Access 97 tested through ODBC 1998.04.19, by monty@mysql.com
|
||
|
|
|
||
|
|
Access 97 has a bug when on executes a SELECT follwed very fast with a
|
||
|
|
DROP TABLE or a DROP INDEX command:
|
||
|
|
|
||
|
|
[Microsoft][ODBC Microsoft Access 97 Driver] The database engine couldn't lock table 'crash_q' because it's already in use by another person or process. (SQL-S1
|
||
|
|
000)(DBD: st_execute/SQLExecute err=-1)
|
||
|
|
|
||
|
|
Debugging SQL queries in Access 97 is terrible because most error messages
|
||
|
|
are of type:
|
||
|
|
|
||
|
|
Error: [Microsoft][ODBC Microsoft Access 97 Driver] Syntax error in CREATE TABLE statement. (SQL-37000)(DBD: st_prepare/SQLPrepare err=-1)
|
||
|
|
|
||
|
|
Which doesn't tell a thing!

Access 2000 tested through ODBC 2000.01.02, by monty@mysql.com
|
||
|
|
|
||
|
|
crash-me takes a LONG time to run under Access 2000.
|
||
|
|
|
||
|
|
The '1+NULL' and the 'OR and AND in WHERE' tests kills
|
||
|
|
Activestate Perl, build 521, DBI-DBC with an OUT OF MEMORY error.
|
||
|
|
The later test also kills perl/access with some internal errors.
|
||
|
|
To go around this one must run crash-me repeatedly with the --restart option.
|
||
|
|
|
||
|
|
Testing of the 'constant string size' (< 500K) takes a LOT of memory
|
||
|
|
in Access (at least 250M on My computer).
|
||
|
|
|
||
|
|
Testing of number of 'simple expressions' takes REALLY a lot of time
|
||
|
|
and memory; At some point I was up to 350M of used memory!
|
||
|
|
|
||
|
|
To fix the above, I modified crash-me to have lower max limits in the
|
||
|
|
above tests.
|
||
|
|
|
||
|
|
Benchmarks (under Win98):
|
||
|
|
|
||
|
|
Running the connect-test will take up all available memory and this
|
||
|
|
will not be freed even after quitting perl! There is probably some
|
||
|
|
bug in the Access connect code that eats memory!
