For a new project. I need to create random alphanumeric characters as primary key values when inserting a record.
eg: cmSbXsFE3l8
It can start from 4 digit characters and can grow to 6, 7 as required
The database will involve more than 10000 concurrent users.
I don't want to use guid or auto increment integer or sequence.
Is it possible to have an auto increment alphanumeric primary key eg A1, A2, A3
Thanks
Paul.
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?

CustomerID = 12 AND InvoiceID = 50
I create the DML trigger for UPDATE and DELETE only, how do I retrieve the values as above ?
Jon Galloway provided a sample in http://weblogs.asp.net/jgalloway/archive/2008/01.aspx but the Primary Key Field and Primary Key Value were inserted into separate columns while I need to combine the Primary Key Field and Primary Key Value into 1 single field, using his example, I want to form the primary key as:
ScoreId = 423
ScoreId = 3064
etc.
Note that his example only show a single primary key in a table whereas I need to handle multiple primary keys in a table.
I have two practice tables I have created and want to export the values of one into the source table. I want to know if I can export into a table and have the destination table automatically give a primary key value to a record? I haven't been able to figure this out even after fiddling with the "Enable identity insert" checkbox under the Column Mappings tab. I have created source tables with and without primary keys and neither works because of the fact that I need to have a value for a primary key in order to INSERT into the destination.
Do I have to copy the source records into a staging table and assign the PK values myself by hand? This can't be the answer.

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 went through some websites for generating random characters. These provide a 7 or 8 character random letters. URL...But i do need to update 2 columns of an entire table with random characters.
Trying to use LIKE / NOT LIKE to identify values that contain any alphanumeric characters outside of A-Z e.g £%$^&*_-{[@ etc etc
The field should contain only values between A-G with a numberic e.g ABCD1234567... but some rows have characters such as above, some have spaces (weeps) , and some have letters outside the A-G range ....
Hi,
I am using SQL Server 2000. In database i am having one column named Address which contains full address of the customer. While searching i want to ignore starting numeric or alphanumeric values. Kinly guide how I can ignore numeric or alphanumeric values while searching the data.
Is it possible to write a sql statement to skip aplpha numeric values? I got a field containing these values; 20, 70, 150, 140, 100, KORT, 90, 180, 160. And I'm trying to check if any value is bigger than 175 (@Limit), but I want to skip the value 'KORT'. So is it possible to check if a value is numeric or not? ISNULL( CONVERT(int, ProductVariant.Size), 0) > @Limit Regards, Sigurd

I want to search for alphanumeric values between an upper and lower bound in a sql database.For example: search for a serial number like pvf-456-3b.

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 have an employee table
Surname GivenName
ABC x.yz
A.BC X.*YZ
A*.BC xyz
The query needs to get me the surname and givenname which have more than 1 non alphanumeric characters. In this case the output will be
a.bc x.*yz
a*.BC xyz
I know how to find non alphanumeric chars in a string but not sure if I can how to find the strings with minimum 2 non alphanumeric chars?
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 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
I am trying to sort my sql resultset by an alphanumeric column of a table which is of NVARCHAR datatype. The sample data is given below:
CREATE TABLE #Activities(activityName NVARCHAR(100))
INSERT INTO #Activities VALUES('Field phase S14-04932-01')
INSERT INTO #Activities VALUES('Phase reporting')
INSERT INTO #Activities VALUES('Phase running')
INSERT INTO #Activities VALUES('RD1')
[Code] ....
The output of the query is like this:
A1
A2
A3
A4
E1 0DAA1
E10
E2 0DAA2
[Code] .....
The output what I require is this:
A1
A2
A3
A4
E1 0DAA1
E2 0DAA2
[Code] ....
Is there a way to write an SQL statement to choose random values from a particular select statement..for example:
select * from address
I was thinking, if there was a way to use an include statement for it like:
select * from address where id IN ('generates some random values')
thanks in advance

Hi,I like to have a SQL script which could update a table to set one attributeto a random value picked from a given list. The prototyping code is asbelow:select @value_list = ('John', 'David', 'Mathew', 'Paul')....update EMP set emp_name = @random_namewhere ...where random name is randomly got from the given list. Of course there willbe a cursor so that different row may have different random name but notnecessary unique. Also the attribute and the list could be any valid commonSQL data typesThanks!Ximing

Ok I have a query "SELECT ColumnNames FROM tbl1" let's say the values returned are "age,sex,race".
Now I want to be able to create an "update" statement like "UPATE tbl2 SET Col2 = age + sex + race" dynamically and execute this UPDATE statement.

View 3 Replies View RelatedHello,
I use ODBC driver to perform SQLServer commands from C/C++ application.
An "INSERT INTO <table> (<column>) VALUES (NULL)" command has a random behavior in a SQL2000 Server running on WindowsXP.
The <column> in this command has 2 definitions about the NULL value :
- the NULL is accepted in the table definition, with <column> ut_oui_non NULL".
- the NULL is rejected in the type definition, with EXEC sp_addtype ut_oui_non, 'char(1)', 'NOT NULL' and a rule to check values with '0' or '1'
1/ The column definition in any explorer show the NULL from table deffinition
2/ The "INSERT INTO" is completed in SQL Query tool, used on Windows2000 and WindowsXP computers, connected to the same SQL2000 server.
3/ The "INSERT INTO" is completed in the application, running on Windows2000 with an ODBC driver to the same SQL2000 server.
4/ The "INSERT INTO" is rejected in the application, running on WindowsXP witjh an ODBC driver to the same SQL2000 server. The error 513 means that INSERT VALUES conflicts with previous rule. So only the type definition seems to be used.
But :
5/ This is a random error, and some INSERT with the same values in this column are completed.
6/ This random error seems to be discarded by using the "Use NULLs, paddings and warnings ANSI" checkbox in the ODBC driver user source configuration.
This checkbox is only use for enforcing the ANSI syntax in SQL commands, and has no known effect on type checking.
Do you know about any conflict of column NULL value between a type definition and a table definition ?
