Hi guys,

I am learning to use OLE2 now in PL/SQL and I encountered some strange occurances while loading the data from Excel file into the database.

In some of the column, like 'Date' and 'Quantity'; whenever I load the excel file data into the database, there is a discrepancy between data loaded to the database and those of in Excel file.

E.g: (data in excel)

Date Qty
-------- ---------------- ===> field is formatted into
20081205 100000 general format.

(data in database)

Date Qty
------- -------- ====> (both are varchar2 datatype)
2 1

this problem is solved by using get_num_propety and then convert it to varchar datatype....

My question is, why is there a discrepancy in the data (in database and excel file) and I had used get_num_property instead of get_char_property? why can't the data in excel treated as varchar implicitly? Is there any other method to get the data correctly withouth having to covert from number and to char?


Sorry for the trouble again, especially christmas is near... Embarassed
