This is a function of the MSSQL database, the function of the CONVERT function is to convert the data type. and the Convert (char (), opendate,120) You're asking is a function that formats the date field and converts it into character formatting.

syntax structure:
1. Cast
Syntax structure: CAST (expression as data_type [(length)])
2. Convert
Syntax structure: CONVERT (data_type [(length)], expression [, style])
3. Parse
Syntax structure: PARSE (string_value as data_type [USING culture])
Where Parse is a new feature of SQL Server expression must be a string form of the converted Type

Summarize:
1. The difference between
