Temporary Table Implementation

Temporary Table Implementation

You can store intermediate query result set data in temporary tables when complex queries produce large amounts of intermediate data. For example, temporary tables can store frequently used join results. Business intelligence tools can query the temporary table instead of the SQL data service, resulting in increased performance.
To implement temporary tables, the Informatica administrator and the business intelligence tool user perform the following separate tasks:
Step 1. The Informatica administrator creates a connection for the data integration service.
In the Administrator tool, create a connection to the SQL data service. Edit the
SQL Properties
of the Data Integration Service and select a relational database connection for the
Table Storage Connection
property. Recycle the Data Information Service.
Step 2. The business intelligence tool user creates a connection for the SQL data service.
In a business intelligence tool, create a connection to the SQL data service. The connection uses the Informatica ODBC or JDBC driver.
Step 3. Queries from the business intelligence tool create and use temporary tables.
While the connection is active, the business intelligence tool issues queries to the SQL data service. These queries create and use temporary tables to store large amounts of data that the complex query produces. When the connection ends, the database drops the temporary table.
