SQL Server Index Naming Conventions

Is there some standard way to name indexes for SQL Server? It seems that the primary key index is named PK_<tablename> and non-clustered indexes typically start with IX_<tablename>. Are there any naming conventions beyond that for unique indexes?

I usually name indexes by the name of the table and the columns they contain:

ix_tablename_col1_col2

I use

PK_ for primary keys

UK_ for unique keys

IX_ for non clustered non unique indexes

UX_ for unique indexes

All of my index name take the form of
`<index or key type>_<table name>_<column 1>_<column 2>_<column n>`

I know a old topic but thought I'd throw in my 2cents worth

- PKC_ Primary Key, Clustered
- PKNC_ Primary Key, Non Clusterd
- NCAK_ Non Clustered, Unique
- CAK_ Clustered, Unique
- NC_ Non Clustered


Example;

NCAK_AccountHeader_OrganisationID_NextDate

Where NCAK : Non Clustered, Unique, AccountHeader : Table and OrganisationID_NextDate : Columns.

Is it worth a special prefix for indices associated with foreign keys? I think so, since it reminds me that indices on foreign keys are not created by default, and so it is easier to see if they are missing.

For this, I am using names that match the name of the foreign key:

FK_[table]_[foreign_key_table]

or, where multiple foreign keys exist on the same table

FK_[table]_[foreign_key_table]_[foreign_key_field]
