将预先连接的表格与另一个表格结合起来

我正尝试与另一个表格并排连接预先连接的表格，但似乎无法正常工作。将预先连接的表格与另一个表格结合起来

下面的代码：

SELECT 
    r.domainid, 
    r.dombegin AS DomainStart, 
    r.domend AS Domain_End, 
    d.ddid, 
    d.confid1 AS confid, 
    c.pdbcode, 
    c.chainid, 
    a.pdbcode AS "cath_pdbcode", 
    c.pdbcode 
FROM dyn_dyndomrun d, cath_domains a 
    INNER JOIN dyn_conformer c ON d.confid1 = c.id 
    INNER JOIN dyn_domainregion r ON r.domainid::varchar(8) = d.ddid 
    INNER JOIN dyn_conformer AS c ON a.pdbcode::character(4) = c.pdbcode 
UNION ALL 
SELECT 
    NULL, 
    NULL, 
    NULL, 
    NULL, 
    NULL, 
    d.ddid, 
    d.confid2, 
    c.pdbcode, 
    c.chainid 
FROM dyn_dyndomrun d 
    INNER JOIN dyn_conformer c ON d.confid2 = c.id 
    ORDER BY confid ASC

也有一些是错误的，在这条线

FROM dyn_dyndomrun d, cath_domains a 
     INNER JOIN dyn_conformer c ON d.confid1 = c.id 
     INNER JOIN dyn_domainregion r ON r.domainid::varchar(8) = d.ddid 
     INNER JOIN dyn_conformer AS c ON a.pdbcode::character(4) = c.pdbcode

这里的错误：

ERROR: invalid reference to FROM-clause entry for table "d" 
LINE 11: INNER JOIN dyn_conformer c ON d.confid1 = c.id 
             ^
HINT: There is an entry for table "d", but it cannot be referenced from this part of the query. 


********** Error ********** 

ERROR: invalid reference to FROM-clause entry for table "d" 
SQL state: 42P01 
Hint: There is an entry for table "d", but it cannot be referenced from this part of the query. 
Character: 236

最后，我想有一个表中，它有，"domainid, domainstart, domainend, ddid, confid, chainid, pdbcode from conformer and the chain id"和沿着一边，我想有一组新的列另一个表，如"pdbcode from cath_domains, cathbegin, cathend"。

来自conformer和cath_domains的pdbcode相互匹配，因此我想交叉引用它们。

我在做错误的方式吗？

停止执行隐式交叉连接。另外ypercube指出，还需要清理其他一些小东西，特别是删除重复的连接。

SELECT 
    r.domainid, 
    r.dombegin AS DomainStart, 
    r.domend AS Domain_End, 
    d.ddid, 
    d.confid1 AS confid, 
    c.pdbcode, 
    c.chainid, 
    a.pdbcode AS "cath_pdbcode", 
    c.pdbcode 
FROM dyn_dyndomrun d 
    INNER JOIN dyn_conformer c ON d.confid1 = c.id 
    INNER JOIN dyn_domainregion r ON r.domainid::varchar(8) = d.ddid 
    INNER JOIN cath_domains a ON a.pdbcode::character(4) = c.pdbcode
