FAQ
|
||||
---
|
||||
|
||||
* Want to build go-sqlite3 with libsqlite3 on my linux.
|
||||
|
||||
Use `go build --tags "libsqlite3 linux"`
|
||||
|
||||
* Can't build go-sqlite3 on windows 64bit.
|
||||
|
||||
> Probably, you are using go 1.0, go1.0 has a problem when it comes to compiling/linking on windows 64bit.
|
||||
> See: https://github.com/mattn/go-sqlite3/issues/27
|
||||
|
||||
* Getting insert error while query is opened.
|
||||
|
||||
> You can pass some arguments into the connection string, for example, a URI.
|
||||
> See: https://github.com/mattn/go-sqlite3/issues/39
|
||||
|
||||
* Do you want cross compiling? mingw on Linux or Mac?
|
||||
|
||||
> See: https://github.com/mattn/go-sqlite3/issues/106
|
||||
> See also: http://www.limitlessfx.com/cross-compile-golang-app-for-windows-from-linux.html
|
||||
|
||||
* Want to get time.Time with current locale
|
||||
|
||||
Use `loc=auto` in SQLite3 filename schema like `file:foo.db?loc=auto`.

Currently, go-sqlite3 support following data types.
|
||||
|
||||
+------------------------------+
|
||||
|go | sqlite3 |
|
||||
|----------|-------------------|
|
||||
|nil | null |
|
||||
|int | integer |
|
||||
|int64 | integer |
|
||||
|float64 | float |
|
||||
|bool | integer |
|
||||
|[]byte | blob |
|
||||
|string | text |
|
||||
|time.Time | timestamp/datetime|
|
||||
+------------------------------+
|
||||
|
||||
SQLite3 Extension
|
||||
|
||||
You can write your own extension module for sqlite3. For example, below is a
|
||||
extension for Regexp matcher operation.
|
||||
|
||||
#include <pcre.h>
|
||||
#include <string.h>
|
||||
#include <stdio.h>
|
||||
#include <sqlite3ext.h>
|
||||
|
||||
SQLITE_EXTENSION_INIT1
|
||||
static void regexp_func(sqlite3_context *context, int argc, sqlite3_value **argv) {
|
||||
if (argc >= 2) {
|
||||
const char *target = (const char *)sqlite3_value_text(argv[1]);
|
||||
const char *pattern = (const char *)sqlite3_value_text(argv[0]);
|
||||
const char* errstr = NULL;
|
||||
int erroff = 0;
|
||||
int vec[500];
|
||||
int n, rc;
|
||||
pcre* re = pcre_compile(pattern, 0, &errstr, &erroff, NULL);
|
||||
rc = pcre_exec(re, NULL, target, strlen(target), 0, 0, vec, 500);
|
||||
if (rc <= 0) {
|
||||
sqlite3_result_error(context, errstr, 0);
|
||||
return;
|
||||
}
|
||||
sqlite3_result_int(context, 1);
|
||||
}
|
||||
}
|
||||
|
||||
#ifdef _WIN32
|
||||
__declspec(dllexport)
|
||||
#endif
|
||||
int sqlite3_extension_init(sqlite3 *db, char **errmsg,
|
||||
const sqlite3_api_routines *api) {
|
||||
SQLITE_EXTENSION_INIT2(api);
|
||||
return sqlite3_create_function(db, "regexp", 2, SQLITE_UTF8,
|
||||
(void*)db, regexp_func, NULL, NULL);
|
||||
}
|
||||
|
||||
It need to build as so/dll shared library. And you need to register
|
||||
extension module like below.
|
||||
|
||||
sql.Register("sqlite3_with_extensions",
|
||||
&sqlite3.SQLiteDriver{
|
||||
Extensions: []string{
|
||||
"sqlite3_mod_regexp",
|
||||
},
|
||||
})
|
||||
|
||||
Then, you can use this extension.
|
||||
|
||||
rows, err := db.Query("select text from mytable where name regexp '^golang'")
|
||||
|
||||
Connection Hook
|
||||
|
||||
You can hook and inject your codes when connection established. database/sql
|
||||
doesn't provide the way to get native go-sqlite3 interfaces. So if you want,
|
||||
you need to hook ConnectHook and get the SQLiteConn.
|
||||
|
||||
sql.Register("sqlite3_with_hook_example",
|
||||
&sqlite3.SQLiteDriver{
|
||||
ConnectHook: func(conn *sqlite3.SQLiteConn) error {
|
||||
sqlite3conn = append(sqlite3conn, conn)
|
||||
return nil
|
||||
},
|
||||
})
|
||||

||||
