SQL Server Index Entire Table Guide
To add an index to a table, you can use the following SQL statement:
CREATE INDEX index_name ON table_name (column1, column2, ...);
Where index_name refers to the name of the index, table_name is the name of the table where the index will be added, and column1, column2, … represent the column names where the index will be added.
To add indexes to all columns in a table, you can use the following SQL statement:
CREATE INDEX index_name ON table_name (*);
Note: Adding an index may impact performance, so it is important to carefully consider before adding an index and select the appropriate column based on the actual situation.
