Exception while calling stored procedure from jdbc - mysql

Question

Calling a stored procedure results in this exception:
SQLException1 java.sql.SQLException: User does not have access to
metadata required to determine stored procedure parameter types. If
rights can not be granted, configure connection with
"noAccessToProcedureBodies=true" to have driver generate parameters
that represent INOUT strings irregardless of actual parameter types.
To resolve this, I tried:
Connection c = DriverManager.getConnection("jdbc:mysql://localhost:3306
/database?useInformationSchema=true&noAccessToProcedureBodies=true",
"user_name", "pasword");
But it still does not work.
I am using shared hosting.
I am using
Software version: 5.0.91-community-log - MySQL Community Edition (GPL)
Protocol version: 10
Java 1.6
mysql-connector-java-5.1.14-bin.jar
One of my stored procedures is:
DROP PROCEDURE IF EXISTS `share_message`
DELIMITER //
CREATE PROCEDURE share_message(in messageid1 int(200),in received_by1 int(20),
in sent_by1 int(20),in shared_of1 int(20),author1 int(20), OUT query_status1 TINYINT)
BEGIN
DECLARE EXIT HANDLER FOR SQLEXCEPTION
BEGIN
-- ERROR
SET query_status1 = -1;
rollback;
END;
DECLARE EXIT HANDLER FOR SQLWARNING
BEGIN
-- WARNING
SET query_status1 = -1;
rollback;
END;
START TRANSACTION;
SET query_status1 = 0;
INSERT INTO post_message_users(messageid,received_by,sent_by,shared_of,author)
VALUES(messageid1,received_by1,sent_by1,shared_of1,author1);
UPDATE post_messages SET total_share=total_share+1 WHERE messageid=messageid1;
SET query_status1 =1;
COMMIT;
END//
DELIMITER ;
This is working properly with my local database.

Answer 1

It seems that the stored procedure you are attempting to use needs access to MySQL's INFORMATION_SCHEMA. That's a (fake) database built in every MySQL server; it's used to fetch descriptions of tables, columns, indexes, and the like.
It looks like the user id you're using doesn't have access to the INFORMATION_SCHEMA. That's understandable on a hosting service.
Go on MyPhpAdmin and try a query like this to be sure about that.
SELECT table_schema, table_name
FROM information_schema.columns
WHERE column_name = 'something'
AND table_schema = 'your database name'
If you get some kind of error saying you don't have permission, this is definitely your problem.
You could try rewriting your stored proc, or you could ask your hosting service to grant you the appropriate priv.

TLDR; Change your Java code, make the CallableStatement reference parameters by index instead of name.
After having a similar problem I updated my JDBC driver mysql-connector-java-5.1.26-bin.jar.
The error then changed from
User does not have access to metadata required to determine stored
procedure parameter types. If rights can not be granted, configure
connection with "noAccessToProcedureBodies=true" to have driver
generate parameters that represent INOUT strings irregardless of
actual parameter types.
to
No access to parameters by name when connection has been configured not to access procedure bodies
I changed my Callable Statement to reference parameters by index instead of name, and hey presto it works.
Updating the driver may not be necessary, just knowing to use indexes instead of names when you don't have metadata access or routine body access.
Good Luck
