Which of the following commands is used to create an index on a table?ACREATE INDEXBADD INDEXCMAKE INDEX
Solution
The command used to create an index on a table is A. CREATE INDEX.
Here is a step-by-step guide on how to use it:
-
First, you need to specify the name of the index after the CREATE INDEX statement. The index name should be meaningful and easy to remember.
-
Then, you specify the name of the table on which you want to create the index after the ON keyword.
-
After that, in parentheses, you specify a comma-separated list of columns on which you want to create the index.
Here is the basic syntax of the CREATE INDEX statement:
CREATE INDEX index_name ON table_name(column1, column2,...);
Please replace index_name with the name of your index, table_name with the name of your table, and column1, column2 with the names of the columns in your table.
