Basic Table Update/append Question
May 12, 2004
I'm new to SQL server. I want to add or append a unique set of rows to a destination table from a source table, they are essentially the same table by definition. The source table is updated every hour via DTS, all rows deleted and new set added. Both tables have the same primary key. Approximately 40 unique rows are created each hour and I would think the best approach would be to append the new rows to the destination table. I think an Append query will run into a primary key conflict.
In Access, I did this within VB by checking the max value of the primary key and then running the append for any values greater than that.
In SQL, I'm not sure if this should be done as a stored procedure or if there is an easier approach altogether.

I have a series of .csv files created by a parts system. The .csv filename is in the format partnumber.csv The csv file contains a date column and 6 other fields. Each csv file is about 4000 records and there are approx 7000 .csv files that get re-generated once a week.
I'm using c# SqlBulkCopy object to import the csv file into a temp table. No problem there. It works realy fast.
What I need now is a way to move the data from the temp table to the final table and append the partnumber. I'm thinking it would be easy to pass the partnumber in as a paramerter to a t-sql query but not sure how to write the query itself.
I also want to check if the partnuber/datestamp combination from the temp table already exists in the final table and skip it if it does. So I suppose I ultimately need an update query.
Once I have that query written it's easy to import a .csv, launch the update query, wipe the temp table and repeat with the next .csv file.
Temp Table Layout: DateStamp(datetime), Field1 ... Field6(all real's)
Final Table Layout: PartNumber(varchar), DateStamp(datetime), Field1 ... Field6(all real's)
TIA.

I have a database that is being used as sort of a reports datawarehouse. I use DTS packages to upload data from all the differentsources. Right now I have it truncating the tables and appending withfresh data. I was considering using updates instead and my question waswhich is more efficent?

I need to write a single query that will append the values from one table into another table but I need to update a single field in the table with a static value. What I'm working with is an Access .adp with an SQL 2000 backend. The database is used to track ticket sales, payments, and contact info for season ticket holders. Prior to upsizing, each year the database would be copied and then choice bits modified for the next year.
In other words, the history was in several databases, i.e. db2001, db2002, db2003 and for the current year dbcurrent. I decided to create a historic tables in the current DB rather than have umpteen DBs on my SQL server.
My problem is that I need to create a query that appends to my table the previous years data and then updates the season field to reflect the season that the data came from.
In short, say I have a table named accounts
with fields
account, customer, addr1, addr2, ..., ticket type
and I want it to end up in
account_hist with fields
account, customer, addr1, addr2, ..., ticket type, SEASON
and make the season equal say 8 which represents the 8th season the team has played.
I can get both queries to work seperately :D , but for end user ease, I want to perform both actions at the same time :confused: .
Can anybody point me in the right direction?
Thanks

Strange one here - I am posting this in both SQL Server and Access forums
Access is telling me it can't append any of the records due to a key violation.
The query:
INSERT INTO dbo_Colors ( NameColorID, Application, Red, Green, Blue )
SELECT Colors_Access.NameColorID, Colors_Access.Application, Colors_Access.Red, Colors_Access.Green, Colors_Access.Blue
FROM Colors_Access;
Colors_Access is linked from another MDB and dbo_Colors is linked from SQL Server 2000.
There are no indexes or foreign contraints on the SQL table. I have no relationships on the dbo_ table in my MDB. The query works if I append to another Access table. The datatypes all match between the two tables though the dbo_ tables has two additional fields not refrenced in the query.
I can manually append the records using cut and paste with no problems.
I have tried re-linking the tables.
Any ideas?
Thanks,
Brad

All, Using access 2003 frontend and sql server 2008 backend. I have an append query to insert 80000 from one table to an empty table. I get an error:
"Microsoft Office Access set 0 field(s) to Null due to a type conversion failure, and didn't add 36000 record(s) to the table due to key violations, 0 record(s) due to lock violations, and 0 record(s) due to validation rule violations."
I know this error normally comes if there are dups in a field that doesnt allow.

Hi,
I have written a basic UPDATE statement to update two fields in one table using a where clause to identify the record i wish to update. i.e.
UPDATE TableName SET field1=1234, field2='' WHERE primary_key=N'1234';
When i run the statement, in the results window i get a value returned that is equal to the total number of records in that table!! i.e.
(No column name)
--------------------------
588061
but when i check the table, indeed only one record has been updated as expected (and i have confirmed this by using SELECT @@ROWCOUNT straight after)
My question is, why does it do this?? i paniced at first as i thought i had updated ALL rows, but luckily this seems not to be the case.
And can i turn this off??
Many thanks,
Martin

Hi I have a table with the following structure:
Table1
-------
Dept
Filed1
Filed2
Field3
Field4
Field5
I have another table with the following structure
(Basically this table will contain a subset of coloumns of Table1)
Table2
-------
Dept
Field1
Field2
Now using a query I would like see all the records with all coloumns in Table1 plus all the records in Table2 appended
i.e
if Table1 row is
IT F1 F2 F3 F4 F5
and if Table2 row is
IT F11 F22
Sales F12 F23
I would like to see a result set with the following structure
Resultset
IT F1 F2 F3 F4 F5
IT F11 F22 NULL NULL NULL
Sales F12 F23 NULL NULL NULL
Can some body explain me how to do this with a query. I tried using union but it requires identical coloumns on both ends( Ofcourse, we can acheive this by having Field3,Field4 and Field5 as blank columns in Table 2 but I don't wanna do that as my original tables are too huge to handle this).
Any input is appreciated.
Thanks,
Sai

Is there a way to do so on the fly in SQL Server 2000? In other words, a field has the latest update date for the table and we wish to use this date as part of the table name. If so, please provide an example.

How to I make it so that a Authenticated User to a website can append a record to a SQL table. I have watched the video on the asp.net website about using database on a web, it shows how to allow a user to change a record in a database, but nothing I have seen so far shows how they can append a record.
What I am trying to do: I am building a website for a ATV club using Visual Studio 2005 and c#. I am setting up users or members on the site (club members will have a user account, while all others will be un-authenticated users. I am setting up a classifieds area where members can post items for sale, items they are looking for, etc.
I am planning to use roles to allow authenticated users access to a webpage located in a restricted directory. There I want to place a XHTML page which would allow the users to post their classified ads for free. I will have another page that will allow everyone to view the ads not just club members. I want to make this as easy to maintain as possible. I don’t plan on having all the postings come through me to be placed on the web, I want it all automated.

I have a stored procedure that appends data from a temp table to a destination table. The procedure is called from an aspx web page. The destination table has an index on certain fields so as to not allow duplicates.
The issue I'm having is if the imported data contains some records that are unique and some that would be duplicate, the procedure stops and no records are appended. How can I have this procedure complete it's run, passing over the duplicates and appending the unique records? Since the data is in a temp table (which gets deleted after each append) should I run some sort of 'find duplicates' query, and delete the duplicates from the temp table first, then append to the destination table?
Thanks in advance.SMc

In Access I have a macro that, each night, takes a table with aprimary key defined in it, and deletes all the rows. Then itimports/appends records from a fixed width text file. In this way,since the table is not deleted and recreated, the primary key is keptintact.What would be the equivalent SQL method for doing this in an automatedway? I've tried letting DTS import the table from Access, but theprimary key is lost. Is there some way to "empty" a table instead ofdropping it, and then append new records so that the table will end uphaving the primary key I want it to have?Thanks.Larry- - - - - - - - - - - - - - - - - -"Forget it, Jake.

Hi,
Im creatting an SSIS project that uses an Data Flow OLE DB Source to read data from an SQL Table and import it into a Destination table using Data Flow OLE DB Destination. but now everytime I run the project it appends all the rows not the new data rows only. How can I make the application so that it appends only the new data from a source table to a destination table. Is there maybe another Data Flow Control that can copy source table to destination and the next time it runs it only copy new rows. or any other way to do this using SSIS.
Your assistance will be highly appreciated.

Hello,
I was wondering if there was a different approach I should take in appending data to a table...
My destination table has about 94+ million records in it, and I have been taking two approaches to getting new files into this table:
1) I do a data pump task in a DTS to import the file to a trans (temp) table, which is truncated every time, and then do an INSERT INTO statement from the temp table to my destination table.
The import to the trans table only takes a few minutes (about 1 - 2 million records per file, but have short record lenghts,) but when I do the INSERT INTO statement, it takes upwards of 6 hrs to append.
2) I have tried doing a bulk insert task, going directly to the destination table (which defeats the purpose of my trans table to check out the data prior, but I feel the data is clean at this point.)
I am running the bulk insert right now, and it's been running for over 3 hours...so I'm going to assume this will take just as long as the INSERT INTO statement does like I did before.
My destination table does not have any indexes in it at all, and I don't need to do any transformations to the data when bringing it into SQL since the data is clean. Also, I have a default value constraint on one of my fields on the destination table.
Plus there are other ppl and applications hitting the server which could impact the overall processing, but nothing out of the ordinary is going on the server today. I know there are only so many ways to get a file into a table...but maybe someone knows a different way I should try this.
Thanks for anyone's suggestions!
Kael.

Hello. I'm having some difficulty trying to output the results of two seperate queries into the same temporary table.
Does anyone know if it is possible to use the UNION operator to output the results into a temporary table?
Select * From TableA
UNION
Select * From TableB
<---output result to temporary table here--->
Alternatively, is it possible to output the results of two queries in to the same temporary table without the UNION clause?
The following statement fails on the second SELECT INTO due to the fact that #MyTempTable already exists.
Select * INTO #MyTempTable FROM TableA
Select * INTO #MyTempTable FROM TableB
Thanks in advance.

What I would LIKE to do is noted in the subject line. What I'm findingis that "edit SQL" appears to only be an option if I am creating atable. If I select "append to" the option to edit SQL shades itself asunavailable.The reason I'd like this is that there is a datum in the flat file thatindicates whether that record should be appended to that table notedabove. There are other ways of dealing with this "problem" but it wouldbe nice to be able to control it using SQL, in the DTS import/exportwizard.If the source of my data is an SQL table, I can generate an SQL queryto specify what fields to import in an append, to check for existingvalues, etc...Is there a way around this? I can reserve a table for data transfers,regularly overwrite it with new data from text file inputs, and use SQLto insert select fields from that transfer table to other databasetables. (From this "transfer" table, data needs to be inserted intofour separate tables in our database).I hope this is clear. If it CAN'T be done this way, it's okay...just alittle ugly with the need to re-create the transfer table.

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?

I want to append the column to the transaction table(60 million records in it.) ..
Our transaction table is being used in production.. but i have very less amount of time ..
Instead of alter table.. (IF we use the alter to take backup of table and do the processing it will take more time). Is there any way to append the column to the transaction table ..

I have 1 table with a huge amount of data that I recive from someone else in a flat file format. I want to be able to filter through that data and scrub it and find out the good data and bad data from it.
I'm scrubbing the data using different stored procs that i've created and through a web interface that the user can pick which records they wish to create.
If I were to create a new table for clean records, what is the syntax to keep Appending to that table through the data that i'm obtainig via the stored procs that i've created.
Any thoughts or suggestions are greatly appriciated in advance
Thanks again in advance

I'm a horrible noob everyone, so my apologies come up front.
I know Oracle allows me to just do an
INSERT INTO table
SELECT column1, column2
FROM table2
But I cannot get this to work in MS SQL 2000. (See question #3)
Here's my script that I'm trying to execute from Enterprise Manager:
From this table:
CREATE TABLE ISIS_DATA
(ISIS_STATUS_ID VARCHAR(15) CONSTRAINT ISIS_DATA_ISIS_ID_PK PRIMARY KEY,
ISIS_NAME VARCHAR(50),
ISIS_CLASS_EXPIR_DAT VARCHAR(20),
ISIS_SEX_BD_CAT_SCHL VARCHAR(20))
Where this is a sample row of data:
A123456789 THOMAS, CHARLES B. 009/11/01 M05/04/511G
I want to run that data through some substrings etc. and dump it into another table like this:
//THIS TABLE WILL BE WHERE WE PUT THE RESULTING DATA FROM
//EXECUTING THE SUBSTRs AND OTHER FUNCTIONS TO PREP THE DATA FOR BASIS.
CREATE TABLE ISIS_DATA_PREP
(ISIS_STATUS_ID VARCHAR(15),
STATUS VARCHAR(5),
STUDENT_ID NUMERIC(15) CONSTRAINT ISIS_DATA_PREP_STUDENT_ID_PK PRIMARY KEY,
LAST_NAME VARCHAR(25),
FIRST_NAME VARCHAR(20),
MID_INIT CHAR(1),
CLASS NUMERIC(2),
EXPIR_DATE VARCHAR(10),
SEX CHAR(1),
BIRTHDAY VARCHAR(10),
CAT NUMERIC(3),
SCHOOL VARCHAR(5))
Using this script so far:
INSERT INTO ISIS_DATA_PREP
SELECT B.STATUS, B.STUDENT_ID, B.LAST_NAME, B.FIRST_NAME, B.MID_INIT,
B.CLASS, B.EXPIR_DATE,
B.SEX, B.BIRTHDAY, B.CAT, B.SCHOOL, A.ISIS_STATUS_ID
FROM ISIS_DATA A,
(SELECT SUBSTRING(ISIS_STATUS_ID, 1, 1) STATUS, SUBSTRING(ISIS_STATUS_ID, 2, 9) STUDENT_ID,
ISIS_NAME LAST_NAME, SUBSTRING(ISIS_NAME, 5, 1) FIRST_NAME, SUBSTRING(ISIS_NAME, 5, 1) MID_INIT,
SUBSTRING(ISIS_CLASS_EXPIR_DAT, 1, 1) CLASS, SUBSTRING(ISIS_CLASS_EXPIR_DAT, 2, 8) EXPIR_DATE,
SUBSTRING(ISIS_SEX_BD_CAT_SCHL, 1,1) SEX, SUBSTRING(ISIS_SEX_BD_CAT_SCHL, 2, 8) BIRTHDAY,
SUBSTRING(ISIS_SEX_BD_CAT_SCHL, 10, 1) CAT, SUBSTRING(ISIS_SEX_BD_CAT_SCHL, 11, 2) SCHOOL,
ISIS_STATUS_ID
FROM ISIS_DATA) B
WHERE A.ISIS_STATUS_ID = B.ISIS_STATUS_ID
I keep getting this error:
Server: Msg 8114, Level 16, State 5, Line 1
Error converting data type varchar to numeric.
QUESTION #1 - Is there an equivalent in MS SQL 2000 to Oracle's TONUM function?
So, to get around this I change all the fields in the receiving table (ISIS_DATA_PREP) to a varchar so there is no conversion necessary at this time.
Now I get this message:
Server: Msg 8152, Level 16, State 9, Line 1
String or binary data would be truncated.
The statement has been terminated.
I look up this error on MS's knowledge base and get something along these lines:
...Because the truncated string is shorter than the maximum length, the char column that does not allow a null value and the char variable is padded with trailing blanks while the varchar column will not store trailing blanks....
QUESTION #2 -
What am I doing wrong on the field structure on the receiving table of the input command? I experimented by setting all fields to VARCHAR(25) so it would accept more data and not truncate, but still get the same message.
QUESTION #3 -
My main question was for the syntax for INSERTing into a table from another table the rows in MS SQL. Basically copying the data. I have it for Oracle, but MS SQL doesn't seem to take it in that format.
Sorry for the absolutely massive post. : ) And thanks for any feedback.

Hi,
we have records with login.out of employees.
i.e.
this is a set of login/out for an employee for 1 day (but the actual data shows 2 dates )
login 1/1/2005 15:00
logout 1/1/2005 16:00
login 1/1/2005 17:00
logout 1/1/2005 18:00
login 1/1/2005 23:00
logout 1/2/2005 1:00
login 1/2/2005 2:00 <-----------this is the reason why we need a new table called schedules
logout 1/2/2005 3:00 some employee goes over the next day to finish their shift
I think in order to get the proper Start Time and Stop time we need a new table called schedules.
schedules will contain employee work schedules, kindly help me design how to accomplish this.
question is, will it be for each day?
so I'll have 365 record per employee?
help me design the columns
employeeID, startTime,stopTime, workdate -do I need only four?
Thanks.

Hi,
I have a real basic table index question. If I have a clustered index as follows:
CREATE CLUSTERED INDEX [IX_HF1] ON [dbo].[Table1]([Column1],[Column2]) ON [PRIMARY]
and I am querying just on Column2, would it be more efficient and faster, in terms of the query, for me to also have a nonclustered index with just Column2 (as in example below) ?
CREATE INDEX [IX_HF2] ON [dbo].[Table1]([Column2]) ON [PRIMARY]
Thanks,

Let's say you have a Users table, which simply contains a collection of people. Each person has attributes like their password, first and last name, username, etc. It would be useful to track changes to that table over time, so that if an entry is changed, you can simply look at a history table and see which changes occured, and when.
An INSERT/UPDATE trigger works well for this sort of thing, where the trigger inserts all of the 'INSERTED' values into a history table that has basically the same table definition as the Users table. But it gets tricky when considering Deletes.
If my History table entries reference back to the User in the Users table, this means that if I ever want to delete the user, I need to delete all their History first. This means I can't keep records of user deletions, which is significant. The other approach is not to have a foreign key reference in the History table, so that if a user is deleted, I can still keep my History about that user. Including deletes.
I have been timid about doing it this way, since I felt it broke the idea of a well structured database. Is there a better way to approach this? Is there a standard way to set up triggered history to track changes, including deletions, from a table?
Thanks,
-Dan

Code Snippet
Hi there,
I'm struggeling for more than a week now with this problem, without a finding the solution.
I have two databases, MS Access and SQL Server 2005 Express Edition
Using a procedure in Visual Studio i would like to copy all the records from one table in MS Access into an existing table in SQL Server (the tables have the same name and the same layout)
I tried to prepare one Dataset to copy from Access into SQL Server but when i run the command 'DaSQL.Update(DsSQL, "Tabella") nothing happens (not even an exeption has been raised), looking during debug, the DataSet seems filled though...
Please could anyone explain what's wrong and / or is there a more quicker way to copy data from a table to another?
Note i woul have as a final goal to get data from an AS400 database by ODBC, manage it, and put it on SQL Server for a 'data mining' scope (eliminating the use of MS Access, not suited for FE-BE).
the procedure goes like this;
' Create a connection to the MS Access Database
Dim connectionToAccess As New OleDbConnection(DBConnectionAccString)
strsql = "SELECT * FROM [TABELLA]"
connectionToAccess.Open()
Dim DaAccess As New OleDbDataAdapter(strsql, connectionToAccess)
Dim DsAccess As New DataSet("ACCESS")
DaAccess.FillSchema(DsAccess, SchemaType.Source, "Tabella")
DaAccess.Fill(DsAccess, "Tabella")
' Create a connection to the SQL Database
Dim connectionToSQL As New SqlConnection(DBConnectionSQLString)
connectionToSQL.Open()
Dim DaSQL As New SqlDataAdapter(strsql, connectionToSQL)
Dim DsSQL As New DataSet("SQL")
DaSQL.FillSchema(DsSQL, SchemaType.Source, "Tabella")
DaSQL.Fill(DsAccess, "Tabella")
DaSQL.Update(DsSQL, "Tabella")
Note I tried also the following, withou a result;
DsSQL = DsAccess.Copy
DaSQL.Update(DsSQL, "Tabella")
Please is there someone who could respond !!???

I have a sql server 2008 backend with an Access 2007 frontend database. Each time I export a query I get the following error:
Code:
Microsoft Access was unable to append all the data to the table.
The contents of fields in 0 record(s) were deleted, and 1 record(s) were lost due to key violations.
*If data was deleted, the data you pasted or imported doesn't match the field data types or the FieldSize property in the destination table.
*If records were lost, either the records you pasted contain primary key values that already exist in the destination table, or they violate referential integrity rules for a relationship defined between tables. Do you want to proceed anyway?
I don't know what if anything is actually missing because of the amount of data is more thant 6000 records. It seems everything exported but I would have to comb through the data to be sure.

Hi SQL fans,I realized that I often encounter the same situation in a relationdatabase context, where I really don't know what to do. Here is anexample, where I have 2 tables as follow:__________________________________________ | PortfolioTitle|| Portfolio |+----------------------------------------++-----------------------------+ | tfolio_id (int)|| folio_id (int) |<<-PK----FK--| tfolio_idfolio (int)|| folio_name (varchar) | | tfolio_idtitle (int)|--FK----PK->>[ Titles]+-----------------------------+ | tfolio_weight(decimal(6,5)) |+-----------------------------------------+Note that I also have a "Titles" tables (hence the tfolio_idtitlelink).My problem is : When I update a portfolio, I must update all theassociated titles in it. That means that titles can be either removedfrom the portfolio (a folio does not support the title anymore), addedto it (a new title is supported by the folio) or simply updated (atitle stays in the portfolio, but has its weight changed)For example, if the portfolio #2 would contain :[ PortfolioTitle ]id | idFolio | idTitre | poids1 2 1 102 2 2 203 2 3 30and I must update the PortfolioTitle based on these values :idFolio | idTitre | poids2 2 202 3 352 4 40then I should1 ) remove the title #1 from the folio by deleting its entry in thePortfolioTitle table2 ) update the title #2 (weight from 30 to 35)3 ) add the title #4 to the folioFor now, the only way I've found to do this is delete all the entriesof the related folio (e.g.: DELETE TitrePortefeuille WHERE idFolio =2), and then insert new values for each entry based on the new givenvalues.Is there a way to better manage this by detecting which value has to beinserted/updated/deleted?And this applies to many situation :(If you need other examples, I can give you.thanks a lot!ibiza

I have a table where table row gets updated multiple times(each column will be filled) based on telephone call in data.
Initially, I have implemented after insert trigger on ROW level thinking that the whole row is inserted into table will all column values at a time. But the issue is all columns are values are not filled at once, but observed that while telephone call in data, there are multiple updates to the row (i.e multiple updates in the sense - column data in row is updated step by step),
I thought to implement after update trigger , but when it comes to the performance will be decreased for each and every hit while row update.
I need to implement after update trigger that should be fired on column level instead of Row level to improve the performance?
