Open up a command line python interpreter. Exe ) import pymssql, cx_Oracle, you shouldn't get any errors or response of any kind, just a new ' ' line below. Now on to building the actual script. I'm going to go through the code chunk by chunk and comment on each section as we go, just in case you're new to python, but don't worry i'll have the entire file at the end for download (with comments included in the code). Import string, pymssql, cx_Oracle Define Oracle connection - format username/password@tnsname ora_conn cx_nnect xxxx/xxxx@xxxxx ora_cursor ora_rsor Allocate a cursor Define the mssql server connection - format is self-explanatory mssql_conn nnect(host'xxxx user'xx password'xxx database'xxx mssql_cursor mssql_rsor Allocate a cursor ok, first we've got. Then we're defining the connection string and then defining a cursor that uses each connection - so we're ready for hot sql action. Truncate our destination tables ora_cursor. Execute truncate table test mssql_cursor.

If you've ever done any programming in the past, you'll find that Python is a really easy and flexible language, which makes it very useful for doing just about any back-end task you'd want to accomplish - which (thankfully) includes grabbing extracts from virtually any. I know i've defined the "task" above, but what my example script does specifically (in Part 1) is: Select some rows from an Oracle table (10g) put them into a list, and then use that list to insert them all into destination tables on Microsoft. first we need set up journalism the environment - for this example i'm going to be using a windows box (since we need to connect to a sql server instance), you could do it all with a linux machine too, but for this particular example it'll. I'm using, python.6.2 which is the latest stable release in the.6 tree as of this writing. You can install it from the. Org site using the msi package if you want a nice and easy install. Now we need 2 Python modules for all this shiz-nit to work properly. Cx_Oracle (for, you guessed it, connecting to Oracle) - they've even got a fancy msi for that too. Pymssql (for connecting to microsoft sql server instances) - download the install file and run. Its a lot easier than compiling the module from scratch (esp since doing that requires Microsoft Visual Studio 2008). Once those 2 are installed successfully - lets make sure they work.
In my not-so-humble opinion, you should never trade point-and-click usability and prettiness for rock-solid reliability and flexibility. Note: I'm going to be doing this in a nice and easy step-by-step way - i'm not trying to insult anyone's intelligence, but I find that when people gloss over things because "everyone knows xyz", it alienates people and makes shit downright confusing for others. I want these posts to be a definitive guide, and the only way to do that is be thorough. Ok, here is the task we are completing in this post - writing a simple (non-interactive) Python script to pull data from an Oracle table and insert it into a sql server table (and/or another Oracle database table). You can run it by hand on the command line or schedule it and it will always work the same - all the while using very little overhead. I spend a lot biography of time in an old school Oracle shop and you'd be shocked how many people simply cannot do things this without resorting to ridiculous (and idiotic) methods (writing PL/sql out to a flat file on the server, reading flat file. Think of Python as the "glue" to stick things together (without odbc or other shitty platform-dependent "connection technologies.

In the data Transformation Services (DTS) / Extract Transform and load (ETL) world these days we've got a lot of expensive ass products. Some are good, some are marginal, and some are pieces of over-complicated (and poorly performing) java-based shit. But, hey, thesis enough with the negativity - i digress, i just want to show you that its pretty easy to do the same types of data manipulations in pure easy-to-read python code. Why lock yourselves into an expensive proprietary etl system that requires expensive consultants to maintain (badly)? In this multi-part post I'm going to start with a simple data transport across data platforms (with minimal exception handling and later mix in some fancier etl functions and "robustness" (if that's even a word - i know i've heard Cheese-nip Sales guys use. I guarantee its a hell of a lot faster and more reliable than any of the commercial products out there (I know, because i've use them all).
