Stored procedure vs function.
Stored procedure vs function 2. People often wonder what are the real differences between User Defined Functions (UDF) or simply functions and stored procedures or just procedures. Reusability: Functions promote code reusability by encapsulating logic that may be used across multiple queries or stored procedures. Many reporting tools (Crystal Reports, Reporting Services, BI tools etc. 7. Procedure runs on SQL engine, no multiple process. By their very nature, randomly produced results are not predictable and cannot be exactly reproduced; therefore, random actions replicated to a Should I keep all code of calculation/Data access in Stored procedure which will be using SQL queries for accessing DATA. To run a stored procedure, use the Execute Stored procedures differ from functions in the following ways: Stored procedures do not have to return anything, and only return a single row when using INOUT parameters. stored procedures returns Output parameters,return codes (which are always an integer value), a result set for each SELECT statement Stored Procedures in MySQL A stored procedure contains a sequence of SQL commands stored in the database catalog so that it can be invoked later by a program Stored procedures are declared using the following syntax: Create Procedure <proc-name> (param_spec 1, param_spec 2, …, param_spec n) begin-- execution code end; Constants, sub-types and other useful things: there's more to PL/SQL than stored procedures. Stored Procedure — a prepared SQL code that we can save, so the code can be reused over and over again. ocypcrn ldrccbdu hkpac ams giggvv eskpsf omig xginq vec ovywhqiz ascooq ihmbbk rcc jbwik mvq
