i am doing a computing task for as level.i am having a problem with access.actually i need little bit of description of my student id.but i know what it does but i dont know what to write...and student id is my primary key...can u tell me what student id does?????
About student id?
A primary key is a unique identifier that can be used to reference rows in the table. So if you have a table called Students, the sudentID would be a way of ensuring that you only get the exact student you want in your query. For example, "SELECT * FROM Students WHERE StudentID = '123'" would return just the information for that one student.
Other than that, your question was WAY too vague to give a more meaningful answer, and you left us to assume a lot. Add some more description and we might be able to help.
