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
