What does a sort mean in a database?
Sort refers to the action wherein the data fetched from a database table is ordered as per a specific criteria. The default order of sort is Ascending and the user can do a descending sort by using the keyword DESC after the order by keyword. Ex: select * from employee_details order by employee_num desc If the above statement is executed data will be displayed in descending order of employee numbers.

How can you sort the results from an sql statement?
You can sort the results of a query by using the order by clause. Ex: Select * from tbl_employee order by emp_num The above query would sort the results by the employee number and display them. The default sort is ascending order. Ex: Select * from tbl_employee order by emp_num desc The above query would sort the results by descending order of employee number and display them.

Advantages of using indexes in database?
Advantages of an index over no indexIf no index exists on a table, a table scan must be performed for each table referenced in a database query. The larger the table, the longer a table scan takes because a table scan requires each table row to be accessed sequentially. Although a table scan might be more efficient for a complex query that requires most of the rows in a table, for a query that returns only some table rows an index scan can access table rows more efficiently.The optimizer chooses an index scan if the index columns are referenced in the SELECT statement and if the optimizer estimates that an index scan will be faster than a table scan. Index files generally are smaller and require less time to read than an entire table, particularly as tables grow larger. In addition, the entire index may not need to be scanned. The predicates that are applied to the index reduce the number of rows to be read from the data pages.7 If an ordering requirement on the output can be 7 matched with an index column, then scanning the index in column order will 7 allow the rows to be retrieved in the correct order without a sort.Each index entry contains a search-key value and a pointer to the row containing that value. If you specify the ALLOW REVERSE SCANS parameter in the CREATE INDEX statement, the values can be searched in both ascending and descending order. It is therefore possible to bracket the search, given the right predicate. An index can also be used to obtain rows in an ordered sequence, eliminating the need for the database manager to sort the rows after they are read from the table.In addition to the search-key value and row pointer, an index can contain include columns, which are non-indexed columns in the indexed row. Such columns might make it possible for the optimizer to get required information only from the index, without accessing the table itself.Note:The existence of an index on the table being queried does not guarantee an ordered result set. Only an ORDER BY clause ensures the order of a result set.

How do you describe Sort in a field of Microsoft Access?
Sorting is putting things in order, like in date order or numerical order of alphabetical order. It can be in either order, like lowest to highest or highest to lowest. In Access, you can choose to sort a table on one or more fields. You can also choose to sort any listing of data, like the results of a query or a report.Sorting is putting things in order, like in date order or numerical order of alphabetical order.

What does it mean to sort a table in ascending order?
To sort from smallest to largest. Ascending means to go up.
Can you sort a table without a primary key?
Yes. You can sort on any attribute or combination of attributes in a table (in SQL using the "order by" clause). Of course the sort is only as good as the "uniqueness" of the attribute you sort on, hence a combination of attributes may be helpful. A primary key is, by definition, unique across all rows in the table.

Can you sort more than one column at a time using Excel?
No, you can sort multiple columns or rows if you hightlight a range, but all columns or rows will need to be sorted with the same criteria (e.g. lowest to highest). You can sort an entire row by clicking on the row number at the left of the screen, then sort, as desired. You also can do the same for columns by clicking on the column letter at the top of the screen.

In access to order the records in the answer to a query in a particular way you what the records?
I took the same quiz. The answer is "sort" (I got it wrong because I said arrange [serioussly this is rediculous!])
How do you sort data in a table?
Use the Sort option. You can then choose which columns or fields to sort on.
When sorting a Excel worksheet can you sort multiple columns within the same sort?
You can sort multiple columns, based on one or more column. The first selected column is the one that determines the sort order when you have multiple columns selected. You can also sort using multiple columns to determine the sort, like sorting surnames, and within that, sorting people who have the same surname by firstname. All of this can be done through the sort options, rather than just clicking on the icon to do a simple sort.You can sort multiple columns, based on one or more column.

When you sort data in a query the records in the underlying table are actually rearranged?
No. Most queries list off data, but does not affect the underlying data. Certain types of query can be used to change data in a table, but do not re-arrange the order of the data in the table itself. That is determined by the indexes, mainly the primary key. You can sort the data in the table itself and have it remain that way.
