Is table content the same with index?
No, table content and index are not the same. Table content refers to the actual data stored in the table, while an index is a data structure that provides a quick look-up for specific columns in the table to improve search performance.

Difference between table and index in sql?
A table is a collection of data that is organized into rows and columns. An index is a data structure that improves the performance of data fetch operations on a table. A table can exist as a standalone component but an index cannot. Indexes are built on top of tables and cannot exist without tables.

How index increase the performance of database?
Index on a table in the database is just like an index (or content page) in a book - a quick look at an index can tell you where the actual data is located. This saves time and cost of scanning the whole table, thus making the database faster.
How many indexes can be created in a table?
we can create 16 indexes 1 primary index 15 secondary indexes You should not create more than five indexes for any one table because: Whenever you change table fields that occur in the index, the index itself is also updated. The amount of data increases. The optimizer has too many chances to make mistakes by using the 'wrong' index. If you are using more than one index for a database table, ensure that they do not overlap.
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.
