INTERVAL() function

MySQL INTERVAL() function returns the index of the argument that is more than the first argument.

Syntax:

INTERVAL(N,N1,N2,N3,...)

It returns 0 if 1st number is less than the 2nd number and 1 if 1st number is less than the 3rd number and so on or -1 if 1st number is NULL.

All arguments are treated as an integer.

MySQL Version: 5.6

Example: MySQL INTERVAL() function

The following MySQL statement the 1st number is 85, which is less than 175. All other numbers in the argument are smaller than 85. So, it returns the index of 175. Notice that indexing is started with the 2nd number and first position is zero.

Code:

SELECT INTERVAL(85, 1, 75, 17, 30,56, 175);

Sample Output:

mysql> SELECT INTERVAL(85, 1, 75, 17, 30,56, 175);
+-------------------------------------+
| INTERVAL(85, 1, 75, 17, 30,56, 175) |
+-------------------------------------+
|                                   5 | 
+-------------------------------------+
