A Pass-through query allows you to execute a SQL statement directly against the tables in an external database (such as an Oracle, Sybase, or SQL Server database). This method uses your ODBC connection to directly access the data in the external database without having to link to the tables or import the data from the external database.
You could be wondering “Is there a better way to create a pass-through query in access?”
There has to be a better way ! Of course there is. Microsoft Access gives you the ability to issue the query created in Access directly against the SQL Server database, using T-SQL commands. This is called a Pass-Through Query in Microsoft Access. By the time you have finished reading this tip you will know precisely how to create one.
Another frequently asked question is “What is an access query?”.
An Access query is very versatile and can pull information from various tables and assemble it for display in a form or report. An Access query can either be a request for data results from your database or for action on the data, or for both.
It’s a construct in Microsoft Access that allows you to code the query text in the language of the back-end relational database management system – be it SQL Server, Oracle, or the like. The query is then passed back to the RDBMS in its native language for execution ; results being returned back to Access.
What is an update query in Microsoft Access?
