Getting PSQLException while calling a Stored Procedure (which inserts record into lsa_user_info table) from Java method ( which is in DAO Layer)

问题

I am new to stored procedures. I want to insert a record with 20 column values into lsa_user_info table. I am invoking a stored procedure to do this task.

Also, I'm expecting the resultset will return the primary key value of the record that was inserted (user_id). But, I'm getting this error instead:

org.postgresql.util.PSQLException: **The column index is out of range: 20, number of columns: 19.

lsa_user_info table definition :

CREATE TABLE public.lsa_user_info

        user_id integer NOT NULL DEFAULT nextval('lsa_user_info_user_id_seq'::regclass),

Please let me know what is the issue? Why I am getting this error:

The column index is out of range: 20, number of columns: 19.

Please assist me! Thanks in advance

Changes in function: after inserting the data in table, the function should return the user_id of inserted row. you should change your Function as below

Change the return type from Numeric to Bigint
Change the name of parameters because table column names and parameter name are same.
Use returning statement with insert into to return the inserted user_id

Code:

CREATE OR REPLACE FUNCTION PUBLIC.insert_user_info (
        param_email_id CHARACTER VARYING,
        param_first_name CHARACTER VARYING,
        param_last_name CHARACTER VARYING,
        param_modified_user_id INTEGER,
        param_status_id INTEGER,

Changes in JAVA code: In Java code calling of Postgres function is different from stored procedure of MySQL or Oracle.
