Combining 2 queries in SQL 2008

DavidHa!! — Fri, 04 Mar 2011 15:34:54 +0000

I am having a little trouble combining the following 2 queries into a single nested statement (if indeed it’s possible). Can anyone assist?

Query 1:

SELECT Eff_Date, CoNum, Brandname, COUNT(Brandname) AS CountOfBrandName FROM dbo.Products WHERE (Eff_Date BETWEEN ’1/1/2010′ AND ’12/31/2010′) GROUP BY Eff_Date, CoNum, Brandname, DateApplied

Query 2:

SELECT Eff_Date, CoNum, SUM(CountOfBrandName) AS SUMofBrandNames FROM dbo.Query1 GROUP BY Eff_Date, CoNum ORDER BY Eff_Date

Can anyone assist in combining these 2 queries into a single nested statement? Can it be done without using a temp table?

Hello friends,

On my PC (Windows Xp 2002 SP3) in SQL-Server management studio 2008, the object explorator filter doesn’t work. The funnel symbol is simply greyed. I can’t access to the box bialog filter parameters. Please, anybody has an idea ?

SQL select loop list?

Vinical — Fri, 04 Sep 2009 03:25:18 +0000

Say I want to derive the following: Select ID, F1 from table Union Select ID, F2 from table Union Select ID, F3 from table Union … etc until F10. Is there smart and easy way so that I can just provide a list: F1,F2,F3,…,F10 and somehow be able to have the select statement loop through it? Also, in addition to 2 columns, ID and Fn, I would also like a third column in the result which states the field name F1, F2,…, F3. Thank you so much.

How to automatically update Child Table with Insert Trigger and Table-UDF

Ironryan77 — Fri, 12 Jun 2009 15:14:24 +0000

I have SQL Server 2008 and Visual Studio 2008 and am trying to automatically insert new records into a child table based on new inserts into its parent table.

I know that this should be simple: via an insert trigger. However, the complexity is that the new records into the child table need to be a parsed version of one of the parent table’s fields.

To achieve this, I developed a table function which parses this one field in the parent table.
Originally I had the Foreign Key defined below, but this wasn’t automatically inserting new records into my child table, so I commented it out.

I have tried writing both recursive and non-recursive insert triggers, but I have received errors on almost every attempt. I was able to partly get non-recursive triggers to work…but without the parsing function. I think the trick is that this is a table function.
How should I design this? Some of my pseudo code as follows:

CREATE TABLE ParentTable
(
ParentID INT IDENTITY(1,1) PRIMARY KEY NONCLUSTERED,
strInput VARCHAR(8000) NULL
)

CREATE TABLE ChildTable
(
ChildID INT IDENTITY(1,1) PRIMARY KEY NONCLUSTERED,
ParentID INT,
FullRow VARCHAR(8000)
–I removed the following FK cause it wasn’t automatically inserting new records:
–CONSTRAINT AddParentID FOREIGN KEY ParentID REFERENCES ParentTable(ParentID)
)

Sample output of what I want is:
ParentTable:
ParentID strInput
1 ‘AAA|BB|CCCCCC|D|EE’
2 ‘FFF|R|BC|D|EE’
3 ‘GG|BB|CCHC|D|EE’

ChildTable:
ChildID ParentID strInput
1 1 ‘AAA’
2 1 ‘BB’
3 1 ‘CCCCCC’
4 1 ‘D’
5 1 ‘EE’
6 2 ‘FFF’
7 2 ‘R’
8 2 ‘BC’
9 2 ‘D’
10 2 ‘EE’
…

My table-function removes the “|” delimiter with strInput as its input. How can I achieve the above results?

Thanks!
