excel的宏与VBA实践——建表语句

Sub createTableDDL()
    ‘自动创建建表语句
    ‘定义换行和TAB
    Ln = Chr(13) + Chr(10)
    TB = Chr(9)
    ‘定义脚本目录
    Dim dir AS String
    dir = "C:\CREATE_TABLE_DDL"
    Set FSOE = CreateObject("Scripting.FileSystemObject")
    If FSOE.folderexists(dir) = False Then
          MkDir dir
    End If
      
    ‘调用脚本定义
    Set SqlFileDDL = FSOE.CreateTextFile("C:\CREATE_TABLE_DDL\create_table_ddl.sql", True)
    ‘获得表名
    tableName = Trim(Cells(1, 2).Value)
    ‘获得表注释
    tableComment = Trim(Cells(1, 4).Value)
    ‘获得创建者
    createBy = Trim(Cells(1, 6).Value)
    Dim dt As Date
    dt = Format(Date, "yyyy-mm-dd")
    ‘获得当前日期
    createDate = dt
    ‘获得A列已使用的行数
    count_row_k = [A65536].End(xlUp).Row
    ‘定义SQL
    SQL = "--创建者：" & createBy & Ln
    SQL = SQL & "--创建时间：" & createDate & Ln
    SQL = SQL & "DROP TABLE IF EXISTS " & tableName & " ;" & Ln
    SQL = SQL & "CREATE TABLE " & tableName & "("
    ‘写入文件
    SqlFileDDL.WriteLine (SQL)
    For i = 3 To count_row_k
        If i = count_row_k Then
            col_name = TB & LCase(Cells(i, 2)) & " " & UCase(Cells(i, 4)) & " COMMENT ‘" & Trim(Cells(i, 3)) & "‘" & Ln & ")"
            SqlFileDDL.WriteLine(col_name)
            Exit For
        End If
        col_name = TB & LCase(Cells(i, 2)) & " " & UCase(Cells(i, 4)) & " COMMENT ‘" & Trim(Cells(i, 3)) & "‘,"
        SqlFileDDL.WriteLine(col_name)
    Next
    SqlFileDDL.WriteLine("COMMENT ‘" & tableComment & "‘")
