I have a After insert, update trigger. When I update multiple records with unique constraints column in it update fails. But if this a single record update it works.
Could like to know the reason.
hello .
i have a grid for a table that gets updated with recordset.updatebatch
for a multi-user application.
the problem is that some of the table fields have to be unique
now imagine the next situation.
user A opens the form
user B opens the form
user A writes '1000' in the unique field
user A saves the recordset with updatebatch
user B writes '1000' in the unique field
user B saves the recordset with updatebatch
now there will be two records with the field '1000' !
how can i avoid this ?
i cannot check for unique during the update event of the grid
because it should check during the time it is saving and not
when it is just entering data without having updated the recordset
thanks !
I have two tables that can be created with sample data using the DDL at the bottom of this post. What I'm looking to do is update the QtyReceived column in tblPurchaseOrderLineDetail from the Qty column in tblReceivedItems. However, the tricky part that I can't figure out is splitting these quantities out over multiple lines. I should only be allowed to receive up to the QtyOrdered column in tblPurchaseOrderLineDetail.
For a specific example from the sample data we'll look at PurchaseOrderDetailID 28526. From the tblReceivedItems, there are three records with quantities of 48, 48, and 20. From the tblPurchaseOrderLineDetail there are three records of QtyOrdered of 55, 45, and 20. What I would like to happen is fulfill the records in the tblPurchaseOrderLineDetail sequentially (essentially in order of ExpectedDate). So, the QtyReceived would be 55, 45, and 16 for the corresponding records. If there is already a quantity in the QtyReceived column, but it's less than the QtyOrdered column, the quantity needs to be added to the column (not overwritten).
DDL To CREATE Sample Tables and Data:
CREATE TABLE [dbo].[tblReceivedItems](
[ID] [int] IDENTITY(1,1) NOT NULL,
[PurchaseOrderDetailID] [int] NULL,
[Qty] [int] NULL)
SET IDENTITY_INSERT [dbo].[tblReceivedItems] ON
INSERT [dbo].[tblReceivedItems] ([ID], [PurchaseOrderDetailID], [Qty]) VALUES (1, 28191, 48)
[code]....
This index is not unique

I know this is probably a flick of a switch but I cannot figure out which switch. Setup is SQL Server / Stored Procedures / DAL / BLL(skipped for testing) / PL. The stored procedure queries from only one table and two columns are ignored because they are being phased out. I can run the stored procedure and preview the data in the DAL but when I create a page with an ODS linked to the DAL and a GridView I get this error. I checked every column that does not allow nulls and they all have values. I checked unique columns (ID is the only unique and is Identity=Yes in the table definition). I checked foreign-key columns for values that are not in the foreign table and there are none. Any ideas why do I get this?
Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.
Hi,
I am getting the above error when trying to load a report into my Web Application, I have tracked the error down to one specific field in my database. Even though this field is a NVarChar field and is of size 30 it would seem that there is an issue returning the value from the field. I can write it into the database no problems but when I try to get it out of the database it returns the above error.
e.g
MOB 401.908.804 - Fails
0401.907.324 - okay
8239 9082 (pager) - fails
Anyone got an idea on how to fix this????
Regards..
Peter.
writing the query for the following, I need to collapse the continuity. If the termdate for an ID is one day less than the effdate of the next id (for the same ID) i need to collapse the records. See below example .....how should i write the query which will give me the desired output. i.e., get min(effdate) and max(termdate) if termdate is one day less than the effdate of next record.

I'm fairly new in SQL. Been trying for months to create the right script for this particular case but still cannot give me 100% result as required.
SCENARIO :
I am required to query from 2 tables for those unique record that meets both conditions below:-
1. Status is 1 @ max (trans_id), paychnl = CC
2. Status is 2 @ max (trans_id), paychnl = A or B
FYR, 2 tables and respective columns to query are as below:-
table PTFF --> col ID, TRANS_ID,TRANSDATE,EFFDATE,TRANSCODE
table CHFF --> col STATUS,PAYCHNL
FYI, status refers to the paychnl method status:-
==> 1 means the current paychnl method
==> 2 means the previous paychnl method
paychnl method can be multiple because it will be defined as 2 for all the histories' paychnl chosen earlier, but 1 should only be unique as it is the latest paychnl chosen for each unique ID. however, it may appear more than once when it's taking those in earlier TRANSDATE, so here we would need the max trans_id as it will show the latest updated TRANSDATE.
Apart from that, I need only those most recent paychnl to be A or B and the latest paychnl is CC so, this been indicated by the same max trans_id for the same ID.
Aft trying so many times on this MAX command but failed to get any result, I only managed to come up to this part only. please refer below:-
table PTFF --> col ID, TRANS_ID,TRANSDATE,EFFDATE,TRANSCODE
table CHFF --> col STATUS,PAYCHNL
SELECT DISTINCT PTFF.TRANSCODE,PTFF.ID,PTFF.TRANS_ID,PTFF.TRANSDATE,PTFF.EFFDATE, CHFF.STATUS,CHFF.PAYCHNL
FROM DBO.PTFF PTFF
JOIN DBO.CHFF CHFF
ON CHFF.ID = PTFF.ID
WHERE
PTFF.TRANSDATE BETWEEN 130501 AND 130831
AND PTFF.TRANSCODE='T522'
AND (CHFF.STATUS=1 AND CHFF.PAYCHNL='CC' OR (CHFF.STATUS=2 AND (CHFF.PAYCHNL='A' OR CHFF.PAYCHNL='B')))
However, the script above returns :-
1. All those records with STATUS 1 regardless paychnl is A or B in most recent status 2,
2. Expected results also appear ==> 1 same ID with status 1 while paychnl=CC and status 2 while paychnl=A or B
3. Also duplicates of expected results but for different TRANSDATE and not at MAX TRANS_ID
Samples of the result:-

I'm new to MS SQL and VB. I have a table with one field JOB_NAME containing 20 records. Out of that field I want to retrieve 6 of the 20 records into a pulldown menu. They are all unique text names like so:
Anna Smith
John Doe
etc. I did not see IDs listed for any of the names in the table when I looked.
There is no common denominator to the names that can be filtered in the SELECT statement, and the 6 that I want will need to be pulled out individually.
Is there a way to do this with a SELECT statement? I have not found much information about how to extract unique records out of a single field. Here's the statement I'm using which pulls all of them:
strSQL = "SELECT DISTINCT JOB_NAME AS Names FROM [WORKER_NAMES] WHERE JOB_NAME<>' ' ORDER BY JOB_NAME ASC"
This gives me the total list but I only want to bring back 6 of the 20 for the pulldown.
Is there a way to modify this statement to pull only the records that I want?
Thanks for any help you can give.

hi team,
.Can i create umique constraint with out unique index.when i am creating a unique constraint sql creates a unique index (default) can i have only unique constraint ?
Look at the following code,
Create table #test
(
id int primary key,
Name varchar(100)
)
insert into #test values (1,'John')
insert into #test values (2,'Walker')
[Code] ....
-- Query 1 :
update #test set name = 'Joney' where id = 1
-- Query 2 :
set rowcount 1
update #test set name = 'Joney' where id = 1
set rowcount 0
1. #test table have primary key & clustered index.
2. Obviously only one row will be available for an id.
3. In query 1, will the sql server look for matching rows even after it found 1 row?
4. Will query 2 really gains some performance?
I have a messy design that I can't change but need to keep in synch. I have a master table where a person's info is entered into. Upon that entry I have to take that info (name, bdate,ssn,location) and populate it to 4 separate tables in 4 separate databases, all of which have their own id field which has to be incremented (no none of them are identity columns). At the end of the process I have to update the master record with the id fields of all the other four tables. I was going to do this with an insert trigger. As far as protecting the id's across all four databases, I was going to use a begin trans and get the next id field for all four databases and then apply the logic to add the records. Does this seem a safe approach, or am I missing something? Do I need to do a begin tran for each database separately?
THanks
I have an address table, and a log table will only record changes in it. So we wrote a after udpate trigger for it. In our case the trigger only need to record historical changes into the log table. so it only needs to be an after update trigger.The trigger works fine until a day we found out there are same addresses exist in the log table for the same student. so below is what I modified the trigger to. I tested, it seems working OK. Also would like to know do I need to use if not exists statement, or just use in the where not exists like what I did in the following code:
ALTER TRIGGER [dbo].[trg_stuPropertyAddressChangeLog] ON [dbo].[stuPropertyAddress]
FOR UPDATE
AS
DECLARE @rc AS INT ;
[code]....
I have the following trigger that updates a couple test fields to null when they are 1/1/1900, works great on inserts, and one line updates:
CREATE TRIGGER UpdateDate
ON test
AFTER INSERT, UPDATE
AS
UPDATE Test
SET
[CheckDate] = CASE WHEN [CheckDate] = '19000101' THEN NULL ELSE [CheckDate] END,
[CheckDate2] = CASE WHEN [CheckDate2] = '19000101' THEN NULL ELSE [CheckDate2] END
where AutoID = (select AutoID from inserted)
However, when trying to do a multi line update statement, I get the following error:
Msg 512, Level 16, State 1, Procedure UpdateDate, Line 7
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.The statement has been terminated
How can I get around this?
I need to ensure that each record in a table is unique in terms of two fields. E.g. Job No. 1 and Phase 1 cannot exist twice. I've tried to achieve this using a compound primary key but am having no joy. Im sure its a simple issue, any suggestions?
Thanks
Alex
I have a table which when certain columns are updated, need a trigger to fire to update a next schedule date in that same table for that record. I can write the trigger, but my question for performance and efficiency is which approach would be better. Separate triggers fo the 8 columns, or a large trigger with an If to check if these columns are updated.
Thanks
Hello, I want to write a unique constraint that applies to more than one column. What I mean is that the uniqueness should be that if column A is 5 and column B is 3 no other row where A and B has those values can exist.
Do I write this as a check constraint ? Or how do I do it ?
Also, is there anyone who knows some good reading on how to use Link Tables (many to many relations) in MS SQL Server ?
We have an UPDATE trigger that is failing. This seems like a basic task - we want to write a record to a separate tracking table when our main transaction table is updated for any reason. Our assumption is that we have a reference to the data from the "inserted" record that was just updated. The scenario here is that we are running a batch process which READS several thousand records in our transaction table each evening.
We then mark each individual record as processed on the transaction table and expect that the UPDATE trigger will successfully fire (it is not). The version of our trigger listed below shows our attempt to deal with the fact that TransactionID does NOT exist from "inserted." We also have a version of this trigger that deals with INSERTS - it works flawlessly.
ON [dbo].[FPS_Transaction]
AFTER UPDATE
AS declare @trxId uniqueidentifier;
BEGIN TRY
SET NOCOUNT ON

Hello,
Anyone know how to create an update trigger where the primary key isn't fixed.
If the primary key change how can I tie together the Deleted and Inserted tables if more than one row is updated?

Can anybody help me with specifing a UNIQUE Constraint when creating a table in enerprise manager?
View 1 Replies View RelatedI have one table like below Test table. My requirement is to create constraints to confirm <g class="gr_ gr_331 gr-alert gr_gramm Grammar only-ins replaceWithoutSep" data-gr-id="331" id="331">uniqueness</g> of STID value 101 with LN.
like
ID - LN - STID
1 - 'ABC' - 101 ---- Valid Row
2 - 'ABC' - 202 --- Valid Row
3 - 'ABC' - 202 --Valid Row (as I want only unique when LN = 'ABC' with STID = 101)
4 - 'ABC' - 101 -- Invalid Row (As I want uniqueness base on LN and STID = 1011)
create table dbo.Test
(
ID int identity,
LN varchar(50),
STID bigint

Is this possible with constraints as I don't want to use <g class="gr_ gr_1041 gr-alert gr_gramm Grammar only-ins doubleReplace replaceWithoutSep" data-gr-id="1041" id="1041">trigger</g>.
I am in the "Check Constraints" window trying to add a constraint that during inserts only allow distinct Column2 insertions. What is the Expression for that? I tried UNIQUE(Column2) it give me an error.
Here is my table definition:
Column Name Data Type Allow Nulls
--------------------------------------------------------------------------------------------
Column1(PrimaryKey) int No
Column2 nvarchar(MAX) No
I have two tables called ECASE and PROJECT
In the ECASE table there is trigger to get the max value of case_id column in ecase based on project and increment one to that case_id value and insert into ecase table .
When we insert a new record to the ECASE table this trigger calls and insert the case_id column value.
When i run with multiple threads , the transaction is rolled back because of trigger . The reason is , on the project table the lock is happening while getting the max value of case_id column based on project.
I need to prevent the deadlock .
I would like to change a value after the table updates inserts a new row based on the value of that column
Table Name is: MPanel
Col Names: RID, FPID.
I want to:
If column RID='16'
Then UPDATE FPID='1'
How can I trigger that update? Would this work:???
CREATE TRIGGER dbo.MyTrigLI
ON dbo.MPanel
FOR INSERT, UPDATE
AS
BEGIN
UPDATE [MPanel]
SET
FPID='1'
WHERE (UPDATE(RID='16')
END
I am writing a trigger for getting values to auditlog table when the values gets updated. Below is the code of my trigger.
CREATE TRIGGER [dbo].[Update_Temp] ON [dbo].[Temptable1] FOR UPDATE
AS
DECLARE @bit INT ,
@field INT ,
@maxfield INT ,
@char INT ,
@fieldname VARCHAR(128) ,
@TableName VARCHAR(128) ,
[Code] ....
The code is working fine when the table has primary key associated. However due to some restrictions I will not be able to have a primary key for some tables. I want to implement the same trigger in those tables too. When there is primary key, that primary key needs to get inserted into the audit table and if there is no primary key, i want a specific column value to get inserted instead of the primary key value into the audit table.
For example, i have a student table in which there is a student id, name, dob. there is no primary key defined for the table. So when i update the name or dob, i need the student id to get inserted into the Pk column of the audit table.
I tried modifying the code by checking the @pkcols for Null and if its null to get the old value as the primary key however I was not able to do it .
Got a beginner question here...
Let's say I have a database table that houses server information with four columns: make, model, serial #, ip address. And assume there are ten rows with that information filled out. How could I display all the rows of information on a single webpage (ASP.NET), with all the fields being editable; and a single save button that would send any changes to the database (in reality I guess it would be sending all rows and fields to the database, and just overwrite the previous data).
Could a page such as that be created using FrontPage 2003 or Dreamweaver MX 2004?
This would be strictly for updating information. I would have a separate form for adding a new entry.
Thanks for your help.
I have an 'update' query that looks like this:
update wce_contact
set blank = 'missing'
where website in ('www.name1.co.uk','www.name2.co.uk','www.name3.co.uk')
I know this query will set 'blank' to missing when it matches the above websites. However if i wanted to set blank to 'missing' where mail1date is not null and mail2date is not null (keep going to mail18date not null) how exactly would i go about this?
I guess it would be a case of adding another bracket somewhere but im unsure?
Hi All,

e.g If original database is

2 3
3 6

I need to update more than one record at once. I have ~ 100 records that I have to update and don't want to execute query 100 times.
My query looks like this:
Update Table1
Set Table1.field1 = ( select Table2.field1 from Table2 where Table2.field2 IN ('a', 'b', 'c')
where Table1.field2 IN ( 'a', 'b', 'c')
It obviously failed because subquery returned more than one value and error message stated that I can't use '=' operator in this case.
My question: how could I update the same column from many records in one execution?

I am renovating an existing application and am converting the existing passwords into hashed values using SHA1. I know how to compute the hashed values as a byte array for each record. What I don't know how to do easily is update all of the records i a single call to the database. Normally, I would just do the following:UPDATE HashedPassword = someValue WHERE UserID = 101;
UPDATE HashedPassword = someOtherValue WHERE UserID = 102;
...
What I don't know is what someValue and someOtherValue should be. How do I convert my byte array into string representation that SQL will accept? I usually execute multiple statements using Dim oCmd as New SqlCommand(sSQL, MyConn) and then call oCmd.ExecuteNonQuery().
Alternatively, I found the following code that uses the byte array directly but only shows a single statement. How could I use it to execute multiple statements as shown above?'FROM http://aspnet.4guysfromrolla.com/articles/103002-1.2.aspx
