mysql - 将数据加载到mysql LOAD DATA INFILE 困难

Question

我正在执行以下查询将数据加载到 MySQL 中。

LOAD DATA LOCAL INFILE '/Users/ramjiseetharaman/Desktop/UTA/CSE\ 5330\ -\ Database\ Systems/Projects/Project\ 1/DEPARTMENT.txt'
INTO TABLE DEPARTMENT
FIELDS TERMINATED BY ','
ENCLOSED BY "'"
LINES TERMINATED BY "\n";

我收到以下警告，

我想加载以下数据:

'Research', 5, '333445555', '22-MAY-1978'
'Administration', 4, '987654321', '01-JAN-1985'
'Headquarters', 1, '888665555', '19-JUN-1971'
'Software', 6, '111111100', '15-MAY-1999'
'Hardware', 7, '444444400', '15-MAY-1998'
'Sales', 8, '555555500', '01-JAN-1997'
'HR', 9, '112244668', '01-FEB-1989'
'Networking', 3, '110110110', '15-MAY-2009'
'QA', 11, '913323708', '2-FEB-2010'

我在查询中缺少什么？为什么 Manager_Ssn 未加载？如有任何帮助，我们将不胜感激。

Answer 1

更改:

• 由 ',' 终止的字段 由 由 ', ' 终止的字段。
• 设置Mgr_start_date 列的格式。

尝试:

文件:/path/to/file/DEPARTMENT.txt:

'Research', 5, '333445555', '22-MAY-1978'
'Administration', 4, '987654321', '01-JAN-1985'
'Headquarters', 1, '888665555', '19-JUN-1971'
'Software', 6, '111111100', '15-MAY-1999'
'Hardware', 7, '444444400', '15-MAY-1998'
'Sales', 8, '555555500', '01-JAN-1997'
'HR', 9, '112244668', '01-FEB-1989'
'Networking', 3, '110110110', '15-MAY-2009'
'QA', 11, '913323708', '2-FEB-2010'

MySQL 命令行:

mysql> CREATE TABLE IF NOT EXISTS `DEPARTMENT` (
    ->   `Dname` VARCHAR(255),
    ->   `Dnumber` TINYINT(4),
    ->   `Mgr_ssn` BIGINT(20),
    ->   `Mgr_start_date` DATE
    -> );
Query OK, 0 rows affected (0.00 sec)

mysql> LOAD DATA LOCAL INFILE '/path/to/file/DEPARTMENT.txt'
    ->   INTO TABLE DEPARTMENT
    ->   FIELDS TERMINATED BY ', '
    ->   ENCLOSED BY "'"
    ->   LINES TERMINATED BY "\n"
    ->   (`Dname`, `Dnumber`, `Mgr_ssn`, @`Mgr_start_date`)
    ->   SET `Mgr_start_date` = STR_TO_DATE(@`Mgr_start_date`, '%d-%M-%Y');
Query OK, 9 rows affected (0.00 sec)
Records: 9  Deleted: 0  Skipped: 0  Warnings: 0

mysql> SELECT

    -> FROM
