I am wondering if there is a way to replicate an oracle table over to a sql server table. Both servers are on the same network. I would like to have this automated perhaps using a stored procedure on the sql instance. Is there any way to do this automatically? Or can anyone point me to a good sql script to connect to an oracle db server and export a table file?
You could use an Oracle linked server on SQL-Server. In this way you would use the Oracle data directly from SQL-server.
Take a look at this tutorial: http://blogs.msdn.com/b/dbrowne/archive/2013/10/02/creating-a-linked-server-for-oracle-in-64bit-sql-server.aspx
You can use the Import Data function located under Tasks when you right click on a database in SQL Server Management Studio. It will walk you through picking the Source, the Destination, and how the columns map to each other.

Is there a way to perform a SQL Dump in a SQL Server? Because on mysql we can easily do that with mysqldump command but on a SQL Server when I try to export the data it seems that it's only allowing to export per table and not per database. Now when I try to do the copy database it tries to copy the source db to a destination db. Now I came from MYSQL and I thought that it will somehow behave the same way.
Any idea on how to achieve this?
Thanks for those who will reply
In SQL Server you would either use Backup and Restore, or extract all the schema and data into a .bacpac file.
Is there a way to copy for example one column from MS Access to SQL Server or just a part of the column? I need to copy some rows of one column to SQL Server table just a way I would do this in the MS Excel. There is a great tool for manipulating data for Oracle, named PL/SQL Developer but I haven't found something similar for SQL Server.
Using ETL tools you can achieve your result. If you need opensource ETL tool then you can go ahead with Pentaho PDI. It's free.
I'm trying to query my Hortonworks cluster Hive tables from SQL Server. My scenario below:
HDP 2.6, Ambari, HiveServer2
SQL Server 2016 Enterprise
Kerberos configuration for secure logins in HDP
I was reading about the PolyBase service in SQL Server 2016 and I suppose later versions. However, I realize that according to the documentation what this service is going to perform in SQL Server is a bridge to reach out my HDFS and recreate external tables based in this data source.
Otherwise what I'm expecting is query Hive objects like these would be SQL Server objects as well, such as a linked server.
Someone has an example or knows if this is possible within SQL Server and Hive?
Thanks so much
Hive acts more as a job compiler than a database. This means every SQL statement you are writing will be translated into a job for Hadoop, sent over to the cluster and become executed there. From the user perspective it looks like querying a table.
The already mentioned approach by reading the HDFS data source and re-create it in SQL Server is the correct one. Since both, Hive and database server are different technologies, something like a linked server seems to technically not possible for me.
Hive provides nowadays a JDBC interface which could be used to connect to it. But even with Hive JDBC, every query will end up as cluster job for distributed computing, running over the files in HDFS, create a result set and present that to you.
If you want to querying Hive from SQL server, you can download ODBC driver (Microsoft or Hortonsworks) and create a Data Source Name (DSN) for Hive. In Advanced option check Use Native Query. Then just create new linked server in the SQL server with the same name of datasource as Data Source Name in ODBC driver.
Write openquery something like:
select top 100 * from
openquery(HadoopLinkedServer,
'column1, column2 from databaseInHadoop.tableInHadoop')
I have database in MS Access in which new table is generated to store the records of each day. I want to transfer the data from the current day table to SQL Server Table.
In SQL server I have only one table and Data will append everyday.
What are the possible ways to achieve this functionality.
Thanks
There are many ways you can do this.The one is Import Export Wizard which is listed below:
1) Using Import-Export wizard: This will do is get the data from source (for you will be Access) and put it in Destination database ( which will be SQL Server)
You can call this package through SQL Agent ( you can make it run every day, weekly, monthly)
Import and Export wizard

I would explore creating a Linked Server to Access, and create a stored procedure to load the data, which you could schedule with the Windows Task Scheduler and sqlcmd.

Access has a tool called the Upsize Wizard built directly into the product to help you do this. A second alternative is the SQL Server Migration Assistant for Access, which you can learn about here http://technet.microsoft.com/en-us/library/hh313039.aspx.

I'm wanting to take data from a SQL Server table and populate a Oracle table. Right now, my solution is to dump the data into a Excel table, write a macro to create a sql file that I can load into Oracle. The problem with this is I want to automate this process and I'm not sure I can automate this.
Is there an easy way to automate populating a Oracle table with data from a SQL Server table?
Thanks in advance
I suppose it depends on your definition of "easy".
The most robust approach would be to either use heterogeneous connectivity in Oracle to create a database link to the SQL Server database and then pull the data from SQL Server or to create a linked server in SQL Server that connects to Oracle and then push the data from SQL Server to Oracle.
Yes. Take a look at MS SQL's SSIS which stands for SQL Server Integration Services. SSIS allows all sorts of advanced capabilities, including automated with Sql Server Jobs, for moving data between disparate data sources. In your case, connecting to Oracle can be achieved a variety of ways.
There are three ways to automate this:
1) You can do as Paul suggested and created an SSIS package that will do this and it can be scheduled via SQL Agent,
2) If you don't want to deal with SSIS, you can download the free SQL# (SQLsharp) CLR Library from http://www.SQLsharp.com/ and use the DB_BulkCopy Stored Procedure to do this in a T-SQL Stored Proc which can also be scheduled via SQL Agent. [note: I am the author of SQL#]
3) You can also set up a Linked Server from SQL Server to Oracle, but this has the draw-back of being a potential security hole. Of course, you could use an Oracle Login that only has write-access to that single table (or something similar to that).
There are lots and lots of ways to do it. Which you choose depends on your requirements.
Using Excel is fine if it's a one time thing.
If it's a once-in-a-while thing, then you could write a simple .NET app that uses a single DataSet and multiple DataAdapters to do the data dump. C# code example here.
if it's a regular thing, then you could put the above in a Schtasks task, or you could use SSIS. I think SSIS is an extra-cost option.
if the requirement is for "online access", then a linked database is probably appropriate.
