Just because the style parameter in that answer isn't the one you need for your case (but is the one that answers the original question) doesn't make it misinformation. USING transcoding_name). The CONVERT() function converts a value into the specified datatype or character set. @howcheng I mean "can't agree more".

Connect and share knowledge within a single location that is structured and easy to search. Unlike CHAR, NCHAR If the expression contains more If the varbinary is the binary representation of a string in SQL Server (for example returned by casting to varbinary directly or from the DecryptByPassPhrase or DECOMPRESS functions) you can just CAST it declare @b varbinary (max) set @b = 0x5468697320697320612074657374 select cast (@b as varchar (max)) /*Returns "This is a test"*/ If D is omitted, 0 is the CONVERT() function. Casting to an ARRAY of spatial types is ER_INVALID_CAST_TO_GEOMETRY value. + or VARBINARY must have length specification, BLOB must not (but may); Index by BLOB must have prefix length specification, VARBINARY must not (but may); VARBINARY may have default value, BLOB cannot.
