I 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 =
"Select * FROM Allview WHERE Info Like" &
"*" &
CStr(TextBox1.Text) &
"*"
The query does not return any data in vb, but when run from access with same string, there is data returned.The connection to the database is done correctly, as I am able to return data with various other queries.

I am trying to run a query an Access db from VB. The general query which I want to run is
SELECT * FROM Patient WHERE Patient.PatientID = ?
or SELECT * FROM Patient WHERE Patient.PatientLname = ?

Then I read about writing a function and using that, however, I keep getting an error which says Function not defined, but when stepping through the code, it seems to work.

View 2 RepliesI have taken over support of a VB .Net application that makes use of an Access database. Now I discover that the developer who wrote this application did not create any unique indexes on the primary key columns for the tables in the database. So none of the primary key fields are actually flagged as being primary keys in access and so no duplicate checking is being performed by Access. Furthermore, the primary key columns are not being auto-incremented with an AutoNumber type in Access, rather the developer has used queries like this to insert rows into the tables:
INSERT INTO Users (pkid, FirstName, Surname, City)SELECT iif(isnull(max(pkid)),0,max(pkid))+1, [@strFirstName], [@strSurname], [@strCity], FROM Users;This application is generally run as a networked application with up to 40 people using the application simultaneously, and combined with design issues already mentioned, this has resulted in serious concurrency issues with several users being assigned the same primary key value. This == BIGNow I need to sort this out (guess what I will be doing this weekend!! Great.). I have thought about maybe using a mutex around the code that calls the Access insert queries; not the neatest of solutions, but it would be the quickest. Ultimately though, I would like to have the database corrected and have proper primary key values in place. But the application is currently running at about 15 different sites, so I need to do some sort of batch update of the database.

There are three tables being updated by three separate sub routines. Two work fine, one does not.
In trying to resolve the issue I test one field at a time. The test Access query and the code only reference the one field to change and two ID fields. The program runs but the field is not updated. The table has 42 fields to be updated when I get it working.
The Access query is:
