Instead, it submits multiple queries, often including queries that request all of the rows in a table, and then it combines or filters the data on the client.If the criteria require local processing, even queries that should return only selected rows from a single table can require that all the rows in the table be returned.Suppliers, and that explicitly names the three columns in the table. In the first step, Office Access picks a "bookmark" column or set of columns, which is usually the table's primary key but could be based on any unique index, and retrieves just those values for every row in the table or query. Then Office Access prepares a parameterized SQL statement to select all the columns in the table or query for 10 rows at a time.Instead, both the file and the SQL Profiler trace show that three statements are executed. SQLExec Direct: SELECT "dbo"."Shippers"."Shipper ID" FROM "dbo"."Shippers" SQLPrepare: SELECT "Shipper ID","Company Name","Phone" FROM "dbo"."Shippers" WHERE "Shipper ID" = ? The final step is to execute this statement, which is assigned a number on the server (6 in the example), as many times as needed, passing in 10 bookmark values at a time.

The most common way this is done is by creating linked tables in Office Access that use the SQL Server ODBC driver to connect to tables in SQL Server databases.The SQL Server Migration Assistant (SSMA) for Office Access enables you to convert an Office Access database to this type of application by moving your Office Access data to new SQL Server tables and linking to these tables.Any forms, reports, queries, or code that previously worked with the original Office Access tables are automatically connected to the new SQL Server tables.Select a template that shows TSQL to see all the statements being processed by the server.From the client side, you can edit a Microsoft Windows registry setting that allows you to see the commands that the Office Access database engine is submitting to ODBC.
