(PHP 4 >= 4.0.6, PHP 5)

fbsql_list_fields — List FrontBase result fields

说明

resource fbsql_list_fields ( string $database_name , string $table_name [, resource $link_identifier ] )

Retrieves information about the given table.

参数

database_name

The database name.

table_name

The table name.

link_identifier

A FrontBase link identifier returned by fbsql_connect() or fbsql_pconnect().

If optional and not specified, the function will try to find an open link to the FrontBase server and if no such link is found it will try to create one as if fbsql_connect() was called with no arguments

返回值

错误/异常

A string describing the error will be placed in $phperrmsg, and unless the function was called as @fbsql() then this error string will also be printed out.

范例

<?php
$link 
fbsql_connect('localhost''myname''secret');

$fields fbsql_list_fields("database1""table1"$link);
$columns fbsql_num_fields($fields);

for (
$i 0$i $columns$i++) {
    echo 
fbsql_field_name($fields$i) . "\n";;
}
?>

上例的输出类似于:

field1
field2
