How to concatenate strings

Hello!

I'm working on a program that extracts data from one database to another.
In several places, some text fields have to be concatenated. For instance, There are 6 addresses lines to be stored into 3 lines. This example would be easy, but there are more complicated issues: 9 text lines have to be stored into 4 text fields.
I was thinking about a general stored procedure that could look like this:

ConcatenateFields @AllTheValues, @FieldNumber, @FieldLength, @result

This function should return the substring of @AllTheValues, starting at @FieldLength * @FieldNumber

The problem is that the @AllTheValues parameter could be a string > 255. Also, I thought of declaring as Text, but I'm not allowed to do so, like its not allowed to declare a local variable of type text.

Does anyone have an idea on how to implement such a function? How can I use large strings in a stored procedure? Any ideas?

Thanks.

the best way to handle this would be while extracting data at the first step - use OS string commands to get your results.

From Sybase 12.5 you can use bigger varchars... upto 16K if you set the pagesize (serversetting) high enough.
However if you would do this you may want to build a temporary 12.5 server which has 16K pages for this conversion, so you won't have to change any servers you use.

Even with a 2K page size, an ASE 12.5 server can have char/varchar columns up to ~1950 bytes in length.
