How does timestamp work in sql

For complete information regarding syntax and additional examples, see the description of the CAST function. In some cases, this syntax can be deceiving. For example, a value such as '' might look like a time value because of the : , but is interpreted as the year '' if used in date context. The value '' is converted to '' because '45' is not a valid month. The only delimiter recognized between a date and time part and a fractional seconds part is the decimal point. The server requires that month and day values be valid, and not merely in the range 1 to 12 and 1 to 31, respectively.

With strict mode disabled, invalid dates such as '' are converted to '' and a warning is generated. With strict mode enabled, invalid dates generate an error. See Section 5.

Timestamp I agree as it shows a hexadecimal value like 0xD9 which simply increments by 1 whenever I make any update in the row. Then why are you saying that both formats are not capable of storing date and time. This counter is the database rowversion. This tracks a relative time within a database, not an actual time that can be associated with a clock.

A table can have only one rowversion column. Every time that a row with a rowversion column is modified or inserted, the incremented database rowversion value is inserted in the rowversion column.
