Question

私はsqlite3データベースに何百万もの行を持っています。
a）はすべての3つの例の検索が 1366221142,1374614902値列「ポイントは」を含む行を検索するための最良の方法は何

{1399808086,1366221142,1374614902,1374608759,1375598069,1375270116,1935207612,1914502332,1913478333,1930188205,1934563311,1942881023,1373508175,-778100129,-788765075,-788763091,-790856156,-790835404,-791756027,-795938489,-779165370,-778051210,-740437658,-749943514,-754136794,-770946570,1376606678,1380850053,1380854148,1381902468,1381971092,308228244,324940180,324948372,327078869,292409717,275550503,275554606,275547438,812554558,812489022,1894554398,1895733774,1895741966,1912515343,1943993629,1935471709,1918694493,1914490972,1913409788,1913475260,1913458860,1929778348,1900414380,1883651988 ... up to nearly 1'000 numbers, ending with } 

：単一の行の列「点」は次の例が含まれています、1374608759
（位置2、3及び上記コンテンツでは4つ）

B）（3又は2できるだけ又は1）上記3例の検索が

値Iは、インデックスとそれを試みたが、 LIKEと '％1366221142％'の検索は「永遠」になります。

実際に私はFTS5で試してみますが、新しい作成された仮想テーブルへのインポートは数日かかるようです。

他の可能性はありますか？
