Field in data file exceeds maximum length " 看到这个错误后以为是字段值过小导致,将原来的varchar2(1000) 改到了varchar2(2000) 发现还是不可以,依旧报如上错误,于是怀疑是sqlldr自身存在某些限制了。 查了下,发现果然如此。 原来表中定义的字段REFUSE_REASON 虽然是VARCHAR2(1000); 但是用控制文件(CTL)中默认...
解决“field in data file exceed maximum length”错误的方法是在控制文件中明确指定字段的类型和长度。 在使用Oracle的SQL*Loader(sqlldr)工具进行数据导入时,如果遇到“field in data file exceed maximum length”错误,通常是因为控制文件(CTL)中对字段类型的默认处理与数据库表中的定义不一致导致的。以下是一些解...
检查报错日志提示:field in data file exceeds maximum length REMARK字段设置:varchar2(2000),报错的内容也没有超1000个字符 表中定义的字段 REMARK虽然是varchar2(2000),但控制文件(CTL)中默认为是char类型,所以,当该列数据长度超过255(char类型长度)时会提示出错 应该是sqlldr的限制,在ctl文件中配置 REMARK为:RE...
再测试varchar2(2000)类型,发现普通创建和online都能成功,因为varchar2(2000)字段最大可能长度是2000 关于索引key最大长度,在文档 ID 136158.1中给出了不同BLOCK SIZE的限制,你会发现8K BLOCK SIZE的maximum key length 文档中写的是3218而不是我们遇到的3215。这可能是由于文档是针对8i的版本,在新版本中这个值变...

character_maximum_length reports a extremely high value, which does not seem to relate to reality: this is the table structure: CREATE TABLE `multiqueue` ( `id` int(11) unsigned NOT NULL AUTO_INCREMENT, `uuid` varchar(36) NOT NULL, `draft_uuid` varchar(36) DEFAULT NULL COMMENT ...
Bytes per row8,060SQL Server supports row-overflow storage, which enables variable length columns to be pushed off-row. Only a 24-byte root is stored in the main record for variable length columns pushed out of row. For more information, seeLarge Row Support. ...
The maximum number of bytes in a clustered index key can't exceed 900. For a nonclustered index key, the maximum is 1,700 bytes.You can define a key using variable-length columns whose maximum sizes add up to more than the limit. However, the combined sizes of the data in those colum...
