I am not very clear about the use of 'identity specification properties'. There does not seem to be a great use of identity increments and seeds, it seems something that saves manual work, but to a very little extent
Anyone willing to shed some light?
Hi,
How do I determine what the next "id" will be in a collumn where the Identity Specification is turned on with Identity Increment?
I have two tables, the one contains product information and the other is a photo album. When I create a new product, then I automatically create an associated photo album. It all works fine, but I have found some problems after using this setup for a while to manage products.
For example, say I have created 10 products (id's 1 to 10) , and then I decide to remove the last 5 products from the list. The next time I add a new product, it will be product number 6, but the id will be 11 (seeing that the id's will always be unique). How do I determine what the next Identity value will be seeing that the actual last id might not be the last one that was allocated?
RegardsJan
what happens when a column marked as Identity Specification reaches the limit? for example, I have some code tables using tinyints as keys, the actual number of entries will be 20 or so but there is some volatility, so eventually the 255 limit will be reached, what happens then?
the same thing applies to ints or bigints used as keys, eventually the database must run out of numbers
information will be appreciated

I am trying to build a Windows application using: Windows XP Pro ; VS Pro 2005, C# and SQL2005.
I have a database table as follows:
eg
1) myGameRecency which contains columns : GameId (identity specification column/primary key/not null), Date (not null), [1], [2], [3], [4]
Using the myGameRecencyAllBalls table ---
I wish to insert a date into a new row but have not been able to determine how to with the identity specification on the GameId column.
Can anyone please assist?
Thank you.
lpbcorp
sqlCmd.CommandText = "DECLARE @date datetime SET @date = '" + Date +
"DECLARE @lastRowGameId int " +
"DECLARE lastrow_gameidcursor CURSOR SCROLL FOR " +
"(SELECT GameId FROM " + DBGameName.ToString() + "RecencyAllBalls) " +
"OPEN lastrow_cursor " +
"FETCH LAST FROM lastrow_gameidcursor INTO @lastRowGameId " +
"' INSERT INTO " + DBGameName.ToString() + "RecencyAllBalls.Date VALUES (@date) WHERE GameId = @lastrow_gameidcursor + 1";
sqlCmd.ExecuteScalar();
Is there anyway I can change Identity specification on column to yes ? and If I do that it supposed to take data as 1,2,3,4 like that?Â
But mine is not changing it's come up all data as 0. Is there any other way to do?Â
First of all, I'm new to the forums, and I'm still getting started with VBEE and SQL.
I'm building a simple Windows Application that has a SQL Database with three tables, related to each other. In all of them I need to set one column as a simple index for the rows (1, 2, 3... etc), to work as a PK and relate to the other tables' FKs.
I've set the property Identity Specification of the column to Yes, and added some rows of data for testing. If you just keep adding rows, the PK columns work fine, but if you start deleting rows, the numbering gets fragmented, and the relations between the tables lose integrity.
I've tried the MSDN Online Help topics, but they just tell you this:
If an identity column exists for a table with frequent deletions, gaps can occur between identity values. If you want to avoid such gaps, do not use the identity property.
So, my questions are: is there another way around this problem? How to number rows automatically and re-number them when a row is deleted, and keep the table relations working? It has anything to do with constraints?
Sorry if my question was already answered, I really couldn't find anything like my problem searching the forums. Thanks in advance.
(and also, sorry for the bad english... )
subject says it all -- is it possible to automatically expand the identity specification node in table properties for the Management Studio or VS2005 diagram mode? when creating a DB, it seems ridiculous that for EVERY table I have to add an extra click to get to just one more clickable item that ought to be exposed by default.
View 7 Replies View RelatedHi,
Using Management Studio, when I import data from one identical database to another, any identity specifications get dropped from the destination database.
(From columns which have them on the source database and which had them on the destination database.)
Any way to avoid this?
If I right click on a primary key in SQL Server management studion, I can set the identity specification for a primary keyId so that it is indexible. I do this by setting the properties for "Is Identity", "Identity Increment", and "Identity Seed". This is wonderful, but I have been asked to perform this using a script instead of the SQL server GUI/Sql Server management studio. Is this possible? Does anyone know how to do this? If so, can you show me how?

Hi, I am having a bit of hassle with trying to enter details to multiple tables in SQL Server 2005.
I have four tables, an
Attendance Table (AttendanceID(PK Identity specific), MembershipNo, Date)
Resistance Table (ResistId(PK Identity specific), Weight , Reps, Sets)
Aerobics Tables(AerobicsID(PK Identity specific), MachineID, Intensity, Time)
and a linking table for all of them.... ExerciseMaster(AttendanceID,ResistanceID,AerobicsI D)
My problem is that I can insert data to each specific table by itself using seperate insert statements.....eg....
//insert an attendance record to the attendance table
string userID;
userID = Session["User"].ToString();
SqlDataSource pgpDataSource = new SqlDataSource();
pgpDataSource.ConnectionString = ConfigurationManager.ConnectionStrings["ConnectionStringLogin"].ToString();
pgpDataSource.InsertCommandType = SqlDataSourceCommandType.Text;
pgpDataSource.InsertCommand = "INSERT INTO [Attendance] ([MembershipNo], [Date]) VALUES (@MembershipNo, @Date)";
pgpDataSource.InsertParameters.Add("MembershipNo", userID);
pgpDataSource.InsertParameters.Add("Date", txtVisitDate.Text);
int RowsAffected = 0;
try
{
RowsAffected = pgpDataSource.Insert();
}
catch (Exception ex)
{
Server.Transfer("~/Problem.aspx");
}
finally
{
pgpDataSource = null;
}
//insert an aerobics record into the aerocibs table
SqlDataSource pgpDataSource = new SqlDataSource();
pgpDataSource.ConnectionString = ConfigurationManager.ConnectionStrings["ConnectionStringLogin"].ToString();
pgpDataSource.InsertCommandType = SqlDataSourceCommandType.Text;
pgpDataSource.InsertCommand = "INSERT INTO [Aerobics] ([MachineID], [Intensity], [ExerciseTime]) VALUES (@MachineID, @Intensity, @ExerciseTime)";
pgpDataSource.InsertParameters.Add("MachineID", rower.ToString());
pgpDataSource.InsertParameters.Add("Intensity", txtRowerLevel.Text);
pgpDataSource.InsertParameters.Add("ExerciseTime", txtRowerTime.Text);
int RowsAffected = 0;
try
{
RowsAffected = pgpDataSource.Insert();
}
catch (Exception ex)
{
Server.Transfer("~/Problem.aspx");
}
finally
{
pgpDataSource = null;
}
//same code as above for the resistance table
However, i am facing the problem where this does not populate the link table(ExerciseMaster) with any information as i am unable to write the relevant IDs into the table that have been auto generated by SQL Server for each of the subTables.
I have read several forums where they recommend using something called @@IDENTITY but i have no idea how or where to use this in order to fill my exercise table...
Any help would be so much appreciated.... Also, hopefully what i have said all makes sense and someone will be able to help me...oh and one more thing...this is an ASP.NET page coding in C#
Cheers

Hello,
I have a web application (ISAPI) that accesses a SQL Server 2000 (sp3) database in the same machine as the Web Server (IIS 6). Windows 2003 Standard Edition is the operating System. So, when users access the aplication through the web it runs ok until display the error message "Invalid authorization specification" or, sometimes, another message about failure to inform ODBC DSN, although I dont use ODBC.
When the error occurs, the user press F5 in the browser and the operation goes ok. It's an intermitent and curious error.
Can somebody help me?

View 14 Replies View RelatedI have a question about Computed Column Specification which you can specify as a formula for each column inside a table.
I have now columns named Age and Class.
Classes are "Kids" (ID #1) , "Junior" (ID #2) and "Senior" (ID #3)
Kids, which is for age of 6 till 12
Junior, which is for 12 till 16
Senior, 16 and above.
I have already searched for hours (I really did) on the internet for a solution, but ended with more questions because of the complicated solutions.
Now the Age is shown as a result of a formule of DOB (Date of Birth column), now I want the exact same thing, but the age must specify which Class the user is in.
Example, when I add a user with the birthdate 25/03/1988 (DD/MM/YYYY) he/she gets 24 as age.
With this formula : (datediff(year,[age],getdate()))
Now I want that the user gets "Senior" as Class (same table).
Senior is ID 3 in this case.
Now I do know how Case, When and Then works, but the validation fails. After reading some forums I understood that I should use a create function method. I am not really experienced with creating functions. Also the coding looks more different as I am used to. How to link the Computed Column to a created formula.

The above link says the pros and cons of two SQL Server 2005 editions.
Document says Compact Edition is not good for €˜When you need a multi-user database server
€™.
What is the meaning of multi-user database?
Does this means the database strictly will not support two database connections at a time?

Hi,
We are testing our product on Windows Vista with SQL Server 2005 SP2 and are encountering an "invalid authorization specification". We make the connection through a Windows service using a standard ADO connection. I have tried changing the provider in the connection string to SQLNCLI without any success. The application is written in Delphi 5 and has worked on previous versions of Windows running SQL Server 2005.
Thanks.

Dear All,
I am using the backend SQLServer with Powerbuilder, I write a stored procedure and tried to create a datawindow to use that procedure but failed, it returns error code 22005 -Invalid Character value for cast specification. I tried to change any setting in ODBC but still failed.
Is anyone can give help? Thanks in advance.

Hi All,
accessing through ODBC a frond end application which is running on MS SQL Server 2005, works just fine with a specific setup as concerned as the decimal/thousands separators ("," for thousands and "." for decimals). If i switch these settings alternatively ("." for thousands and "," for decimals), i get this error:

I tried to search forum and internet but no luck.

I'm using FTS on on two columns (VARCHAR) of my database. The data is exported from a MySQL database to SQL Server. When populating the database the default language was set to English (or maybe neutral?), although 90% of the records are in Dutch. Now, when I change the FTS language specification to Dutch problems occur when querying the database. When I enter typical Dutch noise words in my query like "van" or "van der" the query does not return any results. When I set it back to Neutral the queries do return results, although a drawback is that I can't query for example plural forms of words. Could this be because, when populating the database, the correct language was not set? If so, is there a way to get the Full Text Index working with Dutch in a correct manner?
Thanks in advance for your replies! Would be great to get this working in Dutch!

I've been trying to connect to my local SQL Server instance (SQL Server 2005) using the SQLNCLI interface from c++ without success. I consistently receive an 'Invalid authorization specification' error (SQL state 28000 and SQL error number 0) when I call IDBInitialize::Initialize to connect to the database. I was hoping someone here could shed some light on this and help me out.
The strange thing is that I get no error if I leave the user blank (L"" in vValue.bstrVal) and try to connect. Also, IDBProperties::SetProperties returns 0 when the user is blank but 40eda when the user is set. This seems to be a message from the pipeline facility but I haven't found the description of the code (0xeda).
The user in the database is configured with no password and I can successfully connect to the server and open the database using that user through Management Studio.
I've also tried using the SQLOLEDB provider with the same results.
Suspecting that I'm setting the properties wrong I include a code snippet below showing how I'm setting the properties:
for (int i = 0; i < sizeof(dbprop) / sizeof(dbprop[0]); i++)
VariantInit(&dbprop[ i ].vValue);
// Server name
dbprop[0].dwPropertyID = DBPROP_INIT_DATASOURCE;
dbprop[0].vValue.vt = VT_BSTR;
dbprop[0].vValue.bstrVal = SysAllocString(L"localhost");
dbprop[0].dwOptions = DBPROPOPTIONS_REQUIRED;
dbprop[0].colid = DB_NULLID;
// Database
dbprop[1].dwPropertyID = DBPROP_INIT_CATALOG;
dbprop[1].vValue.vt = VT_BSTR;
dbprop[1].vValue.bstrVal = SysAllocString(L"test");
dbprop[1].dwOptions = DBPROPOPTIONS_REQUIRED;
dbprop[1].colid = DB_NULLID;
// Username
dbprop[2].dwPropertyID = DBPROP_AUTH_INTEGRATED;
