Hi,
I have Data split into 3 text files with 3 fields repeated in each to link then (key). I want to import this data into one table.
I used DTS to create 3 tables with the data. Now i want to combine the 3 tables into only one (that i already created). How can i do this? Note: the field names in the source tables are different from the destination table.
Thanks

What's the best way to convert a large set of records from a simple schema where all fields are in one table to a schema where fields are split across two tables? The two table setup is necessary for reasons not worth getting into here.
Doing this via cursor is pretty straightforward, but is there a comparable set-based solution?
Here are sample create table commands. Obviously, the example below is simplified for discussion purposes.
-- One record from here will produce a record in TargetParentRecords and a record in TargetChildRecords for a total of two records.
CREATE TABLE OriginalSingleTableRecords (
ID INT IDENTITY (1, 1) NOT NULL,
ColumnA VARCHAR(100) NOT NULL,
ColumnB VARCHAR(100) NOT NULL,
CONSTRAINT PK_OriginalSingleTableRecords PRIMARY KEY CLUSTERED (ID)
)
CREATE TABLE TargetParentRecords (
ParentID INT IDENTITY (1, 1) NOT NULL,
ColumnA VARCHAR(100) NOT NULL,
CONSTRAINT PK_TargetParentRecords PRIMARY KEY CLUSTERED (ParentID)
)
-- Each row in this table must link to a TargetParentRecords row
CREATE TABLE TargetChildRecords (
ID INT IDENTITY (1, 1) NOT NULL,
ParentID INT NOT NULL, -- References TargetParentRecords.ParentID
ColumnB VARCHAR(100) NOT NULL,
CONSTRAINT PK_TargetChildRecords PRIMARY KEY CLUSTERED (ID)
)
Hello all,
Little layout question. Assume my dataset returns the following data:
A
B
C
D
E
How can I present this data in a table (or list, or matrix) splitted into two columns:
A B
C D
E
Any idea will be very appreciated! Thanks a lot!

I have a source table which I'm splitting 3 ways based on a column value, but the target is the same OLE DB destination table. One conditional path is to a Multi-Cast two way split to same OLE DB gestination table. The default split is to a flat file for logging unknown record types. For a test I have data for only the 3 column values I want, but I'm having trouble with the process completing. If I pre-filter the data going into the source table by one or two values I can get the process to complete even if one split is to the multicast. If I include all three data types in the source table, I get different results depending on the order in which the conditions are specified - sometimes only two split paths are executed; other times all three are executed, but in some cases only one path of the multicast split is executed. In any case, when the three source data types are used in the test, the process never competes - the pathes are in a yellow condition and never complete.
Am I creating some kind of deadlock situation by having the source data directed to the same target table via 4 splits? Any help you can provide is appreciated. Thanks.
Hi All,I'm coming from using MySQL, and in their dialect you could pull data from one table to another using the following: INSERT INTO Table1 (fname, lname)VALUES( SELECT fname, lname FROM Table2 )Let's assume Table1 is a simple table with the fields ID (PK/Identity), fname, and lname. This query would grab all the first and last names out of Table2 (fname and lname fields) and insert them into Table1, generating the ID for each new row.How would I do this in T-SQL?

I am creating a DTS package that is combining several tables, converting one column of data to a new column removing all special characters, then exporting the unique data based on this column and another column, and the max of other duplicates to a new table.
Now that I have the data in this table, I want to import any data that is not in my main table.
This "CLEANED" table does not have a designated "key" column, but the table I want to import the unique items does have an ID column that is also a primary key column.
DTS seems to want me to have a Key column to reference when importing from the CLEANED table to the MAIN table.
How would I go about checking the MAIN table against the CLEANED table, having DTS import only the unique items from the CLEANED table that are not present in the MAIN table based on three columns? The rest of the columns I want to just extract the MAX data from the duplicates.
Now here is the query I use to extract the unique values from the "CLEANING" table to get the data to the "CLEANED" table, but do not know how to use this to import into the MAIN table using something similar.
Code:
select
partno2,
MAX (partno) as partno,
alt,
MAX (C_alt) as C_alt,
Max (cmpycd) as cmpycd,
MAX (type) as type,
compFN,
MAX (pndesc) as pndesc,
MAX (equipment) as equipment
into tbl_CLEANED
from tbl_CLEANING
group by partno2, alt, compFN
ORDER BY partno, compFN
The three main columns I need to check against are:
partno2
alt
compFN
I have named the columns the same in both tables.
partno2 is the column that has been copied from partno with all special characters & spaces removed. This is the main column I am using as a reference for unique values, then if no match, I have it check against the alt column, then the comFN column. If there are no matches in any of these columns, then I want to extract the data to the MAIN table.
How can I compare these tables and import only unique info to the MAIN table?
In addition, how can I also check items that are the same in both tables and update the MAX info for the other columns (not the three I use for reference - these I need to leave alone) and update those if there is more data in the CLEANED table then in the MAIN table?

View 3 Replies View RelatedWhenever I import (or even append from another table) data to a table that has an Identity column, I get an error: Cannot insert NULL values in Identity column.
Isn't the Idenity column supposed to incement automatically without me having to provide a value? Using INSERT provides an Identity value automatically, using import however doesn't.
How can I overcome this problem? (I now delete and recreate the Identity column - really BAD practice!)

I have installed SQL Server Managemert Server Express .... I am wondering how to import data from an excel spreadsheet?
.. Silent Running
So I have been trying to get mySQL query to work for a large database that I have. I have (lets say) two tables Table_One and Table_Two. Table_One has three columns: Type, Animal and TestID and Table_Two has 2 columns Test_Name and Test_ID. Example with values is below:
**TABLE_ONE**
Type Animal TestID
-----------------------------------------
Mammal Goat 1
Fish Cod 1
Bird Chicken 1
Reptile Snake 1
Bird Crow 2
Mammal Cow 2
Bird Ostrich 3
**Table_Two**
Test_name TestID
-------------------------
Test_1 1
Test_1 1
Test_1 1
Test_1 1
Test_2 2
Test_2 2
Test_3 3
In Table_One all types come under one column and the values of all Types (Mammal, Fish, Bird, Reptile) come under another column (Animals). Table_One and Two can be linked by Test_ID
I am trying to create a table such as shown below:
Test_Name Bird Reptile Mammal Fish
-----------------------------------------------------------------
Test_1 Chicken Snake Goat Cod
Test_2 Crow Cow
Test_3 Ostrich
This should be my final table. The approach I am currently using is to make multiple instances of Table_One and using joins to form this final table. So the column Bird, Reptile, Mammal and Fish all come from a different copy of Table_one.
For e.g
Select
Test_Name AS 'Test_Name',
Table_Bird.Animal AS 'Birds',
Table_Mammal.Animal AS 'Mammal',
Table_Reptile.Animal AS 'Reptile,
Table_Fish.Animal AS 'Fish'
From Table_One
[Code] .....
The problem with this query is it only works when all entries for Birds, Mammals, Reptiles and Fish have some value. If one field is empty as for Test_Two or Test_Three, it doesn't return that record. I used Or instead of And in the WHERE clause but that didn't work as well.
I have an existing table I need to add data to. The data is in a text file, and the existing table already has data in it (I don't want to delete this I want to add to it).
I used Microsoft's import utility but this created a seperate table with generic fieldnames (column01, column02, ect). Is there a step in this wizard I missed?

Hi,
I'm about to embark on writing some code in perl or VBscript that automatically synchronises a constantly updated Access database with an MSSQL database.
I know MSSQL has an import tool built into Enterprise manager but I'm wondering if theres a stored procedure that does this?
The way I'm thinking of doing it is to read the all the access tables into separate hash arrays and then INSERTing them into the MSSQL database after checking for any duplicates. This all sounds a bit time consuming (there are a large number of tables) and processor intensive.
If anyones done anything like this before, I'd love to hear their views......!
Thanks!

Hello,I am using SQL 2005 and Cognos' Data Manager. It is an ETL tool fordata warehousing.I have a problem with time it takes to load new changes, and I amseeking advice on a better way to manage the data.I have a table that tracks student attendance and it contains about 13million records. On a daily basis, there are 5,000 - 20,000 inserts and10,000 - 50,000 updates.The daily data comes for two different text files from my operationsystem; current and historical (CLSFIL and CLSHIS).The data is loaded into a staging area from the operational system,where data cleansing and other fields are added to the table.The final step is delivering the table to my target database, which isused for reporting.Heres the situation: I find it takes 45 minutes to do a relationalupdate, where only the records that changed in the last day will beloaded. However, if I choose the native API load instead of aRelational Load, it can load all 13M records in 7 minutes. The table isheavly indexedAt some point, the API load will take more time than the relationalload, (the changes and new records will remain a constant, but the filewill continue to grow).I'm seeking another solution is more efficient. I'm considering twotables for history and current and creating a view for reporting via aunion.This a good idea? How can I make the view effeicent to use the whereclause? Looking to bounce around ideas.Other Ideas?Thanks in AdvanceRob(I maintain the key relationships in the tool, not the tables.

View 3 Replies View RelatedHi all,
Hopefully I am posting this question in the correct forum. I am still learning about SQL 2005. Here is my issue. I have an access db that I archive weekly into and SQL server table. I have used the dst wizard to create an import job and initally that worked fine. field I have as the primary key in the access db cannot be the primary key in the sql table since I archive weekly and that primary key field will be imported several time over. I overcame this initally by not having a primary key in the sql table. This table is strictly for reference. However, now I need to setup a unique field for each of the records in the sql table. What I have done so far is create a recordID field in the sql table that is an int and set as yes to Identify (auotnumber). That worked great and created unique id for all existing records. The problem now is on the import. When I try to import the access table i am getting an error because of the extra field in the sql table, and the error is saying cannot import null value into this field. So... my final question is how can I import the access table into the sql table with one extra field which is the autonumber unique field? Thanks a bunch for any asistance.

Hi Guys
I have an application that runs on several sites that has a table with 36 columns mostly ints och small varchars.
I currently have only one table that stores the data and five indexes and since the table on one location (and others soon) has about 18 million rows I have been trying to come up with a better solution (but only if needed, I dont think I have to tell you that I am a programmer and not an dba).
The db file size with all the indexes is more then 10gb, in it self is not an problem but is it a bad solution to have it that way?
The questions are:
Are there any big benefits if i split it into several smaller tables or even smaler databases and make the SPs that gets the data aware that say 2006 years data is in table a and so on?
Its quite important that there are fast SELECTS and that need is far more important then to decrease the size of the database file and so on.
How many rows is okay to have in one table (with 25 columns) before its too big?
Thanks in advance.
Best regards
Johan, Sweden.

Hello,We maintain a 175 million record database table for our customer.This is an extract of some data collected for them by a third partyvendor, who sends us regular updates to that data (monthly).The original data for the table came in the form of a single, largetext file, which we imported.This table contains name and address information on potentialcustomers.It is a maintenance nightmare for us, as prior to this the largesttable we maintained was about 10 million records, with lesscomplicated updates required.Here is the problem:* In order to do the searching we need to do on the table it has 8 ofits 20 columns indexed.* It takes hours and hours to do anything to the table.* I'd like to cut down as much as possible the time required to updatethe file.We receive monthly one file containing 10 million records that arenew, and can just be appended to the table (no problem, simple importinto SQL Server).We also receive monthly one file containing 10 million records thatare updates of information in the table. This is the tricky one. Theonly way to uniquely pair up a record in the update file with a recordin the full database table is by a combination of individual_id, zip,and zip_plus4.There can be multiple records in the database for any givenindividual, because that individual could have a history that includesmultiple addresses.How would you recommend handling this update? So far I have mostlytried a number of execution plans involving deleting out the recordsin the table that match those in the text file, so I can then importthe text file, but the best of those plans takes well over 6 hours torun.My latest thought: Would it help in any way to partition the tableinto a number of smaller tables, with a view used to reference them?We have no performance issues querying the table, but I need somethoughts on how to better maintain it.One more thing, we do have 2 copies of the table on the server at alltimes so that one can be actively used in production while we runupdates on the other one, so I can certainly try out some suggestionsover the next week.Regards,Warren WrightDallas
