Access Database And Using A Parameter Query With The LIKE Operator To Return All Rows That Match Query?
Apr 28, 2010I am connecting to an Access database and using a parameter query with the LIKE operator to return all rows that match query. The string to search for is taken from a Textbox

SQL Query To Ms Access 2003?
Jun 16, 2011i have a database in access 2003 and i submit a query to a specific table. The fields of this specific table (STOCK_PRICES1) :
DATE --> type date (d:M:yyyy)
CODE --> type text
OPEN --> type single
HIGH --> type single
LOW --> type single

i receive an error. Why? Conflicts between access 2003 and vb.net 2010? SQL Server is better?And another question. My Regional settings regarding the date is d/M/yyyy but in my vb.net example, the @date1, @date2 parameters accept M/d/yyyy dates. Is there a way to define into the parameters the d/M/yyyy specification?

Filling A Datagridview With An Access Query ?
Aug 25, 2009I have an access query which plays flawlesly in Access.I want to use it as a source for a datagridview i use in one of my forms but....given the fact that is a rather big query with some "like" and conditions like ">3" and so on AND the fact it uses tables from 3 different mdb (not to mention is bases on other queries...i 'ill try my best to fix this) what is the best approach .
1st case .Can i retrieve the data simply with NO oledbparameteres and NO " select * xxx where yyy like 'd' ".I think there is a issue with the Oledb connection that "omits" them.To explain better the query right now with the filters in access returns 3 rows, without the filters 30 rows,can i get just the 3 rows to do my job... 2nd case . How should i fill a datagridview using tables from 3 different mdbs.If you can show me an example it would be life saving.
How Does One Add A Query To An Access 2007 Database
Jun 22, 2010I have an application that uses an *.accdb file as the back-end database. Connecting to and retrieving data from the access file is not an issue and is working quite well. However, as a precaution, I have the application first check to make sure the database file exists in the application's folder while it loads up. As a convenience, if the database file is not found, then the application creates a new (structured, yet empty) database. The creation of the actual *.accdb file and the creation of the tables is complete and is also working well.
