How Can I Run SQL Queries on Dynamically Named Excel Ranges Without Hardcoding?

Execute SQL queries on Excel sheets without hardcoding ranges

In Microsoft Excel, executing SQL queries on data in tables in a workbook is often an ideal method for efficient data retrieval and manipulation. However, hardcoding the range address in the query limits its flexibility and applicability. This article addresses the challenges faced by users looking to use SQL queries on dynamic named ranges or Excel table names.

The following VBA code demonstrates how to dynamically obtain a range address and merge it into a SQL statement:

<code class="language-vba">Sub SQLQueryDynamic()

    ' 将命名范围地址定义为变量
    Dim rngAddress As String

    ' 将活动命名范围地址转换为单个字符串
    rngAddress = ActiveWorkbook.Names.Item("namedRangeName").RefersToLocal

    ' 使用动态范围地址构造SQL字符串
    Dim strSQL As String
    strSQL = "SELECT * FROM [" & rngAddress & "]"

    ' 打开ADODB连接和记录集
    Dim cn As ADODB.Connection, rs As ADODB.Recordset
    Set cn = CreateObject("ADODB.Connection")
    Set rs = CreateObject("ADODB.Recordset")

    strFile = ThisWorkbook.FullName
    strCon = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & _
    strFile & ";Extended Properties=""Excel 12.0;HDR=Yes;IMEX=1"";"

    cn.Open strCon

    ' 执行SQL查询
    rs.Open strSQL, cn

    ' 打印结果
    Debug.Print rs.GetString

    ' 清理
    rs.Close
    cn.Close
End Sub</code>

This code enables users to define dynamic named ranges or use Excel table names and execute SQL queries without hard coding. Additionally, it eliminates the need to rely on knowing the table name where the table or named range resides. By using this approach, VBA developers can provide Excel users with greater flexibility and data retrieval capabilities.
