Detailed Description

SQL.StatementObject - a StatementObject instances is the metadata for the object attributes of a column whose type class is a persistent class.

This metadata contains the referenced extent name and an expression for exporting the referenced object using an optimized interface.

Member Data Documentation

◆ column

column

column is the collection pointer of the column whose values reference

objects in an extent.  

◆ columnName

columnName

columnName is the name of the column or property whose values reference

objects in an extent. That means that this expression can be used to return an object reference: set objectRef = $classmethod(<extentName>,"%OpenId",rs.Get(<columnName>))  

◆ exportCall

exportCall

exportCall is the tag^routine(<parms>) expression that implements

the object export for a given object ID. The following code will export an instance of extentName: set rowid = rs.Get(<columnName>), nolock = 0 do <exportCall>  

◆ extentName

extentName

extentName is the name of the extent in which the

value of columnNbr is an instance. This is a class name but the object referenced can be an instance of a more specific subclass of extentName.
