I am relativley new to SQL and have a question about identity fields.
I am creating a script to run everynight to insert records into a support table in a database. one of the fields is a identity field that is updated everytime a record is added locally or over the web.
Some records that are added into the database locally by users do not get added into theis support table, but so those new people entered in can use the website a entry must be added to this support table.
I am working on a script to take the records that where added by users and automatically put them in every night using a basic schedueled job.
The identy number is updated everynight in a table that collects all the important identiy numbers. I would like to use this table to alter the seed value and then increment by one every time a new record is added. This is my only sticking point so far.
Hello,When I try to run the following query on two different SQL Servers,I get error on one of the server (both has same set of data). I wastrying to get rows for ProductCode='XYZ_Q1'.SELECT ProductName, ProductType, ProductDesc FROM Product WHEREDepartmentID=12 AND ProductType > 2000 AND CAST(SUBSTRING(ProductCode,CHARINDEX('_', ProductCode)+2, 1) AS int)=1Example dataProductCode|ProductName|ProductType|DepartmentID|P roductDescXYZ_T_1|Test1|1000|12|TestXYZ_T_2|Test2|1000|12|TestABC_T_1|Test3|1000|11|TestABC_T_2|Test4|1000||11|TestXYZ_Q1|Test5|1000|12|TestABC_Q1|Test6|1000|11|TestIt's trying to cast all values under 'ProductCode' column instead ofapplying to subset with condition 'DeparmentID=12 AND ProductType >2000 'I solved the problem by equating it to whole string rather thantrying to extract the integer part of it. But I wanted find-out reasonas to why this is happenning.Is there any SQL Server setting that's causing this?Thank you very muchManchaiah
I want to crete temporary table with this coammnd "CREATE TABLE Temp (ID int, name varchar(50))". I would like to know which command is used for setting primary key and identity on ID field. Thankyou in advance.
I have a result set stored in a temporary table variable. The fields need to have heirarchy when they finaly get displayed to the user. I need to replace the repeating fields per group with NULL and leave out only one set of unique records per group.
I want to do something like this- make the fields in red NULL while leaving out the ones in green.
ValB ValB2 ValB3 ValB40 ValA50 { Row. Group B ValB ValB2 ValB3 ValB41 ValA51 }
I was able to achieve this by using @@ROWCOUNT with in a while loop by performing one UPDATE at a time (SET ROWCOUNT = 1). But i have to run Count(*) each time I loop through the update query to figure out the remaining number of rows I have per group as I need to leave out one untouched. But the Count function is taking too much time and I'm having performace issues.
Any idea how I might be able to do this in my stored proc. efficiently?
I am building a database for a new project. I am not a DBA or a database designer so please bear with me on this question. My boss believes that the only time to use an identity column is when we cannot determine a unique primary key. On tables where we can determine a unique primary key identify fields are a waste of reasources. For instance, one of the tables that I need to create is a customer table. Since all of our customers have unique customer numbers my boss believes that in this case an identity column is useless. I don't have enough experience to determine if he is correct or not. Can someone please explain the pro's and con's of using identity fields to me. Thanks
can anybody help in combining all the mentioned queries into a single query so as to display all fields in a row.

Help! I have converted my Access Jet database to a SQL Server database. In Access, I had many functions that I created to use in my queries. SQL Server does not allow for functions to be created. So, I had to create procedures in SQL Server to perform what my functions did.
I am trying to use the procedures I created on calculated fields within my SQL statement in my view. It returns an error stating that the procedure is not recognized.
How can I create functions to be used in my query?
Is there any way to create a chart using data fields from more that one query?
I tried to create two different datasets, but the chart has to be bound to only one dataset. So when I drop the data field from the second dataset onto the chart I get a SQL error.
I've also tried UNION ALL. Each of these queries is correct by itself, but UNION ALL combines GLBUDAMOUNT and GLTRXAMOUNT into one field. I need them to be two different fields so that I can do GLBUDAMOUNT VS GLTRXAMOUNT in the chart.
Hi! a) PROBLEM 1: I have set up my main database like this (of course I'm showing an abbreviation): company - int (identity)name - nchar I have several companies stored in the previous table. Now I have another table with messages: company - int (related with the company of the previous table)messageID - int (identity)contents - nchar company and messageID are the main key of this table. I want to set the messageID column to change automatically. Since I declared it as identity it is working fine, but I was looking to start it on 0 on every new company: Company messageID0 00 10 21 0 <- Here the company changed, so the messageID resets1 11 21 32 0 <- Again2 1 Any suggestions? b) PROBLEM 2:I have my database stored locally on my computer. When I finished working with the database it has a lot of data for testing. I want to upload the database to my hosting provider or to my customer's. But the identity columns keep incrementing since the last value of my tests, so it's kind of annoying to see values as: 1250, 223, etc. when I expect to see 0,1, 2 and so on. Also, for receipts this is a very important issue. How can I reset the identity fields? Thank you very much for your attention and help. CT
HiI've a tabel with two columns as identity fields (one as primary key), but I read in SQL 2000 documentation that it is permitted only one column as identity, it's true?The second field has to be autoincrement so I supposed to use identity field for it...Now the true problem, supposing that I can use two identity fields...I'd like to reset the second identity when the year change... In other words, I've to manage some spedition which are identified with XXX/year, where XXX is a number.Coming from Oracle, I supposed to use a trigger on insert which reset the sequence when the year changa, but in MS??Tnx...
I am experiencing a problem with the identitynumber field in SQL vs the autonumber field in MS Access 97. When I open the Member Contact form(Access), it generates the autonumber on the form, which is then visible on the form itself. That form has several pulldown/pop-up boxes which are used to select criteria. One of the form buttons, the Add Comments button, once pushed, it brings up a Comments form. This Comments form references the autonumber that was generated on the Member Contact form in order to open itslef. The information is then entered into the Comments form and the form is then saved. All the selected information is saved to that record upon the saving of that form.
Now, my problem has to do with getting the identity number(SQL) to generate on the Member Contact form and also allowing the Comment form to open by referencing that generated identitynumber just like Access does without having to save the record first then coming back and adding a comment later.
Do anyone know if it is possible? If so, does anyone have any suggestions on how to generate a identitynumber before saving the entire record?
I have a table that I need to add an identity field to. I created a field in the table as an INT and added values to all of the existing records. When I try to change it to an IDENTITY field I continually get an error saying 'Invalid cursor state' . The help function tells me that this is caused by not having enough space in the transaction log but I don't understand this b/c the trans log is configured to expand as needed. Anyone know how I can do this?
I am trying to set up Merge Replication on a database and want to set the IdentityRange Management to Auto for all my tables which use a Identity column.
In the wizard, on Article Properties Page, I can do this by selecting a Table, and going for its properties, but this is a tedious task as I have ~300 tables to set this property on.
Is there another way or a global location where I can set the property to true and even mention the ranges and the threshold, so that I dont have to pick each table and set it individually.
I am also aware of the fact that I can Generate a Script and modify it and run that, but I was looking for some way to do this in the wizard.
Most of the tables in my database are implemented with IDENTITY columns as the primary key. When an INSERT from my application is attempted, sometimes I get an error returned stating that insert cannot be done because of duplicate key value. If I try the INSERT again, sometimes it works(??). Of course, DBCC CHECKIDENT resets the identity value if trying the INSERT again doesn't work. Then sometime a little later, the problem happens again. Is there anything I can do other than placing into my application code the execution of dbcc checkident anytime I want to do an insert to prevent the error? By the way, DBCC CHECKDB revealed no problems.
Hi, I am trying to replicate our application database (SQL server 2005) using transactional replication to another server. What I did was, took a backup of the live database and restored in backup server with same name. Then did a transactional replication. Issue is we have few tables having Identity columns defined as primary keys and 'Not for Replication' option of these tables is 'NO'. But once published, this becomes 'Yes' and also replication failed showing an error as
Explicit value must be specified for identity column in table <table name> either when IDENTITY_INSERT is set to ON or when a replication user is inserting into a NOT FOR REPLICATION identity column.
In the table article, for the parameter 'Action If name is in use', I have selected 'Drop the existing object and create a new one' (Also tried another option 'Delete Data'). How to resolve these issues.
I have a table used by multiple applications. One column is an Identify field and is also used as a Primary key. What isare the best practices to use get the identity value returned after an INSERT made by my code.. I'm worried that if someone does an INSERT into the same table a "zillionth" of a second later than I did, that I could get their Identity value.
I have a table of raw data where each column can be null. The thought was to create an identity key (1,1) and set as primary for each row. (name/ address / zip/country/joindate/spending) with surrogate key: "pkid".However other queries will not use this primary key. So for instance they may count the # of folks at a zip, select all names, addresses etc. The queries may order by join date, or select all the people that joined on a specific date.No other code would logically use the primary key (surrogate primary id key), therefore would it still have any performance benefits? at this time the table would have no clustured or nonclustured indexes or keys. I'm curious if there are millions of records.
hi, I've done Googling and forum hunting but haven't had success finding a simple answer... My table schema is such that it requires the (int) LinkedItemID field to be nullable but still those fields which are set must not be duplicates. I see constraint is out of question and also identity doesn't seem to fit since I'm not using autofill for this particular field. Is there some other way doing this on Sql Server 2005?
I'm in the process of converting over an Access database - The existing Forms, Reports, etc are staying within the Access front-end and the Tables are now linked to the SQL database. The only problem is, most of the Tables contain Autonumber fields, so although they converted over to Identity fields, existing records work fine. When I try to add a new record, it doesn't automatically enter the next available Autonumber/Identity until I select a record which already exists to force it to update itself. When I add a new record using the original Access database, as soon as you start entering information into the new record, the next available Autonumber automatically appears. Any suggestions on forcing it to automatically appear using the SQL database and an Access form????
Hi, I'm trying to build a several tables using sql ce 3.1 I refer to the manual on Create Table: ms-help://MS.SSCE.v31.EN/ssmprog3/html/143cad25-5c1d-4c96-bd8b-6a95dbfb1b00.htm
The sample: CREATE TABLE MyCustomers (CustID int IDENTITY (100,1) PRIMARY KEY, CompanyName nvarchar (50))
Error Source: SQL Server Compact Edition ADO.Net Data Provider Error Message: There was an error parsing the query. [Token line number =1, Token line offset 40, Token in error=IDENTITY]
I tested against a SQL Desktop, everything is OK. What's wrong with the sentence? Please some advise or workaround will be appreciated Thanks MSCD Fernando Zorrilla de San Martín
I have just started using SQL Server reporting services and am stuck with creating subreports.
I have a added a sub report to the main report. When I right click on the sub report, go to properties -> Parameters, and click on the dropdown for Parameter Value, I see all Sum and Count fields but not the data fields.
For example, In the dropdownlist for the Parameter value, I see Sum(Fields!TASK_ID.Value, "AppTest"), Count(Fields!TASK_NAME.Value, "CammpTest") but not Fields!TASK_NAME.Value, Fields!TASK_ID.Value which are the fields retrieved from the dataset assigned to the subreport.
When I manually change the parameter value to Fields!TASK_ID.Value, and try to preview the report, I get Error: Subreport could not be shown. I have no idea what the underlying issue is but am guessing that it's because the field - Fields!TASK_ID.Value is not in the dropdown but am trying to link the main report and sub report with this field.
Am I missing something here? Any help is appreciated.
How can I create a Table whose one field will be 'tableid INT IDENTITY(1,1)' and other fields will be the fields from the table "ashu". can this be possible in SQL Server without explicitly writing the"ashu" table's fields name.
While I have learned a lot from this thread I am still basically confused about the issues involved.
.I wanted to INSERT a record in a parent table, get the Identity back and use it in a child table. Seems simple.
To my knowledge, mine would be the only process running that would update these tables. I was told that there is no guarantee, because the OLEDB provider could write the second destination row before the first, that the proper parent-child relationship would be generated as expected. It was recommended that I create my own variable in memory to hold the Identity value and use that in my SSIS package.
1. A simple example SSIS .dts example illustrating the approach of using a variable for identity would be helpful.
2. Suppose I actually had two processes updating these tables, running at the same time. Then it seems the "variable" method will also have its problems. Is there a final solution other than locking the tables involved prior to updating them or doing something crazy like using a GUID for the primary key!
3. We have done the type of parent-child inserts I originally described from t-sql for years without any apparent problems. (Maybe we were just lucky.) Is the entire issue simply a t-sql one or does SSIS add a layer of complexity beyond t-sql that needs to be addressed?
I want to insert a new record into a table with an Identity field and return the new Identify field value back to the data stream (for later insertion as a foreign key in another table).
What is the most direct way to do this in SSIS?
TIA,
barkingdog
P.S. Or should I pass the identity value back in a variable and not make it part of the data stream?

I am using MS SQL 2012. I have a table that contains all the data that I need, but I need to summarize the data and also add up decimal fields while at it. Then I need a total of those added decimal fields. My data is like this:
I have Providers, a unique ID that Providers will have multiples of, and then decimal fields. Here are my fields:
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
