SQL Procedures: Procedures : Procedures are like functions. Procedures are easy to execute and save your time. you do not have to write whole the sql statement again and again. You only have to call the procedure. You must create the table before you can apply procedure on the table. Here I am applying procedures on doctor table General syntax for procedures: create procedure Procedure_Name (   --Parameters ) as begin --Your sql statements End Procedure for inserting records: Create a procedure and specify number of Parameters that will be passed to procedure. Parameters are the columns of table in which you want to insert the record. Number of Parameters should be equal to number of columns of the table . create procedure insertdoc ( @Doctor_Id int ,                                 --Here goes your Parameters @Doc...

SQL Triggers: Triggers are like events which can be fired after performing some operation. Triggers are fired when some modification to data is performed. Triggers can be fired after update,delete and insert operations. General Syntax For Creating a Trigger: create trigger trigger_name on table_name AFTER insert,update,delete   as statements to be executed after trigger fires   Trigger Which Fires After update: Let's see what this trigger do. Give trigger name as in examle that is(updatetrig) then specify table name as(doctor) in example create trigger updatetrig on doctor -- Define when trigger fires as in this case it fires after update   AFTER update as --Define what to perform when trigger fires select * from doctor where doctor_id = 'd101'     --To fire trigger update a record in the table update doctor set name = 'mairaj' where doctor_id = 'd101' Trigger Which Fires After Delete: create trigger deltrig on doctor --Yo...
