XL: SQLRetrieve Defines Field Names on Active Workbook

• Microsoft Excel for Windows, versions 5.0, 5.0c
• Microsoft Excel for Windows 95, version 7.0
• Microsoft Excel for the Macintosh, versions 5.0, 5.0a

SUMMARY

In Microsoft Excel, if you are using the Visual Basic, Applications Edition SQLRetrieve command, and you want each column of results to be declared as a named range on the worksheet, you can set the "NamedRngLogical" argument to TRUE.

The name of each range is the field name of a column's result set. The syntax for the SQLRetrieve statement is as follows:

   SQLRetrieve(ConnectionNum, DestinationRef, MaxColumns, MaxRows,
     ColNamesLogical, RowNumsLogical, NamedRngLogical,
     FetchFirstLogical)

NOTE: The information in this article also applies to the Microsoft Excel 4.0 command SQL.EXEC.QUERY.

The following sample Visual Basic code uses the CUSTOMER.DBF file included with the sample data source NWind and assumes that:

1. The NWind ODBC driver is installed and points to the Windows or a shared MSAPPS\MSQUERY directory.

2. The module sheet has references to XLODBC.XLA found in the EXCEL\LIBRARY\MSQUERY directory, under the TOOLS-REFERENCES menu.

1. In a new module sheet, enter in the following code:

         Sub GetData()
   
            ' To define the ranges for the column names in the workbook to 
            ' which the data is returned, use the following macro:
   
            Dim DestRange As Object
            Dim Chan, NumCols, NumRows As Variant
            Dim i As Integer
   
            Set DestRange = ThisWorkbook.Sheets("Sheet1").Range("A1")
   
            Chan = SQLOpen("DSN=NWind;FIL=dBase4;")
   
            ' Enter the following statement on a single line.
            NumCols = SQLExecQuery(Chan, "SELECT customer.CONTACT, " & _
              "customer.COMPANY FROM customer.dbf")
   
            NumRows = SQLRetrieve(Chan, DestRange, , , True)
   
            SQLClose(Chan)
   
            DestRange.Resize(NumRows + 1, NumCols).CreateNames Top:=True, _
               Left:=False
   
         End Sub
   
   

2. Switch to a worksheet.

3. From the Tools menu, choose Macros, and then select the GetData macro.
