                    throws HibernateException,
                           SQLException

Deprecated.

Get a column value from a result set, without worrying about the possibility of null values. Called from nullSafeGet(java.sql.ResultSet, java.lang.String[], org.hibernate.engine.SessionImplementor, java.lang.Object) after nullness checks have been performed.

Parameters:

rs - The result set from which to extract the value.

name - The name of the value to extract.

Returns:

The extracted value.

Throws:

HibernateException - Generally some form of mismatch error.

SQLException - Indicates problem making the JDBC call(s).

set

public abstract void set(PreparedStatement st,
                         Object value,
                         int index)
                  throws HibernateException,
                         SQLException

Deprecated.

Set a parameter value without worrying about the possibility of null values. Called from nullSafeSet(java.sql.PreparedStatement, java.lang.Object, int, boolean[], org.hibernate.engine.SessionImplementor) after nullness checks have been performed.

Parameters:

st - The statement into which to bind the parameter value.

value - The parameter value to bind.

Throws:

HibernateException - Generally some form of mismatch error.

SQLException - Indicates problem making the JDBC call(s).

sqlType
