<para>
|
|
<function>oci_define_by_name</function> 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.
|
|
<function>oci_define_by_name</function> expects
|
|
the <parameter>column_name</parameter> to be in uppercase. If you
|
|
define a variable that doesn't exists in your select statement, no
|
|
error will be issued.

<para>
|
|
If you need to define an abstract datatype (LOB/ROWID/BFILE) you
|
|
must allocate it first using
|
|
<function>oci_new_descriptor</function>. See also the
|
|
<function>oci_bind_by_name</function> function.

<note>
|

<para>
|
|
In PHP versions before 5.0.0 you must use <function>ocidefinebyname</function> instead.
|
|
This name still can be used, it was left as alias of
|
|
<function>oci_define_by_name</function> for downwards compatability.
|
|
This, however, is deprecated and not recommended.
