I'm not a T-SQL expert so I'm calling on the pros. I want to design a stored procedure that updates only fields in a given record for which a non-null parameter is specified.
Example:
Create dbo.MySproc
@CustomerID int,
@CustomerFirstName varchar(50)=NULL,
@CustomerLastName(50)=NULL
AS
UPDATE Customers
SET
CustomerFirstName= @CustomerFirstName , //update only if non-null
CustomerLastName= @CustomerLastName //update only if non-null
WHERE CustomerID = @CustomerID
RETURN
So say when calling sproc if @CustomerFirstName is specified but @CustomerLastName is not, the field CustomerFirstName would be updated but field CustomerLastName would retain original data.
I have a 3rd party developed app which has over 42000 data fields in 1200 tables. It is a heavy transaction type app. Of these fields over 10,000 are null for every record. SOme of their homegrown references these fields (and this can be removed), and in many instances many of the fields are not referenced at all. My opinion is that these extra fields are adding a heavy overhead to updates, inserts etc to the server. Any disagreements?
I have the following store procedure which execute perfectly fine Under SSMS as it is :
-- Insert statements for procedure here SELECT APHIST.ReturnDate AS ATDATE ,API_HIST.[ActionPlanItemID] ,API_HIST.[ActionPlanID] ,PIT.[ProductItemID] ,PIT.ProductItemCode
[Code] ....
But then when I try to create a dataset using ReportBuilder and pointing to that StoreProcedure, I get the following error message box :
"Could not update a list of fields for the query. Verify that you can connect to the data source and that your query syntax is correct. An item with same key already been added" ...
I have a table used by multiple applications. One column is an Identify field and is also used as a Primary key. What isare the best practices to use get the identity value returned after an INSERT made by my code.. I'm worried that if someone does an INSERT into the same table a "zillionth" of a second later than I did, that I could get their Identity value.
the basic pattern is... a user has approvers, and those approvers have approvers as well... i have 4 columns of approvers.. and if my first approver is the manager, then my second approver will be the managers approver and my third approver will be the managers approver's approver and so on..
on my actual page, i have select fields for the app, app2, app3, app4 and i need it so that when i change the very first app, it'll automatically update app2, app3, and app4
any ideas how i would do this? im pretty new to sql but im thinking i would use some type of join?

I am having trouble getting an Update call to actually update records. The select statement is a stored procedure which is uses inner joins to link to property tables. The update, insert, and delete commands were generated by Visual Studio and only affect the primary table. So, to provide a simple example, I have a customer table with UID, Name, and LanguageID and a seperate table with LanguageID and LanguageDescription. The stored procedure can be used to populate a datagrid with all results (this works). The stored procedure also populates an edit page with one UID (this works). After the edit is completed, I attempt to update the dataset, which only has one row at this time, which shows that it has been modified. The Update modifies 0 rows and raises no exceptions. Is this because the update, insert, and delete statements do not match up one-to-one with the dataset? If so, what are my choices?
Pardon me if this question is too elementary. I am trying to create a trigger that will cause certain datafields to be updated with values from other data fields in the same row when a certain column, created specifically to fire the trigger, is updated. The purpose of this is to reduce data entry by field personnel.I think I have the create trigger statement correct, but I'm a little confused on the update statement.
In a nutshell, how can I write something like: UPDATE "TABLENAME" SET DATAFIELD1 = DATAFIELD2 WHERE RECORDNUMBER = (THE SAME RECORD NUMBER)
I do know that I have to ensure that sp_dboption Recursive Triggers value is set to false, thanks.

I have been given a request by a business analyst to update the text 'old' to 'new' within the column names / measure names and associated calculations within a PowerPivot model. There are hundred of columns / measures / calculations, etc. which need to be renamed.
Is there any way of updating these changes to the model other than making these changes manually or is there some way of doing the following type of operation in PowerPivot; -
UPDATE tblColumnNames SET Column_name, etc REPLACE ('old','new', all columns),('old','new', all measures),('old','new', all calculations) FROM tblColumnNames
Hi all,I asked a similar question a few weeks ago but I didn't explain myself to well so I was hoping for some more input.I have created a webpage in Visual web developer that contains a gridview that points to an SQL table.All works well as far as searching the table and sorting. The SQL table itself is Droped ( deleted ) and then re-created every 1 minute from a query to a linked DB2 database so that we have a "live" table of our DB2 system but in SQL.....However,There is now a requirement to be able to ADD data to this SQL table. eg: a comments field.. from the website.My procedure for re-creating the SQL DB is now useless as any data added through the website would be lost when the table gets re-created.What is the best way for me to achieve a permanent table in SQL that gets updated from the Linked server DB2 but that I can also add comments from the front end (Website Gridview)..I'm assuming some sort of update query and a join to a seperate, permanent table that contains the comments?.Please help. Ray..
I have a am doing some date calcs () . The situation is that I have a Move date (date a customer moved to a new home). I want to calculate their sales for the following 0-3 months after the move (month 0 being the move month). I have the month and year of the move (MthStart, YrStart), and I am adding 3 to MthStart to get the MthEnd of that 0-3 month period. I will then find sales BETWEEN YrStart&MthStart AND YrEnd&MthEnd (there is a YrMth field in the sales table)
Of course, for MthStarts 10, 11, and 12, the ends are 13, 14, and 15. So for these, I need to subtract 12, and increment the YrEnd by 1.
I am wondering if there is a way to update both the MthEnd and YrEnd fields at one time instead of separate SETs (or maybe I am just thinking about this the hard way to begin with). Is there a way to update both in a single CASE statement like WHEN MthEnd> 12 THEN MthEnd-12 AND YrEnd+1?
Hi All,In Oracle, I can easily make this query :UPDATE t1 SET (f1,f2)=(SELECT AVG(f3),SUM(f4)FROM t2WHERE t2.f5=t1.f6)WHERE f5='Something'I cannot seem to be able to do the same thing with MS-SQL. There areonly 2 ways I've figured out, and I fear performance cost in both cases,which are these :1)UPDATE t1 SET f1=(SELECT AVG(f3)FROM t2WHERE t2.f5=t1.f6)WHERE f5='Something'and then the same statement but with f2, and2)UPDATE t1 SET f1=(SELECT AVG(f3)FROM t2WHERE t2.f5=t1.f6),f2=(SELECT SUM(f4)FROM t2WHERE t2.f5=t1.f6)WHERE f5='Something'Is there a way with MS-SQL to do the Oracle equivalent in this case ?Thanks,Michel
I have a table with eight (8) fields, including the primary key (rfpid). Three of the fields are foreign keys, which take their values form lookup tables. They are int fields (pmid, sectorid, officeid). One of the fields in this table is based on putting together the descriptive field in the lookup table for sector (tblsector). The two other fields to be part of this string are the rfpname and rfpid. This creates the following string:
The words rfp, proposals are words that have to be part of string;
the slashes are to also appear.
current_year would be defaulting to datepart = year (2008)
The part that has the last two digits of the current year then the underscore and then the rfpid should be connected by an underscore to the rfpname. I am at a loss and would greatly appreciate any help.
I am trying to import an XLS to a table in my database. Sounds simple, but the import should be an UPDATE, not an INSERT. In other words, I want to transfer data from the XLS sheet, to specific field in my database.
Let me explain more clearly.
I have an XLS sheet with a manager ID and a employee ID. The table in the database is already populated with all employee ID's but the field manager ID is still empty. Every employee has a different manager.
The import should place the manager ID's in the fields where the employee ID is the same as in the XLS sheet.
Hi guys, I have made several Access-based CMSs but now I am using SQL Server. I can read the records but my first attempts at writing are resulting in new records (with new ID) but all the fields are null. I am posting the data from a form to the same page and an if /then statement catches the flag in the URL and runs the update script below. All the field names are correct. if request.QueryString("add")<> "" then Dim rsUpdateEntry Set rsUpdateEntry = Server.CreateObject("ADODB.Recordset") rsUpdateEntry.Open "SELECT * from generic_country_info" , oConn, 2, 3
I am attempting to update a table that drives a report. The report is at the order level. An order can have several types of demand (revenue $): Ship and/or Backordered. When I update one of these demand fields on the report table, I would expect those orders that have that type of demand to update, and those orders that don't have that type of demand to remain at their current value ($0 in this example which is the table default). But what is happening is that orders that don't have that type of demand are changing to NULL. What am i doing wrong with my update statement that is causing this?

I have a field where all of the data is 5 characters in length. The last character denotes a status and will always be an F, H, or T. I want to add a new field (which I will do manually) and populate the new field with the last character from the "old" field. Once that is complete, I want to eliminate that 5th character from the old field.

I have a project that consists of a SQL db with an Access front end as the user interface. Here is the structure of the table on which this question is based:
Code Block
create table #IncomeAndExpenseData ( recordID nvarchar(5)NOT NULL, itemID int NOT NULL, itemvalue decimal(18, 2) NULL, monthitemvalue decimal(18, 2) NULL ) The itemvalue field is where the user enters his/her numbers via Access. There is an IncomeAndExpenseCodes table as well which holds item information, including the itemID and entry unit of measure. Some itemIDs have an entry unit of measure of $/mo, while others are entered in terms of $/yr, others in %/yr.
For itemvalues of itemIDs with entry units of measure that are not $/mo a stored procedure performs calculations which converts them into numbers that has a unit of measure of $/mo and updates IncomeAndExpenseData putting these numbers in the monthitemvalue field. This stored procedure is written to only calculate values for monthitemvalue fields which are null in order to avoid recalculating every single row in the table.
If the user edits the itemvalue field there is a trigger on IncomeAndExpenseData which sets the monthitemvalue to null so the stored procedure recalculates the monthitemvalue for the changed rows. However, it appears this trigger is also setting monthitemvalue to null after the stored procedure updates the IncomeAndExpenseData table with the recalculated monthitemvalues, thus wiping out the answers.
How do I write a trigger that sets the monthitemvalue to null only when the user edits the itemvalue field, not when the stored procedure puts the recalculated monthitemvalue into the IncomeAndExpenseData table?
I have an excel file that contains column A with names of components and products followed by column B which has each respective quantity on hand. I want to import that data to our website's SQL database that has a products table with a column, Pf_ID, that has only product names not component names and In_Stock which contains out-dated information that I want updated from column B of the excel file.
I think I've figured out how to use DTS and update the two fields, but I'm afraid that when everything runs new entries will be created with component information. Is it possible to specify that only rows where Pf_ID matches some row in column A that same row's column B will be used to update the data in In_Stock. I may have just made things too confusing than they need to be, but I don't have much experience with EM or Excel.
I'm also considering trying to write a macro that will match Pf_IDs in an exported excel file of the products table and take rows out of the excel file with current quantity information putting them in a new excel file to import into the website's database.
I would like to create the trigger on tblCaseBillingDetails so that when the data in the Defendant fields are updated, the trigger fires and updates the Defendant count DefCount.
I've just written a query that successfully brings back the data from one table based on the information from another. Basically we have been given a table of information and need to update certain fields in our user_group table with the new info.
Here is the SELECT statement SELECT user_group.id, user_group.name, user_group.description, Consultants.description AS Expr10, user_group.btype, user_group.rootmenu, user_group.intra_user, user_group.primary_g_id, user_group.fname, user_group.lname, user_group.ntlogon, user_group.lang_id, user_group.[external], user_group.title, user_group.work_tel, user_group.work_fax, user_group.work_ext, user_group.mobile, user_group.sex, user_group.add2, user_group.add3, user_group.town, user_group.county, user_group.pcode, user_group.private_flag,
[code]....
We want to update the 'description' on the user_group table with the 'description' from the 'consultants' table. To test this, we only want to write the UPDATE so that it changes the description where the name is 'Adam Froth. The UPDATE statement that we've written is
UPDATE user_group SET user_group.description = Consultants.description FROM user_group INNER JOIN Consultants ON user_group.description = consultants.description WHERE name like 'Adam Froth%'
but it keeps erroring and saying that it could 'Not be bound'.

GPS,
Since you have such a dependency on dates and date calculations, you should implement a calendar table. A calendar table will make calculation such as this much more simplistic.
Calendar table link http://sqlserver2000.databases.aspfaq.com/why-should-i-consider-using-an-auxiliary-calendar-table.html.
Note the calendar table I use is a little different than this one. The only thing you will need to change is isodate to dt.
Now the code to get the results you need:

inner join Calendar cal on cal.isodate >= t1.start_date and cal.ISODate <= t1.end_date
Help - I need to import data into an existing table. Most import rows were unique, so I had no problem using DTS and appending. However, some import rows match existing rows except for one column/field that contains updated/new data, and I have to either replace the entire row with the imported row, or replace the individual field with the new data. How do I do that when there are many rows to import? It would take forever typing in all the data using UPDATE. Thanks in advance for your help!

Hi all, I am using C# for ASP.NEt 2003. I would like to know if there is any easy method to update a database with about 100 fields in it. At present, I pass all the values of the controls on the web form to the stored procedure as parameters like :- myCommand.Parameters.Add("@CustomerID", SqlDbType.Int).Value = txtCustomerID.text Like this, I add all 100 parameters. Is there any easy method to do it using a class or any other methods? Thanking you in advance, Tomy
Hi,I use view to join difference table together for some function. However,when the "real" table fields changed (e.g. add/delete/change field). Theview table still use the "old fields".Therefore everytimes when I change the real table, I also needed open theview table and save it by SQL enterprise manager manually for update theview table field.Can we use a SQL command or other method to update it directly?Regards,Silas
