Constraints With Alphanumeric
Apr 10, 2008
Hi experts,
I am executing a script to add a column to few tables and drop existing constraints, create new foreign key constraints, indexes etc. After we test this on our development database we have to deliver the script to the customer.
My concern here is, when I have to drop the constraint with the name, I am not able to do it because its been created with alphanumeric char in the constraint name. So I end up getting the constraint name for each table. And moreover,
I wont be able to deliver the same script to the customer as the alphanumeric in the constraint names on the customer's database will be different.
Any suggestions to overcome these alphanumeric in the constraint names?
Thanks much

I know this is probably a flick of a switch but I cannot figure out which switch. Setup is SQL Server / Stored Procedures / DAL / BLL(skipped for testing) / PL. The stored procedure queries from only one table and two columns are ignored because they are being phased out. I can run the stored procedure and preview the data in the DAL but when I create a page with an ODS linked to the DAL and a GridView I get this error. I checked every column that does not allow nulls and they all have values. I checked unique columns (ID is the only unique and is Identity=Yes in the table definition). I checked foreign-key columns for values that are not in the foreign table and there are none. Any ideas why do I get this?
Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.

Hi,
I am getting the above error when trying to load a report into my Web Application, I have tracked the error down to one specific field in my database. Even though this field is a NVarChar field and is of size 30 it would seem that there is an issue returning the value from the field. I can write it into the database no problems but when I try to get it out of the database it returns the above error.
e.g
MOB 401.908.804 - Fails
0401.907.324 - okay
8239 9082 (pager) - fails
Anyone got an idea on how to fix this????
Regards..
Peter.

I have set a column called "Anumber", I am
using a computed value to get the PK ID # and
a the letter "A" to it.
('A'+CONVERT([varchar](10),[requestid],(0)))
The above works fine unless I copy a record,
The copied record never displays the correct
value like "A55" it keeps "NULL" as it value.
Is their a better way to achieve a result as
described above ?
I am coming from Foxpro to SQL, Any advice would
be great.
Thanks

Greetings all,
I have upsized 2 foxpro table to SQL Express.
In table 2 called Orphan I have/had a field that
would autonumber with the letter "U" first.
Example would create a AlphaNumber Like "U00001223"
In Foxpro this is a easy function, But I have been
unable to find a similiar way to do this in SQLEXPRESS.
Foxpro would have you define the field as Unique Number with
template defintion of "U"N8
In SQL I know you can use Numeric on a field for a unique number
but cant find setting to proced number with a "U"
Is this doable is in SQL and does anybody have a
reference point or example they could share ?
Any help would be great and hope my question made sense..

All,
I'm having trouble with a query where I need to limit a resultset by comparing (using a WHERE clause) a field that is alphanumeric with one that is numeric. I've tried converting, casting, and case statements, but I either get an overflow error or a big slap on the wrist by SQL Server 2005. Does anyone have any good solutions to this? I've been racking my brain for a while now.
Thanks for the help!

Hello,
I have a SQL database with about 300 company names and corresponding phone numbers. I would like to show a list of linkbuttons titled A-Z and when pressed, rebind the sqldatasource so that my GridView will only show company names that start with that letter.
I know there are some examples on codeproject.com, but they are a bit over my head... besides, I don't mind writing a custom select statement for the OnClick of every linkbutton if that's what I have to do. Problem is I haven't a clue how to write a select statement that will return items who's first letter matches my desired letter?
Any idea?
Thanks,
-Derek

Hi there,The age old question of creating a unique alphanumeric value automatically like ABC0001, ABC0002 Is it possible to do this automatically? That is, without having to update it which will slow the db down horribly?

How to auto increment an alphanumeric Primary Key in SQL? :( Because I want to add something like this in the Primary Key, for example i'll add a new data with an alphanumeric value of ABC-0001, then I'll add another 1, and it auto increments to ABC-0002 and so on.. How can I do it? And if I'll add a new alpha character in the Primary Key field, for example DEF-0001, then I'll add another and it auto increments to 002, and so on, and it will go back to 0001 if i'll use another combination of alpha characters. for example, i'll add a new alpha character AAA, will it go back to 0001 or it will continue? T___T I hope u get my point.. I want my table to look like this if i have added the dataABC-0001ABC-0002DEF-0001DEF-0002AAA-0001then if il add a new 1, for example ABCit will auto increment to 0003 in the same field, it will look like this after addingABC-0001ABC-0002ABC-0003DEF-0001DEF-0002AAA-0001Will it be possible? :(

I have seen this problem posted several times and not seen an applicable solution yet. No offense, the suggestions may have been good for those scenarios, but not this one.
Several (at least 4) Excel Spreadsheets come from a vendor that I need to import to a table. They are uploaded via web to a directory so they can be imported by a scheduled DTS package.
Darren Green's site gave me some good info on how to get this far, btw.
But I cannot overcome the NULL-ifying of Column Headers for Numeric fields when the spreadsheet is imported.
I've tried:
DTSDestination("Yr1") = trim(DTSSource("F7"))
DTSDestination("Yr1") = CHR(34) & trim(DTSSource("F7")) & CHR(34)
DTSDestination("Yr1") = cstr("0" & trim(DTSSource("F7)))
DTSDestination("Yr1") = clng("0" & DTSSource("F7")))
Named ranges, along with any sort of spreadsheet editing is too time consuming.
And since they come from a vendor, having them come to us with the required items in place is not possible.
Even though it seems easy enough, it's a toughy.
Any help would be rewarded with respect and admiration.
Thanks, Mike

Hi all,
I have a problem with alphanumeric codes in SSIS.
I have a sql table with a varchar column which contains codes like '080101000', in my SSIS dataflow I have a lookup against this table and the column whith the code is used as output column for my lookup transformation.
In the advance editor the output column datatype is DT_WSTR, but when the code contains only numbers like the code '080101000' the first '0' is removed! It's like the code is at some point transformed to numeric and then inserted in the output column as a string. This in nonsense!!
Does anyone have an idea how to avoid this ?

I am having some difficulty getting a query to output an alpha numeric range grouping.
I have this data set:
Despatch_id Sample_ID
MIR00831 MCR0005752
MIR00831 MCR0005753
MIR00831 MCR0005754
MIR00831 MCR0005755
MIR00831 MCR0005756
MIR00831 MCR0005757
[code]....
Output:
DESPATCH_ID SAMPLE_ID_FROM SAMPLE_ID_TO
MIR00831 MCR0005752 MCR0005762
MIR00831 MCR0005803 MCR0005806
MIR00831 MCR0005808 MCR0005813
They need to be grouped by range specific to the alpha numeric part, which can vary within the same despatch. I was thinking of using a row over partition after splitting the numeric and alpha part and to check if they are consecutive and build the range. But I am thinking that this approach is an overkill and there may be a better way to achieve this in SQL 2012.
I have included the create table scripts and example data below:
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[SAMPLE_TABLE](
[DESPATCH_ID] [nvarchar](30) NOT NULL,
[SAMPLE_ID] [nvarchar](30) NOT NULL
[code]....

I need to convert a column of data from alpha numeric to integer.
I am only querying the tables i.e. i don't have access to actually change the data tables themselves.
CAST or CONVERT throws up an error. Are there any other commands i can use at the query stage?
The data I need to convert is always actually a number. i.e. even though it is recognised as alpha numeric, the figure is a number.
I just need it to be converted to an integer so i can SUM it etc.

Hi All ,
I am having a table which contain data in below form
id startvalue endvalue
1 12:00a 12:29a
2 12:30a 12:59a
3 1:00a 1:29a
4 1:00p 1:29p
5 2:00a 2:29a
Through SQL query I want to select the id column value for the row returned for the following query
select id from mytable where '1:24a' >= startvalue and '1:24a' <= endvalue
Idea is I will pass a literal value that lies between the startvalue (nvarchar column) and endvalue (nvarchar column) to fetch the id of the row returned, which should be 3 But when I run the query it returns me 2 rows for id 3 and 4.
I believe this is because I am trying to compare nvarchar columns with ">=" and "<=" operators.
Can anyone suggest how i can select the correct value or how to do this.
Thanks,
Ashish

I need to auto increment an alphanumeric field in a table.
The process is as follows:
1. First position is static letter C for contact or static letter A for account - field contact_id
2. The following 6 positions are numeric - example of the string would be C004658
3. When new contact is entered, it should look up the highest numeric value (in this case 004658) and increment it by one - resulting in C004659
