interface XStatement
Description 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. All statement `execute` methods implicitly close a statement's current ResultSet if an open one exists.

Methods' Summary
executeQuery | executes a SQL statement that returns a single ResultSet.
executeUpdate | executes an SQL INSERT, UPDATE, or DELETE statement. In addition, SQL statements that return nothing, such as SQL DDL statements, can be executed.
execute | executes a SQL statement that may return multiple results.
getConnection | returns the Connection object that produced this `Statement` object.

Methods' Details
executeQuery
XResultSet
executeQuery( | [in] string | sql )
raises( | SQLException );
Description executes a SQL statement that returns a single ResultSet. Parameter sql the SQL statement which should be executed Returns a ResultSet that contains the data produced by the query; never NULL Throws SQLException if a database access error occurs.
executeUpdate
long
executeUpdate( | [in] string | sql )
raises( | SQLException );
Description executes an SQL INSERT, UPDATE, or DELETE statement. In addition, SQL statements that return nothing, such as SQL DDL statements, can be executed. Parameter sql a SQL INSERT, UPDATE or DELETE statement or a SQL statement that returns nothing Returns either the row count for INSERT, UPDATE or DELETE or 0 for SQL statements that return nothing Throws SQLException if a database access error occurs.
execute
boolean
execute( | [in] string | sql )
raises( | SQLException );
Description executes 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 are (1) executing a stored procedure that you know may return multiple results or (2) you are dynamically executing an unknown SQL string. The navigation through multiple results is covered by XMultipleResults. The `execute` method executes a SQL statement and indicates the form of the first result. You can then use XMultipleResults::getResultSet() or XMultipleResults::getUpdateCount() to retrieve the result, and XMultipleResults::getMoreResults() to move to any subsequent result(s). Parameter sql any SQL statement Returns true if the next result is a ResultSet; false if it is an update count or there are no more results Throws SQLException if a database access error occurs.
getConnection
XConnection
getConnection()
raises( | SQLException );
Description returns the Connection object that produced this `Statement` object. Returns the connection that produced this statement Throws SQLException if a database access error occurs.
