如何将excel表中的数据插入到数据库表中？

Sri*_*asR 0 excel vba excel-2003 teradata

我需要将 Excel 工作表中的数据插入到 teradata 表中。我需要使用宏来完成这项工作。

我在 Excel 表中有数据，例如

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

很快

我需要在 Excel 工作表中保留一个按钮并为该按钮分配一个宏，以便当我单击该按钮时，Excel 工作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，他将用数据填充该表，然后单击excel中的按钮，数据必须插入到数据库表中。我更喜欢使用宏来做到这一点..

谢谢大家。

我创建了将 Excel 表格转换为多个插入命令的函数。

将此复制到模块中，然后在公式中，将需要插入的单元格的值设置为第一个参数，第二个范围应为列名（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，则默认使用工作表名称。

在您的情况下，电子表格应如下所示：

+---+------+------+------+------+-----------------------------------------+
|   | A    | B    | C    | D    | E                                       |
+---+------+------+------+------+-----------------------------------------+
| 1 | COL1 | COL2 | COL3 | COL4 |                                         |

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)）：

如果您有大量数据要插入，您可能不需要在每个命令中使用 INSERT INTO，然后只需在第一行（以及每 500 个）中使用 Insert2DB 函数，其余的只使用 Insert2DBValues：

这将为您提供以下命令：

最后，如果你使用 MySQL，字符串的转义是不同的，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

        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
