select command denied to user: A Misidentified Error

In a MySQL-based web application, you may encounter the error "select command denied to user ''@'' for table ''". While this error typically suggests a permissions issue, it can also be triggered by a different cause, as exemplified in the provided code.

The issue arises in line "MySqlDataReader result1 = command1.ExecuteReader();" of the code. However, the underlying problem lies in the SQL statement "Select Strike,LongShort,Current,TPLevel,SLLevel from json.tbl_Position where TradeID = '" i "'"". Specifically, the table name is referenced as "json.tbl_Position".

The error occurs because the table "json.tbl_Position" does not exist in the database. In the provided code, the table name should be "jsontest.tbl_Positions" instead. Correcting this misnomer will resolve the issue without altering any permissions.

It's important to note that this specific cause of the "select command denied" error is not directly reflected in the error message. Therefore, it's crucial to investigate the underlying SQL statement carefully to identify any potential table references that may be causing the issue.
