odbc_pconnect
odbc_exec() returns BOOLEAN if the query doesn't return a result set.
If the query returns a result set, odbc_exec() returns a resource to that result set.
odbc_prepare
(PHP 4, PHP 5)
odbc_prepare — Prepares a statement for execution
Descrierea
resource odbc_prepare
( resource $connection_id
, string $query_string
)
Prepares a statement for execution. The result identifier can be used later to execute the statement with odbc_execute().
Some databases (such as IBM DB2, MS SQL Server, and Oracle) support stored procedures that accept parameters of type IN, INOUT, and OUT as defined by the ODBC specification. However, the Unified ODBC driver currently only supports parameters of type IN to stored procedures.
Parametri
- connection_id
-
Identificatorul conexiunii ODBC, accesaţi odbc_connect() pentru detalii.
- query_string
-
The query string statement being prepared.
Valorile întroarse
Returns an ODBC result identifier if the SQL command was prepared successfully. Returns FALSE on error.
Exemple
Example #1 odbc_prepare() example
In the following code, $res will only be valid if all three parameters to myproc are IN parameters:
<?php
$a = 1;
$b = 2;
$c = 3;
$stmt = odbc_prepare($conn, 'CALL myproc(?,?,?)');
$res = odbc_execute($stmt, array($a, $b, $c));
?>
If you need to call a stored procedure using INOUT or OUT parameters, the recommended workaround is to use a native extension for your database (for example, mssql for MS SQL Server, or oci8 for Oracle).

Is it just me or is the code above misleading? It makes it look like odbc_execute() returns a resource suitable, say, for passing to one of the odbc_fetch_* functions.
In fact, odbc_execute() returns a boolean, which simply indicates success (TRUE) or failure (FALSE). The variable to pass to odbc_fetch_* is the same one that you pass to odbc_execute():
<?php
$res = odbc_prepare($db_conn, $query_string);
if(!$res) die("could not prepare statement ".$query_string);
if(odbc_execute($res, $parameters)) {
$row = odbc_fetch_array($res);
} else {
// handle error
}
?>

Use this example for IBM DB/2:
$q = "update TABLE set PASS=? where NAME=?";
$res = odbc_prepare ($con, $q);
$a = "secret"; $b="user";
$exc = odbc_execute($res, array($a, $b));
