All Implemented Interfaces:
  `AutoCloseable`, `CallableStatement`, `PreparedStatement`, `Statement`, `Wrapper`, `TrackedUse`

public class PoolableCallableStatement extends DelegatingCallableStatement
A `DelegatingCallableStatement` that cooperates with `PoolingConnection` to implement a pool of `CallableStatement`s.

The `close()` method returns this statement to its containing pool. (See `PoolingConnection`.)

Since:
  2.0

- ## Constructor Details

  - ### PoolableCallableStatement

    public PoolableCallableStatement(CallableStatement callableStatement, PStmtKey key, KeyedObjectPool<PStmtKey,DelegatingPreparedStatement> pool, DelegatingConnection<Connection> connection)
    Constructor.
    Parameters:
      `callableStatement` - the underlying `CallableStatement`
      `key` - the key for this statement in the `KeyedObjectPool`
      `pool` - the `KeyedObjectPool` from which this CallableStatement was obtained
      `connection` - the `DelegatingConnection` that created this CallableStatement

- ## Method Details

  - ### close

    public void close() throws SQLException
    Returns the CallableStatement to the pool. If {`DelegatingStatement.isClosed()`, this is a No-op.
    Specified by:
      `close` in interface `AutoCloseable`
    Specified by:
      `close` in interface `Statement`
    Overrides:
      `close` in class `DelegatingStatement`
    Throws:
      `SQLException`

  - ### activate

    public void activate() throws SQLException
    Activates after retrieval from the pool. Adds a trace for this CallableStatement to the Connection that created it.
    Overrides:
      `activate` in class `DelegatingStatement`
    Throws:
      `SQLException` - thrown by the delegating statement.
    Since:
      2.4.0 made public, was protected in 2.3.0.

  - ### passivate

    public void passivate() throws SQLException
    Passivates to prepare for return to the pool. Removes the trace associated with this CallableStatement from the Connection that created it. Also closes any associated ResultSets.
    Overrides:
      `passivate` in class `DelegatingStatement`
    Throws:
      `SQLException` - thrown by the delegating statement.
    Since:
      2.4.0 made public, was protected in 2.3.0.
