2.22 (2020-10-16)¶

• New --encoding option for processing CSV and TSV files that use a non-utf-8 encoding, for both the insert and update commands. (#182)
• The --load-extension option is now available to many more commands. (#137)
• --load-extension=spatialite can be used to load SpatiaLite from common installation locations, if it is available. (#136)
• Tests now also run against Python 3.9. (#184)
• Passing pk=['id'] now has the same effect as passing pk='id'. (#181)

2.21 (2020-09-24)¶

• table.extract() and sqlite-utilsextract now apply much, much faster - one example operation reduced from twelve minutes to just four seconds! (#172)
• sqlite-utilsextract no longer shows a progress bar, because it's fast enough not to need one.
• New column_order= option for table.transform() which can be used to alter the order of columns in a table. (#175)
• sqlite-utilstransform--column-order= option (with a -o shortcut) for changing column order. (#176)
• The table.transform(drop_foreign_keys=) parameter and the sqlite-utilstransform--drop-foreign-key option have changed. They now accept just the name of the column rather than requiring all three of the column, other table and other column. This is technically a backwards-incompatible change but I chose not to bump the major version number because the transform feature is so new. (#177)
• The table .disable_fts(), .rebuild_fts(), .delete(), .delete_where() and .add_missing_columns() methods all now returnself, which means they can be chained together with other table operations.

2.20 (2020-09-22)¶

Newblue dj suite not installed. This release introduces two key new capabilities: transform (#114) and extract (#42).

Transform¶

Propresenter 6 5 3. SQLite's ALTER TABLE has several documented limitations. The table.transform() Python method and sqlite-utilstransform CLI command work around these limitations using a pattern where a new table with the desired structure is created, data is copied over to it and the old table is then dropped and replaced by the new one.

You can use these tools to change column types, rename columns, drop columns, add and remove NOTNULL and defaults, remove foreign key constraints and more. See the transforming tables (CLI) and transforming tables (Python library) documentation for full details of how to use them.

Extract¶

Sometimes a database table - especially one imported from a CSV file - will contain duplicate data. A Trees table may include a Species column with only a few dozen unique values, when the table itself contains thousands of rows.

The table.extract() method and sqlite-utilsextract commands can extract a column - or multiple columns - out into a separate lookup table, and set up a foreign key relationship from the original table.

The Python library extract() documentation describes how extraction works in detail, and Extracting columns into a separate table https://wars-torrent-how-do-i-control-alt-delete-on-a-mac.peatix.com. in the CLI documentation includes a detailed example.

Other changes¶

• The @db.register_function decorator can be used to quickly register Python functions as custom SQL functions, see Registering custom SQL functions. (#162)
• The table.rows_where() method now accepts an optional select= argument for specifying which columns should be selected, see Listing rows.

2.19 (2020-09-20)¶

• New sqlite-utilsadd-foreign-keys command for Adding multiple foreign keys at once. (#157)
• New table.enable_fts(.,replace=True) argument for replacing an existing FTS table with a new configuration. (#160)
• New table.add_foreign_key(.,ignore=True) argument for ignoring a foreign key if it already exists. (#112)

2.18 (2020-09-08)¶

• table.rebuild_fts() method for rebuilding a FTS index, see Rebuilding a full-text search table. (#155)
• sqlite-utilsrebuild-ftsdata.db command for rebuilding FTS indexes across all tables, or just specific tables. (#155)
• table.optimize() method no longer deletes junk rows from the *_fts_docsize table. This was added in 2.17 but it turns out running table.rebuild_fts() is a better solution to this problem.
• Fixed a bug where rows with additional columns that are inserted after the first batch of records could cause an error due to breaking SQLite's maximum number of parameters. Thanks, Simon Wiles. (#145)

2.17 (2020-09-07)¶

This release handles a bug where replacing rows in FTS tables could result in growing numbers of unneccessary rows in the associated *_fts_docsize table. (#149)

• New db.enable_wal() and db.disable_wal() methods for enabling and disabling Write-Ahead Logging for a database file - see WAL mode in the Python API documentation.
• Also sqlite-utilsenable-walfile.db and sqlite-utilsdisable-walfile.db commands for doing the same thing on the command-line, see WAL mode (CLI). (#132)

2.14 (2020-08-01)¶

• The insert-files command can now read from standard input: catdog.jpg|sqlite-utilsinsert-filesdogs.dbpics---name=dog.jpg. (#127)
• You can now specify a full-text search tokenizer using the new tokenize= parameter to enable_fts(). This means you can enable Porter stemming on a table by running db['articles'].enable_fts(['headline','body'],tokenize='porter'). (#130)
• You can also set a custom tokenizer using the sqlite-utils enable-fts CLI command, via the new --tokenize option.

2.13 (2020-07-29)¶

• --raw option to sqlite-utilsquery - for outputting just a single raw column value - see Returning raw data from a query, such as binary content. (#123)
• JSON output now encodes BLOB values as special base64 obects - see Running queries and returning JSON. (#125)
• The same format of JSON base64 objects can now be used to insert binary data - see Inserting JSON data. (#126)
• The sqlite-utilsquery command can now accept named parameters, e.g. sqlite-utils:memory:'select:num*:num2'-pnum5-pnum26 - see Running queries and returning JSON. (#124)

2.2.1 (2020-02-06)¶

Fixed a bug where .upsert(.,hash_id='pk') threw an error (#84).

2.2 (2020-02-01)¶

2.0 (2019-12-29)¶

Sqlpro For Sqlite Windows

This release changes the behaviour of upsert. It's a breaking change, hence 2.0.

The upsert command-line utility and the .upsert() and .upsert_all() Python API methods have had their behaviour altered. They used to completely replace the affected records: now, they update the specified values on existing records but leave other columns unaffected.

See Upserting data using the Python API and Upserting data using the CLI for full details.

If you want the old behaviour - where records were completely replaced - you can use $sqlite-utilsinsert.--replace on the command-line and .insert(.,replace=True) and .insert_all(.,replace=True) in the Python API. See Insert-replacing data using the Python API and Insert-replacing data using the CLI for more.

For full background on this change, see issue #66.

1.12.1 (2019-11-06)¶

Sqlpro For Mssql

• Fixed error thrown when .insert_all() and .upsert_all() were called with empty lists (#52)

You can use these tools to change column types, rename columns, drop columns, add and remove NOTNULL and defaults, remove foreign key constraints and more. See the transforming tables (CLI) and transforming tables (Python library) documentation for full details of how to use them.

1.0 (2019-05-24)¶

• Option to automatically add new columns if you attempt to insert or upsert data with extra fields:

  sqlite-utilsinsert.--alter - see Adding columns automatically with the sqlite-utils CLI

• New --json-cols option for outputting nested JSON, see Nested JSON values

0.14 (2019-02-24)¶

0.13 (2019-02-23)¶

• New --table and --fmt options can be used to output query results in a variety of visual table formats, see Running queries and outputting a table
• New hash_id= argument can now be used for Setting an ID based on the hash of the row contents
• Can now derive correct column types for numpy int, uint and float values
• table.last_id has been renamed to table.last_rowid
• table.last_pk now contains the last inserted primary key, if pk= was specified
• Prettier indentation in the CREATETABLE generated schemas

0.12 (2019-02-22)¶

• Added db[table].rows iterator - see Listing rows
• Replaced sqlite-utilsjson and sqlite-utilscsv with a new default subcommand called sqlite-utilsquery which defaults to JSON and takes formatting options --nl, --csv and --no-headers - see Running queries and returning JSON and Running queries and returning CSV
• New sqlite-utilsrowsdata.dbname-of-table command, see Returning all rows in a table
• sqlite-utilstable command now takes options --counts and --columns plus the standard output format options, see Listing tables

0.11 (2019-02-07)¶

New commands for enabling FTS against a table and columns:

See Configuring full-text search.

0.10 (2019-02-06)¶

Handle datetime.date and datetime.time values.

New option for efficiently inserting rows from a CSV:

0.9 (2019-01-27)¶

Improved support for newline-delimited JSON.

sqlite-utilsinsert has two new command-line options:

• --nl means 'expect newline-delimited JSON'. This is an extremely efficient way of loading in large amounts of data, especially if you pipe it into standard input.
• --batch-size=1000 lets you increase the batch size (default is 100). A commit will be issued every X records. This also control how many initial records are considered when detecting the desired SQL table schema for the data.

In the Python API, the table.insert_all(.) Pictorial 3 0 6 – non destructive photo editors. method can now accept a generator as well as a list of objects. This will be efficiently used to populate the table no matter how many records are produced by the generator.

The Database() constructor can now accept a pathlib.Path object in addition to a string or an existing SQLite connection object.

0.8 (2019-01-25)¶

Two new commands: sqlite-utilscsv and sqlite-utilsjson

These commands execute a SQL query and return the results as CSV or JSON. See Running queries and returning CSV and Running queries and returning JSON for more details.

Sqlpro Sqlite

0.7 (2019-01-24)¶

This release implements the sqlite-utils command-line tool with a number of useful subcommands.

• sqlite-utilstablesdemo.db lists the tables in the database
• sqlite-utilstablesdemo.db--fts4 shows just the FTS4 tables
• sqlite-utilstablesdemo.db--fts5 shows just the FTS5 tables
• sqlite-utilsvacuumdemo.db runs VACUUM against the database
• sqlite-utilsoptimizedemo.db runs OPTIMIZE against all FTS tables, then VACUUM
• sqlite-utilsoptimizedemo.db--no-vacuum runs OPTIMIZE but skips VACUUM

The two most useful subcommands are upsert and insert, which allow you to ingest JSON files with one or more records in them, creating the corresponding table with the correct columns if it does not already exist. See Inserting JSON data for more details.

• sqlite-utilsinsertdemo.dbdogsdogs.json--pk=id inserts new records from dogs.json into the dogs table
• sqlite-utilsupsertdemo.dbdogsdogs.json--pk=id upserts records, replacing any records with duplicate primary keys

Wave arts panorama 5 89. One backwards incompatible change: the db['table'].table_names property is now a method:

• db['table'].table_names() returns a list of table names
• db['table'].table_names(fts4=True) returns a list of just the FTS4 tables
• db['table'].table_names(fts5=True) returns a list of just the FTS5 tables

A few other changes:

• Plenty of updated documentation, including full coverage of the new command-line tool
• Allow column names to be reserved words (use correct SQL escaping)
• Added automatic column support for bytes and datetime.datetime

0.6 (2018-08-12)¶

• .enable_fts() now takes optional argument fts_version, defaults to FTS5. Use FTS4 if the version of SQLite bundled with your Python does not support FTS5
• New optional column_order= argument to .insert() and friends for providing a partial or full desired order of the columns when a database table is created
• New documentation for .insert_all() and .upsert() and .upsert_all()

0.5 (2018-08-05)¶

• db.tables and db.table_names introspection properties
• db.indexes property for introspecting indexes
• table.create_index(columns,index_name) method
• db.create_view(name,sql) method
• Table methods can now be chained, plus added table.last_id for accessing the last inserted row ID

0.4 (2018-07-31)¶

• enable_fts(), populate_fts() and search() table methods
