Call a stored procedure from Run Activity

[clinterman]

I have a stored procedure that I would like to call from Run Activity.

Running the procedure from TOAD works fine.

The Activity is defined as
nuRunQuery("CALL DELETE_SPIDER();");
and I tried
nuRunQuery("CALL DELETE_SPIDER()",false);
nuRunQuery("CALL DELETE_SPIDER()",true);


Run Activity doesn't. I get the errorscreen:
SQL

SELECT ``.* FROM `` WHERE = '14f7f4a062527c'
Transaction

No Transaction.
Error

1103: Incorrect table name ''

clinterman,

nuBuilder doesn't work with stored procedures.

Sorry about that.

Problem solved:

I can call a stored procedure using in "Custom Code after save"
$s = "CALL my_stored_procedure(" . $recordID . ")";
db_query($s);

Also with one modification and an extra php you can call stored procedures from Run Activity

I added to common.php after line 22: include('dbfunctions.php');
include ('mydbfunctions.php');

then I setup mydbfunctions.php as a copy of dbfunctions.php and started to add functions
function dbCallStoredProcedure1() {

$db = nuRunQuery(''); // returns $db[0]=$DBHost; $db[1]=$DBName; $db[2]=$DBUserID; $db[3]=$DBPassWord;
$link = mysql_connect($db[0], $db[2], $db[3]);
if (!$link) { die('Could not connect: ' . mysql_error());}
mysql_select_db($db[1]);
$t = mysql_query("CALL Stored_Procedure1");
return $t;
}

I just have not yet figured out how in this last option I can pass variables. Maybe somebody knows and want to update this post as we can all learn from this

Maybe this will help?

I have NOT tried this yet, as I am working on another problem, and happened to run across this accidentally.. It will be of value to me, and I will be trying it at some point soon as I would LOVE to use Stored Procedures (I'm a PostGreSQL fan myself, and use stored procedures for everything, so I'm hopeful this will work)..

If anyone tries it before I do, let me know the result, and I certainly shall respond here with my success/failure.

specifically:


If you're using stored procedures and mysql_error() returns "PROCEDURE storedProcedureName can't return a result set in the given context", you need to pass an additional flag (CLIENT_MULTI_RESULTS) to mysql_connect() as such:
mysql_connect($hostname, $username, $password, true, 131072);

Some other sources say that you should use 65536. 65536 is actually the flag to allow multiple statements in a single mysql_query(), and is a security issue. The reason it allows you to receive results from stored procedures is because it implies 131072. To be safe, use 131072 over 65536.

When you connect and expect to use a stored procedure,you must pass a special flag to MySQL via the connect command, otherwise you will not get the results returned, and it will result in this error:
PROCEDURE AlexGrim.GetStats_ForumCategories can't return a result set in the given context

To fix this, change you connection string, adding ",false,65536" as the last 2 fields:
$this->con = mysql_connect($this->h,$this->u,$this->p,false,65536);
