[RESOLVED] Error in searching access database records by ado.net

[HOTFIX]

Hi everybody…
I’ve made access database table using Microsoft Access 2007 and exported as aceess2000 .mdb file.

Table name: store

Table fields:
Item ID: AutoNumber
Item Part Number: Text
Item Descriptions: Text
Item Location: Text
Item Quantity: Text

Then I’ve made OleDb connection thorough vb.net 2008
After that I’ve added two type searches exact and general by radio button.
The problem is the search command return an error line “Syntax error (missing operator) in query expression”
