Oracle NVL相当于SAS

Question

我需要将sql代码转换为sas代码;

  NVL(SPRTELE_STATUS_IND, 'A') = 'A' 
  AND NVL(SPRTELE_PRIMARY_IND, 'Y') = 'Y' 
  AND NVL(SPRTELE_SEQNO, 99) = 

    (SELECT NVL(MAX(SPRTELE_SEQNO), 99) 
   FROM SATURN.SPRTELE D 
  WHERE SPRIDEN_PIDM = D.SPRTELE_PIDM 
    AND D.SPRTELE_TELE_CODE = 'MA' 
    AND NVL(D.SPRTELE_STATUS_IND, 'A') = 'A' 
    AND NVL(D.SPRTELE_PRIMARY_IND, 'Y') = 'Y'))

如何将NVL转换为sas？那什么意识

Answer 1

正确的函数的使用,而不是NVL()为COALESCE().这是ANSI标准功能,由SAS,Oracle和大多数其他数据库支持:

  COALESCE(SPRTELE_STATUS_IND, 'A') = 'A' 
  AND COALESCE(SPRTELE_PRIMARY_IND, 'Y') = 'Y' 
  AND COALESCE(SPRTELE_SEQNO, 99) = 

    (SELECT COALESCE(MAX(SPRTELE_SEQNO), 99) 
   FROM SATURN.SPRTELE D 
  WHERE SPRIDEN_PIDM = D.SPRTELE_PIDM 
    AND D.SPRTELE_TELE_CODE = 'MA' 
    AND COALESCE(D.SPRTELE_STATUS_IND, 'A') = 'A' 
    AND COALESCE(D.SPRTELE_PRIMARY_IND, 'Y') = 'Y'))

完整查询中可能存在其他差异.
