test dbi__null_test_tmp with MS Access Driver

Hi,

Only for completeness of the manual, I include the results of
perl_dbi_nulls_test.pl using MS Access

Thanks,


---------------------------------------------
Using dbi:ODBC:DRIVER={Microsoft Access Driver
(*.mdb)};DBQ=D:\Proyecto\STU-La Serena\SinDuplicados_Gustavo
01\Encuestas.mdb;PWD=Chiquita;, db version: 04.00.0000
=> Drop table 'dbi__null_test_tmp', if it already exists...
=> Create table 'dbi__null_test_tmp'...
=> Insert 4 rows into the table...
   Inserting values (1, 'Homer')
   Inserting values (2, NULL)
   Inserting values (3, 'Marge')
   Inserting values (4, NULL)

=> Testing clause style 0: WHERE mycol = ?...
   Selecting row with Marge
   Selecting rows with NULL

=>Your DBD driver doesn't support the 'rows' method very well.

=> WHERE clause style 0 returned incorrect results.
   Non-NULL test rows returned these row ids: 3
   The NULL test rows returned these row ids:

=> Testing clause style 1: WHERE NVL(mycol, '-') = NVL(?, '-')...
   Selecting row with Marge

=> Testing clause style 2: WHERE ISNULL(mycol, '-') = ISNULL(?, '-')...
   Selecting row with Marge

=> Testing clause style 3: WHERE DECODE(mycol, ?, 1, 0) = 1...
   Selecting row with Marge

=> Testing clause style 4: WHERE mycol = ? OR (mycol IS NULL AND ? IS
NULL)...
   Selecting row with Marge
   Selecting rows with NULL
=> WHERE clause style 4 is supported.

=> Testing clause style 5: WHERE mycol = ? OR (mycol IS NULL AND
SP_ISNULL(?) = 1)...
   Selecting row with Marge

=> Testing clause style 6: WHERE mycol = ? OR (mycol IS NULL AND ? = 1)...
   Selecting row with Marge
   Selecting rows with NULL
=> WHERE clause style 6 is supported.

------------------------------------------------------------------------
2 styles are supported:
Style 4: WHERE mycol = ? OR (mycol IS NULL AND ? IS NULL)
Style 6: WHERE mycol = ? OR (mycol IS NULL AND ? = 1)
