The output of LISTAGG is either 4000 Byte (if the column in a Character
Column) or 1 MB if the column is a Large Object (LOB).
If you want the output shorter or any other length, just CAST the Result to
either CHAR/VARCHAR or Large Object and specify the maximum length.

Subject: Limiting size limits for LISTAGG function
Greetings fellow humans
I've checked around but can't find an answer to this.
How can you do a limit to the size of a LISTAGG result, say, to a column
width of 48?
I ran an SQL (complex) statement given to me to use to generate a output
file that will feed to a spreadsheet report. The SQL generates a database
file but one of the columns is LISTAGG(REFERENCE, ', ') WUTHIN GROUP (ODER
BY REFERENCE) AS MASTER_BOL but it generates a fixed column size of 4000.
Can I wrap all that inside a maximum size, truncated if necessary?
