抛出声明前的分号

Question

为什么在throw声明之前需要分号？ https://docs.microsoft.com/en-us/sql/t-sql/language-elements/throw-transact-sql

Answer 1

它可以解决一些含糊不清的问题

比较

BEGIN TRAN THROW --Starts a transaction named "THROW"
BEGIN TRY
    SELECT 1 / 0
END TRY

BEGIN CATCH
    ROLLBACK TRAN
    THROW /*Rolls back the transaction named "THROW"*/
END CATCH 

要

BEGIN TRAN THROW --Starts a transaction named "THROW"
BEGIN TRY
    SELECT 1 / 0
END TRY

BEGIN CATCH
    ROLLBACK TRAN; /*rolls back the tran without caring about the name*/
    THROW --rethrows the error
END CATCH
