Compare Date Range columns with Date Range Parameters

Comparing Date Range columns with Date Range Parameters always confuse us.
Here is the simple solution  using below query:


Declare @DateFrom DateTime, @DateTo DateTime
Set @DateFrom = '2012/10/01'
Set @DateTo = '2012/10/30'

Select *
From Schedule
Where
ScheduleFrom < = @DateTo And
ScheduleTo >= @DateFrom

Get Agent Job Name for SSRS Report Subscription

Every time when we create Reporting Service Report subscription , a new Agent Job creates.
Here is the useful script to get Agent Job Name for each subscription :

Use ReportServer
GO
SELECT    
Schedule.ScheduleID AS SQLAgent_Job_Name,
Subscriptions.Description AS SubscriptionName,
Subscriptions.DeliveryExtension AS sub_delExt,
[Catalog].Name AS ReportName, [Catalog].Path AS ReportPath
FROM         ReportSchedule
INNER JOIN Schedule ON ReportSchedule.ScheduleID = Schedule.ScheduleID
INNER JOIN Subscriptions ON ReportSchedule.SubscriptionID = Subscriptions.SubscriptionID
INNER JOIN [Catalog] ON ReportSchedule.ReportID = [Catalog].ItemID AND Subscriptions.Report_OID = [Catalog].ItemID






Or More Advance ...


  SELECT    
 Schedule.ScheduleID AS AgentJobName,
 Subscriptions.Description AS SubscriptionName,
  Subscriptions.DeliveryExtension AS DeliveryExt,
  [Catalog].Name AS ReportName,
  [Catalog].Path AS ReportPath,
 SUBSTRING(ExtensionSettings, LEN('TO') + CHARINDEX('TO', ExtensionSettings), CHARINDEX('', ExtensionSettings, CHARINDEX('TO', ExtensionSettings) + 1) - (LEN('TO') + CHARINDEX('TO', ExtensionSettings))) AS 'To Email recipient List',
CASE CHARINDEX('CC', ExtensionSettings) WHEN 0 THEN
  ''
 ELSE
   SUBSTRING(ExtensionSettings, LEN('CC') + CHARINDEX('CC', ExtensionSettings), CHARINDEX('', ExtensionSettings, CHARINDEX('CC', ExtensionSettings) + 1) - (LEN('CC') + CHARINDEX('CC', ExtensionSettings)))
END AS 'CC Email recipient List',
CASE CHARINDEX('BCC', ExtensionSettings) WHEN 0 THEN
 ''
 ELSE
 SUBSTRING(ExtensionSettings, LEN('BCC') + CHARINDEX('BCC', ExtensionSettings), CHARINDEX('', ExtensionSettings, CHARINDEX('BCC', ExtensionSettings) + 1) - (LEN('BCC') + CHARINDEX('BCC', ExtensionSettings)))

END AS 'BCC Email recipient List'

FROM        
  ReportSchedule
INNER JOIN Schedule  ON   ReportSchedule.ScheduleID = Schedule.ScheduleID
INNER JOIN Subscriptions  ON   ReportSchedule.SubscriptionID = Subscriptions.SubscriptionID
INNER JOIN [Catalog]  ON   ReportSchedule.ReportID = [Catalog].ItemID
AND Subscriptions.Report_OID = [Catalog].ItemID
WHERE
  Subscriptions.DeliveryExtension = 'Report Server Email'

Table Variable in Execute SQL Task SSIS

Yesterday one of my colleague ask me to resolve an issue with table variable in SSIS.

What was that issue, she was trying to use Table variable in "Execute SQL Task", everything was working but no data was loading in table.

After reading an article what we found that by just putting "SET NOCOUNT ON" statement on the top of TSQL script will resolve that issue.

Means when we simply run any SELECT statement then SQL Server returns two sets as an output , one is result of Select statement and second is "no of rows affected by a Transact-SQL statement".

SSIS treat last result as an original output which is not in actual , so by putting  "SET NOCOUNT ON" statement we can stop the last output .

Excel File Connection Manager Connection String Problem

Today I encountered a following error on Sql Server 2012 while creating a basic SSIS package to load multiple Excel Files in database.

[Connection manager "Excel Connection Manager"] Error: The connection string format is not valid. It must consist of one or more components of the form X=Y, separated by semicolons. This error occurs when a connection string with zero components is set on database connection manager.

I spent a couples of minutes to identify issue ,finally found solution:

Choose "Excel File Path" instead of "ConnectionString"while setting expression on Excel Connection Manager .


Hope this full help others who are facing the same problem.

How to list Stored procedure parameters ?

One of the simple way to use sp_Help system stored procedure to get all parameters properties for a particular stored procedure but what if we have to list all stored procedures parameters using TSQL .
Here is a simple query :

Select OBJECT_NAME(SP.OBJECT_ID) AS ProcedureName,
PR.name AS Parameters, TY.name AS DataType, TY.max_length AS Length, TY.precision AS Precision
From sys.procedures SP
Inner Join sys.parameters PR On SP.object_id = PR.object_id
Inner Join sys.types TY On PR.user_type_id= TY.user_type_id
----Where OBJECT_NAME(SP.OBJECT_ID)  = ?

Correlated Subquery SQL Server

Correlated subquery is also known as repeating subquery where subquery depends on outer query of its values. Correlated subquery executes repeatedly once for each row that are selected by outer query.

e.g.
Select *
From Employees E
Where E.EmpID In (Select EmpID From EmployeeSalary Where EmpID = E.EmpID)
