This sample is very easy , hopefully it is you want
1.Data Source <=Server ip or ServerName
2.Initial Catalog <= DB Name
3.User ID <= Account ID
4.Password <= Account PWD
5.[*****].[dbo].[awards] <= which table you want to find out
SELECT *
FROM OPENDATASOURCE('SQLNCLI',
'Data Source=10.***.***.***;Initial Catalog=B2C**;User ID=****;Password="****"')

How does one get the first name info from a Users table, which has a first name column?
First of all welcome to the community. I suggest you read the guidelines on how to properly ask a question here and you might want to write a title that is relevant to your question.
Now to the question:
Assuming tblUsers is a table in your database and 'first_name' is a column in your table, you can use SELECT followed by the column you want to select.
Lastly, add FROM to select which table you want to select from.
So in your case it would be:
SELECT first_name FROM tblUsers;

I'm trying to clone a table schema and data into a new table, this is what I'm doing:
SELECT * INTO 'ECO7053__settings' FROM base__settings
I keep getting the Undeclared Variable error
EDIT: Also to complete the questions, is this the correct approach? I need to store data for different users; is it better to add an uID field on my tables and filter by that or rather what I'm trying to do, and have different tables one for each user with a prefix? In the example the uID would be 7053 what would be the correct way to handle this situation?
CREATE TABLE ECO7053__settings LIKE base__settings;
to copy the table schema and indices. Then
INSERT INTO ECO7053__settings SELECT * FROM base__settings;
to copy the data.
Use:
SHOW CREATE TABLE base__settings
Copy the create statement and change base__settings into ECO7053__settings (do a search and replace)
Then run
INSERT INTO ECO7053__settings
SELECT * FROM base__settings

I have a specific column, called DELIVER_TO_LOCATION_ID , which is in a table called apps.po_requisition_lines_all
I need to dig into the database and derive the continent from the DELIVER_TO_LOCATION_ID ,
In SQL Developer I can't seem to find a way to do this .
any tips appreciated. thanks
You can use following command-
desc tableName
It'll give you description of table including every column in it having any constraints on it or not like primary key, reference key etc.

I have about 1000 entries in table. It's simple table with 10 columns. Query:
SELECT * FROM my_table
server runs the query, but is processing it for a long time.
P.S. I know this is not enough info, so please comment and I will add what is needed.
Got it. Not related to SQL. Server got overflown by data. Someone was spamming it.
You can try to use TOP. For example try to select 100 rows and look if server still stucks:
SELECT TOP 100 * FROM my_table
