使用Spring jdbctemplate時出錯：
view sourceprint?01 org.springframework.jdbc.UncategorizedSQLException: PreparedStatementCallback; uncategorized SQLException for SQL [insert into t_data(id,content,status,type,r_id) values(?,?,?,?,?)]; SQL state [HY000]; error code [1442]; Can't update table 't_data' in stored function/trigger because it is already used by statement which invoked this stored function/trigger.; nested exception is java.sql.SQLException: Can't update table 't_data' in stored function/trigger because it is already used by statement which invoked this stored function/trigger.

04 java.sql.SQLException: Can't update table 't_data' in stored function/trigger because it is already used by statement which invoked this stored function/trigger.

12 com.mysql.jdbc.PreparedStatement.executeInternal(PreparedStatement.java:1734)
13 com.mysql.jdbc.PreparedStatement.executeUpdate(PreparedStatement.java:2019)
原因是在觸發器中引用了觸發該觸發器的宿主表：
when you insert a record mysql is doing some lock stuff. you can't insert/update/delete rows of the same table where you insert.. because then the trigger would called again and again.. ending up in a recursion
