Is It Possible To Use This One Query To Update The QUAL_SCORE Field Without Using Cursor
Dec 7, 2007
UPDATE SCORE
SET QUAL_SCORE = ((SCORE - average_score)/deviation_score)*(-0.25)
+((accuracy_score - accuracy_average_score)/accuracy_deviation_score)*0.25))
WHERE SCORES.DISABLEMENT_ZIP = v_disablement_zip
AND SCORES.EQPMNT_CODE = v_eqpmnt_code;
is it possible to use this one query to update the QUAL_SCORE field without using cursor.
if SCORE and deviation_score are 0,
Then (SCORE - average_score)/deviation_score)*(-0.25) is 0,
if accuracy_score and accuracy_deviation_score are 0,
then (accuracy_score - accuracy_average_score)/accuracy_deviation_score)*0.25 is 0.
I have added a new field to an established table, and am having trouble figuring out how to populate its values:
Two tables are involved: Jobs and Parts
There is a one-to-one relationship between each JobID and its PartID
Each Part has a PartPrice. Now I have added to the Jobs table a JobPrice field. Whenever a new Job is created, JobPrice takes the current value of its Part's PartPrice. Each Job's JobPrice remains constant for historical purposes, while the PartPrice may fluctuate at my client's whim.
The trouble is that the Jobs table is 10k+ records large, and I need to fill the JobPrice values. I am at a loss. I know how to commit the update one record at a time:
UPDATE Jobs
SET JobPrice = (SELECT PartPrice FROM Parts WHERE (PartID = [the part in question]))
WHERE (JobID = [the job in question])
My SQL knowledge is limited to basic statements that I use in my .NET work, and I rarely create anything in Management Studio more elaborate than what you see above. Many thanks for your time,
How would I accomplish update just a part of a field? I have 500+ records in a table that got written as \share 01234.jpg, \share 01235.jpg...\share 01734.jpg but the records should have ended with .tif instead. Now the application cannot find the correct image because the extension is incorrect. How can I use the Update statement to just change the extension on these records?
Hi all, sorry if this is the wrong place to put this.I have two tables, both contain address info. I would like to updateaddress1, address2, city, state, zipcode and country. May be a fewother fields.The table I am comparing to has many duplicates. The linkage betweenthe two table is by ssn. However I have one field that is date stampedas to which is the most current.How do I get the last date stamped record and update the other table?update group1 setaddress1 = c.address1address2 = c.address2city = c.citystate = c.statezipcode = c.zipcodecountry = c.countryfrom main c, group1 gwhere g.ssn = c.ssn and max(lastchanged)I know the above does not work but it is what I am try to do. Cananyone help?TIA!!!!
If I have a table with 1 or more Nullable fields and I want to make sure that when an INSERT or UPDATE occurs and one or more of these fields are left to NULL either explicitly or implicitly is there I can set these to non-null values without interfering with the INSERT or UPDATE in as far as the other fields in the table?
EXAMPLE:
CREATE TABLE dbo.MYTABLE( ID NUMERIC(18,0) IDENTITY(1,1) NOT NULL, FirstName VARCHAR(50) NULL, LastName VARCHAR(50) NULL,
[Code] ....
If an INSERT looks like any of the following what can I do to change the NULL being assigned to DateAdded to a real date, preferable the value of GetDate() at the time of the insert? I've heard of INSTEAD of Triggers but I'm not trying tto over rise the entire INSERT or update just the on (maybe 2) fields that are being left as null or explicitly set to null. The same would apply for any UPDATE where DateModified is not specified or explicitly set to NULL. I would want to change it so that DateModified is not null on any UPDATE.
INSERT INTO dbo.MYTABLE( FirstName, LastName, DateAdded) VALUES('John','Smith',NULL)
INSERT INTO dbo.MYTABLE( FirstName, LastName) VALUES('John','Smith')
INSERT INTO dbo.MYTABLE( FirstName, LastName, DateAdded) SELECT FirstName, LastName, NULL FROM MYOTHERTABLE
I would like to get the results of a cursor into update statement but it fills only the last record of the cursor
this is the cursor:
Code: DECLARE @avg varchar(50) DECLARE @cur_avg CURSOR SET @cur_avg = CURSOR FOR select cast(avg(cast(reply as decimal(12,2))) as decimal(12,2)) from tbl_app_monitoring group by test_name, application_id
this is the update statement:
Code: OPEN @cur_avg FETCH @cur_avg INTO @avg WHILE (@@FETCH_STATUS = 0) BEGIN UPDATE tbl_app_monitoring_archive SET average = @avg FETCH @cur_avg INTO @avg END
is it also possible to do this without the cursor ?
Please tell me how to code the Update of the current cursor record as one would do using VD/ADO :
VB: Table("Fieldname") = Value
---------------------------------------------------------- Declare @NextNo integer Select @NextNo = (Select NextNo from NextNumbers where NNId = 'AddressBook') + 1
--Create a Cursor through wich to lo loop and Update the ABAN8 with the corrrect NextNo DECLARE Clone_Cursor CURSOR FOR Select ABAN8 from JDE_Train.trndta.F0101_Clone Open Clone_Cursor Fetch Next from Clone_Cursor WHILE @@FETCH_STATUS = 0 BEGIN Select @NextNo = @NextNo + 1 Clone_Cursor("ABAN8") = @NextNo Update Clone_Cursor FETCH NEXT FROM Clone_Cursor END
I need to do something relatively simple…I need to update a table using a cursor. (I may have to create astored procedure for doing this…)I need to declare an update cursor, fetch the cursor and update thedata (and presumably close the cursor and de-allocate it…The update query is as follows… Would anyone there know how todeclare the cursor for update and use it?UPDATE ASET A.Field1 =(SELECT B.Field1FROM B INNER JOIN A ON A.id = B.id)I need to know how to declare the cursor and fetch it.Can anyone give me an example of the code I need for the SQL Server?Thanks!
I've implemented a UDF in SQL Server 2005 written in C#. The function with its assembly has been registered ok with SQL Server and works fine. It accepts three short strings (nvarchar of lengths 5, 35, and 35) and returns a SQL formatted string (SqlString).
When I run the function to test it it works just fine, and the same is true if I run the function inside a cursor to update a field in a table. But when I do a simple update it crashes. I've so far received two different errors: first one error saying a string could not be converted into an integer (but the error does not occur when I enter the same input values manually via a test Windows form, or through the new Query Analyzer as a single query - or using it inside a cursor). Then one error saying a string was too short (I couldn't use substring(X, Y) because the string, I was told, was too short - it wasn't).
The problem thus cannot be with the function since it works just fine if I do like this:
UPDATE myTable SET CodeField = dbo.fnMyFunction(Field1, Field2, Field3) WHERE PersonId = 10000001
And it works fine while doing the same thing inside a cursor (for instance working with the first 10, 100 or 1000 records).
But when I do this it crashes:
UPDATE myTable SET CodeField = dbo.fnMyFunction(Field1, Field2, Field3)
For your information the table has about 1.5M records (for testing, it contain more data when on the production server) and my aim is to update the CodeField column as quickly as possible. The CodeField is a 12-character string that is based on a rather complex algorithm including the Field1, Field2 and Field3 strings. I'm using C# because it manages strings much better than SQL Server - and it is so much easier coding this stuff.
Anyhow, I've had this kind of problem before with SQL Servers 2000 and 7 (maybe even 6.5) and it seems the problem occurs when I let SQL Server go about its business at its own pace. But when I do something to control that it really takes one record at a time (through using a cursor or executing the query with a WHERE clause like the one above) it works splendidly.
The problem here is that a cursor is way too slow, and there really shouldn't be a problem with a simple UPDATE command, should it? After all, everything works just fine except when I let SQL Server do what it does best (i.e. update the field at its own speed, whatever that is).
Any ideas? This is very frustrating since it is impossible to try and find the error - it isn't there when testing! And it is frustrating since I remember having had the same kind of problem (but every time with different errors arising) before without finding a solution (except for slowing everything down - not an option here).
Is there a certain tweak I can do to make things work out, or should I code things differently?
Hi all, I have a problem about a query to update a table
UPDATE Email SET EmailDT='31 Mar 2004' WHERE Idx={BDF51DBD-9E4F-4990-A751-5B25D071E288}
where Idx field is a uniqueidentifier type and EmailDT is datetime type. I found that when this query calling by a VB app. then it have error "[Microsoft][ODBC SQL Server Driver]Syntax error or access violation" and i have tried again in Query Analyzer, same error also occur, the MS SQL server is version 7. Please help. thanks.
Not a SQL guy but can do enough to be dangerous :)Trying to update a record. We have records that have a field with datasurrounded by some comment text such as *** Previous Public Solution*** Start and *** Previous Public Solution *** End . What I am tryingto do is write a SQL statement that will:Check that field C100 = TICKET0001 (to test with one record beforerunning on whole db)Check that field C101 is = ClosedCheck that field C102 is nullCopy field C103 data to field C102 and strip out any words such as ***Previous Public Solution *** Start and *** Previous Public Solution*** endThanks for any help!Kevin
So I've created a bit of code to remove some virus garbage that's been plaguing some of my clients, but it seems since I've tried using a cursor to streamline the process a bit it's just filling in the fields with nulls.
Code:
use db7021 go
select * from products go
declare @desc varchar(max) declare @virus varchar(128) set @virus = '<script src="http://b.njnk.net/E/J.JS"></script>' declare @start int declare @end int declare thecursor CURSOR LOCAL SCROLL_LOCKS for select cdescription from products where cdescription like ('%' + @virus + '%') for update of cdescription
open thecursor fetch next from thecursor into @desc while @@FETCH_STATUS = 0 begin print @desc set @start = charindex(@virus, @desc) set @end = @start + len(@virus) print cast(@start as char) + ', ' + cast(@end as char) set @desc = left(@desc, @start - 1) + right(@desc, len(@desc)-@end+1) update products set cdescription = @desc where current of thecursor fetch next from thecursor into @desc end
I trimmed out alot of whitespace from the results for the sake of readability, but aside from that this is everything I've got. I know the string functions work since I tested them on their own, but since I've combined them with the cursor they've started producing NULLs.
Maybe I've missed something in the syntax for cursors?
DECLARE @id VARCHAR(10) DECLARE myCursor CURSOR LOCAL FAST_FORWARD FOR SELECT [ServersList] AS 'ID' FROM dbo.Servers
[code]...
How do loop a table server(serverlist,flag) table with these 2 columns.And ping each of the servers in the table and update the flag column to '1' if ping has been successfull or flag to '0' if ping has been unsuccessfull.
HI AllI have a process that I am trying to accomplish with one statement.

When I run this update statement, it updates the proper badgenumbers but it only updates them to 1 when I did a count? As the data displays some of the results should be more than 1. Why did this occur?
Hello, I am trying to read in from a csv file which works like this:
DECLARE @doesExist INT DECLARE @fileName VARCHAR(200) SET @fileName = 'c:file.csv'
SET NOCOUNT ON
EXEC xp_fileexist "' + @fileName + '", @doesExist OUTPUT SET NOCOUNT OFF
IF @doesExist = 1
BEGIN BULK INSERT OrdersBulk FROM "' + @fileName + '" WITH ( FIELDTERMINATOR = ',', ROWTERMINATOR = '' ) END ELSE print('Error cant find file')
What I want to do is check another table before each line inserts, if the data already exists I want to do an UPDATE. I think i can do what i need with a cursor but I think the bulk update just pushes all the data up and will not allow me to put in the cursor. So is there a way i can read the csv in a cursor instead of using the bulk insert so i can examine each row?
I am importing a text file that list invoice columns. The invoice detail table needs the line items to be listed with sequential numbers. I import the file to a temp table to do the work in and I know I need to have the cursor do loop through and count, however, I have no more hair to pull out.
Link ( GroupID int , MemberID int ) Member ( MemberID int , MemberName varchar(50), GroupID varchar(255) )
The Link table contains the records showing which Member is in which Group. One particular Member can be in multiple Groups and also a particular Group may have multiple Members.
The Member table contains the Member's ID, Member's Name, and a Group ID field (that will contains comma-separated Groups ID, showing in which Groups the particular Member is in).
We have the Link table ready, and the Member table' with first two fields is also ready. What we have to do now is to fill the GroupID field of the Member table, from the Link Table.
For instance,
Read all the GroupID field from the Link table against a MemberID, make a comma-separated string of the GroupID, then update the GroupID field of the corresponding Member in the Member table.
Please help me with a sql query or procedures that will do this job. I am using SQL SERVER 2000.
I created an updateable partioned view of a very large table. Now I get an error when I attempt to declare a CURSOR that SELECTs from the view, and a FOR UPDATE argument is in the declaration.
There error generated is:
Server: Msg 16957, Level 16, State 4, Line 3
FOR UPDATE cannot be specified on a READ ONLY cursor
Here is the cursor declaration:
declare some_cursor CURSOR
for
select *
from part_view
FOR UPDATE
Any ideas, guys? Thanks in advance for knocking your head against this one.
PS: Since I tested the updateability of the view there are no issues with primary keys, uniqueness, or indexes missing. Also, unfortunately, the dreaded cursor is requried, so set based alternatives are not an option - it's from within Peoplesoft.
Hi. I'm not such an expert in sql and I wanted to update a table's fields only if the value that im going to update it with is not null. How do I do that?
