OLE DB 1.5 as originally released is Compliant#. A description of the issues is given below.
Updated versions of OLE DB (with the correction bringing it to full compliance) are being made available through
Microsoft Data Access Components (MDAC) 2.0 Service Pack 1, which shipped with Windows NT4 Service Pack 4
Microsoft Data Access Components (MDAC) 2.1
See Note 2 below for more information.
How the product handles dates:
The five OLE DB data types that store date-time information are DBTYPE_DATE, DBTYPE_DBTIME, DBTYPE_DBTIMESTAMP, DBTYPE_DBDATE, and DBTYPE_FILETIME.
Of these, DBTYPE_DBTIME does not store date information. The other four data types store the date information compatible with a longhand 4-year digit convention. Therefore, the date issues are the conversions involving strings.
DBTYPE_DBTIMESTAMP, DBTYPE_DBDATE, and DBTYPE_DBTIMESTAMP string conversions are based on ISO. However, they will also accept OLE Automation date formats, including dates with 2-digit year shortcuts.
Two-digit shortcut handling:
OLE DB uses the standard OLEAUT solution that interprets 00-29 as 20XX and 30-99 as 19XX.
Common date usage errors:
Always use 4-digit year when storing data or calling methods/properties of any of the MDAC data access APIs. Using 2-digit years may reveal year-windowing in your backend or provider, where the boundary cases may not be well known (given an arbitrary backend data store).
Testing guidelines and recommendations:
Since there is some "windowing" inherent in the date features of most backend data stores, users should use 4-digit year formats in dates, particularly when placing data into a store and querying that store.
Known issues:
The known Year 2000 issues for OLE DB data coercion library are:
If you code to ADO,
AND your ADO Recordset includes Date data types, such as: adDate, adDBDate, adFileTime, or adDBTimeStamp.
AND you're using a date format in which periods are used instead of slashes for date separator (01.01.98 instead of 01/01/98)
AND you specify a year less than 60,
THEN Data Convert (msdadc.dll) may translate your date as a time. For example, 01.01.01 (January 1t, 2001) could be converted to 01:01:01 (December 30, 1899, 1:01:01am).
OR,
If you code directly to OLE DB, the same case exists:
If you're converting from a variant (BSTR, VARIANT or PROPVARIANT) to date datatypes, such as:
DBTYPE_DATE
DBTYPE_DBDATE
DBTYPE_DBTIME
DBTYPE_FILETIME
DBTYPE_DBTIMESTAMP
AND you're using a date format in which periods are used instead of slashes for date separator (01.01.98 instead of 01/01/98)
AND you specify a year less than 60,
THEN Data Convert (msdadc.dll) may translate your date as a time. For example, 01.01.01 (January 1, 2001) could be converted to 01:01:01 (December 30, 1899, 1:01:01am).
NOTE 1:
If you're coding directly to OLE DB, and youÆre converting a Variant BSTR to DBDATE, the date "0001-01-01" may be interpreted as "2001-01-01". This issue only affects the years 0001 to 0099. For this reason, the operational range should be considered to start no lower than year 0100.
NOTE 2:
To distinguish a compliant version of OLE DB from one thatÆs Compliant#:
1) check the version of the DLL pointed to by this registry key:
HKEY_CLASSES_ROOT\CLSID\{c8b522d1-5cf3-11ce-ade5-00aa0044773d}\InprocServer32\(default)
2) OLE DB is Compliant# if the version is
greater than 1.50.0000 and less than 1.50.9801, or
greater than 2.0.0000.00 and less than 2.0.3002.23,
OLE DB is compliant if the version is
greater than or equal to 1.50.9801 and less than 2.0.0000.00, or
greater than or equal to 2.0.3002.23, or
greater than or equal to 2.10.0000.00
