I have a column called' memo_line_2',the value format is like :'$3000.00 (card limit increase)',how can I only extract numeric value from the column?Thanks example:
'$3000.00 (card limit increase)' -> 3000
'$5000.00 (card limit increase)' -> 5000
'$12000.00 (card limit increase)' ->12000
You could use REGEXP_SUBSTR()
for this:
SELECT REGEXP_SUBSTR(tmp.`value`, '[0-9]+') as `new_value`
FROM (SELECT '$3000.00' as `value` UNION ALL
SELECT '$5000.00' as `value` UNION ALL
SELECT '$12000.00' as `value`) tmp
Returns:
new_value
---------
3000
5000
12000
If you would like to keep everything after the decimal, use '[0-9.]+'
as your regular expression filter.
If your data will be always in this format you can use below query to select the data between $
and .
:
SELECT substring_index(substring_index(memo_line_2, '$', -1), '.', 1)
FROM your_table;
Refrence: MySQL substring between two strings
You can use:
select regexp_substr(col, '[0-9]+[.]?[0-9]*')
This will extract the digits with the cents. You can then convert to an integer or numeric:
select cast(regexp_substr(col, '[0-9]+[.]?[0-9]*') as unsigned)
It can be done by making a custom function in your sql query
