sql-server - throw 语句前加分号

Question

为什么在 throw 语句之前需要有分号？ https://learn.microsoft.com/en-us/sql/t-sql/language-elements/throw-transact-sql

Answer 1

它可以解决一些歧义

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 

至

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
