Hi!
I want to put a trigger on insert (bulk insert). It´s supposed to do RTRIM and LTRIM on the incoming data to a specific column in a table. The data comes from a textfile.
What to do? Totally stuck..
Thankful for all help!

I am trying to use the RTRIM command but it does not seem to be working. If I perform
select rtrim(name) from table
it returns the row with the spaces in it anyway. ???
If Rtrim doesn't catch space at the end is there a way to catch strings that match but don't seem to get selected correctly when matching?
View 4 Replies View RelatedCould somebody please give me a syntax that I can use to trim spaces. I have used and I still have the spaces. :
UPDATE MAP SET ROAD = RTRIM (STREET)
UPDATE MAP SET ROAD = LTRIM (STREET)
We are trying to clean up spaces at road intersections. Thanks for your assistance.
I have some data that contains spaces both before and after the text string, and now I'm wondering what would be the best method to remove these blanks (sometimes there are no blanks, so I can't check with a specifik width)?
Is it possible to do something like:
set foo = ltrim(rtrim(foo))
or do I have to split it into 2 steps?
This trimming will be done in update & insert statements

How do i remove carriage returns in SQL Server ? each of the lines have a carriage return as well as in front and back of the text.

I've tried the
update test.dbo.test
set bodytext1 = ltrim(rtrim(bodytext1))
but the whitespace/carriage returns still exists in the back and front of the text ? Anyone got any ideas ?
can anyone explain me what happens when we write the above for a col.
I k now it remove spaces but can anyone explain with exmpls
thanks
Could anyone explain why this happens:
-- All outputs works but only the first should
select 'works' where '1' = '1'
select 'works' where '1' = '1 '
select 'works' where '1 ' = '1'
Seems to me like trailing blanks are automatically trimmed, why?
You all have been so much help, but I've discovered yet another problem. I'm trying to clean up my table using the following command:
UPDATE dbo.TableName
SET First_Name = LTrim(RTrim(First_Name))But it does not seem to have any effect. Thoughts? Thanks!
I have a DistributorInvoiceNumber that can end with in 'R', 'A', 'CRR' or 'CR'.I am trying to write a case statement like so:
CASE WHEN RIGHT([ih].[DistributorInvoiceNumber],1) = 'A'
THEN 'ADJ'
WHEN RIGHT([ih].[DistributorInvoiceNumber],1) = 'R'
THEN 'REV'
WHEN RIGHT([ih].[DistributorInvoiceNumber],3) = 'CRR'
THEN 'REV'
WHEN RIGHT([ih].[DistributorInvoiceNumber],2) = 'CR'
THEN 'CREDIT'
ELSE NULL END AS 'Status'
For the most part the code is working, with the exception of the fields that just end in 'R'. An example of this is 471268R, 2525125901CRR, 11100325230CR
Basically if the number ends with an A, then its an Adjustment, if it ends with JUST an R, then its a Reversal; if it ends with just a CR then it is a Credit and if it ends with CRR then it is a Reversal (Credit Reversal). How can I differentiate between the different R's since three of them end with R? Would I use a RTRIM command somehow?
I understand that for SQL Server rtrim is not needed in where clause equates because SQL Server
automatically trims the spaces. Is rtrim necessary when comparing to a host variable since rtrim is a deterministic function? It it needed in the following example
Select ....
where
TEXT = rtrim(:I--HV-001)
TEXT is a varchar column in the SQL Server database and it is getting compared to the host variable.
I am loading a dimension using a distinct query.There are duplicates coming through and the only differnce is a trailing space on one of the columns.
RTRIM is not removing the space.
how i can fix it?
Hi,I have erronous white space at the end of my 'description' field within my'product' table. I tried using the RTRIM function but it won't let mebecause it is a TEXTBLOB (text) field.Can anyone show me how to write a query that will update all my rowsautomatically?I'm using SQL Server 2000.Thanks!
View 4 Replies View RelatedWhen is RTRIM needed in a Select ... where clause. I noticed that if I have a column named TEXT varchar(17) which is varchar and in the where clause I state where
TEXT = 'This is the text'
or I state
TEXT = 'This is the text ' followed by 4 spaces
The equate still works - so when do I need RTRIM?
Do I need RTRIM for a host variable:
...where TEXT = RTRIM(:VAR_001)
if the host variable is the same length as the TEXT column field in the SQL Server 2005 database?
I'm not sure about why I'm not able to remove spaces even after trimming them. Below is the result of query I'm usning.
select distinct LTRIM(RTRIM(Promotion_Code)) Promotion_Code
--, count(Promotion_code)
from dbo.Marketing_Promotion_Tb
where Promotion_code like '%1BTPIZZA%'
Result :
Promotion_Code  Length
1BTPIZZAÂ Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 10
1BTPIZZAÂ Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 8
Hi
I sent a long string of ID from front end to my stored procedure...till now I was using varchar(8000)...but if the string crossess that limit it is breaking.
If I try to use text datatype..It doesn't support rtrim, stuff functions etc...
So could any one suggest me a best way to save a long string without any restriction of size...
My front end is C#.Net and Back End is SQL SERVER 2000
Thanks in advance
Hey,
I'm new to this whole SQL Server 2005 thing as well as database design and I've read up on various ways I can integrate business constraints into my database. I'm not sure which way applies to me, but I could use a helping hand in the right direction.
A quick explanation of the various tables I'm dealing with:
WBS - the Work Breakdown Structure, for example: A - Widget 1, AA - Widget 1 Subsystem 1, and etc.
Impacts - the Risk or Opportunity impacts for the weights of a part/assembly. (See Assemblies have Impacts below)
Allocations - the review of the product in question, say Widget 1, in terms of various weight totals, including all parts. Example - September allocation, Initial Demo allocation, etc. Mostly used for weight history and trending
Parts - There are hundreds of Parts which will eventually lead to thousands. Each part has a WBS element. [Seems redundant, but parts are managed in-house, and WBS elements are cross-company and issued by the Government]
Parts have Allocations - For weight history and trending (see Allocations). Example, Nut 17 can have a September 1st allocation, a September 5th allocation, etc.
Assemblies - Parts are assemblies by themselves and can belong to multiple assemblies. Now, there can be multiple parts on a product, say, an unmanned ground vehicle (UGV), and so those parts can belong to a higher "assembly" [For example, there can be 3 Nut 17's (lower assembly) on Widget 1 Subsystem 2 (higher assembly) and 4 more on Widget 1 Subsystem 5, etc.]. What I'm concerned about is ensuring that the weight roll-ups are accurate for all of the assemblies.
Assemblies have Impacts - There is a risk and opportunity impact setup modeled into this design to allow for a risk or opportunity to be marked on a per-assembly level. That's all this table represents.
A part is allocated a weight and then assigned to an assembly. The Assemblies table holds this hierarchical information - the lower assembly and the higher one, both of which are Parts entries in the [Parts have Allocations] table.
Therefore, to ensure proper weight roll ups in the [Parts have Allocations] table on a per part-basis, I would like to check for any inserts, updates, deletes on both the [Parts have Allocations] table as well as the [Assemblies] table and then re-calculate the weight roll up for every assembly. Now, I'm not sure if this is a huge performance hog, but I do need to keep all the information as up-to-date and as accurate as possible. As such, I'm not sure which method is even correct, although it seems an AFTER DML trigger is in order (from what I've gathered thus far). Keep in mind, this trigger needs to go through and check every WBS or Part and then go through and check all of it's associated assemblies and then ensure the weights are correct by re-summing the weights listed.
If you need the design or create script (table layout), please let me know.
Thanks.

I want to be able to create a trigger so that when a row is inserted into table A by a specific user then the ID will appear in table B. Is it possible to find out the login id of the user inserting a row?
I believe the trigger should look something like this:
create trigger test_trigger
on a
for insert
as
insert into b(ID)
select i.id
from inserted i
where
--specific USER

View 3 Replies View RelatedWhen a row gets modified and it invokes a trigger, we would like to beable to update the row that was modified inside the trigger. This is(basically) how we are doing it now:CREATE TRIGGER trTBL ON TBLFOR UPDATE, INSERT, DELETEasupdate TBLset fld = 'value'from inserted, TBLwhere inserted.id= TBL.id....This work fine but it seems like it could be optimized. Clearly we arehaving to scan the entire table again to update the row. But shouldn'tthe trigger already know which row invoked it. Do we have to scan thetable again for this row or is their some syntax that allows us toupdate the row that invoked the trigger. If not, why. It seems likethis would be a fairly common task. Thanks.

View 4 Replies View RelatedHi,
I am not sure if this is the right forum to post this question.
I run an update statement like "Update mytable set status='S' " on the SQL 2005 management Studio.
When I run "select * from mytable" for a few seconds all status = "S". After a few seconds all status turn to "H".
This is a behaviour when you have an update trigger for the table. But I don't see any triggers under this table.
What else would cause the database automatically change my update?
Could there be any other place I should look for an update trigger on this table?
Thanks,
Hi all in .net I've created an application that allows creation of triggers, i also want to allow the deletion of triggers.
The trigger name is kept in a table, and apon deleting the record i want to use the field name to delete the trigger
I have the following Trigger
the error is at
DROP TRIGGER @DeleteTrigger
I'm guessing it dosen't like the trigger name being a variable instead of a static name
how do i get around this?
thanks in advance

Hi,
I have a trigger set on TABLE1 so that any update to this column should set off trigger to write to the AUDIT log table, it works fine otherwise but not the very first time when table1 has null in the column. if i comment out
and i.req_fname <> d.req_fname from the where clause then it works fine the first time too. Seems like null value of the column is messing things up
Any thoughts?
Here is my t-sql
Insert into dbo.AUDIT (audit_req, audit_new_value, audit_field, audit_user)
select i.req_guid, i.req_fname, 'req_fname', IsNull(i.req_last_update_user,@default_user) as username from inserted i, deleted d
where i.req_guid = d.req_guid
and i.req_fname <> d.req_fname
