#query all records not null in query convex

To query all records that are not null in Convex, you can use the filter method in your query. This method allows you to specify a condition that the records must meet to be included in the results. In this case, you would want to check that the field you are interested in is not null.
Here is an example of how you might do this, based on a Discord support thread:
export const getWaitingRoom = query({
args: {},
handler: async (ctx) => {
return await ctx.db.query("rooms").filter(room => room.capacity !== null).take(1);
},
});
In this example, the query is looking for rooms where the capacity field is not null. You would replace "rooms" with the name of your table and room.capacity with the field you want to check.
Remember that by default, Convex queries are full table scans, which is appropriate for prototyping and querying small tables. As your tables grow larger, you can improve your query performance by adding indexes. You can learn more about this in the Convex documentation on indexes (https://docs.convex.dev/database/indexes/).
Please note that this is a general guide and the exact code may vary depending on your specific use case and the structure of your data.
