DBI 0.7-12 (2017-08-10)

DBI 0.7-11 (2017-08-08)

  • The default implementation of dbReadTable() now has row.names = FALSE as default and also supports row.names = NULL (#186).

DBI 0.7 (2017-06-17)

  • Import updated specs from DBItest.
  • The default implementation of dbGetQuery() now accepts an n argument and forwards it to dbFetch(). No warning about pending rows is issued anymore (#76).
  • Require R >= 3.0.0 (for slots argument of setClass()) (#169, @mvkorpel).

DBI 0.6-1 (2017-04-01)

  • Fix dbReadTable() for backends that do not provide their own implementation (#171).

DBI 0.6 (2017-03-08)

  • Interface changes
  • Interface enhancements
    • Removed valueClass = "logical" for those generics where the return value is meaningless, to allow backends to return invisibly (#135).
    • Avoiding using braces in the definitions of generics if possible, so that standard generics can be detected (#146).
    • Added default implementation for dbReadTable().
    • All standard generics are required to have an ellipsis (with test), for future extensibility. - Improved default implementation of dbQuoteString() and dbQuoteIdentifier() (#77).
    • Removed tryCatch() call in dbGetQuery() (#113).
  • Documentation improvements
    • Finalized first draft of DBI specification, now in a vignette.
    • Most methods now draw documentation from DBItest, only those where the behavior is not finally decided don’t do this yet yet.
    • Removed max.connections requirement from documentation (#56).
    • Improved dbBind() documentation and example (#136).
    • Change omegahat.org URL to omegahat.net, the particular document still doesn’t exist below the new domain.
  • Internal
    • Use roxygen2 inheritance to copy DBI specification to this package.
    • Use tic package for building documentation.
    • Use markdown in documentation.

DBI 0.5-1 (2016-09-09)

  • Documentation and example updates.

DBI 0.5 (2016-08-11, CRAN release)

  • Interface changes
    • dbDataType() maps character values to "TEXT" by default (#102).
    • The default implementation of dbQuoteString() doesn’t call encodeString() anymore: Neither SQLite nor Postgres understand e.g. \n in a string literal, and all of SQLite, Postgres, and MySQL accept an embedded newline (#121).
  • Interface enhancements
  • Documentation improvements:
    • One example per function (except functions scheduled for deprecation) (#67).
    • Consistent layout and identifier naming.
    • Better documentation of generics by adding links to the class and related generics in the “See also” section under “Other DBI… generics” (#130). S4 documentation is directed to a hidden page to unclutter documentation index (#59).
    • Fix two minor vignette typos (#124, @mdsumner).
    • Add package documentation.
    • Remove misleading parts in dbConnect() documentation (#118).
    • Remove misleading link in dbDataType() documentation.
    • Remove full stop from documentation titles.
    • New help topic “DBIspec” that contains the full DBI specification (currently work in progress) (#129).
    • HTML documentation generated by staticdocs is now uploaded to http://rstats-db.github.io/DBI for each build of the “production” branch (#131).
    • Further minor changes and fixes.
  • Internal
    • Use contains argument instead of representation() to denote base classes (#93).
    • Remove redundant declaration of transaction methods (#110, @bborgesr).

DBI 0.4-1 (2016-05-07, CRAN release)

  • The default show() implementations silently ignore all errors. Some DBI drivers (e.g., RPostgreSQL) might fail to implement dbIsValid() or the other methods used.

DBI 0.4 (2016-04-30)

  • New package maintainer: Kirill Müller.

  • dbGetInfo() gains a default method that extracts the information from dbGetStatement(), dbGetRowsAffected(), dbHasCompleted(), and dbGetRowCount(). This means that most drivers should no longer need to implement dbGetInfo() (which may be deprecated anyway at some point) (#55).

  • dbDataType() and dbQuoteString() are now properly exported.

  • The default implementation for dbDataType() (powered by dbiDataType()) now also supports difftime and AsIs objects and lists of raw (#70).

  • Default dbGetQuery() method now always calls dbFetch(), in a tryCatch() block.

  • New generic dbBind() for binding values to a parameterised query.

  • DBI gains a number of SQL generation functions. These make it easier to write backends by implementing common operations that are slightly tricky to do absolutely correctly.

  • dbiCheckCompliance() has been removed, the functionality is now available in the DBItest package (#80).

  • Added default show() methods for driver, connection and results.

  • New concrete ANSIConnection class and ANSI() function to generate a dummy ANSI compliant connection useful for testing.

  • Default dbQuoteString() and dbQuoteIdentifer() methods now use encodeString() so that special characters like \n are correctly escaped. dbQuoteString() converts NA to (unquoted) NULL.

  • The initial DBI proposal and DBI version 1 specification are now included as a vignette. These are there mostly for historical interest.

  • The new DBItest package is described in the vignette.

  • Deprecated print.list.pairs().

  • Removed unused dbi_dep().

Version 0.3.1

Version 0.3.0

New and enhanced generics

New default methods

Deprecated features

  • The following functions are soft-deprecated. They are going away, and developers who use the DBI should begin preparing. The formal deprecation process will begin in July 2015, where these function will emit warnings on use.

  • dbGetDBIVersion() is deprecated since it’s now just a thin wrapper around packageVersion("DBI").

  • dbSetDataMappings() (#9) and dbCallProc() (#7) are deprecated as no implementations were ever provided.

Other improvements

  • dbiCheckCompliance() makes it easier for implementors to check that their package is in compliance with the DBI specification.

  • All examples now use the RSQLite package so that you can easily try out the code samples (#4).

  • dbDriver() gains a more effective search mechanism that doesn’t rely on packages being loaded (#1).

  • DBI has been converted to use roxygen2 for documentation, and now most functions have their own documentation files. I would love your feedback on how we could make the documentation better!

Version 0.2-7

  • Trivial changes (updated package fields, daj)

Version 0.2-6

  • Removed deprecated \synopsis in some Rd files (thanks to Prof. Ripley)

Version 0.2-5

  • Code cleanups contributed by Matthias Burger: avoid partial argument name matching and use TRUE/FALSE, not T/F.

  • Change behavior of make.db.names.default to quote SQL keywords if allow.keywords is FALSE. Previously, SQL keywords would be name mangled with underscores and a digit. Now they are quoted using ’“’.

Version 0.2-4

  • Changed license from GPL to LPGL

  • Fixed a trivial typo in documentation

Version 0.1-10

  • Fixed documentation typos.

Version 0.1-9

  • Trivial changes.

Version 0.1-8

  • A trivial change due to package.description() being deprecated in 1.9.0.

Version 0.1-7

  • Had to do a substantial re-formatting of the documentation due to incompatibilities introduced in 1.8.0 S4 method documentation. The contents were not changed (modulo fixing a few typos). Thanks to Kurt Hornik and John Chambers for their help.

Version 0.1-6

  • Trivial documentation changes (for R CMD check’s sake)

Version 0.1-5

  • Removed duplicated setGeneric(“dbSetDataMappings”)

Version 0.1-4

  • Removed the “valueClass” from some generic functions, namely, dbListConnections, dbListResults, dbGetException, dbGetQuery, and dbGetInfo. The reason is that methods for these generics could potentially return different classes of objects (e.g., the call dbGetInfo(res) could return a list of name-value pairs, while dbGetInfo(res, “statement”) could be a character vector).

  • Added 00Index to inst/doc

  • Added dbGetDBIVersion() (simple wrapper to package.description).

Version 0.1-3

  • ??? Minor changes?

Version 0.1-2

  • An implementation based on version 4 classes and methods.
  • Incorporated (mostly Tim Keitt’s) comments.
