I know that in MySQL
we can quote identifiers with back tick symbol, whereas in Oracle
(and other RDBMS that follow standard) we can use double quotes around table names and field names. I wonder whether it somehow improves security and should we use this technique in real world applications in parallel with traditional methods like preparation of sql statements?

Is there a Max function in SQL Server that takes two values like Math.Max in .NET?
I want to write a query like this:

function works, right? It is an aggregate function so it expects a single parameter and then returns the MAX of all rows.
Does anyone know how to do it my way?

MySQL should I ever use USE INDEX and when?
I came across suggestion that I should never use "USE INDEX" to tell MySQL which index to use. An expert said I should leave the decision to optimizer. That probably means I should just create indexes on columns that are most needed and not worry about it anymore. It would be really good if I can do that and rely on optimizer.
What do you think about that? Any pitfalls?
Efficient way to dedupe Hive table?

SQL: Conditional Insert/Update
Hi I am working with a table like the one below in SAP HANA:
Outcome Value Rating
Yes 0 null

I need to populate the Rating column conditionally so that if:

Value < -15; Rating = 'Low"
Is there anyway I can do this using an INSERT or UPDATE statement?

How would I use ON DUPLICATE KEY UPDATE in my CodeIgniter model?
I have a CodeIgniter/PHP Model and I want to insert some data into the database.
However, I have this set in my 'raw' SQL query:
ON DUPLICATE KEY UPDATE duplicate=duplicate+1
I am using CodeIgniter and am converting all my previous in-controller SQL queries to ActiveRecord. Is there any way to do this from within the ActiveRecord-based model?
Thanks!

Is it good practice to have individual database for testing an application for each developer
My company has decided that each developer should have its own database locally for testing the Asp.net web application. I am against the decision as I think there should be a centralised test database for testing. But the developers put an argument that if they test the same table and other developers delete the records while I add the records at the same time it will create incorrect result. So what you guys think.

Course course = new Course();

Is there any functions within SQL Server or Report builder that can accommodate this or am I going to have to have a web based solution for this?

how mysql deal with different type convert when using where clause
for example there is a type varchar(50) named by cardNo in table "bankcard",and it has a record,value is 6228480329288486759 when i query it as follows
SELECT id,cardNo FROM BANKCARD WHERE cardNo = 6228480329288486000
it will find the record "6228480329288486759"
however,use clause like this
SELECT id,cardNo FROM BANKCARD WHERE cardNo = "6228480329288486000"
the result dose not exist
i wonder how mysql deal with the the different type,convert numeric type to varchar
How can I store a dictionary in an Azure SQL Database? (Swift)
I want to store a dictionary in a column in an Azure SQL Database. I've tried to store a dictionary by doing :
let item = ["text":["foo":"bar"]]
let itemTable = client.tableWithName("TodoItem")
itemTable.insert(item) {
(insertedItem, error) in
if (error != nil) {
print("Error" + error!.description);
} else {
print("Item: " String(insertedItem!))
}
}
But when I query the database I get
Item: [Object object]
How can I store and query dictionaries in the database without the items changing?
