>             Project: Asterisk
>          Issue Type: Bug
>      Security Level: None
>          Components: Functions/func_odbc
>    Affects Versions: 13.21.0
>            Reporter: Alexei Gradinari
>
> The functions acf_odbc_read/cli_odbc_read ignore a number of columns in the  SQLNumResultCols.
> If the number of columns is zero it means no data.
> In this case, a SQLFetch function has to be not called,
> because it will cause an error.
