如何在 BigQuery 中将数值转换为货币？

Question

I am new to BigQuery and am trying to convert numeric values (from Salesforce) to currency (preferably dollar value).

Very basically, what I have currently is:

SELECT salesforce.Name,
       ROUND(salesforce.Amount,2) as Amount 

FROM table.salesforce

Which obviously only rounds the value to two decimal places.

Answer 1

Regarding your question about how to convert a numeric value to currency value in BigQuery, I would advise you to use the FORMAT() and CONCAT() built-in functions.

I see that in your question you mentioned you want to round the numeric values to the second decimal place, you can do that using FORMAT() , you can read more about it here . In addition, to use the "$" sign, you can use CONCAT() . Below is an example where I used some dummy data to exemplify what I explained:

  WITH
  data AS (
  SELECT
    20.21 AS num
  UNION ALL
  SELECT
    99999999.12 AS num
  UNION ALL
  SELECT
    12345 AS num )
  SELECT
  CONCAT('$ ',FORMAT("%'.2f", num)) AS new_num
  FROM
  data

And the output:

Notice that in the FORMAT() function I used "%'.2f" , which rounds the number to the second decimal place. You can find more information about the meaning of each letter/number in the expression using the following guide .

As a bonus information, the currency values are formatted in a way that the dot "." is a decimal separator and the comma "," is a grouping separator. You can switch that using regex expressions with REGEX_REPLACE() and REPLACE() functions. If that is the case, just let me know so I can help.

Answer 2

This is the method that I use:

CAST(YourNumber AS STRING FORMAT '$999,999')

With decimal points:

CAST(YourNumber AS STRING FORMAT '$999,999.00')
