oci_define_by_name() defines PHP variables for fetches
of SQL-Columns. Take into consideration that Oracle uses ALL-UPPERCASE column names,
whereby in your select you can also use lowercase.
oci_define_by_name() expects
the column_name to be in uppercase. If you
define a variable that doesn't exists in your select statement, no
error will be issued.
If you need to define an abstract datatype (LOB/ROWID/BFILE) you
must allocate it first using
oci_new_descriptor(). See also the
oci_bind_by_name() function.
Example 1. oci_define_by_name() example
<?php /* oci_define_by_name example - thies at thieso dot net (980219) */
$conn = oci_connect("scott", "tiger");
$stmt = oci_parse($conn, "SELECT empno, ename FROM emp");
Note:
In PHP versions before 5.0.0 you must use ocidefinebyname() instead.
This name still can be used, it was left as alias of
oci_define_by_name() for downwards compatability.
This, however, is deprecated and not recommended.
