Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`void`	`addBatch(java.lang.String sql)` JDBC 2.0 Adds a SQL command to the current batch of commmands for the statement.
`void`	`cancel()` Cancel can be used by one thread to cancel a statement that is being executed by another thread.

public final void close()
                 throws java.sql.SQLException
```
    In many cases, it is desirable to immediately release a Statements's database and JDBC resources instead of waiting for this to happen when it is automatically closed; the close method provides this immediate release.
    Note: A Statement is automatically closed when it is garbage collected. When a Statement is closed its current ResultSet, if one exists, is also closed.
    
    Specified by:
    
    close in interface java.lang.AutoCloseable
    
    Specified by:
    
    close in interface java.sql.Statement

```
    The maxFieldSize limit (in bytes) is the maximum amount of data returned for any column value; it only applies to BINARY, VARBINARY, LONGVARBINARY, CHAR, VARCHAR, and LONGVARCHAR columns. If the limit is exceeded, the excess data is silently discarded.

  - setMaxFieldSize
```
public void setMaxFieldSize(int max)
                     throws java.sql.SQLException
```
    The maxFieldSize limit (in bytes) is set to limit the size of data that can be returned for any column value; it only applies to BINARY, VARBINARY, LONGVARBINARY, CHAR, VARCHAR, and LONGVARCHAR fields. If the limit is exceeded, the excess data is silently discarded.
    
    Specified by:
    
    setMaxFieldSize in interface java.sql.Statement
    
    Parameters:
    
    max - the new max column size limit; zero means unlimited
    
    Throws:
    
    java.sql.SQLException - thrown on failure.
  - getMaxRows
```
public int getMaxRows()
               throws java.sql.SQLException
```
    The maxRows limit is the maximum number of rows that a ResultSet can contain. If the limit is exceeded, the excess rows are silently dropped.

    Cancel can be used by one thread to cancel a statement that is being executed by another thread.
    
    Specified by:

                                throws java.sql.SQLException
```
    The first warning reported by calls on this Statement is returned. A Statment's execute methods clear its SQLWarning chain. Subsequent Statement warnings will be chained to this SQLWarning.
    The warning chain is automatically cleared each time a statement is (re)executed.
    Note: If you are processing a ResultSet then any warnings associated with ResultSet reads will be chained on the ResultSet object.
    
    Specified by:
    
    getWarnings in interface java.sql.Statement
    
    Returns:
    
    the first SQLWarning or null

  - setCursorName
```
public void setCursorName(java.lang.String name)
                   throws java.sql.SQLException
```
    setCursorName defines the SQL cursor name that will be used by subsequent Statement execute methods. This name can then be used in SQL positioned update/delete statements to identify the current row in the ResultSet generated by this statement. If the database doesn't support positioned update/delete, this method is a noop.
    Note: By definition, positioned update/delete execution must be done by a different Statement than the one which generated the ResultSet being used for positioning. Also, cursor names must be unique within a Connection.
    
    Specified by:
    
    setCursorName in interface java.sql.Statement
    
    Parameters:
    
    name - the new cursor name.
    
    Throws:
    
    java.sql.SQLException
  - execute
```
public boolean execute(java.lang.String sql)
                throws java.sql.SQLException
```
    Execute a SQL statement that may return multiple results. Under some (uncommon) situations a single SQL statement may return multiple result sets and/or update counts. Normally you can ignore this, unless you're executing a stored procedure that you know may return multiple results, or unless you're dynamically executing an unknown SQL string. The "execute", "getMoreResults", "getResultSet" and "getUpdateCount" methods let you navigate through multiple results. The "execute" method executes a SQL statement and indicates the form of the first result. You can then use getResultSet or getUpdateCount to retrieve the result, and getMoreResults to move to any subsequent result(s).
    
    Specified by:
    
    execute in interface java.sql.Statement
    
    Parameters:
    
    sql - any SQL statement
    
    Returns:
    
    true if the first result is a ResultSet; false if it is an integer
    
    Throws:
    
    java.sql.SQLException - thrown on failure
    
    See Also:
    
    getResultSet(), getUpdateCount(), getMoreResults()
  - execute

public boolean execute(java.lang.String sql,
                       int autoGeneratedKeys)
