ORACLE 多列合并成一行数据 WM_CONCAT函数以及REPLACE

WM_CONCAT()方法 注意字符长度

SELECT BERTHCODE,tpf.freedatetype,
( SELECT  WM_CONCAT(SBPT.PARKSTIME||'~'||SBPT.PARKETIME) SAREE FROM  
SYS_BERTHANDTYPE SBT LEFT JOIN  SYS_BERTHTYPEPARKTIME SBPT  
ON SBT.BERTHTYPEID = SBPT.BERTHTYPEID WHERE BERTHCODE='114163' AND 
 SBPT.DATETYPE = 1 AND  SBPT.ISALLOW = 2)  
 NOTALLOWTIMESPAN, WM_CONCAT(SUBSTR(TO_CHAR(FREESTARTTIME,'YYYY-MM-DD HH24:MI:SS'),11,9)||'~'||SUBSTR(TO_CHAR(FREEENDTIME,'YYYY-MM-DD HH24:MI:SS'),11,9)) 
 FREETIMESPAN 
  FROM TRA_PRICINGBERTH  TPB LEFT JOIN TRA_PRICINGFREE TPF  ON TPB.PRICINGSTRATEGYID = TPF.PRICINGSTRATEGYID 
 WHERE BERTHCODE='114163' AND FREEDATETYPE=1 GROUP BY BERTHCODE,tpf.freedatetype
 order by BERTHCODE

 

 可以使用以下这个方法REPLACE(WM_CONCAT())

SELECT  TPB.BERTHCODE, ( 
   SELECT  REPLACE(WM_CONCAT(SBPT.PARKSTIME||'~'||SBPT.PARKETIME)OVER (PARTITION BY BERTHCODE,SBPT.PARKETIME), ',', ';')
    AS SAREE FROM  SYS_BERTHANDTYPE SBT   
   LEFT JOIN  SYS_BERTHTYPEPARKTIME SBPT ON SBT.BERTHTYPEID = SBPT.BERTHTYPEID 
        WHERE SBT.BERTHCODE='114163' AND  SBPT.DATETYPE = 1 AND  SBPT.ISALLOW =2
         ) AS NOTALLOWTIMESPAN ,
        
    REPLACE(WM_CONCAT(SUBSTR(TO_CHAR(FREESTARTTIME,'YYYY-MM-DD HH24:MI:SS'),11,9)
         ||'~'||SUBSTR(TO_CHAR(FREEENDTIME,'YYYY-MM-DD HH24:MI:SS'),11,9)), ',', ';')
         AS  FREETIMESPAN 
         
         FROM TRA_PRICINGBERTH  TPB 
         LEFT JOIN TRA_PRICINGFREE TPF  ON TPB.PRICINGSTRATEGYID = TPF.PRICINGSTRATEGYID 
        WHERE 
       TPB.BERTHCODE='114163'  
      AND TPF.FREEDATETYPE=1  
        GROUP BY BERTHCODE

如果遇到版本问题 在Oracle11G下可以使用以下方法 LISTAGG()

SELECT  TPB.BERTHCODE, ( SELECT  LISTAGG( (SBPT.PARKSTIME||'~'||SBPT.PARKETIME), '; ' ) WITHIN GROUP (ORDER BY SBPT.PARKTIMEID)
 AS SAREE  FROM SYS_BERTHANDTYPE SBT
LEFT JOIN  SYS_BERTHTYPEPARKTIME SBPT ON SBT.BERTHTYPEID = SBPT.BERTHTYPEID 
      WHERE SBT.BERTHCODE='114163' AND  SBPT.DATETYPE = 1 AND  SBPT.ISALLOW =2
      ) AS NOTALLOWTIMESPAN ,
      LISTAGG(SUBSTR(TO_CHAR(FREESTARTTIME,'YYYY-MM-DD HH24:MI:SS'),11,9)
       ||'~'||SUBSTR(TO_CHAR(FREEENDTIME,'YYYY-MM-DD HH24:MI:SS'),11,9), '; ')WITHIN GROUP (ORDER BY TPF.FREEID)
       AS  FREETIMESPAN       
       FROM TRA_PRICINGBERTH  TPB 
       LEFT JOIN TRA_PRICINGFREE TPF  ON TPB.PRICINGSTRATEGYID = TPF.PRICINGSTRATEGYID 
      WHERE 
     TPB.BERTHCODE='114163'  
    AND TPF.FREEDATETYPE=1  
      GROUP BY BERTHCODE

 

 

 

WM_CONCAT 合并成一行数据列 数据量大会超出字符长度

SELECT wm_concat(sbpt.ParkStime||'~'||sbpt.ParkEtime) FROM SYS_BerthTypeParkTime sbpt

REPLACE 分成多列

SELECT  REPLACE(sbpt.ParkStime||'~'||sbpt.ParkEtime,',')
 FROM SYS_BerthTypeParkTime sbpt
