QueryConnect = "SELECT * From users Where BranchAccess=@BAccess"

CommandConnect = New MySqlCommand(QueryConnect, DataConnection)

CommandConnect.Parameters.Add("@BAccess", MySqlDbType.VarChar).Value = SBIDLabel.Text

Answer 1

just swap your parameter and column and use IN keyword.

QueryConnect = "SELECT * From users Where @BAccess IN (BranchAccess)"

see dbfiddle

Answer 2

Thanks For Your Answer Guys i was able to find a solution using this

QueryConnect = "SELECT * FROM users WHERE FIND_IN_SET(@BAccess, BranchAccess)>0"

CommandConnect = New MySqlCommand(QueryConnect, DataConnection)

CommandConnect.Parameters.Add("@BAccess", MySqlDbType.VarChar).Value = SBIDLabel.Text
