Searches a session's list of database components for a specified database. function FindDatabase(const DatabaseName: String): TABSDatabase;
Description
Call FindDatabase to determine whether or not a specified database is associated with a session. DatabaseName specifies the name of the database component for which to search.
FindDatabase compares DatabaseName to the DatabaseName property for each database component in a session's list. If a match is found, FindDatabase returns a pointer to the database component. Otherwise FindDatabase returns nil.
An application can call FindDatabase to see if a database component already exists before creating a new database component for a session.
var
DB: TABSDatabase;
begin
DB := Session.FindDatabase('DBDEMOS');
if (DB = nil) then{ database doesn't exist for session so,}
DB := Session.OpenDatabase('DBDEMOS'); { create and open it} if Assigned(DB) and DB.Active then begin
DB.StartTransaction;
...
end;
end;
