如何在MySQL中使用当前数据库的名称将其删除？
为了得到当前的数据库，你可以使用SELECTDATABASE()-
select database();
以下是语法-
set @anyVariableName = database();
select @anyVariableName;
set @anyVariableName2 = concat('drop database ', @yourVariableName);
prepare anyVariableName3 from @yourVariableName2;
execute yourVariableName3;让我们执行上述查询以获取当前数据库并删除它-
mysql> set @currentDatabase = database();
mysql> select @currentDatabase;
+------------------+
| @currentDatabase |
+------------------+
| employeeonboard |
+------------------+
1 row in set (0.00 sec)
mysql> set @sqlQuery = concat('drop database ', @currentDatabase);
mysql> prepare stmt from @sqlQuery;
Statement prepared
mysql> execute stmt;为了检查是否现在的数据库中存在，使用SELECTDATABASE()-
mysql> select database();
这将产生以下输出-
+------------+ | database() | +------------+ | NULL | +------------+ 1 row in set (0.00 sec)
