Type a valid SQL expression that returns a scalar value. The expression is sent to the provider, and validated in the following expression:
SELECT <Table Name in Data Source>.* , <Expression> AS <Column Name> FROM <Table Name in Data Source> AS <Table Name in Data Source View>
The expression can contain references to other tables, by means of a sub-select statement. If the expression would require parentheses in a SELECT statement, the expression entered must be enclosed between parentheses.
