问题
I want to copy elements to a remote MS-SQL database. I got conversion error on it.
When I checked the ADOTable structure I saw the MS field
WHENCREATED DATE [NULL]
is converted to
ftWideString 10
Hmmmmm....
Is it normal? Or I can set something to Date fields are come as TDateTime?
The Provider is "SQLOLEDB.1"
回答1:
Its a DATE (yyyy-mm-dd) type which was introduced in SQL Server 2008 as an alternative to the DATETIME type.
Because SQLOLEDB.1 precedes this there is a backward conversion to DBTYPE_WSTR, using an updated provider (SQLNCLI) would be preferable.
