mssql_fetch_array

(PHP 4, PHP 5, PECL odbtp:1.1.1-1.1.4)

mssql_fetch_array — Fetch a result row as an associative array, a numeric array, or both

Описание

array mssql_fetch_array ( resource $result [, int $result_type ] )

mssql_fetch_array() is an extended version of mssql_fetch_row(). In addition to storing the data in the numeric indices of the result array, it also stores the data in associative indices, using the field names as keys.

An important thing to note is that using mssql_fetch_array() is NOT significantly slower than using mssql_fetch_row(), while it provides a significant added value.

Список параметров

result: The result resource that is being evaluated. This result comes from a call to mssql_query().
result_type: The type of array that is to be fetched. It's a constant and can take the following values: MSSQL_ASSOC, MSSQL_NUM, and the default value of MSSQL_BOTH.

Возвращаемые значения

Returns an array that corresponds to the fetched row, or FALSE if there are no more rows.

Примечания

Замечание: Имена полей, возвращаемые этой функцией, регистро-зависимы.

Замечание: Эта функция устанавливает NULL-поля в значение NULL PHP.

I just spent a few hours trying to get ntext data with this function, CASTing and CONVERTing every which way, and scouring the 'net. Nothing worked, I just got a NULL.



Then on a whim I tried it with mssql_fetch_row instead, and that DOES work.

Note that if you fetch varchar fields larger than 255 letters the result will be cut off at 255 letters. 



To prevent this you have to do a CONVERT(TEXT,data_field) for this fields in your select clause.

Calling this function with the option second parameter is causing a "Wrong parameter count" message. If you run into this problem, you can get the same effect by calling different functions:



mssql_fetch_array: MSSQL_BOTH

mssql_fetch_assoc: MSSQL_ASSOC

mssql_fetch_row: MSSQL_NUM

There is any option like skip or go next ! I am using a while clause inside:

  While ($row=mysql_fetch_array($result))

    while ($row["Brand_name"]=$gr){

     ....

So I am printing different TD from classes and when I finish cycling the fields I want to "skip" to next record !

Allthough probably obvious to people who have used the functions available to other databases it during writing is not present in this entry that result type can be entered as MSSQL_ASSOC or MSSQL_NUM, and the default value when nothing entered being MSSQL_BOTH

In response to my last post:



After further testing, it appears as though the null column bug only affects windows installations. On my linux installation using freetds-0.61.2, the function behaves properly. It must exist either in the php_mssql.dll or the Microsoft connection libraries. And since I use this functionality through ASP as well (which uses the Microsoft connection libraries), it would lead me to believe that it's an issue within the php_mssql.dll.

Using the $row = mssql_fetch_array($result)



A null value will return 0, this is a problem if you are using 0 and some identifier for a value.  you should convert all nulls to something like -1 or "NO VALUE"

After extensive testing, the above statements both seem to be true. You *can* distinguish between 0 and null values in PHP; however, the mssql_fetch_array function does not set null colums to the php NULL value. 



if ($row['Null_Column'] === 0) { print('pass'); }



A null column passes the above test. Seems to be a bug in the function.

The array_walk function is also useful for stripping the whitespace returned in an mssql_query.



function modify_field(&$array) {

    $array = trim($array);

}



$query = "select * from dbo.table where value = '0'";

$result = mssql_query($query) or die;



while ($row = mssql_fetch_array($result)) {

    // This will call the above function.

    array_walk($row, 'modify_field'); 

    array_push($eventresults, $row);

}



An added benefit is that you can expand the modify_field function to handled unexpected returned column data.

from php-dev mailing list article - 

#26012 [Bgs]: mssql_fetch_array 



"Previously mssql data was always rtrimed, however that's wrong because it modifies the original data. This caused a problem for people who needed those trailing space. Ultimately, the job of database extension is to fetch the data as is (like other db extensions already do) and not to mangle it in any way."



moving from <4.3.4 to a higher version you will have this now:



$query = "Select dumb_spaces from dbo.table where weak_sause = 'true'";

$result = mssql_query($query) or die("Spicy Sause! Query = $query");



while($line = mssql_fetch_array($result, MSSQL_ASSOC) {

     foreach($line as $bs_trim) {

          //Trim whitespace from end of query

          $bs_trim = rtrim($bs_trim);

          echo "Clean!".$bs_trim;

     }

}

Apparently php 4.0.6 does not support the second parameter. When used the error sounds

"Wrong parameter count for mssql_fetch_array"

Note that the second parameter is the same as the msql version of this function (http://www.php.net/manual/en/function.msql-fetch-array.php) with the constants (MSQL_ASSOC, MSQL_NUM, and MSQL_BOTH) changing to MSSQL_.





Also note that if you don't specify this parameter you'll get both the numbers and column names, which can cause some frustration.

It seems that this function creates arrays wich keys can not be longer than 30 chars. So when you're having a DB-field like "this_is_a_very_long_db_field_name"

its array-key is cut off after 30 chars and you will have to access the value with

rs["this_is_a_very_long_db_field_n"]
