[英]WARNING: The option --database has been used
Running mysqlbinlog to load up binary logs from one server to another.运行 mysqlbinlog 将二进制日志从一台服务器加载到另一台服务器。
Consistently get message:始终收到消息:
WARNING: The option --database has been used.警告:选项 --database 已被使用。 It may filter parts of transactions, but will include the GTIDs in any case.
它可能会过滤部分交易,但在任何情况下都会包含 GTID。
Yah -- OK?嗯——好吗? So??
所以??
Well maybe this is a stupid question, but how am I supposed to distinguish the "GTID" of the database I want from the "GTID" of the database I don't want?好吧,也许这是一个愚蠢的问题,但是我应该如何区分我想要的数据库的“GTID”和我不想要的数据库的“GTID”? In other words, how do I specify transactions to a particular database while shutting off this annoying warning?
换句话说,如何在关闭这个烦人的警告的同时指定特定数据库的事务?
Tried adding "--include-gtids" parameter, but I think it wants a list of GTIDs.尝试添加“--include-gtids”参数,但我认为它需要一个 GTID 列表。 I don't have a list of GTIDs.
我没有 GTID 列表。 I have a database.
我有一个数据库。 Why is that complicated?
为什么这么复杂?
It's complicated because --database
doesn't mean what you probably think it means.这很复杂,因为
--database
并不意味着您可能认为它意味着什么。
It does NOT mean only include changes to the named database.这并不意味着只包括对命名数据库的更改。
This option causes mysqlbinlog to output entries from the binary log (local log only) that occur while db_name is been selected as the default database by USE.
此选项导致 mysqlbinlog 输出二进制日志(仅限本地日志)中的条目,这些条目发生在 db_name 被 USE 选择为默认数据库时。
For example:例如:
USE db1;
INSERT INTO db2.mytable ...
This will NOT be included if you use --database db2
, because db2
wasn't the default database when this transaction was written to the binary log.如果您使用
--database db2
,则不会包含此内容,因为当此事务写入二进制日志时, db2
不是默认数据库。
Another example:另一个例子:
USE db3;
UPDATE db1.mytable JOIN db2.myothertable
SET db1.col1 = ...,
db2.col2 = ...;
Should the changes to db1.mytable
resulting from this be included if you use --database db2
?如果您使用
--database db2
是否应该包括由此导致的对db1.mytable
的更改?
Trick question: the changes to neither table will be included, because the current default database was db3
.技巧问题:对这两个表的更改都不会包括在内,因为当前的默认数据库是
db3
。
