sql server - writing a transaction in t-sql and error handling -

-

U think there is a better way to write a transaction in T-SQL? ? Email receiver under specified subject - ==========: Description - There is a better view that maintains and that uses this transaction 

  Application performance is better =================================== ALTER PROCESS [CONTACT]. [Receiver_stpInsert] @First_Name nvarchar (30), @Last_Name nvarchar (30), @ Email Marketing (60), Get started as @Subject_Id Int session note; DECLARE @error_num int; Start transactions INSERT INTO Contact.Receiver (FIRST_NAME, LAST_NAME, email) prices (@First_Name, @Last_Name, @Email); SET @error_num = @@ error; IF (@error_num & lt;> 0) BEGIN Rollback; Return; End DECLARE @rec_record_id int; SET @rec_record_id = (contact record_id contact. Receiver where email = @ email); SET @error_num = @@ error; IF (@error_num & lt;> 0) BEGIN Rollback; Return; End INSERT INTO Contact.Receiver_Subject (Receiver_Id, Subject_Id) values ​​(@rec_record_id, @Subject_Id); SET @error_num = @@ error; IF (@error_num & lt;> 0) BEGIN Rollback; Return; END SET @error_num = @@ error; IF (@error_num & lt;> 0) BEGIN Rollback; Return; Start at the end; If you are using SQL 2005 or later, you can use the block. , Like this:    BEGIN Transactions in the beginning; INSERT INTO Contact.Receiver (FIRST_NAME, LAST_NAME, email) prices (@First_Name, @Last_Name, @Email); ... other inserts etc ... transfer contract; Finally catch if @@ transcount & gt; 0 rollback transactions; End catches;

In this way, you keep repeating blocks similar to code @@ error If you want to know how the error is, you can get different bits of information in the BEGIN catch block:

  • Returns the number of errors.
  • ERROR_SEVERITY () gives seriousness.
  • Returns the error state number.
  • ERROR_PROCEDURE () returns the stored procedure name or triggers when the error occurs.
  • ERROR_LINE () returns the line number inside the routine, causing an error.
  • ERROR_MESSAGE () Returns the full text of the error message The text contains values ​​for any replacement parameters, such as length, object name, or time.

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
