What is the default size of a varchar2 input to Oracle stored procedure, and can it be changed?
oracle, stored-procedures, varchar2
Solution
You cannot specify a size for a VARCHAR2 parameter to a procedure.
The procedure should happily accept strings up to 32k in size (the maximum size of a VARCHAR2 in PL/SQL). If it were a function that was being called from SQL rather than PL/SQL, the limit would be 4k because the maximum size of a VARCHAR2 in SQL is only 4k.
Problem
I have a stored procedure in Oracle Database 10g where my input is a varchar2 but I'm having issues getting it to run when the input string is long (not sure of exact length maybe > 8000). My thought is the 'intext varchar2' (as below) is by default is too small. In other cases where I need a longer string I might define a varchar2 as "intext2 VARCHAR2(32767);" I tried to define the size similarly in the code below but my syntax is incorrect. ``` create or replace PROCEDURE TESTPROC ( intext IN VARCHAR2 ) AS .... ``` What is the (default) size of the intext varchar2? Can that size be defined (increased)?
