SQLForeignKeys result-set question

Hi,

I'm using mysql-connector-odbc-3.51.12. I have two tables "market" and
"markettypes" and market has a foreign key on column type which is column
markettype_id in the table marketypes. When I run SQLForeignKeys I get:

PKTABLE_CAT:PKTABLE_SCHEM:PKTABLE_NAME:PKCOLUMN_NAME:FKTABLE_CAT:FKTABLE_SCHEM:F
KTABLE_NAME:FKCOLUMN_NAME:KEY_SEQ:UPDATE_RULE:DELETE_RULE:FK_NAME:PK_NAME:DEFERR
ABILITY:
bet::markettype:`markettype_id`:bet::market:`type`:1:1:1:NULL:NULL:7:

The colon is the column separator here. My question is, why is the
PKCOLUMN_NAME and FKCOLUMN_NAME contents created with single quotes around the
name.

If I do:

mysql> select * from INFORMATION_SCHEMA.KEY_COLUMN_USAGE where table_name =
'market' and referenced_table_name is not null;
+--------------------+-------------------+-----------------+---------------+----
----------+------------+-------------+------------------+-----------------------

bet          | market     | type        |                1 |                   
         1 | bet                     | markettype            | markettype_id   
      |
+--------------------+-------------------+-----------------+---------------+----
----------+------------+-------------+------------------+-----------------------
--------+-------------------------+-----------------------+---------------------
---+
1 row in set (0.00 sec)

The column names are without the single quotes.

I had a quick look in myodbc odbc driver code and could not spot anything doing
this.
