Where to

I want to find out my Python installation path on Windows. For example: C:\\Python25 How can I find where Python is installed? You need to identify the primary key in TableA in order to delete the correct record. The primary key may be a single column or a combination of several columns that uniquely identifies a row in the table. If there is no primary key, then the ROWID pseudo column may be used as the primary key. I need to know where JDK is located on my machine. On running Java -version in cmd, it shows the version as '1.6.xx'. To find the location of this SDK on my machine I tried using echo %JAVA_HOME% b. Depending on the flavour of SQL you may need to tweak the casts on the order number to an INT or VARCHAR depending on whether implicit casts are supported. This is a very common technique in a WHERE clause. If you want to apply some IF logic in the WHERE clause all you need to do is add the extra condition with an boolean AND to the section where it needs to be applied. If a filter enters in a JOIN condition functionally (i.e. it is an actual join condition, not just a filter), it must appear in the ON clause of that join. Worth noting: If you place it in the WHERE clause instead, the performances are the same if the join is INNER, otherwise it differs. As mentioned in the comments it does not really matter since anyway the outcome is different. Placing the. git config --global --list was also useful for when it doesn't exist as it gave the location of where git is expecting it to be. I have recently started learning Python, and relating to modules: Is there a way to obtain a list of Python modules available (i.e., installed) on a machine? I am using Ubuntu 9.10 (Karmic Koala). With V2, you can create a modules directory in the WindowsPowerShell directory where your profile is. PS will automatically look in that directory to load modules when you run import-module. I created a Scripts directory under WindowsPowerShell as well that is a sibling directory of Modules. I use my profile to set some directories using variables with the following code: Stack Overflow for Teams is now called Stack Internal.
