Constructor Detail

tinySQLStatement
public tinySQLStatement(tinySQLConnection conn)(Code)
	Constructs a new tinySQLStatement object. Parameters: conn - the tinySQLConnection object

Method Detail

addBatch
public void addBatch(String sql) throws SQLException(Code)
	JDBC 2.0 Adds a SQL command to the current batch of commmands for the statement. This method is optional. Parameters: sql - typically this is a static SQL INSERT or UPDATE statement exception: SQLException - if a database access error occurs, or thedriver does not support batch statements

cancel
public void cancel()(Code)
	This can be used by another thread to cancel a statement. This doesn't matter for tinySQL, as far as I can tell. See Also: java.sql.Statement.cancel

clearBatch
public void clearBatch() throws SQLException(Code)
	JDBC 2.0 Makes the set of commands in the current batch empty. This method is optional. exception: SQLException - if a database access error occurs or thedriver does not support batch statements

clearWarnings
public void clearWarnings() throws SQLException(Code)
	Clear the warning chain associated with this Statement See Also: java.sql.Statement.clearWarnings

close
public void close() throws SQLException(Code)
	Close any result sets. This is not used by tinySQL. See Also: java.sql.Statement.close

execute
public boolean execute(String sql) throws SQLException(Code)
	Executes some SQL and returns true or false, depending on the success. The result set is stored in result, and can be retrieved with getResultSet(); See Also: java.sql.Statement.execute exception: SQLException - raised for any errors Parameters: sql - the SQL to be executed true if there is a result set available

executeBatch
public int[] executeBatch() throws SQLException(Code)
	JDBC 2.0 Submits a batch of commands to the database for execution. This method is optional. an array of update counts containing one element for eachcommand in the batch. The array is ordered according to the order in which commands were inserted into the batch. exception: SQLException - if a database access error occurs or thedriver does not support batch statements

executeQuery
public synchronized ResultSet executeQuery(String sql) throws SQLException(Code)
	Execute an SQL statement and return a result set. See Also: java.sql.Statement.executeQuery exception: SQLException - raised for any errors Parameters: sql - the SQL statement string the result set from the query

executeUpdate
public synchronized int executeUpdate(String sql) throws SQLException(Code)
	Execute an update, insert, delete, create table, etc. This can be anything that doesn't return rows. See Also: java.sql.Statement.executeUpdate exception: java.sql.SQLException - thrown when an error occurs executingthe SQL either the row count for INSERT, UPDATE or DELETE or 0 for SQL statements that return nothing

getConnection
public Connection getConnection() throws SQLException(Code)
	JDBC 2.0 Returns the `Connection` object that produced this `Statement` object. the connection that produced this statement exception: SQLException - if a database access error occurs

getFetchDirection
public int getFetchDirection() throws SQLException(Code)
	JDBC 2.0 Retrieves the direction for fetching rows from database tables that is the default for result sets generated from this `Statement` object. If this `Statement` object has not set a fetch direction by calling the method `setFetchDirection`, the return value is implementation-specific. the default fetch direction for result sets generatedfrom this `Statement` object exception: SQLException - if a database access error occurs

getFetchSize
public int getFetchSize() throws SQLException(Code)
	JDBC 2.0 Retrieves the number of result set rows that is the default fetch size for result sets generated from this `Statement` object. If this `Statement` object has not set a fetch size by calling the method `setFetchSize`, the return value is implementation-specific. the default fetch size for result sets generatedfrom this `Statement` object exception: SQLException - if a database access error occurs

getMaxFieldSize
public int getMaxFieldSize() throws SQLException(Code)
	Get the maximum field size to return in a result set. See Also: java.sql.Statement.getMaxFieldSize the value of max field size

getMaxRows
public int getMaxRows() throws SQLException(Code)
	Get the maximum row count that can be returned by a result set. See Also: java.sql.Statement.getMaxRows the maximum rows

getMoreResults
public boolean getMoreResults() throws SQLException(Code)
	This returns true if there are any pending result sets. This should only be true after invoking execute() See Also: java.sql.Statement.getMoreResults true if rows are to be gotten

getQueryTimeout
public int getQueryTimeout() throws SQLException(Code)
	Discover the query timeout. See Also: java.sql.Statement.getQueryTimeout See Also: setQueryTimeout the timeout value for this statement

getResultSet
public ResultSet getResultSet() throws SQLException(Code)
	Returns the last result set See Also: java.sql.Statement.getResultSet null if no result set is available, otherwise a result set

getResultSetConcurrency
public int getResultSetConcurrency() throws SQLException(Code)
	JDBC 2.0 Retrieves the result set concurrency.

getResultSetType
public int getResultSetType() throws SQLException(Code)
	JDBC 2.0 Determine the result set type.

getSQLString
public String getSQLString()(Code)
	Returns the current query-String

getUpdateCount
public int getUpdateCount() throws SQLException(Code)
	Return the row count of the last operation. tinySQL does not support this, so it returns -1 See Also: java.sql.Statement.getUpdateCount -1

getWarnings
final public SQLWarning getWarnings() throws SQLException(Code)
	Get the warning chain associated with this Statement See Also: java.sql.Statement.getWarnings the chain of warnings

setCursorName
public void setCursorName(String unused) throws SQLException(Code)
	Sets the cursor name for this connection. Presently unsupported.

setEscapeProcessing
public void setEscapeProcessing(boolean enable) throws SQLException(Code)
	If escape scanning is on (the default) the driver will do escape substitution before sending the SQL to the database. See Also: java.sql.Statement.setEscapeProcessing Parameters: enable - this does nothing right now

setFetchDirection
public void setFetchDirection(int direction) throws SQLException(Code)
	JDBC 2.0 Gives the driver a hint as to the direction in which the rows in a result set will be processed. The hint applies only to result sets created using this Statement object. The default value is ResultSet.FETCH_FORWARD. Note that this method sets the default fetch direction for result sets generated by this `Statement` object. Each result set has its own methods for getting and setting its own fetch direction. Parameters: direction - the initial direction for processing rows exception: SQLException - if a database access error occursor the given directionis not one of ResultSet.FETCH_FORWARD, ResultSet.FETCH_REVERSE, orResultSet.FETCH_UNKNOWN

setFetchSize
public void setFetchSize(int rows) throws SQLException(Code)
	JDBC 2.0 Gives the JDBC driver a hint as to the number of rows that should be fetched from the database when more rows are needed. The number of rows specified affects only result sets created using this statement. If the value specified is zero, then the hint is ignored. The default value is zero. Parameters: rows - the number of rows to fetch exception: SQLException - if a database access error occurs, or thecondition 0 <= rows <= this.getMaxRows() is not satisfied.

setMaxFieldSize
public void setMaxFieldSize(int max) throws SQLException(Code)
	set the max field size. See Also: java.sql.Statement.setMaxFieldSize Parameters: max - the maximum field size

setMaxRows
public void setMaxRows(int max) throws SQLException(Code)
	Get the maximum row count that can be returned by a result set. See Also: java.sql.Statement.setMaxRows Parameters: max - the max rows

setQueryTimeout
public void setQueryTimeout(int x) throws SQLException(Code)
	Set the query timeout. See Also: java.sql.Statement.setQueryTimeout See Also: getQueryTimeout Parameters: x - the new query timeout value
