oci_field_name

(PHP 5, PHP 7, PECL OCI8 >= 1.1.0)

oci_field_name返回字段名

说明

string oci_field_name ( resource $statement , int $field )

oci_field_name() 返回与字段数字索引(从 1 开始)相对应的字段名。

Example #1 oci_field_name() 例子

<?php
    $conn 
oci_connect("scott""tiger");
    
$stmt oci_parse($conn"SELECT * FROM emp");
    
oci_execute($stmt);

    echo 
"<table border=\"1\">";
    echo 
"<tr>";
    echo 
"<th>Name</th>";
    echo 
"<th>Type</th>";
    echo 
"<th>Length</th>";
    echo 
"</tr>";

    
$ncols oci_num_fields($stmt);

    for (
$i 1$i <= $ncols$i++) {
        
$column_name  oci_field_name($stmt$i);
        
$column_type  oci_field_type($stmt$i);
        
$column_size  oci_field_size($stmt$i);

        echo 
"<tr>";
        echo 
"<td>$column_name</td>";
        echo 
"<td>$column_type</td>";
        echo 
"<td>$column_size</td>";
        echo 
"</tr>";
    }

    echo 
"</table>\n";
    
oci_free_statement($stmt);
    
oci_close($conn);
?>

Note:

在 PHP 5.0.0 之前的版本必须使用 ocicolumnname() 替代本函数。该函数名仍然可用,为向下兼容作为 oci_field_name() 的别名。不过其已被废弃,不推荐使用。

Beware, the field index starts with 1, not 0. It's a bit counter-intuitive.

This does not work for empty tables.
