How Can I Forcefully Abort SQL Script Execution?

SQL script forcefully terminates execution: detailed explanation of the "interrupt" command

In SQL Server scripting, it is critical to control the flow of execution to handle potential errors and ensure data integrity. This article explores effective ways to stop script execution immediately, allowing developers to correct the problem before it escalates.

raiser method

For administrators with sysadmin privileges, the raiseerror method provides a way to forcefully terminate execution:

raiserror('严重错误发生', 20, -1) with log

This command forcefully terminates the connection, abruptly interrupting the script. However, it requires severity level 20 or higher and the WITH LOG option to work as expected.

It should be noted that this method requires administrator rights and will disconnect the database. Additionally, if executed without sufficient permissions, the raiseerror call will fail and the script will continue execution.

noexec method

Another method that works seamlessly with the GO statement is the noexec method:

print 'hi'
go

print '致命错误，脚本将停止执行！'
set noexec on

print 'ho'
go

-- 脚本的最后一行
set noexec off

With this method, execution stops immediately after the "Fatal Error..." message, skipping the rest of the command. It does not terminate the connection, but requires a subsequent set noexec off to resume execution.

While these methods provide reliable options for controlling script execution, be sure to carefully consider their implications. Please consult Microsoft documentation and test in a development environment before implementing in a production script.
