Transact SQL :: Delta Process In Stored Procedure
Apr 30, 2015
Currently through my stored procedure, I am pulling the data from my source systems in the way Daily Truncate and loading the data in to my database table. Currently my query looks as follows,
SELECT
a.col1,a.col2,b.col3,b.col4,c.col5
FROM
a
left outer join b ON a.col1 = b.col1
left outer join c ON b.col1 = c.col1.
Now, I want to change the above one to delta process(I have updateddate field in all the tables). The requirement is any of these 3 tables has updateddate = getdate() then i need to take "a.col1,a.col2,b.col3,b.col4,c.col5" columns and push to destination
table.
I think usually delta process means we will use to consider the key table, in that table if there is an updated record will take that record and join with the other required tables to pull the updated record. But these logic seems different.how to build the query for the above delta process? Since it is an urgent requirement need to implement asap.

INSERT INTO @MaxCountHistogram
VALUES(432,3,'20150530',10.2564),(432,3,'20150630',13.2564),(432,5,'20150530',8),(432,5,'20150630',13),(433,3,'20150530',9),(433,3,'20150630',11),(433,5,'20150530',13),(433,5,'20150630',21)
I need to take for each Publication and Provider and getting the diferential between two different months, for example:
Period Delta Amount Provider PublicationId

I am trying to follow an exercise for debugging a stored procedure in the .net IDE. I have had success in adding a connection to the application, until I get the point of where I should set a BreakPoint in the stored procedure "Ten Most Expensive Products" which belongs to the Northwind database. When I open Sever Explorer -->Data Connections- ->WI0001.NorthWind.dbo-->Stored Procedures and Right-click the procedure, the context menu does not give me an edit item to select to open this SP in the editor. Nor can I double-click on the stored procedure to open it either.

Hi All,
I am trying to create a CLR based stored procedure in C#. When i tried printing simple "Hello" from it, it works fine.

I have a C# SQL 2005 .net stored procedure which scrubs a text file looking for characters not in a range of characters and replacing them with another character. This works fine except when the process is killed. When this happens the file handle of the file being scrubbed is not released. I use a try catch finally block when opening the file and the output file. The finally section fiushes the output file and closes all files and streams but still when I go to access the file again or use the file in explorer it says the file is still in use. Should I be handling this some other way? How do I know the files will always be closed correctly.

I'm trying to write a stored procedure that performs a select statement of the RequestID column and the total of the disk size for that row. ie the values on RequestAdditionalDisk1Size + RequestAdditionalDisk2Size + RequestAdditionalDisk3Size where the Requester equals a certain value. I can perform the select statement fine on the individual values, how to add the values of the Disk sizes together and present that back in the select statement.So far the code looks like but is giving me an error around the line performing a SUM.

We've researched this, and some people are stating convert to nvarchar first. I'd like to keep the date as a date.Here is how I am trying to call it:
Declare @FromDate as date
Declare @ToDate as date
Set @FromDate=Convert(date,'09-01-2015',110)
Set @ToDate= Convert(Date,'10-13-2015',110)
Select @FromDate
[code]...
How can I keep the date as a date and still pass it to stored procedure.

I am trying to use the Transact-SQL debugger to step through a stored procedure on a server to determine where it is failing. I right-click the stored procedure I want to debug in the Query Analyzer's Object Browser and choose Debug... In the Debug Procedure dialog I fill in the values for the parameters, choose the Auto roll back checkbox, and press Execute.
The T-SQL Debugger screen comes up with my stored procedure and a message on the bottom of Waiting for user input. But I can input nothing, neither click on the icons on top, set breakpoints, or doing anything else, as the stored procedure runs to the end and gives me the return code.
If I subsequently set some breakpoints in my stored procedure and try the Go button. Once again the stored procedure runs to the end without stopping at any breakpoint.
In both cases, the stored procedure shows the waiting icon as it proceeds to the end, so that I can not click on anything to stop it.
I have been told this is may be a permissions issue between myself as a client on my machine and the stored procedure on the server. If so, does anybody know what I the things that have to be done on the permissions side to be able to debug the stored procedure using the Transact SQL debugger.

I needed to create a stored procedure to lock a user who makes 3 incorect entries of his password. I did it successfully. Now the problem what i have is that i want to lock the user only if he makes the 3 incorrect entries within 30 minutes.
I created a field named "FirstEntryTime" of type datetime that saves the date of the first incorrect entry. I tried to make an if statement:
if (@timesOfEntry <=2 AND DATEDIFF(MINUTE, firstEntryTime,GETDATE()) <= 30)
Begin
Update myTable set ...

I need to create a stored procedure for total count of the user's. If User from front end invites other user to use my tool, that user will be stored into a table name called "test",lets say it will be stored as"Invited 1 User(s)" or if he invites 2 users it will store into table as "Invited 2 User(s)."
But now we have changed the concept to get the ISID (name of the user) and now when ever the user invites from the front end, the user who have invited should stored in two tables "test" and " test1" table .
After we get the data into test and test1 table i need the total count of a particular user from both tables test and test1.
if i invite a user , the name of the user is getting stored in both test and test1 tables.Now i want to get the count of a user from both tables which should be 1,but its showing 2.
Reason: Why i am considering the count from 2 tables is because before we were not tracking the usernames and we were storing the count in single test table.,but now we are tracking user names and storing them in both tables(test and test1).
Here is my sample code:
I need to sum it up to get the total user's from both the table but I should get 1 instead of 2
SELECT
(select distinct COUNT(*) from dbo.test
where New_Values like '%invited%'
and Created_By= 'sam'
+
(select distinct count (*) from dbo.test1
where invited_by ='sam'

I need to do 3 scenarios in this table.
1.First i need to update the row if the status column is 0 to 1
2.Need to insert the row IF SegmentId=@SegmentId and SubjectId<>@SubjectId and StaffId=@StaffId
3.Need to insert the row IF StaffId<>@StaffId And ClassId=@ClassId and SegmentId<>@SegmentId and SubjectId<>@SubjectId
I have wrote the stored procedure to do this, But the problem is If do the update, It is reflecting in the database by changing 0 to 1. But it shows error like cannot insert the duplicate
Here is the stored Procedure what i have wrote
ALTER PROCEDURE [dbo].[InsertAssignTeacherToSubjects]
@AcademyId uniqueidentifier,
@StaffId uniqueidentifier,
@ClassId uniqueidentifier,
@SegmentId uniqueidentifier,

I have a SQL server instance being used as our data warehousing environment. The instance consists of several databases that I am snapshotting as part of our high availability strategy for data. I've created a stored procedure that takes the source database as an argument and that will create a new snapshot when a new one needs to be created and will also automatically remove the old snapshot. It also updates some synonym tables that point to the new snapshot but that might not be an important detail.
I would like to have the stored procedure stored some place global to all of the databases that I am routinely snapshotting, but that would mean putting it in the master database. Although having it there makes things significantly better in terms of usability, it seems like there's something wrong with putting any stored procedures in the master database. Am I wrong? Is it OK to put stored procedures there in situations like this?

I appear to be having an issue where the @LetterVal and @Numeric variables aren't resetting for each loop iteration, so if no results are found, it just returns the previous loops values since they aren't overwritten. Below is the stored procedure I've created:
ALTER PROCEDURE [dbo].[ap_CalcGrade]
-- Add the parameters for the stored procedure here
@studId int,
@secId int,
@grdTyCd char(2),
@grdCdOcc int,
@Numeric int output,
[Code] ....
And below is the "test query" I'm using:
-- *** Test Program ***
Declare @LetterVal varchar(2), -- Letter Grade
@Numeric int, -- Numeric Grade
@Result int -- Procedure Status (0 = OK)
Execute @Result = dbo.ap_CalcGrade 102, 86, 'QZ', 3,
[Code] ....
This is resulting in an output of:
A+ 97
A+ 97
C- 72
but it should be returning the output below due to the 2nd data set not being valid/found in the sp query:
A+ 97
No Find
C- 72
I'm sure this is sloppy and not the most efficient way of doing this, so whats causing the errant results, and if there is any better way I should be writing it. Below is the assignment requirements:
Create a stored procedure using the STUDENT database called ap_CalcGrade that does the following:
1. Accepts as input STUDENT_ID, SECTION_ID, GRADE_TYPE_CODE, and GRADE_CODE_OCCURRENCE
2. Outputs the numeric grade and the letter grade back to the user
3. If the numeric grade is found, return 0, otherwise return 1
4. You must use a cursor to loop through the GRADE_CONVERSION table to find the letter grade
