|
||||
This package can be installed with the go get command:
|
||||
|
||||
go get github.com/mattn/go-sqlite3
|
||||
|
||||
|
||||
_go-sqlite3_ is *cgo* package.
|
||||
If you want to build your app using go-sqlite3, you need gcc.
|
||||
However, if you install _go-sqlite3_ with `go install github.com/mattn/go-sqlite3`, you don't need gcc to build your app anymore.

|

|

* Want to get time.Time with current locale
|
||||
|
||||
Use `loc=auto` in SQLite3 filename schema like `file:foo.db?loc=auto`.
|
||||
|
||||
* Can I use this in multiple routines concurrently?
|
||||
|
||||
Yes for readonly. But, No for writable. See [#50](https://github.com/mattn/go-sqlite3/issues/50), [#51](https://github.com/mattn/go-sqlite3/issues/51), [#209](https://github.com/mattn/go-sqlite3/issues/209).
|
||||
|
||||
* Why is it racy if I use a `sql.Open("sqlite3", ":memory:")` database?
|
||||
|
||||
Each connection to :memory: opens a brand new in-memory sql database, so if
|
||||
the stdlib's sql engine happens to open another connection and you've only
|
||||
specified ":memory:", that connection will see a brand new database. A
|
||||
workaround is to use "file::memory:?mode=memory&cache=shared". Every
|
||||
connection to this string will point to the same in-memory database. See
|
||||
[#204](https://github.com/mattn/go-sqlite3/issues/204) for more info.
