Get result data

### 参数

  The ODBC resource.

`field`

  The field name being retrieved. It can either be an integer containing the column number of the field you want; or it can be a string containing the name of the field.

### 返回值

### 范例

The first call to odbc_result() returns the value of the third field in the current record of the query result. The second function call to odbc_result() returns the value of the field whose field name is "val" in the current record of the query result. An error occurs if a column number parameter for a field is less than one or exceeds the number of columns (or fields) in the current record. Similarly, an error occurs if a field with a name that is not one of the fieldnames of the table(s) that is(are) being queried.

Example #1 odbc_result() examples

    <?php
    $item_3   = odbc_result($Query_ID, 3);
    $item_val = odbc_result($Query_ID, "val");
    ?>

### 注释

Field indices start from 1. Regarding the way binary or long column data is returned refer to odbc_binmode() and odbc_longreadlen().
