Is there any way to search data(character type or integer type) across whole database without writing any table name

Question

I want to search data across whole database, means search data just by writing DB name without mentioning any table or column name.

If it is possible then please let me know in comment section or by writing your valuable answers. I am using Mysql 5.7.12 version

I have no clue how to perform these types of queries and want answers from you all.

Thanks in advance.
