I know I'm missing something here but I can't figure out what it is. I've got a query joining three tables....accounts, payments, and a table linking the two (there is a M:M relationship).I'm trying to pull a list of all accounts in the account table that have a payment that needs to be resequenced, and also the maximum payment priority if there are any payments that haven't been fully paid. If all payments HAVE been fully paid, I want to return a 0.
It's that last bit of logic that I can't get right. If I include that in the where clause, I get only the accounts that have a payment that hasn't been fully paid. If I take it out, I get all the accounts I get, but I get the highest payment priority whether or not the payment has been fully met.
Here is the query....how do I include the where clause criteria but still include all accounts?
select distinct
bat.acct_id,
isnull(max(isnull(crt.pymt_priority, 0)), 0)[code].....
I have a function or binding grid where i pass the flag for query to be displayed for page load i have below query
if (flag=="pageload){sql= "select "; sql= sql * " from (select top 50 * " from ";
sql= sql+ "(select top 50 * from EMPLOYEE order by NAME )";
sql= sql+ " as T1 order by T1.NAME DESC) as T2 order by NAME ASC ";
} else if flag=="filteration select * from EMPLOYEE
In the above query i get 50 records per page & the next prev navigation works fine but when i filter out the records i cant use the above query to get the filtered records as I need to filter from the whole recordset say I have total 1000 records after filtering i get 500 records after filtration i am not able to navigate across the records correctly...

I can join with a regular SQL table fine but this won't work:
SELECT normalTbl.*, tmp.fld1 FROM normalTbl
LEFT JOIN #Temp tmp ON tmp.joinID = normalTbl.joinID
All tmp.fld1 values are shown as NULL even though fld1 contains valid values and the joinID matches the normalTbl (when I call SELECT * from #Temp). If I do the same exact thing with a regular table, fld1 shows the correct value. What am I doing wrong?
i want to delete data from two table using left outer join..
here is my query:
delete from projects p LEFT OUTER JOIN emp_project empp on p.serial_no=empp.projectid where p.serial_no=7

Incorrect syntax near 'p'.
my stored procedure is always extract some data into temp table such as"select name,address,content into #TEMP1 from table1,table2,table3"
finally, select another table together with #TEMP1 to extract all desire data from one queryselect T.name,T.address,T.content,C.other from #TEMP1 T, otherTable C
where T.ID=C.IDI would like to ask if i want to join one more table T2 into final query with "otherTable left C outer join on C.ID=T2.ID"
I have set up Linq to sql. I now need to fill a formview with a select that does a join across a few tables. Have not been able to find any example or tuts that go beyond the simple select. Any suggestions? Can this even be done?

I'm putting together a way to cull out bad emails from my table.
I have an email field, of course, and a 'fail' field (integer)
Each time I send out an email, I get a bunch of emails back that the email addresses were undeliverable, so I'd like to (manually), enter them all into an array (or whatever), and then run a stored procedure which updates the 'fail' field by 1
I'm looking for both on the SQL side (I have an sProc that does the deed one at a time - just need the logic to do it in a batch like this), and how to do it in the web page.....

i understand here that setting the rowcount variable to 1 will force the select statements to return only one record, do all above select statements return one record only?
