Explanation
The DB Read step executes a SQL query on a database and returns the result in a ResultSet variable. The step has four output branches: Successful, No Data, Timeout, and SQL Error. The Successful branch is taken when the query returns one or more rows. The No Data branch is taken when the query returns zero rows. The Timeout branch is taken when the query execution time exceeds the timeout value specified in the step. The SQL Error branch is taken when the query is invalid or the database connection fails.
