將預先連接的表格與另一個表格結合起來

我正嘗試與另一個表格並排連接預先連接的表格，但似乎無法正常工作。將預先連接的表格與另一個表格結合起來

下面的代碼：

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

也有一些是錯誤的，在這條線

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

這裏的錯誤：

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

最後，我想有一個表中，它有，"domainid, domainstart, domainend, ddid, confid, chainid, pdbcode from conformer and the chain id"和沿着一邊，我想有一組新的列另一個表，如"pdbcode from cath_domains, cathbegin, cathend"。

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

我在做錯誤的方式嗎？

停止執行隱式交叉連接。另外ypercube指出，還需要清理其他一些小東西，特別是刪除重複的連接。

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

FROM dyn_dyndomrun d 
    INNER JOIN dyn_conformer c ON d.confid2 = c.id 
    ORDER BY confid ASC
