📝 SQL Server Note: FORMAT() vs CONVERT() Which is more optimize for Date Conversion? - FORMAT(trans_date, 'yyyy-MM') - CONVERT(char(7), trans_date, 126) 💡 FORMAT = Fancy but Slow Think: FORMAT = F = Fancy formatting + Full table scans + For reports only ❎ Use FORMAT() only when: Small datasets, Pretty formatting for reporting, Performance is not critical 💡 CONVERT = Classic + Fast Think: CONVERT = C = Classic, Clean, and Considerably faster ✅ Use CONVERT() for: 1. Production queries 2. Large datasets 3. Anything performance-critical 4. Cases where indexes matter “FORMAT is for humans ,CONVERT is for databases.” #AIDataEngineer #SQL #Databases #Technology #BigData #Learning #innovation
