How To Perform An Update To A Collumn With Two Substrings
Mar 22, 2005
I want to do the following in an update:
Update [table]
Set collumnName = Substring(collumnName, 1, 2) = '11' AND Substring(collumnName, 3, 5) = '00000'
Where (conditional statement)
SQL is not letting me perform the update because of the AND statement between the two Substring's. Is there anyway around this...is there anything else I can do to acomplish what I'm trying to do.
Hi all, I hope you guys can help me with the following bit of T-SQL. I already have a solution but I really don't like it and I've been trying to find a simpler more elegant way of doing the same thing.
Firstly, let me present you with a brief explanation of what I am trying to do together with some sample data for you to play with and hopefully assist me in finding a better solution than the one I’ve come up with.
insert into #VehMake select 222, 'FORD' union all select 210, 'FORD (USA)' union all select 223, 'FORD (AUS)' union all select 269, 'HONDA' union all select 253, 'NISSAN' union all select 280, 'VOLKSWAGEN'
This contains various vehicle makes which I'm sure you'll recognise!
insert into #VehicleHistory (PersonId, VehMakeVehModel) select 1, 'FORD (USA) MUSTANG' union all select 2, 'HONDA CIVIC' union all select 3, 'NISAAN ALMERA' union all select 4, 'VOLKSWAGEN PASSAT'
As you can see, in the second table, the second column contains a string of the vehicle Make and Model in one string. What I need to do is to split the Make and Model in to separate columns with an update statement.
This seems easy enough with a simple LIKE comparison:
VehMakeVehModel like VehMake+' %'
....BUT if you notice, there are two records in the #VehMake table that are similar but not the same. These are the 'FORD (USA)' and 'FORD (AUS)'. The update statement would return two records from the #VehMake table when trying to match with the first record in my #VehicleHistory table.
As I said, I did come up with a solution but it seems over complicated and I have a feeling that there is a way of doing this with an update. Maybe use the LEN() function but I'm not sure.
Your help would be much appreciated.
BTW, once I've identified the correct Make, I can easily populate my model as all I have to do is use the replace function on VehMakeVehModel column and remove the matched make to get the full model name.
Hope that makes sense and thanks for any help in advance.
I have a situation where my Visual C# application presents a number of fields. In order to update a student object, I wish to call a stored proc. 1 or more fields can be updated... And If one is left null, then I don't want to update it, but instead I want to keep the old value.
I am really wondering if I am approaching this the right way. The following stored proc does what I want it to do, however I'm thinking there may be a faster way...
Here it is:
-- Update a student, by ID.
DROP PROCEDURE p_UpdateStudent
CREATE PROCEDURE p_UpdateStudent
@ID INT,
@NewFName VARCHAR(25),
@NewOName VARCHAR(25),
@NewLName VARCHAR(25),
@NewDOB DATETIME,
@NewENumber VARCHAR(10),
@NewContactAID INT,
@NewContactBID INT
AS
BEGIN
SET NOCOUNT ON;
-- DECLARE THE OLD VALUES
DECLARE @FName AS VARCHAR(25)
DECLARE @OName AS VARCHAR(25)
DECLARE @LName AS VARCHAR(25)
DECLARE @DOB AS DATETIME
DECLARE @ENumber AS VARCHAR(10)
DECLARE @ContactAID AS INT
DECLARE @ContactBID AS INT
-- Get all of the old values
SELECT @FName = FName FROM TBL_Student WHERE ID = 10000
SELECT @OName = OName FROM TBL_Student WHERE ID = 10000
SELECT @LName = LName FROM TBL_Student WHERE ID = 10000
SELECT @DOB = DOB FROM TBL_Student WHERE ID = 10000
SELECT @ENumber = ENumber FROM TBL_Student WHERE ID = 10000
SELECT @ContactAID = ContactAID FROM TBL_Student WHERE ID = 10000
SELECT @ContactBID = ContactBID FROM TBL_Student WHERE ID = 10000
-- USE ISNULL to set all of the new parameters to the provided values only if they are not null
-- Keep the old ones otherwise.
SET @NewFName = ISNULL(@NewFName, @FName)
SET @NewOName = ISNULL(@NewOName, @OName)
SET @NewLName = ISNULL(@NewLName, @LName)
SET @NewDOB = ISNULL(@NewDOB, @DOB)
SET @NewENumber = ISNULL(@NewENumber, @ENumber)
SET @NewContactAID = ISNULL(@NewContactAID, @ContactAID)
SET @NewContactBID = ISNULL(@NewContactBID, @ContactBID)
-- Do the update
UPDATE TBL_Student
SET FName = @NewFName,
OName = @NewOName,
LName = @NewLName,
DOB = @NewDOB,
ENumber = @NewENumber,
ContactAID = @NewContactAID,
ContactBID = @NewContactBID
WHERE
ID = @ID
END
GO
So yeah it works. But As you can see I wish to keep an old copy of the values to perform checks pre update....
Is there any faster way, or am I on the right track? I need a pro's advice :) (before i write all of my procs!!)
I open query analyser and on one tab I update a record in a transaction and hold it.
begin tran update customers set territory = 'x' where customer = 'A00001' --rollback tran
In a second tab I attempt to update all records in the table
update customers set carrier = ''
Clear this fails because of the lock placed during the first script and this is fine.
However, is there a way to get the 2nd script to ignore the locked rows and just update as many as it can? The obvious answer seemed to be the READPAST hint like follows…
update customers with (READPAST) set carrier = ''
…but this is still blocked by the original lock. I’ve tried combining it with all sorts of other table hints but all seem to get blocked.
The following does work, ignoring the lock and not returning the data
Select * from customers with (READPAST) where customer = 'A00001'
I’ve tried combining this with the update like so…
update customers set carrier = '' from customers with (READPAST) where customer = 'A00001'
..but this is blocked too.
I’m so desperate I tried moving the update into a cursor and update one row at a time. Nothing worked. I thought I might be able to do something like this
If (Select count(*) from customers with (READPAST) where customer = 'A00001') > 0 --then perform update
..but this returns a value of 1 even though the following returns no rows.
Select * from customers with (READPAST) where customer = 'A00001'
Dear All - iam facing a problem for passing a parameter to update paradox table statment in the OLE DB Command
Briefly an OLE DB Command exist between OLE DB Source and OLE DB destination , all i want it to send the data that flow from the OLE DB Source to the update paradox table statment in OLE DB Command ,
i use the parameter annotation which is "?" to refer to the parameter in the update where clause and it sucess when i use the OLE DB Command to connect to SQL Server DB but when i use it with the Paradox Table an error appear saying that there is more than one data source column with the name "?" The data source column names must be unique.
i dont know what that means is it means that "?" it consider "?" as a column or what or is there another way to send parameter to Update statment for the paradox table differ from the SQL Server Update statment which is the "? "
i hope someone help me as soon as possible because i need it in work sOOon Thanks, Maylo
I am trying to run an update statement against a vendor's database that houses HR information. If I run a regular select statement against the database with the following query, it returns without error:
SELECT "QUDDAT_DATA"."QUDDAT-INT", "NAME"."INTERNET-ADDRESS", "QUDDAT_DATA"."QUDFLD-FIELD-ID", "QUDDAT_DATA"."QUDTBL-TABLE-ID" FROM "SKYWARD"."PUB"."NAME" "NAME", "SKYWARD"."PUB"."QUDDAT-DATA" "QUDDAT_DATA" WHERE ("NAME"."NAME-ID"="QUDDAT_DATA"."QUDDAT-SRC-ID") AND "QUDDAT_DATA"."QUDTBL-TABLE-ID"=0 AND "QUDDAT_DATA"."QUDFLD-FIELD-ID"=16 AND "QUDDAT_DATA"."QUDDAT-INT"=11237When I try to convert it into an
[Code] ....
I am assuming I am receiving this error because it doesn't know where to find QUDDAT-INT? How can I fix that?
The "QUDDAT-INT" column houses the employee number. So in the case of the SELECT query above, I am testing against a specific employee number.

I am trying to replace the path section of filenames listed in a collumn of my database. The filenames are UNC paths, and all files have 8 digit filenames with the same extension (they are all tif images). The length of the paths in the filenames will change, however.
Here is what my old paths look like:
\imageimagesNYY-MMABCDEFGH.TIF
..and here is the new path (all of the images are being consolidated into one directory):
\als-imagealscom31imagesdbABCDEFGH.TIF
------------------------------------------------------------- I have tried using the following query to do this:
update image set filename=replace(filename,'\imageimages5 0-08','\als-imagealscom31imagesdb')
This returns insanely crazy results like 460239 row affected, when it should be about a thousand. -------------------------------------------- I have also tried the following:
update image set filename=right(filename,12) + '\als-imagealscom31imagesdb' where left(filename,21) = '\imageimages5 0-08'
This affects zero rows.
Please guide me down the one true path. My coworkers are clueless and I'm quickly running out of disk on the old box.
the ids are something like this mod01-01 mod02-01 mod03-01 mod01-02 mod02-02 mod03-02 mod03-03 mod03-04 mod04-01 ....
now, i am trying to group by and count all of the ids that end with '01',
i was thinking of something like select count(id) group by id where id= ???
and the second query i need to make is one that counts not one but all the ids that end with the same last 2 digits but in one single query, how can i do that? as a possible hint, is that the only thing i KNOW that the last 2 digits can only be 01,02,03,04 and 05 but still im a bit stuck in here the result should look something like this
id total 01 4 02 3 03 1 04 1
or what suggestions can you give me for this query? even if you just help me with the first query, that would be great, thanks!! thanks!!!
I have a varchar that contains a comma-delimited list of integers, such as "12,34,56,78,123,1,123455".
I need a way to count the number of numbers in the string (or, perhaps, better stated as "I need a count of substrings") ;)
I'm thinking there must be a number of ways to calculate the number of numbers in my list of numbers, but I can only seem to come up with looping through the string/varchar and counting the number of commas, and then adding one to that final count.
Anybody know of a "cooler" way to do this? Everything I can think of involves stepping through a character at a time...
where # is the seperator between different data in the filename, in .NET i achieved to save the different data in the filename to seperate variables like this
Dim siebelId, accountNumber, docType As String
Dim counter As Integer = 0
Dim sites As String() = Nothing
sites = extension2.Split("#")
Dim s As String
For Each s In sites
If counter = 0 Then
siebelId = s
End If
If counter = 1 Then
accountNumber = s
End If
If counter = 2 Then
docType = s
End If
counter = counter + 1
Next s
How can i achieve this in SSIS where i can save these to variables for later use in an Execute SQL Task ?
Table A(Value), which contains some strings in the column "Value"
Table B(Key,Text), which also contains strings (in the column "Text")
Now I want to find all rows in B which contain at least one string of A and create a result table X with all found rows in B. B should contain the found keys and all found substrings for this key (separated with a comma)
The solution I am looking for may not use a Cursor and may not use the CONTAIN-Statement (fulltextsearch feature)..
Sorry to ask a stupid question. I have SQL Server 2000 on SBS 2003. I can't find Perform.exe. Anybody know where it should be (I'm sure that you all do!),

My e-commerce site is currently running the following process when items are shipped from the manufacturer:1. Manufacturer sends a 2-column CSV to the retailer containing an Order Number and its Shipping Tracking Number.2. Through the web admin panel I've built, a retail staff member uploads the CSV to the server.3. In code, the CSV is parsed. The tracking number is saved to the database attached to the Order Number.4. After a tracking # is saved, each item in that order has its status updated to Shipped.5. The customer is sent an email using ASPEmail from Persits which contains their tracking #.The process seems to work without a problem so long as the CSV contains roughly 50 tracking #'s or so. The retailer has gotten insanely busy and wants to upload 3 or 4 thousand tracking #'s in a single CSV, but the process times out, even with large server timeout values being set in code. Is there a way to streamline the process to make this work more efficiently? I can provide the code if that helps.
Hi all, Lets say that i have 3 tables, they are already related together, information on each of the 3 tables and their relationship between eachother can be found below:I am using Microsoft SQL Server 2005 Database in Visual Web Developer 2008 using VB programming (ADO.NET)The 3 tables are as follows:
FloorRoomLocation
Fields inside each of the tables can be found below:
The Relationships between the 3 tables are as follows:
ID field in Floor table is referenced by the field named FloorID in the Room Table ID field in Floor table is referenced by the field named FloorID in the Location table
NOTE: Location Table serves only as an extension to Floor table thus they have a 1 to 1 relationship, due to My Projects Lead's instructions I am not allowed to consolidate the Floor Table and the Location Table as 1 whole table. Floor Table has a 1 to Many Relationship with the Room Table.
I Have already done the physical relationships between each of the 3 tables in the Database Diagram, in Visual Web Developer 2008 Express Edition under the Database Explorer
So i have created this form to accept user input:
this form is in a aspx page called AddRooms.aspx
Country Name:______________ (data sent to location table)
City Name:_________________ (data sent to location table)
Building Name:______________ (data sent to location table)
FloorID:[This is a DropDownList which is databinded to the Floor Table]
Room Name:_______________ (data sent to room table)
*Just imagine that the above is a form to accept user input
*With a hit of a submit button all data will be sent to their respective tables in the database
Now i know that i have to JOIN tables in my database in order for my application to work, but i have no experience performing JOIN, i need great guys like you to help me apply JOIN to the 3 tables mentioned above, do let me know if you have any doubts in what i am trying to do.
Do give me that code that i can either apply in the (VB environment Visual Web Developer 2008) and/or in Microsoft SQL Server 2005 environment
Just need the SQL Statment that i will need to construct to perform the JOIN i need to.
I want to build some paging functionality into my repeater (b4 you ask, datagrid not providing flexibility required for presentation).
I will have no problem with the VB logic but I will need to execute SQL that only returns results from x to y (e.g. results 21 thru 40 for page 2). I know I can do something like 'SELECT TOP 20 * FROM...', or something like it, for page 1. But, I'm not sure if it's possible to build SQL for the pages greater than 1. Any suggestions.
I had my IT dept. install sql server 2005 enterprise edition on a new windows server 2003. All other machines are running sql 2000 server on windows server 2000. I am a sa and local admin on all servers. I tried performing copy database, backup and restore and detach and attach to upgrade the sql server 2000 databases to 2005 and all fail. I followed all steps. I was imformed that IT installed sp2 for sql server 2005. It's like the servers dont talk to each other. Their all on the company's domain. I am wondering if something happen with the install but the IT dept. insist that everything went fine. It's strange that I can't perform a simple backup and restore it on the new server buy when I click on restore it doesn't let me browse to get the backup file on the 2000 server. I never had a problem in Sql 2000 with backup. Can it be the installation was corrupted somehow. It seems fine. I haven't created any new databases because I wanted to move the databases from sql 2000. Can anyone help me get a clue of what the problem is please?
Hi, Appreciated someone able to provide me some clu on how to perfom DBCC CHECKDB. Is it necessary to set the database to "Read only" before execute DBCC CHECKDB?

hey guys--i need some expert advice!we have a Dell PE 2650 with 2GHz and 2MB RAM with 2000 Server. on it wehave about 6 MSSQL DB's. a couple of the DB's are the back-end for adecent sized web app (5-10 users on average, 20 users at most). manytimes, the cpu skyrockets on our db server when using the web app.sometimes things timeout, other times not. at this time, upgrading thehardware is not an option. aside from increasing the timeout periods, iwas wondering if windows 2003 server would utilize the processor better(even just a little bit?) enough to know the difference.should i attempt the upgrade, or is 2003 no more efficient withprocessor resources?thanks a bunch!
I'm working with ADO 2.8 en C++ with Visual Studio 2005. I want to perform a "select" in asynchronous mode. I don't really understand the logical of the recordset events. For example, I received a number of MoveComplete event higher than the number of rows in my recordset. It is really not clear for me ...
Does someone knows where I can find a a good example of C++ (or VB) code to manage select statements in asynchronous mode ?
Hi everyone! I am building a database in VC++2005 Express, connecting to SQL Server. I planed to add Delete function to a button, and when clicked, the data with the specific ID according to the IDTextBox->Text would be deleted from the table. However, nothing happened. I don't know what's wrong with my program.
I have two versions of the same dataflow component , i need to use the new version component in the packages created using the old version . How can i do this using the perform upgrade method .
