Server driver optional feature not implemented

Append dbCommand. In order to determine the number, names, types, and sizes of parameters needed in a stored procedure, use the Parameters. Refresh method of the command object.

You can call this method during development of your application to determine the correct requirements for the stored procedure, then remove the expensive call to Parameters.

If the field indicates that an error has occurred, fields in the diagnostic data structure will indicate the row and parameter number of the parameter that failed. For more information about ignoring parameters, see the next section, "Ignoring a Set of Parameters. For each element in this array, the diagnostic data structure contains one or more status records.

Some errors in the processing of a single set of parameters cause processing of the subsequent sets of parameters in the array to stop. Other errors do not affect the processing of subsequent parameters. Which errors will stop processing is driver-defined. In ODBC 2. The buffer pointed to by the pirow argument of SQLParamOptions contained the number of the error row.

In ODBC 3. This change in behavior may cause problems for existing applications. When an array of parameters is sent to a SELECT statement, the availability of status array values is driver-defined; they may be available after the statement has been executed or as result sets are fetched. To direct the driver to ignore one or more sets of parameters during execution, an application should follow these steps:.

This is useful when binding parameters to row data. Parameters can then be ignored according to the status of the row data. The driver overwrites the old binding with the new one. Specify an offset to be added to the buffer address that was specified by the binding call to SQLBindParameter.

For more information, see the next section, "Rebinding with Offsets. Rebinding of parameters is especially useful when an application has a buffer area setup that can contain many parameters but a call to SQLExecDirect or SQLExecute uses only a few of the parameters.

The remaining space in the buffer area can be used for the next set of parameters by modifying the existing binding by an offset. The new pointer values are used when the SQL statements are executed. The offset remains valid after rebinding. The pointer is set to null by default.

If the offset is changed to a different value, the new value is still added directly to the value in each descriptor field. The new offset is not added to the sum of the field value and any earlier offsets. This occurs when the ARD associated with the statement is explicitly allocated and is also associated with other statements.

If this is not the required behavior, the application should dissociate this descriptor from the other statements before it calls SQLBindParameter. For each row of data, the application assigns data values to each parameter and calls SQLExecute to execute the statement.

The following sample assumes that you have an ODBC data source on your computer called Northwind that is associated with the Northwind database. In the following example, an application executes a SQL Server stored procedure using a named parameter.

Skip to main content. This browser is no longer supported. To diagnose, we usually need to know the following, including version numbers. On Windows, be sure to specify bit Python or bit:. Often it is easiest to describe your issue as "expected behavior" and "observed behavior". The text was updated successfully, but these errors were encountered:. The SQL Server driver is very old and does not support features of newer servers. Sorry, something went wrong.

I don't think this is the best answer because you are changing your database types when all you need to do is use the correct driver see accepted answer — Rob Sedgwick.
