一言

MySQLの操作に慣れてからだと違和感凄い。

database一覧を表示しようと「show databases」叩いて表示されず、「そうだSQLiteだった」(.databasesか)となる。

SQLiteの操作は「.」始まりで、末尾には何も付けない(‘;’等不要)、一単語のみが多いと覚えれば直感的に操作できそう。

.exit 憶えとくと幸せになれると思う(sqliteなんもわからんときにexitとquitを試して駄目で諦めた黒歴史)。

構造を確認したいときは.schema

MySqlとかでテーブルの構造を確認したいときは「desc hogeTable」で指定していたが、SQLiteにはdescコマンドが無い。

SQLiteでテーブル構造を確認したい場合、「.schema hogeTable」で指定すると達成できる。因みに.schemaだけでも叩ける(全テーブルについての構造を表示させられる)。

sqlite> .schema users
CREATE TABLE IF NOT EXISTS 'users'(
  'id' INTEGER PRIMARY KEY AUTOINCREMENT,
  'password' TEXT NOT NULL,
  'name' TEXT NOT NULL,
  'administrator' BOOLEAN
);

sqlite> .schema users

CREATE TABLE IF NOT EXISTS 'users'(

'id' INTEGER PRIMARY KEY AUTOINCREMENT,

'password' TEXT NOT NULL,

'name' TEXT NOT NULL,

'administrator' BOOLEAN

);

sqlite> .schema
CREATE TABLE IF NOT EXISTS 'people'( 'id' INTEGER PRIMARY KEY AUTOINCREMENT, 'name' TEXT NOT NULL, 'mail' TEXT, 'age' INTEGER );
CREATE TABLE sqlite_sequence(name,seq);
CREATE TABLE IF NOT EXISTS 'users'(
  'id' INTEGER PRIMARY KEY AUTOINCREMENT,
  'password' TEXT NOT NULL,
  'name' TEXT NOT NULL,
  'administrator' BOOLEAN
);
