Query Logic
Jul 28, 2005
I have 2 tables:
First table: empID,PlanID,groupID
Second: PlanID,groupID,EffectiveDate,TerminationDate,DeadlineDate
I need to show only employee with in spesific group who is not
enroll for the current month until deadline passed.
Example:
empID PlanIDgroupID
11012
PlanIDGroupIDEffectiveDate TerminationdateDeadlineDate
101208/01/200508/31/200508/15/2005
111209/01/200509/31/200509/15/2005
91208/01/200508/31/200508/15/2005
If I run it today I should not get any results back. If I run in
on 8/15/2005 I should get back data with palnID11.

I have some table data and know how I want the results but I'm just having a bit of trouble in constructing the SQL logic to obtain the desired results. There's a site where visitors are able to select from a list of parts, and it will return a set of model/products that they can produce with the selected parts. Here's the data ...
tblModel tblPart
ModelId ModelName PartId PartName
---------------------- ----------------------
1 Alpha 1 CHOO1 Stem
2 Bravo 2 BH034 Rod
3 Bravo Pro 3 HRE Seat
tblModelPart
ModelPartId ModelId PartId
---------------------------------
1 1 1
2 2 1
3 2 3
4 3 1
5 3 2
6 3 3
... and here's the logic that I'm trying to implement, assume that the user selects from a form, parts with the PartId 1 and 3 ...
1. Return all models that contain only the parts selected.
ModelId ModelName
---------------------
2 Bravo
2. Return all models that contain the parts selected, and may contain other parts.
ModelId ModelName
---------------------
2 Bravo
3 Bravo Pro
... so do you have any idea on how the SQL would look for either of these queries?
Thanks in advance,
Goran

I have two tables X,Y
X
empno....Sal.....Tax.....Returns...name
1.....4500....1050.... 750.......robert
2.....5750.....1560....900.......john
3.....4000.....900.....600.......keen
4.....6100....1200.....1000......stauton
Y
empno....Sal.....Tax.....Returns...name
1.....4500....1000.... 000.......robert
2.....5750.....1200....900.......john
3.....4000.....900.....600.......keen
4.....6100....1000.....1000.......stauton
If you see the above tables I have data mismatch in X and Y tables for the same empno.
I need to write a query which shows emp no and columns(name of col) where the data mismatch has occured.
I came up with a query which I have to write for every individual column to get the mismatch.
Since there 120 columns it is pretty hard task..i m looking for a logic where I can write a query which shows mismatched data in columns.
Expected Output
table z
col1..col2
1......tax
3......tax
Appreciate your help.

Hi, sorry for a newbie question but I was wondering if the following is possible:
I have to select some information from a table which I have already created a query for. This information then has to be inserted into a new table but needs another column (not the promary key) with another unique custom identifer for each record in the format EX01 which is incremented by 1 for each record. I was wondering how is it possible to do this?
My approach was to create a view and then insert the values form the view into the new table but I still have no idea how to do the unique identifer. Was the first part of my approach correct or have been wrong from the start?

I have a little system of 3 tables Job, employees and times. This times table has the fields times_id, employee_id and job_idI'm trying to have a query that pull of employees that don't have a certain job_id yet. I'm going to put this data in a table so the user knows they are available for that job. The code i have isn't working, and i'm not sure why.SELECT DISTINCT times.employee_id, employee.employee_nameFROM employee INNER JOIN times ON employee.employee_id = times.employee_id WHERE (times.job_id <> @job_id) Thanks in advance for any help. I'm sure I missing someting silly, or maybe i need to have a stored procedure involved?... Thanks!

Hi All
I have a sqlserver database with product, catagory and sub catagory format. Before I describe my problem, let me share whats I have in db. Their are two types of sinaros, either the products are directly assigned to a catagory or a product is placed in subcatagory that is in turn have a catagory. I use the following table struct for both of the scenarios:
Product>>subcat bridge>>subcatagory
Product>>catbridge>>catagory
Here are the queries to get them:
1. If product assinged direct in catagory then
select product.pid, product.Prd_heading,product.[Description], product.Brand, product.img from product,cat_bridge,category where product.id=cat_bridge.pid and cat_bridge.catid=category.catid;
2. If product assinged to sub cat then
select product.pid, product.Prd_heading,product.[Description], product.Brand, product.img from product,subcat_bridge,subcategory where product.pid=subcat_bridge.pid and subcat_bridge.subcatid=subcategory.subcatid and subcategory.catid=category.catid;
Now the problem is, I want to use a single query to download all the products to a CSV format and I need to combine both of the queries with a single one, probably with if else logic, but I am not getting it, I mean how to acheive. Can anyone help me sort this out?
Thanks in Advance
Regards
Mykhan

I am dealing with two tables and I am trying to take one column from a table and match the records with another table and append the data of that column.
I used an update query that looks like this:
UPDATE Acct_table Set Acct_table.Score =
(Select Score_tbl.Score from Score_tbl
Where Acct_table.Acctnb = Score_tbl.Acctnb
This process has been running for over an hour and a half and is building a large log file. I am curious to know if there is a better command that I can use in order to join the tables and then just drop the column from one to the other. Both tables are indexed on Acctnb.
Any insight would truly help.
Thanks!

I'd like to make a logic statement, that would take as arguments result of the sql select query. In more details: I would like to create a local Bool variable that would be false if some value is NULL in the table (or select query).Query example:select taskID from Users where Login=@usernameWhich classes/methods should i use to solve this problem? I use SqlDataSource to get access to database and i think i should use something like SqlDataSource.UpdateCommand and SqlDataSource.UpdateParameters but dont know how to build from this a logic statement.Thanks in advance

Hello,
I have a requirement to select millions of rows from table and need do some parsing each row. I have identity column on each table.
Here is the query logic I'm following.
Logic A:Uisng While loop processing data row by row

Here is the perormance on the above ran against .5 millions rows of data.
Logic A: Logic B:
CPU usage 564254 464511
Duration 18 15
The above result after completion of the data
The below is from query analyser
Estimated query Cost 21% 79%
Can we trust Estimated query cost? and Which logic you will choose use?.

I have a perl program that is looping through a hash of a hash. I need to Update any existing records but also insert any new records in the table using collected data in the hash.
Life would be very simple if it was possible to use a Where Clause in an Insert statement but not does not work.
Here is some example code from my program:
sub Test{
foreach my $table(keys %$HoH){
foreach my $field(keys %{$HoH->{$table}}){
if($table eq "CPU"){
my $CPUstatement = "INSERT INTO CPU(CPUNumber, Name, MaxClockSpeed, SystemNetName)
Values ('$field',
'$HoH->{CPU}{$field}{Name}',
'$HoH->{CPU}{$field}{MaxClockSpeed}' ,
'$HoH->{Host}{SystemNetName}')";
print "$CPUstatement";
if ($db->Sql($CPUstatement))
{
print "Error on SQL Statement";
Win32::ODBC::DumpError();
}
else
{
print "successful";
}
}
}
}
}

have a SQL2K/VB.NET05 -based website that uses a complex search query, whose results will contain additional logic to be evaluated. There are thousands of records and growing, so it is not feasible to code this within the program...it must be evaluated inline or after the query, and it is also not feasible to set up additional fields and tables to handle the logic.
For a very general example: In the .NET code, the following variables are recognized:
sex="M"
Paid=4350.00
Outstanding=28000.50
One of the query result fields will contain the additional logic to evaluate and another will tell the type of expression..
EVAL EXPR
BOOL Sex='F' and Paid/Outstanding < 27.50
BOOL Sex='M' and Paid/Outstanding < 38 or Sex='F'
INT Paid*52.33
In other words..the thousands of records being returned have their own additional logic to evaluate. Is there a way this can be done by importing the variable into SQL server and testing it during the query?
If not, is there a way that I can run the code in the middle of .NET? I know I could run scripted code while in ASP, but ASP.NET is compiled, so I dont know if it can be done there....

I have a below query which have a date filter like "EST_PICK_DATE between '2015-02-01' and '2015-06-01'", where the logic is EST_PICK_DATE should be 3 months from the current month and 1st date of next month. Ex for current month MAY, EST_PICK_DATE shoulc be between '2015-02-01' and '2015-06-01'. I need to write below query dynamically. In below query i have hardcoded the value ("EST_PICK_DATE between '2015-02-01' and '2015-06-01'"), but it should take dynamically. How to achieve this?
I am using this query in SSIS package, So Shall i do in SQL level or we should implement this logic in package? If yes, How?
INSERT INTO STG_Open_Orders (Div_Code, net_price, gross_price) SELECT ord.DIV_CODE AS Div_Code, ord_l.NET_PRICE AS net_price, ord_l.gross_price AS gross_price, FROM ORD ord inner join ORD_L ord_l ONord.ORD_ID=ord_l.ORD_ID WHERE ord_l.EST_PICK_DATE BETWEEN '2015-02-01' AND'2015-06-01'

Can anyone see where my logic may have gone a stray?
A user would be attempting to update a gridview row, I'm storing the amount of an item and the qty they purchased. If the order was for $150 and the grid has two item 1 x $50 and 2 x $50 the order already totals $150, so if the user tries to change the first item to a qty of 2 x $50 the total would be $200 and this would be more than the total payment or $150.
I want to then tell them they cannot do this.
@AP_ID Int,@AI_ID int,@PurchaseAmount money,@PurchaseQTY int,@LastUpdate datetime,@LastUpdateBy nvarchar(50),@Receipt_ID intASdeclare @current_item_total decimal(18,2)declare @new_item_total decimal(18,2)declare @total_payments decimal(18,2)declare @current_purchase table(receipt_id int,purchase_amt money)INSERT INTO @current_purchase SELECT tblPurchase.Receipt_ID,(tblPurchase.PurchaseAmount * tblPurchase.PurchaseQty) as purchase_amtFROM tblPurchase INNER JOIN tblReceipts ON tblPurchase.Receipt_ID = tblReceipts.Receipt_IDWHERE tblReceipts.Receipt_ID=@receipt_id--Get total already saved to recordselect @current_item_total = sum(purchase_amt) from @current_purchase--Get total amount of payment saved to recordselect @total_payments = sum(tblReceipts.AmountPaid) from tblReceipts where tblReceipts.receipt_id=@receipt_id--Get total amount user is trying to save to recordset @new_item_total = (@PurchaseAmount * @PurchaseQTY)--If current total plus new total is greater than total payment, tell user they cannot do this.IF ((@current_item_total + @new_item_total) > @total_payments)BEGINSELECT 'You are attempting to add more than your total payment.'

Trying to bind some data to a datalist for a report.
User selects an Industry from a dropdown list and then I dump all records for that industry. However in order to parse some of the record field values into names (I.E. from a 1 to the actual company name) for some records I have to read TABLE_ONE and for other records I might have to read TABLE_TWO depending on the value of FIELD_ONE.
If FIELD_ONE = "A" then I get the NAME from TABLE_ONE.
If FIELD_ONE = "B" then I get the NAME from TABLE_TWO.
If FIELD_ONE = "C" then I get the NAME from TABLE_THREE.
I'm lost at how to get started on this. I thought about adding IF statements to my query but these won't work because I'm not passing in the value of FIELD_ONE ahead of time - it's part of the query. So I thought maybe I could do a pre-read and store all FIELD_ONE values in an ArrayList and pass these in as parameters, but the stored proc is only being called once - so that won't work.
Any thoughts on how I can do this?

What i'm trying to do is if this column dt.IN_DIV_NO is populated take that value first if it's null than rr.AIQ_R_DIVISION_NO and if that column is null than rr.F_DIVISION_NO.
This is what i came up with, will it evaluate the way i need it to?
case When dt.IN_DIV_NO is not null then dt.IN_DIV_NO else case when rr.AIQ_R_DIVISION_NO is null then rr.F_DIVISION_NO end end as Current_DIV

I have a logic problem,
I am selecting from a table
Select * from TAB_A
where state not in (1,4)
and create_date < '2008-01-01'
and
(
(x != 2 and y != 1 and z != 4) or
(x != 6 and y != 3 and z != 1) or
(x != 8 and y != 0 and z != 9)
)
then for example i am getting results where x,y and z is equal to one
or more of above combinations ?
Now i vaguely remember that using or with a != messes up the logic ?
if so can i use an NOR ? does it exist ?

I am looking for the best approach to update a table's column based on the results of two other different tables. My tables structure is as follows.
Table 1 has columns A and B (tblemployee has location and employeenumber )
Table 2 has columns C and A (tblocation has locationID (identity) and location)
Table 3 has coumns C and B (tblcountry locationID (foreign key) and employeenumber.)
I want to update Table 3 (tblcountry) with the new locationID if and employee changes location or gets miscoded using an SSIS package.
Thanks in advance.

I'm trying to figure out how to track what messages have been read by what users in a message board program we wrote. The users are identified by an ID number and each message has a unique number.
Let's say there are 10000 users and 200,000 messages. What would be the database setup/logic to track every user as to what messages they had read or not read? Maybe I'm missing something but it does not seem to be a trivial task.

Hi there!
Hope somebody got some better insight into this problem than i have. I'm struggling with some db logic.
Overview:
I have a client who is a publisher. They would like to post all their advert-size specs for each magazine to their web site. My first thought was that ill be able to build one table and populate it with the information for each magazine. I was wrong. Each magazine comes in a different size. Thus each magazine will have different advert-sizes as well.
Layout for a magazine will look something like this:
Size Trim Type Bleed
Full Page 280x440 270x430 290x450
Half Page 140x220 130x210 150x230
etc...
Some mags will not have values for Half pages since they dont print half pages and others will not have specs for Bleed.
Because of this - as an easy way out I created a table per magazine. It works but i dont think its very smart.
Break it down!
Ok so what im trying as a solution is to have three tables. The 1st table will hold the magID and Size values (e.g Half Page). The 2nd table will also have the magID and the Trim, Type, Bleed info. The 3rd table holds magID, sizeID, specID and the actual value (140x220).
I thought that this would be better because within these three tables i can store the information for each magazine regardless of their differences. Brilliant!
The Problem.
The problem comes when i have to put it all back together again. I need to represent this data in a table so i can bind it to a datagrid. I have NO idea how to do this. What i THINK i need to have is some temp table created on the fly. The row names for this temp table will come from the 1st table. The column names will come from the 2nd table and the values for each field will come from the 3rd table bound by foreign keys.
I've somewhat managed to do this with INNER JOINS. But it doesn't give the desired result. I need to set row and column NAMES using tables 1 & 2 then populate the columns with table 3, then bind to a datagrid.
Any ideas on how i could manage this?
If you made it tis far through my question then thanks anyways! I hope you can help me out!

okay;
i have a table called tblSlots
tblSlots is a list of Start datetimes and End datetimes.
every day has the same list of 10 slots.
tblSlots:
PKSlotINDEX
datStartTime
datEndTime
then i have a table called tblPersons
tblPersons:
PKPersonINDEX
txtLast
txtFirst
then i have a table called tblSchedule
tblSchedule:
PKScheduleINDEX
fkSlotINDEX
fkPersonINDEX
i want to write a query that takes any one specific person's schedule for an entire specific day, adds an arbitrary number of days to datStartTime, and finally inserts the PKSlotINDEX corresponding to the calcultated StartTime and fkPersonINDEX.
wow complicated isnt it...
the goal is to take the schedule of one day for one person and copy it to another day; i can scrap my current layout if necessary.
thanks!

Arrrgggg, nothing makes any sence any more. I need to write a select statement that will display results based on one of two things...
Zip Code OR City State
By the way this is a Table of addresses with zip codes, I also have a Lat/Long table associated to all the different zip codes that need to be joined.
The Psuedo code is somethinglike this...
SHOW All People WITH Appropreate Longditude and Latitude
Who Live
In @This ZipCode
OR
(In @State AND @City)
-------------------
Table Dealers
-------------------
dlrID - varchar
dlrName - varchar
dlrAddress - varchar
dlrCity - varchar
dlrState - varchar
dlrZip - varchar
dlrCountry - varchar
-------------------
-------------------
Table ZipCodes
-------------------
zipCode
zipCity
zipState
zipCountrty
zipLat
zipLong
...
-------------------
I have achieved this with Joins but the query takes 2+ minutes to execute
What am I doing wrong??? I am sure there is a better approach to this!
Thanks,

[q2] [nvarchar] (100) COLLATE Latin1_General_CI_AS NULL ,

[q4] [nvarchar] (100) COLLATE Latin1_General_CI_AS NULL ,
[q5] [nvarchar] (100) COLLATE Latin1_General_CI_AS NULL ,
[q6] [nvarchar] (100) COLLATE Latin1_General_CI_AS NULL ,
[q7] [nvarchar] (100) COLLATE Latin1_General_CI_AS NULL ,
[q8] [nvarchar] (100) COLLATE Latin1_General_CI_AS NULL ,
[quizdate] [datetime] NULL ,
[ipaddress] [nvarchar] (50) COLLATE Latin1_General_CI_AS NULL ,
[sessionid] [nvarchar] (50) COLLATE Latin1_General_CI_AS NULL ,
[score] [int] NULL
)
The field [q5] has one of three values in it: "Happy", "Unhappy" or "Neither".
I have a list of about 50 session ID's. If a record in [tblQuiz] has a [sessionid] that matches one in this list, then:
if [q5]= 'Happy' then change it to 'Unhappy'
if [q5]= 'Unhappy' then change it to 'Happy'
The only way I can think of is to change all of one matching record type to some other value, then change all the other type, then change all the original type back to the other type. Which doesn't make much sense even when I've written it down, much less when I'm doing it and have to remember where I'm at. Is there a better way?

Ur help is highly appreciated.

I need to do something like the following logic: (What I am trying to do is a weight conversion statement)
select
part,
desc,
net_wt,
net_wt_um,
pack_um,
pack_wt,
@somevariable = net_wt / (if net_wt_um <> pack_um then
(if exist(select conversion)
from table1
where field2 = pack_um)
then pack_wt / conversion
else pack_wt
Any thougts? I am basically just looking for a way to do if/else in select statements.
Thanks,
Scott
