This is great for when we want to have a result table showing the result of our variable. Posted by: Terry Warren ... is it possible to set the column heading within a stored procedure SELECT statement to the value of an input variable? Very simple example could look like this: [ T-SQL ] DECLARE @CurrentCategory INT is it possible to set the column heading within a stored procedure SELECT statement to the value of an input variable? For example using the stored procedure definition: PROCEDURE sp_sample(IN ex_value CHAR(32)) ... set the value of AS clause name in stored procedure. How To Set Multiple Variables By Using SELECT In Stored Proc . Listed below are the differences between the SET and SELECT statements. Terry Warren. SET @countTotal = (SELECT COUNT(*) FROM Test); SELECT "@countTotal =", @countTotal; After running the above statements, you get this result: 1 MySQL Workbench @countTotal = 1 2. They use the = assignment operator, but the := assignment operator is also permitted for this purpose. The following is your stored procedure to set two variables in a stored procedure with single select statement. For information about the scope of local variables and how MySQL resolves ambiguous names, see Section 13.6.4.2, “Local Variable Scope and Resolution”. A SET statement that assigns variable values is not written to the binary log, so in replication scenarios it affects only the host on which you execute it. 0. Very common task when writing SQL Server stored procedure is to set value of some variable by using the SELECT query. To illustrate: DECLARE @SETVariable INT, @SELECTVariable INT SET @SETVariable = 1 SELECT @SELECTVariable = 2. How MySQL IF ELSE statement can be used in a stored procedure? MySQL provides the DECLARE statement to specify such a variable. The following sections describe SET syntax for setting variables. A procedure has a name, a parameter list, and SQL statement(s). Local Variable Declaration. The query to create a stored procedure is as follows. For this, use stored procedure. Let us first create a table − mysql> create table DemoTable(Id int, Name varchar(100)); Query OK, 0 rows affected (1.51 sec) All most all relational database system supports stored procedure, MySQL 5 introduce stored procedure. A procedure (often called a stored procedure) is a subroutine like a subprogram in a regular computing language, stored in database. For example using the stored procedure definition: PROCEDURE sp_sample(IN ex_value CHAR(32)) BEGIN To affect all replication hosts, execute the statement on each host. set the value of AS clause name in stored procedure. We define local variables in a program like stored procedures. There are 2 ways of assigning a value to a local variable previously created with the DECLARE @LocalVariable statement, namely using the SET and the SELECT statements. Defining local variables inside a stored procedure Syntax to define a (local) variable inside a stored procedure: The SELECT INTO allows for columns to be selected from a table in to variables. MySQL Stored Procedure Variables, In addition to the SET statement, you can use the SELECT INTO statement to assign the result of a query to a variable as shown in the following example:. To store values from the select list into multiple variables, you separate variables by commas. It is not permitted to assign the value DEFAULT to stored procedure or function parameters or stored program local variables (for example with a SET var_name = DEFAULT statement).
