Marking a stored procedure as system object in SQL Server

Once my friend ask to me, It is possible to mark a stored procedure as system object allow to run in user database context?
I said yes we can do. We have to follow two step which is mention below.
Step 1- The stored procedure name must begin with "sp_":
Create a stored procedure in Maser database which name begin with sp_
CREATE PROCEDURE sp_NewObject
@tableNM varchar(100)
AS
BEGIN
       IF EXISTS(SELECT  *
       FROM        sys.objects
       WHERE      name=@tableNM
       )
       BEGIN
              SELECT 'true' [Exist]
       END
       ELSE
       BEGIN
              SELECT 'false' [Exist]
       END
END
GO

























Note: A stored procedure created with "sp_" prefix can be used in any user database without specifying database/schema. But, the procedure still run in the context of master database and not the user database. Let’s create a procedure to test this:
Step 2- The stored procedure must be marked as system object explicitly:
You can mark a stored procedure as system object using sys.sp_MS_marksystemobject system procedure.
Below code will mark the procedure as system object:
USE [master]
GO
EXEC sys.sp_MS_marksystemobject sp_NewObject
GO

 






























You can verify if the object is marked as system object:
USE   [master]

SELECT      name, is_ms_shipped
FROM        sys.objects
WHERE       name = 'sp_NewObject'

result:
name                                    is_ms_shipped
----------------------------------------------------
sp_NewObject                 1
sp_NewObject is now marked as system object and can be run in user database context:


USE   [Your database name]
GO
EXEC  sp_NewObject 'Tbl_Name'
GO

Merge and Merge join transformation in SSIS

MERGE TRANSFORMATION
Using Merge Transformation we can combine two sorted data-set into single data-set basically Merge Transformation used to combines rows from two sorted data flows into one sorted data flow. Following tasks you may perform using Merge Transformation: 1.Suppose we have a scenario like, we need to merge data from a database table and excel means we want to merge data from two different data sources. For such type of scenario, you can use Merge Transformation. 2.If we want to merge data from two same structured tables but exists two different servers. 3.Sometimes we get an error due to data in a row, after correcting errors in the data we can re-merge rows easily. See below explanations may help you to understand Merge Transformation: I do evaluate here, you already know about the data source, data conversion, data flow, task flow, control flow etc. Note:Before Merge transformation, we need to sort the data using Sort Transformation. After sorting data add data path to Merge…

Add day to ISODate in MongoDB

We can use $add operator to add days in ISODate in mongodb, $add is the Arithmetic Aggregation Operator which adds number and date in mongodb.
Syntax:

{ $add: [ <expression1>, <expression2>, ... ] }

Note:  If one of the argument is date $add operator treats to other arguments as milliseconds to add to the date.
Example: Suppose we have a Test collection as below.

{"Title" : "Add day to ISODate in MongoBD","CreatedDate" : ISODate("2016-07-07T08:00:00.000Z")}

Query to add 2 days in CreatedDate

db.Test.aggregate([      { $project: { Title: 1, AddedDate: { $add: [ "$CreatedDate", 2*24*60*60000 ] } } }    ])

Result:

{ "_id" : ObjectId("579a1567ac1b3f3732483de0"), "Title" : "Add day to ISODate in MongoBD", "AddedDate" : ISODate("2016-07-09T08:00:00.000Z") }

Note: As mentioned in above note we have to convert days in millisecond because $add operator treat to other arg…

What is difference between UNION and UNION ALL in SQL Server

We use UNION and UNION ALL operator to combine multiple results set into one result set.
UNION operator is used to combining multiple results set into one result set but removes any duplicate rows. Basically, UNION is used to performing a DISTINCT operation across all columns in the result set. UNION operator has the extra overhead of removing duplicate rows and sorting result.
UNION ALL operator use to combine multiple results set into one result set but it does not remove any duplicate result. Actually, this does not remove duplicate rows so it is faster than the UNION operator. If you want to combine multiple results and without duplicate records then use UNION otherwise UNION ALL is better.
Following some rules for using UNION/UNION ALL operator
1.The number of the column should be the same in the query's when you want to combine them. 2.The column should be of the same data type. 3.ORDER BY clause can be applied to the overall result set not within each result set.
4.Column name of …
