DB Engine :: Can't Use The MERGE Statement / How To Design WHERE Condition For Insert Statement
Nov 5, 2015
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.
This website describes how Merge statements should be optimized by the use of indexes on the target?source tables: [URL]..... It says that a clustered index should be created on the join column in the target and a unique covering index on the source table.
I have read in other articles that insert/delete/update statements perform worse on tables with clustered indexes as the leaf level pages will have to be reorganized.
Why in the case of Merge statement having a indexes actually improve the performance of insert/delete/update statements?
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 get this error when inserting data..The INSERT statement conflicted with the FOREIGN KEY constraint FK_Participant_ Log_BiometricInstance_ Participant_ Activities". The conflict occurred in database "ProvantCustomerPortal", table "dbo.Activities", column 'Id'.The statement has been terminated.
My query looks like this :
insert into [dbo].[Participant_BiometricInstance](ParticipantId, ActivityId, ProviderTypeId, Fasting, ExternalSystemId, ResultsDate, ModifiedBy, ModifiedDate) select participantID,'','','',NULL,getdate(),NULL,getdate() from [dbo].[Participant_Profile]
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?
Can we insert into multiple table using merge statement?I'm using SQL Server 2008 R2 and below is my MERGE query...

Hi All, I've looked through the forum hoping I'm not the only one with this issue but alas, I have found nothing so I'm hoping someone out there will give me some assistance. My problem is the case statement in my Insert Statement. My overall goal is to insert records from one table to another. But I need to be able to assign a specific value to the incoming data and thought the case statement would be the best way of doing it. I must be doing something wrong but I can't seem to see it.
Here is my code: Insert into myTblA (TblA_ID, mycasefield = case when mycasefield = 1 then 99861 when mycasefield = 2 then 99862 when mycasefield = 3 then 99863 when mycasefield = 4 then 99864 when mycasefield = 5 then 99865 when mycasefield = 6 then 99866 when mycasefield = 7 then 99867 when mycasefield = 8 then 99868 when mycasefield = 9 then 99855 when mycasefield = 10 then 99839 end, alt_min, alt_max, longitude, latitude ( Select MTB.LocationID MTB.model_ID MTB.elevation, --alt min null, --alt max MTB.longitude, --longitude MTB.latitude --latitude from MyTblB MTB );
The error I'm getting is: Incorrect syntax near '='.
I have tried various versions of the case statement based on examples I have found but nothing works. I would greatly appreciate any assistance with this one. I've been smacking my head against the wall for awhile trying to find a solution.
Select DOJ AS 'JoiningDate' from emp where DOJ like '%2008/09/04%'
there are 8 records on this time.But it displays no result . The column is datetime datatype year month date or we need to mention any thing other than this.
Can you implement the same type of feature in SQL as MS Access uses with it's "immediate if" or iif() function? In other words can you look at a specific row and change the contents of one field based on the contents of another field in the same row?
I am trying to create a view like the the following:
CREATE VIEW AS Test SELECT name, city , IF city = 'NY' state ELSE country FROM address_table
The view's 3rd field will be either [state] or [country] depending on the contents of [city]
Hi All, I want get the result in a single SELECT statement
SELECT SUM (PAID_LOSS), SUM (PAID_EXP) GROUP BY COMPANY FROM VIEW_POLICY WHERE Accounting_Period GE 200701 and LE 200712 -************************************ SELECT SUM (MEDICAL_RESERVE) GROUP BY COMPANY FROM VIEW_POLICY WHERE Accounting_Period LE 200712
36930.60 145 N . 00 17618.43 190 N . 00 6259.20 115 N .00 8175.45 19 N .00 18022.54 212 N .00 111.07 212 B 100 13393.05 67 N .00
In above 4 col
if col3 value is B then cursor has to fectch appropriate value from col4. if col3 value is N then cursor has to fectch appropriate value from col1. and also wants the sum of result above conditions when column 3 has two values(i.e N,B) for single col2 value
here col2 values are unique
take an example for col2=212 if col3=B then result is 100 if col3=N then result is 18022.54 for a single col 2 value ,if col3= N and B then we want sum of above 2 conditions i.e (100+18022.54) but not the sum of (100+18022.54+111.07+0.0) .
I tried following code and it return no data after query run successfully. I m testing it on msaccess .
SELECT Book.ID, Book.Title, Book.Arthor, Book.Publisher, Book.Year, Book.Price, Inventory.B_ID, Inventory.Quantity FROM Book INNER JOIN Inventory ON Book.ID=Inventory.B_ID WHERE Book.ID=Inventory.B_ID And ("Book.Arthor" Like '%es%');

I have test and test2 in Arthor column ... Thanks all !!
I've found that there is no such thing as a Case Statement in the Derived Column task in the data flow objects. I've written a ternary statement instead. I can't seem to get it to work exactly how I want it to. For example
The CreditAmount and DebitAmount Fields are spelled correctly, the field type of AccountCategory is String and the Field type of CreditAmount and DebitAmount is numeric, but that seems to be the same situation that I have in the first example that works. Am I missing something? I'd appreciate any advice anyone has to offer. Thanks,
Update WACTS_Inventory_Part_Loc_Tbl SET WIPLT_Part_New_Qty = WIPLT.WIPLT_Part_New_Qty + tmp.MATIN_QTY FROM
WACTS_Inventory_Part_Loc_Tbl WIPLT
INNER JOIN
Temp_MatIn_Data tmp
ON
WIPLT.WIPLT_Part_Number_MSBA=tmp.PARTS_ShortID
WHERE
WIPLT.WIPLT_Location_Code='MF'
I have a Problem with this satment becoz my Temp_Matin_Data_Tmp table contains two records with the same PartNumber that is (ShortId) and the two records have two different quantities.
The WACTS_Inventory_Part_Loc_Tbl has only one Part NUmber Record and the key is the PartNUmber and Location_Code.
Now when the Update Satement runs it updates the qty only from the first record of the temp table and does not update the quantity of the second record from tne source table.
I have 20 rows in dbo.test so i will get 20 as my output, now i need to write a case statement here such that when count(*) = 0 then it should display text filed 'NO Data' else it should display the count.

I want to change Set clause of Update Statement dynamically based on some condition.
Basically i have 2 Update statments having same FROM clause and same JOIN clause.
Only diff is SET clause and 1 Where condition.
So i am trying to combine 2 Update statements into 1 and trying to avoid visit to same table twice.
Update t Set CASE **WHEN Isnull(td.IsPosted, 0) = 0 THEN t.AODYD = td.ODYD** *ELSE t.DAODYD = td.ODYD* END From #ReportData As t Join @CIR AS tmp On t.RowId = tmp.Max_RowId
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'."
Hi All,I have a database that is serving a web site with reasonably hightraffiic.We're getting errors at certain points where processes are beinglocked. In particular, one of our people has suggested that an updatestatement contained within a stored procedure that uses a wherecondition that only touches on a column that has a clustered primaryindex on it will still cause a table lock.So, for example:UPDATE ORDERS SETprod = @product,val = @valWHERE ordid = @ordidIn this case ordid has a clustered primary index on it.Can anyone tell me if this would be the case, and if there's a way ofensuring that we are only doing a row lock on the record specified inthe where condition?Many, many thanks in advance!Much warmth,Murray
Could a simple update statement on a user database ever caused space usage in tempdb? Assuming the update statement fires no triggers and not using any temp tables?
IE:
User DatabaseA Update TableX Set col1 = X
Reason I ask is tempdb filled up and the only thing I could see running at that time was the update statement.
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.
