AddContext() is for nesting procedure context objects. If one procedure invokes another procedure and the results
of calling the nested procedure are to be returned to the caller of the outer procedure then simply invoke
AddContext on the context object of the outer procedure, passing the context object of the inner procedure as
an argument, pContext. If the propagateerror argument is true then any error encountered by the nested procedure
will be reported as an error to the caller of the outer procedure.
This method will register a temporary table object. Only registered table objects are usable by dSQL.
The TTNI property is the to index and is not set up here
since the actual table (referenced by pTable) has no clue as to the source language table name. That must
be done by the source language.
Called to return the next resultset object.
This also removes the reference to the existing object so it can cleanup and close itself
method RemovePrivateTable(pTableName As %String(MAXLEN=""))
RemovePrivateTable() will remove the private table name from the current context object or the process context
object. The storage offset information remains to that any existing result sets will still be valid. However,
If another instance of a private table with the same name is created any result sets against the prior private
table may become invalid.
ResolveTableName will locate a temporary table registered in either the current object (usually equates to
%sqlcontext) or in the process context object (%processcontext). The temporary table name passed into this
method is the host language name such as #my_temp in TSQL or a normal temporary table name in Informix. This
name is the one bound to the actual name in the TTNI (temporary table name index) by the host language procedure.
If the table name is not found in TTNI, either local(current object) or global (%processcontext) then the name
submitted is returned an no context is returned in the byref pContext argument.
