Creating a Sybase composite index

Tech Computer Center logo

Use a composite index when two columns are logically connected, such as a city and a zip code. They can not be created on text or image datatypes.

At the end of each command press the space-bar or press enter before continuing the next step.

  1. To create a composite index, type
            create index
  2. Type the name for the index.
  3. Type
  4. Type the name of the table you are creating an index on.
  5. Since composite indexes use more than one column, you need to group them in parenthesis and separate the columns by a comma. Type
  6. Type the first column name you want to create the index on.
  7. For each subsequent column you want to include in the index, type a comma, then the column name.
  8. Type
  9. Type
  10. Press Enter.

If everything goes well, you see the database prompt (a period, the name of the database you are using, another period, the number one and then the greater than symbol).
