CASE WHEN TYPE IN (1,2,3) AND NVL(PKG_TYPE,0) IN ('1','2','3','4','5','6') THEN 1 ELSE 0 END MAGICBOX_FUSION_ARR,在sql中,寻找语法错误

这个SQL片段看起来是在使用Oracle数据库的NVL函数和CASE WHEN语句进行条件判断。NVL函数用于返回NULL值的一个默认值，而CASE WHEN则是一个条件表达式，如果TYPE列的值在(1,2,3)范围内，并且PKG_TYPE列的值（如果有值的话）在('1','2','3','4','5','6')范围内，则返回1，否则返回0。

然而，语法上可能存在一些潜在的问题：

1. 检查括号是否匹配：IN关键字后的每个元素需要在括号内，即`(1,2,3)` 和 `('1','2','3','4','5','6')` 应该是圆括号包裹的。
2. NVL函数的第二个参数应该是数值，而不是字符串。如果PKG_TYPE可以是NULL，并且你希望它在NULL时被视为非空并参与比较，那么应该确保传入的是数字0作为默认值。
3. 如果TYPE列可能包含NULL值，CASE WHEN内部的条件可能需要处理这种情况，因为通常NULL不在IN运算符的范围内。

修正后的例子可能是这样的：

CASE 
   WHEN TYPE IN (1,2,3) 
   AND NVL(PKG_TYPE, 0) IN (1,2,3,4,5,6) THEN 1 
   ELSE 0 
END AS MAGICBOX_FUSION_ARR,

CREATE TABLE TEST_ZHANG_0518_1 AS SELECT A.CAMP_ID, SUM(A.income_year) AS income_year, -- 年累出账收入 SUM(A.INCOME_END) AS INCOME_END, -- 去年12月出账月收入 -- 拍照移网用户出账 SUM(CASE WHEN A.PRODUCT_FLAG IN ('1','2','3') AND A.ACCT_TAG_END='1' AND A.ACCT_TAG='1' THEN 1 ELSE 0 END) AS PZ_YW_ACT_NEW, SUM(CASE WHEN A.PRODUCT_FLAG IN ('1','2','3') AND A.ACCT_TAG_END='1' THEN 1 ELSE 0 END) AS PZ_YW_ACT_OLD, -- 拍照宽带用户在网 SUM(CASE WHEN A.PRODUCT_FLAG IN ('4') AND A.ON_TAG_END='1' AND A.ON_TAG='1' THEN 1 ELSE 0 END) AS PZ_KD_ONS_NEW, SUM(CASE WHEN A.PRODUCT_FLAG IN ('4') AND A.ON_TAG_END='1' THEN 1 ELSE 0 END) AS PZ_KD_ONS_OLD FROM DWD_M_PRO_YF_USER_FS A WHERE A.DEAL_MON='202305' AND NVL(A.ON_TAG_END,'0')<>'-1' -- 拍照用户 GROUP BY A.CAMP_ID;

这是一个创建表的SQL语句，表名为TEST_ZHANG_0518_1，该表从DWD_M_PRO_YF_USER_FS表中选取特定月份（202305）的数据，并按照CAMP_ID字段进行分组。在分组后的结果中，对income_year字段进行求和，得到年累出账收入；对INCOME_END字段进行求和，得到去年12月出账月收入；对满足特定条件的PZ_YW_ACT_NEW、PZ_YW_ACT_OLD、PZ_KD_ONS_NEW和PZ_KD_ONS_OLD字段进行统计。其中，PZ_YW_ACT_NEW表示拍照移网用户中当月激活的新用户数量，PZ_YW_ACT_OLD表示拍照移网用户中当月激活的老用户数量，PZ_KD_ONS_NEW表示拍照宽带用户中当月在网的新用户数量，PZ_KD_ONS_OLD表示拍照宽带用户中当月在网的老用户数量。

首先，可以将子查询中的所有列名改为别名，这样可以避免重名和提高代码可读性。另外，可以尝试使用 EXISTS 子查询来替换 NOT EXISTS 子查询，因为 EXISTS 子查询的性能通常更好。最后，可以考虑对 WHERE 子句中的多个条件进行逻辑上的分组，以避免出现过于复杂的条件表达式。下面是优化后的 SQL：
