Bug Type: MSSQL related
Operating System: Win XP Pro SP2
PHP Version: 5.1.2RC1
Assigned To: fmk
New Comment:
1) BIGINT is not a known data type for MS SQL Server 6.5. Microsoft has
not updated the API (used for the mssql extension) since this version of
the server.
You can use the php_dblib.dll extension this is build using FreeTDS and
is more up to date.
2) You should use msql_init(), mssql_bind() and mssql_execute()
functions when working with storrd procedures. mssql_query() can handle
multiple results but it can not return output parameters or return
values.
Please make sure to use mssql_next_result() to process additional
result sets.

Sorry, my comments in PHP code before running the 1st query might be
misleading (forgot to modify during submission to here). Discard them
and please refer to the explanation.
Thanks.

Description:
------------
Hi,
I am disappointed about the way PHP communicates with MS SQL Server and
handles queries. I costed me more than a week to find out this.
Basically, it is related to BIGINT data types, I guess.
Here is the test case:
Have a simple table including a field of type bigint.
Have a procedure reading data from it, returning an output field of
type bigint and a resultset on the fly.
Have a simple SQL statement to declare a temp variable of type bigint,
calling this procedure and getting the output.
Use this through mssql_query() function.
Have another simle select query.
I expect 2 resultsets from the 1st query (2 values output) and another
from the 2nd query.
But I have 1 resultset from the 1st query (1 value)
and a failure for a correct SQL statement.
Because it is understood that connection is lost somehow during the 1st
query without any error message.
If you change every BIGINT to INT it works fine.
However, I do NOT think this is the solution.
Reproduce code:
---------------
--sql statements to prepare database
CREATE TABLE [T1] (
[id] bigint NOT NULL,
[name] nvarchar(50) NOT NULL,
PRIMARY KEY CLUSTERED ([id])
)
GO
INSERT INTO [T1] ([id], [name])
VALUES
(1, 'abc')
GO
INSERT INTO [T1] ([id], [name])
VALUES
(2, 'def')
GO
CREATE PROCEDURE my_proc
@output1 bigint output
AS
BEGIN
--set the value
select top 1
@output1 = id
from t1
--return recordset for php
select @output1 as MY_BIG_INT_output1
END
GO
--end of sql
<?php
//PHP file:
if($dbh = mssql_connect('host\sqlserver', 'dba', 'pwd')){
echo 'Host connected<br>';
if(mssql_select_db('mydb')){
echo 'Database selected!<br>';
$input1=2;
$sql ="
DECLARE @o BIGINT
EXECUTE my_proc @o output
SELECT @o as output2
"
;
echo 'Running SQL:<br><pre>'.$sql.'</pre>';
//if there is an emp record
// there will be 3 result sets: emp, return_value, output1
//else
// there will be 2 result sets: return_value, output1
if($rs = mssql_query($sql)){
do{
while($row = mssql_fetch_assoc($rs)){
echo '<pre>'.print_r($row,true).'</pre>';
}
} while(mssql_next_result($rs));
mssql_free_result($rs);
}else{
echo 'Error: '.mssql_get_last_message().'<br>';
}
//try another query
$sql2='SELECT TOP 1 * FROM t1';
echo 'Running SQL:<br><pre>'.$sql2.'</pre>';
if($rs2 = mssql_query($sql2)){
while($row2 = mssql_fetch_assoc($rs2)){
echo '<pre>'.print_r($row2,true).'</pre>';
}
mssql_free_result($rs2);
}else{
echo 'Error: '.mssql_get_last_message().'<br>';
}
}else{
echo 'Database selection failed!';
}//end if select db
mssql_close($dbh);
}else{
echo 'Host connection failed!';
}//end if connection
//end of PHP file
?>
Expected result:
----------------
Host connected
Database selected!
Running SQL:
DECLARE @o bigint
EXECUTE my_proc @o output
SELECT @o as output2
Array
(
[MY_BIG_INT_output1] => 1
)
Array
(
[output2] => 1
)
Running SQL:
SELECT TOP 1 * FROM t1
Array
(
[id] => 1
[name] => abc
)
//// or an error message/warning if a particular datatype is not
supported, etc.
Actual result:
--------------
Host connected
Database selected!
Running SQL:
DECLARE @o bigint
EXECUTE my_proc @o output
SELECT @o as output2
Array
(
[MY_BIG_INT_output1] => 1
)
Running SQL:
SELECT TOP 1 * FROM t1
Warning: mssql_query() [function.mssql-query]: Unable to set query in
...test_proc.php on line 34
