I can't figure out if this is an acceptable operation. I need to select records from the SQL Server 2008 database and then delete them, all as a single transaction from an ASP.NET code. Note that the .NET code must be able to retrieve the data that was first selected.
Something as such:
SELECT * FROM [tbl] WHERE [id] > 6;
DELETE FROM [tbl] WHERE [id] > 6
I'm trying it with the SQL Fiddle but then if I do:
SELECT * FROM [tbl]
I get the full table as if nothing was deleted.
EDIT As requested below here's the full .NET code to retrieve the records:
string strSQLStatement = "SELECT * FROM [tbl] WHERE [id] > 6;" +
"DELETE FROM [tbl] WHERE [id] > 6";
using (SqlCommand cmd = new SqlCommand(strSQLStatement, connectionString))
{
using (SqlDataReader rdr = cmd.ExecuteReader())
{
while(rdr.Read())
{
//Read values
val0 = rdr.GetInt32(0);
val3 = rdr.GetInt32(3);
//etc.
}
}
}
This will do the select and delete simultanious:
delete from [tbl] output deleted.* WHERE [id] > 6
