Why stored procedure is better than query?
Reusability of Cached Query Plans Stored procedures improve database performance as they allow cached query plans to be reused.
In the case of dynamic SQL, you will have to use parameterized queries to increase cached query plan reusability..
Why stored procedures are faster than functions?
Stored Procedures can be fast, very fast, as they are pre-compiled. The optimiser does not have to work out the execution plan each time. A Stored Procedure will return results in a table form. Functions can be Scalar (returning a single result) or return Tabular data.
Why do we need triggers?
Triggers help the database designer ensure certain actions, such as maintaining an audit file, are completed regardless of which program or user makes changes to the data. … The programs are called triggers since an event, such as adding a record to a table, fires their execution.
Why Stored procedures are bad?
Stored procedures require you to reinvent wheels. … Very often, you will end up reinventing these wheels using copy and paste code, which again is a bad practice. Stored procedures are difficult to unit test. With an ORM, you can mock your database code so as to be able to test your business logic quickly.
What are the after triggers?
After Trigger in SQL Server These kinds of triggers fire after the execution of an action query that can be either DDL statements like Create, Alter and Drop or DML statements like Insert, Update and Delete.
What is stored procedure advantage and disadvantage?
Advantage: Stored procedures can be used to maintain data integrity and enforce database policy without relying on an external program to do so. Disadvantage: Can make debugging more complex. Can also be sensitive to being dropped during copy operations, if not done correctly.
Why use stored procedures?
Following are the advantages of stored procedures:Since stored procedures are compiled and stored, whenever you call a procedure the response is quick.you can group all the required SQL statements in a procedure and execute them at once.Since procedures are stored on the database server which is faster than client.More items…•
Which is faster stored procedure or query?
“Stored procedures are precompiled and cached so the performance is much better.” Stored procedures are precompiled and optimised, which means that the query engine can execute them more rapidly. By contrast, queries in code must be parsed, compiled, and optimised at runtime.
What are the disadvantages of stored procedures?
The main disadvantages of stored procedures are given below:Testing – Testing of a logic which is encapsulated inside a stored procedure is very difficult. … Debugging – … Versioning – … Cost – … Portability –
Which is faster inline query or stored procedure?
From my experience, Stored Procedures are definitely faster, because of decreased network traffic (don’t have to send the whole query) and caching of the procedure and query plans. I ran code similar to the following on a table filled with user logon data. It took 2 hours to run the query on 7000 computer names.
Why we should not use triggers?
Triggers can cause performance issues if not written carefully and not enough developers are knowledgeable enough to write them well. … Triggers are often slower than other means of maintaining data integrity, so if you can use a check constraint, use that instead of a trigger.
How do you run a trigger?
Running a TriggerFrom the Tables folder in Enterprise Explorer, select the table where the trigger is located and expand it.Right-click the trigger and select Run. … Make sure the Trigger field in the Type frame is selected.To modify the trigger SQL, click the SQL… … Construct a query with Visual SQL, and choose OK when you are done.More items…
