问题 In SSIS, I am able to make an insert of rows and retrieve their SCOPE_IDENTITY using OLE DB Command Task which calls stored procedure, but this is not bulk insert, it's slow load. Is it possible to get id of inserted rows using bulk insert in SSIS? Example: When inserting Customer, first I have to insert record in Person table and then use this FK in Customer table. UPDATE: Here's a structure of Person and Customer tables that need to be populated from external source. One option is to have

问题 I am using an INSTEAD OF insert trigger on a table to set an incrementing version number on the row and also copy the row to a 2nd history/audit table. The rows are inserted to both tables without a problem. However, I am having trouble returning the new identity from the 1st table back to the user. Schema CREATE TABLE Table1 ( id INT IDENTITY(1,1) PRIMARY KEY, name VARCHAR(250) NOT NULL UNIQUE, rowVersion INT NOT NULL ) CREATE TABLE Table1History ( id INT NOT NULL, name VARCHAR(250) NOT NULL

问题 Can anyone tell me if there is an equivalent of SCOPE_IDENTITY() when using GUIDs as a primary key in SQL Server? I don't want to create the GUID first and save as a variable as we're using sequential GUIDs as our primary keys. Any idea on what the best way to retrieve the last inserted GUID primary key? 回答1: You can get the GUID back by using OUTPUT. This works when you're inserting multiple records also. CREATE TABLE dbo.GuidPk ( ColGuid uniqueidentifier NOT NULL DEFAULT NewSequentialID(),

问题 I usually use a stored procedure when inserting records to make sure I get the correct scope_identity() value. I have a requirement to get the id field of an inserted record when using SqlClient now. My understanding is that if I batch the scope_identity() command with the insert then it will still be in the same scope as the insert command? Something like below. Hard to verify though... Will I 100% get the correct id value with this..? (id field is an auto-incrementing bigint - Sql Server)

问题 I need to fetch scope_identity() value from a stored procedure after inserting data in C# code. Here I am using 3 tier architecture. Please anyone help me protected void Submit_Click(object sender, EventArgs e) { this.CreateUserGroups(strGroupName, strDescription, strGroupType); } protected void CreateUserGroups(string strGroupName, string strDescription, string strGroupType) { string strReturn = string.Empty; strReturn = objUser.SaveCreateGroups(strGroupName, strDescription, strGroupType); }

问题 I have a handful of raw SQL queries for SQL Server which use SCOPE_IDENTITY to retrieve the generated ID for a specific INSERT immediately after that INSERT occurs all in one execution… INSERT into Batch( BatchName, BatchType, Source, Area ) Values ( @strBatchName, @strType, @strSource, @intArea ); SELECT SCOPE_IDENTITY() BatchID; The question is: What’s the best way to do that for an Oracle database? Can this be done on Oracle through standard SQL or do I have to switch this to use a stored

问题 Im trying to pass the recent ID that I just insert with Scope_Identity, and its giving me some weird stuff. it says : : Specified cast is not valid and refering to the line : int IdOfRecentHistoryGame = (Int32)commandquery.ExecuteScalar(); this is the rest of the code : string username = Session["Session"].ToString(); con = new SqlConnection("Data Source=MICROSOF-58B8A5\\SQL_SERVER_R2;Initial Catalog=Daniel;Integrated Security=True"); con.Open(); string knowWhichOne = "SELECT ID FROM Users
