DBStatement (DBvolution 7 0.9.13-SNAPSHOT API)

java.lang.Object
- nz.co.gregs.dbvolution.databases.DBStatement

All Implemented Interfaces:

AutoCloseable, Statement, Wrapper

Direct Known Subclasses:

DBStatementCluster, DBTransactionStatement
```
public class DBStatement
extends Object
implements Statement
```
Encapsulates the JDBC Connection and Statement classes.
You should not need to create a DBStatement as they are managed by the DBDatabase internally.
DBStatement simplifies the JDBC interface by managing the connection and statement simultaneously. When the statement is closed so is the connection ensuring minimalist usage of the database.
Mostly this is a thin wrapper around DBDatabase, Connection, and Statement objects

```
    Discards the current connection, replaces it, and creates a new statement.
    Call this after canceling or closing a statement for a database that close the connection with the statement. Use DBDefinition.willCloseConnectionOnStatementCancel() to detect this situation.
    
    Throws:
    
    SQLException - exceptions from connecting to the database and creating a Statement.
    
    UnableToCreateDatabaseConnectionException - may be thrown if there is an issue with connecting.
    
    UnableToFindJDBCDriver - may be thrown if the JDBCDriver is not on the class path. DBvolution includes several JDBCDrivers already but Oracle and MS SQLserver, in particular, need to be added to the path if you wish to work with those databases.
  - 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.
    Support DBvolution at Patreon
    
    Specified by:
    
    getWarnings in interface Statement
    
    Returns:

  - clearWarnings
```
public void clearWarnings()
                   throws SQLException
```
    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. 1 Database exceptions may be thrown
    
    Specified by:
    
    clearWarnings in interface Statement
    
    Throws:
    
    SQLException - java.sql.SQLException
  - setCursorName
```
public void setCursorName(String string)
                   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. 1 Database exceptions may be thrown
    
    Specified by:
    
    setCursorName in interface Statement
    
    Parameters:
    string - string
    
    Throws:

  - execute
```
public boolean execute(String sql)
                throws SQLException
```
    Executes the given SQL statement, which may return multiple 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).

  - executeBatch
```
public int[] executeBatch()
                   throws SQLException
```
    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
    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
    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 a value of EXECUTE_FAILED.
    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.

  - execute
```
public boolean execute(String string,
              int i)
                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 getMoreResults to move to any subsequent result(s).

    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. 1 Database exceptions may be thrown

  - 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
    
    Type Parameters:
    T - the required interface.

    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. 1 Database exceptions may be thrown
    
    Throws:
    
    SQLException - java.sql.SQLException
  - isWrapperFor
```
public boolean isWrapperFor(Class<?> iface)
                     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:
    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.
