Mysql CSV加載infile

Question

我有一個包含9列的CSV文件，我有一個包含11列的MySQL表。

CSV文件如下所示：

col1, col2, col3, col4, col5, col6, col7, col8, col9

和MySQL表看起來像：

col1, col2, col3, col4, col5, col6, col7, col8, col9, col10, col11

我需要讓腳本忽略兩個錯誤的（但必需的）MySQL列。

導入中需要忽略的mysql列是：db_id＆nice_date =）

這是我到目前為止：

$sql = 'LOAD DATA LOCAL INFILE "../csvtemp/test.csv" 
        INTO TABLE sample 
            FIELDS TERMINATED BY "," 
            OPTIONALLY ENCLOSED BY """" 
            IGNORE 1 LINES'
;

Answer 1

$sql = 'LOAD DATA LOCAL INFILE "../csvtemp/test.csv" 
        INTO TABLE sample 
            FIELDS TERMINATED BY "," 
            OPTIONALLY ENCLOSED BY """" 
            IGNORE 1 LINES
            (col1, col2, col3, col4, col5, col6, col7, col8, col9)'
;

缺少的列將被賦予其DEFAULT值，否則您可以通過以下方式指定固定值：

$sql = 'LOAD DATA LOCAL INFILE "../csvtemp/test.csv" 
        INTO TABLE sample 
            FIELDS TERMINATED BY "," 
            OPTIONALLY ENCLOSED BY """" 
            IGNORE 1 LINES
            (col1, col2, col3, col4, col5, col6, col7, col8, col9)'
            SET col10 = 'abc', col11 = 'xyz'
;

Answer 2

看起來你可以使用LINES TERMINATED BY （可能使用PHP_EOL ）。

引用手冊頁：

如果某行不包含所有字段，則其余列將設置為其默認值。
