对此的任何帮助将不胜感激。

评论应该让你知道我想做什么，但我很确定代码背后的逻辑是可靠的。我只是不知道语法错误在哪里。

当我尝试运行查询以更改为存储过程时，我收到以下错误：

Msg 156, Level 15, State 1, Procedure sp_delete_Contact, Line 81
Incorrect syntax near the keyword 'CREATE'.
Msg 156, Level 15, State 1, Procedure sp_delete_Contact, Line 113
Incorrect syntax near the keyword 'CREATE'.
Msg 156, Level 15, State 1, Procedure sp_delete_Contact, Line 143
Incorrect syntax near the keyword 'END'.

执行多个语句After While Condition时，需要将它们放在BEGIN END块

中

Answer 2

而且，我明白了。

我查看的WHILE循环示例未提及我需要BEGIN来匹配END。

所以是的：

WHILE (boolean)
BEGIN
    -- Do Stuff
END

SQL语法错误：消息156，'CREATE'附近的语法错误'
