I am looking for standard sql code for below 2 concern.
1- I want to drop the column Rowchecksum to all the table where table name start with ArchiveBbx
2-I want to update all the table where table name start with ArchiveBbx
example:-
Update table Archivebbxfbcc
set Rowchecksum=HASHBYTES('MD5', CAST(CHECKSUM(Col001, Col002, Col003, Col004) AS varchar(max)))
I have a student table like this studentid, schoolID, previousschoolid, gradelevel.
I would like to load this table every day from student system.
During the year, the student could change schoolid, whenever there is a change, I would put current records schoolid to the previous schoolid column, and set the schoolid as the newschoolid from student system.
My question in my merge statement something like below
Merge into student st
using (select * from InputStudent ins)
on st.id=ins.studentid
When matched then update
set st.schoolid=ins.schoolid
, st.previouschoolid= case when (st.schoolid<>ins.schoolid) then st.schoolid
else st.previouschoolid
end
, st.grade_level=ins.grade_level
;
My question is since schoolid is et at the first line of set statement, will the second line still catch what is the previous schoolid?
My question: Is it okay to drop all the auto generated column statistics? (for the following scenario)
- I am cleaning up unnecessary objects (tables, unused indexes, overlapping statistics etc) from databases and found out there are more than 1400 auto generated column statistics on one database (lets call it A).
- Database A was used to be our reporting database but from last several years we are using database B for reporting. DB A has all the historical data while DB B only has valid records.
- We are updating all the column statistics with full scan nightly on database A and it is talking almost 2.5 hours to do that. Now I want to drop all the "unnecessary" statistics those were created when DB A was reporting database and they are no longer in use. There is no way to know the creation date of the column statistics that I know of. Statistics "last update date" is of no use because of our nightly job. So I was thinking of dropping all the auto generated column statistics and let the sql server create as it needs from now.
my table payment_details structure is
payment_id payment_code
1 null
2 null
3 null
4 null
here payment_id is a primary key and i need to update the whole payment_id column to payment_code column.so i just tried the below query
update payment_details
set payment_code = payment_no
where payment_code is null
but it shows subquery error?
I am writing a query to update table variable. It is throwing me some error.
I have a table variable declared and inserted the data with three columns. I want to update col1 of that table variable when the second column of that table variable= one column from a physical table
update @MYtabvar set @Mytabvar.LatestDate=B.LatestDate from TableB B where @Mytabvar.id=B.ID
In a t-sql 2012 stored procedure, I would like to know how I can complete the task I am listing below:
In an existing t-sql 2012 stored procedure, there is a table called 'Atrn' that is truncated every night. The Table 'Atrn' has a column called 'ABS' that is populated with incorrect data.
The goal is to place the correct value into 'ABS' column that is located in the Atrn table while the t-sql 2012 stored procedure is excuting.
**Note: The goal is to fix the problem now since it is a production problem. The entire stored procedure that updates the 'dbo.Atrn' table will be rewritten in the near future.
My plan is to:
1. create a temp table called '#Atrnwork' that will contain the columns called,
Atrnworkid int, and ABSvalue with a double value.
2. The value in the column called Atrnworkid in the '#Atrnwork' table, will obtain its value from the key of the 'Atrn' called atrnid by doing a select into. At the same time, the value for ABSvalue will be obtained by running some sql when the select into occurs?
3. The main table called 'Atrn' will be changed with a update statement that looks something like:
Update Atrn
set ABS = ABSvalue
join Atrn.atrnid = #Atrnwork.Atrnworkid
In all can you tell me what a good solutiion is to solve this problem and/or display some sql on how to solve the problem listed above?
In a stored procedure I dynamically create a temp table by selecting the name of Applications from a regular table. Then I add a date column and add the last 12 months. See attachment.
So far so good. Now I want to update the data in columns by querying another regular table. Normally it would be something like:
UPDATE ##TempTable
SET [columName] = (SELECT SUM(columName)
FROM RegularTable
WHERE FORMAT(RegularTable.Date,'MM/yyyy') = FORMAT(##TempMonths.x,'MM/yyyy'))
However, since I don't know what the name of the columns are at any given time, I need to do this dynamically.
how can I get the column names of a Temp table dynamically while doing an Update?
We have an application that runs Jobs, each of which affect ## number of child objects (usually around 1M). When a thread gets to 5000 updated child objects it bulk inserts into a table called ActionLog with the child Id and JobId.
When the job is complete a sproc SUMs the children from the ActionLog table:
select sum(id) from ACTIONLOG where JOBID = @JobId;
It then updates the Jobs table AffectedObjectCount column with the sum(*) from above.
Instead of writing to the ActionLog table and calculating the SUM at the end I would like to do this 'real time'. After the bulk insert I would like to update the AffectedObjectCount column with the number of rows that were just bulk inserted. I tried this in the past and ran into major contention issues. There are usually 20 threads running a job so there exists a lot of potential for deadlocks.
Is there a recommended way to handle updating one column on one row from multiple threads? What is the best practice for a counter like this?
I have a four tables called plandescription, plandetail and analysisdetail. The table plandescription has the columns DetailQuestionID which is the primary and identity column and a QuestionDescription column.
The table plandetail consists of the column PlanDetailID which the primary and identity column, DetailQuestionID which is the foreign key attribute of plandescription table and a planID column.
The third table analysisdetail consists of a analysisID which the primary and identity column, PlanDetailID which is the foreign key attribute of plandetail table and a scenario.
Below is the schema of the three tables
I have a two web form that will insert, update and delete data into these three tables in a two transaction. One web form will perform CRUD operations in plandescription and plandetail table. When the user inserts QuestionDescription and planid in this web form, I will insert the QuestionDescription Value in the plandescription table and will generate a DetailQuestionID value and this value is fed to the plandetail table with the planid. Here I will generate a PlanDetailID.
Once this transaction is done, I will show the second web form in which the user enters the scenario and this will be mapped with the plandescription using the PlanDetailID.
This schema cannot be changes as this is the client requirement. When I insert values I don’t have any problem. However when I update existing data, I need to delete existing PlanDetailID in the plandetail table and recreate PlanDetailID data for that DetailQuestionID and planID. This is because, the user will be adding or deleting a planID associated with the QuestionDescription.
Once I recreate PlanDetailID for that DetailQuestionID and planID, I need to update the old PlanDetailID with the new PlanDetailID in the third table analysisdetail for the associated analysisID.
I created a #Temp table called #DetailTable to insert the values analysisID, planid and old PlanDetailID and new PlanDetailID so that I can have them in update statement once I delete the data from plandetail table for that PlanDetailID.
Then I deleted the plandetailid from the plandetail table and recreate PlanDetailID for that DetailQuestionID. During my recreation I fetched the new PlanDetailID’s created into another temp table called #InsertedRows
After this I am running a while loop to update the temp table #DetailTable with the newly created PlanDetailID for the appropriate planID’s. The problem is here. When I have the same number of planID’s for example 2 planID’s 1,2 I will have only two old PlanDetailID and new PlanDetailID for that planID and analysisID.But When I add a new PlanID or remove a existing planID I am getting null value for that newly added or deleted planID. This is affecting my update statement of analysisdetail table as PlanDetailID cannot be null.
I tried to remove the Null value from the #DetailTable by running the update statement of analysis detail in a while loop however its not working.
DECLARE @categoryid INT = 8
DECLARE @DetailQuestionID INT = 1380
/*------- I need the query to run for the below three data.
Here i'm updating my planids that already exists in my database*/

I am trying to use a stored procedure to update a column in a sql table using the value from a variable table I getting errors because my syntax is not correct. I think table aliases are not allowed in UPDATE statements.
This is my statement:
UPDATE [dbo].[sessions_teams] stc
SET stc.[Talks] = fmt.found_talks_type
FROM @Find_Missing_Talks fmt
WHERE stc.sessionid IN (SELECT sessionid FROM @Find_Missing_Talks)
AND stc.coupleid IN (SELECT coupleid FROM @Find_Missing_Talks)
A heavily-selected database will be in an inconsistent state for several hours during a batch process. For that time, a database snapshot is created and accessed instead. To allow constant client read access to the database, a database that only contains synonyms exists. Those synonyms point to the main database except during the batch process, at which time they point to the database snapshot.
To switch the synonyms, each synonym is dropped and then created pointing to the database snapshot (after its creation, of course). The drop/create occurs inside a transaction. Roughly, the SQL looks like this:
SET XACT_ABORT ON;
BEGIN TRANSACTION;
DROP SYNONYM [dbo].[some_proc];
CREATE SYNONYM [dbo].[some_proc] FOR [snapshot_db].[dbo].[some_proc];
GRANT EXECUTE, SELECT ON [dbo].[some_proc] TO public;
COMMIT TRANSACTION;
When the batch update is completed, the process is reversed with "snapshot_db" replaced with "regular_db". The SQL snippet above is dynamic SQL. What I've pasted is the dynamic SQL that is executed as a single batch.
While this switch is happening, clients are accessing the procedures through the synonyms, potentially at a high request rate. Testing reveals that clients can get the error:
Error=-2147217900, Id=0, Meaning=IDispatch error #3092,
Source=Microsoft OLE DB Provider for ODBC Drivers,
Description=[Microsoft][ODBC SQL Server Driver][SQL Server]Could not find stored procedure 'dbo.some_proc'.
This error only occurs once. If the same SPID retries its request and the transaction has not completed (for testing, a delay was added), then it blocks until the transaction completes.
Any way to prevent it besides a client-side retry?
I have a temptable with a list of user IDs that I want to drop so I created a script to do a cursor and run through my drop functions. The drops work by themselves and the ver check works with them but when I wrap them in the cursor all i get is an output for each user in the results window in ssms. why it's not setting the variable and instead outputting to results?
DECLARE @ver nvarchar(128);
DECLARE @UserName nvarchar(50);
DECLARE @UserD nvarchar(80);
DECLARE @LoginD nvarchar(80);
-- Initialize the variable.

I would like to change a value after the table updates inserts a new row based on the value of that column

My current proc updates(updates using joins of two or three tables) millions of records as per the condition provided for each department.
However, when the proc fails it writes to a ErrorTable, ERROR_MESSAGE(), ERROR_SEVERITY() and which department has failed.
Since the records are updated keeping the selected departments in loop, I get the department in a temp variable.
Now, I was asked to log the specific record where the failure was occured.
Something like log the identity column value or primary key value which record has failed.
If Exists ( Select c.name from sys.columns c where object_id = object_id('HH835HP') and C.name = 'ID_1' )
Begin
UPDATE HH835HP
SET ID_1 =
( select ROW_NUMBER() OVER(ORDER BY CHKDTS ASC) AS ID_1 FROM HH835HP ) ;
End;
Obviously... The stuff inside the IF is wrong syntax...I mean
UPDATE HH835HP
SET ID_1 =
( select ROW_NUMBER() OVER(ORDER BY CHKDTS ASC) AS ID_1 FROM HH835HP ) ;
I have a table with a identity column in sql server 7 database. Now i need to update this identity column. Directly i couldn't able to update this column since it is an identity column. So, i like to drop this identity nature first and then update it is easy to update it. For this purpose, I need a Transact-sql script. Please Let me know if you have any thoughts on this. Thanks.

When I drop a table should I also drop it's FK ? or they keys are removed with the table?
View 2 Replies View RelatedBackground:
I have a table (named achtransactions) that has 618,423 rows. I have the ID field set as the Primary Key.
Problem:
Usually when doing a single, simple update (ie: UPDATE achtransactions SET transstatus = 'APPROVED' where id = 123456) it would take less than a second.
All of a sudden, beginning today, the same UPDATE statement is taking about 20 seconds on average. Other smaller tables (~100 rows) update instantly, just appears to be this one table.
Any ideas on what I should look at to find the problem?
Thanks in advance,

All is happened when a server crashed some weeks ago and it was removed from my network. After that, under my SQL Server 2012 I get an orphaned account which cannot be removed. This account is a computer account related to an old SCOM installation.
If I try to execute the command DROP USER [NETWORKSERVERNAME$] I get the following error message:
The database principal has granted or denied permissions to objects in the database and cannot be dropped. Msg 15284, Level 16, State 1, Line 1
The database principal has granted or denied permissions to objects in the database and cannot be dropped.But if I run the following command to know all permission granted to the account, I get an empty result:
select * from sys.database_permissions where grantee_principal_id = user_id ('NetworkSERVERNAME$');
Furthermore, following the instructions provided by the official KB for troubleshooting orphaned users, I get another error [URL].

Msg 15291, Level 16, State 1, Procedure sp_change_users_login, Line 114
Terminating this procedure. The User name 'NetworkSERVERNAME$' is absent or invalid.
The only thing I can retrieve is 15 permissions that this account granted to another account in the past:

The error message is "cannot drop the table because it is being used for replication"
my sql version is in sql server 2012 and Im ussing merge replication.
I want to drop only one table.
I have a VIEW which is dynamically generated through complex dynamic SQL. Unfortunately the dynamic SQL uses "Select * from table" to select the columns because the programmer did that to reduce the amount of code in the dynamic SQL string as the code can't be debugged if it's too long.
Therefore, I have a VIEW with columns in it I don't need, and want to remove them from the view - I need to remove all columns with column names matching the syntax '%1%_2' .
The view is called TEMP_EXPORT_1
I can either use the code below to return a list of columns that I want removed:
select column_name from information_schema.columns
where table_name='TEMP_EXPORT_1' and column_name like '%1%_2'
Or I can use the code below to return the list of columns that I want to keep:
select column_name from information_schema.columns
where table_name='TEMP_EXPORT_1' and column_name not like '%1%_2'
Now how would I go about altering TEMP_EXPORT_1 view so that it no longer has these columns? I know views don't have a drop statement...
Therefore I tried the following but I'm not sure of the syntax:
ALTER VIEW dbo.TEMP_EXPORT_1
AS
SELECT (select column_name from information_schema.columns
where table_name='TEMP_EXPORT_1' and column_name not like '%1%_2')
FROM dbo.TEMP_EXPORT_1
Am I on the right track? how can I ALTER this view to remove these columns? ... I want to keep this separate from the code that generated the view as I want it as an optional procedure that can be run if needed.
Does anyone know why this does not work?
