![]() This guide addresses ODBC which OpenOffice uses to attach to databases and SQLite, in particular. Using the experimental SDBC SQLite driver.Via ODBC (Linux and Windows) which allows any application supporting this standard to reach a SQLite database.Via the SQLite PHP module or, if you have, PHP version 5 internally to a SQLite database.Via an in-line program (sqlite: available under Linux and Windows) that makes it possible to create and to manage the files of data bases.Via a C/C++ Linux library or Windows DLL.Plus it is fast (twice as much as PostgreSQL and MySQL for most operations) and has a small memory footprint.ĭata management can be achieved in the following ways: Machines with different byte orders and databases can be up to 2 terabytes (2 41 bytes) in size. Otherīenefits are: database access requires no database server, database files can be freely shared between Unlike PostgreSQL and MySQL, SQLite stores a whole data base with all its tables a single file. SQLite is a basic database engine that implements most of the features of SQL92. This Tutorial should guide you through the steps to connect OpenOffice to a SQLite database file. OpenOffice Base provides functions to connect to other databases than the default HSQL database. 5 Working on the database with OpenOffice.4 Connecting OpenOffice to a SQLite database.Slow Chat with the Microsoft Visual Basic team.Universal Windows Platform and Modern Windows Experience.Quick Navigation Visual Basic 6 and Earlier Top The reason I went there is that this error is also often seen when using the creaky old ODBC Desktop Drivers to interact with Text files, Excel worksheet ranges, etc. Or you might be able to redefine the table from scratch specifying variable length text fields. You might even be forced to explicitly NUL-pad the data. Clunky ODBC Drivers often struggle with coercion from Variant data to "database data" and may have imperfect logic to deal with fixed-length text fields. is it possible that you have inadvertantly changed the data type here?Įven if the field in the table is "text" of some sort it might be required to be space-padded out to a fixed length for example. Thus a lot of people end up relying on one of several very possibly "iffy" free ODBC Drivers. Using a high quality commercial SQLite OLEDB Provider cleans this up a lot and raises the odds of success, but there are no good free ones and Microsoft has never produced one. Anywhere along the line miscommunication can exist. ADO must talk to Microsoft OLE DB Provider for ODBC Drivers, which then tries to talk to this ODBC Driver, which is talking to SQLite code, which ultimately talks to raw disk. The SQLite ODBC Drivers are just the middle of a long chain of software impedance mismatches from ADO down to the underlying disk data. ![]() For something with locking as primitive as SQLite though I'm not sure anything is safe except to only allow one connection to be opened other than strictly read-only.īut set that possibility aside. That's the way you detect a deleted record when trying to update it. For a fuller-featured DBMS like even Jet, this is probably a normal exception to encounter when using adLockOptimistic. ![]() ![]() One is that some other connection has deleted the row before you try to update it. I can think of at least two possibilities.
