sqlldr加载文件,ORA-01722: invalid number解决
sqlldr加载文件,ORA-01722: invalid number解决
dos2unix 文件:将文件转为unix模式(内为文本的)
案例:
csv文件
sqlldr.control文件
LOAD DATA
INTO TABLE TOTO
FIELDS TERMINATED BY','
(BALL_No,MAIN_BALL_FREQUENCY,ADDITIONAL_NO_FREQUENCY)
sqlldr.data文件
通过ftp传上来的一个csv文件 /s01/sqlldr/toto.csv
sqlldr k24/k24control=sqlldr.control log=toto.log
问题:死活导入不进去,查看toto.log
Record 1: Rejected - Error on table K24.TOTO, column ADDITIONAL_NO_FREQUENCY.
ORA-01722: invalid number
每行都报这个错误
分析原因:被sqlldr导入的表,最后一列是数字型,,而我的csv文件中也是数字,报错非可用的数字,那我有理由怀疑在csv文件的每行最后都有一个回车符(windows中文本格式都有这个东西)
测试解决:
1、alter table toto modify ADDITIONAL_NO_FREQUENCY varchar2(20);
再次执行sqlldr 发现数据成功导入
这个结论再次验证了确实在全是数字的csv文本的最后,有不属于数字的东西,那就只有回车符了
2、dos2unixtoto.csv(这个命令会把windows中的文本转成linux格式的文本,其实就是把回车符给去掉)
3、将toto中的数据先行清除,然后将最后一列格式改回
alter table toto modify ADDITIONAL_NO_FREQUENCY number;
再次执行sqlldr。
select 表,发现已经导入成功。
改了一下control file
LOAD DATA
INFILE 'toto.csv'
BADFILE 'toto.bad'
APPEND
INTO TABLE toto
TRAILING NULLCOLS
(
BALL_NO INTEGER EXTERNAL TERMINATED BY ',',
MAIN_BALL_FREQUENCY INTEGER EXTERNAL TERMINATED BY ',',
ADDITIONAL_NO_FREQUENCY INTEGER EXTERNAL TERMINATED BY whitespace
)

Mastering the method of adding MySQL users is crucial for database administrators and developers because it ensures the security and access control of the database. 1) Create a new user using the CREATEUSER command, 2) Assign permissions through the GRANT command, 3) Use FLUSHPRIVILEGES to ensure permissions take effect, 4) Regularly audit and clean user accounts to maintain performance and security.

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.

When selecting MySQL's BLOB and TEXT data types, BLOB is suitable for storing binary data, and TEXT is suitable for storing text data. 1) BLOB is suitable for binary data such as pictures and audio, 2) TEXT is suitable for text data such as articles and comments. When choosing, data properties and performance optimization must be considered.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
