Class vortexStatement

java.lang.Object

vortex.sql.vortexStatement

All Implemented Interfaces:

java.lang.AutoCloseable, java.sql.Statement, java.sql.Wrapper

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.

Specified by:

executeUpdate in interface java.sql.Statement

close

public 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.sql.Statement

Throws:

java.sql.SQLException - Not apply

Throws:

java.sql.SQLException - Not apply

getMaxRows

public int getMaxRows()
               throws java.sql.SQLException

the current max row limit; zero means unlimited

Throws:

java.sql.SQLException

setMaxRows

public void setMaxRows(int max)
                throws java.sql.SQLException

The maxRows limit is set to limit the number of rows that any ResultSet can contain. If the limit is exceeded, the excess rows are silently dropped.

This does not apply to VORTEXjdbc

Specified by:

setMaxRows in interface java.sql.Statement

Parameters:

Throws:

java.sql.SQLException - Not apply

getQueryTimeout

public int getQueryTimeout()
                    throws java.sql.SQLException

The queryTimeout limit is the number of seconds the driver will wait for a Statement to execute. If the limit is exceeded a SQLException is thrown.

Specified by:

getQueryTimeout in interface java.sql.Statement

Returns:

the current query timeout limit in seconds; zero means unlimited

Throws:

java.sql.SQLException - Not apply

setQueryTimeout

public void setQueryTimeout(int seconds)
                     throws java.sql.SQLException

The queryTimeout limit is the number of seconds the driver will wait for a Statement to execute. If the limit is exceeded a SQLException is thrown.

Specified by:

setQueryTimeout in interface java.sql.Statement

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

After this call getWarnings returns null until a new warning is reported for this Statement.

Specified by:

clearWarnings in interface java.sql.Statement

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

getCursorName

public java.lang.String getCursorName()

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).

VORTEXjdbc GENESIS SQL does not support multiple results.

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

closeOnCompletion

public void closeOnCompletion()
                       throws java.sql.SQLException

Not supported by VORTEXjdbc. Specifies that this Statement will be closed when all its dependent result sets are closed. If execution of the Statement does not produce any result sets, this method has no effect. Multiple calls to closeOnCompletion do not toggle the effect on this Statement. However, a call to closeOnCompletion does affect both the subsequent execution of statements, and statements that currently have open, dependent, result sets.

Specified by:

closeOnCompletion in interface java.sql.Statement

Throws:

java.sql.SQLException - - if this method is called on a closed Statement

isClosed

public boolean isClosed()
                 throws java.sql.SQLException

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 java.sql.Statement

Returns:

true if this Statement object is closed; false if it is still open

Throws:

java.sql.SQLException - - if a database access error occurs

isPoolable

public boolean isPoolable()
                   throws java.sql.SQLException

Returns a value indicating whether the Statement is poolable or not.

Specified by:

isPoolable in interface java.sql.Statement

Returns:

true if the Statement is poolable; false otherwise

Throws:

java.sql.SQLException - - if this method is called on a closed Statement

setPoolable

public void setPoolable(boolean poolable)
                 throws java.sql.SQLException

Not supported by VORTEXjdbc. 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 java.sql.Statement

Parameters:

poolable - requests that the statement be pooled if true and that the statement not be pooled if false

Throws:

java.sql.SQLException - - if this method is called on a closed Statement
