DELETE Query Functions in Access but not in VB.NET

[gponto18]

I have a very frustrating and confusing problem here; I have a SQL query that functions perfectly well in Access however when I code it in VB.NET it does not yield the desired results;here is the code:

        Dim oledbConnection As New OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & InstallLocation & "SDE.mdb;User Id=admin;Password=;")
        oledbConnection.Open()
 
        Dim oledbCommand As New OleDb.OleDbCommand("DELETE Sheet1.F4 FROM Sheet1 WHERE (((Sheet1.F4) Is Null)) OR (Sheet1.F4) LIKE '*E*';", oledbConnection)
        oledbCommand.ExecuteNonQuery()
        oledbConnection.Close()

The query runs and all nulls are dropped from the table, however none of rows that contain "E" get dropped.

Any advice would be greatly appreciated.

To narrow down the problem a bit, this line executes but does not delete anything from the table, even though when run in Access, it works fine:

DELETE Sheet1.F4 FROM Sheet1 WHERE (Sheet1.F4) LIKE '*E*';

I suggest removing the ";", not used to access in sql we use %. However does seem like a syntax problem.

Thank you for your reply; I tried your suggestion, unfortunately removing the ";" has no appreciable effect.

What is particularly vexing about this problem is that the statement works perfectly in Access but not in VB.NET.

Well I was able to solve this problem by using the Access Interop Libraries and running the SQL Query internally in Access.

Somehow though I think there must be a better way to do this.

if you want to execute your query by using the oledbcommand (that would improve your app performance, I guess...) you should replace the star sign ( * ) with a percent sign ( % ) on your LIKE Operator.

That should solve the problem, I figure it out that , after several days.

Check your code again here, I made the correction:

Dim oledbConnection As New OleDb.OleDbConn ection("Provide r=Microsoft.Jet .OLEDB.4.0;Data Source=" & InstallLocation & "SDE.mdb;Us er Id=admin;Passwo rd=;")
oledbConnection .Open()

Dim oledbCommand As New OleDb.OleDbComm and("DELETE Sheet1.F4 FROM Sheet1 WHERE (((Sheet1.F4) Is Null)) OR (Sheet1.F4) LIKE '%E%';", oledbConnection )
oledbCommand.Ex ecuteNonQuery()
oledbConnection .Close()

PS. Remove the ";" anyway. =]
