NetSuite SQL情况时

Question

我试图在NetSuite保存的搜索中编写SQL查询，如果满足某些条件，则返回文本值，如果不满足，则移至下一个CASE WHEN语句。这是我所拥有的：L

CASE WHEN {shipstate} IN ('AK','ID','MT','OR','WA') THEN 'Northwest' 
ELSE CASE WHEN {shipstate} IN ('CA','HI','NV','AZ') THEN 'West' 
ELSE CASE WHEN {shipstate} IN ('CO','NM','UT','WY') THEN 'Rockies' 
ELSE CASE WHEN {shipstate} IN ('AR','KS,'LA','OK','TX') THEN 'SO Central' 
ELSE CASE WHEN {shipstate} IN ('IN','KY','MI','OH') THEN 'Great Lakes' 
ELSE CASE WHEN {shipstate} IN ('IA','IL','MN','MO','NE','ND','SD','WI') THEN 'Midwest' 
ELSE CASE WHEN {shipstate} IN ('CT','MA','ME','NH','RI','VT') THEN 'Northeast' 
ELSE 'Southeast' 
END END END END END END END

我不确定是否在错误的位置插入了ENDS，但是我确实早先使用了2个CASE WHEN语句。任何帮助，将不胜感激。

Answer 1

when在case语句中可以有多个子句，因此只需要一个case和一个end，就像这样：

CASE 
    WHEN {shipstate} IN (
        'AK','ID','MT','OR','WA'
        ) THEN 'Northwest' 
    WHEN {shipstate} IN (
        'CA','HI','NV','AZ'
        ) THEN 'West' 
    WHEN {shipstate} IN (
        'CO','NM','UT','WY'
        ) THEN 'Rockies' 
    WHEN {shipstate} IN (
        'AR','KS','LA','OK','TX'
        ) THEN 'SO Central' 
    WHEN {shipstate} IN (
        'IN','KY','MI','OH'
        ) THEN 'Great Lakes' 
    WHEN {shipstate} IN (
        'IA','IL','MN','MO','NE','ND','SD','WI'
        ) THEN 'Midwest' 
    WHEN {shipstate} IN (
        'CT','MA','ME','NH','RI','VT'
        ) THEN 'Northeast' 
    ELSE 'Southeast' 
END

顺便说一句，您忘记了'您的IN情况之一。
