In Mathematics, a limit is defined as a value that a function approaches the output for the given input values. Learn more about limits and their applications. Limit A limit is the value that a function approaches as its input value approaches some value. Limits are denoted as follows: The above is read as "the limit of f (x) as x approaches a is equal to L." Limits are useful because they provide information about a function's behavior near a point. Consider the function f (x) = x + 3. The figure below is a graphical representation of the limit of f (x) as x approaches 3. The blue arrows indicate the directions from which we approach x = 3, and ... The MySQL LIMIT Clause The LIMIT clause is used to specify the number of records to return. The LIMIT clause is useful on large tables with thousands of records. Returning a large number of records can impact performance.
