some times drivers have limits to the size of the string that you can use for querying/updating. If the value is too large, usually you'll have to stream the values in.

Probably you have code that tries to create a connection but fails, doesn't report an exception, and continues on trying to use that (null) connection variable. The reason for failing to create a connection would probably be because the configurations on the two machines are different. You can post your code if you want suggestions on how to improve it. |

Been a while since I used MS Access but there used to be an option for exclusive access. Make sure that box is not checked. Never seen that naming convention before but it's probably a new thing. Access used to create a corresponding .ldb file that contained the lock. Hope it helps. |

The correct format for a SQL delete (even in MS Access) is: DELETE FROM table WHERE conditional statement If you omit the where clause you will delete all rows. If you actually want to delete all rows, you should use a Truncate Table DDL command instead. [ December 14, 2007: Message edited by: Paul Campbell ] |

I've noticed that some of the archetypes for maven will automagically create a new database and table and run some dbunit tests. I would like to automate the creation of MSAccess databases.

Images are binary data, don't use CLOB. Use a BLOB. Create a binary field in the database and use PreparedStatement#setBinaryStream() to store it and ResultSet#getBinaryStream() to retrieve it. Not sure if that is supported by MSAccess as well as it isn't a decent database. Otherwise either upgrade to a decent RDBMS or store the images in the file system and save ... |

I suspect that your code will not work if someone else inserts in between the original insert and when your code finishes its loop. It looks like the @@identity variable exists in access per the following from microsofts site. I don't use access so you should look into this further. After an insert a query like 'select @@identity' will return the ... |
