问题描述
我正在将记录从一个表复制到另一个表,并且有可能某些记录可能已经在我将记录复制到的第二个表中.
I am copying records from one table to another and there is a chance that some records may already be in the second table i am copying the records to.
由于我正在复制很多行,我正在寻找一种方法来忽略来自 mysql 的所有记录已经存在的消息并继续执行 mysql 文件.
Since there are lots of rows i am copying,i am looking a way to ignore all the record already exists messages from mysql and continue executing the mysql file.
有什么办法可以抑制错误消息?.
Is there a way i can suppress the error messages?.
推荐答案
INSERT
语句支持以下修饰符:
The
INSERT
statement supports the following modifiers:
[ deletia ]
- 如果您使用
IGNORE
关键字,则在执行INSERT
语句被视为警告.例如,如果没有IGNORE
,重复表中现有UNIQUE
索引或PRIMARY KEY
值的行会导致重复键错误,并且语句被中止.使用IGNORE
,该行仍然没有插入,但没有发出错误. - If you use the
IGNORE
keyword, errors that occur while executing theINSERT
statement are treated as warnings instead. For example, withoutIGNORE
, a row that duplicates an existingUNIQUE
index orPRIMARY KEY
value in the table causes a duplicate-key error and the statement is aborted. WithIGNORE
, the row still is not inserted, but no error is issued.
