Getting ORA-06502 or ORA-01461 When Calling Stored Procedure That Has a CHAR OUT Parameter From JDBC (Doc ID 1300792.1)

Last updated on AUGUST 09, 2023

Applies to:

JDBC - Version 11.2.0.2.0 and later
Information in this document applies to any platform. *** *** ( retested using database and JDBC driver version 12.1.0.2)

Symptoms

A simple JDBC standalone testcase gets ORA-06502 PL/SQL: numeric or value error: character string buffer too small (when database parameter blank_trimming=false) or ORA-01461: can bind a LONG value only for insert into a LONG column (when database parameter blank_trimming=true).
The error is triggered by a CallableStatement executing a PL/SQL stored procedure that has an argument of CHAR(10) defined through a %TYPE which is based on a database table column.
