ID – Auto IncrementingNumber_of_Records – IntAccount_Number – Varchar (Format 1234)Account_Number_Instance – Varchar (Format e.g. 1234-01)Other_Field1Other_Field2…etc.
When the Account_Number was initially inserted into the table, a Stored procedure (not written be me) was used to concatenate the Account_Number and Number_of_Records. As a result the Account_Number_Instance became, e.g. 1234-01, etc.
From the ASPX form we retrieve each of the fields above, and based on the Number_of_Records an appropriate number of records were inserted for the Account_Number.
For Example:
Account_Number = 12345Number_of_Records = 4
The result inserted into the table were as follows:
ID # of Records Acct_Number New_Num Acct_Number_Instance …
1 4 12345 12345-01
2 4 12345 12345-02
3 4 12345 12345-03
4 4 12345 12345-04
Now, I would like to UPDATE this table, and based on the original Number_of_ Records (4) I want to ADD, for Account_Number (1234) add an appropriate Number_of_Instances, beginning with the next incremental number and adding what the New Number of Records input is…
ID # of Records Acct_Number New_Num Acct_Number_Instance …
1 4 12345 12345-01
2 4 12345 12345-02
3 4 12345 12345-03
4 4 12345 12345-04
5 12345 3 12345-05
6 12345 3 12345-06
7 12345 3 12345-07
I do realize that the next time I have to update this Account_Number I am also going to have to somehow ADD only one of the #_of_Records and New_Num for the Acct_Number instances to obtain the next starting number, which in the example above would be (8)…
Any and all suggestions on how to accomplish this would be greatly appreciated!
I have a database table. I need to set a particular data field to allow for Auto Incrementing. Basically I need to set up the initial integer value to start at. Then to specify the amount to increment by. What I have done so far is to right click on the field name in SQL Server 2005. Then, on the pop-up menu I select the menu option for properties. When the properties are displayed I see some fields listed in dark grey but I am not able to edit these fields. In other words, if I try to type text in this field, nothing happens. The fields I am talking about are: Identity Increment Identity Seed Is Identity Does anyone know what the problem is? What do I have to do to edit these fields.
Here is a simplified version of my problem: I am inserting data into a table using a stored procedure. The table has an identity column that increments with each insert. When I use erroneous data in the other fields the insert fails….no surprises there! But when the next insert occurs with valid data I find that my identity field has increased even with those inserts that failed, so my sequence has jumped a few numbers. How do I get the identity inserts to roll back if the rest of the data in a row doesn’t insert successfully? Marcha x
I am porting a database from Informix to SQL Server 2000. Several fields in the informix database are specified as SERIAL, which means that they auto-increment auto-magically if you insert a 0 into them. Well...I was looking for an equivalent in SQL Server 2000, and thought I had found it in the IDENTITY column concept.
With further investigation into IDENTITY columns, however, I discovered that only one column per table can be given the IDENTITY property. Why is this? Is there a way around that? If not, is there another way to achieve this feature in SQL Server 2000? If not, any suggestions on how I can do it?
My Identity value column is not autoincrementing, its seed is set to 1, and increment set to 1. yet when i click the auto generated 'Add New Record' button in the BindingNavigator control set (in a form where it is populated with databound text boxes), this Identity column is not auto incremented?
And if i try to write a value to this column, i get the error telling me this column cannot be written to. Yet if i do not write to it, then i get "This column does not allow nulls"
To load my data i am using:
Code Snippet 'clear dataset Me.DsQuote.Clear() 'fill the datagrid with data from tblQuoteID Me.TblQuoteIDTableAdapter.Fill(Me.DsQuote.tblQuoteID)
and to save data im using:
Code Snippet Me.Validate() 'end data edit Me.TblQuoteIDBindingSource.EndEdit() 'update the dataset with table data Me.TblQuoteIDTableAdapter.Update(DsQuote.tblQuoteID)
anything im doing wrong? this data is being viewed in a datagrid btw.
Hi, I have an auto incrementing int column setup which serves as my unique primary key. Just wondering what happens when the auto increment reaches the limit? Will it recycle numbers from the begining (who's rows have obviously been deleted by this stage)?
Hi All, I need to set up a kind of identity insert that gives an output in the format: 00001, 00002, 00003 etc. Is there a formatting option for this sort of output using normal identity insert features or do I need to write a function to insert these values (perhaps as text) each time a new record is created? Sorry if this is really simple but it's only my 4th day in this job! Marcha
We have upgraded our SQL 2008 server to 2012 last month. i've noted since then that many tables that have auto increment primary key bigint field increases by 1 like it should, then for some reason it jumps up by 1000 or even 10000? i have seed adn auto increment set to 1 but doesnt effect it. Is there anything that could be causing the next value to jump that much?
If i were to replicate a database with another where in both the databases have an auto incrementing field. What could be the problems that's goin to arise out of it. How to deal with such a scenario...?????
hi there, i am new to sql server database.i am doing small projects right now using asp.net and sql to create webpages (very basic webpages) My problem is:
Problem :
i have two tables .....table 1 and table 2.
Table 1 has following fields: studentid,student name,student address.
Table 2 has following fields:studentid and course . table1 student id is the primary key refrencing table 2 student id. Now i delete a record in table 1 which will in turn also get deleted in table 2 . so for eg if i have three records 1 ,2 and 3 ....then i delete 2 in table 1 ...i will have 1 and 3 in both table 1 and table 2....now i want 3 to become 2 in both table 1 and table 2...so that i dont have empty space between two student id's 1 and 3. so this is my problem....if any one can help me out with suggestions please do.
Along with the data that I am pulling back from query, I also need to provide an ImportID column with the following requirements:
YYMMDDGP0001, YYMMDDGP0002, YYMMDDGP0003, and so on. The 0001, 0002, and 0003 part could get big into the hundreds of thousands.
I have the YYMMDDGP part down with the following expression:
SELECT CONVERT(VARCHAR(6), GETDATE(), 12) + 'GP' AS [ImportID]
Now I need to get the Auto Incrementing number part of this. I have been researching this trying SELECT INTO a temp table using the Identity Function and declaring different variables all with no luck.
I need some help for designing the IDs / Primary keys for some master tables in my database. Following are master tables. Client_Master, Buyer_Master & Seller_Master; I want to set Client_Id, Buyer_Id & Seller_Id as their respective primary keys and they should have following properties
Client_Id :- a) should be auto-incrementing value, b) unique & c)should be of the format – CLXXXXXX, where “CL” {Constant start characters} & “X” {any number 0-9} Similarly:: Buyer_Id :- BYXXXXXX Seller_Id :- SLXXXXXX

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

Hi! Let's say users of my app can build some reports based on a current database schema and my custom-database adapter will generate some SQL to get the right data. User can save his report template ( basically data needed to create SQL ) in some storage. Will it be better solution to generate stored procedure for such report and save stored proc to a database and their name with raport data so next time user needs this report it will use stored proc.

I have a problem on auto-generating medicine codes. and i hope someone would help me with my script.
as you noticed i declared two variables (@id and @code). I am having a problem in generating @code... i would just like to create an autogenerated medicines_code from another field from another table (hosp_counter.counter_id)
here is how my medicines_code should look like ('MEDS34') "where 34 is from a counter_id in hosp_counter table...
but it only creates a medicines_code = 'M' (below is the result)

I have two columns in a table right now. My query is inserting data into this table from another so that non technical users can view this database value via excel. One column shows the date and the other shows a numeric value. This value grows daily and is used to determine when a reseed of the database is needed. I would like to add a third column to this table that shows the difference in growth. For example if 9/19 had a value of 1000 and 9/20 had a value of 1100, the third column would have a value of 100. My plan is to create a column in excel that calculates the number of days until the reseed is required based on average growth. It would be much easier to get this difference in growth from the database than through an excel formula.
I've read some articles on generating tag clouds but so far only one actually showed a query. And the query was on a simple database with a few tags. In our database we have records that can have literally hundreds of unique tags. So, I'm wondering how to get a realistic result set of the top tags? I can't just do a group by and select the top 30 or 50 because that won't necessarily get me through the alphabet. I'd like to at least have as many letters from the alphabet in the tags as possible like (ant, cat, dog, horse, lion, seal, zebra) but if I do the top 30 it may cut off around the letter "c". Know what I mean? So, how can I generate an accurate tag cloud query that uses all available letters from the alphabet as starting letters for the tags? Thanks.
If I wanted to run a query on any table and in the recordset that is returned have an 'id' field (or whatever) with the record id of that record, how would I do this?
I'm thinking something like
Select field1, field2, recordNumber // derived somehow - not an actual field from table
I have a table named "Persons"  which has the following columns [ Name ,Age, City]. I have a Windows app which has  3 textboxes for each column. My requirement is when I enter only name and enter the search button, I need result similar to this query.    select * from persons where name like '@tbname%' when I enter only age and enter the search button, I need result similar to this query. select * from persons where age =@tbage when I enter name and city, I need result similar to this query. select * from persons where name like '@tbname%' and city like '@tbcity%'
If I don't enter any fields and enter the serach button,  I need result similar to this query.
select * from persons for these 3 fields I might give any combination as above. But how can  I have a single query with all these combinations. I want a single query capable of doing this. I cannot have query like this, select * from persons where name like 'tbname%' and city like 'tbcity%' and age =@age
Because if I give only name,  city is considered as null nad age is considered as 0 and I get empty result. I cannot have Stored proc and I cannot do much in C# like using "selectqueryBuilder" etc. I need pure SQL query.Â
I am developing a datagrid which will display a summary "report" of sales revenue grouped by a particular field. There will also be a drill-down on this field that will display in more detail the table of data that was used for the summary.
Because the user is selecting multiple criteria under which to run the search, I have created a dynamic query that gathers all the necessary data I need for both the drill down and the summary based on the variable parameters of the user. I've optimized the query that gathers the detailed data (taken from 7 tables) to execute far under a second.
So, that said, here's my question: It seems the most efficient way to get the summary data is to run it against the datatable (which gathers the detailed data) created by the dynamic query and just pass them both into a dataset. Can this be done? Originally, I was calling 2 separate sprocs in my application - one for the detailed data and another for the summary data using a "group by" on the table that was produced by the dynamic query (using "INTO TABLE" in the SELECT statement of the dynamic query). With this method, I received an access exception by asp.net. for the table created by the dynamic query so have dropped the "INTO TABLE", not to mention it increased the performance considerably NOT using the table.
Any suggestion on the most efficient/optimal method to use the data generated from the dynamic query sproc for the summary data? I am trying desparately to avoid running the dynamic query again just for the summary data.
I am a total newbie, so would appreciate any feedback. Also, would someone please tell me the datetime stamp function to print so that I can see how many milliseconds it takes to execute stored procedures?
I hope I'm posting this in the correct forum. If not I apologize. I have a nested select query that I imported from Oracle:
Oracle Version:
Code Snippetselect avg(days) as days from ( select dm_number, max(dm_closedate) - max(comment_closed_date) as days from dm_data where dm_type = 'prime' and dm_closedate <= '31-dec-2007' and dm_closedate >= '1-dec-2007' and program = 'aads' group by dm_number)
SQL Version:
select round(abs(avg(days)), 0) as days from (select dm.dm_number, abs(datediff(DAY,max(dm.dm_closedate), max(dm.comment_closed_date))) as days from dm_data dm, ProgramXref px where px.Program_Name = 'aads' and dm.Program_Id = px.Program_Id and dm.dm_type = 'prime' and dm.dm_closedate <= '31-dec-2007' and dm.dm_closedate >= '1-dec-2007' group by dm.dm_number)
In Oracle the query runs fine. In SQL I am getting a "Line 10: Incorrect syntax near ')'." error. If I run just the nested portion of the query, there are no errors. It only happens when the first query tries to query the nested query. Can anyone help me get the syntax correct?
I've never been able to grasp the usage of JOIN when querying the database, and would like some help building the correct SQL query for my task.My database table looks like this:

I'm hoping someone can help me. I am trying to generate query results in xml. I am using FOR XML AUTO and FOR XML AUTO, elements.
The problem is that the results are returned in xml but are trunacted - the entire results set is not returned - the results cut off midway through one row...

Since upgrading from SQL Server Management Studio 2008 R2, I've noticed that it no longer autosaves queries that have not been manually saved first. If a file has been manually saved the autorecover files end up in the following directory:
%appdata%MicrosoftSQL Server Management Studio11.0AutoRecoverDatSolution1
However, I have ended up in the situation where I have unsaved queries when my computer has crashed and have not been able to recover them.
I have also found references to .sql files stored in temp files in the following directory, but the files here seem to be very haphazardly caught:
