SQL SERVER: What is the difference between PARSE, FORMAT, and CONVERT? -


i trying understand idiosyncrasies , appropriate uses of parse vs. format vs. convert in sql server 2014.

parse

parse ( string_value data_type [ using culture ] )

format

format ( value, format, [ culture ] )

convert

convert(data_type(length),expression,style)

seems similar, different order of required arguments. , different format of arguments (e.g. convert uses style codes while parse uses culture codes).

parse , format added sql 2012 more precise parsing , string formatting.

parse , format opposite operations (parse converts string type; format converts non-string type string using specific format (e.g. currency, date-time).

convert limited conversions in either direction. still exists backwards-compatibility.
