Question

Database

Does the number of tables in the database affect the fetch rate?

Answer 1

Does not affect. Except for very extreme cases that are beyond reason.

Answer 2

Number of tables or still the number of rows or columns? And at what request? If your query goes through 1 table, then the number of adjacent tables does not affect if your query affects all tables (strange, but nonetheless) of course it will.
If it's all the same about the number of rows in the table or columns, then another story.
