This document provides an introduction and overview of C# programming and SQL. It discusses key aspects of C#, its uses in Windows, web, and web service applications. It also covers SQL fundamentals like retrieving, inserting, updating, and deleting records. The document includes examples of SQL statements like INSERT, UPDATE, DELETE, and SELECT and highlights best practices like enclosing string values in single quotes and ending statements with semicolons.

2. Hello World – A quick glance of this
tutorial
• Introduction to C#.net
• Introduction to SQL
• The OLEDB Library
• Setting up your connection string
• Creating the connection Class
• Create Read Update Delete
(CRUD)

3. What’s with C#
• The Language of choice in the
.NET Framework
• Comes with a clear syntax, derived
from C/C++
• Ease with learning the language
• C# is a “Type Safe Language”

4. What can you do with C#
• Windows Applications
• Web Applications (ASP.NET)
• Web Services (WCF)

5. Structured Query Language (SQL)
• A language use for manipulating
and retrieving records in a RDBMS
• Based on Relational Algebra tuple
relational calculus, its scope
includes data insert, query, update
and delete, schema creation and
modification, and data access
control.

6. Adding Records to your Table
INSERT INTO
table_name(column1,column2)
VALUES(value1,value2);
Specifying the columns and
corresponding values on
those columns.

7. Adding Records Cont..
INSERT INTO table_name
VALUES(value1,value2,..valueN);
Use for adding records
provided that the number of
values match the number of
columns

8. Sample INSERT INTO
Statement
Let’s assume we have table
phonebook with 3 columns,
FirstName, LastName, and
PhoneNumber
INSERT INTO phonebook
VALUES(‘jm’,’ramos’,’123’);

9. Modifyng Records
UPDATE table_name SET
column1 = value1, column2 =
value2 WHERE id = my_id;
Updates the record that has
the id of my_id;

10. Sample UPDATE Statement
UPDATE Phonebook SET
PhoneNumber = ‘09099234556’
WHERE FirstName = ‘jm’;
Updates all records that
has a firstname of ‘jm’

11. Deleting Records
DELETE FROM table_name
WHERE id = my_id;
Deletes the record the has
the id = my_id. If the user
fails to put a where
condition, all records from
the table will be lost.

12. Retrieving Records
SELECT (column1, column2)
FROM table_name WHERE id =
my_id;
Returns a result set
containing columns
specified in the query
satisfying the condition
Where clause is optional

13. Enough with the Crap. Coding na!
• :DDDDD

14. Things to Remember:
• String data types in SQL should be
enclosed with single quotes.
• Values are separated by commas
• End every statement with
Semicolon
• Just get what you need.
• Use pascal casing.
