In the following t-sql 2012 merge statement, the insert statement works but the update statement does not work. I know that is true since I looked at the results of the update statement:
Merge TST.dbo.LockCombination AS LKC1 USING (select LKC.comboID,LKC.lockID,LKC.seq,A.lockCombo2,A.schoolnumber,LKR.lockerId from [LockerPopulation] A JOIN TST.dbo.School SCH ON A.schoolnumber = SCH.type
[Code] ...
Thus can you show me some t-sql 2012 that I can use to make update statement work in the merge function?
I have created a Dynamic Merge statement SCD2 Store procedure , which insert the records if no matches and if bbxkey matches from source table to destination table thne it updates old record as lateteverion 0 and insert new record with latest version 1.
I am getting below error when I ahve more than 1 bbxkey in my source table. How can I ignore this.
BBXkey is nothing but I am deriving by combining 2 columns.
Msg 8672, Level 16, State 1, Line 6
The MERGE statement attempted to UPDATE or DELETE the same row more than once. This happens when a target row matches more than one source row. A MERGE statement cannot UPDATE/DELETE the same row of the target table multiple times. Refine the ON clause to ensure a target row matches at most one source row, or use the GROUP BY clause to group the source rows.
2 Users in 2 locations issue updates to the same table. 1 updating 1 column and the other updating another column. Now in reality the actual Stored Procedure issuing the update statement is passed in all the possible columns that could change and builds an update statement that updates all columns even the ones that havent changed.
Will this break Merge Replications conflict tracking? Or does SQL Server 2005 Merge Replication pickup that in reality the 2 updates only in reality changed the values in 2 columns.
Problem Summary: Merge Statement takes several times longer to execute than equivalent Update, Insert and Delete as separate statements. Why?
I have a relatively large table (about 35,000,000 records, approximately 13 GB uncompressed and 4 GB with page compression - including indexes). A MERGE statement pretty consistently takes two or three minutes to perform an update, insert and delete. At one extreme, updating 82 (yes 82) records took 1 minute, 45 seconds. At the other extreme, updating 100,000 records took about five minutes.When I changed the MERGE to the equivalent separate UPDATE, INSERT & DELETE statements (embedded in an explicit transaction) the entire update took only 17 seconds. The query plans for the separate UPDATE, INSERT & DELETE statements look very similar to the query plan for the combined MERGE. However, all the row count estimates for the MERGE statement are way off.
Obviously, I am going to use the separate UPDATE, INSERT & DELETE statements. The actual query plans for the four statements ( combined MERGE and the separate UPDATE, INSERT & DELETE ) are attached. SQL Code to create the source and target tables and the actual queries themselves are below. I've also included the statistics created by my test run. Nothing else was running on the server when I ran the test.
Server Configuration:
SQL Server 2008 R2 SP1, Enterprise Edition 3 x Quad-Core Xeon Processor Max Degree of Parallelism = 8 148 GB RAM
SQL Code:
Target Table: USE TPS; IF OBJECT_ID('dbo.ParticipantResponse') IS NOT NULL DROP TABLE dbo.ParticipantResponse;
I've have a need with SQL Server 2005 (so I've no MERGE statement), I have to merge 2 tables, the target table has 10 fields, the first 4 are the clustered index and primary key, the source table has the same fields and index.Since I can't use the MERGE statement (I'm in SQL 2005) I have to make a double step operation, and INSERT and an UPDATE, I can't figure how to design the WHERE condition for the insert statement.
I do realize that his could be posted in a few spots but I think the answer is in the SQL. I have a ASP.NET page, with a SqlDataSource, Text Box and Calendar Controls. I have the textbox and calendar controls eval'ed to the same sql data source DateTime Field. The text box is formatted eval to small time and the calendars eval has no formatting. ex: <asp:TextBox ID="START_TIME" Text='<%# Eval("EVENT_START","{0:t}") %>' runat=server Width=200></asp:TextBox> I want to merge the two controls; one has the date the other has the time when I update the pages data to the SqlDataSource field EVENT_START. I've tried a couple of methods, but I would like some other opinions. As Sql server only supports date and time together I am storing the two together. I could merge the two together in the code behind on the update button's event handler or merge the two during the update query using parameters. Not that I could get an illegal date for the calendar control, but I could get garbage from the textfield time. So I still would have to do validation on the text field before the SQL server could do the update. There's a few ways to go about this, so I was wondering if anyone else has figured out an elegant way to handle it. wbochar
I am currently having this problem with gridview and detailview. When I drag either onto the page and set my select statement to pick from one table and then update that data through the gridview (lets say), the update works perfectly. My problem is that the table I am pulling data from is mainly foreign keys. So in order to hide the number values of the foreign keys, I select the string value columns from the tables that contain the primary keys. I then use INNER JOIN in my SELECT so that I only get the data that pertains to the user I am looking to list and edit. I run the "test query" and everything I need shows up as I want it. I then go back to the gridview and change the fields which are foreign keys to templates. When I edit the templates I bind the field that contains the string value of the given foreign key to the template. This works great, because now the user will see string representation instead of the ID numbers that coinside with the string value. So I run my webpage and everything show up as I want it to, all the data is correct and I get no errors. I then click edit (as I have checked the "enable editing" box) and the gridview changes to edit mode. I make my changes and then select "update." When the page refreshes, and the gridview returns, the data is not updated and the original data is shown. I am sorry for so much typing, but I want to be as clear as possible with what I am doing. The only thing I can see being the issue is that when I setup my SELECT and FROM to contain fields from multiple tables, the UPDATE then does not work. When I remove all of my JOIN's and go back to foreign keys and one table the update works again. Below is what I have for my SQL statements:------------------------------------------------------------------------------------------------------------------------------------- SELECT:SELECT People.FirstName, People.LastName, People.FullName, People.PropertyID, People.InviteTypeID, People.RSVP, People.Wheelchair, Property.[House/Day Hab], InviteType.InviteTypeName FROM (InviteType INNER JOIN (Property INNER JOIN People ON Property.PropertyID = People.PropertyID) ON InviteType.InviteTypeID = People.InviteTypeID) WHERE (People.PersonID = ?)UPDATE:UPDATE [People] SET [FirstName] = ?, [LastName] = ?, [FullName] = ?, [PropertyID] = ?, [InviteTypeID] = ?, [RSVP] = ?, [Wheelchair] = ? WHERE [PersonID] = ? ---------------------------------------------------------------------------------------------------------------------------------------The only fields I want to update are in [People]. My WHERE is based on a control that I use to select a person from a drop down list. If I run the test query for the update while setting up my data source the query will update the record in the database. It is when I try to make the update from the gridview that the data is not changed. If anything is not clear please let me know and I will clarify as much as I can. This is my first project using ASP and working with databases so I am completely learning as I go. I took some database courses in college but I have never interacted with them with a web based front end. Any help will be greatly appreciated.Thank you in advance for any time, help, and/or advice you can give.Brian
Hello, I have two tables: Orders and Appoitment. Each order can have up to 2 appointments. Now, I need a SELECT statement that gives me this:
ORDER APPT 1 appt1 appt2 2 appt1 appt2
and not this:
ORDER APPT 1 appt1 1 appt2 2 appt1 2 appt2
In other words, I want to merge the two appointments for each order. I tried using the merge statement but it does not work. Tried to google but saw nothing. My database is SQL server. Please help. Thanks
We have a current database table (PAF) that had a new column added to it named 'Email'. This table also has some other columns including one named [Employee Number].We also have an Excel spreadsheet that has 2 columns 'Employee Number' and 'E-mail Address'. I need to take the E-mail Address field from the spreadsheet, match it up with the employee number between the spreadsheet and PAF table, and then insert the email address into the database column.I'm guessing I would do this using a MERGE statement, correct?
I want to combine update and insert statement into single statement as follows.
MERGE INTO MyTable USING MyTempTable ON MyTempTable.MatchingField1 = MyTable.MatchingField1 WHEN MATCHED THEN UPDATE UpdateField1 = MyTempTable.UpdateField1 WHEN NOT MATCHED THEN INSERT VALUES(MyTempTable.MatchingField1, MyTempTable.UpdateField1)
Currently if I try to run this stmt, it gives error "Incorrect syntax near the keyword 'INTO'."
Ok I have a query "SELECT ColumnNames FROM tbl1" let's say the values returned are "age,sex,race".
Now I want to be able to create an "update" statement like "UPATE tbl2 SET Col2 = age + sex + race" dynamically and execute this UPDATE statement. So, if the next select statement returns "age, sex, race, gender" then the script should create "UPDATE tbl2 SET Col2 = age + sex + race + gender" and execute it.
i was tasked to created an UPDATE statement for 6 tables , i would like to update 4 columns within the 6 tables , they all contains the same column names. the table gets its information from the source table, however the data that is transferd to the 6 tables are sometimes incorrect , i need to write a UPDATE statement that will automatically correct the data. the Update statement should also contact a where clause
the columns are [No] , [Salesperson Code], [Country Code] and [Country Name]
i was thinking of doing
Update [tablename] SET [No] = CASE WHEN [No] ='AF01' THEN 'Country Code' = 'ZA7' AND 'Country Name' = 'South Africa' ELSE 'Null' END

It appears to update only the first qualifying row. The trace shows a row count of one when there are multiple qualifying rows in the table. This problem does not exist in JDBC 2000.
Hi, I feel like this should be fairly simple but I just can't seem to get it! I basically want to update multiple records using a sub-query.
I have two tables: objects and temp1. Both have identical column names: Un_ID and SerialNum (one has serial numbers while the other has mostly Null values for the serial numbers). I want to update the SerialNum column in "objects" with the SerialNum column from temp1. The two tables can be linked by un_id's.
Here is my update statement: UPDATE Objects SET SerialNumber = (SELECT SerialNumber FROM temp1) WHERE (objects.Un_ID = temp1.un_id) The error I receive says "column prefix "temp1" does not match a table name or alias name used in the query".
I think the step I am missing is actually liking the two tables in the update statement. Can anyone help?
I'm writing a fairly involved stored procedure. In this Stored Procedure, I have an update statement, followed by a select statement. The results of the select statement should be effected by the previous update statement, but its not. When the stored procedure is finish, the update statement seemed to have worked though, so it is working.
I suspect I need something, like a GO statement, but that doesnt seem to work for a stored procedure. Can anyone offer some assistance?
is there anyway i can merge select statement and insert statement together?
what i want to do is select few attributes from a table and then directly insert the values to another table without another trigger.
for example, select * from product and with the values from product, insert into new_product (name, type, date) values (the values from select statment)
i have a little question. Is it possible you can't perform an insert statement on a table wich is replicated with merge replication?
I set the replication up and everything works fine, but if i want to perfom an insert statement on the table, i get an error that the values i want to add aren't the same as the one in the table.
I know that merge replication creates a new column and I think that's the problem.
Can someone help me solve this or confirm that you can't perform an insert statement on a replicated table?
I have a stored procedure that runs (SQL Server 2012 (SP1) Standard Ed) daily and I never had any problem with this stored procedure. However, there is MERGE statement on the stored procedure and I see an error saying that the MERGE statement failed..Here are the stored procedure and error message:
-- FlushQueue CREATE PROCEDURE [dbo].[FlushQueue] (@RowCount as int = 10000) AS BEGIN SET NOCOUNT ON; SET XACT_ABORT ON;
[code]....
The MERGE statement attempted to UPDATE or DELETE the same row more than once. This happens when a target row matches more than one source row. A MERGE statement cannot UPDATE/DELETE the same row of the target table multiple times. Refine the ON clause to ensure a target row matches at most one source row, or use the GROUP BY clause to group the source rows. [SQLSTATE 42000] (Error 8672). The step failed.

skip locked records in a MERGE statement and output the list of skipped records.
Through the documentation, internet posts and testing, I believe it is NOT possible. MERGE acts like a single atomic DML statement, and therefore cannot avoid locked records.
I can use the READPAST hint, which will skip the row-locked records. However, it could actually insert duplicate keys in certain cases (as it is ignoring records, i would guess), which would not be acceptable.
I was using Type 2 for one of our Fact table.... and need to put a flag to know which one is the Current record... I couldn't able to figure how to implement logic in the merge statement... This is an example Query ....I was using like this for my fact table...
Basically I need to track CustomerName and City... So I need a Currentflag (Y) for latest record....
MERGE INTO [dbo].[TargetCustomer] AS TRG USING [dbo].[MyCustomers] AS SRC ON TRG.[CustomerID] = SRC.[CustomerID] AND TRG.[CustomerName]=SRC.[CustomerName] AND TRG.[City]=SRC.[City]
In a t-sql 2012 merge statement that is listed below, the insert statement on the merge statement listed below is not working. The update statement works though.
Merge test.dbo.LockCombination AS LKC1 USING (select LKC.lockID,LKC.seq,A.lockCombo1,A.schoolnumber from [Inputtb] A JOIN test.dbo.School SCH ON A.schoolnumber = SCH.type JOIN test.dbo.Locker LKR ON SCH.schoolID = LKR.schoolID AND A.lockerNumber = LKR.number

Thus would you tell me what I need to do to make the insert statement work on the merge statement listed above?
How to Insert,Update and delete through script without using merge.I have simple requirement of Deleting,Inserting and Update from one table to other table...Here is the Sample Data
CREATE TABLE #Table1 (ID INT ,Name VARCHAR(30),DATEKEY INT) INSERT INTO #Table1 (ID,Name,DATEKEY)VALUES (1,'Mohan',20131231) INSERT INTO #Table1 (ID,Name,DATEKEY)VALUES (2,'Raj',20131231) INSERT INTO #Table1 (ID,Name,DATEKEY)VALUES (3,'Majja',20131231) INSERT INTO #Table1 (ID,Name,DATEKEY)VALUES (4,'Majjaa',20131231)
[code]...
So now i need to update 1st record and add another new record..So i need to update as well as delete the existing data in Target table.
INSERT INTO #Table1 (ID,Name,DATEKEY)VALUES (5,'Macha',20131231)
My output should come like this one :
IDNameDATEKEY 1Mohan20131231 5Macha 20131231
with out using merge how can i handle Update,insert and Delete through TSQL
Hi, I'am using several SQL 2000 servers with different working merge-replications. Actually I wrote a .NET assembly which makes updates to key values in one of the replicated tables:
Ex: update ReplTable set key = -key where key between (1 and 100)
Loop ...... update ReplTable set key = NewKey where key = .... end of loop
Intention is to resort the datarows. So I made two updates to every keyvalue in a very short time. At the ConflictViewer I got messages like:
"The row was inserted at 'ServerX' but could not be inserted at 'ServerY'. Violation of PRIMARY KEY constraint 'PK_xxxx. Cannot insert duplicate key in object 'ReplTable'. "
The replication did only deliver one (the last) update - this makes the violation. Is there a possibility to make the mergeagent known that I wanted to deliver every transaction? Is there a parameter in the agents profile?
I have to load 2 flat file of 2 Gb each in a table. I found 2 ways to do that: - Either I read my 2 file in parallels and I use a merge join transformation to merge my data. Then I load theses datas in my destination table - Or I insert all my first file in the destination table then I read the second file and update my table with the new information.
Based on your experience, what is the best ? I'm running the first way for more than 30 minutes and SSIS is still sorting my datas.... (sort before the merge join)
I have 2 aspx pages. one is "login.aspx" and the second is "test_connection.aspx". the "login.aspx" is using the membership class for my website's security. if u have have restarted your computer and you first load this "login.aspx", this will work fine and you will see that you can create a user. when you load (or view) next "test_connection.aspx" you will get this error message:

If I will restart my computer and I will load first the "test_connection.aspx", this page will work just fine and if you will load next "login.aspx", i will get this error message:

what's happening? i cant understand. I dont know what im doing wrong. i am very new to this dotNET and MS-SQL. im not sure if this has relation to the other problem i have on the other thread (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=254568&SiteID=1).
I use the merge statement in a sproc to insert, update and delete records from a staging table to a production table.
In the long sql, here is a part of it,
When Matched and
((Student.SchoolID <> esis.SchoolID OR Student.GradeLevel <> esis.GradeLevel OR Student.LegalName <> esis.LegalName OR Student.WithdrawDate <> esis.WithdrawDate Student.SPEDFlag <> esis.SPEDFlag OR Student.MailingAddress <> esis.MailingAddress)
Then update
Set Student.Schoolid=esis.schoolid, .....
My question is how about if the column has null values in it.for example
if schoolID is null in production table is null, but in staging table is not null, will the <> return true.or if either side of <> has a null value, will it return true.
I don't want it to omit some records and causing the students records not get updated.If not return true, how to fix this?

We have a SSIS package which loads the data from csv files to DB. It only loads the new entries ie if the row already exists in the tables than it doesn't insert it. For this we load the CSV to temp tables for respective schemas and than those are compared with base tables of respective schemas and inserted new rows. For this we use Merge statement.
