范例

Example #1 mssql_execute() example

<?php
// Create a new statement
$stmt = mssql_init('NewBlogEntry');

// Some data strings
$title = 'Test of blogging system';
$content = 'If you can read this, then the new system is compatible with MSSQL';

// Bind values
mssql_bind($stmt, '@author',    'Felipe Pena',  SQLVARCHAR,     false,  false,   60);
mssql_bind($stmt, '@date',      '08/10/2008',   SQLVARCHAR,     false,  false,   20);
mssql_bind($stmt, '@title',     $title,         SQLVARCHAR,     false,  false,   60);
mssql_bind($stmt, '@content',   $content,       SQLTEXT);

// Execute the statement
mssql_execute($stmt);

// And we can free it like so:
mssql_free_statement($stmt);
?>

注释

Note:

If the stored procedure returns parameters or a return value these will be available after the call to mssql_execute() unless the stored procedure returns more than one result set. In that case use mssql_next_result() to shift through the results. When the last result has been processed the output parameters and return values will be available.

When calling a stored procedure which is using OUTPUT parameters, be sure not to pass them as NULL in mssql_bind. If you do this, the data received in output gets truncated to one character.

AgusQuiroga (21-Oct-2011 10:39)

SUBJECT: No OUTPUT parameter recieved on store procedure call.

If you call a store procedure who binds data to an OUTPUT parameter on a SQL Server 7 or later no response will be produced, or an error perhaps.

From the Free TDS documentation:

Output Parameters

I'm not getting my output parameters returned, but I seem to be doing everything right!

That's not a question!

Microsoft SQL Server 7 with SP3, and later versions, quietly changed (which is to say, broke) how they respond to queries that execute stored procedures with output parameters. Earlier servers let you send a query like EXECUTE A @P OUTPUT and fetch the output parameter as a special result row (technique varying by library). Newer servers simply don't send back that data. To elicit output parameters from them, you have to use the RPC protocols such as the DB-Library dbrpcparam.

ian_channing at hotmail dot com (24-Sep-2011 03:05)

Output parameters are cryptic to get out. Here's two examples, one if you have no results returned from your stored procedure, one if you do have results returned:
<?php
/**
 * using OUTPUT param with no results returned from stored procedure
 */
$outParamValue = 0;
mssql_bind($stmt, '@'.$outParamName, $outParamValue, $outParamType, $is_output = true);
mssql_execute($stmt, $skip_results = true);
/* N.B. If you don't use $skip_results = true you must use mssql_next_result as below **even if there are no results returned from the stored procedure** */
echo($outParamValue);

/**
 * using OUTPUT param with one result set returned from stored procedure
 */
$outParamValue = 0;
mssql_bind($stmt, '@'.$outParamName, $outParamValue, $outParamType, $is_output = true);
$result = mssql_execute($stmt);
echo($outParamValue); /* will still be 0 */
mssql_next_result($result); /* N.B. see the Note above about this */
echo($outParamValue); /* correct output */
?>

Regarding the "stored procedure execution failed" errors mentioned in previous posts -- in addition to using the data source name as defined in freetds.conf under Linux, you may encounter this error when attempting to call a stored procedure  after running a standard query with mssql_query()

Call mssql_free_result() before executing the stored procedure with mssql_execute() to clear this up.

<?php
$conn = mssql_connect($host, $user, $pass);
mssql_select_db('somedb', $conn);

// Call a simple query
$result = mssql_query('SELECT * FROM sometable', $conn);

// Release the result resource
mssql_free_result($result);

// Then execute the procedure
$proc = mssql_init('some_proc', $conn);
$proc_result = mssql_execute($proc);

// Etc...
mssql_free_statement($proc);
?>

In a similar way as one of the post above, when I was trying to execute a stored procedure, I was getting "stored procedure execution failed." However, mssql_query was working fine. Instead of changing the config file, I have found a way to execute stored procedure and return parameters from it in the SQL statement. Below is the example SQL

DECLARE @Success bigint, @oSuccess bigint;
DECLARE @UserID bigint, @oUserID bigint;
EXEC dbo.sp_Login @UserName='user',  @UserPassword='pass', @Success=@oSuccess OUTPUT, @UserID=@oUserID OUTPUT;
SELECT success=@oSuccess, userid=@oUserID;

Note, that I pass 2 parameters to the stored procedure and receive 2 parameters back. Also, I used ADODB connection to execute the sql.

A much simpler solution that allows you to keep the config in the PHP script is to force the TDS version by using putenv before you connect.

<?PHP
  putenv('TDSVER', '8.0');
  $dbc = mssql_connect('123.123.123.123:1433', 'user', 'pass');
?>

Anton Schattenfeld (02-Aug-2007 03:59)

To get info about table structure you can use such a query:

SELECT
  column_name,
  data_type,
  character_maximum_length,
  numeric_precision,
  column_default,
  is_nullable
FROM
  information_schema.tables t
  INNER JOIN
  information_schema.columns c
  ON
    t.table_catalog = c.table_catalog AND
    t.table_schema = c.table_schema AND
    t.table_name = c.table_name
WHERE    
  (c.table_name = 'TABLE_NAME')

I was pulling my hair out getting the error:
  "stored procedure execution failed"
when trying to run mssql_execute but you could run:
  $results = mssql_query('sp_test');
fine.

I was connecting using the string:
  $dbserver="xxx.xxx.xxx.xxx:1433";
  $cn = mssql_connect($dbserver, $dbuser, $dbpass);

where xxx is the IP address.

It seems that this doesn't work, you need to do the following:
edit your freetds.conf file and add the connection in here, eg:
[YourServer]
        host =xxx.xxx.xxx.xxx
        port = 1433
        tds version = 8.0

Then try and connect as:
$cn = mssql_connect('YourServer', $dbuser, $dbpass);

And it should work.  No idea why it doesn't work before, took me hours to find this out!

Manda Krishna Srikanth (18-Jan-2007 04:56)

While using stored procedures on SQL EXPRESS (and perhaps on SQL Server), you have to specify the column names in SELECT, instead of asterisk (*). Or else you will get some big Unicode error.

That is, instead of "select * from table",
use "select col1, col2 from table".

One more important thing, Before using mssql_execute, you MUST AND SHOULD use mssql_init. mssql_init will generate the MS Sql statement resource, which will be taken as input by mssql_execute. Here is an example,

<?php
if($conn = mssql_connect('localhost\SQLEXPRESS', 'krishna', 'srikanth')) echo 'Connected to SQLEXPRESS';

if(mssql_select_db("Northwind",$conn)) echo 'Selected DB: Northwind<BR>';

$sql_statement =  mssql_init("[Ten Most Expensive Products]", $conn);
$result=mssql_execute($sql_statement);

while ($row = mssql_fetch_assoc($result))
    print_r($row);
?>

If you need to get Output params from your stored procedure, make sure to use FreeTDS > 0.6.4... it has a bug that prevents some Output params from being set.

mpoletto at gmail dot com (21-Feb-2005 07:04)

The constant SQLINT4 is not working with datetime. Try using SQLVARCHAR.

SQL dot User at Yandex dot Ru (12-Jul-2004 05:38)

To receive output parameter from the procedure which returns one or several recordsets, try this code:

...
mssql_bind($my_procedure, "@OutputParameter", SQLVARCHAR, true);
$result = mssql_execute($my_procedure);
while(mssql_next_recordset($result)) {
## do something
}

after listing last recordset output parameter will be available (strange...).

If you do not need output recordsets, just parameters, try this:

mssql_bind($my_procedure, "@OutputParameter", SQLVARCHAR, true);
$result = mssql_execute($my_procedure, true);

P.S. Tested on PHP 4.3.5.

php version 4.3.2

Take care when using stored procedures returning multiple results, seems that if the first result is empty, the pointer will be automatically moved to the next result. As in this example:

CREATE PROCEDURE test
AS
SELECT 0 as zero WHERE 0 = 1
SELECT 1 as one
GO

After executing the stored procedure, mssql_num_rows will report one, ignoring the first result.

eliseo at olografix dot org (12-Oct-2003 06:23)

After many attempt I resolved the return output of a store procedure on Win2003 box, MSSQL7 and PHP 4.3.
I have problem to process the result from store procedure strCheckUser, and I must to set a R variable, that must be returned from the last select operation (Select @R as R) see below.

----------------------------
/*
Store procedure to CheckUser Exist
*/
CREATE PROC strCheckUser 
(
@AccountLO varchar(20) ,
@PasswordLO varchar(20)
)
AS
BEGIN
DECLARE @R INT
IF (SELECT count(*) as count FROM tbl_users WHERE AccountLO = @AccountLO and PasswordLO=@PasswordLO
) = 0
SET @R = '0'
END

BEGIN
IF (SELECT count(*) as count FROM tbl_users WHERE AccountLO = @AccountLO  and PasswordLO=@PasswordLO
) = 1
SET @R = '1'

END

Select @R as R

GO
-------------------------

This is the php page
<?

.....
.....
$AccountLO="myuser";
$PassowrdLO="mypass";

$result=mssql_query("strCheckUser ".$AccountLO.", ".$PasswordLO."");
//echo gettype($result);
$arr = mssql_fetch_assoc($result);       
echo $arr["R"];

......
......
?>

No $arr["R"] print 1 if the user exist and 0 if no exist

Thanks to duarte at uma dot pt for the suggestion

The easiest way to use a stored procedure is:

$Result = mssql_query("StoredProcedureName Var1, Var2, Var3...");

$Result is then just like any other result set. You can get the output parameters by:

$arr = mssql_fetch_row($Result);

$OutputParam1 = $arr[0];
$OutputParam2 = $arr[1];

brian_caughlin at hotmail dot com (06-Aug-2003 07:04)

Regarding Output Parameters and RETVAL: A change that appears to have begun around 4.3.

According to the documentation and previously posted comments, if a stored procedure returns only one Recordset, you could retrieve the RETVAL and Output Params right away.  THIS IS NO LONGER THE CASE.  Beginning around 4.3, you must always use the mssql_next_result() function if any recordset is returned at all.

If you consider the example posted below by fjortizATcomunetDOTes on 26-Dec-2001...

[...]

// Execute the Stored Proc
$result=mssql_execute($stmt);

// Get the recordset
$arr=mssql_fetch_row($result);
print ("Answer: " . $arr[0] . "
" );

// NEW for 4.3: Switch to the next Recordset
// Since there was only one recordset, it will return false...
mssql_next_result($result);

// And now RETVAL and Output Params are accessible...
print ("RETVAL = $val ; intval = $ival ; floatval = $fval ; string = $sval");

[...]

There is also another way, and that is to use a new optional skip parameter on the execute.

mssql_execute($stmt, true);

This appears to ignore any recordsets, allowing you to get at the retval and output parameters immediately.

For more information, please see Bug #21089.

fjortizATcomunetDOTes (26-Dec-2001 02:01)

After initializing a stored procedure
with mssql_init, and binding all the
parameters (and return value if needed)
with mssql_bind, you can execute the
statement with mssql_execute.

Parameters:
- stmt: statement resource obtained with
mssql_init.

From here, you can use any of the other
mssql_* functions to retrieve the
recordsets as if you had called
mssql_query. Any T-SQL error will also
be reported in the same way. The
variables passed by reference for OUTPUT
and RETVAL parameters will be filled
with the right values.

Now, an example:

if we have this procedure:

CREATE PROCEDURE [procedure]
(
   @sval varchar(50) OUTPUT,
   @intval int OUTPUT,
   @floatval decimal(6,4) OUTPUT
) AS

if @intval is null
    select '@intval is null' as answer
else    
    select '@intval is NOT null' as answer

set @sval='Hello ' + @sval
set @intval=@intval+1
set @floatval=@floatval+1

return 10

We can use this PHP code:

<?php

$conn=mssql_connect("myhost","user","pwd");

if ($conn) {
    mssql_select_db("mydb",$conn);
   
    $stmt=mssql_init("procedure",$conn);
    mssql_bind($stmt,"RETVAL",&$val,SQLINT4);

    $ival=11;
    $fval=2.1416;
    $sval="Frank";
   
    mssql_bind($stmt,"@sval",&$sval,SQLVARCHAR,TRUE);   
    mssql_bind($stmt,"@intval",&$ival,SQLINT4,TRUE);
    mssql_bind($stmt,"@floatval",&$fval,SQLFLT8,TRUE);
   
    $result=mssql_execute($stmt);

    $arr=mssql_fetch_row($result);
    print ("Answer: " . $arr[0] . "<br>" );
    print ("RETVAL = $val ; intval = $ival ; floatval = $fval ; string = $sval");
   
    mssql_close($conn);
}
else print("ooops!");
?>


Hope it helps. Good luck!
