CX-Supervisor Script To Modify A CX-Supervisor DB Connection CX-Supervisor allows you to modify the database connection from within a script. This can be done using the DBExecute command as shown in the following example:
dbeSuccess = DBExecute ([myDatabaseConnection], "Connection", [database reference], {User Name}, {Password})Where:
dbeSuccess = the success of the command
[myDatabaseConnection] = The database connection in CX-Supervisor
"Connection" = The command we are using on the database - do not change this
[database reference] = The reference to the database file (e.g. Microsoft Access .accdb file) or File DSN (.dsn) on the disk
{User Name} = Optional User name for a password protected MDB file
{Password} = Optional password for a password protected MDB file
It should be noted that this command does NOT take a replacement connection string as a parameter, it creates a new connection string from the parameters provided.
If using an mdb, accdb or other database file as the {database reference} parameter, CX-Supervisor runtime will select an appropriate installed driver for that database and create a connection string.
If using a File DSN, simply supply the path and filename of the FileDSN as the {database reference} parameter.
If your database is accdb and uses password protection or you use a workgroup or system database, you must create a File DSN containing the correct parameters and switch between DSN files rather than between Access Database files.
For details of supported databases in CX-Supervisor and further information on their use, consult Section 12 of the Manual - Databases. Additionally, remember that CX-Supervisor Machine Edition has support for just the Microsoft Access Database (.mdb and .accdb), if you need to use a File DSN you must upgrade to PLUS Edition.
Example:
Changes the Recipe database to 'Recipe5.accdb'
Changes the Machine details database to be whatever is referred to in the File DSN. Link: |
