Transform Data Task Properties (Lookups Tab)
Use this tab to define a lookup query. Before defining a lookup query, you must first create connections for the source, binding, and lookup tables, and specify the source and binding tables.
Type a name for the lookup.
Choose an existing connection from the list on which to execute the lookup query.
Type a value for or view the number of lookup results saved in a cache. Caching is especially useful with lookups if the number of rows being transformed is large, and you are querying on a small number of rows in the lookup table.
Build the lookup query in the Data Transformation Services (DTS) Query Designer. You can also paste the query from a text editor into the SQL pane.
Create a new lookup query, which will be listed as a row in the Lookups table.
Removes the highlighted lookup query from the Lookups table.
