MS SQL では、以下の sql コマンドを使用して一括挿入を実行できます。
BULK INSERT dbo.TweetJSON
from ‘D:\file.txt’
with (CODEPAGE=’65001’, FORMATFILE=’D:\BIFormatFile.txt’
);
BIFormatFile の内容は次のとおりです。
9.0
1
1 SQLCHAR 0 8000 “\r\n” 1 [JSONData] “”
今、私はMySQLで同じことをしたいのですが、これがどのように機能し、どのクエリを使用するのか理解できないようです..
これまでのところ、私が考え出した行は次のとおりです。
LOAD DATA INFILE 'C:\File.txt'
INTO TABLE dbo.tweetjson
FIELDS TERMINATED BY '\r\n'
ただし、これらの MSSQL コードを MYSQL に変換するために必要なすべてのコードをまだ把握していません。助けてください..
file.txt の行の例:
