  - setCursorName
```
public void setCursorName(String name)
                   throws SQLException
```
    Description copied from interface: java.sql.Statement
    
    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

  - setEscapeProcessing
```
public void setEscapeProcessing(boolean enable)
                         throws SQLException
```
    Description copied from interface: java.sql.Statement
    
    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.
    The Connection and DataSource property escapeProcessing may be used to change the default escape processing behavior. A value of true (the default) enables escape Processing for all Statement objects. A value of false disables escape processing for all Statement objects. The setEscapeProcessing method may be used to specify the escape processing behavior for an individual Statement object.
    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
    
    Throws:
    
    SQLException - if a database access error occurs or this method is called on a closed Statement
  - getQueryTimeout
```
public int getQueryTimeout()
                    throws SQLException
```
    Description copied from interface: java.sql.Statement
    
    Retrieves the number of seconds the driver will wait for a Statement object to execute. If the limit is exceeded, a SQLException is thrown.
    
    Specified by:
    
    getQueryTimeout in interface Statement
    
    Returns:
    
    the current query timeout limit in seconds; zero means there is no limit
    
    Throws:
    
    SQLException - if a database access error occurs or this method is called on a closed Statement

```
public void setQueryTimeout(int seconds)
                     throws SQLException
```
    Description copied from interface: java.sql.Statement
    
    Sets the number of seconds the driver will wait for a Statement object to execute to the given number of seconds. By default there is no limit on the amount of time allowed for a running statement to complete. If the limit is exceeded, an SQLTimeoutException is thrown. A JDBC driver must apply this limit to the execute, executeQuery and executeUpdate methods.
    Note: JDBC driver implementations may also apply this limit to ResultSet methods (consult your driver vendor documentation for details).
    Note: In the case of Statement batching, it is implementation defined as to whether the time-out is applied to individual SQL commands added via the addBatch method or to the entire batch of SQL commands invoked by the executeBatch method (consult your driver vendor documentation for details).
    
    Specified by:
    
    setQueryTimeout in interface Statement
    
    Parameters:
    
    seconds - the new query timeout limit in seconds; zero means there is no limit
    
    Throws:
    
    SQLException - if a database access error occurs, this method is called on a closed Statement or the condition seconds >= 0 is not satisfied

```
public long getQueryTimeoutMs()
                       throws SQLException
```
    The queryTimeout limit is the number of milliseconds the driver will wait for a Statement to execute. If the limit is exceeded, a SQLException is thrown.
    
    Returns:
    
    the current query timeout limit in milliseconds; 0 = unlimited
    
    Throws:
    
    SQLException - if a database access error occurs
  - setQueryTimeoutMs
```
public void setQueryTimeoutMs(long millis)
                       throws SQLException
```
    Sets the queryTimeout limit.
    
    Parameters:
    
    millis - - the new query timeout limit in milliseconds
    
    Throws:
    
    SQLException - if a database access error occurs
  - addWarning
```
public void addWarning(SQLWarning warn)
```
    Either initializes new warning wrapper, or adds warning onto the chain.
    
    Although warnings are expected to be added sequentially, the warnings chain may be cleared concurrently at any time via clearWarnings(), therefore it is possible that a warning added via this method is placed onto the end of the previous warning chain
    
    Parameters:
    
    warn - warning to add
  - getWarnings
```
public SQLWarning getWarnings()
                       throws SQLException
```
    Description copied from interface: java.sql.Statement
    
    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
  - getMaxFieldSize
```
public int getMaxFieldSize()
                    throws SQLException
```
    Description copied from interface: java.sql.Statement
    
    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
    
    Throws:
    
    SQLException - if a database access error occurs or this method is called on a closed Statement
    
    See Also:
    
    Statement.setMaxFieldSize(int)
  - setMaxFieldSize
```
public void setMaxFieldSize(int max)
                     throws SQLException
```
    Description copied from interface: java.sql.Statement
    
    Sets the limit for 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 fields. If the limit is exceeded, the excess data is silently discarded. For maximum portability, use values greater than 256.
    
    Specified by:
    
    setMaxFieldSize in interface Statement
    
    Parameters:
    
    max - the new column size limit in bytes; zero means there is no limit
    
    Throws:
    
    SQLException - if a database access error occurs, this method is called on a closed Statement or the condition max >= 0 is not satisfied
    
    See Also:
    
    Statement.getMaxFieldSize()
  - clearWarnings
```
public void clearWarnings()
                   throws SQLException
```
    Clears the warning chain.
    
    Note that while it is safe to clear warnings while the query is executing, warnings that are added between calls to getWarnings() and #clearWarnings() may be missed. Therefore you should hold a reference to the tail of the previous warning chain and verify if its SQLWarning.getNextWarning() value is holds any new value.
    
    Specified by:
    
    clearWarnings in interface Statement
    
    Throws:
    
    SQLException - if a database access error occurs or this method is called on a closed Statement
  - getResultSet
```
public ResultSet getResultSet()
                       throws SQLException
```
    Description copied from interface: java.sql.Statement
    
    Retrieves the current result as a ResultSet object. This method should be called only once per result.
    
    Specified by:
    
    getResultSet in interface Statement
    
    Returns:
    
    the current result as a ResultSet object or null if the result is an update count or there are no more results
    
    Throws:
    
    SQLException - if a database access error occurs or this method is called on a closed Statement

  - close
```
public final void close()
                 throws SQLException
```
    Note: even though Statement is automatically closed when it is garbage collected, it is better to close it explicitly to lower resource consumption. 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.
    
    Specified by:
    
    close in interface AutoCloseable

                         throws SQLException
```
    Description copied from interface: PGStatement
    
    Sets the reuse threshold for using server-prepared statements.
    
    If threshold is a non-zero value N, the Nth and subsequent reuses of a PreparedStatement will use server-side prepare.
    
    If threshold is zero, server-side prepare will not be used.
    
    The reuse threshold is only used by PreparedStatement and CallableStatement objects; it is ignored for plain Statements.

```
public int[] executeBatch()
                   throws SQLException
```
    Description copied from interface: java.sql.Statement
    Submits a batch of commands to the database for execution and if all commands execute successfully, returns an array of update counts. The int elements of the array that is returned are ordered to correspond to the commands in the batch, which are ordered according to the order in which they were added to the batch. The elements in the array returned by the method executeBatch may be one of the following:
    1. A number greater than or equal to zero -- indicates that the command was processed successfully and is an update count giving the number of rows in the database that were affected by the command's execution
    2. A value of SUCCESS_NO_INFO -- indicates that the command was processed successfully but that the number of rows affected is unknown
      If one of the commands in a batch update fails to execute properly, this method throws a BatchUpdateException, and a JDBC driver may or may not continue to process the remaining commands in the batch. However, the driver's behavior must be consistent with a particular DBMS, either always continuing to process commands or never continuing to process commands. If the driver continues processing after a failure, the array returned by the method BatchUpdateException.getUpdateCounts will contain as many elements as there are commands in the batch, and at least one of the elements will be the following:
    3. A value of EXECUTE_FAILED -- indicates that the command failed to execute successfully and occurs only if a driver continues to process commands after a command fails
    The possible implementations and return values have been modified in the Java 2 SDK, Standard Edition, version 1.3 to accommodate the option of continuing to process commands in a batch update after a BatchUpdateException object has been thrown.
    Specified by:
    
    executeBatch in interface Statement
    
    Returns:
    
    an array of update counts containing one element for each command in the batch. The elements of the array are ordered according to the order in which commands were added to the batch.
    
    Throws:
    
    SQLException - if a database access error occurs, this method is called on a closed Statement or the driver does not support batch statements. Throws BatchUpdateException (a subclass of SQLException) if one of the commands sent to the database fails to execute properly or attempts to return a result set.
    
    SQLTimeoutException - when the driver has determined that the timeout value that was specified by the setQueryTimeout method has been exceeded and has at least attempted to cancel the currently running Statement

```
public void setPoolable(boolean poolable)
                 throws SQLException
```
    Description copied from interface: java.sql.Statement
    
    Requests that a Statement be pooled or not pooled. The value specified is a hint to the statement pool implementation indicating whether the application 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

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

```
    Description copied from interface: java.sql.Wrapper
    
    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
    
    Type Parameters:
    
    T - the type of the class modeled by this Class object
    
    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:

    current - one of the following Statement constants indicating what should happen to current ResultSet objects obtained using the method getResultSet: Statement.CLOSE_CURRENT_RESULT, Statement.KEEP_CURRENT_RESULT, or Statement.CLOSE_ALL_RESULTS
    
    Returns:
    
    true if the next result is a ResultSet object; false if it is an update count or there are no more results
    
    Throws:
    
    SQLException - if a database access error occurs, this method is called on a closed Statement or the argument supplied is not one of the following: Statement.CLOSE_CURRENT_RESULT, Statement.KEEP_CURRENT_RESULT or Statement.CLOSE_ALL_RESULTS

    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 getMoreResults to move to any subsequent result(s).
    Note:This method cannot be called on a PreparedStatement or CallableStatement.
    
    Specified by:
    
    execute in interface Statement
    
    Parameters:
    
    sql - any SQL statement
    
    columnNames - an array of the names of the columns in the inserted row that should be made available for retrieval by a call to the method getGeneratedKeys
    
    Returns:
    
    true if the next result is a ResultSet object; false if it is an update count or there are no more results
    
    Throws:
    
    SQLException - if a database access error occurs, this method is called on a closed Statement,the elements of the String array passed to this method are not valid column names, the method is called on a PreparedStatement or CallableStatement
    
    SQLFeatureNotSupportedException - if the JDBC driver does not support this method
    
    SQLTimeoutException - when the driver has determined that the timeout value that was specified by the setQueryTimeout method has been exceeded and has at least attempted to cancel the currently running Statement
