我想你solId是为了solitications。我本来以为它是固体（像一块岩石）。因此，这可以通过合成来完成。

请注意，提供的架构中存在一些输入错误。一些逗号缺失，一些索引名称重复。MyISAM表更改为INNODB。所以我做了一些重命名。另外，在table5周围缺少表。因此，就好像您的脚本不会运行（用于table
rfqs）。

类似地，由于提供的表丢失，以下模式将失败，该表大约占整个表的60％到70％。

compTableX001就像一个名称为的TwoParents-
OneChild迷你层次结构ID。ID父母的名字也是如此。它有两个父母（BaseRFQId和SolId）和一个孩子（NSNId）。名称或标识符as
ID为baserfqssols它支持的行的FK目标。 引用 和 引用 。

同样，compTableX002似乎可以解决问题2的条件。
