Oracle-00972：标识符太长我的SQL出了什么问题？

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.
