Question

If I run the two statements in batch will they return one table to two to my sqlcommand object with the data merged. What I am trying to do is optimize a search by searching twice, the first time on one set of data and then a second on another. They have the same fields and I’d like to have all the records from both tables show and be added to each other. I need this so that I can sort the data between both sets of data but short of writing a stored procedure I can’t think of a way of doing this.

Eg. Table 1 has columns A and B, Table 2 has these same columns but different data source. I then wan to merge them so that if a only exists in one column it is added to the result set and if both exist it eh tables the column B will be summed between the two.

Please note that this is not the same as a full outer join operation as that does not merge the data.

[EDIT]

Here’s what the code looks like:

Select * From  (Select ID,COUNT(*) AS Count From [Table1]) as T1      full outer join  (Select ID,COUNT(*) AS Count From [Table2]) as T2      on t1.ID = T2.ID

Possibly:

select table1.a, table1.b from table1 where table1.a not in (select a from table2) union all select table1.a, table1.b+table2.b as b from table1 inner join table2 on table1.a = table2.a 

edit: perhaps you would benefit from unioning the tables before counting. e.g.

select id, count() as count from (select id from table1  union all  select id from table2)
