MySQL 8.3 Release Notes
A component service provides access to query attributes (see Section 11.6, “Query Attributes”). The query_attributes component uses this service to provide access to query attributes within SQL statements.
-
Purpose: Implements the
mysql_query_attribute_string()function that takes an attribute name argument and returns the attribute value as a string, orNULLif the attribute does not exist. -
URN:
file://component_query_attributes
Developers who wish to incorporate the same query-attribute component service used by query_attributes should consult the mysql_query_attributes.h file in a MySQL source distribution.
