PHP - Manual: ibase_execute

ibase_execute

(PHP 5, PHP 7 < 7.4.0)

ibase_executeExecute a previously prepared query

说明

ibase_execute(resource $query, mixed ...$values): resource

Execute a query prepared by ibase_prepare().

This is a lot more effective than using ibase_query() if you are repeating a same kind of query several times with only some parameters changing.

参数

query

An InterBase query prepared by ibase_prepare().

values

返回值

If the query raises an error, returns false. If it is successful and there is a (possibly empty) result set (such as with a SELECT query), returns a result identifier. If the query was successful and there were no results, returns true.

注意:

This function returns the number of rows affected by the query (if > 0 and applicable to the statement type). A query that succeeded, but did not affect any rows (e.g. an UPDATE of a non-existent record) will return true.

范例

示例 #1 ibase_execute() example

<?php

$dbh 
ibase_connect($host$username$password);

$updates = array(
    
=> 'Eric',
    
=> 'Filip',
    
=> 'Larry'
);

$query ibase_prepare($dbh"UPDATE FOO SET BAR = ? WHERE BAZ = ?");

foreach (
$updates as $baz => $bar) {
    
ibase_execute($query$bar$baz);
}

?>

ibase_execute only return resource id not the actual result, you need to use ibase_fetch_row or ibase_fetch_object to retrieve actual result.

On the example above given by anthony
it should be like these

$dbh = ibase_connect ( $host, $username, $password ) ;
$stmt = 'SELECT * FROM "EMPLOYEE" WHERE "SALARY" = ? AND "DEPT_CD" = ? ;' ;
$prep = ibase_prepare ( $dbh, $stmt ) ;

$salary = Array ( "10000", "25000", "33000", "48000" ) ;
$dept_cd = 'SALES' ;

foreach ( $salary as $val ) {
   $res = ibase_execute ($prep, $val, $dept_cd);
   $taxForm[$val] = ibase_fetch_row ($res);
}

For variable argument list in ibase_execute you can use folowing functions:

For PHP >= 4.0.4:

function db_execute($stmt,$data)
{
    if(!is_array($data))
        return ibase_execute($stmt,$data);
    array_unshift($data,$stmt);
    $rc=call_user_func_array('ibase_execute',$data);
    return $rc;
}

For any version of PHP:
function db_execute($stmt,$data)
{
    if(!is_array($data))
        return ibase_execute($stmt,$data);

    $params = array();
    while( list($k,$v) = each($data) )
        $params[$k] = '$data['.$k.']';
    eval('$rc=ibase_execute($stmt,'.join(',',$params).');');

    return $rc;
}
