问题 So Scope_Identity() returns an ?-Byte Numeric Type in SQL Server. That is not awesome. Is there a safe way to cast it to an int in a select query so we don't have to manage every whim of SQL Server in our ODBC Wrapper? 回答1: If the source column to which the identity belongs is an Integer, there's no need to cast it. The following works just fine assuming the identity column is an Integer to begin with or it fits inside an "Int". DECLARE @NewIdent Int SET @NewIdent = SCOPE_IDENTITY() 回答2:

问题 I will import many data rows from a csv file into a SQL Server database (through a web application). I need the auto generated id value back for the client. If I do this in a loop, the performance is very bad (but I can use SCOPE_IDENTITY() without any problems). A more performant solution would be a way like this: INSERT INTO [MyTable] VALUES ('1'), ('2'), ('3') SELECT SCOPE_IDENTITY() Is there any way to get all generated IDs and not only the last generated id? Thanks for your help! Best

问题 I have PK that is self incrementing key. I need to insert the record into the database and then get that PK back and use it in another insert. However I would like to do this in one transaction. Is that possible. The idea is that if something fails in any of the updates/inserts I have to do then I can rollback everything but I am under the impression that I need to do a commit. I was going to do it in ado.net at first but then switched to a stored procedure since I thought maybe that would

问题 I guess it is too late and I'm too tired to see what I'm doing wrong.

问题 I ask about alternative or similar query in informix to perform the following: INSERT INTO days (depcode,studycode,batchnum) values (1,2,3);SELECT SCOPE_IDENTITY(); I want a query to return the SCOPE_IDENTITY() during insertion statement 回答1: I know that in t-sql you have the OUTPUT statement? Where [KEY] is the column name of your primary key and @OUT_KEY is a variable you need to declare INSERT INTO days ( depcode, studycode, batchnum ) OUTPUT INSERTED.[KEY] INTO @OUT_KEY VALUES ( 1,2,3 )

问题 i'm putting values into SQL Server using a Stored Procedure. The Procedure will add an ID to the row that is added. I need to get this ID back to my code. Currently I can get the I see the output id in the OUTPUT window of Visual Studio, but can't seem to capture it in my code. Here is a summarized version of the proc: SQL : CREATE PROCEDURE dbo.DoSomething ( @var1 INT = NULL, @var2 INT = NULL, @var3 DATE = NULL ) AS BEGIN INSERT INTO atable ( vara, varb, varc ) VALUES ( @var1, @var2, @var3 )

问题 I have following table structure, for convenience purpose I am only marking individual columns Table_A ( Id, Name, Desc ) Table_1 ( Id this is identity column , Name ....) Table_2 ( Id this is identity column , Table_A_Id , Table_1_Id ) The relationship between Table_1 and Table_2 is 1...* Now I have created a table type for Table_A called TType_Table_A (which only contains Id as column and from my C# app I send multiple records). I have achieved this bulk insert functionality as desired.
