I have two tables that have a common column (ID). Now, what i am trying to do is find what is not in one table that is in the other.
For instance:
Table A
ID NAME
1 Tom
2 George
3 Richard
Table B
ID NAME
1 Tom
3 Richard
4 Kevin
With this information, I am trying to write a query that would tell me that Kevin is the only record that doesn't exist in both tables ... like an outlier.
I have tried using something like the following:
SELECT distinct id, name
FROM Table 1 INNER JOIN Table 2
ON Table 1.id <> Table 2.id
Is there some Transformation or other method to remove outlying records based on an attribute during a Data Flow task?
I have a list of Organizations complete with a list of Products they have bought. I am going to do some data mining / profiling off of this data but first I need to get rid of the top 25% and bottom 25% quantity records by Product. I've looked at Percentage / Row Sampling but they are too simple.
Currently, I'm using the following steps to migrate millions of records from Foxpro tables to SQL Server tables:
1. Transfer Foxpro records to .dat files and then bcp to SQL Server tables in a dummy database. All the SQL tables have the same columns as the Foxpro tables. 2. Manipulate the data in the SQL tables of the dummy database and save the manipulated data into the SQL tables of the real database where the tables may have different structure from the corresponding Foxpro tables.
I only know the following ways to import Foxpro data into SQL Server:
#1. Transfer Foxpro records to .dat files and then bcp to SQL Server tables #2. Transfer Foxpro records to .dat files and then Bulk Insert to SQL Server tables #3. DTS Foxpro records directly to SQL Server tables
I'm thinking whether the following choices will be better than the current way:
1st choice: Change step 1 to use #2 instead of #1 2nd choice: Change step 1 to use #3 instead of #1 3rd choice: Use #3 plus manipulating in DTS to replace step 1 and step 2
Is it possible to determine the data size of records in a table. basically I would like to run a select query with a condition and the result will be xKB. I know that this is possible on a database level, but can it be done on a record level (or number of records).
I am trying to update a field within one table with the values from another table. With the criteria that another field in each table are equal. What is the correct way to do this. My syntax is all wrong.
I report SQL Server table information (table names, field names, field datatypes, etc.) to my users using an ACCESS front end. Most of this information exists in the system tables. But I can't find a record count per table in the system tables. What's the fastest way to get a record count for all tables?
Hi! I have 2 tables (both have the same structure): ID -> bigint (identity, not for replication, primary key) Url -> nvarchar(1000) MainUrl -> nvarchar(1000)
Tbl1 cantains about 0,5 mln records, and tbl2 - 1 mln. What I need, is to copy records from tbl2 to tbl1. But records in tbl1 are unique, and it can't change. (Unique must be only "Url"; (and ID, but it's automatic)). How can I do this in fast way? Now I'm using SELECT for each record in tbl2 to see if it exist in tbl1. But it's a bit slow... Is there any faster method? (One thing: I'm beginner in databeses, so I'm wrote VB application to transfer records. How can I do it using only Microsoft Sql server?) -------------- I'm forgot to write, I'm using MsSql 2005.
HiI'm using Access 2002. I have 2 tables tblGroupContact,tblGroupPermission, both have 2 fields identical structure:ContactID GroupID (Both are Composite keys and both hold integers)tblGroupContact holds everybody and the groups they are members of.tblGroupPermission holds only those people who have permission to makechanges to another part of the DB.The SQL at the end of post works, but opens a dialogue box looking fora parameter value 'query1.ContactID'Clicking enter or cancel (without entering anything) works OK.What have I done wrong to cause this parameter request.Thanks ColinKSELECT tblGroupContact.ContactID, tblGroupContact.GroupIDFROM tblGroupContact LEFT JOIN tblGroupPermission ON(tblGroupContact.ContactID = tblGroupPermission.ContactID) AND(tblGroupContact.GroupID = tblGroupPermission.GroupID)WHERE (((tblGroupPermission.ContactI*D) Is Null) AND((tblGroupPermission.GroupID) Is Null));
I need some help with this. I was able to count all the records in ourdatabase using the user_tables and user_tab_columns tables afterrefreshing the statistics on this database.We are doing an upgrade of a system and I will not be able to refreshthe statistics during the upgrade. I need more of a manual process ofrunning these queries.Now I do:select A.table_name, round(A.num_rows,0) as rowcount,count(b.table_name) as ColumnCountfrom dba_tables A, dba_tab_columns Bwhere A.table_name = B.table_name and A.owner in ('PS','SYSADM')group by A.table_name, A.num_rowsorder by rowcount desc, columncount descBut I can't use the num_rows anymore so I was thinking more to do this:Select A.table_name from(select count(*) from A.Table_name B where A.Table_name =B.Table_Name)from user_tableThis does not work for me since I don't know how to pass the table_namefrom the first select to the second select. The logic is there but thesyntax is not.Please help.
Hi,I was just wondering... Is there any built-in function in MS SQL, which willallow me to do rows' "capitalisation"?Lets say that in database.table.name I've got:"FOO BAR LTD.", which I want to change to "Foo Bar Ltd.""Foo bar LTD.", which I want to be "Foo Bar Ltd.".Is there any way of doing this or do I have to read it from database, changein some script, and then insert it back into the table?Hope it's all clear ;-)Thank you,Martin
one table must be deleted based on a filter (I mean the table is not delete completely but only some records), I would like to delete same records in the second table. for ex: table 1: pk: 1,2,3,4,5 table 2: pk: 1,2,3,4,5 table 1: deleting 1,2, 3 thus also in table 2 pk: 1,2,3 must be deleted. At the and of process Table1 and Table2 must have the same records (always also in the case of failure, errors and so on ).
The target is avoid using triggers. OUTPUT is not useful because it writes what is deleted (or may be useful but how to use it?).
I have searched in length and cant seem to find a specific answer.I have a tmptable to hold user "shoppingcart" ( internal supplies)What i want is to take when the user clicks order to take that table pull the records with that user and populate the order and order details tablesThe order table has a PK of orderID and the orderdetails has a FK of orderIDI know how to insert to the main table, but dont know how to populate the details at the same timeI have this.Insert into supplyordersselect requestor from tmpordercart where requestor = &name so how do i also take from the tmpordercart the itemno and quanity and put them into the orderdetails so that it links back to order table?
Hello all, I have a DTS package set up to import a text file on a daily basis. I need to dump the data in 2 table after 7 days of the last import .this is the code that I have Delete From TblTemp date(Day(-7), CurrentStamp). But for some reason it deleting the data right after it imports it. And it doesn't delete anything out of the other table.
I am having a problem in adding new records in SQL 7.0 Database. I have two databases - one with table name DB1..WTEST and the other with table name DB2..TEST. I want to update records in DB2..TEST table when records are already in TEST table (by comparing primary key - with ignore duplicate option) & secondly, INSERT records in DB2..TEST table from DB1..WTEST table if the records do not exist in DB2..TEST table. The first option which is Updation, works fine but with second option I have problem. It works and records are INSERTED but I don't know the statistics of inserted records. Instead it gives a warning message - Duplicate records were Ignored -
Can somebody help me out or suggest some better solution for conditional record insertion. I used CURSOR option but it is only for Updation & Deletion.
IF EXISTS (SELECT * FROM DB1..WTEST INNER JOIN DB2..TEST ON DB1..WTEST.Name1 = DB2..TEST.Name1) BEGIN UPDATE DB1..TEST SET add1 = DB1..WTEST.Add1 FROM DB1..WTEST Print 'Updated' END
WHILE NOT EXISTS(SELECT * FROM DB1..WTEST INNER JOIN DB2..TEST ON DB1..WTEST.Name1 = DB2..TEST.Name1) BEGIN INSERT DB2..TEST SELECT DB1..WTEST.Name1, DB1..WTEST.Add1 FROM DB1..WTEST CONTINUE END

How to write a sql to combine the 4 tables into one without repetitive records? The 4 tables have exactly the same fields.
The tables do not have primary key. The fields to identiry the rows is name and dob. In the case the name and dob is same for two records, the one with latest date_created is selected.
I am trying to delete the records in 2 related tables. The 'child' table has a field called [SETA],
I want to delete all the records in this table that contain the same info, as well all the fields in the parent table that is related to this table. They share the [ID] field as key. This is my code:
Code: DELETE FROM Student a full outer JOIN Qualification b on a.[ID] =b.[ID] WHERE b.[SETA] = @SETA
RID, RType, GID 001, m, g01 002, m, g01 002, m, g02 002, m, g03 003, m, g01 003, m, g03 a, T, g01 a, T, g02 a, T, g03 b, T, g02 b, T, g03 b, T, g04
4. Group
GID g01 g02 g03 g04
I'd like to find the record in table #1 "Matter" which has exact record of "GID" in table #3 "Security Assignment" compare with table #2 "Category"
In this case, it is record of "002" bacause "002" in table#1 "Matter" and the record "a" in table #2 "category" both has exact GID records(g01, g02, g03) in table #3, "Security Assignment"
How can I create qury to find all the possible record in the table #2?
Following is a stored procedure that currently runs on the system (compacted version). I need to combine this data with data from another Table .. tblAdjustments. The schema for this table is fairly close to tblShipmentDet.
Result: combine tblShipmentHdr + attached tblShipmentDet records with tblAdjustments records.
Would the best approach be to use a UNION SELECT?
@XToDate datetime = '7/31/2005' ,@XBegDate datetime = '7/1/2005' AS SELECT SHPH.ProductID, SHPH.ReceivedDate, SHPH.ShipmentNo, SHPD.Vendor, SHPD.Quantity, QRecvdDate = CASE WHEN SHPH.ReceivedDate < convert(varchar(40),@XBegDate,121) THEN NULL ELSE SHPH.ReceivedDate END, QShipQty = CASE WHEN SHPD.TransCd = 'F' THEN NULL WHEN SHPH.ReceivedDate < convert(varchar(40),@XBegDate,121) THEN NULL ELSE SHPH.ShippingQty END, PROD.ProductName, QOpenAccrual = CASE WHEN MEND.OpeningAccrual is Null THEN 0 ELSE MEND.OpeningAccrual END FROM dbo.tblShipmentHdr SHPH LEFT OUTER JOIN dbo.tblProducts as PROD ON Left(SHPH.ProductID,7) = Left(PROD.ProductID,7) LEFT OUTER JOIN dbo.tblShipmentDet as SHPD ON SHPH.ShipmentID = SHPD.ShipmentID LEFT OUTER JOIN dbo.tblMonthend as MEND ON SHPH.ProductID = MEND.ProductID And MEND.MEPeriod = convert(varchar(40),@XBegDate,121) WHERE ((SHPH.ReceivedDate >= '7/1/2005' AND SHPH.ReceivedDate <= '7/31/2005') OR (SHPD.DatePaid >= '7/1/2005' AND SHPD.DatePaid <= '7/31/2005'))
I had 2 tables contain data: 1) old_data: 601,195 records firstname lastname address city state zip zip4
2) current_data: 410,185 records firstname lastname address city state zip zip4 3)Questions: How I write a query make to delete records? From table 'old_data' delete match records reference to table 'current_data' and keep the remain good records are from 'current_data' table.
****Here's below my test query that came up with if there are any error and please provide me any suggestion or new query. Very important task ....Thanks you to all.
/******* Delete current_data From old_data Cross Join current_data Where old_data.FirstName = current_data.FirstName and old_data.LastName = current_data.LastName and old_data.Address = current_data.Address ********/
I would like to build a query that will return all the records in Table1 that will not match with records in table 2. All colums in table 1 have NULL values. Only one column is populated with state abreviations.
SELECT nvl(field1, 0), field2, field3, nvl(field4, 0), nvl(field5, 0), nvl(field6, 0) FROM TBL1 ------------------------------------------- Result: Record count 3000.
Only field3 is populated everything else is null.
select field3 from tbl1 group by field2 - record count = 48
Hi, I have 3 tables: Employees with the fields:idEmployee and employeeName Roles with the fields:idRole and roleName. An employee can have one or many roles. I created the table EmployeeRoles with the fields: id,idEmployee,idRole. idEmployee and idRole are foreign keys. I want to insert a new employee into Employees table, but I have to insert idEmployee field into EmployeeRoles table.
I need to compare records between two tables. There is no ID in the tables to do a simple join between them. So, what I'm looking for is: get the first record from table1 and read all record from table2 and give me back the most similar record. The String Distance is a predefined function.
Select a.table1 ,b.table2 from table1 a, table2 b where StringDistance (''a.table1,'b.table2') >90
Does anyone have a good query that would return records from two tables that are found in one, but not it the other table? In my situation I have 2 tables that are duplicate tables and I need to find an additional 3000 records that were added to one of the tables. I also have a composite key so the query would have col1, col2 and col3 as the composite key. So far I have tried concatenating the 3 columns and giving the result an alias and then trying to show the ones that were not in both tables, but have been struggling. Thanks..
I'm trying to look for an efficient way to select records from two tables, combine them (not just one set above the other) and also efficiently page the results as well as dynamically order by specific columns. So far I have this....
INSERT INTO @Temp SELECT i.ID, i.Name, Type = 'I' FROM Item i UNION SELECT p.ID, p.Name, Type = 'P'FROM Package p
SELECT * FROM @Temp ORDER BY Name ASC
I was going to then implement some sort of of ROW_NUMBER like paging and ordering on the @Temp table variable. Problem is there could be potentially 1000's or more Items and Packages and they would all go in this single Temp table before having records 1 to 10 returned. Is there a more efficient way of doing this before I proceed any further?
Is there any reason why only heaps can have forwarded records while tables with clustered index have to resort to page split when a page becomes saturated with data due to an update or insertion? Both have drawbacks, forwarded records add another level of indirection, leading to increased I/O overhead, while page split may cause further split in the parent pages which can cascade even further. May be that the cascading is a one-time only cost to be incurred, while the indirection overhead repeats everytime there is a query. Then why not go for page split in heap also? The additional overhead to be had for adding another pointer to the IAM page is also one-time.
Using SSE 2012 64-bit.I need to insert records from multiple Access Tables into 1 Table in SSE and ensure no duplicates are inserted.This is executing, but is very slow, is there a faster way?
Code: INSERT INTO dbTarget.dbo.tblTarget (All fields) SELECT (All Fields) FROM dbSource.dbo.tblSource WHERE RecordID NOT IN (SELECT RecordID FROM dbTarget.dbo.tblTarget)
I need to get the replacement records between the 2 tables. I have table A and table B with same structure. I have 5 fields. Table A has 50,000 records and table B has 20,000 records. I have fields id , name, address,meter_flag,end_Date.
Some of the records in Table B are just replacement records of table A. I mean for example I have records like this in Table A
id name address meter_flag end_date
23 john 1201 salt lake dr no 2011-12-28
24 tom 1222 gibson ln yes 2011-12-16

So here in Table B i have an update for john with id 23 in table A in address field and meter_flag has changed to yes. There is new record with id 25 in table b but that is not in table A. so I need to find all these difference records by querying these 2 table
