+     * Gets SQL that can be used in a query to get the necessary fields.
+     *
+     * The result of this function is an object with fields 'selects', 'joins', 'params', and
+     * 'mappings'.
+     *
+     * If not empty, the list of selects will begin with a comma and the list of joins will begin
+     * and end with a space. You can include the result in your existing query like this:
+     *
+     * SELECT (your existing fields)
+     *        $selects
+     *   FROM {user} u
+     *   JOIN (your existing joins)
+     *        $joins
+     *
+     * When there are no custom fields then the 'joins' result will always be an empty string, and
+     * 'params' will be an empty array.
+     *
+     * The $fieldmappings value is often not needed. It is an associative array from each field
+     * name to an SQL expression for the value of that field, e.g.:
+     *   'profile_field_frog' => 'uf1d_3.data'
+     *   'city' => 'u.city'
+     * This is helpful if you want to use the profile fields in a WHERE clause, becuase you can't
+     * refer to the aliases used in the SELECT list there.
+     *
+     * The leading comma is included because this makes it work in the pattern above even if there
+     * are no fields from the get_sql() data (which can happen if doing identity fields and none
+     * are selected). If you want the result without a leading comma, set $leadingcomma to false.
+     *
+     * If the 'id' field is included then it will always be first in the list. Otherwise, you
+     * should not rely on the field order.
+     *
+     * For identity fields, the function does all the required capability checks to see if the
+     * current user is allowed to see them in the specified context. You can pass context null
+     * to get all the fields without checking permissions.
+     *
+     * If your code for any reason cannot cope with custom fields then you can turn them off.
+     *
+     * You can have either named or ? params. If you use named params, they are of the form
+     * uf1s_2; the first number increments in each call using a static variable in this class and
+     * the second number refers to the field being queried. A similar pattern is used to make
+     * join aliases unique.
+     *
+     * If your query refers to the user table by an alias e.g. 'u' then specify this in the $alias
+     * parameter; otherwise it will use {user} (if there are any joins for custom profile fields)
+     * or simply refer to the field by name only (if there aren't).
+     *
+     * If you need to use a prefix on the field names (for example in case they might coincide with
+     * existing result columns from your query, or if you want a convenient way to split out all
+     * the user data into a separate object) then you can specify one here. For example, if you
+     * include name fields and the prefix is 'u_' then the results will include 'u_firstname'.
+     *
+     * If you don't want to prefix all the field names but only change the id field name, use
+     * the $renameid parameter. (When you use this parameter, it takes precedence over any prefix;
+     * the id field will not be prefixed, while all others will.)
+     *
+     * @param string $alias Optional (but recommended) alias for user table in query, e.g. 'u'
+     * @param bool $namedparams If true, uses named :parameters instead of indexed ? parameters
+     * @param string $prefix Optional prefix for all field names in result, e.g. 'u_'
+     * @param string $renameid Renames the 'id' field if specified, e.g. 'userid'
+     * @param bool $leadingcomma If true the 'selects' list will start with a comma
