如何将数据从CSV导入MySQL?
我有以下结构的csv文件:
A BA0011 U206 NAME 0000000000000149.00 000000.00 0000000000000118.93 S N N A BB0011 U206 NAME 0000000000000150.00 000000.00 0000000000000118.93 S N N
A BC0011 U206 NAME 0000000000000151.00 000000.00 0000000000000118.93 S N N
A BD0011 U206 NAME 0000000000000152.00 000000.00 0000000000000118.93 S N N
A BE0011 U206 NAME 0000000000000153.00 000000.00 0000000000000118.93 S N N
使用以下MySQL函数如何导入MySQL表的第一和第三列:
LOAD DATA INFILE 'data.csv' INTO TABLE tbl_name FIELDS TERMINATED BY \t' ENCLOSED BY '"'
LINES TERMINATED BY '\r\n'
IGNORE 1 LINES;
我为我的英语道歉!
提前致谢 !
回答:
您可以指定列,并将不需要的列标记为“ @dummy”。
LOAD DATA INFILE 'data.csv'INTO TABLE t1
(column1, @dummy, column2, @dummy, @dummy, @dummy, @dummy, @dummy, @dummy, @dummy)
FIELDS TERMINATED BY '\t' ENCLOSED BY
LINES TERMINATED BY '\r\n'
IGNORE 1 LINES;
替换t1
,column1
并且column2
只要你喜欢。要设置不在数据文件中的其他列,您可以这样做:
LOAD DATA INFILE 'data.csv'INTO TABLE t1
(column1, @dummy, column2, @dummy, @val, @dummy, @dummy, @dummy, @dummy, @dummy)
FIELDS TERMINATED BY '\t' ENCLOSED BY
LINES TERMINATED BY '\r\n'
IGNORE 1 LINES
SET column3 = "test", column4 = CURRENT_TIMESTAMP, column5 = @val/10;
作为进一步的参考,我建议您看一下MySQL参考。
