Text Extender provides user-defined functions (UDFs) to search in text documents stored in DB2 UDB , and to work with the results of a search. Some of the UDFs' parameters are data types known as user-defined distinct types (UDTs) that are provided with Text Extender.
This chapter describes the UDTs and the UDFs.
Text Extender provides a DB2 UDB command line processor input file called txsample.udf. It contains examples of Text Extender UDFs that run against the sample tables described in The sample table DB2TX.SAMPLE. Use this file to see examples of the syntax of the administration and search UDFs.
