Tim McCune Implement the majority of the missing standard functions: FormatCurrency, FormatDateTime, FormatNumber, FormatPercent, Val, DateAdd, DateDiff, DatePart, MonthName, WeekdayName, DDB, IPmt, PPmt, Rate, SLN, SYD, Format, Replace, StrConv. (Note that the internal API for the expr package has changed in an incompatible way. However, since the API is still experimental, this was deemed acceptable for a minor version.). Note that many of the financial functions were copied and adpated from the Apache POI and UCanAccess projects (which are both under the Apache License 2.0). Implement more type coercion methods for expressions. Add support for hex/oct integer strings. Add support for number strings with commas. Add support for coercing numeric String to a date/time value. Add support for date/time values with implicit (current) year. Ignore column validators for read-only dbs. This will avoid irrelevant failures when reading databases which have invalid column properties. Fix length in units calculation for Access 97 text fields. Implement support for optional expression evaluation. When enabled, expressions will be evaluated for default values, calculated fields, field validators, and record validators. Default values will now be respected when expression evaluation is enabled (currently disabled by default). Add some additional property keys and relevant enums for values. Create new usage map correctly when adding an index to an existing table. Expose the "ddl" attribute on properties. Set the attribute appropriately for known builtin properties.

Add some initial support for Table metadata modification. Columns and Indexes can now be added to an existing table (using ColumnBuilder.addToTable and IndexBuilder.addToTable respectively). Add the ability to create Relationships using RelationshipBuilder. With this support finally brings the ability to create foreign key indexes (aka integrity enforcement in Relationships). Fix missing column names in AppendQuery SQL strings. Add Database.getTableMetaData method to enable getting basic info about a Table (by name) without actually loading it. Allow null values in foreign key fields when enforcing referential integrity. Add support for cascade null on delete relationships. Add support for the required flag for an index. Throw a prettier exception when maxing out the row size during row creation. Add FileFormat.GENERIC_JET4 in order to support getting the file format for jet4 databases with no AccessVersion property (e.g. those created programmatically using ADOX).

Handle reading null calculated values. Fix handling of dateTimes before the access epoch. Load linked table info from system table when reading databases with unsupported sort orders. Allow optional direct insert/update of autonumber values. This is disabled by default, but can be selectively enabled per-jvm (using system property), per-database, and per-table. OpenHMS relicenses to Apache License, 2.0! Make ColumnBuilder.setMaxLength do the right thing regardless of column type. Handle input String boolean values. Added Database.isLinkedTable method to identify if the given Table is linked to the database. Added TableIterableBuilder for advanced Table iteration. This allows selectively including different table types when iterating the tables in a Database. Lowered the log level for certain warnings related to system tables which do not generally affect jackcess functionality. Added contextual information to many errors and warnings. Implement support for indexes on BINARY fields. Remove useless warning for fixed length columns lengths with longer length. Cleanup some other stuff related to copying existing columns in ColumnBuilder. Add newer sql type to access type mappings if the jvm supports them. Fix table name quoting for append and make table queries. Don't double quote already quoted identifiers. Better validation of identifier names (disallow invalid characters according to Access naming rules). Unicode compression support was not correct for all possibly compressed characters. Currency columns will now return an accurate scale and precision. IndexCursor can early exit when searching based on indexed values. Fix regression where empty memo values are returned as null. Add Cursor.findRow(RowId) for moving to a specific Table row using only the RowId. Add support for reading and writing calculated column values. Jackcess will not evaluate the actual expressions, but the column values can be written directly. Add the ability to set properties in DatabaseBuilder, TableBuilder, and ColumnBuilder. Add the ability to create tables with calculated fields. Add ColumnValidator interface which allows column values to be easily manipulated/validated as they are written into the database. Fix NullPointerException in RowImpl.toString() when value is null. Rework row add/update so that constraint violations do not leave behind partially written rows.

Add info to the Column to support MEMO columns which are HYPERLINKS. Add optional support for enforcing foreign-key constraints/cascading. This is disabled by default (for backwards compatibility), but can be controlled globally via a system property and/or on a per-Database basis using setEnforceForeignKeys() method. Add some more functionality to Joiner to facilitate integrity enforcement (hasRows and deleteRows). Added DatabaseBuilder for more convenient and flexible Database open/create. Added the MemFileChannel (and associated support in DatabaseBuilder) to enable working with Database files completely in memory. Fix some more edge cases in date/time conversions. Add osgi header information to the manifest. Add ImportUtil.toColumns to enable more advanced Table creation implementations. Fix NPE when running unit tests with db format MSISAM. Fix writing partial pages when CodecHandler is in use. Note, this fix involves a backwards incompatible change to the CodecHandler interface (Jackcess Encrypt 1.0.3 or later is compatible with this version of Jackcess). Add initial support for linked tables. Linked tables will now be loaded by the normal Database.getTable method. Linked tables can be created using the new Database.createLinkedTable method. Linked table resolution can be customized per Database by supplying a custom LinkResolver. Rename and refactor the Cursor find methods to improve usability. Add support for reading/writing complex column data (version history, attachments, multi-value columns).

Add support for reading properties blobs. Add methods for accessing database, summary, and user-defined properties from the Database. Add methods to Table and Column for accessing their respective properties. Add support for Access 2010, including new "General" sort order (support for super-long text index entries still needs work). Access expects a row to be at least big enough to hold all fixed values, even if they are null. Add Index.getReferencedIndex for retrieving the referenced Index for a foreign key index. Add support for writing all fixed length column types into variable length fields. More fixes related to reading and interpreting index information. Handle multiple logical indexes backed by the same index data. Interpret foreign key constraint information. Allow MSISAM files to be written (experimental). Add support for creating indexes when creating a new table. Normal indexes and primary key indexes are currently supported. Foreign key indexes are not yet supported. Add support for specifying a quote character on import from flat files. Add support for reading database password. Add support for plugging in implementations of various page encoding/decoding algorithms. See the <a href="https://jackcessencrypt.sourceforge.io/">Jackcess Encrypt</a> project for a CodecProvider implementation which supports a few of the Access encodings.

Share out-of-line long value pages in order to generate more compact database files. Add primitive support for writing unicode compressed text columns. Add compression code for possible future use; add compression unit tests. Fix writing of large memo/ole fields. Apparently Access does not like long value fields longer than 4076 bytes. Reduce maximum row size to what Access considers valid. Need to store auto-number values back into row so that indexes can be updated correctly. Access seems to limit data pages to a max of 255 rows. Added experimental support for "large" indexes. The current support is optional. It can be enabled via a variety of means, see the Database javadoc for more details. More fixes for index parsing. Believe index names are now correctly matched up with indexes. Simplify comparison algorithms for RowId and Index.Entry using type attributes.
