This type of task is complicated to process fields except failure_cause and complete_time are not empty. 2. When the job completes execution, program will update the record, update the columns of is_success, complete_time and failure_cause(if the

Parse Engine Compared to other programming languages, SQL is relatively simple, but it is still a complete set of programming language, so there is no essential difference between parsing SQL grammar and situations to the database.
