Here is a very basic question that I have.
I have two tables, A and B. Both have a customernumber and a batchid. This combination is unique in both tables.
How can I pull back the records from table A that do not have a corresponding combination in B?
I know I could find the ones that do match and then exclude them using an inner join and subquery, but is there a simpler way?
THANKS!
I have three tables X,Y,Z. Table 'Y' is having foreign key constraints on tables 'X' and 'Z' (which happen to be primary key tables).
I would like to run a query in which I can retrieve rows from Table 'X' only if the matching rows in Table 'Y' have "ALL" their matching rows available in a simple query being run on Table "Z".
The "All" part is very important.
For more clarification, let me give you an example. Table "X" is equivalent to a mathematical "Equation" table which consists of an equation made up of several "Fields". These fields are stored in Table "Z". Table "Y" contains the primary keys from Tables "X" and "Z". i.e. Table "Y" determines what fields are required for an equation to be complete.
I am having a query "Q" on Table "Z" (Fields table) which returns me a bunch of Fields. Now, on the basis of these fields, I want to retrieve only those Equations (Table "X") which have "ALL" their required Fields present in the bunch retrieved by the Query "Q".
I hope I am clear enough.
Does anyone have any solutions???
Hi
I am trying to write a query that will return a full record with a particular distinct field (the rest of the record being the first such record that includes the distinct field).
For example, for the following:
Fruit Like? Colour
Apple Y Green
Orange N Orange
Banana Y Yellow
Grape Y Green
Grapefruit N Yellow
I would want to return (assuming Colour was the distinct field):
Fruit Like? Colour
Apple Y Green
Orange N Orange
Banana Y Yellow
How do I do this? I've tried using a join (of all different kinds) with a subquery that uses SELECT DISTINCT but this doesn't seem to work. I've tried GROUP BY but none of the aggregate functions seem to just take the first found field.
Thanks for any help you can offer.
Hi All
I have a strange request that might not be possible based on the laws of relational databases but I thought I'd give it a try.
I have three tables which for simplicity I will call A, B and C. Table A contains my master records, Table B contains user details and the final table contains some extra data
In my initial search when joining A and B, I return 100 records. I then need to search in table C for these 100 records based on a criteria. the expected result should return all 100 rows for the ones that match and also the ones that do not match. The problem is that in Table C, not all the 100 IDs exist, so there will not be a corresponding record. Unfortunately, our users still want to see all 100 records in the output. Is this possible
As always any help or direction would be appreciated.
writing the query for the following, I need to collapse the continuity. If the termdate for an ID is one day less than the effdate of the next id (for the same ID) i need to collapse the records. See below example .....how should i write the query which will give me the desired output. i.e., get min(effdate) and max(termdate) if termdate is one day less than the effdate of next record.

Our division has approximately 300 employees. We have an annual shift bid where seniority is calculated using Date of Hire. If 2 or more employees share the same Date of Hire then we fall back to Date of Application. Currently the SSRS report does a very simple query and shows all the employees in order of their Date of Hire. If they match then it sorts the matching Date of Hire entries alphabetically by the employee name. It then becomes the task of the scheduler to locatethe entries with the same Date of Hire and manually look up the employees' dates of applications then sort them accordingly and re-write the report.
Goal:
Convert the manual process into an automatic process by modifying the current SSRS report.
Data:
The dataset is "DivDir" which contains the following fields: "EmpName", "DofHire", & "AppDate".
EmpName DofHire AppDate
Adam ...... 12/2/1996 11/15/1996
Bob ..... .... 1/16/1997 12/27/1996
Charlie ....... 1/16/1997 12/12/1996
Dan ...... ... 4/11/2001 3/22/2001
In the above example I want the SSRS report to list the employees in this order: Adam, Charlie, Bob, Dan.How do I do this programmatically using SSRS?
I have data:
Ticket User Priority
A ME 1
B ME 1
C ME 2
C ME 3
D ME 2
E YOU 2
F YOU 1
G ME 3
H YOU 2
H YOU 3
I ME 1
Essentially if Ticket and User are the same I just want the min priority returned.
SO:
Ticket User Priority
A ME 1
B ME 1
C ME 2
D ME 2
E YOU 2
F YOU 1
G ME 3
H YOU 2
I ME 1

Hi,
This is a where clause I am using in a search.
WHERE (ADDRESS_STREET LIKE '%' + @Search + '%' )
I am trying to do a search which returns the most matching record. For example if I have a record with Denver as text . If I search for Denvr the spell error is intended , I will not get the result. How can I create a stored procedure to counter probable spelling errors and return matching results in a ranked order.

How to return only non matching left join records. Currently I am doing a traffic management database to learn sql.
I am checking for all parishes with no associated drivers. Currently I only have 2 of such.
The regular left join

Returns the all the names of the parishes and the first name of the associated drive, followed by the matches, however the two parishes with no matches have null for the first name.

View 4 Replies View RelatedHello,
I have a database with thousands of records that contain personal details of customers. Some of these records pertain to the same customer - however, they have been submitted by different people, so they differ slightly in detail.
I've been looking to see if any of the data mining tools provided by Business Intelligence Studio in SQL Server 2005 will enable me to achieve a high degree of accuracy in matching records that pertain to the same customer. From what I can see, these tools seem more suited to making general predictions based on large groupings rather than the kind of precise prediction I am looking for.
So I'd appreciate it if anyone could tell me if there is any way I could use Business Intelligence Studio to match these 'duplicate' records together, or whether I will have to create a more SQL-based solution which attempts to match the customer records using SELECT statements and making assumptions about the data.
TIA,
Kweri
Problem:
I am working on a price comparison system which matches the best prices for a purchase (or an order) from exisiting purchase data.
The order is stored in multiple tables including order details (stores major items purchased: e.g., PC) and order sub-details (optional items purchased with the major items: e.g., speakers, backup device, webcam etc.).
There could be a number of major items in an order and each major item could have multiple related sub items. The other variables that affect the price include trade-ins if any, sales going on at the time of order, number of units etc.
Now, for any new configuration (major items/related sub items), the system should be able to return a list of previous purchases made with similar configurations, and similar variables (quatities, trade-ins etc). Even if the same model is not present, similar pcs by the same vendor should be considered. etc etc.
Questions:
Is this possible using Data mining?
If yes, which algorithm is recommended?
Also, can I assign/modify any kind of weights to certain variables (if same model: .6 ; if same model not available but pcs made by same manufacturer available: .3 ; by other manufacturers: .1)?
Any help will be greatly appreciated.
Thanks,

Hi Gurus!!!
I have two tables tabl_a and tbl_b
now tbl_a has some records which are not in tbl_b. I want to update tbl_b with records in tbl_a
eg:
tbl_a tbl_b
a a
b b
c c
d d
x
y
z
Now I want to update tbl_b with records 'x', 'y', 'z'. I want to keep the matching record just untouched.
Something similar.
How can I do that???
Thanks in advance!!!
I am doing some analysis on our customer base and their payment profiles. I have generated two profile strings, one for whether the balance of an account has gone up or down and one for the size of the balance in relation to the normal invoice amount for the customer. So (for example) the balance movement string will look like this:
UUUDUUUDUUUD-D00 Where U = Up, D = Down, - = no change and 0 = no change and no balance
I want to analyse these strings in two ways. The first is that I want to find customers with a similar pattern: in the example below the first and last patterns are the same, just one out of sync but should be considered the same
Movement Multiple CountRecords
UUUDUUUDUUUD1230123012301175
------------0000000000001163
UDUUUDUUUDUU3012301230121082
The second type of analysis is to find customers whose pattern has changed: in the examples above the patterns are repeated and therefore 'normal' in the records below the patterns have changed in that the first part does not match the second part.
Movement Multiple CountRecords
UUDUUUDUUUUU-----------07
UDUUUDUUUUUU------------7
good way to approach this without either a cursor or a hidden REBAR. The challenge as I see it is that I have to interrogate every string to find out if there is a repeating pattern and if so where it starts and how long it is (heuristic because some strings will start with a repeating pattern and then the pattern may change or deteriorate) and then compare the string for N groups of repeating characters to see if and when it changes and I can't think of an efficient method to do this in SQL because it is not a set based operation.

My Tables are in SQL 2005. I was thinking to read the Category records in a Data Reader and within the While Loop, call a SP to retrieve the matching records from Products Table. If matching records found, call System SP_Mail to send the E-mail. The drawback with that for every category records (Within While Loop) I need to call my SP to get Products Data. Will be OVERKILL?

I have an Excel file which contains some data. I want to load that into a SQL server Table. Here are my conditions :
1. If the table doesn't have any matching records from the Excel file, then my DFT should load the data from that Excel to the Dest Table.
2. If the table has even one or more matching records, then the DFT should not process at all, instead I should send an email to the business stating that there are some matching records and hence the package is not process...ed.
P.S. If i use Lookup, I have two matching and non-matching output. which will process the non matching records into the table and matching can be redirected to any flat/Excel file. But i don't want to do this. I just want to lookup the Sql Server table and excel.
It'll be good if there is an additional option in the Lookup "Fail component on matching records".
Following is the query that I'm running:
create table a (id int, name varchar(10));
create table b(id int, sal int);
insert into a values(1,'John'),(1,'ken'),(2,'paul');
insert into b values(1,400),(1,500);
select *
from a
cross apply( select max(sal) as sal from b where b.id = a.id)b;
Below is the result for the same:
idname sal
1John500
1ken500
2paulNULL
Now I'm not sure why the record with ID 2 is coming using CROSS APPLY, shouldn't it be avoided in case of CROSS APPLY and only displayed when using OUTER APPLY.
One thing that I noticed was that if you remove the Aggregate function MAX then the record with ID 2 is not shown in the output. I'm running this query on SQL Server 2012.

Hello,
I m writing a stored procedure to query a table Population that has the following fields - CityId, CityName, Plus0, Plus10, Plus20, Plus30, Plus40, Plus50, Plus60, Plus70, Plus80. The field Plus0 contains the number of people of age > 0 living in the city, Plus10 contains the number of people of age > 10 living in the city and so on. Given the city id and age groups like 20To40, 50To60, 40Plus, etc., I should be able to query the number of people in the city corresponding to the requested age group. Note that if the requested age group was 20To60, I need to make use of only 2 fields Plus20 and Plus60 in the table to compute this value. And if the requested age group was 40Plus, then I need only the value in the field Plus40. The problem is that a wide variety of age groups can be requested like 0Plus, 10Plus, ... , 80Plus, 0To10, 0To20, 0To30, .... 70To80.
Which is the most effecient way to handle this ?
1. Have a stored procedure that returns all the fields even though only 1 or 2 of them would be actually used ?
In this case, if I returned data for a large number of cities then there would be a lot of unnecessary information that was returned by the query. Lots of data would be passed through the network though most of it would not be used.
2. Have a stored procedure that takes in parameters @Plus0, @Plus10, @Plus20, .. @Plus80 that are bits indicating whether the field was required or not and then using a CASE statement to return values for a field only if the corresponding bit parameter was set, and returning NULL if the corresponding bit paramter was not set ?
In this case, I would be returning NULL for all those fields that were not required for a particular age group. This would save some network bandwidth, wouldn't it ?
3. Pass in the age group itself (ex: 0To20) as a parameter to the stored procedure and have lots of IF statements, one for each age group, that return only the fields that are needed for that age group.
This leads to a lot of code repitition.
4. Use a similar approach as above but use dynamic SQL queries to avoid code repitition.
But using dynamic SQL queries can affect the performance of the stored procedure as they need to be compiled each time.
5. Any other possible approaches ??
Looking forward to your responses,
Thanks much,
bmgun.
I was curious...Is there a way to select distinct on a combination of some fields andthe for each record returned also get the other fields of anarbitrarily chosen record matching the fields in the distinct record.For example, if I have a select distinct on say three fields:SELECT DISTINCT Code1, Code2, Code3but the table also has other fields, maybe Foo1 and Foo2, and I wantFoo1 and Foo2 to also be displayed. Since there may be multiplerecords that match a particular Code1, Code2, Code3, then I just wantone of those to be arbitrarily chosen.

I need to associate aggregate gross_revenue with calendar year, but do not have a date field that reflects payment dates, just contract periods a start_date and an end_date. The contract periods are typically 1 or 2 years and can start at any time I.e start_date 6/1/2012, end date 5/31/13. I think by finding the number of days that fall in each calendar year and storing in a temp table, I can create a simple formula to associate revenue to each year.
