運行oracle sql查詢加入約10個表時出現ORA-01652錯誤

Question

我在oracle上有三個用戶，他們有相同的表空間，當我運行下面的查詢時，我在執行查詢時遇到以下問題。而且在執行需要一個地獄很多時間:(

ORA-01652: unable to extend temp segment by 128 in tablespace TEMP 
01652. 00000 - "unable to extend temp segment by %s in tablespace %s" 
*Cause: Failed to allocate an extent of the required number of blocks for 
     a temporary segment in the tablespace indicated. 
*Action: Use ALTER TABLESPACE ADD DATAFILE statement to add one or more 
     files to the tablespace indicated.

如果不知何故此查詢可以再優化的建議是最受大家歡迎的

嘗試使用CTE。除此之外，你應該使用SQL ANSI-Syntax，通常它更容易閱讀。

你與表db1.nbfc_parameter_m交叉連接。是否有意？

with c as 
(SELECT x.AGREEMENTID,  
     COUNT (1) AS balancetenure,  
     TO_CHAR (SUM(NVL(PRINCOMP,0)),'999,999,999,999,999,900.00')  
    FROM db1.LEA_REPAYSCH_DTL x

    RIGHT OUTER JOIN db1.NBFC_PRODUCT_M c ON A.productflag  = c.code

也許我是混合RIGHT OUTER JOIN和LEFT OUTER JOIN，我不再使用舊的Oracle連接語法。
