illegal reference to correlation name

[Former Member]

I get the error "Illegal reference to correlation name 'edef'", but I don't know why or how to fix it. Here is my SQL statement. Please help!

/*
gets employee clock in/clock out times and total hours
*/

select
    edef.emp_seq,
    edef.obj_num,
    edef.payroll_id,
    edef.last_name,
    edef.first_name,

    dtl.clk_in_date_tm,
    dtl.clk_out_date_tm,
    dtl.reg_hrs,

    ot.order_type_seq,
    otdef.name
from
    MICROS.emp_def edef,

    MICROS.time_card_dtl as dtl

left join 
(
    select
        MICROS.shift_emp_ot_ttl.emp_seq,
        MICROS.shift_emp_ot_ttl.order_type_seq
    from
        MICROS.shift_emp_ot_ttl
)ot on ot.emp_seq = edef.emp_seq
left join
(
    select
        micros.order_type_def.order_type_seq,
        micros.order_type_def.name
    from
        micros.order_type_def
)otdef on otdef.order_type_seq = ot.order_type_seq
where
    edef.emp_seq = dtl.emp_seq
    and 
    dtl.clk_in_date_tm between '2013-05-06 00:07:00' and '2013-05-07 00:04:00'
order by
edef.last_name

I think it might help to know which version and build number you are using?

I did a select @@version and it gives this:

9.0.2.3586

Is that what you need?

I should also mention that I don't know Sybase very well. I mainly use MySQL.

Perhaps the joins need some swapping. Specifically, in the order it is written you have

... edef, ... dtl left join (...) ot on ot.emp_seq = edef.emp_seq

The operands (dtl and ot) for the left join do not match the join condition correlations (ot and edef). Swapping the order of edef and dtl in the query may allow the query to execute without error:

select
    edef.emp_seq,
    edef.obj_num,
    edef.payroll_id,
    edef.last_name,
    edef.first_name,

    dtl.clk_in_date_tm,
    dtl.clk_out_date_tm,
    dtl.reg_hrs,

    ot.order_type_seq,
    otdef.name
from
    MICROS.time_card_dtl as dtl,

    MICROS.emp_def edef -- switch position of dtl and edef

left join 
(
    select
        MICROS.shift_emp_ot_ttl.emp_seq,
        MICROS.shift_emp_ot_ttl.order_type_seq
    from
        MICROS.shift_emp_ot_ttl
)ot on ot.emp_seq = edef.emp_seq
left join
(
    select
        micros.order_type_def.order_type_seq,
        micros.order_type_def.name
    from
        micros.order_type_def
)otdef on otdef.order_type_seq = ot.order_type_seq
where
    edef.emp_seq = dtl.emp_seq
    and 
    dtl.clk_in_date_tm between '2013-05-06 00:07:00' and '2013-05-07 00:04:00'
order by
edef.last_name

Wow, it looks like that worked as well! So we have at least 2 ways to write this. Thank you!
