Please excuse my ignorance. I've researched this and it appears I am asking to do something that is ridiculous, so please let me know what is wrong with my design (or my brain). I'd like to update an ID number in a table. It is an identity column. In my solution I'm adding a lot of new entries into my table and deleting old ones. Call me anal, but It's driving me nuts that my ID numbers are growing so large so quickly and that I have so many unused ID's. If you were to look over my data ID's they would be something like 1,3,45,78,88,89,103,140,219. What I'm trying to do is renumber my data so that my data currently at say ID# 1067 can be moved to the unused ID#2, etc. So I either need a way to update an Identity column...or I need a way find the lowest unused number among a list of ID's. So is there anyway to achieve what I am trying to do? I see this guy had my same OCD issue (without a solution) :-(
Hi, I am having problem in bulk update of a sql server table haning identity column from a datatable( has no identity column) using sqlbulkcopy. I tried several approaches, but it does not show any error nor is the table getting updated. But the identity value seems to getting increased every time. thanks. varun
when i alter non identity column to identity column using this Query alter table testid alter column test int identity(1,1) then i got this error message Msg 156, Level 15, State 1, Line 3 Incorrect syntax near the keyword 'identity'.
I have table of three column first column is an ID column. However at creation of the table i have not set this column to auto increment. Then i have copied 50 rows in another table to this table then set the ID column values to zero.
Now I have changed the ID column to auto increment seed=1 increment=1 but the problem is i couldn't figure out how to update this ID column with zero value set to each row with this auto increment values so the ID column would have values from 1-50. Is there a away to do this?
Ok,I just need to know how to get the last record inserted by the highestIDENTITY number. Even if the computer was rebooted and it was twoweeks ago. (Does not have to do with the session).Any help is appreciated.Thanks,Trint
I am having problems updating my zip code table that contains zip, city, state, long, lat, ect..
I have the latest CSV file, I tried to use the import wizard in SQL Server 2000 Enterprise Manager. I set the ID field as <ignore> and specified the appropriate columns for the rest of the data matching from CSV to already designed and working zip code table. Also I checked the box that said "Delete Rows in Destination Table" as well as "Enable Identity Insert" was checked
I ran the wizard, and now I have empty table and it will not insert any records because the error said that the identity column can not accept NULL.
What do I do? I am not updating the identify column so Is it telling me it can't insert NULL into ID?
I have met the interview question, I provide answer like the following from my experience. I don't know it is correct or need to supplement. Thank you for help.
Question: How to identity existing data for updating in SSIS?
Answer: If you have the same key columns such as primary key or business key, you just use them to identify existing records from data source to destination.
If you use different key columns between data source and destination, you can create permanent link table which will store business key for data source and destination, and you can compare records from linking table when you update data.
I'm working with a third-party database (SQL Server 2005) and the problem here is the following:
- There are a bunch of ETL processes that needs to insert rows on a table (let's call this table T) and at the same time, an ERP (owner of T) is up and running (reading, updating and inserting on T).
- The PK of T is an Integer.
Today all ETL processes uses (select max(ID) + 1 from T) to insert new rows, so just picture the scenario. It is a mess! Everyday they get duplicate key error when 2 or more concurrent processes are trying to insert a row (with the max) at the same time.
Considering that I can't change the PK, what is the best approach to solve this problem?
To sum up:
* I need to have processes in parallel inserting on T
The requirement is to have a table say 'child_table', with an Identity column to refer another column from a table say 'Parent_table'..
i cannot implement this constraint, it throws the error when i execute the below Alter query,
ALTER TABLE child_table ADD CONSTRAINT fk_1_ct FOREIGN KEY (child_id) REFERENCES parent_table (parent_id) ON DELETE CASCADE
the error thrown is : Failed to execute alter table query: 'ALTER TABLE child_table ADD CONSTRAINT fk_1_ct FOREIGN KEY (child_id) REFERENCES parent_table (parent_id) ON DELETE CASCADE '. Message: java.sql.SQLException: Cascading foreign key 'fk_1_ct' cannot be created where the referencing column 'child_table.child_id' is an identity column.
Hi guys, If I have a temporary table called #CTE With the columns [Account] [Name] [RowID Table Level] [RowID Data Level] and I need to change the column type for the columns: [RowID Table Level] [RowID Data Level] to integer, and set the column [RowID Table Level] as Identity (index) starting from 1, incrementing 1 each time. What will be the right syntax using SQL SERVER 2000?
I am trying to solve the question in the link below: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2093921&SiteID=1
Thanks in advance, Aldo.
I have tried the code below, but getting syntax error...
ALTER TABLE #CTE ALTER COLUMN [RowID Table Level] INT IDENTITY(1,1), [RowID Data Level] INT;
I have also tried:
ALTER TABLE #CTE MODIFY [RowID Table Level] INT IDENTITY(1,1), [RowID Data Level] INT;

Hi(SQL Server 2000)I have an existing table (t) with a column that is NOT an identity column(t.ID), but it has manually inserted "row numbers". I want to make thiscolumn become an identity column. This column is a key field to othertables, so I want to keep the row numbers that are allready inserted.From the Query Analyzer, how do I do this?Thanks in advance!Regards,Gunnar VøyenliEDB-konsulent asNORWAY

How can I create an update statement that will allow me to fill in a column if the previous column already has data in it? I am trying to do and UPDATE/SET command that allows me to extract information and populate columns within a table. However, the UPDATE/SET has to make sure that it is not overwriting information that is already in the column and if there is, to populate the column next to it, and so on until all the columns are populated.
In my UPDATE/SET I am pulling data from another table to populate into the 'add_diag' columns however, I'm not sure how to write in SQL the ability to monitor all the columns, and if for example the first three are full to then populate into the fourth and so on.
Here is my UPDATE/SET statement (while involved, I think I need something in my WHERE clause in order for this to be resolved):
Code:
update ad set add_diag_1=dsm_code from #add_diags ad join Doc_Entity de on ad.patient_id=de.patient_id and ad.episode_id=de.episode_id and doc_code = 'DCDIAG' join Patient_Assignment pa on de.patient_assignment_id = pa.patient_assignment_id and convert(char(8),de.effective_date,112) = convert(char(8),pa.date_discharged,112) left outer join Doc_Diag_Axis_I_III dx1 on de.doc_session_no=dx1.doc_session_no and de.current_version_no=dx1.version_no where dx1.sequence_no=2 and de.is_locked = 'Y' and dx1.rule_out = 'N' and is_billable = 'Y' and dx1.axis_type IN ('1','2') and de.status in ('CO' , 'SA')

hi i want to update column with new value in a table is it possible to do so in stored procedure . the name of the column will be an input to stored procedure ie at the time of writing the stored procedure i dont know which column the user will be updating
Does anyone know of the SQL statement to add additional comuns to an existing table. I know i can do it through enterprise managaer, but I want to see if I can do it from query analyzer or some script to add columns without having to recreate the table. Or a way to save off the data and recreate the table then placing data back in? I hope that makes sense. I am thinking of this from the sens of doing all updates through source safe
If amc.amc2>0 then “UPDATE amc set AMC2= AMC2 + “ & val(txtamt.text) & “where am1=1” else if amc.amc2<0 then “UPDATE amc set AMC2= “ & val(txtamt.text) & “where am1=1” end if
Here I check the value of column with if condition statement. I need to check the column with out if condition statement.
What is my doubt is that how I can check value of amc2 column while updating.
eg: update amc set case when amc2>0 then AMC2= AMC2 + “ & val(txtamt.text) like this
Is it possible with “case-when -end”?
If it is possible I can solve a big problem in my project. Can you give me an example with this query?
