Databases :: Type Mismatch In Criteria Expression?
Jan 9, 2011
I am importing data from an Excel worksheet. The columns are labelled aa, ab, ac .... in row1 and the rows are labelled with integers in col aa. Although I can import the entire worksheet (so long as it isn't too big), when I add a WHERE clause to import only a single row I get a type mismatch which I have not been able to isolate. How can I make progress.

I am validating user from Login.xlsx file. It was working fine by validating email and password from that file. For testing i got new file same contents of file but added some more user names. So after that when i validating the user i am getting the following error "Data type mismatch in criteria expression".
But when i replaced the new to old one it is working fine. The contens of both files are the same. So why this kind of error happened.

I'm trying to make a search that would list results in an access database which is newer than the date given in the textbox. When i run my sql query and it tries to fill the dataset, i get that data type mismatch error. This is the exact error:

In the access database the date field is of datetime type. The dates are in european DD.MM.YYYY format which i transform using datetime variable and convert function. The sql query runs fine in access database but when i run it thru my oledb connection in my asp.net page it gives me errors. How should i modify my query, or make adjustments to my code, to not get this error? Do i need to send the datetime as a parameter? And how do i do that? Here is the code for the search event:

The error come out only when it is hosted on the web server where IBM Informix Connect 2.81 is installed.
I have gone through many articles and it suggest me to set the environement variable in the server : DB_LOCALE=en_us.819.
I haven't try this solution but i think that this might not be the best solution.
Is it possible to to to have this setting in the web application ?Does anyone has idea on this?Is it true that there is no other solution than setting the environemetn variable DB_LOCALE?

I have a Excel user application which has a user form (named 'Registo') that displays criteria and an image that has been entered in it's corresponding spreadsheet. This works the way it should. There's also the ability to search the spreadsheet via a form (by clicking 'Pesquisar' button) this opens a search form. However, I having a bit of a problem with it. When I try to search for something it basically doesn't do anything at all. It just sits there. So I tried to debug it and I think I'm having a problem with either the JET db engine or somethign with teh query or maybe I don't have the correct reference.
For the life of me, I can't figure out what the problem is with this:
