5. 1. Which TCP/IP port does SQL Server run on? How can it be changed?
SQL Server runs on port 1433. It can be changed from the Network
Utility TCP/IP properties.
2. How to generate row number in SQL Without ROWNUM
Generating a row number – that is a running sequence of numbers for
each row is not easy using plain SQL. In fact, the method I am going to
show below is not very generic either. This method only works if there is
at least one unique column in the table. This method will also work if
there is no single unique column, but collection of columns that is
unique
SELECT name, sal, (SELECT COUNT(*) FROM EMPLOYEE i WHERE o.name
>= i.name) row_num
FROM EMPLOYEE o
order by row_num
3. What are the difference between clustered and a non-clustered index?
I. A clustered index is a special type of index that reorders the way
records in the table are physically stored. Therefore table can have
only one clustered index. The leaf nodes of a clustered index contain
the data pages.

6. II. A non clustered index is a special type of index in which the
logical order of the index does not match the physical stored order of the
rows on disk. The leaf node of a non clustered index does not consist of
the data pages. Instead, the leaf nodes contain index rows.
4. What are the different index configurations a table can have?
1. A table can have one of these index configurations:
2. No indexes
3. A clustered index
4. A clustered and many non clustered indexes
5. A non clustered index
6. Many non clustered indexes
5. What are different types of Collation ?
Sensitivity?
1. Case sensitivity - A and a, B and b, etc.
2. Accent sensitivity
3. Kana Sensitivity - When Japanese kana characters Hiragana and
Katakana are treated differently, it is called Kana sensitive.
4. Width sensitivity - A single-byte character (half-width) and the same
character represented as a double-byte character (full-width) are
treated differently than it is width sensitive.

7. 6. What is OLTP (Online Transaction Processing)?
In OLTP - online transaction processing systems relational database design
use the discipline of data modeling and generally follow the Codd rules of
data normalization in order to ensure absolute data integrity. Using these
rules complex information is broken down into its most simple structures (a
table) where all of the individual atomic level elements relate to each other
and satisfy the normalization rules.
7. What's the difference between a primary key and a unique key?
Both primary key and unique key enforces uniqueness of the column on
which they are defined. But by default primary key creates a clustered index
on the column, where are unique creates a nonclustered index by default.
Another major difference is that, primary key doesn't allow NULLs, but
unique key allows one NULL only.
8. What is the difference between a Local and a Global temporary table?
A local temporary table exists only for the duration of a connection or, if
defined inside a compound statement, for the duration of the compound
statement.
A global temporary table remains in the database permanently, but the rows
exist only within a given connection. When connection is closed, the data in
the global temporary table disappears. However, the table definition
remains with the database for access when database is opened next time.

8. 9. What is the STUFF function and how does it differ from the REPLACE
function?
STUFF function is used to overwrite existing characters. Using this syntax,
STUFF (string_expression, start, length, replacement_characters),
string_expression is the string that will have characters substituted, start is
the starting position, length is the number of characters in the string that
are substituted, and replacement_characters are the new characters
interjected into the string. REPLACE function to replace existing characters
of all occurrences. Using the syntax REPLACE (string_expression,
search_string, replacement_string), where every incidence of search_string
found in the string_expression will be replaced with replacement_string.

9. 10. What is PRIMARY KEY?
A PRIMARY KEY constraint is a unique identifier for a row within a
database table. Every table should have a primary key constraint to
uniquely identify each row and only one primary key constraint can be
created for each table. The primary key constraints are used to enforce
entity integrity.

10. 11. What is UNIQUE KEY constraint?
A UNIQUE constraint enforces the uniqueness of the values in a set of
columns, so no duplicate values are entered. The unique key constraints
are used to enforce entity integrity as the primary key constraints.
12. What is FOREIGN KEY?
A FOREIGN KEY constraint prevents any actions that would destroy links
between tables with the corresponding data values. A foreign key in one
table points to a primary key in another table. Foreign keys prevent
actions that would leave rows with foreign key values when there are no
primary keys with that value. The foreign key constraints are used to
enforce referential integrity.
13. What is CHECK Constraint?
A CHECK constraint is used to limit
the values that can be placed in a column. The
check constraints are used to enforce domain integrity.
14. Error severity 13 indicates what?
Transactional deadlock errors.
This level of error severity indicates a transaction
deadlock error.
