How to get MySQL random integer range?
To get the random integer range, use the rand() function. The query to create a table −
mysql> create table RandomIntegerDemo −> ( −> Number int −> ); Query OK, 0 rows affected (0.61 sec)
Inserting records into table. The query is as follows −
mysql> insert into RandomIntegerDemo values(1),(2),(3),(4),(5),(6),(7),(8),(9),(10),(11),(12),(13),(14); Query OK, 14 rows affected (0.14 sec) Records: 14 Duplicates: 0 Warnings: 0
Now you can display all records with the help of select statement. The query is as follows −
mysql> select *from RandomIntegerDemo;
The following is the output displaying integers −
+--------+ | Number | +--------+ | 1 | | 2 | | 3 | | 4 | | 5 | | 6 | | 7 | | 8 | | 9 | | 10 | | 11 | | 12 | | 13 | | 14 | +--------+ 14 rows in set (0.00 sec)
The query to generate the random integer range is as follows −
mysql> select Number, (FLOOR( 1 + RAND( ) *14 )) AS RandomValue −> from RandomIntegerDemo −> limit 0,14;
The output displays random integer range in the same table −
+--------+-------------+ | Number | RandomValue | +--------+-------------+ | 1 | 9 | | 2 | 8 | | 3 | 13 | | 4 | 13 | | 5 | 10 | | 6 | 10 | | 7 | 7 | | 8 | 3 | | 9 | 8 | | 10 | 2 | | 11 | 14 | | 12 | 6 | | 13 | 3 | | 14 | 9 | +--------+-------------+ 14 rows in set (0.00 sec)
