對於 LOAD DATA INFILE 方法，如何識別 csv 文件中 sql 的行尾？ 嘗試由 '' '\r' '\r\n' 或 '\n' 終止的行......沒有任何效果

Question

我嘗試了多行終止配置 '\r' '\n' '\r\n'，但沒有任何效果。 我什至嘗試過 LINES TERMINATED BY ''，但這也不起作用，因為我不需要的列之一包含帶空格的文本。 還有一種方法可以跳過 CSV 數據文件中的某些列並使用此方法輸入我想要的 5 列而不控制 csv 文件嗎？

$sql = "LOAD DATA INFILE '$finalfile' INTO TABLE baa_load_actual_test
     FIELDS TERMINATED BY ',';
     LINES TERMINATED BY '\r\n';
     IGNORE 1 LINES;
     (INTERVALSTARTTIME_GMT, INTERVALENDTIME_GMT, LOAD_TYPE, OPR_DT, OPR_HR, 
             OPR_INTERVAL, MARKET_RUN_ID, TAC_AREA_NAME, LABEL, XML_DATA_ITEM, POS, MW, nexttolastcolumn, lastcolumn) ";

Answer 1

嘗試“CHAR(10)”而不是“/r/n”。

CHAR(10) 表示 SQL 中的 CARRIAGE RETURN（回車鍵）。
