Detailed Description

The AESearchedDelete class models the <delete statement: searched> statement in section 13.7 of the SQL-92 spec.

For example, the following SQL query can be translated to an AESearchedDelete operation directly:

DELETE FROM T WHERE cond

It is apparent that a DELETE operation only affects the set of rows returned.


Constructor & Destructor Documentation

AESearchedDelete ( AutoPtr< AETable in_tableOperand,
AutoPtr< AEBooleanExpr in_deleteCond 
)

Constructor.

The ownerships of the operand object and the delete condition object passed in through the constructor are transferred to this object.

Parameters:
in_tableOperand The table operand.
in_deleteCond The delete condition boolean expression.
Exceptions:
SEInvalidArgumentException when either in_operand or in_deleteCond does not own an appropriate object.
AESearchedDelete ( const AESearchedDelete in_other  ) 

Copy constructor.

To support "cloning". See Clone() method.

Parameters:
in_other The other node to create copy from.
virtual ~AESearchedDelete (  )  [virtual]

Destructor.


Member Function Documentation

virtual void AcceptVisitor ( AENodeVisitor in_visitor  )  [virtual]

Calls the correct method on the visitor.

Parameters:
in_visitor The visiting object.

Implements AENode.

virtual AESearchedDelete* Clone (  )  const [virtual]

Creates a clone of this node object.

Returns:
A clone of this node object. (OWN)
