title: Amazon Athena- Querying columns with numbers stored as string
body: <p>I have a insurance dataset which includes the number of enrollment for each county. However the number of enrollments is stored as a string. How can i query the data for something like "Find the plans which have a enrollment of more than 50". Unfortunately 50 is stored as a string in the dataset so i need to understand how to run my query using athena. Can someone help please</p>
