something like this:
SELECT * FROM table1
WHERE ???

Tricky Query Need Help

Aug 29, 2001

I have a feeling it is very easy to do what I want. But I don't know how.
I have 2 queries that return 2 results sets. I'd like to have just 1 query
that returns 1 result set that contains all the data of the 2 results sets.

Example.
Query 1 returns
Item Expected
--------------------
Lion 2
Tiger 2
Bear 2

Query 2 returns
Item Actual
-------------------
Lion 1
Bear 1


What I want is 1 query that will combine the results
Item Expected Actual
-------------------------------
Lion 2 1
Tiger 2 0
Bear 2 1


I tried using a unions between the 2 queries but that doesn't work.
I am pulling my hair out. I have been struggling with this for several
days now. Any help would be greatly appreciated.

Thanks
Josh

Tricky Query

Nov 16, 2005

Hi,

I need to return a number of records at specifik days, i do it with this query;

SELECT LEFT(CONVERT(varchar, CLF_LogGenerationTime, 120), 10) AS Days, COUNT(LEFT(CONVERT(varchar, CLF_LogGenerationTime, 120), 10))
AS Numbers_total, COUNT(LEFT(CONVERT(varchar, CLF_LogGenerationTime, 120), 10)) AS Numbers_In
FROM tb_SecurityLog
WHERE (CONVERT(varchar, CLF_LogGenerationTime, 120) BETWEEN @fyear + @fmonth + @fday AND @tyear + @tmonth + @tday) AND
(SL_PolicyName LIKE N'%')
GROUP BY LEFT(CONVERT(varchar, CLF_LogGenerationTime, 120), 10)
ORDER BY LEFT(CONVERT(varchar, CLF_LogGenerationTime, 120), 10)

i also need to have a criteria at that second COUNT and if the criteria is not met that row should not be counted, is this possible at all?

Tricky Query

Feb 22, 2007

I have a data table like this:

MachineIDProductSales
-------------------------------
1Magazine$20.00
1Drink$30.00
2Drink$30.00
3Magazine$30.00
3Drink$40.00
4Magazine$30.00
5Food$40.00
5Drink$30.00
6Drink$40.00

One of the reports the user needs to see looks like this:

ProductNumber of MachinesTotal Sales
Magazine/Drink2$120.00
Drink2$70.00
Magazine1$30.00
Food/Drink1$70.00

To clarify:

There are two magazine/drink machines (ID 1 and 3)
There are two drink only machines (ID 2 and 6)
There is one magazine only machine (ID 4)
There is one food and drink machine (ID 5)

How do I do this query?

Ideally, I wouldn't limit the number of products in a given machine, but I can do so if necessary.

I'm using SQL Server 2000 so I can't use the newer PIVOT/UNPIVOT functions in SQL Server 2005.

Here is some setup T-SQL code:


CREATE TABLE SalesData
(
MachineIDINTEGER,
ProductNameVARCHAR(50),
SalesMONEY
)

INSERT INTO SalesData (MachineID, ProductName, Sales) VALUES (1, 'Magazine', 20)
INSERT INTO SalesData (MachineID, ProductName, Sales) VALUES (1, 'Drink', 30)
INSERT INTO SalesData (MachineID, ProductName, Sales) VALUES (2, 'Drink', 30)
INSERT INTO SalesData (MachineID, ProductName, Sales) VALUES (3, 'Magazine', 30)
INSERT INTO SalesData (MachineID, ProductName, Sales) VALUES (3, 'Drink', 40)
INSERT INTO SalesData (MachineID, ProductName, Sales) VALUES (4, 'Magazine', 30)
INSERT INTO SalesData (MachineID, ProductName, Sales) VALUES (5, 'Food', 40)
INSERT INTO SalesData (MachineID, ProductName, Sales) VALUES (5, 'Drink', 30)
INSERT INTO SalesData (MachineID, ProductName, Sales) VALUES (6, 'Drink', 40)


Of course, this is a much simplified version of the real business problem I'm facing. Any help is greatly appreciated. Thanks!

A Tricky Query

Aug 10, 2007

Hello

I have a table: myTable(#Product_ID, #Month, Value), where Product_ID and Month are the PK columns. I would like to retrieve all the rows from Month 10 to Month 12, if-and-only-if all the Values are the same (and not NULL).

Example:

(Cod01, 10, 456), (Cod01, 11, 456), (Cod01, 12, 456) <--- Would pass
(Cod02, 10, 1234), (Cod02, 11, 1234), (Cod02, 12, 1234) <--- Would pass

(Cod03, 10, 345), (Cod03, 11, 1677), (Cod03, 12, 981) <--- Would not pass


How can I accomplish that?

Thanks a lot.

Tricky TOP TEN Query

Aug 3, 2006

I'm self-taught at SQL, so this may be an easy one for others, but I can't even figure out how to search for an answer.

I need to put together a query as a datasource for a chart showing the firm's top ten clients by revenue AND the top ten clients by hours worked. It's easy to do either query separately, but the problem comes in when the two are combined. Then top ten by revenue doesn't always include all the top ten by hours clients, and vice versa [at the moment, I'm running a top twenty for each, then hand-compiling the top ten in Excel--oy!].

How can I write a query that will guarantee to include the top ten of both revenue and hours lists?

Thanks,

Tricky SQL Query ??

Mar 26, 2008

Hi All,

We've a table which has about 1.5 mil records.
The table has info like AccountNum FName LName, Flag, Address etc.
There are duplicate Account Numbers.

What we're trying to accomplish is:

If I query the table as in the following,
SELECT AccountNum, Flag, COUNT(*) AS CountStar FROM Table1
GROUP BY AccountNum, Flag
HAVING COUNT(*) > 1

I'll get something like this:

AccountNum Flag CountStar
1234567 Y 2
9876543 Y 4
9184382 Y 3
7439831 Y 5
6958373 Y 4
....... . .
....... . . etc..

First, I want to display the result as in the following:

AccountNum Flag
1234567 Y (along with other columns)
1234567 Y
9876543 Y
9876543 Y
9876543 Y
9876543 Y
9184382 Y
9184382 Y
9184382 Y
....... .
....... . etc...

Is it possible?

Once I've the result in the above format, the next step in plan is to update the flag with 'N' leaving the first occurrence flag as 'Y' but all others as 'N' for a particular AccountNum.
Once I do this, the result should look like the following:


AccountNum Flag
1234567 Y (along with other columns)
1234567 N
9876543 Y
9876543 N
9876543 N
9876543 N
9184382 Y
9184382 N
9184382 N
....... .
....... . etc...

Can anybody suggest any ideas how to accomplish this?

Thanks much,
Siva.

Tricky Grouping Query

Jul 20, 2005

I'm having much difficulty figuring out how to write the followingquery. Please help!I have this table:EventEventId int Primary KeyPatientId intSeverityLevel intWhat I want returned in my query is a list of all (distinct)PatientIds appearing in Event, with the *most severe* EventId returnedfor each Patient. The higher the value of SeverityLevel, the moresevere that Event is considered to be.The problem I am having is that I can't figure out how to (a) group byPatientId, AND (b) return the EventId of the highest-severity Eventfor *each* PatientId (Order By SeverityLevel Desc).So if my table contained:EventId PatientId SeverityLevel------- --------- -------------1 1 02 1 13 1 54 2 55 2 2I would want my result set to be:PatientId EventId--------- -------1 32 4since events 3 and 4 are the most severe events for patients 1 and 2,respectively.Any help would be greatly appreciated. This seems to be something thatcould be handled easily with a FIRST() aggregate operator (as in MSAccess) but this is apparently lacking in SQL Server. Also note theremay be multiple Events with a given PatientId and SeverityLevel, inthat case I'd want only one of the EventIds (the Max() one).Many thanks,Joel ThorntonDeveloper, Total Living Choices<joelt@tlchoices.com>(206) 709-2801 x24

Tricky Group By Order By Query

Jul 23, 2005

Hello, I'm trying to find the most optimal way to perform a trickyquery. I'm hoping this is some sort of standard problem that has beensolved before, but I'm not finding anything too useful so far. I havea solution that works (using subqueries), but is pretty slow.Assume I have two tables:[Item]ItemID int (Primary Key)ItemSourceID intItemUniversalKey uniqueidentifierPrice int[Source]ItemSourceIDPriorityI'm looking for a set of ItemIDs that match a query to the Price(something like Price < 30), with a unique ItemUniversalKey, taking thefirst item with each key according to Source.Priority.So, given Item rows like this:1 2 [key_one] 152 2 [key_two] 253 1 [key_one] 15and Source rows like this:1 12 2I want results like this:2 2 [key_two] 253 1 [key_one] 15Row 1 in Item would be eliminated because it shares an ItemUniversalKeywith row 3, and row 3's Source.Priority is lower than row 1.Help!?

Tricky Case Sensitive Query On SQL7

Jul 23, 2005

I have a SQL7 database that was installed as case-insensitive./* Sort Order = 52, Case-insensitive dictionary sort order. */This database contains a table that has a varchar column which containsdata such as:'JUDICIARY; EDUCATION; Subcommittee on Justice and Judiciary''Subcommittee on Justice and Judiciary; TRANSPORTATION''Subcommittee on Cities; JUDICIARY; TRANSPORTATION'I want to write a SELECT statement that gives me only those rows (1stand 3rd) that have JUDICIARY (not Judiciary) in the varchar column.This is SQL7 so I can't use COLLATE.I triedSELECT mycolFROM mytableWHERE mycol LIKE '%JUDICIARY%'AND CAST(SUBSTRING(mycol ,PATINDEX('%JUDICIARY%',mycol),LEN('JUDICIARY')) AS VARBINARY) = CAST('JUDICIARY' AS VARBINARY)But this leaves out the row with JUDICIARY and Judiciary in it (onlyreturns 3rd row).Any suggestions?

Tricky Query For Joing Master-detail Tables

Feb 28, 2002

I need to write a sql query which is a master-detail query. Here's the example structure of tables:

Master table:
ColID as longint, ColA as int, ColB as int, ColPartID as longint, ColPartName as longint

Child table -- Wheel:
ColID as longint, ColA as int, ColB as int
Child table -- Door:
ColID as longint, ColA as int, ColB as int
Child table -- Window:
ColID as longint, ColA as int, ColB as int
..... etc

From the master table, it needs to join with its child in order to get the detailed information. However, there're more than one child table for it to join. In other words, the query has to choose the correct child table to join for each row selectively. The use of correct child depends on one of the columns in its master table (ColPartName).

My question is: Does it worth of me keep finding a solution for this query or should I abandon this? I really need some advice, please.

Many thanks,
Leonard

Tricky Query, Get Inventory Count By Date Range

Mar 8, 2008

Hi,

My tables:

Product
- productID
- name
- price

Inventory
- productID
- stockCount
- timestamp

So each day the Inventory table has a new row for each productID with its stock count.

How can I create a report for the total products sold from one day to another? Or from what a dateStart from a dateEnd (i.e. a range)

Example:

ProductID StockCount TimeStamp
1 10 2008/03/07
1 7 2008/03/08

So you can see that 3 products were sold in the last day.

What i want to do is sort out Min(r.Resultat) where serier is mor than 3, Not WHERE (r.Resultat) >3. More like in Access "Min(IIf(r.serier=4,r.resultat,Null)) AS [Sämsta]" But that i cant do in SQL

Have also tryed with "WHERE (SELECT MIN(r.Serier) FROM Resultat
Resultat r INNER JOIN

Get lowest result same on all players.

Help With Tricky T-SQL

Hello allI've got this tricky situation that I would like to solve in SQL, butdon't know how to do. This is the table:Id = 3, VId = 2, Time1 = 10:00, Time2 = 14:00Id = 4, VId = 2, Time1 = 16:00, Time2 = 17:00Id = 5, VId = 2, Time1 = 18:00, Time2 = 19:00Id = 6, VId = 2, Time1 = 20:00, Time2 = 21:00Id = 7, VId = 3, Time1 = 11:00, Time2 = 13:00Id = 8, VId = 3, Time1 = 15:00, Time2 = 16:00Id = 9, VId = 3, Time1 = 18:00, Time2 = 20:00GetRows @Time='15:30' will return row with Id=4GetRows @Time='16:30' will return row with Id=4 and row=9Logic behind this:Return row n where Time2 of Id=(n-1) < @Time < Time 1 of Id=(n) and sameVId.Ie. if @Time = '15:30' then Time2 of Id = 3 is lower than @Time, andTime1 of Id = 4 is higher than @Time => return row with Id = 4.This got a bit messy but if someone could decipher this and possiblygive an answer I'd be very glad.regardsJohnny

Here's A Tricky One

Jan 28, 2008

I have an integer in the database that was saved in reverse byte order (BigEndian). Due to some backward compatibility issues (long story) I can't just convert the number to the normal format and save it that way in the database.
Instead, when I read the number in my program, I just reverse its bytes and display the proper value, and translate the number back when it has to be saved back to the database.

Now, the problem is that there are some views that pull this numbers directly from the database and display it.

My question is: can this number be converted from BigEndian to LittleEndian similarly to how I do in my program using T-SQL?

Thanks.

Need To Do Some Tricky SQL Sorting

Dec 13, 2007

This is more of a SQL question than a .NET question, but if you could indulge me, I'd appreciate it.
I have a table that has 2 columns of particular interest for the purposes of this question.  One is a foreign key to another table (int), the other is a name (varchar(50).  I want to sort the results set in a specific way.  I want to sort it in such a way that all entries that have the foreign key = 0 come first (sorted ASC by name) then I'd like all the other results with foreign key column > 0 to be sorted ASC by name.  I was trying to be cute and tried an order by statement like this:  "ORDER BY (foreignKey > 0), name" but it's a syntax error (as I initially thought it might be).  I know I could probably do a stored procedure that will create a temporary table and I could insert a new column to help put these in order, and I also know I could put all the results into an array, then sort the array in code, but I was just wondering if there was a simpler, slicker way (tricky SQL query perhaps).

Tricky SQL Statement (for Me)

Oct 6, 2004

I have a stored procedure called TC3_GetAllJobOrders which takes 8 parameters as filter values and dynamically builds a statement to filter the data. If you pass in null values for the filters, then the data is not filtered.

I want to write another SP called TC3_GetNewestJobOrders which takes 9 parameters. The first 8 parameters are the same as TC3_GetAllJobOrders and the 9th parameter is numRecs which defines the number of records to return. The procedure should call TC3_GetAllJobOrders, sort the data by date and then return the top numRecs. However, I can't figure out the best way to write this stored procedure because it references another one.

I am trying to stay away from dynamic SQL if at all possible. But I am thinking I will have to use dynamic SQL because I don't think the number of records to be returned (as defined using the TOP keyword) can be parameterized. However, I was trying to write a dynamic SQL statement so that the end statement looked something like:

SELECT TOP 10 * FROM ( EXECUTE TC3_GetAllJobOrders ... ) ORDER BY createdOn DESC

However, I guess having the EXECUTE in parens like that is no good and SQL Server doesn't like it. What is the best/correct way to do it?

Tricky Delete

Mar 7, 2000

I have 2 tables which are related to each other, each having a Foreign Keys of the other table . When I delete company table, it gives me an error that I'm violating a FK constraint of the table owner. When I try to delete employee, it gives the same error.

CREATE TABLE OWNER {
employee_id PK
company_id - this is a FK of COMPANY
}

CREATE TABLE COMPANY{
company_id PK
owner_id - this is a FK of OWNER
}

Must I drop the constraints before I can delete? I don't want to do that because I don't want so many other tables are dependent on those tables.

Tricky Sql Problem

Hello all,
I'm very new to SQL, but find myself with this problem that i've been working on for a while, but I just can't figure out how to work through it.
I've got a database of appointments for vehicles. This database holds start time, month, day, year, end day month, year... etc.

I want to make a query that allows users to select a begining year, month day etc. and ending month year etc.

so i've got this query (I'm using PHP, so the $...'s are just $_Post variables.

so here's my query:
$query = "SELECT * FROM `appointments` WHERE start_year BETWEEN $start_year AND $end_year AND start_month >= $start_month AND end_month <= $end_month AND start_day >= $start_day ORDER BY start_year, start_month, start_day, start_time ASC";

When I try to run this query, if the start month is january, and the end month is january (regardless of year), it returns nothing (because nothing is between january and january, and it's not factoring in the year change. How can I factor in the year?)


Any input is greatly appreciated, I hope you understand where I'm running into trouble.
Thanks again!

Tricky SELECT

Jul 18, 2007

I have a LastName field which holds this data
LastName
Johnson|Vasques
Adams|Fox|Johnson
Vasques|Smith

Now let’s say I have a SELECT Stored Procedure which takes 1 parameter @LastName.

The @LastName can be something like this: “Fox|Smith�.
I would like to have my SP to return me all of the records where LastName field have any of those names (Fox or Smith).

In this example it will be the last two records: Adams|Fox|Johnson and Vasques|Smith .

Thank you.

Tricky SQL Statement.

Oct 7, 2007

Hi guys,

Im trying to devise a statement with will return a true/false value based on if a field in a related table is null or not.

That is I have two tables: ServiceRepairOrders (Parent Table), LoanPhones (Child Table) related by the field "IMEI_ESN", which is a 15 character string.

When returning a "LoanPhone" record, i need one field "InStore", to return true/false based on if one or more related "CompletionDate" fields in ServiceRepairOrders is null or not.

At the moment I have the following:

SELECT LoanPhones.IMEI_ESN, LoanPhones.BoxNumber, LoanPhones.Make, LoanPhones.Model, [ServiceRepairOrders].[CompletionDate] Is Null AS InStore
FROM LoanPhones INNER JOIN ServiceRepairOrders ON LoanPhones.IMEI_ESN = ServiceRepairOrders.LoanPhoneIMEI_ESN;

But i need to ensure its a "one or more" relationship. That is, if all related service repair orders are complete (i.e. a completion date is supplied - not null), then the IsStore should be "True", otherwise false.

A Tricky Task

Dec 3, 2007

IN sql server 2005, you can rename a db table as sp_tbl1 by right clicking the table in object explorer and rename it to sp_tbl1,

The task is if you want to again change back the name from sp_tbl1 to tbl1 then sql server does not alow you to do that.

Is there any other way using dbcc commands or anything else to get that renamed back??

Thanks,
Kumar
