在MySQL,现有数据库有变数?
原标题:In MySQL is there a variable for the current database?

我有一份由多个数据库管理、由多个数据库管理的文件,我只是改动了MySql“USE”声明。

我只想作一个选择说明,即把目前数据库的文字作为实地加以执行。

例如:


USE my_db;

SELECT 
  CURRENT_DB, -- this is where to insert the current executing db, i.e. "my_db"
  id, name, blah, blah
FROM my_table

归还缺省(现时)数据库名称,作为图弗8特征的示意图。 如果没有违约数据库,DATABASE(签名) 在例行储存中,缺省数据库是该例行公事的相关数据库,不一定与在电话中违约的数据库相同。

  mysql> SELECT DATABASE();

提纲:

select database();
