How to apply filter for percentage when it contains strings along with it in SQL Server

Assuming the percentage is less than 100, below code computes the numeric value within the string column and gives you the list of percentages which are less than or equal to 38. This will not work in all cases as the percentage column is not normalized.

ANSWER

Answered 2021-Jan-25 at 17:17

You could use DATEDIFF() to determine the number of days between your StartDate and JoiningDate and evaluate if that is less than or equal to 28 days.

We'll use the ABS() function around DATEDIFF(). That gives us the absolute(positive) value to then evaluate against 28 days.

Oracle SQL Developer - Data Miner Repo - Task failed

Asked 2020-Apr-02 at 00:10

I've been fighting against oracle sql developer for about two days and I just can't get the thing to work.

I would like to learn more about data mining and take a look at their examples and work threw their tutorials, but I cant even get the thing setup.

What I did:

Installed Oracle 12_1 database + oracle_examples.
I then created an administrator account via the oracle sql developer.
- connection name: admin
- username: sys
- password: password
- Role: sysdba
- SID: orcl
- Everything else was left as it is.
I then had to install all the example .sql files manually.
I followed the guide from here: Oracle Install Example Schemas

I did everything exactly the same as the guide told me to do, except I had to do this "hack" command which allowed me to create users. Else I would always get the

ORA-65096: invalid common user or role name

alter session set "_oracle_script"=true;

The new users now show up in every connection that I create in my SQL Developer under "other users". (HR, OE, etc..)

Now I created a new user "dmuser" like the guide told me to do here: (yes - with sql plus)

Oracle create a datamining user

Now I wanted to install the data miner repo. Which should be very easy: Tools, data miner, make visible. And the data miner window showed up. I then added my dmuser connection, double click dmuser to install the data miner repository. I then press start to install the repo and then it says "Task Failed" with the MOST useless error message I have ever seen:

Aight, be prepared for a complicated answer...

Sql developer exectues a .sql file to install the data miner repo. The sql is named "installodmr.sql". Found the info here: Install repo by script

I had a look at the script and what it does. It opens more scripts which insert tables, and users and grant privileges etc...

The problem why the script would not execute correctly was due to a couple of reasons.

1) As mentioned in my question, I can't just create a user, I have to type the command:

QUESTION

how to neglect case sensitivity in os.rename replace

Asked 2019-Oct-21 at 20:14

I have a script that replaces file names with a new filename that I specify, however, right now it is case sensitive (if a filename = DM, but I enter Dm, it is not being replaced)

I already tried filename.lower(), in the os.rename, but it doesn't seem to work. There are no errors though, that filename remains unaltered though.

...

ANSWER

Answered 2019-Oct-21 at 20:14

Your actual file names are not necessarily in lowercase, but you're passing to the replace method a lowercase string of 'dm'. It cannot find the lowercase 'dm' in the file name and therefore returns the same file name, resulting in os.rename doing nothing.

You can lowercase the file name before you call the replace method instead:

How can I get corresponding list values in one dictionary from another python dictionary where they are listed as keys, compare and print out a csv?

Asked 2018-Dec-19 at 18:41

I created a default dictionary from a large amount of data which has values as a list as previewed below. The default_dictionary values are represented as lists in the default dictionary.

ANSWER

Answered 2018-Dec-02 at 14:14

The code below does the following:

Create a new dictionary that holds those records that occur in both of your dictionaries, with each list sorted from lowest to highest 'sum' (I have written it in one expression; for readability you could consider breaking it down into steps)
Go through the new dictionary and see whether the lowest-sum item must have its own line (when it is the only item) or not
Go through the items that must have their own line and output the contents as you formatted them above.

Alternatively you could import it into a DataFrame, to let Pandas handle saving as CSV. I hope this helps.
