我在 Oracle 11g 中有 3 个字段的表:
STUDYID | STUDY_PARAMETER | STUDY_VALUE
5268 | Age Group | ADULT (18-65)
5269 | Age Group | ADULT (18-65)
5270 | Age Group | ADULT (18-65)
5271 | Age Unit | ADULT (18-65)
1668A | Trial Type | ADULT (18-65)
5273 | Trial Type | Dispensing
5345 | Age Unit | Years
1668AC | Age Group | ADULTS (18-39)
所以,我需要按以下顺序显示值:
STUDY_ID | AGE_GROUP | AGE_UNIT | TRIAL_TYPE
5268 | ADULT (18-65) | Years | Dispensing
5269 | ADULT (18-65) | (null) | (null)
1668AC | ADULTS (18-39)| Years | Non - Dispensing
等等。
到目前为止,我所拥有的是:
SELECT *
FROM (
SELECT STUDYID, STUDY_VALUE, STUDY_PARAMETER
FROM RD.STUDY_INFO
)
PIVOT (
SUM(STUDY_VALUE)
FOR (STUDY_PARAMETER)
IN (
'Age Unit' AS AGE_UNIT,
'Age Group' AS AGE_GROUP,
'Trial Type' AS TRIAL_TYPE
)
);
我从网上的例子中学到了这一点,但我不确定我是否可以像这样使用 SUM() ......?!
我收到此错误:
ORA-01722: invalid number
01722. 00000 - "invalid number"
有谁看到我做错了什么?
