Thanks Michael.
Function signature is
GetSchemaInfoSQL(SchemaType : TSchemaType; SchemaObjectName,
SchemaPattern : string) : string;
... assuming SchemaObjectName would be used similar to the existing code
and would specify table name (stIndexes)/stored proc name
(stProcedureParams)?

I believe package names are unique within dbs in Oracle (don't know
Firebird, IIRC, that's planned for the upcoming 3.0, right?), so no
parameters required for stPackages?

SchemaPattern doesn't seem to be used; perhaps meant as some kind of
filter to limit the results?

I'll implement at least stIndexes for MS SQL Server, perhaps
ProcedureParams as well..
Later on the same for Sybase, perhaps Firebird.


Thanks,
Reinier
