sql create or replace

"CREATE OR REPLACE" is a SQL statement used to modify an existing database object such as a stored procedure, view, or trigger. It allows you to replace the existing object with a new definition without having to drop and recreate the object. The syntax for "CREATE OR REPLACE" varies slightly depending on the type of object being modified.

For example, to modify an existing stored procedure named "my_proc", you would use the following syntax:

CREATE OR REPLACE PROCEDURE my_proc AS
BEGIN
  -- Procedure code goes here
END;

This statement will replace the existing definition of "my_proc" with the new code specified in the CREATE OR REPLACE statement.

CREATE OR REPLACE PROCEDURE 在sql存储里

CREATE OR REPLACE PROCEDURE is a SQL statement used to create or modify a stored procedure in a database.

The syntax for creating a stored procedure using CREATE OR REPLACE PROCEDURE is as follows:

CREATE OR REPLACE PROCEDURE procedure_name
(parameter1 datatype, parameter2 datatype, …)
AS
BEGIN
   -- SQL statements
END;

The procedure_name is the name of the stored procedure that you want to create or modify. The parameters are optional and represent the input parameters for the procedure. The SQL statements within the BEGIN and END blocks define the logic of the stored procedure.

If a stored procedure with the same name already exists, using CREATE OR REPLACE PROCEDURE will replace the existing procedure with the new definition. This can be useful when modifying an existing stored procedure without having to drop and recreate it.

Once the stored procedure has been created or modified, it can be executed using the EXECUTE statement.
