Example 2 with ProcedureErrorInstructionException

use of org.teiid.client.ProcedureErrorInstructionException in project teiid by teiid.

the class ProcedurePlan method processProcedure.

/**
 * <p>Process the procedure, using the stack of Programs supplied by the
 * ProcessorEnvironment.  With each pass through the loop, the
 * current Program is gotten off the top of the stack, and the
 * current instruction is gotten from that program; each call
 * to an instruction's process method may alter the Program
 * Stack and/or the current instruction pointer of a Program,
 * so it's important that this method's loop refer to the
 * call stack of the ProcessorEnvironment each time, and not
 * cache things in local variables.  If the current Program's
 * current instruction is null, then it's time to pop that
 * Program off the stack.</p>
 *
 * @return List a single tuple containing one Integer: the update
 * count resulting from the procedure execution.
