/* DEMO EXAMPLES
*
* //SIMPLE SELECT
* 1. $dbObj->select() //or select('*') || select("'field1',field2") || select(array('field1','field2'))
->from($table) // pass second argument as alias
* ->fetch(); will select only one row || fetchAll () for all rows
*
*
* //SELECT WITH WHERE
* 2. $dbObj->select()
->from($table)
* ->where("field = 'value'") // or where(array('field'=>'value')) // Always put ANd between multiple condtions if array is passed
* ->fetchAll();
*
* //SELECT WITH FETCH MODE
* 3. $dbObj->select(array('field1','field2'))
->from($table)
* ->setFetchMode('FETCH_OBJ') // set fetch mode for current operation see all AVAILABLE FETCH MODES in (INTERFACE DbAdapterInterface)
* ->where(array('field'=>'value'))
* ->fetchAll();
*
* //INSERT A RECORD MANUALLY
* 4. $dbObj->insert($table,array('field'=>'field_value'));
*
* //INSERT A RECORD AUTOMATICALLY
* 5. $dbObj->insert($table,$_POST,TRUE); // THIRD ARGUMENT SET TO TRUE FOR AUTO INSERT
*
* //UPDATE A RECORD AUTOMATICALLY
* 6. $dbObj->update($table,$_POST); // IF COMPLETE FORM IS POSTED WITH HIDDEN PRIMARY KEY THEN IT WILL AUTO UPDATE
*
* 7. //UPDATE A RECORD MANUALLY
* $dbObj->update($table,array('field'=>'field_value'),array('condition'=>'value'));
*
* 8. //DELETE RECORS
* $dbObj->delete($table,array('key'=>'value'));
*
* //Query
* 9. $dbObj->query("SELECT * FROM $table")->fetch();
*
*
* //GROUP BY,ORDER BY ,LIMIT
* 10. $dbObj->select()
->from($table)
* ->orderBy('field1,field1') // or orderBy(array('field1','field2'))
->groupBy('field1') // or groupBy(array('field1','field2'))
* ->limit('1') or limit('0,10')
* ->fetchAll();
*
* //JOIN (join type,table,join conditions)
* 11. $dbObj->select(array('field1','field2'))
->from(table1,'tbl1')
->join('left','table2 as tbl2','tbl1.id = tbl2.someid')
->join('left','table3 as tbl3','tbl2.someid = tbl3.someid')
* ->fetchAll();
*
*
* 12. //OR WHERE
* $dbObj->select('*')
->from(table1,'tbl1')
* ->orWhere(array('field1'=>'value','field2'=>'value')) // Always put OR between multiple condtions if array is passed
* ->fetchAll();
*
* 13. //MIX OF ORWHERE AND WHERE
* $dbObj->select('*')
->from(table1,'tbl1')
* ->where(array('field1'=>'value','field2'=>'value'))
* ->orWhere(array('field1'=>'value','field2'=>'value')) // ALWAYS SHOULD BE USED AFTER WHERE OR STATND ALONE
* ->fetchAll();
*
* if orWhere is used with where then it will just put OR between two statement
* The syntex will create syntex below :
* SELECT * FROM {table} where (table.field1 ='value' AND table.field1 ='value' ) OR (table.field1 ='value' AND table.field1 ='value' )
*
* 14. OPERATOR USE
* (A) <> OR != :- NOT EQUAL
* (B) < :- LESS THAN
* (C) > :- GREATOR THAN
* (D) >= : GREATOR THAN EQUAL
* (E) <= : LESS THAN EQUAL
*
*
