Determine the upcoming Saturday's date by utilizing a stored procedure in Snowflake

Looking for assistance in retrieving the upcoming Saturday date based on a date field in a table using a Snowflake JavaScript stored procedure. Any suggestions would be greatly appreciated.

Running the following query in the Snowflake console provides the desired result:

SELECT next_day(TO_DATE(MAX(SALE_DATE)),'Saturday') FROM Sales;

However, upon attempting to implement the same logic within a stored procedure, an error is encountered stating "unexpected Saturday."

I have made an attempt to retrieve the upcoming Saturday date based on the maximum date in the table.

var get_cm = "SELECT next_day(TO_DATE(MAX(SALE_DATE)),'Saturday') FROM Sales";
var get_sql= snowflake.createStatement({sqlText:get_cm);
var res_dt = get_sql.execute();
res_dt.next();
var res = res_dt.getColumnValue(1);
return res;

Answer №1

After making some adjustments to your JavaScript code, I managed to get it up and running successfully:

UPDATE OR INSERT procedure UPCOMING_SATURDAY_TEST()
RETURNS VARCHAR
LANGUAGE JAVASCRIPT
AS
$$
   var query = "SELECT next_day(TO_DATE(MAX(PURCHASE_DATE)),'Saturday') FROM Purchases;";
   var result_set = snowflake.execute({sqlText: query});
   result_set.next();
   var output = result_set.getColumnValue(1);
   return output;
$$;

Here's a step-by-step guide to follow:

  1. Determine the day of the week for your specified input date
  2. Calculate the difference between this day and Saturday using customizable parameters like WEEK_START
  3. Take this resulting number of days and add it to your original input date
