Updating Collection Members

You can update collection members by calling the UPDATE_MEMBER procedure and referencing the desired collection member by its sequence ID, for example:

APEX_COLLECTION.UPDATE_MEMBER (
    p_collection_name => collection name,
    p_seq             => member sequence number,
    p_c001            => member attribute 1,
    p_c002            => member attribute 2,
    p_c003            => member attribute 3,
    p_c004            => member attribute 4,
    p_c005            => member attribute 5,
    p_c006            => member attribute 6,
    p_c007            => member attribute 7,
    ...
    p_c050            => member attribute 50);
    p_clob001         => [CLOB member attribute 1],  

The UPDATE_MEMBER procedure replaces an entire collection member, not individual member attributes. This procedure causes an error if the named collection does not exist. For example:

Use the p_clob001 parameter for collection member attributes which exceed 4,000 characters.

If you want to update a single attribute of a collection member, use the UPDATE_MEMBER_ATTRIBUTE procedure, for example:

APEX_COLLECTION.UPDATE_MEMBER_ATTRIBUTE(
    p_collection_name       => collection_name,
    p_seq                   => member sequence number,
    p_attr_number           => member attribute number,
    p_attr_value            => member attribute value )

APEX_COLLECTION.UPDATE_MEMBER_ATTRIBUTE(
    p_collection_name        => collection_name,
    p_seq                    => member sequence number,
    p_clob_number            => CLOB member attribute number,
    p_clob_value             => CLOB member attribute value );

Calling the UPDATE_MEMBER_ATTRIBUTE procedure causes an error if the named collection does not exist.

Note that the only valid value for the p_clob_number parameter is 1.
