db2 stored procedure example

might notice the specification includes a cursor method for directly Calling stored programsthe callproc cursor method. The Callprocmethod is not implemented in MySQLdb as we went to press, although the maintainer of My SQLdb, Andy Dustman, is working on a implementation that would likely be available by the time you read this. Check out the book's Web site (see the preface) for an update. This method isn't implemented in MYSQLDB (version 1.2, at lea

select_news (1, @ title );Among them, 1 is the information number we want to pass in, and title is the title of the corresponding information number to be returned. because it is OUT, we need to add @ in front of it for calling outside the process.

, first we must be familiar with some basic T-SQL statements, because stored procedures are made up of a set of T-SQL statements, and we need to understand some concepts about functions, procedures, because we need to call the stored procedure in the application, just as we call the function of the application, but the calling method is somewhat different.
