Want to filter dataset with SQL query using RegEx to filter entries based on the time (hour) e.g. 19:XX or 09:XX. The hour part of the string would be in position 12 and 13.
Checked a few other questions and articles, but I'm very new to this and can't figure it out. Don't know which SQL database it is, but I work with it on Google BigQuery.Thanks for your help!
Screenshot of data entries
The standard way to access the hour in a date/time is:
where extract(hour from timecol) = 19
Not all databases support extract. All should have something similar.

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;
You can read more about SELECT here

I have an application which is taking data from questionnaires users are completing on a website and inputting this into a SQL Lite database.
I'm using Django and would like to display data of users who match closest by selecting similar answers.
How could this be done?
You can add multiple join conditions like this
SELECT *
FROM <table>
INNER JOIN <same table different name>
ON (condition1 OR condition2 OR condition3)

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 want to make auto changes in SQL Server. I have a table which has a column [expires date]. Should I use a trigger or job for this? I want that SQL Server checks those dates every day, and if any of it is < DateTime.Now, it must change a column [IsPremium] of that row.
Add the following statement in your Daily running JOB, if you have. (Your question in unclear. As per my understanding I post this)
UPDATE <tablename> SET
IsPremium = 1
WHERE [expires date] < GETDATE()
