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?

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?
enter image description here
"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 cannot do queries. I have pretty much set up everything correctly
You have selected Database to be master. Select the appropriate Database where your table exists.
In this case, select 'sqlexpress', database

I have a problem with a database hosted by Microsoft SQL Server 2008 R2.
I made a table with some varchar(length) columns.
The problem is, when I insert anything in it, it leaves "blank spaces" in the end of the column, messing everything up.
So the columns practically looks like this =
some_value _________
(__ = blanks)
Sometimes the blank spaces are even longer...
And I cannot delete them, cause even when deleting them, they get back in place.
What is it the issue?
Is the varchar(length) too high?
The fact is I cannot set it shorter, cause the value I'm going to insert in the table isn't fixed in length..
Any fix?

I have a table called programmes and an attribute called PROGRAMMES_COURSE. One of the course is engineering.
If I were to find the engineering field just by typing eng,what syntax do I use?
I have tried this but I know it's wrong
SELECT * FROM programmes WHERE PROGRAMMES_COURSE LIKE 'eng%'
SELECT *
FROM PROGRAMMES
WHERE PROGRAMMES_COURSE LIKE 'eng%'
This query should work without any problems. If it does not find what you need, you should provide more information so we can find out where the problem could be.
Try this
SELECT *
FROM PROGRAMMES
WHERE PROGRAMMES_COURSE LIKE '%eng%'

I am writing a long SQL query and I'm getting incorrect output fields. How do I debug this query?
There is no right answer to this question. I think deep down you know that.
When I have something complicated break it down to uncomplicated pieces. Once you are comfortable with these pieces then one by one start to put this complicated thing back together again. The main point is keep breaking complicated things into more and more simple things. I am not embarrassed to say I have broken things down to select sysdate from dual and then start to build back up!
Good Luck.
