SQL Combining two joins -

i understanding of sql average, wondering if there way more efficiently write statement?

the primary key of table company uniqentity , has company name nameof in row.

in table line, primary key uniqline , have columns entitycompanybilling , entitycompanyissuing (both foreign keys uniqentity).

this code below works fine, trying make more efficient. possible?

select     l.uniqline, b.nameof billingcompany,     l.uniqentitycompanybilling, i.nameof issuingcompany,     l.uniqentitycompanyissuing     line l  inner join     company b on b.uniqentity = l.uniqentitycompanybilling inner join     company on i.uniqentity = l.uniqentitycompanyissuing  

changing structure of query may not make more efficient (it seems simple can be). changing structure of data might:

• add indexes (if not already) on uniqentitycompanybilling , uniqentitycompanyissuing
• add index on company.uniqentity ^{didn't catch column pk}
• if index on company.uniqentity isn't clustered, include nameof field in index on company.uniqentity query doesn't have go physical table.
