SQLite

Package sqlite provides access to the SQLite library, version 3.

Package sqlite3 provides interface to SQLite3 databases. This works as a driver for database/sql. Installation Currently, go-sqlite3 supports the following data types. You can write your own extension module for sqlite3. For example, below is an extension for a Regexp matcher operation. It needs to be built as a so/dll shared library. And you need to register the extension module like below. Then, you can use this extension. You can hook and inject your code when the connection is established. database/sql doesn't provide a way to get native go-sqlite3 interfaces. So if you want, you need to set ConnectHook and get the SQLiteConn. If you want to register Go functions as SQLite extension functions, call RegisterFunction from ConnectHook. See the documentation of RegisterFunc for more details.

Package rqlite is a lightweight, distributed relational database built on SQLite. rqlite uses Raft to achieve consensus across the cluster of SQLite databases. It ensures that every change made to the database is made to a majority of underlying SQLite files, or none at all. rqlite gives you the functionality of a rock solid, fault-tolerant, replicated relational database, but with very easy installation, deployment, and operation. With it you've got a lightweight and reliable distributed store for relational data. You could use rqlite as part of a larger system, as a central store for some critical relational data, without having to run a heavier solution like MySQL.

Package sqlite implements gdb.Driver, which supports operations for database SQLite. Note: 1. It needs manually import: _ "github.com/glebarez/go-sqlite" 2. It does not support Save/Replace features.

Package dqlite implements a database/sql/driver with raft-based SQLite replication.

Package sqlite implements a database/sql driver for SQLite3. This driver requires a file: URI always be used to open a database. For details see https://sqlite.org/c3ref/open.html#urifilenames. If you want to do initial configuration of a connection, or enable tracing, use the Connector function: In-memory databases are popular for tests. Use the "memdb" VFS (*not* the legacy in-memory modes) to be compatible with the database/sql connection pool: Use a different dbname for each memory database opened. SQLite is flexible about type conversions, and so is this driver. Almost all "basic" Go types (int, float64, string) are accepted and directly mapped into SQLite, even if they are named Go types. The time.Time type is also accepted (described below). Values that implement encoding.TextMarshaler or json.Marshaler are stored in SQLite in their marshaled form. While SQLite3 has no strict time datatype, it does have a series of built-in functions that operate on timestamps that expect columns to be in one of many formats: https://sqlite.org/lang_datefunc.html When encoding a time.Time into one of SQLite's preferred formats, we use the shortest timestamp format that can accurately represent the time.Time. The supported formats are: If the time.Time is not UTC (strongly consider storing times in UTC!), we follow SQLite's norm of appending "[+-]HH:MM" to the above formats. It is common in SQLite to store "Unix time", seconds-since-epoch in an INTEGER column. This is understood by the date and time functions documented in the link above. If you want to do that, pass the result of time.Time.Unix to the driver. In general, time is hard to extract from SQLite as a time.Time. If a column is defined as DATE or DATETIME, then text data is parsed as TimeFormat and returned as a time.Time. Integer data is parsed as seconds since epoch and returned as a time.Time.

Package jet is a complete solution for efficient and high performance database access, consisting of type-safe SQL builder with code generation and automatic query result data mapping. Jet currently supports PostgreSQL, MySQL, MariaDB and SQLite. Future releases will add support for additional databases. Use the command bellow to add jet as a dependency into go.mod project: Jet generator can be installed in one of the following ways: (Go1.16+) Install jet generator using go install: go install github.com/go-jet/jet/v2/cmd/jet@latest Install jet generator to GOPATH/bin folder: cd $GOPATH/src/ && GO111MODULE=off go get -u github.com/go-jet/jet/cmd/jet Install jet generator into specific folder: git clone https://github.com/go-jet/jet.git cd jet && go build -o dir_path ./cmd/jet Make sure that the destination folder is added to the PATH environment variable. Jet requires already defined database schema(with tables, enums etc), so that jet generator can generate SQL Builder and Model files. File generation is very fast, and can be added as every pre-build step. Sample command: Before we can write SQL queries in Go, we need to import generated SQL builder and model types: To write postgres SQL queries we import: Then we can write the SQL query: Now we can run the statement and store the result into desired destination: We can print a statement to see SQL query and arguments sent to postgres server: Output: If we print destination as json, we'll get: Detail info about all statements, features and use cases can be found at project wiki page - https://github.com/go-jet/jet/wiki.

Package sqlite3 provides interface to SQLite3 databases. This works as a driver for database/sql. Installation Currently, go-sqlite3 supports the following data types. You can write your own extension module for sqlite3. For example, below is an extension for a Regexp matcher operation. It needs to be built as a so/dll shared library. And you need to register the extension module like below. Then, you can use this extension. You can hook and inject your code when the connection is established by setting ConnectHook to get the SQLiteConn. You can also use database/sql.Conn.Raw (Go >= 1.13): If you want to register Go functions as SQLite extension functions you can make a custom driver by calling RegisterFunction from ConnectHook. You can then use the custom driver by passing its name to sql.Open. See the documentation of RegisterFunc for more details.

Package sqlite provides a Go interface to SQLite 3. The semantics of this package are deliberately close to the SQLite3 C API, so it is helpful to be familiar with http://www.sqlite.org/c3ref/intro.html. An SQLite connection is represented by a *sqlite.Conn. Connections cannot be used concurrently. A typical Go program will create a pool of connections (using Open to create a *sqlite.Pool) so goroutines can borrow a connection while they need to talk to the database. This package assumes SQLite will be used concurrently by the process through several connections, so the build options for SQLite enable multi-threading and the shared cache: https://www.sqlite.org/sharedcache.html The implementation automatically handles shared cache locking, see the documentation on Stmt.Step for details. The optional SQLite3 compiled in are: FTS5, RTree, JSON1, Session This is not a database/sql driver. Statements are prepared with the Prepare and PrepareTransient methods. When using Prepare, statements are keyed inside a connection by the original query string used to create them. This means long-running high-performance code paths can write: After all the connections in a pool have been warmed up by passing through one of these Prepare calls, subsequent calls are simply a map lookup that returns an existing statement. The sqlite package supports the SQLite incremental I/O interface for streaming blob data into and out of the the database without loading the entire blob into a single []byte. (This is important when working either with very large blobs, or more commonly, a large number of moderate-sized blobs concurrently.) To write a blob, first use an INSERT statement to set the size of the blob and assign a rowid: Use BindZeroBlob or SetZeroBlob to set the size of myblob. Then you can open the blob with: Every connection can have a done channel associated with it using the SetInterrupt method. This is typically the channel returned by a context.Context Done method. For example, a timeout can be associated with a connection session: As database connections are long-lived, the SetInterrupt method can be called multiple times to reset the associated lifetime. When using pools, the shorthand for associating a context with a connection is: SQLite transactions have to be managed manually with this package by directly calling BEGIN / COMMIT / ROLLBACK or SAVEPOINT / RELEASE/ ROLLBACK. The sqliteutil has a Savepoint function that helps automate this. Using a Pool to execute SQL in a concurrent HTTP handler. For helper functions that make some kinds of statements easier to write see the sqliteutil package.
