Subject: JSONB arrays

 

Hey people,

 

I ended up with the following to check (or similar to return) the intersection of two list of values on a JSONB object:

 

array_length(

array(

select jsonb_array_elements_text(col1)

intersect

select jsonb_array_elements_text(col2)

), 1) > 0

 

Is there a better way?

 

Thanks

 

 

Try the @> operator:

 

select '[1, 2, 3, 4]'::jsonb @> '[4, 2]'::jsonb

 

 

Steve.
