General - Do you use a SQL Server Indexes Naming Standard?

Last updated by Tiago Ara├║jo [SSW] on 05 Jul 2021 10:46 pm (5 months ago) See History

This standard outlines the procedure on naming Indexes at SSW for SQL Server. Use this standard when creating new Indexes or if you find an older Index that doesn't follow that standard.

Note: There is not a lot of use naming Indexes - we only do it when we are printing out documentation or using the 'Index Tuning Wizard' - then it becomes really handy.

Index names are to have this syntax:

[pkc_] [TableName] by [FieldName]
[1] [2] [3]

[1] All indexes must have a corresponding prefix.

Prefix Type
pkc_ Primary Key, Clustered
pknc_ Primary Key, Non Clustered
ncu_ Non Clustered, Unique
cu_ Clustered, Unique
nc_ Non Clustered (Most Common)

Make unique index name if possible. Ie. ProductName

[2] The name of the table that the Index refers to. [3] The name of the column(s) that the Index refers to.

Index 'BillingID'
Primary Key 'aaaaaClient\_PK'

Figure: Bad Example

'nc\_ClientDiary\_BillingID'
'pknc\_ClientDiary\_ClientID'

Figure: Good Example
