In such case, you can use integer, float-point, or string type data for the <parameter>value</parameter> argument. To update multiple number of attributes, you can disregard the <parameter>attr</parameter> argument, and set <parameter>value</parameter> argument with associative array data type. However, you cannot use the method for attribute of collection type.  You have to use APIs related to collection type (<function>cubrid_set_add</function>, <function>cubrid_set_drop</function>, etc) when you want to use <function>cubrid_put</function> on collection typed attribute.

+
