Group(3) would be null.

include (“connect.php”);
$id = $_GET['id'];
$qP = “SELECT * FROM source_table WHERE id = ‘$id’ “;

function find()
{
$findit = mysql_query(“SELECT * FROM source_table WHERE id=’id’”);
}
function copy()
{
$copyit = mysql_query(“CREATE temp_table SELECT * FROM source_table WHERE id=’$id’”);
}
function alter()
{
$alterit = mysql_query(“ALTER TABLE temp_table DROP COLUMN id”);
}
function increment()
{
$revision++;
$incrementit = mysql_query(“UPDATE temp_table.revision SET revision=’$revision’”);
}
function insert()
{
$insertit = mysql_query(“INSERT INTO source_table SELECT null, * FROM temp_table”);
}
function drop()
{
$dropit = mysql_query(“DROP temp_table”);
}

mysql_close($con);

CLOSE CONNECTION

Think i’m on the right track, with creating a temp_table and doing the work there, but its not working.

Will let you know.

Thanks

Unfortunately, I don’t need to create any new tables, I want to add the data I already have, to the database again, but changing a small number of variables (eg the revision level afrom A to B). Have been using a similar script as that found on your link, but my trouble comes in adding the data to the same table.

——————————————————-
| ID | Part Number | Revision |
——————————————————-
| 1 | 123456 | A |
| 2 | 456789 | A |
——————————————————-

What I need, is a way to auto increment the part number to rev B, create a new ID, in this case 3, but keep the part number the same. And add the whole lot, back into the tablea as follows.

——————————————————-
| ID | Part Number | Revision |
——————————————————-
| 1 | 123456 | A |
| 2 | 456789 | A |
| 3 | 456789 | B |
——————————————————-

From what I know of PHP, the following script should work, but when you try to initiate it, I get nothing back but errors. Assume I have just three columns, ID, Part Number, and Revision, the following should work.

INSERT INTO tablea (partnumber, revision) SELECT * FROM tablea WHERE id=’id’

Any ideas ?

I’ve tried to add it to an existing php script, but it isn’t working. I think the way I have it formatted is wrong, but could really use an example as all of the info I have found on this so far, only includes snippets, which are difficult to piece together for a PHP newbie like myself.

What I would like to do, is copy a row from a table, and insert most of the content into the same table, but with an incremented value as follows. Copy Part_number 1 Revision A, Insert Into same table as Revision B. Thats it. It sounds easy enough, but getting it to work is becoming a pain.
I’m self taught, and starting to think i’m missing some fundamental PHP knowledge which most people would take for granted.

I was under the impression I’d be able to use something like:

$id = $_GET['id'];
$select = “SELECT * FROM table WHERE id = ‘$id’ “;

$revision=”revision”;
$revision++;

TO CREATE
PartNumber Rev A [ COPY BUTTON ]
PartNumber Rev B

Incrementing an existing row with a new revision sounds straightforward enough, but actually writing the script to allow it is proving very difficult. Does anyone have a full script, which I may be able to tinker with? The simpler the better please.

I’m afraid I can’t post what I have so far, as (1) its complete garbage, and (2) its for a client who values their privacy.

Any help you could provide would be greatly appreciated.
