Hi i am streaming data from my apps to Bigquery by C++.
Thing got okay and the all are connectable, but the problem is the log file said there's 665 in streaming buffers
enter image description here
However, final records in the table is just 4. Does anyone know to solve this?

"Estimated rows" are only an estimate.
Streaming data in BigQuery is available in real-time (though table copy commands can take up to 90 minutes). I recommend reading this article for more information.
It sounds like you think you're losing data. That's not likely. I recommend checking what you believe is being inserted versus what's actually landing in the table.

i have 5 gb PostgreSQL dump file. I will restore it by psql command but I have no space on my computer (about 1 gb). I want to know, will the database take over than or equal to 5 gb?
A SQL dump is typically a lot smaller than the restored database, because it only contains the definition of indexes, not the actual index data. So you should expect the database to need at least 5GB after being restored. If it contains a lot of indexes it might be substantially be bigger.
The only situation where a SQL dump might be bigger than the restored size is, if the dump contains a lot of text data that is longer than approximately 2KB. Any text value exceeding that size will automatically be compressed. But still it's very unlikely that the restored size will be 5 times smaller than the dump.

I was executing one normal SP and after that my Tempdb acquired 80GB disk space which was only 8MB before. How can I overcome this? and Why this happened?
It happened because you did something in the SP that needed tempdb. Sorting under certain conditions, the dreaded DISTINCT that needds to know all data for example.
You can overcome this by rewriting your SQL not to use Tempdb. And the current resize you just fix (redefine size, restart server, tempdb is recreated).
Depending on the db, btw, I would NOT consider 80gb to be excessive on a decent modern server. Depends WHAT you do, obviously.

I have basic database table with some rows. see the queries below.
first query selects a record from the database.. you see the result. that result is not the same as the other two result. yet I am retrieving the same record from the table using the different columns/methods.
correct record is the second and 3rd select queries.
PWTransferID is the primary key. PWtransfernumber is non clustered index/Unique
I am really confused and have never seen a problem like this. can anybody shed some light on this for me. almost like the database is broken some where.
Is that just a typo in the first query? Should 227 be 277?

I have a program in C#. I have no question about the C# code but there is something that bothers me. I have been using a trigger in some big transactions in my system. Is it really advisable or good practice to use a trigger in transaction? I have been researching and found that I should use triggers only in audit trails. But I have no problems when using triggers. I'm asking this question because I really want to know your opinion so that in the future if it's not advisable then I can avoid using the trigger in a transaction.
Major drawbacks of using triggers are:
1- Making the whole process slow in large number of transactions
2- Lack/difficulty of control especially for checking the result of the action done by trigger
3- Making your system more difficult to maintain
4- Injection of problems regarding concurrency

How can I prove that images were stolen from a website?
Is there any way to check from when an another website have the same images? I have no any access to the server.
Thanks for any idea!
UPDATE:
No, I'm not the one who forgot watermark. An old client of mine just found me with this question. Actually found Google cached page which we can use, but still interested if any other solution is exist. Like any image format contains any date attribute in it?
If you're using a Unix-based operating system, you might have access to cURL. Try running
curl --remote-time --remote-name http://url-to-your-image/
and see if you get a timestamp that is different from the exact time you downloaded the file. Not all servers respond with the time, but it might be worth an attempt.
But generally, if it's your original work, then you should have a copy of the image with higher resolution and/or lower compression rate, right? That should be enough to prove which of the images is the stolen one. Intellectual property rights on the Internet is a mess, though, for several reasons. But even if you can't take legal actions, you might have better luck convincing an administrator to remove the content.
