How to write stored procedure to update the data in 10 tables..

Answer / mohit johri

Hey Vaishaili,
The query you wrote first of all does not require a dynamic
string to be constructed and then executed. The problem
with this is you are defeating the purpose of a stored
procedure.

A stored procedure is basically used to make the execution
faster as the code is kept in pre-complied mode.

Here what you are doing is you are giving an 'EXEC'
statement to execute the query which means that
the 'update'statements are not kept in pre-compiled mode.
They will first compile and then execute just like a normal
SQL statement.

Hence you should directly write the 'UPDATE' statements so
that it should only be executed and not compiled as they
are already kept in a pre-compiled mode.

The procedure can be best written as follows:

CREATE PROCEDURE <<procName>>
(
@param1 varchar(20),
@param2 varchar(20)
)
AS
UPDATE <<tableName1>> SET <<colName1>> = @param1 WHERE
<<colName2>> = @param2

UPDATE <<tableName1>> SET <<colName1>> = @param1 WHERE
<<colName2>> = @param2

..
..
..
..

UPDATE <<tableNameN>> SET <<colName1>> = @param1 WHERE
<<colName2>> = @param2

Exec(@sql)
