MySQL Recursive CTE - Date Range Split



I am having trouble setting up a recursive CTE with MySQL dataflows, I have seen various articles on recursive dataflows on Domo but do not think they will be much help here, so I am turning to SQL. We currently have budgets corresponding to different campaigns over various date ranges. And example of this is below:


Campaign X | Daily Budget | Start Date | End Date


The idea would be to convert it to show like this


Date | Campaign X | Start Date | End Date | Daily Budget


Where date is every day in the Start and End Date range, I currently have this query in an output dataset in the MySQL dataflow:


WITH cte AS (
SELECT `Campaign Name`, `Start date`,`End date`
FROM `Budgets'
SELECT `Campaign Name`, DATEADD(day, 1, `Start date`), `End date`
FROM cte
WHERE `Start date` <= `End date`


I get the following error message "The database reported a syntax error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'cte AS ( SELECT `Campaign Name`, `Start date`,`End date` FROM' at line 1"


Any help would be greatly appreciated! Thanks

    If you SELECT VERSION() you'll see which version of MySQL you're developing against, MySQL 5.6, 


    MySQL 5.6 does not support CTEs :(


    But if you have a list of Dates (a date dimension) you could accomplish the same thing with a simple JOIN







    Date d

    on between startDate and endDate


    or similar.

  • Wow thanks a lot, this did what I needed it to do perfectly, and much much simpler than trying to write a recursive CTE in the first place! Thanks a lot for the help
