我宁愿将日期保留为时间戳格式。 如何将文件中的时间戳数据上传到mysql？

Answer 1

解决方案。感谢the_void的想法。

mysql> LOAD DATA INFILE '/data/mysql/tm.sql' INTO TABLE tm_table 
    -> (@var1) SET f=FROM_UNIXTIME(@var1); 
Query OK, 2 rows affected 
Records: 2 Deleted: 0 Skipped: 0 Warnings: 0 

mysql> select f from tm_table; 
+---------------------+ 
| f     | 
+---------------------+ 
| 2010-06-15 16:52:05 | 
| 2010-06-15 17:49:56 | 
+---------------------+ 
2 rows in set

您应该使用FROM_UNIXTIME功能，如：发现

#!/bin/bash 

FILENAME=$1 
TEMP=temp.txt 

for LINE in $(cat $FILENAME); do 
    echo "INSERT INTO tm_table(f) VALUES(FROM_UNIXTIME(`echo $LINE | tr -d '\r\n'`));" >> $TEMP 
done 

mysql -u XXX --password=XXX < $TEMP 

rm $TEMP
