5. Retrieving Data Using the SQL SELECT Statement
Understand Operator Precedence
Precedence defines the order that Oracle uses when evaluating different operators in the same expression. Every operator has a predefined precedence. Oracle evaluates operators with a higher precedence before it evaluates operators with a lower precedence. Operators with equal precedence will be evaluated from left to right
MySQL - Query

6. Restricting and Sorting Data
Write queries that contain a WHERE clause to limit the output retrieved
Syntax : Select <Column Name,……Column Name>
From <Table Name>
Where <Column Name or Logical Phrase>;
Sample : SELECT item_id, item_name, item_uom
FROM ti3k_item_master
Where item_uom ='Set';
Write queries that contain an ORDER BY clause sort the output of a SELECT statement (Ascending or Descending)
Sample : Select * from ti3k_item_master
Order by item_uom asc;
Order by item_id desc;

7. Restricting and Sorting Data
List the comparison operators and logical operators that are used in a WHERE clause
MySQL - Query

8. Sample SELECT with WHERE using Comparison operators
Exercise:
select item_uom “UOM” from ti3k_item_master
where item_code =‘DRL10’;
select item_id, item_code, item_name, item_uom, remark
From ti3k_item_master
where item_id > 50
And item_uom =‘Each’;
select * from ti3k_item_master
where item_uom in (‘Sax’,’Set’)
Order by item_uom, item_id;
where remark is null
Or created_by = ‘Salim’;
where item_id between 10 and 20;
