MYSQL PHP - get float LIKE $float

Question

I want to get rows with floats like my $float.

I used this code:

$float = $_GET[\'float\'];

$requst = mysql_fetch_array(mysql_query(\"SELEC         


        

Answer 1

Your variable already has a decimal point in it.

"SELECT * FROM floats WHERE float LIKE '$float%'"

If your float is 34.567 your statement executes as find like '34.567.%' which isn't finding any results.

Edit: how about this then?

"SELECT * FROM floats WHERE abs(float-$float)<1;"

That will bring in anything within 1?

Having said that, although you can keep floats in mysql, it might be safer to keep them as decimals with a limited number of points after the decimal.
