All Implemented Interfaces:

java.sql.Statement

Direct Known Subclasses:

vortexPreparedStatement

public class vortexStatement

extends java.lang.Object

implements java.sql.Statement

A Statement object is used for executing a static SQL statement and obtaining the results produced by it.

Only one ResultSet per Statement can be open at any point in time. Therefore, if the reading of one ResultSet is interleaved with the reading of another, each must have been generated by different Statements.

getWarnings

public java.sql.SQLWarning getWarnings()
                                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

Throws:

java.sql.SQLException - Not apply

clearWarnings

public void clearWarnings()
                   throws java.sql.SQLException

Throws:

java.sql.SQLException - Not apply

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 - Not apply

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 - threw exceptions on all DB actions

                throws java.sql.SQLException

Execute a SQL statement that may return multiple results and signal the driver that the auto-generated keys indicated in the given array should be made available for retrieval. This array contains the names of the columns in the target table that contain the auto-generated keys that should be made available. The driver will ignore the array if the given SQL statement is not an INSERT statement. 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).
