* Revision 1.2 2000/11/28 06:47:52 fsg
* Changed declaration of ascii_char in ib_udf.sql
* to get correct result as proposed by Claudio Valderrama
* 2001.5.19 Claudio Valderrama, add the declaration of alternative
* substrlen function to handle string,start,length instead.
* 2004.9.1 Claudio Valderrama, changed some UDF's to be able to detect NULL
* and renamed the resulting file as ib_udf2.sql.
