SQLite触发器查询

Question

我正在尝试执行以下查询

String CREATE_TRIGGER_DELETE_PATIENT =
                 "CREATE TRIGGER " + KEY_USERID
                   +" BEFORE DELETE ON " +  TABLE_USERS
                   +" FOR EACH ROW BEGIN "
                   +" DELETE FROM "+ TABLE_RECORDS 
                   +" WHERE " + KEY_USERID 
                   + " = " + KEY_RECORDID +" END;";

但是，“END”附近有一个错误（1）：语法错误。

我使用http://android-pro.blogspot.sg/2010/10/using-sqlite-database-with-android.html上的教程引用代码。我无法发现错误。

任何人都可以提出补救措施吗？

您可以查看此http://www.sqlite.org/lang_createtrigger.html链接，这对您有帮助。

Answer 2

尝试在;声明之前提供END。

String CREATE_TRIGGER_DELETE_PATIENT =
                 "CREATE TRIGGER " + KEY_USERID
                   +" BEFORE DELETE ON " +  TABLE_USERS
                   +" FOR EACH ROW BEGIN "
                   +" DELETE FROM "+ TABLE_RECORDS 
                   +" WHERE " + KEY_USERID 
                   + " = " + KEY_RECORDID +"; END;";

希望它有所帮助。
