								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.

						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								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!
