我有两个简单的表:

CREATE TABLE cat_urls (
  Id int(11) NOT NULL AUTO_INCREMENT,
  SIL_Id int(11) NOT NULL,
  SiteId int(11) NOT NULL,
  AsCatId int(11) DEFAULT NULL,
  Href varchar(2048) NOT NULL,
  ReferrerHref varchar(2048) NOT NULL DEFAULT '',
  AddedOn datetime NOT NULL DEFAULT CURRENT_TIMESTAMP,
  GroupId int(11) DEFAULT NULL,
  PRIMARY KEY (Id),
  INDEX SIL (SIL_Id, AsCatId)
)

CREATE TABLE products (
  Id int(11) NOT NULL AUTO_INCREMENT,
  CatUrlId int(11) NOT NULL,
  Href varchar(2048) NOT NULL,
  SiteIdentity varchar(2048) NOT NULL,
  Price decimal(12, 2) NOT NULL,
  IsAvailable bit(1) NOT NULL, …
