案例不适用于sql

Question

select  employee_size_range_id 
from  tbl_employee_size_range 
where employee_range_values = '1 to 10'

以防：

SELECT employee_size_range_id,
       employee_range_values,
       CASE WHEN employee_range_values = '1 to 10' THEN 'employee_size_range_id'
FROM tbl_employee_size_range

Answer 1

 SELECT employee_size_range_id,employee_range_values, 
    CASE WHEN (RTRIM(LTRIM(employee_range_values)) = '1 to 10' ) 
    THEN 'employee_size_range_id' END 
 FROM tbl_employee_size_range.employee_range_values

Answer 2

您在案件陈述中错过了END

Answer 3

试试这个：

SELECT employee_size_range_id,
   employee_range_values,
   CASE WHEN employee_range_values = '1 to 10' THEN employee_size_range_id END AS X
FROM tbl_employee_size_range.employee_range_values

Answer 4

SELECT employee_size_range_id，        employee_range_values，        如果employee_range_values =＆＃39; 1到10＆＃39;那么＆＃39; employee_size_range_id＆＃39;结束 FROM tbl_employee_size_range
