-- Example for SQL DATETIME2FROMPARTS Function SELECT DATETIME2FROMPARTS ( 2017, 12, 18, 15, 45, 09, 5, 1 ) AS Result SELECT DATETIME2FROMPARTS ( 2017, 12, 18, 15, 45, 09, 50, 2 ) AS Result SELECT DATETIME2FROMPARTS ( 2017, 12, 18, 15, 45, 09, 503, 3 ) AS Result -- Let me try the NULL values SELECT DATETIME2FROMPARTS ( 2017, 12, NULL, 15, 45, 09, 503, 3 ) AS Result -- Precision Value is greater than Fraction SELECT DATETIME2FROMPARTS ( 2017, 12, 18, 15, 45, 09, 503, 7 ) AS Result -- Precision Value is Les than Fraction. Invalid argument SELECT DATETIME2FROMPARTS ( 2017, 12, 18, 15, 45, 09, 503, 2 ) AS Result |
