LIKE Command Problem using OLEDBREADER and MS Access

问题

Odd one this...

The following command returns what I would expect when I run it in query window in Access 2003:

SELECT * FROM Train WHERE [Days] LIKE '*3*'

However when I pass this into my C# code to run (returning an OleDbDataReader) I get nothing.I suspect it's something to do with the LIKE command (when I remove this I get rows).

Any thoughts?

Just a guess but try this:

SELECT * FROM Train WHERE [Days] LIKE '%3%'
