Q:

What is the use of FOR XML in SQL Server?

Answer

SQL Server is having a fantastic feature to retrieve data persisted in the form of XML format. The data in the XML format can be retrieved using FOR XML clause appending to the SELECT statement.


It offers 3 modes.


- “FOR XML AUTO": Returns XML elements that are nested, based on which tables are listed in the "from" part of the query, and which fields are listed in the "select" part.


- "FOR XML RAW": Returns XML elements with the "row" prefix (ex: ""). Each column in a table is represented as an attribute and null column values aren't included.


- "FOR XML EXPLICIT": Explicit mode is the most complex shaping method used in SQL Server 2000. It allows users to query a data source in such a way that the names and values of the returned XML are specified before the query batch is executed.

Q:

What are Cursors? Explain Types of cursors in PL/SQL

Answer

Cursors help you manipulate the information retrieved by select statements. This can be done by assigning a name to the cursor.


Example:


CURSOR emp_cur 


IS 


SELECT emp_number from employee_tbl where employee_name = name_in;


Types of Cursors:


Implicit cursors- These cursors are not declared by the programmer. They are issued when the SQL statement is executed. The open, close and fetching is done by itself.


Example:


UPDATE employee SET salary = salary * 2.1;


Here, an implicit cursor is issued to identify the set of rows in the table which would be affected by the update.


 


Explicit cursors- These cursors are defined by programmer. They are used in queries that return multiple rows.


Example:


CURSOR emp_cur 


IS 


SELECT emp_number from employee_tbl where employee_name = name_in;
