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='' 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='' 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='' 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=''

      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='' 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=''

    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
