Update Tables From A Csv File?
Jul 20, 2005
Hello and thank you for your time. I have never worked with sql
server and currently have a project updating the database.
I have a CSV file as follows:
id
keywords (this field contains commas within)
date
I have a sql server table as follows with only the id populated.
id
keywords
date
How do I update the sql server fields from the CSV file? I'm assuming
I would use an UPDATE statement. What SQL server utility would I use
(I'm very new at this, please be basic)?
Thank you once again,
Sunshine

hi!
I have a big problem. If anyone can help.
I want to retrieve the last update time of database. Whenever any update or delete or insert happend to my database i want to store and retrieve that time.
I know one way is that i have to make a table that will store the datetime field and system trigger / trigger that can update this field record whenever any update insert or deletion occur in database.
But i don't know exactly how to do the coding for this?
Is there any other way to do this?
can DBCC help to retrieve this info?
Please advise me how to do this.
Thanks in advance.

We have 20 -30 normalized tables in our dartabase . Also we have 4tables where we store the calculated data fron those normalised tables.The Reason we have these 4 denormalised tables is when we try to dothe calcultion on the fly, our site becomes very slow. So We haveprecalculated and stored it in 4 tables.The Process we use to do the precalcultion, will get do thecalculation and and store it in a temp table. It will compare the thetemp with denormalised tables and insert new rows , delte the old oneans update if any changes.This process take about 20 mins - 60mins. Ittakes long time because in this process we first do the calculationregardless of changes and then do a compare to see what are changed andremove if any rows are deleted, and insert new rowsand update thechanges.Now we like to capture the rows/columns changed in the normalisedtables and do only those chages to the denormalised table , which weare hoping will reduce the processing time by atleast 50%WE have upgraded to SQL SERVER 2005.So We like to use the newtechnology for this process.I have to design the a model to capture the changes and updated onlythose changes.I have the list of normalised tables and te columns which will affectthe end results.I thought of using Triggers or OUTPUT clause to capture the changes.Please help me with the any ideas how to design the new process

I have a trade data tables (about 10) and I need to retrieve information based on input parameters. Each table has about 3-4 million rows.
The table has columns like Commodity, Unit, Quantity, Value, Month, Country
A typical query I use to select data is "Select top 10 commodity , sum(value), sum(quantity) , column4, column5, column6 from table where month=xx and country=xxxx"
The column4 = (column2)/(total sum of value) and column 5=(column3)/(total sum of quantity). Column6=column5/column4.
It takes about 3-4 minutes for the query to complete and its a lot of time specially since I need to pull this information from a webpage.
I wanted to know if there is an alternate way to pull the data from server ?
I mean can I write a script that creates tables for all the input combinations i.e month x country (12x228) and save them in table (subtable-table) with a naming convention so from the web I can just pull the table with input parameters mapped to name convention and not running any runtime queries on database ??
OR
Can I write a script that creates a html files for each table for all input combinations save them ?
OR
Is there exists any other solution ?

hi all;
1. Excel file Source--> monthly Revenue details
2. Derived Colum Transoformations
3. Oledb Destination
its my flow in one of my packates (ETL job)
Excel file contains monthly revenue details, i wanna import the excel data to my database staging table, so i've created the package.
its working fine...
Problem
if we change the new data for the next month and running the package its not running;
the same file, same format, only we delete the contents, of the file except first row of the excel sheet,
and pasting the new data;
new data is coming from Oracle DataBase in the form of excel sheet ( manually they will copy the data and sending to us)
i open that package in design mode and while double clicking the excel file source it says <column name>'s Meta Data needs to be synchronized
Do you want to Fix this issue automatically with the available external column's meta data
Clearly noted that its a data type issue; i have changed the corresponding data types as it is in the previous Excel sheet which is equivalant to the Table its copying to.
now the package is running with validation warnings, External Column "Invoice Amount" needs to be updated...etc. some 2 or three warning messages i can able to see in the package Execution wizard,
ok, i'm ready to accept these warnings, and i want my package running from my server;( packages had been deployed in to the Centeralized server; every time if we want to run the package, we have the asp.net webpage, that is executing the package in an On_click event)
The package is not running from the server, its due to the meta data change in the Excel file( i guess)
please suggest me some guide lines to resolve this meta data issue, i want my excel sheet meta data should not change when we have new updates in it;
otherwise suggest me some solutions that i can validate the excel sheet before running the package and testing whether the data is in correct format or not? its a kind of Data Profiling activity;
i know its some what crazy, but i need to maintain the system with permanent solution, instead of facing this meta data mismatch issue!!!
some what lenthy explanation--> its needed for my dear powerful microsoft responders. i think i 've explained my problem clearly, if i don't let me know your queries, i'll try my level best.

SET @RowCnt = 1
SET @date = CONVERT(CHAR(10),GETDATE(),110)
SET @ArchPath = '\D$EDATAWorkFoldersSendSendData'
SELECT @TotalRows = count(*) FROM table1
--select @ArchPath
WHILE (@RowCnt <= @TotalRows)
BEGIN
SELECT @AccountNumber = AccountNumber, @output_filename FROM table1 WHERE Identity_Number = @RowCnt
--PRINT @AccountNumber --test
SELECT @sql = N'bcp "SELECT h.HeaderText, d.RECORD FROM table2 d INNER JOIN table3 h ON d.HeaderID = h.HeaderID WHERE d.ccountNumber = '''
+ @AccountNumber+'''" queryout "'+@ArchPath+ @output_filename + '.txt" -T -c'
--PRINT @sql
EXEC master..xp_cmdshell @sql

Hi,
I have 2 database tables with column "city". When I update one of these two I want to be updated all the records in the other table. For example:
In table "a", column "city" contains the record "NY"; in table "b", column "city" also contains the record "NY" several times. When I change "NY" to "New York" in table "a" I want that also in table to be changed all the records. The condition is not to use foreign key, but just the text of the records.
Any help would be appreciated,thanks.

I have an package that goes out and downloads information from an Informix Database. This Information needs to be replicated in another table. However I cant just delete and insert the information into the table, There are a number of clients updating from this table once a minute. How can I make SQL Serve 2000 update the information based on another sql table ( Sort of like a local replication?). Is there a simply query I can use or do I need to set up another packeage stored procedure. Right now the information is placed in a tempory table, the actual table needing to be updated is cleared of its data, and the information is moved. However this causes latency issues in my program. Also, since the Infromix query can take up to 30 seconds to complete, this leaves some of my users retrieving blank data.

I have 2 tables. They both have the same fields [OFO_Code] and [Description]
Table 1 is Called Qualification and Table 2 OFO_Code. The second table is a lookup table. The info in Table 1 's description column in some places does not match that of Table 2.
I am trying to loop through these tables to Update the info in Table 1's description to match the correct description in Table 2.
Their are 1417 items in Table 2 and 77000 items in table 1.
There are NO errors when executing, just no update
Here is my code so far:
Code:
Update Qualification SET [Description] = B.Description FROM Qualification A INNER JOIN OFO_code B ON A.OFO_CODE = B.OFO_CODE WHERE A.OFO_Code IN ('" & OFO & "' )"

how to update a temp table with another temp table for example I have #tempdashboard that has info in it.I also have #tempappscount of which I want to insert the info inside it into #tempdashboard...I believe the column in #tempdashboad is DailyAppsInINT,
I did a query that gave me the number of daily apps created. I was told to create #tempappscount and my query to dump into #tempappsaccount. Then dump the info from #tempappsaccount into #tempdashboard.

I have a customers CRM DB that I need to run an update query on, affecting around 14,000 records. The fields used in the entity in question are split across two tables. I need to update a field in one tabled based off of the result of a field in the other table.
So this is what I started with:
USE db1
UPDATE tbl2 SET field1 = '1' WHERE tbl1.CreatedOn < '2013-28-09 00:00:00.000';
This didn't work, SQL complained about being unable to bind tbl1.CreatedOn. I assume because it's in a different table to the one I'm updating.
I attempted a JOIN to the best of my limited SQL knowledge, thinking I could just shove the two tables together and it might be happy.
USE db1
INNER JOIN tbl1 ON tbl2.Id=tbl1.Id;
UPDATE tbl2 SET field1 = '1' WHERE tbl1.CreatedOn < '2013-28-09 00:00:00.000';
This also didn't work, complaining of syntax error near 'INNER'
I'm obviously missing something, but IU don't know what it is.

Given the below table relationships, I am trying to update the price of disk by %20 percent that were interpreted by 'Joe Smith'. I took a crack at this, but I do not feel comfortable with it. Do I need to do some type of join or union?
UPDATE Disk
SET price = price *.20
WHERE Interpreter.name = ‘Joe Smith;
MusicalWork (idwork, title)
Piece (idpiece, duration, iddisk, idwork)
Disk (iddisk, brand, type, issuingdate, price)
Execute (idpiece, idinterpreter)
Interpreter (idinterpreter, name, address)

ans writes "I’m using SQL Server
• I’ve got 3 tables: tblOne, tblTwo, tblThree
• Using the stored procedure(let call this stored procedure sp_Result) I generate result using all the above tables(tblOne, tblTwo, tblThree).
• The problem is, it takes too long to execute(around 15 sec), which is not acceptable as I’m using in the result in the web application
• I’m thinking of scheduling to run the above stored procedure to run once every hour and write the result in a new table, tblResult.
• now the user only queries in the tblResult tables. Since it is a straight forward query it will take less than 1 sec. Perfect !!!
• Now the tblResult already exist, and the user are queries only to this table.
• How would I compare the result produced by stored procedure sp_result and the table tblResult?
• How would I update tblResult with the produced result?
• Would be a good idea to write the result in a new table called temp, then drop the table tblResult and then rename the table temp to tblResult?"

I have a mess:
Table1(T1) contains Column1 (C1) which must be appended to Column2 (C2) in Table2 (T2) where an identifying code column(ID) matches in each table. An example of what I want is, where T1.C1 = 'Aluminum' and T2.C2 = 'Material', I would like it to be updated to T2.C2 = 'Material: Aluminum'. I tried this:
UPDATE T2
SET T2.C2 =
(SELECT T1.C1
FROM T1
WHERE T1.ID = T2.ID) + ':' + T2.C2
This did not work out. How should I fix this?
