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

clearWarnings

public void clearWarnings()
                   throws java.sql.SQLException
After this call getWarnings returns null until a new warning is reported for this Statement.

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

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

                             throws java.sql.SQLException
JDBC 3.0 Moves to this Statement obect's next result, deals with any current ResultSet object(s) according to the instructions specified by the given flag, and returns true if the next result is a ResultSet object

Specified by:
getMoreResults in interface java.sql.Statement

getGeneratedKeys

public final java.sql.ResultSet getGeneratedKeys()
                                          throws java.sql.SQLException
JDBC 3.0 Retrieves any auto-generated keys created as a result of executing this Statement object. If this Statement is a non-insert statement, a null ResultSet object is returned.

getGeneratedKeys in interface java.sql.Statement

executeStatement

protected boolean executeStatement(org.apache.derby.iapi.sql.Activation a,
                                   boolean executeQuery,
                                   boolean executeUpdate)
                            throws java.sql.SQLException
Execute the current statement.

getWarnings

protected void getWarnings(java.sql.SQLWarning sw)

getSQLText

public java.lang.String getSQLText()

getParameterValueSet

public org.apache.derby.iapi.sql.ParameterValueSet getParameterValueSet()

checkStatus

protected final void checkStatus()
                          throws java.sql.SQLException

checkExecStatus

protected final void checkExecStatus()
                              throws java.sql.SQLException
A heavier weight version of checkStatus() that ensures the application's Connection object is still open. This is to stop errors or unexpected behaviour when a [Prepared]Statement object is used after the application has been closed. In particular to ensure that a Statement obtained from a PooledConnection cannot be used after the application has closed its connection (as the underlying Connection is still active). To avoid this heavier weight check on every method of [Prepared]Statement it is only used on those methods that would end up using the database's connection to read or modify data. E.g. execute*(), but not setXXX, etc.

clearResultSets

protected void clearResultSets()
                        throws java.sql.SQLException
Close and clear all result sets associated with this statement from the last execution.

checkRequiresCallableStatement

protected void checkRequiresCallableStatement(org.apache.derby.iapi.sql.Activation activation)
                                       throws java.sql.SQLException
Check to see if a statement requires to be executed via a callable statement.

transferBatch

public void transferBatch(EmbedStatement other)
                   throws java.sql.SQLException
Transfer my batch of Statements to a newly created Statement.

processDynamicResults

private boolean processDynamicResults(java.sql.ResultSet[][] holder,
                                      int maxDynamicResultSets)
                               throws java.sql.SQLException

resultSetClosing

void resultSetClosing(EmbedResultSet closingLRS)
                throws java.sql.SQLException
Callback on the statement when one of its result sets is closed. This allows the statement to control when it completes and hence when it commits in auto commit mode. Must have connection synchronization and setupContextStack(), this is required for the call to commitIfNeeded().

getEmbedConnection

protected final EmbedConnection getEmbedConnection()
Return a reference to the EmbedConnection

getConnectionSynchronization

protected final java.lang.Object getConnectionSynchronization()
Return an object to be used for connection synchronization.

handleException

protected final java.sql.SQLException handleException(java.lang.Throwable t)
                                               throws java.sql.SQLException
Handle any exception.

handleException

protected final java.sql.SQLException handleException(java.lang.Throwable t,
                                                      boolean close)
                                               throws java.sql.SQLException
Handle any exception.

needCommit

protected final void needCommit()
If Autocommit is on, note that a commit is needed.

commitIfNeeded

protected final void commitIfNeeded()
                             throws java.sql.SQLException
Perform a commit if one is needed.

commitIfAutoCommit

protected final void commitIfAutoCommit()
                                 throws java.sql.SQLException
Perform a commit if autocommit is enabled.

setupContextStack

protected final void setupContextStack()
                                throws java.sql.SQLException
Setup the context stack (a.k.a. context manager) for this connection.

restoreContextStack

protected final void restoreContextStack()
                                  throws java.sql.SQLException
Setup the context stack (a.k.a. context manager) for this connection.

getContextManager

public org.apache.derby.iapi.services.context.ContextManager getContextManager()

getDatabase

public org.apache.derby.iapi.db.Database getDatabase()

getCal

protected java.util.Calendar getCal()
Get and save a unique calendar object for this JDBC object. No need to synchronize because multiple threads should not be using a single JDBC object. Even if they do there is only a small window where each would get its own Calendar for a single call.
