Hi venky,
I want to promote only class 8 student to 9
when I try below code it is updating all the students.
a!localVariables( local!a: { a!map(name: "X", class: 5, School: "ABC"), a!map(name: "Y", class: 6, School: "ADC"), a!map(name: "Z", class: 7, School: "AEC"), a!map(name: "K", class: 8, School: "AFC") }, a!forEach( items: local!a, expression: a!update( data: fv!item, index: "class", value: 9 ) ) )
Thanks in Advance
a!update(local!X[4],"class",9)
In case you don't know the index, just add the value you want to update in the where contains and it should work.
a!update( data: local!var[wherecontains(8,local!var.class)], index: "class", value: 9 )
