Will this clean the data? OR just select the data?

No cleanup just select and return .
instead of passing a sting you can pass the column name but if you want then you can use replacing too like :

## Selecting data

SELECT select uExtractNumberFromString(columnname) FROM table_name WHERE condition;

## For replacing
UPDATE table_name
SET columname = uExtractNumberFromString(columnname);

for updating entire table and for updating columns based on condition then

UPDATE table_name
SET columname = uExtractNumberFromString(columnname)
WHERE condition;
