it simply means there is no column with the name categoty in tblcategory. I think you have a spelling mistake , in database your column name is category but in command you are using categoty . use the right column name and your problem will be resolved.

Please share your table structure

Spelling error in column name I think

Hi, Please check your select statement. Column you are using in select statement is not there in tblcategory. You have use categoty. I think it will be category not categoty.
