## Uses of Interface
java.sql.Ref

Packages that use Ref
java.sql: Provides the API for accessing and processing data stored in a data source (usually a relational database) using the JavaTM programming language.
javax.sql: Provides the API for server side data source access and processing from the JavaTM programming language.
javax.sql.rowset: Standard interfaces and base classes for JDBC `RowSet` implementations.
javax.sql.rowset.serial: Provides utility classes to allow serializable mappings between SQL types and data types in the Java programming language.

### Uses of Ref in java.sql

Methods in java.sql that return Ref
`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` 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` 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.
`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` SQLInput.`readRef()` Reads an SQL `REF` value from the stream and returns it as a `Ref` object in the Java programming language.

Methods in java.sql with parameters of type Ref
`void` PreparedStatement.`setRef(int parameterIndex, Ref x)` Sets the designated parameter to the given `REF(<structured-type>)` value.
`void` ResultSet.`updateRef(int columnIndex, Ref x)` Updates the designated column with a `java.sql.Ref` value.
`void` ResultSet.`updateRef(String columnLabel, Ref x)` Updates the designated column with a `java.sql.Ref` value.
`void` SQLOutput.`writeRef(Ref x)` Writes an SQL `REF` value to the stream.

### Uses of Ref in javax.sql

Methods in javax.sql with parameters of type Ref
`void` RowSet.`setRef(int i, Ref x)` Sets the designated parameter in this `RowSet` object's command with the given `Ref` value.

### Uses of Ref in javax.sql.rowset

Methods in javax.sql.rowset with parameters of type Ref
`void` BaseRowSet.`setRef(int parameterIndex, Ref ref)` Sets the designated parameter to the given `Ref` object in the Java programming language.

### Uses of Ref in javax.sql.rowset.serial

Classes in javax.sql.rowset.serial that implement Ref
`class` `SerialRef` A serialized mapping of a `Ref` object, which is the mapping in the Java programming language of an SQL `REF` value.

Methods in javax.sql.rowset.serial that return Ref
`Ref` SQLInputImpl.`readRef()` Retrieves the value at the head of this `SQLInputImpl` object as a `Ref` object in the Java programming language.

Methods in javax.sql.rowset.serial with parameters of type Ref
`void` SQLOutputImpl.`writeRef(Ref x)` Writes a `Ref` object in the Java programming language to this `SQLOutputImpl` object.

Constructors in javax.sql.rowset.serial with parameters of type Ref
Constructor and Description
`SerialRef(Ref ref)` Constructs a `SerialRef` object from the given `Ref` object.
