Hi Sreenu, Thank you for your query. I see that you're putting the incorrect field in the "FROM" clause. I've written an example query for you below that you can populate with fields from this document.
"SELECT operating_system_version_constant.id, operating_system_version_constant.name, operating_system_version_constant.os_major_version, operating_system_version_constant.os_minor_version FROM operating_system_version_constant" You can see that the FROM clause is pulling from the operating system version constant report type. Let me know if you have further questions.
