PDO无法将新记录插入Access数据库，但可以在同一连接中读取和删除

Question

I have a problem. I have a ms Access DB files, which I have to read and modify (delete and insert records). I use PDO odbc. And I have strange situation where I can read and delete but I cann't insert new records in DB with same connection. I have already checked insert string in ms Access and it works perfectly .
Here php code:

<?php

$path = getcwd() . "\\tempFolder\\MSDB.mdb";
$con = "odbc:DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=$path; Uid=; Pwd=;";
try
{
    $db = new PDO($con);
    $db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    //READ
    $cmd = "SELECT * FROM temp_HEADER WHERE [LINE-ID]='101'";
    $result = $db->prepare($cmd);
    $result->execute();
    $result = $result->fetch(PDO::FETCH_ASSOC);
    print_r($result); echo "<br/>";

    //DELETE
    $cmd = "DELETE FROM temp_HEADER WHERE [LINE-ID]='101'";
    $result = $db->prepare($cmd);
    $result->execute();
    echo "DELETE OK<br/>";

    //INSERT
    $cmd = "INSERT INTO temp_HEADER ([LINE-ID], PLANE, DISPLAY, X, Y, Z, LENGTH, SURF, ROCK, VARIA, LTYPE, NAME) "
    . "VALUES('101', '100', '', 100, 100, 100, 0, 0, '', 1, 'LINE', 'TEMP')";
    $result = $db->prepare($cmd);
    $result->execute();    
    echo "INSERT OK";

} catch (Exception $ex) {
    echo $ex->getMessage();
}

This code get me following result:

Array ( [LINE-ID] => 101 [PLANE] => 100 [DISPLAY] => [X] => 100.0 [Y] => 100.0 [Z] => 100.0 [LENGTH] => 0.0 [SURF] => 0.0 [ROCK] => [VAR] => 1 [LTYPE] => LINE [NAME] => TEMP [Ind] => 1041 ) 
DELETE OK
SQLSTATE[22018]: Invalid character value for cast specification: 39 [Microsoft][Driver ODBC Microsoft Access]Invalid character value for cast specification (null) (SQLExecute[39] at ext\pdo_odbc\odbc_stmt.c:254)

What is wrong with this?

ps: I tested this one script in several computers and some of them show all results well, but another - got error in insert command.

EDIT: Add type of fields:

LINE-ID - Text<br/>
PLANE - Text<br/>
DISPLAY - Text<br/>
X - Number(Double)<br/>
Y - Number(Double)<br/>
Z - Number(Double)<br/>
LENGTH - Number(Double)<br/>
SURF - Number(Double)<br/>
ROCK - Text<br/>
VARIA - Number(Long Integer)<br/>
LTYPE - Text<br/>
NAME - Text<br/>
Ind - AutoNumber(Long Integer)<br/>

EDIT: I have just written the same code in C# and everything is OK (I could read, delete and insert). I used the same sql queries as here, but I used oleDB. In this case I think that something wrong with odbc with pdo in php. Couldn't someone tell me how can I connect to DB via oleDB in php because fast search didn't get any result?

EDIT: I tried to use code with COM (OleDB). I repeated the same task with read, delete and insert. What I got:

variant Object 
DELETE OK
Source: Microsoft JET Database Engine
Description: type Mismatch

EDIT: I created mdb file and simple script with read, delete and insert function and put it here . This code doesn't work for me. If you can run it without problem, please, write down the version of your driver. I think the problem in driver. In my case, I've already tried to change ODBC shortcut from system32 into sysWOW64, but nothing changes.

Answer 1

According to this list , var is a reserved word in MS Access.

One of your variables is called var , so you are getting a syntax error. Wrap the name in square braces.

EDIT:

The error suggests that there is a type conflict between one of the columns and the value you are providing. In any case, the over-riding idea is the same. The connection is fine. The SQL has syntax errors.

Answer 2

What type is the "Display" field. You seems to be inserting it into the database, yet the print out says its a two dimensional array

Answer 3

how can I connect to DB via oleDB in php

To perform the INSERT via OLEDB you would use something like this

<?php
// this code requires the following php.ini directive:
//
// extension=php_com_dotnet.dll

$path = getcwd() . "\\tempFolder\\MSDB.mdb";
$con = new COM("ADODB.Connection"); 
$con->Open(
        "Provider=Microsoft.Jet.OLEDB.4.0;" .
        "Data Source=$path");

$cmd = "INSERT INTO temp_HEADER ([LINE-ID], PLANE, DISPLAY, X, Y, Z, LENGTH, SURF, ROCK, VARIA, LTYPE, NAME) "
    . "VALUES('101', '100', '', 100, 100, 100, 0, 0, '', 1, 'LINE', 'TEMP')";       

$con->Execute($cmd);

$con->Close();

If you are dealing with Unicode text (as you mention in the comments to the question) then I strongly suggest that you abandon the PDO_ODBC approach because it is doomed. PHP and Access ODBC do not play well together when Unicode characters are involved.

Answer 4

There is no point in preparing if you are going to harcode the value.

On the other hand it is a risk you are taking as you can make a mistake and data type won't match.

It looks like you are inserting coordinates, for instance a blank string ('') will not convert to float.

Try to prepare this query properly:

$cmd = "INSERT INTO 
        temp_HEADER (`[LINE-ID]`, `PLANE`, `DISPLAY`, 
                     `X`, `Y`, `Z`, `LENGTH`, `SURF`, 
                     `ROCK`, `VARIA`, `LTYPE`, `NAME`) "
    . "VALUES(  ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)";
$result = $db->prepare($cmd);
$success = $result->execute(array('101', '100', '', 
                                  100, 100, 100, 0, 0, 
                                  '', 1, 'LINE', 'TEMP'));    
if($success){
    echo "INSERT OK";
}else{
    echo "INSERT FAIL";
}
