600 Errors

Problem

My FQL doesn’t work! I’m getting a 600 error!

Solution

Don’t panic! 600-class errors are Facebook’s way of telling you that there’s something wrong with your FQL query. The possible error codes are listed in Table 8-19.

Table 8-19. FQL error codes

Error code	Description
601	Error while parsing the FQL statement.
602	The field you requested does not exist.
603	The table you requested does not exist.
604	Your statement is not indexable.
605	The function you called does not exist.
606	Wrong number of arguments passed into the function.

Discussion

Pay special attention to 604 errors, because they often have extra information in them about why the statement isn’t indexable. As an example, metrics table queries are considered indexable only if the date range you’re querying on isn’t bigger than 30 days. If it is bigger, you’ll get a 604 error, which tells you that the range is too big.

If you’re getting an error and are having trouble tracking it down in the context of your code, try extracting the query and running it directly inside the API Test Console at http://developers.facebook.com/tools.php?api. If you select “fql.query” as the Method, you can play with FQL and see live results on the righthand side.
