[Fri Feb 22 12:54:15 2008] [error] [client] PHP Warning: odbc_exec() [function.odbc-exec]: SQL error: [unixODBC][FreeTDS][SQL Server]Could not find stored procedure 'SHOW'., SQL state 37000 in SQLExecDirect in /srv/www/htdocs/hu/Proj1/test.php on line 9

The test source program is:

// connect to DSN MSSQL with a user and password
$connect = odbc_connect("DSNNAME", "user", "passwd") or die
("couldn't connect");
print "connection ok";
odbc_exec($connect, "use SwitchCenterDB");
print "SwitchCenterDB ok";
$result = odbc_exec($connect, "SHOW TABLES");
print(odbc_result($result, "CompanyName") .
' ' . odbc_result($result, "ContactName") . "\n");
--- end odbctest.php --

Warning: odbc_fetch_row(): 9 is not a valid ODBC result resource in /var/www/localhost/htdocs/customer.microprecision.com/gage.php on line 182

and my code:

// List Events For This Instrument
$sql2="SELECT * FROM events where events.company = '$custid' and ".
"gage_sn = '$cal' and ".
"(event_type like '%cal%' or event_type = 'Repair' or event_type = 'Op-Check')";
//echo $sql2;
//echo $cal;
if (!$rs2)
{exit("Error in SQL");}

Event Type
Cal Date
Calibration Result

odbc_fetch_row($rs2, 0);

$edate = date("M-j-Y", strtotime($edate));

The first error is the real one: You're feeding it something it doesn't know how to deal with. A bit of googling comes up with 'show tables' being a MySQL-ism - not something SQL Server is going to understand.

The other errors come from not checking the result set before trying to use it. ;-)

I am by no means an expert on your topic but something did catch my eye. The line in your sample code:
print(odbc_result($result, "CompanyName") .
' ' . odbc_result($result, "ContactName") . "\n");

appears to me to have an extra ) between "\n" and the ;

Just a guess but if that is really in the code that could be all or part of the problem.

Happy hunting!
