我有一个变量名称,说"WARD_VS_VITAL_SIGNS",我想将其转换为Pascal案例格式:"WardVsVitalSigns"

WARD_VS_VITAL_SIGNS -> WardVsVitalSigns

我怎样才能进行这种转换？

我想从单个select语句中获取所有选定的列而不执行执行.查询可能使用join或union,那么查询可能不只是一个表,所以我不能简单地使用该语句

select column_name, data_type
from user_tab_cols
where table_name = 'my_table_name'

得到结果.

例如

输入:

select db1.*
  from (select dept_code,
               vital_signs,
               units,
               log_time
          from table1
         where dept_code = '111'
        union
        select 'hl06' as dept_code,
               vital_signs,
               units,
               log_time
          from table2
         where isdefault = 1
           and vital_signs not in
               (select vital_signs
                  from Ward_Vs_Vital_Signs
                 where dept_code = '111')) db1,
       table3 db2
 where db1.vital_signs = db2.vital_signs(+)
 order by db2.serial_no 

输出:

column_name  | data_type
-------------------------
dept_code    | VARCHAR 
vital_signs  | NUMBER
units        | VARCHAR
log_time     | DATE …
