With SQL 7.0 the limit is 256. These figures are hard-coded into the SQL kernel and are arbitrarily chosen by the Microsoft developers - but with good reason. The more tables there are, the longer it takes to optimise a query properly.

MySQL has no limit on the number of tables. The underlying file system may have a limit on the number of files that represent tables. Individual storage engines may impose engine-specific constraints. InnoDB permits up to 4 billion tables.

How do you find the maximum number of a table?

To find the max value of a column, use the MAX() aggregate function; it takes as its argument the name of the column for which you want to find the maximum value. If you have not specified any other columns in the SELECT clause, the maximum will be calculated for all records in the table.
