如何读取文本文件并插入数据库

Question

我有很多文本文件，其内容如下：

LOG_NAME=LOGX1245;
LOT_NO=NA;
STEP=NA;
NO=CS84E869500115;
TIME_START=20190506 094715;
TIME_END=20190506 094715

我需要阅读文本文件并插入数据库。 列名称是第一个字段，值是第二个字段。 如何读取文本文件并将每一行插入数据库？

我要做的是：

For Each file In fso.GetFolder("C:\Data").Files
    Set otf = objFSO.OpenTextFile(file, 1)
    Do Until otf.AtEndOfStream
        line = otf.ReadLine

        If Mid(line, 1, 12) = "LOG_NAME" Then
            datalog = Trim(Split(line, "=")(1))
        End If

        If Mid(line, 1, 10) = "LOT_NO" Then
            PT = Trim(Split(line, "=")(1))
        End If

        If Mid(line, 1, 4) = "STEP" Then
            TestStep = Trim(Split(line, "=")(1))
        End If

        If Mid(line, 1, 11) = "NO" Then ...
    Loop
    otf.Close
Next

这是我要查询的地方。如何根据我从文本文件中获取的值查询SQL INSERT语句？有没有更简单的方法？

Dim query
Set rsObj = CreateObject("ADODB.Recordset")

query = "Insert in"

On Error Resume Next
rsObj.Open query, connObj

尝试以下代码

    Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objConn = CreateObject("ADODB.Connection")
objConn.Open "Provider=Microsoft.ACE.OLEDB.12.0; Data Source=C:\Users\Desktop\Data.accdb"

For Each objFile In objFSO.GetFolder("C:\Users\Desktop\Data").Files
    Set objDataFile = objFSO.OpenTextFile(objFile.Path, 1)
    arrData = Split(objDataFile.ReadAll, vbNewLine) 'store file data in array
    objDataFile.Close

    varValues = Empty: varFields = Empty
    For i = LBound(arrData) To UBound(arrData)
        arrRowData = Split(arrData(i), "=")
        varFields = varFields & "[" & arrRowData(0) & "]," 'square bracket to avoid reserve keyword as field name
        arrRowData(1) = Left(arrRowData(1), Len(arrRowData(1)) - 1) 'remove last semicolon
        varValues = varValues & "'" & arrRowData(1) & "',"
    Next
    varFields = Left(varFields, Len(varFields) - 1) 'remove last comma
    varValues = Left(varValues, Len(varValues) - 1) 'remove last comma
    objConn.Execute "INSERT INTO Data(" & varFields & ") VALUES(" & varValues & ")"
Next

Set objFSO = Nothing
objConn.Close
Set objConn = Nothing

我已经使用Access DB来测试代码。另外，我假设“数据”文件夹中的文本文件相似，并且只包含适合数据库插入的数据。

运行代码之前的数据库

运行代码后的数据库

我测试了Data文件夹中的2个文本文件。
