I have a cline that is looking to convert an Ingres Database into SQL Server 2008. WE can easily convert the tables but there are a large number of views and procedures that are complex. Does anyone know of a method or tool that can convert these procedures etc without a manual process of doing so.
Thanks
Lee Tedstone.
Lee, I am quite sure there is no such migration tool available at the moment (one that can translate Ingres stored procedures to adequate SQL server ones). Such tool is not trivial to do - one needs to code a language-to-language translator in order to accomplish this.
However, there is a nice (Ingres) project called "Idiom" - http://community.ingres.com/wiki/Idiom - which can give you some clue how to write such translator.
Idiom is used in the Ingres Migration ToolSet project - http://community.ingres.com/wiki/IngresMigrationToolSet - which successfully translates Oracle and MySQL procedures to Ingres.

We are having around 75~ table and 100~ stored procedures. We have created a custom NodeJS app with Sequelize to migrate the tables and its data. But we wanted to migrate the stored procedures too.
The only possible options that we do have is, is to manually convert every stored procedure.
Manually converting each stored procedure is a tedious task. So is there any way other than manually converting the code? I hope someone can guide/help me with this.
FYI:
SQL Server version: 16+
Postgres version: 12+
There soon will be, Amazon is launching an open-source tool under Apache to act as a translation layer between traditional SQL applications and a Postgres database. This translation layer allows your code to operate under its current SQL setup, but it gets translated for the Postgres DB. It's called Babelfish for Postgresql. It's slated for 2021, but it is not currently available. https://babelfish-for-postgresql.github.io/babelfish-for-postgresql/
There is absolutely no possibilities to automatically convert Transact SQL procedures to PG PL/SQL functions because of many lack of functionalities :
PG does not do pessimistic lock that SQL Server uses by default
PG do not support nested transaction that SQL Server support. In
this case the behaviour will be different and the results not the
same.
String data have collations CI/AS by default in SQL Server that PG
do not support completly (ICU collations are not supported for LIKE
and raise an error as an example).
PG does not conform to the SQL Standard regarding the string
datatype. PG use only CHAR/VARCHAR. No NCHAR/NVARCHAR, but strinsg
in PG are NCCHAR/NVARCHAR
PG support function overloading that is not supported in SQL Server.
The function using a generic code with the sql_variant datatype must
be translated into function overloading
PG does not make differnces between function and procedure (which is
a lack of security). SQL Server does it...
There will be many other functionalities that is completly different, and I am writing a series of papers about the differences between PG and SQL Server. The first one is about performances of DBA queries, the secound about COUT performances and the third a complete panorama of functional differences...
First of all, I am sorry because it might be a stupid question but after a day research I am confused and I have a very less time to decide.
We are using TFS as a CI tool and as an SCM. And Postgresql for DB.
Planning to Automate DB with Postgresql and TFS.
Please suggest a tool for this that I can go forward with running my SQL files on specific DB as I want.
Can anyone please tell me if I use DbUp Migration Extension of TFS is it supporting Postgresql? As this link shows it only works with Microsoft SQL Server or Microsoft SQL Azure and then another Document says DbUp supports a number of different databases including Postgresql.
also, Does Flyway have support for c# and TFS ?
Most popular tools to do what you want is Liquibase and Flyway.
As I know there is only one significant difference: Flyway - plain SQL based, Liquibase - provides abstraction level based on XML, JSON or YAML as well as plain SQL. You can use abstractions (provided by Liquibase) to increase portability of your scripts.
I'm planning to play around with Oracle Business Intelligence (for fun). I have access to a number of Oracle products, and may have gone overboard installing them all (quite possibly more than I need).
Problem is I'm not too sure how all the different Oracle components fit together, but I think I am still missing something, a crucial part - DBCA.
All the online help material I can find says use DBCA to create a database - but I don't seem to have DBCA anywhere.
What I do have installed is:
Oracle - OraClient11g_home1
Oracle - OraDb11g_home1
Oracle Business Intelligence
Oracle Weblogic
Does Oracle have a separate Database Server that is not included in the above? (Like MS SQL Server)
I'll note that I am completely new to Oracle and may be missing something very simple, so any help would be appreciated.
I'm looking for an answer that can lead me to how I can install DBCA and create my database but extra kudos for any additional brief information on how these Oracle building blocks work independently and together.
DBCA is the database configuration assistant. It is a wizard used to create a database and should be instaled during the server install. If you are testing you just want to create a database as part of the server insall and ignore dbca.
Oracle - OraDb11g_home1 is the database (most probably at least - given then Oracle naming conventions). DBCA was called as part of the installation process.
Note that a "database" in Oracle terms is something completely different than a "database" in MS SQL Server. A SQL Server "database" is closer to an Oracle schema.
I'm looking for the benefits of upgrading from SQL Server 2000 to 2008.
I was wondering:
What database features can we leverage with 2008 that we can't now?
What new TSQL features can we look forward to using?
What performance benefits can we expect to see?
What else will make management go for it?
And the converse:
What problems can we expect to encounter?
What other problems have people found when migrating?
Why fix something that isn't (technically) broken?
We work in a Java shop, so any .NET / CLR stuff won't rock our world. We also use Eclipse as our main development so any integration with Visual Studio won't be a plus. We do use SQL Server Management Studio however.
Some background:
Our main database machine is a 32bit Dell Intel Xeon MP CPU 2.0GHz, 40MB of RAM with Physical Address Extension running Windows Server 2003 Enterprise Edition. We will not be changing our hardware. Our databases in total are under a TB with some having more than 200 tables. But they are busy and during busy times we see 60-80% CPU utilisation.
Apart form the fact that SQL Server 2000 is coming close to end of life, why should we upgrade?
Any and all contributions are appreciated!
Besides all the features MatthewPK mentions, I also really like:
Common Table Expressions (CTE) (which I find extremely helpful) - see Using Common Table Expressions, SQL Server CTE Basics or SQL Server 2005 Common Table Expressions for more details
Ranking functions like ROW_NUMBER, RANK, DENSE_RANK and NTILE - see Ranking Functions (on MSDN) or New Ranking Functions in SQL Server 2005 for more details
OUTPUT clause in SQL statements to output information about e.g. rows you've deleted with the DELETE statement, or updated with your MERGE statement - see the SQL Server Books Online for more details.
I'm taking care of an old SQL Server 2000 solution, and boy, how many times have I missed those features!
There are a number of reasons to make the migration, I'm sure.
My favorites are:
New DATE datatype (no more having to format strings to compare timestamped dates)
New Spatial Data types (geometry, geography)
New MERGE statement is great for upserts or any other "if exists" type logic
FILESTREAM gets you out of the blob problems (enforced DB integrity on filesystem directories!)
IMHO, from a developer's perspective, the most important upgrade is the TVP
The only shortfall I've personally encountered is that I had to rewrite my DTS packages to SSIS packages (but I think SSIS is great... just more work)
From a purely practical perspective, the most compelling advantages for me are several powerfull TSQL commands that are not available in 2000, e.g. PIVOT/UNPIVOT, and the addition of the intelligent syntax expansion to the 2008 Management Studio that made working with this tool substantially more productive.
Hello,
I'm new here, so sorry, if my question is too basic. However, maybe you have some advice, example, links, which could help me... I'm trying to find something helpfull for few days, but no results as for now.
I'm working in a distributed environment. I have a Oracle server hundreds of miles away and a MS SQL server close to me. I'm writing a application using Visual Web Developer 2008 Express. I need some data from Oracle. It's not worth to query the Oracle server every time i need some data from it. I'd prefer to run some Oracle queries once each night and store results in some local (SQL Server) tables. I assume, I should run queries through standard windows scheduler (Windows Server 2008). I have the basic connectivity - I can open Oracle Database from local Visual Studio.
The questions are:
How to write a query/procedure/function that would get data from Oracle and put them into a SQL Server table (possibly recreated before each query run)?
How can I run such a query from command line (or in other way run from scheduler)
What naming conventions are applicable? In VS I use something like //IP.IP.IP.IP/Name and a user with password.
Thanks for any help or advice.
Regards,
Matteo
I suggest you speak to the DBA's of the Oracle and SQL Server databases, as there may be other considerations you need to bear in mind. (Data Integrity, Security, ownership etc.)
One route you could follow would be to implement DTS (For older databases) or SSIS (for new versions of SQL Server) processes to copy the data across on the schedule you want. (This is pretty much what they were built for.)
How much data are we talking about?
If there is a small quantity that you need to transfer every day, you can write a stupid fetch and insert script in language of your choice.
You only need to search for better solutions if "sync" would take too much resources.
Thanks...
I'm the DBA for the SQL Server, which will serve only for my application. For Oracle I just want to read data and I have enough privileges and agreement with DBA's. Security, ownership and integrity are not an issue for now. I just need some technical advise how to get data from Oracle to MSSQL tables on a schedule.
I use MS SQL Server 2008 Express SP1. I'm very close to solve my problem - I have established connections and everything installed and working. I just don't know, how to run a query, which would get data from Oracle and put into MSSQL, on regular basis, without manual interaction.
I've some experience in programming, but not much in databases (except creating complex SQl queries). Therefore some example or links to detailed description would be helpful. I'm not sure about naming conventions, differences between procedures, functions and queries, command line options to run db automation procedures and so on. I'm also not sure, about which mechanisms or technologies are available in MS SQL Server 2008 Express edition.
