How To Copy The Content Of 3000 Oracle Tables Into SQLServer?
Nov 9, 2005
I have to copy a large (3000) amount of different tables from a Oracle machine into an
SQLServer machine.
I am able to do this using a (VB) script.
I use now several methods:
1) INSERT INTO TABLE1 SELECT * FROM SID1..DB.TABLE1 (SID1 is a linked server)
2) INSERT INTO TABLE1 SELECT * FROM OPENQUERY(SID1,'SELECT * FROM DB.TABLE1')
3) Also used OPENROWSET method (similar to 2)
For small tables this is fine, however for BIG tables (15M Rows/150Cols) the methods above are too slow.
If I compare the same copy action with a simple DTS, the DTS is 3 times faster.
Also, the DTS seems to bulk copy the data directly into the desired database while the
mentioned methods first fill the tempdb, then the transaction log of the desired database and
then finally the desired table (need very much extra space on your filesystem).
The total size of data is about 300GB.
Can anyone supply me with a simple example how to copy data from an Oracle table into a
SQLServer table in script (or SQL) that is as fast as the DTS and not filling my logfiles??
I read the bcp (which I use for import/export files) and bulk insert commands, but
I do not understand how to use them in this question.
I am racking my brain on this one. I am migrating Oracle data to SQL Server and would like an SSIS package that will copy the oracle data from every table to SQL server. I already have the schema set up in SQL and a straight copy of a specified table works fine between the OLEDB source and OLEDB destination. However, when I set up a loop which sets a global variable for the table names, which are identical on both dbs, and try to set the OLEDB Source and Destination OpenRowsetVariable to the global variable, the process fails with these errors with all validation turned off:
[OLE DB Source [18]] Warning: Cannot retrieve the column code page info from the OLE DB provider. If the component supports the "DefaultCodePage" property, the code page from that property will be used. Change the value of the property if the current string code page values are incorrect. If the component does not support the property, the code page from the component's locale ID will be used.
[OLE DB Source [18]] Error: Column "ID" cannot be found at the datasource.
[DTS.Pipeline] Error: component "OLE DB Source" (18) failed the pre-execute phase and returned error code 0xC0202005.
To sum up, I want to set the tables dynamically and have them infer the mappings. The names of the columns are already the exact same on each schema, and the data types are mapped accordingly. I have already verified that the names of the tables have been formatted correctly for each database. If I can't do it this way then how?
I am new to SQL Server 2005 SSIS Packages. I want to transfer data from multiple tables from sql server to oracle database. I cannot use export wizard as it creates new tables in the destination (oracle) DB. I already have tables created in the destination DB. When I created an SSIS package, it allowed me create package to tranfer data for only for one table from source to destination. I have created DTS packages in 2000, where you have source db and destination db and just add links for multiple tables. Is there a way I can do it in SSIS. Please let me know.
Hello,I need to copy a table from an 8i oracle database to a sqlserver 2000 database.Is it possible to use the command "COPY FROM ... TO ..." ?So, what is the correct syntax ?Thanks for your helpCyril
I am trying to 'load' a copy of a SQLServer 2000 database to SQLServer 2005 Express (on another host). The copy was provided by someone else - it came to me as a MDF file only, no LDF file.
I have tried to Attach the database and it fails with a failure to load the LDF. Is there any way to bypass this issue without the LDF or do I have to have that?
The provider of the database says I can create a new database and just point to the MDF as the data source but I can't seem to find a way to do that? I am using SQL Server Management Studio Express.
Hi all,need advice on the following task:copy the content of a big table from DB_A to DB_B in the same serverthe size of table:~ 7 million rows, ~ 9G in size, 1 clustered pk index, 13 nonclusteredindexcurrent practice:use DTS to copy the data, takes over 20 hours as-- first had to delete existing data of the table in DB_B-- then copy-- all these happen while all indexes are in place.I am trying to check what is the best or most efficient way to copythis kind of data and what wouldbe the expected time for such load.my machine: SQL 2000 Enterprise, 8-way P4, 12G RAM on a EMC Clarrion600 SAN.
Hi, I'm using SQL Server 2005 Management Studio Express. I have a database used for an application and I need another copy of that database so I can fix some bugs. I tried attaching the mdf to the second database but it gives an error.(a database is allready attached) I need the 2 databases on the same server.
need a clue about how to migrate the data from an Oracle applications 11.03 and underlying Oracle 8.05 database to navision 4.0 running sql server 2000
I have 1 table with some empty product codes that I have imported from a txt file. And I would like to fill in the empty product codes by taking the previous product code
I need to implement a file system for an application that allows me to roll back to a point in time. I can do this with either a journaling file system (Unix based such as JFS) or with a database file system such as Oracle Internet File system (now Oracle Content Services). I would MUCH prefer to use SQL Server but cannot find anything that supports this other than a 2000 ppt referencing the then up and coming SQL Server .NET File System.
The application(s) in question are older and store data in proprietary data files and need to access a local (or mapped) drive in standard form (d:programsmyprogram).
Does SQL Server 2005 or 2008 support this type of access? I have searched but cannot find anything to support this.
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")
Hello,I work for an attorney staff, so basically the whole day they aresending themselves a lot and a lot of papers (Word docs or Excellsheets).We are going to propose them the use of a Document Exchange andDatabase System (like Lotus Notes or Oracle Managment Content,formerly known as Internet File System IFS ) with .NET interfazes.Basically the idea is that instead of sending papers the whole day,they can use a software to check and manage more quickly theirdocuments.We are looking for a system that allows us to manage:- Security- Versioning- Folders- Check-in/Check-out- Workflow- Search and Retrieval- Extensible MetadataMy question is:1) Is there any Microsoft tool who can help us to achieve that(management of codes, dates, text, names of documents- I mean like aDocument Exchange and Database System) with .NET interface?2) Or do we have to built it from scratch?Thank you very much!Jorge
we recently got a scenario that we need to get the data from oracle tables which is installed on third party servers. we have sqlserver installed on ourservers. so they have created a DBLINK in oracle server to our sqlserver and published the DBLINK name.
what are the next steps that i need to follow on my sqlserver in order to access the oracle tables ?
I keep product name, id in Table1. I keep Category name, id in Table2. I keep relation between product and category (product_id, category_id) in Table3. I have added some products to the table with proper category. Work fine But for some products I did not specified any category (ie their id is not present in Table3) But now I want all such products (ie all products whose category is nothing) To be associated with category_id 10
Develop on both Oracle 9i and SQLServer 2000 back ends and would like to set up a new test/development server. Are there any issues with running both systems on one box?
Questo Statement in SQL Server funziona.In Oracle PL/SQL se lo lancio funzionaQuando lo devo far funzionare da Vb.net mi si pianta e non va avanti . Stalì a pensare.Come mai ?UPDATE proc_aziendaSET cod_fase_sign = (SELECT MAX(pfa.COD_FASE)FROM PROC_FASE_RIGA pfaWHERE (COD_GRUPPO = 'x09') AND((TIP_DATI = 'I') OR (TIP_DATI = 'S')) ANDpfa.cod_processo = '02')WHERE cod_gruppo = 'x09' ANDcod_processo = '02'C'è un'altro Statement:UPDATE proc_aziendaSET cod_fase_sign = FaseFROM (SELECT ep.cod_processo,app.cod_azienda,MAX(cast(ep.cod_fase as int)) as FaseFROM esp_proc_prospetti ep,APP_PROSP_AZ_8377 app,(SELECT pa.cod_processo,pa.cod_azienda,pa.cod_fase_signFROM proc_azienda paWHERE pa.cod_gruppo = 'x09' andpa.cod_processo = '05' andpa.cod_fase_sign is nullGROUP BY pa.cod_processo,pa.cod_azienda,pa.cod_fase_sign) pnullWHERE ep.cod_gruppo = 'x09' andep.cod_processo = app.cod_processo andep.cod_processo = pnull.cod_processo andep.cod_prospetto = app.cod_prospettoGROUP BY ep.COD_PROCESSO,app.COD_AZIENDA) FaseAzienda ,proc_azienda paWHERE pa.cod_gruppo = 'x09' andpa.cod_processo = FaseAzienda.cod_processo andpa.cod_azienda = FaseAzienda.cod_aziendaQuesta sintassi sembra regolare per SQL Server ma non per ORACLE.Come deve essere ... ?Grazie milleS.
In Oracle we have a datatype called 'ROWID' - Oracle uses this datatype to store the address (rowid) of every row in the database. Do we have any equivalent datatype in SQLServer similar to this ?

Hello,I would like to know if the equivalent Oracle rownum exist inSQLServer. Here is a sample SQL code to explain what I want to do :selectjobs.name,jobs.job_id,jobs.description,hist.message,hist.step_name,hist.step_id,hist.run_status,hist.run_date,hist.run_time,hist.run_durationfrommsdb.dbo.sysjobs jobs,msdb.dbo.sysjobhistory histwherejobs.job_id=hist.job_idand hist.job_id='E71CCB97-81C3-46E2-83FA-BFFCB66B47F8'order byrun_date, run_timeI just want the first or second row returned by this query. In Oracle Ican simply add rownum=1 or rownum=2 in the where clause to obtain thedesired answer. I don't know how to do in SQLServer.Thank in advance,Pierig.
