Try
SELECT * FROM t1
WHERE prod_code IN (SELECT prod_code FROM productslist)
And
SELECT * FROM t1
WHERE prod_code IN (SELECT prod_code FROM productslist WHERE bin_location =
"XH256")
- Can you ensure that each of the above (in turn) are entered as one line
of SQL.
- What's the exact error you are being returned when you execute the SQL
- Could you confirm the version of SQL that you're running.
To test this I have created two tables on my computer ("tasks" and
"day_types"). "tasks" contains two columns ('task' and 'task_day') and
"days" contains two columns ('day_name' and 'day_type'). The data is simple:
"TASKS"
'task_day' 'task'
Mon Work Hard
Tue Work Hard
Wed Work Hard
Thur Work Hard
Fri Surf Internet
Sat Football
Sun Church
"DAY_TYPES"
'day' 'day_type'
Mon Weekday
Tue Weekday
Wed Weekday
Thur Weekday
Fri Weekday
Sat Weekend
Sun Weekend
Two queries:
(1) select * from where task_day in (select day from day_types where
day_type = "Weekday")
Mon Work Hard
Tue Work Hard
Wed Work Hard
Thur Work Hard
Fri Surf Internet
(2) select * from where task_day not in (select day from day_types where
day_type = "Weekday")
Sat Football
Sun Church
Not a lot of help, but it does prove that the principal works.
Just thinking about this, perhaps you could go about it another way....
SELECT *
FROM productslist PL
LEFT JOIN table1 T1 on T1.prod_code = PL.prod_code
LEFT JOIN table2 T2 on T2.prod_code = PL.prod_code
WHERE PL.bin_location = "XH256"
