Fuzzy Lookup Transformation Editor (Reference Table Tab)

Updated: 5 December 2005

Use the Reference Table tab of the Fuzzy Lookup Transformation Editor dialog box to specify the source table and the index to use for the lookup.

ms181193.note(en-US,SQL.90).gifNote:
The Fuzzy Lookup transformation creates a working copy of the reference table. The indexes described below are created on this working table by using a special table, not an ordinary SQL Server index. The transformation does not modify the existing source tables unless you select Maintain stored index. In this case, it creates a trigger on the reference table that updates the working table and the lookup index table based on changes to the reference table.

ms181193.note(en-US,SQL.90).gifNote:
The Exhaustive and the MaxMemoryUsage properties of the Fuzzy Lookup transformation are not available in the Fuzzy Lookup Transformation Editor, but can be set by using the Advanced Editor. In addition, a value greater than 100 for MaxOutputMatchesPerInput can be specified only in the Advanced Editor. For more information on these properties, see the Fuzzy Lookup Transformation section of Transformation Custom Properties.

To learn more about the Fuzzy Lookup transformation, see Fuzzy Lookup Transformation.
