1. A computer-implemented method for determining access of a query to privileged information, comprising: under the control of one or more computer systems configured with executable instructions, receiving a list of fully qualified privileged columns of a relational database, the columns having associated schema identifiers, table identifiers and column identifiers; receiving a database query; splitting the query into tokens; identifying potentially accessed columns from the tokens; generating a set of fully qualified columns by at least: generating possible combinations for potentially accessed columns that are unqualified by joining one or more unqualified potentially accessed columns with matching schema identifiers, table identifiers or column identifiers from the list of privileged columns to form a set of fully qualified potentially accessed columns; computing a determination of whether the query accesses a privileged column by determining if one or more columns from the set of fully qualified potentially accessed columns exist in the privileged columns; and returning a value indicating the computed determination.
