Answer 1

找到解决方案。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 函数，如下所示：

#!/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
