IRelationCollectionToQueryTextNonAnsi Method |
Converts the set of relations to a set of nested JOIN query elements using ANSI join syntaxis. Oracle 8i doesn't support ANSI join syntaxis
and therefore the OracleDQE has its own join code. It uses a database specific creator object for database specific syntaxis, like the format of the
tables / views and fields.

Function ToQueryTextNonAnsi (
ByRef nonAnsiWhereClause As String,
nonAnsiRootTableReference As String,
nonAnsiFieldSuffix As String
) As String
Parameters
- nonAnsiWhereClause
- Type: SystemString
The non ANSI where clause. - nonAnsiRootTableReference
- Type: SystemString
The non ANSI root table reference.
This parameter is set in UPDATE and DELETE statements where a multi-table relation filter is used.
These queries wrap the joins produced with this routine in a subquery and the table used outside the subquery shouldn't be mentioned in the
join list. So if this table reference is in the join list, it is skipped (however field1=field2 statements are added to link the outer table to the
subquery logic). - nonAnsiFieldSuffix
- Type: SystemString
The non ANSI field suffix. For Oracle and PostGresql this is '(+)'.
Return Value
Type:
Stringthe string to use in the FROM clause
Remarks After this calls the parameters produced are in the Parameters collection.
