Unable to parse large complicated query (parenthesis problem) #152

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago
What steps will reproduce the problem?
1. Use this query:
SELECT COUNT(*) AS Result
FROM 
    rbac_userroles AS TUrel 

    JOIN rbac_roles AS TRdirect ON (TRdirect.ID=TUrel.RoleID)
    JOIN rbac_roles AS TR ON ( TR.Lft BETWEEN TRdirect.Lft AND TRdirect.Rght)
    /* we join direct roles with indirect roles to have all descendants of direct roles */
    JOIN
    (   rbac_permissions AS TPdirect
    JOIN rbac_permissions AS TP ON ( TPdirect.Lft BETWEEN TP.Lft AND TP.Rght)
    /* direct and indirect permissions */
    JOIN rbac_rolepermissions AS TRel ON (TP.ID=TRel.PermissionID)
    /* joined with role/permissions on roles that are in relation with these permissions*/
    ) ON ( TR.ID = TRel.RoleID)
    WHERE
    /* TU.ID=? */
    TUrel.UserID=?
    AND
    TPdirect.ID=?

What is the expected output? What do you see instead?
This is what's causing trouble:
    JOIN
    (   rbac_permissions AS TPdirect
    JOIN rbac_permissions AS TP ON ( TPdirect.Lft BETWEEN TP.Lft AND TP.Rght)
    /* direct and indirect permissions */
    JOIN rbac_rolepermissions AS TRel ON (TP.ID=TRel.PermissionID)
    /* joined with role/permissions on roles that are in relation with these permissions*/
    ) ON ( TR.ID = TRel.RoleID)

If I replace it with:
    JOIN
    rbac_permissions AS TPdirect
    JOIN rbac_permissions AS TP ON ( TPdirect.Lft BETWEEN TP.Lft AND TP.Rght)
    /* direct and indirect permissions */
    JOIN rbac_rolepermissions AS TRel ON (TP.ID=TRel.PermissionID)
    /* joined with role/permissions on roles that are in relation with these permissions*/

it works well.

What version of the product are you using? On what operating system?
Latest, on OS X Yosemite.

Please provide any additional information below.

This is a valid MySQL query (used in PhpRbac package).
