views, stored procedures, functions, and so on. Therefore, constraints must have unique names across the database. But because every table constraint is scoped to an individual table, it makes sense to adopt a naming convention that states that type of constraint, the table name, and then, i...
In SQLServer, I tried to define a stored procedure to recursively invoke itself (See the following T-SQL statements). However, the maximum nesting level of recursion is 30 (Tested under SQL Server 2000). Once the nesting level is exceeded, an error will occur. Another thing I'd like to ...
You can use nested stored procedures to circumvent this limitation by separating code sections and encapsulating them in sub-procedures. Use IF <condition> EXEC <stored procedure> instead of GOTO. WAITFOR Delay pg_sleep. For more information, see Date/Time Function...

It is good programming practice to use stored procedures for all repetitive actions in the database.For this example, you use CREATE VIEW to create a view that selects only two of the columns in the Products table. Then, you use CREATE PROCEDURE to create a stored procedure that accepts a...
Amazon Aurora MySQL-Compatible Edition (Aurora MySQL) supports cursors only within stored routines, functions and stored procedures. Unlike SQL Server, which offers an array of cursor types, Aurora MySQL cursors have the following characteristics: Asensitive— The server can ...
