Thank you for your guidance.
Params in tdatabase is not assigned a value,
Database: = 'user name = sa Password = password '.
Is the database local or on another server? Are you authorized to access the database? The user name and password must be added when accessing the database ,,
The user and password for accessing the database are not set. The setting is OK.
