3.3.3. Optimizing VBScript Database Connection Speed

Applies from ChronoScan 1.0.0.49 onwards.

We have added a new function to ChronoScan VBscritps that allows you to maintain an open database connection. This will speed up queries to external data sources.

The new function is:

ChronoApp.CreateAdoDBConnection( DSN, USERNAME, PASSWORD)

DSN: your connection String

USERNAME: User name for the connection, (if not supplied on the DSN)

PASSWORD: Password for the connection, (if not supplied on the DSN)

Creating a new persistent database connection replaces the old ADODB.Connection method:

Example:

Set MyDB = CreateObject("ADODB.Connection")

MyDB.Open "ULISES_JOSE_DEV"

With a call to the new function:

Set MyDB = ChronoApp.CreateAdoDBConnection("ULISES_JOSE_DEV", "", "")

Very Important:

Remember to remove all MyDB.Close calls. ChronoScan will manage the database flow to speed up calls. Avoiding this step may stop your connection.
