Subj:   Re: Varbyte Conversion
 
From:   Geoffrey Rommel

  has anyone converted a hex value into a varbyte ?  


The manuals say that BYTE and VARBYTE cannot be converted to or from any other data type. You would therefore have to use either a UDF (I believe this is one of the reasons UDF's were provided) or dynamic SQL.

In a stored procedure, the dynamic SQL would be something like this (UNTESTED):

     declare big_string varchar(64000) character set unicode;
     declare big_sql varchar(64000) character set unicode;

     select char2hexint(char_column) ... into :big_string;
     set big_sql = 'insert into target_tbl (''' || big_string || '''xbv)';
     call DBC.SysExecSql(:big_sql);

Messy, isn't it? I like UDF's better.
