第一个参数设置为需要插入的单元格的值,第二个范围应该是列的名称(按F4将其设置为常量),第三个(可选)表的名称。如果未指定表名,则表的名称将用作默认值。

在您的情况下,这是电子表格的样子:

+---+------+------+------+------+-----------------------------------------+
|   | A    | B    | C    | D    | E                                       |
+---+------+------+------+------+-----------------------------------------+
| 1 | COL1 | COL2 | COL3 | COL4 |                                         |
+---+------+------+------+------+-----------------------------------------+
| 2 | 1    | 2    | 3    | 4    | =Insert2DB(A2:D2,$A$1:$D$1,"TableName") |
+---+------+------+------+------+-----------------------------------------+
| 3 | 2    | 5    | 8    | 10   | =Insert2DB(A3:D3,$A$1:$D$1,"TableName") |
+---+------+------+------+------+-----------------------------------------+

这将为您生成这两个查询:

INSERT INTO TableName ([COL1],[COL2],[COL3],[COL4]) VALUES (1,2,3,4)
INSERT INTO TableName ([COL1],[COL2],[COL3],[COL4]) VALUES (2,5,8,10)

这是函数(适用于Microsoft SQL(TSQL):

    Function Insert2DB(InputRange As Range, Optional ColumnsNames As Variant, Optional TableName As Variant)

      Dim rangeCell As Range
      Dim InsertValues As String
      Dim CellValue As String
      Dim C As Range

        Dim AllColls As String
        Dim SingleCell As Range
        Dim TableColls As String

    InsertValues = ""

    'Start Loop
    For Each rangeCell In InputRange.Cells

    'Recognize data type
    Set C = rangeCell
        If IsEmpty(C) Then
                'DataType is NULL then NULL
                CellValue = "NULL"
            ElseIf Application.IsText(C) Then
                'DataType is VARCHAR or CHAR
                CellValue = "'" & Trim(rangeCell.Value) & "'"
            ElseIf Application.IsLogical(C) Then
                'DataType is bit eg. TRUE / FALSE
                    If rangeCell.Value = True Then
                        CellValue = "1"
                    ElseIf rangeCell.Value = False Then
                        CellValue = "0"
                    End If
            ElseIf Application.IsErr(C) Then
                'If there is an ERROR in cell, the statment will return 0
                CellValue = "NULL"
            ElseIf IsDate(C) Then
                'DataType is DATE or DATETIME, in case it is DATE specifying HH:mm:ss would do no harm
                CellValue = "'" & VBA.Format(rangeCell.Value, "yyyymmdd hh:mm:ss") & "'"
            ElseIf InStr(1, C.Text, ":") <> 0 Then
                'DataType is TIME
                CellValue = "'" & VBA.Format(rangeCell.Value, "hh:mm:ss") & "'"
            ElseIf IsNumeric(C) Then
                'DataType is number
                CellValue = rangeCell.Value
        End If

    If (Len(InsertValues) > 0) Then
        InsertValues = InsertValues + "," + CellValue
    Else
        InsertValues = CellValue
    End If

    Next rangeCell
    'END Loop

    If IsMissing(ColumnsNames) Then
        TableColls = ""
        Else

        For Each SingleCell In ColumnsNames.Cells
            If Len(AllColls) > 0 Then
                     AllColls = AllColls + "," + "[" + Trim(Replace(SingleCell.Value, Chr(160), "")) + "]"
            Else
                    AllColls = "[" + Trim(Replace(SingleCell.Value, Chr(160), "")) + "]"
            End If
        Next SingleCell
        TableColls = " (" & AllColls & ")"
    End If


    'If TableName is not set, then take the name of a sheet
    If IsMissing(TableName) = True Then
        TableName = ActiveSheet.Name
    Else
    TableName = TableName
    End If

    'Set the return value
        Insert2DB = "INSERT INTO " & TableName & TableColls & " VALUES (" & InsertValues & ")"

    End Function

如果你要插入很多数据,你可能不需要在每个命令中使用INSERT INTO,然后在第一行(和每500个)使用Insert2DB函数,其余只使用Insert2DBValues:

+---+------+------+------+------+-----------------------------------------------+
|   | A    | B    | C    | D    | E                                             |
+---+------+------+------+------+-----------------------------------------------+
| 1 | COL1 | COL2 | COL3 | COL4 |                                               |
+---+------+------+------+------+-----------------------------------------------+
| 2 | 1    | 2    | 3    | 4    | =Insert2DB(B3:E3,$B$2:$E$2,"TableName")       |
+---+------+------+------+------+-----------------------------------------------+
| 3 | 2    | 5    | 8    | 10   | =Insert2DBValues(A3:D3,$A$1:$D$1,"TableName") |
+---+------+------+------+------+-----------------------------------------------+

这将为您提供以下命令:

INSERT INTO TableName ([COL1],[COL2],[COL3],[COL4]) VALUES (1,2,3,4)
,(2,5,8,10)


Function Insert2DBValues(InputRange As Range, Optional ColumnsNames As Variant, Optional TableName As Variant)

  Dim rangeCell As Range
  Dim InsertValues As String
  Dim CellValue As String
  Dim C As Range

    Dim AllColls As String
    Dim SingleCell As Range
    Dim TableColls As String

InsertValues = ""

'Start Loop
For Each rangeCell In InputRange.Cells

'Recognize data type
Set C = rangeCell
    If IsEmpty(C) Then
            'DataType is NULL then NULL
            CellValue = "NULL"
        ElseIf Application.IsText(C) Then
            'DataType is VARCHAR or CHAR
            CellValue = "'" & Trim(rangeCell.Value) & "'"
        ElseIf Application.IsLogical(C) Then
            'DataType is bit eg. TRUE / FALSE
                If rangeCell.Value = True Then
                    CellValue = "1"
                ElseIf rangeCell.Value = False Then
                    CellValue = "0"
                End If
        ElseIf Application.IsErr(C) Then
            'If there is an ERROR in cell, the statment will return 0
            CellValue = "NULL"
        ElseIf IsDate(C) Then
            'DataType is DATE or DATETIME, in case it is DATE specifying HH:mm:ss would do no harm
            CellValue = "'" & VBA.Format(rangeCell.Value, "yyyy-mm-dd hh:mm:ss") & "'"
        ElseIf InStr(1, C.Text, ":") <> 0 Then
            'DataType is TIME
            CellValue = "'" & VBA.Format(rangeCell.Value, "hh:mm:ss") & "'"
        ElseIf IsNumeric(C) Then
            'DataType is number
            CellValue = rangeCell.Value
    End If

If (Len(InsertValues) > 0) Then
    InsertValues = InsertValues + "," + CellValue
Else
    InsertValues = CellValue
End If

Next rangeCell
'END Loop

If IsMissing(ColumnsNames) Then
    TableColls = ""
    Else

    For Each SingleCell In ColumnsNames.Cells
        If Len(AllColls) > 0 Then
                 AllColls = AllColls + "," + "[" + Trim(Replace(SingleCell.Value, Chr(160), "")) + "]"
        Else
                AllColls = "[" + Trim(Replace(SingleCell.Value, Chr(160), "")) + "]"
        End If
    Next SingleCell
    TableColls = " (" & AllColls & ")"
End If


'If TableName is not set, then take the name of a sheet
If IsMissing(TableName) = True Then
    TableName = ActiveSheet.Name
Else
TableName = TableName
End If

'Set the return value
    Insert2DBValues = ",(" & InsertValues & ")"

End Function

最后,如果你使用MySQL,有不同的字符串转义,所以在这种情况下使用Insert2DBMySQL:

    Function Insert2DBMySQL(InputRange As Range, Optional ColumnsNames As Variant, Optional TableName As Variant)

      Dim rangeCell As Range
      Dim InsertValues As String
      Dim CellValue As String
      Dim C As Range

        Dim AllColls As String
        Dim SingleCell As Range
        Dim TableColls As String

    InsertValues = ""

    'Start Loop
    For Each rangeCell In InputRange.Cells

    'Recognize data type
    Set C = rangeCell
        If IsEmpty(C) Then
                'DataType is NULL then NULL
                CellValue = "NULL"
            ElseIf Application.IsText(C) Then
                'DataType is VARCHAR or CHAR
                CellValue = "'" & Trim(rangeCell.Value) & "'"
            ElseIf Application.IsLogical(C) Then
                'DataType is bit eg. TRUE / FALSE
                    If rangeCell.Value = True Then
                        CellValue = "1"
                    ElseIf rangeCell.Value = False Then
                        CellValue = "0"
                    End If
            ElseIf Application.IsErr(C) Then
                'If there is an ERROR in cell, the statment will return 0
                CellValue = "NULL"
            ElseIf IsDate(C) Then
                'DataType is DATE or DATETIME, in case it is DATE specifying HH:mm:ss would do no harm
                CellValue = "'" & VBA.Format(rangeCell.Value, "yyyy-mm-dd hh:mm:ss") & "'"
            ElseIf InStr(1, C.Text, ":") <> 0 Then
                'DataType is TIME
                CellValue = "'" & VBA.Format(rangeCell.Value, "hh:mm:ss") & "'"
            ElseIf IsNumeric(C) Then
                'DataType is number
                CellValue = rangeCell.Value
        End If

    If (Len(InsertValues) > 0) Then
        InsertValues = InsertValues + "," + CellValue
    Else
        InsertValues = CellValue
    End If

    Next rangeCell
    'END Loop

    If IsMissing(ColumnsNames) Then
        TableColls = ""
        Else

        For Each SingleCell In ColumnsNames.Cells
            If Len(AllColls) > 0 Then
                     AllColls = AllColls + "," + "" + Trim(Replace(SingleCell.Value, Chr(160), "")) + ""
            Else
                    AllColls = "" + Trim(Replace(SingleCell.Value, Chr(160), "")) + ""
            End If
        Next SingleCell
        TableColls = " (" & AllColls & ")"
    End If


    'If TableName is not set, then take the name of a sheet
    If IsMissing(TableName) = True Then
        TableName = ActiveSheet.Name
    Else
    TableName = TableName
    End If

    'Set the return value
        Insert2DBMySQL = "INSERT INTO " & TableName & TableColls & " VALUES (" & InsertValues & ");"

    End Function
