How to pass an empty string to a Date type column through hibernate
If your inserting data to your database and the database allows
null
values for that column just don't set that parameter in your query. In this case it's automatically set tonull
.If your having an update statement and want to set an existing value to
null
you could try something like that:query.setParameter(3, PreparedStatement.setNull());
Hope that helps!
EDIT:
String updq2; bool isNull = false; //If your data is null and you want to set it null use this if(yourDate == null) { updq2 = "update TblUser a set loggedStatus = ? ,lockedStatus= ?,currentAttempts = ?,logoutDate = NULL where upper(a.id)=?";//,lockedStatus= ?, currentAttempts = ?, logoutDate = ? where upper(a.id) = ?"; isNull = true; } //If it isn't null and you want to set and value use this else { updq2 = "update TblUser a set loggedStatus = ? ,lockedStatus= ?,currentAttempts = ?,logoutDate = ? where upper(a.id)=?";//,lockedStatus= ?, currentAttempts = ?, logoutDate = ? where upper(a.id) = ?"; } Session newSession2=factory.openSession(); Transaction tx1=newSession2.beginTransaction(); Query query =newSession2.createQuery(updq2); query.setParameter(0, (byte)9); query.setParameter(1,"1" ); query.setParameter(2, 0); if(isNull) { query.setParameter(3, userName.toUpperCase()); } else { query.setParameter(3, yourDataHere); query.setParameter(4, userName.toUpperCase()); }
