Techniques and solutions are described for facilitating the determination of whether a query, such as a database query, may raise a compliance issue, such as whether restricted information associated with a particular database field is provided as an output of the query. A compliance tool receives a query that includes a plurality of query operations. At least one database field associated with a potential compliance issue is received. For example, the at least one database field may be associated with restricted information. The plurality of query operations are analyzed to determine whether information associated with the at least one database field is an output of the query to provide compliance results. The compliance results are output to a user.
