[petar banicevic，修改在15 年前。]

Dears,

I need to invoke a store procedure. Anyone has code example for this?

Thx.

public static List getMyStoreProc(String key) throws SystemException{
Session session = null;
try {
//open a new session

session = HibernateUtil.openSession("&myHibernateSessionFactory");

//pull out our query from inference_custom.xml
//TODO fix the reason why its not loading from the xml file.
String sql = "{call myStoredProc(?)}";
//String sql = CustomSQLUtil.get(GET_USERS);
SQLQuery q = session.createSQLQuery(sql);


q.addScalar("mycolumn", Hibernate.STRING);

QueryPos qPos = QueryPos.getInstance(q);

qPos.add(key);

return QueryUtil.list(q, HibernateUtil.getDialect(), -1, -1);


}
catch (Exception e) {
throw new SystemException(e);
}
finally {
//must have this to close the hibernate session.. if you fail to do this.. you will have alot of open session..
HibernateUtil.closeSession(session);
}

}

I am writing stored procedures in liferay using custom queries. how can i call procedure in liferay? i tried in 2 ways
1). i tried to get query from xml file but getting null at " CustomSQLUtil.get("id") ". How can i use this custom query in my finder class?

2) Directly i called procedure in my finder class like
query = session.createSQLQuery("call myprocedure(?,?,?)");
This case its showing syntax error at "call".

How can i resolve this? Can any one please help me how to call procedures in liferay.?

Thanks & Regards
Gouse Mohiddin. M

Hi
Use escape character try as follows

String sql ="call FeedBack_FeedBackSearch(?\,?\,?\,?\,?\,?)\;";

Hi,

Thanx for your reply, It's working fine, But after calling SP, How can i execute? query.executeUpdate() is not working For SP.

static final String GET_USER_DATA =CommentFinderImpl.class.getName()+".insertComment";
Session session = null;
SQLQuery query = null;
try {
session = openSession();
String sql = CustomSQLUtil.get(GET_USER_DATA);
query = session.createSQLQuery(sql);
QueryPos pos=QueryPos.getInstance(query);
pos.add(description);
pos.add(parentid);
pos.add(eventid);
pos.add(userid);
query.executeUpdate();
Here I have used query.executeUpdate(), but its throwing error,
