Oracle-00972：标识符过长我的SQL有什么问题？

Question

<?php

// This leaves the db connection in $conng require_once('/tms/http/html_docs/tease/csp/csp_tease.php');

    /* This a logging function. When called with:
     */

    function log_tkt_to_db($tkt_number, $date, $uid, $description, $conng)
    {
        echo "$tkt_number|$date|$uid|$description<br>";

        $sqlinsert = "insert into TEASE_TKTLOGS  VALUES ( \"$tkt_number\", \"$date\", \"$description\",  \"$uid\")";
        echo $sqlinsert . "<br>";
        $insert = OCIParse($conng, $sqlinsert);
        // OCIExecute($insert, OCI_COMMIT_ON_SUCCESS);
        OCIExecute($insert);
    }

log_tkt_to_db("00000000", "07/13/2012", "jt898u", "this a test, this is only a test", $conng);
?>  

I get this output:

00000000|07/13/2012|jt898u|this a test, this is only a test
insert into TEASE_TKTLOGS (TICKET, DATE_TIME, CHANGE_DESC, ATTUID) VALUES ( "00000000", "07/13/2012", "this a test, this is only a test", "jt898u")

Answer 1

There are multiple things wrong here.

1. The simplest answer is that you need to use single quote marks ( ' ) instead of double quotes (see String Literals in Oracle Database SQL Reference )
2. You really should use something like oci_bind_by_name instead of blindly inserting your values into the query. Saves you a parse and a potential SQL injection.
3. ociparse and ociexecute are deprecated as of PHP 5.4. Instead of these you should use, respectively, oci_parse and oci_execute .
