I'm in the process of doing a major data clean up and I'm just wondering how I would go about eliminating some redundant data.
The Table Layout
Contracts
CNTRID CONTRACTNUM STARTDATE CUSTOMNUM
=======================================================
0 1234567 091885 A
1 1234567 091885 A
2 1111111 111111 B
3 1234567 081205 A
Equipment
EQUIPID DEVICENAME CNTRID CUSTOMNUM
=======================================================
0 DEVICE1 0 A
1 DEVICE2 2 B
2 DEVICE3 1 A
3 DEVICE4 3 A
You will notice that each customer may have multiple devices. Each device may be tied to a contract, and each contract may have one or more devices tied to it.
In the example above, you will notice in the contracts table the contracts with the IDs 0 and 1.
Fig 1.
CNTRID CONTRACTNUM STARTDATE CUSTOMNUM
=======================================================
0 1234567 091885 A
1 1234567 091885 A
These contracts have the exact same information.
Furthermore, if you look down the table you will notice the contract with the ID 3.
Fig 2.
CNTRID CONTRACTNUM STARTDATE CUSTOMNUM
=======================================================
3 1234567 081205 A
This contract shares the same contract and customer number, but has a different start date.
Now lets take a look devices in the equipment table that refer to these records.
EQUIPID DEVICENAME CNTRID CUSTOMNUM
=======================================================
0 DEVICE1 0 A
2 DEVICE3 1 A
3 DEVICE4 3 A
You will notice that DEVICE1 and DEVICE 3 refer to the contract records that contain identical data. (As shown in 'Fig 1')
My question is as follows:
How do I eliminate the any duplicate records from the contracts table, and update the records in the equipment table with id of the left over contract.
Results Should be as follows:
Contracts
CNTRID CONTRACTNUM STARTDATE CUSTOMNUM
=======================================================
0 1234567 091885 A
2 1111111 111111 B
3 1234567 081205 A
Equipment
EQUIPID DEVICENAME CNTRID CUSTOMNUM
=======================================================
0 DEVICE1 0 A
1 DEVICE2 2 B
2 DEVICE3 0 A
3 DEVICE4 3 A
Any help you may provide would be greatly appreciated!
I am new to sql server and I am having deficulties writing sql script to perform the following: 1) Merging data from two tables A and B 2) Eliminate duplicate present in table B (Conditions to satisfy for dublicate:If similar address is found in both tables AND class type in Table A =1 3) merge data related to dup(eliminated records) to new table. Not sure if we can eliminate records first before merging two tables. Tables are as follow:
Table A Fields: ID, NAME, Address, city, zip, Class type Value:123, John, 123 Main, NY, 71690,1 Value:124, Tom, 100 State, LA, 91070,0
Table B Field: ID, NAME, Address, city, zip, Class Type Value:200, Tim, 123 Main, NY, 71690,0 (duplicate; satisfied both conditions and left out in final table) Value:124, Jack, 100 State, LA, 91070,0 (same condition but second condition is not met) Value:320,Bob, 344 coast hwy, slc, 807760,0
Final Table: Field: ID, NAME, Address, city, zip, Class Type Value:123, John, 123 Main, NY, 71690,1 (should also show t Value:124, Tom, 100 State, LA, 91070,0 Value:124, Jack, 100 State, LA, 91070,0 Value:320,Bob, 344 coast hwy, slc, 807760,0
Table d:(relate to table A:showing all products that are related to table A) table_A.ID, Products 123, Paper 1 123, paper 2
Table e:(relate to table B: showing all products that are related to table B) table_B.ID, Products 200, Paper 3
Final Table: ID, Product 123, Paper 1 123, Paper 2 123, Paper 3 (changing table b id to table a)
Would appreciate any help writing script to perform such transformation. Thanks
Hi i have a table value which contains value ----- a a a b b b c c c

I tried using distinct.But OLEDB returns error that invalid syntax.It doesn't support distinct keyword.Actually i read these table from a file thru OLEDB.Not from a database.Any idea ? Thanks in Advance
This above query returns all requests that meets atleast one criteria. How do i edit my query such that i get requests that meet both criteria and the result set looks like below
Yes, I know this subject has been exhausted, but I need help in locating the discussion which took place a few months ago. Sharon relayed to the group a piece of software (expensive) which would help in my particular situation. I grabbed a demo and have gotten the approval for purchase. Unfortunately, I don't have the thread with me at work.
The problem:
Number Fname Lname Age ID 123 John Franklin 43 1 123 Jane Franklin 40 2 123 Jeff Franklin 12 3 124 Jean Simmons 39 4 125 Gary Bender 37 5 126 Fred Johnson 29 6 126 Fred Johnson 39 7 127 Gene Simmons 47 8
The idea would be to get only unique records from the Number column. I don't care about which information I grab from the other columns, but I must have those fields included. If my resultant result set looked as follows, that would be fine. Or any other way, as long as all of the fields had information and there were only unique values in the Number field.
Number Fname Lname Age ID 123 Jeff Franklin 12 3 124 Jean Simmons 39 4 125 Gary Bender 37 5 126 Fred Johnson 39 7 127 Gene Simmons 47 8
If anyone remembers this discussion, mainly the date, I would really appreciate it.
I have two tables, one contains all work orders, the second contains records on work orders that are linked to customoer orders. I'm trying to create a query that will return specific fields from the table that contains orders in the linked order table, and only the work orders in the all order table that (work_order) do not exist in the linked order table (demand_supply_link). I have tried several queries and cannot get the results I desire. Here is the query I am currently trying.
SELECT DISTINCT WORK_ORDER.DESIRED_WANT_DATE as 'Want Date', DEMAND_SUPPLY_LINK.SUPPLY_BASE_ID as 'WO Id', WORK_ORDER.DESIRED_QTY as 'End Qty', DEMAND_SUPPLY_LINK.SUPPLY_PART_ID as 'Part Id', CUST_ORDER_LINE.CUSTOMER_PART_ID as 'Cust Part', OPERATION.RESOURCE_ID as Resource, PART.DESCRIPTION as Description, CUSTOMER.NAME as Name FROM ((((DEMAND_SUPPLY_LINK INNER JOIN CUST_ORDER_LINE ON DEMAND_SUPPLY_LINK.DEMAND_BASE_ID = CUST_ORDER_LINE.CUST_ORDER_ID) INNER JOIN WORK_ORDER ON DEMAND_SUPPLY_LINK.SUPPLY_BASE_ID = WORK_ORDER.BASE_ID) INNER JOIN OPERATION ON WORK_ORDER.BASE_ID = OPERATION.WORKORDER_BASE_ID) INNER JOIN PART ON WORK_ORDER.PART_ID = PART.ID) INNER JOIN (CUSTOMER INNER JOIN CUSTOMER_ORDER ON CUSTOMER.ID = CUSTOMER_ORDER.CUSTOMER_ID) ON CUST_ORDER_LINE.CUST_ORDER_ID = CUSTOMER_ORDER.ID WHERE WORK_ORDER.DESIRED_WANT_DATE Is Not Null AND OPERATION.RESOURCE_ID in ('ASSY','FAB 1','PLAY TRK') AND WORK_ORDER.STATUS='R'
UNION SELECT distinct work_order.desired_want_date as 'Want Date', work_order.BASE_id as 'WO Id', work_order.desired_qty as 'End Qty', work_order.part_id as 'Part Id', operation.resource_id as Resource, part.description as Description FROM WORK_ORDER INNER JOIN PART ON PART_ID=WORK_ORDER.PART_ID INNER JOIN OPERATION ON WORK_ORDER.BASE_ID=OPERATION.WORKORDER_BASE_ID WHERE WORK_ORDER.DESIRED_WANT_DATE IS NOT NULL AND OPERATION.RESOURCE_ID IN ('ASSY','FAB 1', 'PLAY TRK') AND WORK_ORDER.STATUS='R'
This is the error I receive: Server: Msg 205, Level 16, State 1, Line 1 All queries in an SQL statement containing a UNION operator must have an equal number of expressions in their target lists.
The all orders table (work_order) will not have the other fields to link to as there is no customer order linked to them.
Can someone tell me the best procedure when trying to find duplicate records within a table(s)?
I'm new using SQL server and I have been informed that there maybe some DUPS within unknown tables. I need to find these DUPS.
If someone can tell me how to perform this procedure I would apprciate it. And if you reply can also include examples that i could follow for my records.
Table1 has shop# and shop_id. Every shop# should have only one shop_ID. There has been a few data entry errors where a shop# has duplicate a shop_id. How to write a query for shop#s that have more than one shop_id?
Not so sure how simple this question is but here is what happened. I installed SQL Server 2005 on a new Win Server 2003. I exported the tables and their data from the old machine to the newly established database on the new machine.
It looks like all my records were duplicated. When I try to delete one of the duplicates it won't work because both rows are effected. I can't set my primary key now and if I try to create a new database with the primary key already set than the import fails.
Any one run into this before or know what's going on?
Hi,I have written a web application using dreamweaver MX, asp.net, and MSsql server 2005.The problem I am having occurs when I attempt to edit a record. I have setup a datagrid with freeform fields so that the user can click on edit, make the required changes within the data grid then click update. The data is then saved to the database. All this was created using dreameaver and most of the code was automatically generated for me.The problem is that, not everytime, but sometimes when I go to edit a record once I hit the update button to save the changes the record is duplicated 1 or more times. This doesnt happen everytime but when it does it duplicates the record between 1 and about 5 times. I have double checked everything but cannot find anything obvious that may be causing this issue. Does anyone have any suggestions as to what I should look for? Is this a coding error or something wrong with MSsql? Any ideas?Thanks in advance-Mitch

I was wondering if anyone can tell me an easy way to find duplicate records on sql. The thing is this, at work we have a database (table) which includes tracking numbers, I need a easy way to be able to search this table for duplicate tracking numbers and print them out. I currently access this table to edit some data by using the following path “Start > Programs > Microsoft SQL Server > Enterprise Manager” then work my down the tree to “Databases > Master > Tables” on tables I do a right click and “open table/query”. Any help would be most appreciated. Believe me I’m very “SQL illiterate”

Can someone help me out with the sql statement??? I'm running SQL Server 6.5.
and generating a report from an SQL table, and need to know how to exclude records that are "duplicates". Not duplicates in a sense that every field is identical, but duplicates in a sense where everything except the unique identifier is identical. Is there a quick and easy way to do this?
