[Parameters=[], CommandType='Text', CommandTimeout='30']

CREATE TABLE `AspNetUserRoles` (
    `UserId` varchar(767) NOT NULL,
    `RoleId` varchar(767) NOT NULL,
    PRIMARY KEY (`UserId`, `RoleId`),
    CONSTRAINT `FK_AspNetUserRoles_AspNetRoles_RoleId` FOREIGN KEY (`RoleId`) REFERENCES `AspNetRoles` (`Id`) ON DELETE CASCADE,
    CONSTRAINT `FK_AspNetUserRoles_AspNetUsers_UserId` FOREIGN KEY (`UserId`) REFERENCES `AspNetUsers` (`Id`) ON DELETE CASCADE
);
