Entities and Objects: Description of Objects: Table: Index

For technical specifications on the indices of a table, see the official documentation of PostgreSQL.

The window shown in the figures below, lets you change the properties of an index of a table.

As with all objects in a project, the area has a window where you must enter the name of the object, unique within the table. In addition to the name, the window contains all the properties of the field.

Changing a table index is accessible only by editing window table.

The combo "Tablespace" contains a list of all objects tablespace in the project. By selecting one, it is hooked to it is in any case impossible not to assign a specific tablespace, in this case, the index will be assigned to the tablespace default PostgreSQL.

For the composition of index fields, there are two lists: the list on the left contains a list of all the fields in the table, while the list on the right lists all fields included in the index. Through the two buttons positioned between the two lists you can add or delete a field in the index ( "+" adds, "-" delete ).

Note: Changes made on the indices are not annulled if you cancel the changes made in the editing of the table.
