Count Unicode characters in DB2 8

Hi,

I am looking for a function (or hint) how I can count unicode
characters (and not bytes) in DB2 V8.2.
In DB2 9 the length function is extenced with the codeunits32 option -
and this is exactly what I need in DB2 V8.2.

Can anybody help me with that?

Thanks in advance
kind regards
Michael

I would write a simple Java UDF that takes the string as input and counts
the number of characters. Something like this (completely untested) should
do:

import java.lang.*; // for String class
import COM.ibm.db2.app .UDF; // UDF classes

public class UnicodeCharCoun t extends UDF
{
public void charCount(Strin g str, int count) throws Exception
{
if (str != null) {
set(2, str.length());
}
}
}

Hi!

Maybe something in the lines of:
VALUES(LENGTH(V ARGRAPHIC('YOUR _UNICODE_STRING ')))

Best regards,
Kovi

Hi Kovi,

thanks that is what I need.
I tried it before but somehow got an error - something like
incompatible datatypes for the function...
Now I tried it again after you posted that solution and it works!

Thanks again
kindregards
Michael
