Methods in java.sql that return Ref
Modifier and Type	Method	Description
`Ref`	CallableStatement.`getRef(int parameterIndex)`	Retrieves the value of the designated JDBC `REF(<structured-type>)` parameter as a `Ref` object in the Java programming language.
`Ref`	CallableStatement.`getRef(String parameterName)`	Retrieves the value of a JDBC `REF(<structured-type>)` parameter as a `Ref` object in the Java programming language.
`Ref`	ResultSet.`getRef(int columnIndex)`	Retrieves the value of the designated column in the current row of this `ResultSet` object as a `Ref` object in the Java programming language.
`Ref`	ResultSet.`getRef(String columnLabel)`	Retrieves the value of the designated column in the current row of this `ResultSet` object as a `Ref` object in the Java programming language.
