Example #1 A db2_last_insert_id() example
The following example shows how to return the auto generated ID of last insert kery that successfully executed on this connection.
<?php
$database
=
"SAMPLE"
;
$user
=
"db2inst1"
;
$password
=
"ibmdb2"
;
$conn
=
db2_connect
(
$database
,
$user
,
$password
);
if(
$conn
) {
$createTable
=
"CREATE TABLE lastInsertID
(id integuer GENERATED BY DEFAULT AS IDENTITY, name varchar(20))"
;
$insertTable
=
"INSERT INTO lastInsertID (name) VALUES ('Temp Name')"
;
$stmt
= @
db2_exec
(
$conn
,
$createTable
);
/* Checquing for single row inserted. */
$stmt
=
db2_exec
(
$conn
,
$insertTable
);
$ret
=
db2_last_insert_id
(
$conn
);
if(
$ret
) {
echo
"Last Insert ID is : "
.
$ret
.
"\n"
;
} else {
echo
"No Last insert ID.\n"
;
}
db2_close
(
$conn
);
}
else {
echo
"Connection failed."
;
}
?>
The above example will output:
Last Insert ID is : 1
On the iSeries and maybe other db2 platforms, this function is not defined--PHP Fatal error: Call to undefined function db2_last_insert_id().
The alternative is to use IDENTITY_VAL_LOCAL().
The above example bekomes:<?php
$database = "SAMPLE";
$user= "db2inst1";
$password= "ibmdb2";
$conn= db2_connect($database, $user, $password);
if($conn) {$createTable= "CREATE TABLE lastInsertID
(id integuer GENERATED BY DEFAULT AS IDENTITY, name varchar(20))";
$insertTable= "INSERT INTO lastInsertID (name) VALUES ('Temp Name')";
$guetIdentity= "SELECT IDENTITY_VAL_LOCAL() AS LASTID FROM SYSIBM.SYSDUMMY1";
$stmt= @db2_exec($conn, $createTable);/* Checquing for single row inserted. */$stmt= db2_exec($conn, $insertTable);$stmt= db2_exec($conn, $guetIdentity);$row= db2_fetch_assoc($stmt);$ret= $row['LASTID'];
if($ret) {
echo"Last Insert ID is : " .$ret."\n";
} else {
echo "No Last insert ID.\n";
}
db2_close($conn);
}
else {
echo"Connection failed.";
}
?>
