Stack Post-Filter with Project variable
Hey,
I have this project variable :
{
"filter_condition" : "timestamp>='2019-03-13' && timestamp<='2019-03-13')"
}
I want to use this variable on a Stack Post filter.
I tried to stack post filter using ${filter_condition} but i got this error :
An invalid argument has been encountered : Incorrect formula: '${filter_condition}' : Missing number, string, identifier, regex, or parenthesized expression(Parsing error at offset 0), caused by: ParsingException: Missing number, string, identifier, regex, or parenthesized expression(Parsing error at offset 0)
I also tried with "${filter_condition}" filter but it doesn't seem like its doing the job cauz im getting rows of 2019-04-14.

Hi,
I believe you need to change your variable syntax:
{ "filter_condition" : "'2019-03-13'" }And then in the recipe post-filter use a formula like:
timestamp >= asDate(${filter_condition}, "yyyy-MM-dd")You can also use this inside a Prepare recipe to create a column with your date variable and compute time difference inside the Prepare, which will make your Stack post-filter easier.
Hope this helps

Idk if i can really do that, because i may have multiple conditions to test for example
(timestamp>='2019-03-13T07:44:10.000000Z' && timestamp<='2019-03-13T09:44:10.000000Z') || (timestamp>='2019-03-19T12:28:43.000000Z' && timestamp<='2019-03-19T14:38:43.000000Z')

To do that you may need to create multiple variables and use a syntax like:
timestamp >= asDate(${date1}, "yyyy-MM-dd") ||timestamp <= asDate(${date2}, "yyyy-MM-dd").....In any case you cannot have a logical expression in your variable.
