Specifies the ID (oid) of the database associated with this database component.
Syntax:
property DatabaseID: cardinal;
Description:
Use read-only DatabaseID property to get unique integer value which identifies database within cluster.
You can use DatabaseID property for low level calls to server.
Example:
This example shows SQL statement that returns last system inserted OID in the database:
PSQLQuery1.SQL.Text := Format('SELECT datlastsysoid FROM pg_database ' +
'WHERE oid = ''%u''',
[PSQLQuery1.Database.DatabaseID]);
Since OID type is unsigned integer be carefull when mixing integer types in your application!
