Hi, good morning,

I have problem with stored procedure.

In SQL stored procedure I make 3 temp table like #table1,#table2,#table3 and all three table have 2 column like #table1(total1,Code),#table2(total2,Code) ,#table3(total3,Code).
In these 3 table code is data is same but total field have different value,#table1 and #table2 have data every time but #table3 have almost empty record but some case #table3 also have record.

My select Query is given below.

SQL

select t1.total1,t2.total2,t3.total3
from #table1 t1 
inner join #table2 t2 on t1.Code=t2.Code
inner join #table3 t3 on t2.code=t3.Code

It's not displaying the t1.total1,t2.total2,t3.total3 value if #table3 is empty record but if #table3 not empty then its show the value.

So please help me how I solve this issue

thanks

Solution 1

You can try using outer joins instead of inner joins.
This will help you get data even when table 3 is empty.

Solution 3

Use following Query (this tested with dummy database on my end)

SQL

SELECT t1.total1,t2.total2,t3.total3 FROM #table1 t1
INNER JOIN  #table2 t2 ON t1.code = t2.code
LEFT OUTER JOIN  #table3 t3 ON t1.code = t3.code

Thanks,

Solution 2

Try making the second join a RIGHT OUTER JOIN: See http://en.wikipedia.org/wiki/Join_(SQL)[^] - from how I read your question, that may solve the problem.

Case 1 - #table1 contains all codes

SQL

select t1.code,t1.total1,t2.total2,t3.total3
from #table1 t1
left join #table2 t2 on t2.Code=t1.Code
left join #table3 t3 on t3.code=t1.Code

Case 2 - none of the tables contains all codes

SQL

select c.code,t1.total1,t2.total2,t3.total3
from   (
       -- all codes
       select code from #table1
       union
       select code from #table2
       union
       select code from #table3
       ) c
left join #table1 t2 on t1.Code=c.Code
left join #table2 t2 on t2.Code=c.Code
left join #table3 t3 on t3.code=c.Code
