How many rows can access handle?
Access tables can hold millions of records. The main constraint is the database file size. It can only hold 2Gb of data (including system information).
Which join is faster in MySQL?
A LEFT JOIN is not faster than INNER JOIN . It always depends on the structure of your table whereas the proper key index is applied to that or not. If there you do not use a Dependency Or Index Undoubtedly the Left Join is way faster because that not Scan Complete table.
How many rows is too many SQL?
Is this too much? No, 1,000,000 rows (AKA records) is not too much for a database. I ask because I noticed that some queries (for example, getting the last register of a table) are slower (seconds) in the table with 1 million registers than in one with 100. There’s a lot to account for in that statement.
Is MySQL good for large database?
MySQL was not designed for running complicated queries against massive data volumes which requires crunching through a lot of data on a huge scale. … A given MySQL query can neither scale among multiple CPU cores in a single system nor execute distributed queries across multiple nodes.
Are views faster than queries?
Views make queries faster to write, but they don’t improve the underlying query performance. … In short, if an indexed view can satisfy a query, then under certain circumstances, this can drastically reduce the amount of work that SQL Server needs to do to return the required data, and so improve query performance.

Is MySQL single threaded or multithreaded?
Yes. MySQL is fully multithreaded, and makes use of all CPUs made available to it. Not all CPUs may be available; modern operating systems should be able to utilize all underlying CPUs, but also make it possible to restrict a process to a specific CPU or sets of CPUs.
How many records can a MySQL table hold?
