how to retive datafrom the table?

Sea · Accepted Answer

This is the example to retreive information from database for a table.

Here [('user_id', '=', uid)] --> Here we can include the condition we put in WHERE clause

emp_obj = self.pool.get('hr.employee')
emp_ids = emp_obj.search(cr, uid, [('user_id', '=', uid)], context=context)
if emp_ids:
for employee in emp_obj.browse(cr, uid, emp_ids, context=context):
return {'name': employee.name}

--->Hope this helps you

It is recomandable to use object model to read data from the database, however some times it is more efficient to read data with SQL. If you want to read data with direct SQL, you can use the cr (cursor) that is passed to your methods as follows:

cr.execute(""" SELECT name FROM res_partner""")
result = cr.fetchall()
for partner in result:
print partner[0]

/ cr.execute(""" SELECT name FROM res_partner""") /
/result = cr.fetchall()
for partner in result:
print partner[0]/
