ADF : How to check if JSON array contains particular string - azure

Question

Here is some sample data provided by a cosmosdb which contains JSON :
[
{
"Name":"ABC",
"ID":20,
"Category":"IT",
"training_cycles": [
"Jan 01, 2022 → Jun 30, 2022",
"Jul 01, 2021 → Dec 31, 2021"
]
},
{
"Name":"John",
"ID":25,
"Category":"Comp",
"training_cycles": [
"Jan 01, 2022 → Jun 30, 2022"
]
},
{
"Name":"XYZ",
"ID":23,
"Category":"HR",
"training_cycles": [
"Jan 01, 2022 → Jun 30, 2022"
]
}
]
Id like to ask azure data factory to select items which contain "Jul 01, 2021 → Dec 31, 2021" within "training_cycles".
So far, in my data flow, i have selected all my items and filtered to only see training_cycles... so my data only has 1 "column" called training_cycles and many items which contain these training_cycles.
I tried filtering with :
contains(training_cycles, "#training_cycles" == "Jul 01, 2021 → Dec 31, 2021")
but it selects all the data instead of only the items which contain the right data.
Thanks for the help

Answer 1

I tried to reproduce your issue.
My sample json
[
{
"Name":"ABC",
"ID":20,
"Category":"IT"
},
{
"Name":"John",
"ID":25,
"Category":"Comp"
},
{
"Name":"XYZ",
"ID":23,
"Category":"HR"
}
]

Then I used Filter Row Modifier. Here In Filter On condition I used Name==’ABC’. In your case you can use training_cycles == "Jul 01, 2021 → Dec 31, 2021"
