Description
The Get current data source command returns the name of the current data source of the application. The current data source receives the SQL queries executed within Begin SQL/End SQL structures.
When the current data source is the local 4D database, the command returns the string ";DB4D_SQL_LOCAL;", which corresponds to the value of the SQL_INTERNAL constant ("External data source" theme).
This command lets you check the current data source, generally before executing an SQL query.
