public boolean execute(String sql,
                       int autoGeneratedKeys)
                throws SQLException
```
    Executes the given SQL statement, which may return multiple results, and signals the driver that any auto-generated keys should be made available for retrieval. The driver will ignore this signal if the SQL statement is not an INSERT statement, or an SQL statement able to return auto-generated keys (the list of such statements is vendor-specific).
    
    In some (uncommon) situations, a single SQL statement may return multiple result sets and/or update counts. Normally you can ignore this unless you are (1) executing a stored procedure that you know may return multiple results or (2) you are dynamically executing an unknown SQL string.
    The execute method executes an SQL statement and indicates the form of the first result. You must then use the methods getResultSet or getUpdateCount to retrieve the result, and getInternalMoreResults to move to any subsequent result(s).
    
    Specified by:
    
    execute in interface Statement
    
    Parameters:
    
    sql - any SQL statement
    
    autoGeneratedKeys - a constant indicating whether auto-generated keys should be made available for retrieval using the methodgetGeneratedKeys; one of the following constants: Statement.RETURN_GENERATED_KEYS or Statement.NO_GENERATED_KEYS
    
    Returns:
    
    true if the first result is a ResultSet object; false if it is an update count or there are no results
    
    Throws:
    
    SQLException - if a database access error occurs, this method is called on a closed Statement or the second parameter supplied to this method is not Statement.RETURN_GENERATED_KEYS or Statement.NO_GENERATED_KEYS.

    Releases this Statement object's database and JDBC resources immediately instead of waiting for this to happen when it is automatically closed. It is generally good practice to release resources as soon as you are finished with them to avoid tying up database resources. Calling the method close on a Statement object that is already closed has no effect. Note:When a Statement object is closed, its current ResultSet object, if one exists, is also closed.

  - getMaxFieldSize
```
public int getMaxFieldSize()
```
    Retrieves the maximum number of bytes that can be returned for character and binary column values in a ResultSet object produced by this Statement object. This limit applies only to BINARY, VARBINARY, LONGVARBINARY, CHAR, VARCHAR, NCHAR, NVARCHAR, LONGNVARCHAR and LONGVARCHAR columns. If the limit is exceeded, the excess data is silently discarded.
    
    Specified by:
    
    getMaxFieldSize in interface Statement
    
    Returns:
    
    the current column size limit for columns storing character and binary values; zero means there is no limit

    SQLException - if the condition max >= 0 is not satisfied
  - setEscapeProcessing
```
public void setEscapeProcessing(boolean enable)
```
    Sets escape processing on or off. If escape scanning is on (the default), the driver will do escape substitution before sending the SQL statement to the database. Note: Since prepared statements have usually been parsed prior to making this call, disabling escape processing for PreparedStatements objects will have no effect.
    
    Specified by:
    
    setEscapeProcessing in interface Statement
    
    Parameters:
    
    enable - true to enable escape processing; false to disable it

    Specified by:
    
    setQueryTimeout in interface Statement
    
    Parameters:
    
    seconds - the new query timeout limit in seconds; zero means there is no limit

    Parameters:
    
    inputStream - inputStream instance, that will be used to send data to server
    
    Throws:
    
    SQLException - if statement is closed
  - cancel
```
public void cancel()
            throws SQLException
```
    Cancels this Statement object if both the DBMS and driver support aborting an SQL statement. This method can be used by one thread to cancel a statement that is being executed by another thread.
    In case there is result-set from this Statement that are still streaming data from server, will cancel streaming.
    
    Specified by:
    
    cancel in interface Statement
    
    Throws:
    
    SQLException - if a database access error occurs or this method is called on a closed Statement
  - getWarnings
```
public SQLWarning getWarnings()
                       throws SQLException
```
    Retrieves the first warning reported by calls on this Statement object. Subsequent Statement object warnings will be chained to this SQLWarning object.
    The warning chain is automatically cleared each time a statement is (re)executed. This method may not be called on a closed Statement object; doing so will cause an SQLException to be thrown.
    
    Note: If you are processing a ResultSet object, any warnings associated with reads on that ResultSet object will be chained on it rather than on the Statement object that produced it.
    
    Specified by:
    
    getWarnings in interface Statement
    
    Returns:
    
    the first SQLWarning object or null if there are no warnings
    
    Throws:
    
    SQLException - if a database access error occurs or this method is called on a closed Statement
  - clearWarnings
```
public void clearWarnings()
```
    Clears all the warnings reported on this Statement object. After a call to this method, the method getWarnings will return null until a new warning is reported for this Statement object.
    
    Specified by:
    
    clearWarnings in interface Statement
  - setCursorName
```
public void setCursorName(String name)
                   throws SQLException
```
    Sets the SQL cursor name to the given String, which will be used by subsequent Statement object execute methods. This name can then be used in SQL positioned update or delete statements to identify the current row in the ResultSet object generated by this statement. If the database does not support positioned update/delete, this method is a noop. To insure that a cursor has the proper isolation level to support updates, the cursor's SELECT statement should have the form SELECT FOR UPDATE. If FOR UPDATE is not present, positioned updates may fail.
    Note: By definition, the execution of positioned updates and deletes must be done by a different Statement object than the one that generated the ResultSet object being used for positioning. Also, cursor names must be unique within a connection.
    
    Specified by:
    
    setCursorName in interface Statement
    
    Parameters:
    
    name - the new cursor name, which must be unique within a connection
    
    Throws:
    
    SQLException - if a database access error occurs or this method is called on a closed Statement

public ResultSet getGeneratedKeys()
                           throws SQLException
```
    Retrieves any auto-generated keys created as a result of executing this Statement object. If this Statement object did not generate any keys, an empty ResultSet object is returned.
    Note:If the columns which represent the auto-generated keys were not specified, the JDBC driver implementation will determine the columns which best represent the auto-generated keys.
    
    Specified by:
    
    getGeneratedKeys in interface Statement
    
    Returns:
    
    a ResultSet object containing the auto-generated key(s) generated by the execution of this Statement object

    SQLException - if a database access error occurs or this method is called on a closed Statement
  - getResultSetHoldability
```
public int getResultSetHoldability()
```
    Retrieves the result set holdability for ResultSet objects generated by this Statement object.
    
    Specified by:
    
    getResultSetHoldability in interface Statement
    
    Returns:
    
    either ResultSet.HOLD_CURSORS_OVER_COMMIT or ResultSet.CLOSE_CURSORS_AT_COMMIT
    
    Since:
    
    1.4
  - isClosed
```
public boolean isClosed()
```
    Retrieves whether this Statement object has been closed. A Statement is closed if the method close has been called on it, or if it is automatically closed.
    
    Specified by:
    
    isClosed in interface Statement
    
    Returns:
    
    true if this Statement object is closed; false if it is still open

    setPoolable(boolean)
  - setPoolable
```
public void setPoolable(boolean poolable)
```
    Requests that a Statement be pooled or not pooled. The value specified is a hint to the statement pool implementation indicating whether the applicaiton wants the statement to be pooled. It is up to the statement pool manager as to whether the hint is used.
    
    The poolable value of a statement is applicable to both internal statement caches implemented by the driver and external statement caches implemented by application servers and other applications.
    
    By default, a Statement is not poolable when created, and a PreparedStatement and CallableStatement are poolable when created.
    
    Specified by:
    
    setPoolable in interface Statement
    
    Parameters:
    
    poolable - requests that the statement be pooled if true and that the statement not be pooled if false

  - unwrap
```
public <T> T unwrap(Class<T> iface)
             throws SQLException
```
    Returns an object that implements the given interface to allow access to non-standard methods, or standard methods not exposed by the proxy.
    
    If the receiver implements the interface then the result is the receiver or a proxy for the receiver. If the receiver is a wrapper and the wrapped object implements the interface then the result is the wrapped object or a proxy for the wrapped object. Otherwise return the the result of calling unwrap recursively on the wrapped object or a proxy for that result. If the receiver is not a wrapper and does not implement the interface, then an SQLException is thrown.
    
    Specified by:
    
    unwrap in interface Wrapper
    
    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:
    
    SQLException - If no object found that implements the interface

  - isWrapperFor
```
public boolean isWrapperFor(Class<?> interfaceOrWrapper)
                     throws 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.
    
    Specified by:
    
    isWrapperFor in interface Wrapper
    
    Parameters:
    
    interfaceOrWrapper - a Class defining an interface.
