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)

When you execute the SQLRetrieve command with the argument "NamedRngLogical" set to TRUE, the column names in the result set will always be defined on the active workbook regardless of what the "DestinationRef" argument is set to. If no workbooks are active when you run the SQLRetrieve command, and if "NamedRngLogical" is set to TRUE, you will receive the #N/A error value; however, the records will still be retrieved to the range specified by destination.

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

Note also that an underscore character (_) indicates that code continues from one line to the next. You can type lines that contain this character as one logical line or you can divide the lines of code and include the line continuation character.

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

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

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

To run the example, follow these steps:

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

Switch to a worksheet.

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