Unable to create user-defined function in C++

can you post your code?

@skeswani Please find an attached text file

the problem I think is here

returnType.addVarchar(t.getStringLength());

this result in the copy of a buf which is 20 bytes into a response that is 7 bytes

resWriter.getStringRef().copy(buf);

change this to

returnType.addVarchar(20) ;

note, putting s '>' sign before the line will help format the code correctly in the forums

20 or more, this is the output return type for the scalar function. basically the scalar function return varchar(20) in this case. but maybe you want to make it varchar(32) for good measure

@skeswani Thanks its work.
