Selecting a float in MySQL

Question

I am trying to do a SELECT match on a table based upon an identifier and a price, such as:

SELECT * FROM `table` WHERE `ident`=\'ident23\' AND `         


        

Answer 1

Don't ever use floats for money.

Answer 2

I was searching for solution but finally I did it using my previous php number_format() which came in seeing @hmasif's solution.

Use this and you'll get your float - mysql match:

$floatmatch = number_format((float)$yourfloatvariable,5);

where 5 is five strings from decimal point. e.g. 7.93643

Answer 3

Try this: SELECT * FROM table WHERE price like 101.31;

Answer 4

Today, I also came across the same situation and get resolved just by using FORMAT function of MySQL, It will return the results that exactly match your WHERE clause.

SELECT * FROM yourtable WHERE FORMAT(col,2) = FORMAT(value,2)

Explanation: FORMAT('col name', precision of floating point number)

Answer 5

Casting to a decimal worked for me:

SELECT * FROM table WHERE CAST(price AS DECIMAL) = CAST(101.31 AS DECIMAL);

However, you may want to consider just making the price column a DECIMAL in the first place. DECIMAL is generally considered to be the best type to use when dealing with monetary values.

Answer 6

Does this work?

SELECT * , ROUND( price, 2 ) rounded
FROM table
WHERE ident = 'ident23'
HAVING rounded = 101.31
