Microsoft Access Jdbc Driver Download Install Update
Because it is a pure Java implementation it runs on both Windows and non-Windows operating systems e. When dealing with large databases and using the default "memory" setting i.
Otherwise it will be necessary to set the driver's "memory" property to "false": If you are using Apache Maven to manage your dependencies recommended simply add the following to your pom. In order to open encrypted files you must use UCanAccess 2. Again, if you are using Maven, simply add this extra dependency: Note that the distribution comes with both a number of jUnit test cases package net.
Example which illustrate how UCanAccess may be used. If your project uses Maven you can simply include UCanAccess via the following coordinates:. Otherwise, see this Stack Overflow answer for details on how to configure your Java project. Establishing a UCanAccess connection Class. It should be set to a value close to the average size of OLE instances.
It doesn't have effect on referential integrity constraints i. Valid values for this parameter are: V, V, V, V If there are no active connections for the inactivityTimeout period in minutes HSQLDB will be temporarily shut down and any filesystem resources will be released. It will be restarted at the next connection. All resources memory and filesystem will be released at the closing of the connection. It should be used only with very large databases e. It gave null prior to version 3.
It avoids the data being reloaded when they aren't actually changed by the GUI. JackcessOpenerInterface interface in that case you need additional jar files in your classpath: The following example shows a custom integration with Jackcess Encrypt for opening a Money.
A SQL query looks like this: Single ' or double " quoted strings are supported. If you want to change this to a comma, use this flag like this: This schema file can be used by the BigQuery load tool. These can be imported into Google BigQuery using the bq load command like this: This is because many CSV readers are not able to read multi-line records. This flag preserves newline characters by enclosing them in double-quote characters.
Within the quotes, backslash escaping of the following special characters are supported: If we use quotes, we need to use two backslashes to represent one backslash of a Windows file path.
For example the following two commands are identical: Integration tested with UCanAccess 2. It doesn't work with previous UCanAccess versions. The commons-logging version in the recent UCanAccess distributions is the same as in NetBeans8 "commons-logging Setting the field Driver Class: Squirrel SQL web site: Fixed update queries having a parametric condition in the where clause e.
UcanloadDriver and the loader. They will be available, where possibile, using the "table " syntax, e. They will be available, where possibile, as stored precedures and via CallableStatement, e. About date values antecedent to the October 15, Gregorian: Fixed bug in "create table" where one or more column names are the same names of specific access types e.
UcanloadDriver" instead of the original one net. Upgrade to jackcess 2. They both have been reimplemented for this specific purpose.
Now UCanAccess can provide metadata with the correct capitalization and no more all in upper case. Changed escaping of column and table names containing special characters or out-of-rules e.
Supported all characterset with metadata they were supported in data but not always in metadata elements like column or table names Fixed isAutoIncrement and isCurrency ResultSetMetaData methods.
Implemented, for counters handling: Fixed memory leak in MemoryTimer. It had effect in some particular situations using the single connection mode if you're connecting to multiple db,in the case continous update by a different process, in the case of pooling on the db with intervals greater than the InactivityTimeout. Optimized reloading of db instances. It avoid the data to be reloaded when they aren't actually changed by the GUI.
In updatable ResultSet removed the constraint to set all columns before inserting new rows, even if they are null or autoincrement. It gave null in previous versions. Fixed bug that may have effect in the case of a naming conflict between a table in the opened database and a linked table in an external database. Allowed connecting to a corrupted database even if data violate an Unique, Not Null or Foreign Key constraint: Added parameter Lobscale, to optimize memory occupation when a relevant percent of memory occupation is for Ole Blob data.
It should be set to a value close to the average size of Ole instances. It allows skipping the creation of simple, untied to contraints, indexes. Fixed the error message logged when a db link metadata is broken for metadata corruption. Speeded database loading first connection time to a given database. Fixed bug that happened with table or column names containing an apostrophe or a quotation mark. Fixed bug in the switch function parsing. Deprecated and substituted parameter lockMdb: Fixed bug on table autoreferential constraint checks indipendence from storage order.
Supported exclamation point, as well as in the Access SQL syntax. Those keywords didn't have any effect on SQL, except for the particular case above. Fixed Connection setSavepoint String spn method setSavepoint only worked fine with no-arguments ; Fixed "Create table as select Implemented ErrorHandler for invalid characters sequences: Simply set this parameter to java.
Added orderJet function to allow compliance with Jet sorting logic that skip hyphen minus '-', en dash '—', em dash '—' and in the middle of a string: SQL error codes and states are those gotten from hsqldb you can handle them by using the constants in net.
Optimized the use of resources memory, filesystem. A later fix from the jackcess trunk to the 2. A table in an access database has a row count in its metadata saved the database , and this issue was due to a misalignment between row count in the metadata and the real number of table rows. So, it has been fixed in UCanAccess 2.
Strongly improved the UCanAccess behaviour in the case of multiple processes concurrency. Added connection parameter columnOrder to allow to use, in your SQL, the "display" order "data" order is still the default.
Once a column order has been setted on the first connection to a given database, the column order setting will be the same for all the following connections to that database, in the whole VM life. Allowed special characters and blank spaces in DDL. Column and table names, in this specific case, are not more escaped in the persisted table definition on the access file, but just in the mirror hsqldb database.
Allowed filtering on complex type columns version, attachment, multi-value. You can do that through one of the following functions: Added support to PreparedStatement. You still need to escape it using square brackets, to avoid ambiguity e. Notice that the user keyword, in general, refers to the database user.
Fixed bug that could have effect, in the previous versions, on delete and update statements, when a SQL keyword is used as table name. Also notice that calculated fields values are currently "calculated on fly" that's, for the moment, just a simulation and they aren't read from the database through jackcess.
As result, elaborating the expressions that depend on the Regional Settings e. Treated some more "special characters" e. Nevertheless keep in mind that this kind of calls forces a parsing operation, with a result which depend on the regional settings locale , so you had better use the delimiters and thus pass a date value instead of a character string. Solved residual bug on boolean type management. Introduced implementation of calculated fields. Fixed bug on working mode. Fix bug on Int function: Driver version read directly from the manifest file Package.
