I have price column in MySQL contains this values :
price |
---|
1020.2200 |
202.0000 |
0.5000 |
820.6700 |
I want to split at the floating point.
Here is what I'm trying to get :
price | p_units | p_decimals |
---|---|---|
1020.2200 | 1020 | 22 |
202.0000 | 202 | 00 |
0.5058 | 0 | 50 |
820.6700 | 820 | 67 |
This is the SQL statement I've written so far :
SELECT
price, FLOOR(price) AS `p_units`, `price` MOD 1 AS `p_decimal`
FROM
mytable
The problem is the results for p_decimal results is with "leading 0." and "4 decimal digits" instead of 2 :
0.2200
0.0000
0.5058
0.6700
SELECT
price,
CAST(price AS SIGNED) AS p_units,
LPAD(SUBSTRING_INDEX(price, '.', -1), 2, '0') AS p_decimals
FROM
YOUR_TABLE_NAME;
CAST(price AS SIGNED)
: This converts the price value into an integer by removing the decimals.
CAST(1020.2200 AS SIGNED)
-> 1020CAST(202.0000 AS SIGNED)
-> 202SUBSTRING_INDEX(price, '.', -1)
: Extract the part of the price after the decimal point.
SUBSTRING_INDEX(1020.2200, '.', -1)
-> 2200SUBSTRING_INDEX(202.0000, '.', -1)
-> 0000LPAD(..., 2, '0')
: Ensure the extracted value is at least 2 characters length by padding with zeros on the left.
LPAD('2200', 2, 0)
-> 22LPAD('6', 2, 0)
-> 60LPAD('0000', 2, 0)
-> 00
