Query to find stored procedures by nested stored procedure name

Problem: Suppose we have a stored procedure which has been used in several stored procedure, I mean stored procedure usp_proc1 is nested in many stored procedures like below

BEGIN
  DECLARE @Result TABLE
  (
    ID INT,
       NAME VARCHAR(50),
       [ADDRESS] VARCHAR(255)
  )
  INSERT INTO @Result
  EXEC usp_proc1 @Name='codefari'
END

So I want to find all those queries who containing usp_proc1
Solution: There is a lot of solutions, I'm giving some of them below.
If you want to get the only name of the stored procedures then use the following query. Using join query on system tables syscomments and sysobjects we can get the stored procedures name which containing the particular table, nested procs or any other string.

SELECT DISTINCT o.name
FROM syscomments s
INNER JOIN sysobjects o ON s.id=o.id
WHERE s.TEXT LIKE '%text for search%'

If you want to get stored procedures and its type then run the following query.

SELECT DISTINCT o.name, o.xtype
FROM syscomments c
INNER JOIN sysobjects o ON c.id=o.id
WHERE c.TEXT LIKE '%text for search%'

We can get the expected result using the following query also, in this query I used only sys.objects table to get the appropriate result. The following query will return sp_name, schema_name, type, and type_desc.

SELECT schema_name(o.schema_id) AS [schema_name],
  NAME AS sp_name
  ,type
  ,o.type_desc
FROM sys.objects o
WHERE o.is_ms_shipped = 0
  AND OBJECT_DEFINITION(object_id) Like '%text for search%'
  AND type = 'p' ORDER BY o.NAME

We can get the appropriate result using table sysdepends and sysobjects see the following query. It will return all those records of stored procedures and its dependent stored procedures. If you want to apply a filter then un-comment the AND condition.

SELECT o.name sp_name, dpt.name nested_spname
 FROM sysdepends d
INNER JOIN sysobjects o on d.id = o.id
INNER JOIN sysobjects dpt on d.depid = dpt.id
WHERE o.xtype = 'P' AND dpt.xtype = 'P'
--AND dpt.name like '%text for search%'

Using system procedure sp_depends we can get the all expected records, see the following query.

EXEC sp_depends @objname = N'proc name';

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 …

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…

Check if an index exists in SQL Server

Many times we come across the scenario where we need to some code based on whether an index exists or not.
The following query may help you to check an index is exists in a particular table or not. Suppose we have a table like dbo.Table1 and it has index idx_Index and in some scenario, we need to check idx_Index exists or not.

System.index catalog view records for each Clustered and Non-Clustered indexes.  We can execute the following query to find out a particular index exists or not in a particular table

IFEXISTS (   SELECT 1 FROMsys.indexes   WHEREname='idx_Index'ANDobject_id=OBJECT_ID('dbo.Table1') ) BEGIN PRINT'Index is Exists' END
