With ibmdb2i_create_index_option set to 1, creating an IBMDB2I table with a primary key should produce an additional index that uses EBCDIC hexadecimal sorting. However, this does not work. Adding indexes that are not primary keys does work. The ibmdb2i_create_index_option should be honoured when creating a table with a primary key. This patch adds code to the create() function to check for the value of the ibmdb2i_create_index_option variable and, when appropriate, to generate a *HEX-based shadow index in DB2 for the primary key. Previously this behavior was limited to secondary indexes. Additionally, this patch restricts the creation of shadow indexes to cases in which a non-*HEX sort sequence is used, as the documentation for ibmdb2i_create_index_option describes. Previously, the shadow index would in some cases be created even when the MySQL-specific index used *HEX sorting, leading to redundant indexes. Finally, the code used to generate the list of fields for indexes and the code used to generate the SQL statement for the shadow indexes has been refactored into individual functions.
