sql - 在主选择和子选择中添加引用另一个表的查询

Question

我有一个用于显示目标和完成时间的表，所有信息都来自一个表“job”-但是我现在想添加更多 SQL 以提供来自另一个表“job_type”的一些信息，但是每当我不断收到错误消息时说“SQLSTATE = S0022 [Oracle][ODBC][Ora]ORA-00904：“JOB_TYPE”。“JOB_TYPE_CODE”：标识符无效。

我拥有的代码（没有我想要添加的代码）

select 
job_number, priority_code, job_entry_date, clock_start, 
site_code,
TO_CHAR(job_entry_date, 'Dy') as DAY_LOGGED,
TO_CHAR(actual_start_date, 'IW') as WEEK_ON_SITE,
actual_start_date,
actual_comp_date,

-- kpi tracker
CASE
WHEN actual_start_date is null AND current_date < target_time THEN 'Not arrived on site yet'
WHEN actual_start_date is null AND current_date > target_time THEN 'FAIL (2)'
when actual_start_date <= target_time then 'Pass'
when actual_start_date > target_time then 'FAIL'
ELSE 'Overdue' END as Arrived_on_time_check,

-- start of correct target time SQL
case
when to_char(target_time, 'Dy', 'NLS_DATE_LANGUAGE=ENGLISH') = 'Fri'
and floor((target_time - trunc(target_time)) * 24) >= 17
then target_time + 2 + 63/24
when floor((target_time - trunc(target_time)) * 24) >= 17
then target_time + 15/24
else target_time
end as target_time

from 
        (
        select job_number, priority_code, job_entry_date, clock_start, site_code, actual_start_date, actual_comp_date, 
        CASE 
        WHEN PRIORITY_CODE IN ('GC01','GC02','GC03','GC04','GC05','GC06','GC07') 
        THEN
        clock_start + case priority_code 
        when 'GC01' then 1 
        when 'GC02' then 2 
        when 'GC03' then 0.5
        when 'GC04' then 1 
        when 'GC05' then 2 
        when 'GC06' then 4
        when 'GC07' then 24
        end / 24 
        ELSE TARGET_COMP_DATE END as target_time

        from                
                    (
                    select job_number, priority_code, job_entry_date, target_comp_date, site_code, actual_start_date, actual_comp_date,
                    case
                    when to_char(job_entry_date, 'Dy', 'NLS_DATE_LANGUAGE=ENGLISH') = 'Fri'
                    and floor((job_entry_date - trunc(job_entry_date)) * 24) >= 17
                    then trunc(job_entry_date) + 80/24
                    when to_char(job_entry_date, 'Dy', 'NLS_DATE_LANGUAGE=ENGLISH') = 'Sat'
                    then trunc(job_entry_date) + 56/24
                    when to_char(job_entry_date, 'Dy', 'NLS_DATE_LANGUAGE=ENGLISH') = 'Sun'
                    or floor((job_entry_date - trunc(job_entry_date)) * 24) >= 17
                    then trunc(job_entry_date) + 32/24
                    when floor((job_entry_date - trunc(job_entry_date)) * 24) < 8
                    then trunc(job_entry_date) + 8/24
                    else job_entry_date
                    end as clock_start
                    from job
                    )

        )




where
priority_code in ('GC01','GC02','GC03','GC04','GC05','GC06','GC07')

我要添加的代码是：

-- JOB KPI ATTRIBUTE LOOK UP IN GJOB TABLE
(SELECT attribute_value.attrib_value_name FROM attribute_value WHERE 
attribute_value.attrib_type_code = 'GJOB' 
AND attribute_value.attrib_value_code = job_type.job_type_code) as JOB_KPI,

-- JOB KPI PENALTY POINTS LOOK UP IN GJOB TABLE
(SELECT attribute_value.attrib_value_nom FROM attribute_value WHERE 
attribute_value.attrib_type_code = 'GJOB' 
AND attribute_value.attrib_value_code = job_type.job_type_code) as KPI_POINTS,

如何将上述代码添加到现有代码中而不会出现错误消息指出它是无效标识符？
