Constructor Detail

### JDBC4DatabaseMetaDataUsingInfoSchema

    public JDBC4DatabaseMetaDataUsingInfoSchema(ConnectionImpl connToSet,
                                                java.lang.String databaseToSet)
                                         throws java.sql.SQLException

Throws:
  `java.sql.SQLException`

Method Detail

### getRowIdLifetime

    public java.sql.RowIdLifetime getRowIdLifetime()
                                            throws java.sql.SQLException

  Throws:
    `java.sql.SQLException`

### isWrapperFor

    public boolean isWrapperFor(java.lang.Class<?> iface)
                         throws java.sql.SQLException

  Returns true if this either implements the interface argument or is directly or indirectly a wrapper for an object that does. Returns false otherwise. If this implements the interface then return true, else if this is a wrapper then return the result of recursively calling `isWrapperFor` on the wrapped object. If this does not implement the interface and is not a wrapper, return false. This method should be implemented as a low-cost operation compared to `unwrap` so that callers can use this method to avoid expensive `unwrap` calls that may fail. If this method returns true then calling `unwrap` with the same argument should succeed.

  Parameters:
    `interfaces` - a Class defining an interface.
  Returns:
    true if this implements the interface or directly or indirectly wraps an object that does.
  Throws:
    `java.sql.SQLException` - if an error occurs while determining whether this is a wrapper for an object with the given interface.
  Since:
    1.6

### unwrap

    public <T> T unwrap(java.lang.Class<T> iface)
             throws java.sql.SQLException

  Returns an object that implements the given interface to allow access to non-standard methods, or standard methods not exposed by the proxy. The result may be either the object found to implement the interface or a proxy for that object. If the receiver implements the interface then that is the object. If the receiver is a wrapper and the wrapped object implements the interface then that is the object. Otherwise the object is the result of calling `unwrap` recursively on the wrapped object. If the receiver is not a wrapper and does not implement the interface, then an `SQLException` is thrown.

  Parameters:
    `iface` - A Class defining an interface that the result must implement.
  Returns:
    an object that implements the interface. May be a proxy for the actual implementing object.
  Throws:
    `java.sql.SQLException` - If no object found that implements the interface
  Since:
    1.6

### getJDBC4FunctionNoTableConstant

    protected int getJDBC4FunctionNoTableConstant()

  Overrides:
    `getJDBC4FunctionNoTableConstant` in class `DatabaseMetaData`
