Question

Do index names have to be unique accross the entire sql server database, or just for that table?

For example, should I name my index: IX_OrderLoadCarrierDelivery_OrderLoadID

for the OrderLoadID column of the OrderLoadCarrierDelivery table. Or should I just name it IX_OrderLoadID

Answer 1

They have to be unique for the table or view they were created for.

Here is a reference on Microsoft Learn that details this.

FTA:

index_name

The name of the index. Index names must be unique within a table or view, but don’t have to be unique within a database. Index names must follow the rules of identifiers.

I believe the convention is:

IX_FieldName
