我可以使用指定数据库的服务器触发器阻止插入到所有表中吗

Answer 1

如果您希望通过编写服务器触发器来防止将记录插入任何表中，那么答案就是不可能。

服务器触发器只处理DDL（CREATE，ALTER，DROP ...）而不处理DML（INSERT，UPDATE，DELETE）：

服务器触发器：

-- Trigger on a CREATE, ALTER, DROP, GRANT, DENY, REVOKE,  
--  or UPDATE STATISTICS statement (DDL Trigger)  

CREATE TRIGGER trigger_name   
ON { ALL SERVER | DATABASE }   
[ WITH <ddl_trigger_option> [ ,...n ] ]  
{ FOR | AFTER } { event_type | event_group } [ ,...n ]  
AS { sql_statement  [ ; ] [ ,...n ] | EXTERNAL NAME < method specifier >  [ ; ] }  

<ddl_trigger_option> ::=  
    [ ENCRYPTION ]  
    [ EXECUTE AS Clause ]  



-- Trigger on a LOGON event (Logon Trigger)  

CREATE TRIGGER trigger_name   
ON ALL SERVER   
[ WITH <logon_trigger_option> [ ,...n ] ]  
{ FOR| AFTER } LOGON    
AS { sql_statement  [ ; ] [ ,...n ] | EXTERNAL NAME < method specifier >  [ ; ] }  

<logon_trigger_option> ::=  
    [ ENCRYPTION ]  
    [ EXECUTE AS Clause ]
