View 4 Replies View RelatedMultiple Tables Used In Select Statement Makes My Update Statement Not Work?
Aug 29, 2006I 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

Jan 3, 2005hi!
I have a big problem. If anyone can help.
I want to retrieve the last update time of database. Whenever any update or delete or insert happend to my database i want to store and retrieve that time.
I know one way is that i have to make a table that will store the datetime field and system trigger / trigger that can update this field record whenever any update insert or deletion occur in database.
But i don't know exactly how to do the coding for this?
Is there any other way to do this?

Track The Changes To Normalised Tables And Update The Denormalised Tables Depending On The Changes To Normalised Tables
Dec 7, 2006We have 20 -30 normalized tables in our dartabase . Also we have 4tables where we store the calculated data fron those normalised tables.The Reason we have these 4 denormalised tables is when we try to dothe calcultion on the fly, our site becomes very slow. So We haveprecalculated and stored it in 4 tables.The Process we use to do the precalcultion, will get do thecalculation and and store it in a temp table. It will compare the thetemp with denormalised tables and insert new rows , delte the old oneans update if any changes.This process take about 20 mins - 60mins. Ittakes long time because in this process we first do the calculationregardless of changes and then do a compare to see what are changed andremove if any rows are deleted, and insert new rowsand update thechanges.Now we like to capture the rows/columns changed in the normalisedtables and do only those chages to the denormalised table , which weare hoping will reduce the processing time by atleast 50%WE have upgraded to SQL SERVER 2005.So We like to use the newtechnology for this process.I have to design the a model to capture the changes and updated onlythose changes.I have the list of normalised tables and te columns which will affectthe end results.I thought of using Triggers or OUTPUT clause to capture the changes.Please help me with the any ideas how to design the new process
View 3 Replies View RelatedMultiple Tables Select Performance - SQL 2005 - Should It Take 90 Seconds For A Select?
Dec 4, 2007I have a problem where my users complain that a select statement takes too long, at 90 seconds, to read 120 records out of a database.
The select statement reads from 9 tables three of which contain 1000000 records, the others contain between 100 and 250000 records.
I have checked that each column in the joins are indexed - they are (but some of them are clustered indexes, not unclustered).
I have run the SQL Profiler trace from the run of the query through the "Database Engine Tuning Advisor". That just suggested two statistics items which I added (no benefit) and two indexes for tables that are not involved at all in the query (I didn't add these).
I also ran the query through the Query window in SSMS with "Include Actual Execution Plan" enabled. This showed that all the execution time was being taken up by searches of the clustered indexes.
I have tried running the select with just three tables involved, and it completes fast. I added a fourth and it took 7 seconds. However there was no WHERE clause for the fourth table, so I got a cartesian product which might have explained the problem.
So my question is: Is it normal for such a type of read query to take 90 seconds to complete?
Is there anything I could do to speed it up.
Any other thoughts?
Thanks
Declaring A Table Variable Within A Select Table Joined To Other Select Tables In Query
Oct 15, 2007Hello,
I hope someone can answer this, I'm not even sure where to start looking for documentation on this. The SQL query I'm referencing is included at the bottom of this post.
I have a query with 3 select statements joined together like tables. It works great, except for the fact that I need to declare a variable and make it a table within two of those 3. The example is below. You'll see that I have three select statements made into tables A, B, and C, and that table A has a variable @years, which is a table.
This works when I just run table A by itself, but when I execute the entire query, I get an error about the "declare" keyword, and then some other errors near the word "as" and the ")" character. These are some of those errors that I find pretty meaningless that just mean I've really thrown something off.
So, am I not allowed to declare a variable within these SELECT tables that I'm creating and joining?
Thanks in advance,
Andy

Update 2 Tables At Once
Jul 18, 2007Hi,
I have 2 database tables with column "city". When I update one of these two I want to be updated all the records in the other table. For example:
In table "a", column "city" contains the record "NY"; in table "b", column "city" also contains the record "NY" several times. When I change "NY" to "New York" in table "a" I want that also in table to be changed all the records. The condition is not to use foreign key, but just the text of the records.
Any help would be appreciated,thanks.
Update SQL Tables
Jan 16, 2004I have an package that goes out and downloads information from an Informix Database. This Information needs to be replicated in another table. However I cant just delete and insert the information into the table, There are a number of clients updating from this table once a minute. How can I make SQL Serve 2000 update the information based on another sql table ( Sort of like a local replication?). Is there a simply query I can use or do I need to set up another packeage stored procedure. Right now the information is placed in a tempory table, the actual table needing to be updated is cleared of its data, and the information is moved. However this causes latency issues in my program. Also, since the Infromix query can take up to 30 seconds to complete, this leaves some of my users retrieving blank data.

Mar 4, 2005I have a sales table that has a customer_number, salesman_number and sales data (like item, quantity, etc), there is a customer table that has the customer_number, name, address, etc. and salesman_number, with the passign of time salesmen come and go and the customer service department is in charge of modifying the customer table and assign the new salesman number to them. All the previous sales have to be reasigned to this new salesman even though it wasnt him the one that sold the items (I know, I know, thats the way the company requieres it, this is an old system). Now to my question:
I have this select query that gives me the rows from table sales that have to be modified:
SELECT C.sales_rep,S.salesrep,S.*
FROMSALES AS S
INNER JOIN customer AS C
ONC.Active_Flag = 'A' AND
C.sales_rep != 'XXXX' AND
C.site_code = S.site_code AND
C.cust_no = S.cust_noAND
C.cust_sffx = S.cust_sffxAND
C.division = S.divisionAND
C.sales_rep != S.salesrep
WHERES.month = 2AND
S.year = 2005
ORDER BYC.sales_rep
I just want to know if my approach to convert this query from an update to a select is ok:
UPDATE SALES AS S
SET S.salesrep = C.sales_rep
INNER JOIN customer AS C
ONC.Active_Flag = 'A' AND
C.sales_rep != 'XXXX' AND
C.site_code = S.site_code AND
C.cust_no = S.cust_noAND
C.cust_sffx = S.cust_sffxAND
C.division = S.divisionAND
C.sales_rep != S.salesrep
WHERES.month = 1AND
S.year = 2004

Select From One DB - Update In Another
Jan 25, 2007Hi there.
I have two databases, one called PWALive and one called Portal-Live.
what I want to do is create an extract from Portal-Live of e-mail addresses and then use this date to update a table in PWALive.
Here are the relevant tables
Portal-Live
tblMUD(MUD_ID, MUD_clock, MUD_email ... )
PWALive
employee(employee_number, email_address ... )
Relationship: MUD_clock = employee_number
My sql statement for the extract from Portal-Live.tblMUD looks like this:
SELECTMUD_clock,
MUD_email
FROM tblMUD
WHEREMUD_email IS NOT NULL
AND MUD_clock IS NOT NULL
I want to then update the correct employee in PWALive.employee:
UPDATE employee
SET ... --Not entirely sure what to do here!
WHERE employee_number = MUD_clock
How can I do this in one sql sequence/is it possible?
As I understand it I can use CONNECT TO but Icant get that to work, let alone know how to link the update with the first sql statement.
Big thank you in advance

Need Update Of Select Using TOP 1
Sep 21, 2006I need to update a table as follows:
Update item1, item2, item3, item4 in a table where column1="email_address" and column2 is ordered acending so the most recent entry for a specific user is updated.
column2 is a time stamp.
Pseudo code something like this:
UPDATE Table1 SET item1, item2, item3, item4 WHERE Table1 is TOP 1 ORDERED BY column2 ASC column1="email_address"
So i want to update only the most recent entry of a customer with a specific email address. I can't get the SQL command together that will do that.
I aint that bright so specific syntax always helps.
Thanks,

Insert / Update 2 Tables
May 12, 2008Hi,

Is it possible for me to update both pages in 1 web update page?????
Thanks in advance.

Update Field In Two Tables
Jul 25, 2006This is my curren code for updaing ESN number. But this is incorrect.
<asp:SqlDataSource ID="ESNTrackingDataSource"
UpdateCommand="UPDATE [ESNTracking] SET [EsnNumber] = @EsnNumber WHERE [EsnTrackingId] = @EsnTrackingId"
OnInit="ESNTrackingDataSource_Init"
OnUpdating="ESNTrackingDataSource_Updating"
OnUpdated="ESNTrackingDataSource_Updated"
runat="server">
<UpdateParameters>
<asp:Parameter Type="String" Name="EsnNumber"></asp:Parameter>
</UpdateParameters>
</asp:SqlDataSource>
this is the Select statment I am trying to use so that I can update the Asset in Assets table and the ESN number in the ESN table. But using ESNId and AssetId.
This is my query that returns the ones are not assigned to and
Asset
SELECT DISTINCT EsnId, EsnNumber
FROM dbo.ESNTracking
WHERE (EsnId NOT IN (SELECT EsnId FROM dbo.EsnAsset))
