database - Multiply values extracted with a select in SQL -


using sql i'd multiply values extracted using select: here example:

select number1, number2 mytable primarykey = myprimarykey

and result example is: 3, 4.

instead i'd obtain 12.

so it's possible make this?

select number1 * number2 mytable primarykey = myprimarykey

yeah got it

mysql> show create table numbers\g *************************** 1. row ***************************        table: numbers create table: create table numbers (   'id' int(11) not null,   'num1' int(11) default null,   'num2' int(11) default null,   primary key ('id') ) engine=innodb default charset=latin1 1 row in set (0.00 sec)  mysql> select * numbers; +----+------+------+ | id | num1 | num2 | +----+------+------+ |  0 |    3 |    4 | +----+------+------+ 1 row in set (0.00 sec)  mysql> select num1 * num2 numbers id = 0; +-------------+ | num1 * num2 | +-------------+ |          12 | +-------------+ 1 row in set (0.01 sec)

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac
