I am having difficulty selecting data from 2 tables that do no share a primary key value. For instance, I have an actual table, a forecast table, and a GLText table. I may have an actual value but not a forecast value but I need them to appear in the same Query (like the query results shown below). I can get all values to appear in each table but have been unsuccessful in getting all values from both tables.

I have two dropdown list, which is 'names' and 'types' and it's being populated by a dataset. It contains an additional item "-- ALL --" to indicate that all items of a particular field are being shown. I have an SQL select statement to filter the records according to the selected item of the dropdowns. I used a select statement to bind the records to a datagrid with regards to the selected items.
SELECT * FROM table where name = ddlnameselecteditem AND type = ddltypeselecteditem
The problem now is when I select a name from the names dropdownlist and types dropdownlist has a selection of -- ALL --, there would be no return records because there's no such thing as '-- ALL --' record in column 'types' i'm querying. I need to display rows of the selected 'name' while still showing all the 'types'. How could I achieve this? I think I need to avoid the '-- ALL --' item from the dropdownlist.

I thought this would be easy but cannot now find out of to do it. All I want to do is execute an sql query on a table and in addition to the table's columns I want to also select/output a field that is calculated within the query. The table has a column "Owner" and I want to compare this to the UserId to produce a bool column "mine". Effectively doing:Select *, (Owner=@UserId) as mine where.....however, this doesn't work so how can I calculate a column in the select statement?

I have to pull up a list of people by their branch number which could vary, and give a detailed report on there performance using a select queries. I have the select queries but how can i create a script to look similar to this one. Ive got the branch drop downlist already created just need to know how i can go about pulling all the users in this group and doing this select to all of them. someone told me I might need to use cursors to loop thru a select with every person in the list but im not sure how to go about that.
select fldusername from tbluser where fldio='o' and
flduserbranch=@branchid
is going to give me the names of the people i need to query. but how can i run a query on each of them seperate?

Here is the deal. I need to create a Stored Procedure that has 2 SELECT statements. Now in ASP.NET, I know that a DataSet can have multiple tables and the DataAdapter can do just that. I am stuck with a scenario where I need to get a value from the first SELECT statement which will later be used in the second SELECT statement. I am creating a SP that passes one parameter (@AnswerID). Which should give me 2 resultsets. See below SELECT statements.
[Code]....
So how do I get the QuestionID from the first SELECT statement?
Basically I am creating a Questionnaire that has Question Dependacies. So from the above SQL statements I would like to display the Question Title with it's relevant answer options but depending on the previous Answer selected hence the @AnswerID parameter.
The reason why I want to use 2 SELECT statements is because I don't want to have 2 roundtrips to th server. So in my code the DataAdapter should return 2 resultsets and fill the DataSet.
If there is any another solution that can prevent 2 roundtrips to the server, I would most definitely like to know how to do it.

this might be an easy one, but I just can't get it.I am creating a page which will query a table with many columns and most items are not unique. I need to be able to get a list of records that match as many of the (up to 4) search criteria as possible.Example:am user searching for the following items, I enter at least one and up to 4 of the items below in a text box:Name, age, gender, weight (user may or may not fill in all of them).If he just enters "F" for gender, then he will get a list of thousands of females with their name, age, gender and weight.However if he enters "F" for gender and "300" for weight, he will get a much smaller list of returned records.I need to be able to create a sql statement that can perform that search with that functionality.

here is a sql select statement,
Select
ColA = ID
,ColB = Name
,ColC = invtotamt + (SELECT SUM(TableA.camount) FROM TableA WHERE TableA.csucceed = 1 AND TableA.cID = InventoryTotal.invID GROUP BY TableA.cID)
,ColD = ((SELECT SUM(TableA.camount) FROM TableA WHERE TableA.csucceed = 1 AND TableA.cID = InventoryTotal.invID GROUP BY TableA.cID)
,ColE = (SELECT SUM(TableB.camount) FROM TableB WHERE TableB.csucceed = 1 AND TableB.cID = InventoryTotal.invID GROUP BY TableB.cID)
FROM TABLE
it look complicated, and long statement, actually it's easy, it is like: (it's a sample, not a really one)
Select
ColA = ID
,ColB = Name
,ColC = ColD + ColE
,ColD = ColE + ColC
,ColE = ColC + ColD/100
FROM TABLE
