带连续列的SQL CASE

Question

我试图从不同列的数据串联中找到一个子串，并根据结果返回一个值。 我已经试过此查询：

SELECT 
    V_CMR_1.*, 
    T_RICEVITORI.*, 
    CASE 
     WHEN contains(V_CMR_1.SP1C || ' ' || V_CMR_1.SP2C || ' ' || V_CMR_1.SP3C || ' ' || V_CMR_1.SP4C || ' ' || V_CMR_1.SP5C, 'GIALLA') > 0 THEN 'GELBE' 
     WHEN contains(V_CMR_1.SP1C || ' ' || V_CMR_1.SP2C || ' ' || V_CMR_1.SP3C || ' ' || V_CMR_1.SP4C || ' ' || V_CMR_1.SP5C, 'ROSSA') > 0 THEN 'ROTE' 
     END AS SORTE 
FROM 
    MAGAZZINO.V_CMR_1, 
    MAGAZZINO.T_RICEVITORI 
WHERE 
    V_CMR_1.ID_RICEVITORE=T_RICEVITORI.ID_RICEVITORE 
    AND V_CMR_1.ID_USCITA=:IDUSCITA 
    AND V_CMR_1.ID_POSIZIONE LIKE :ANNO 

但我越来越怪异的Oracle错误（档案结尾通信信道）。 它会工作吗？

谢谢！

尝试instr函数，而不是contains

SELECT V_CMR_1.*, 
     T_RICEVITORI.*, 
     CASE WHEN instr(V_CMR_1.SP1C || ' ' || V_CMR_1.SP2C || ' ' || V_CMR_1.SP3C || ' ' || V_CMR_1.SP4C || ' ' || V_CMR_1.SP5C, 'GIALLA') > 0 THEN 'GELBE' 
      WHEN instr(V_CMR_1.SP1C || ' ' || V_CMR_1.SP2C || ' ' || V_CMR_1.SP3C || ' ' || V_CMR_1.SP4C || ' ' || V_CMR_1.SP5C, 'ROSSA') > 0 THEN 'ROTE' 
     END AS SORTE 
FROM MAGAZZINO.V_CMR_1, MAGAZZINO.T_RICEVITORI 
WHERE V_CMR_1.ID_RICEVITORE=T_RICEVITORI.ID_RICEVITORE 
AND V_CMR_1.ID_USCITA=:IDUSCITA AND V_CMR_1.ID_POSIZIONE LIKE :ANNO
