(case when (substr(d.hy_dm,1,2)>=06 and substr(d.hy_dm,1,2)<=43) or substr(d.hy_dm,1,2)='71' or substr(d.hy_dm,1,2) in('51','52') then 0.13 when substr(d.hy_dm,1,2) in('01','02','03','04','05','44','45','46','47','48','49','50','53','54','55','56','57','60','63','70') then 0.09 else 0.06 end) 翻译此段代码

这段代码是一个SQL语句中的CASE语句，用于根据d.hy_dm的值返回不同的结果。如果d.hy_dm的前两位数字在06到43之间，或者是71，或者是51或52，则返回0.13；如果d.hy_dm的前两位数字在01到05，44到50，53到57，60，63或70之间，则返回0.09；否则返回0.06。其中substr函数用于截取d.hy_dm的前两位数字。

以上代码语法没有错误，但是在 `JOIN` 子句中，需要将 `IN` 操作符后面的两个参数之间的中文逗号改为英文逗号。修改后的代码如下：

SELECT C.HY_DM,
       C.HYMC,
       MAX(CASE WHEN XSE.ND = '2021' THEN SUM(XSE.XSE) END) XSE_2021,

优化一下此sql，select count(1) "笔数",trunc(SUM(A.JYJE)/10000,2) "金额/万元" from SKY.JY_RKLS A where a.dcpzlx_dm = '1' and substr(A.YSKM_DM,0,7) = '1010602' and A.JYJE >= 0 and substr(A.PZHM , 0,1) = '6' and A.Date >= DATE '2023-03-01';

可以考虑如下优化：

1. 将 WHERE 子句中的 A.JYJE >= 0 改为 A.JYJE > 0，这样可以避免将值为 0 的记录也计入结果中。

2. 将 WHERE 子句中的 substr(A.PZHM, 0, 1) = '6' 改为 A.PZHM LIKE '6%'，这样可以使用索引快速定位符合条件的记录。

3. 将 WHERE 子句中的 A.Date >= DATE '2023-03-01' 改为 A.Date >= TO_DATE('2023-03-01', 'YYYY-MM-DD')，这样可以避免强制转换导致的性能损失。

综上所述，优化后的 SQL 如下：

SELECT COUNT(1) "笔数", TRUNC(SUM(A.JYJE)/10000, 2) "金额/万元"
FROM SKY.JY_RKLS A
WHERE A.dcpzlx_dm = '1'
AND SUBSTR(A.YSKM_DM, 0, 7) = '1010602'
AND A.JYJE > 0
AND A.PZHM LIKE '6%'
AND A.Date >= TO_DATE('2023-03-01', 'YYYY-MM-DD');
