Working with CLOB data generally is same as working with BLOB data. The difference is in representation of Value property. For CLOB and NCLOB data types when you read from OracleLob.Value property, you get strings. The data is transparently decoded so you do not have to take care about ...
因为这种类型的字段,容量大(最多能容纳4GB的数据),且一个表中可以有多个这种类型的字段,很灵活,适用于数据量非常大的业务领域(如图象、档案等)。 LOB类型分为BLOB和CLOB两种:BLOB即二进制大型对象(Binary Large Object),适用于存贮非文本的字节流数据(如程序、图象、影音等)。 而CLOB,即字符型大型对象(Character...
BLOB :Variable-length binary large object string that can be up to 2GB (2,147,483,647) long. Primarily intended to hold non-traditional data, such as voice or mixed media. BLOB strings are not associated with a character set, as with FOR BIT DATA strings. BLOB:长度可变的二进制大对象字...
LOB类型分为BLOB和CLOB两种:BLOB即二进制大型对象(Binary Large Object),适用于存贮非文本的字节流数据(如程序、图象、影音等)。 而CLOB,即字符型大型对象(Character Large Object),则与字符集相关,适于存贮文本型的数据(如历史档案、大部头著作等)。 三、DB中使用CLOB类型字段 (一)、创建表(使用sql或者直接在PL...

In this release, support for operations over database links for LOB-based data types, such as CLOB, BLOB and XMLType, is available. This support enables operations on LOB-based data types across pluggable databases (PDBs) in an Oracle Multitenant environment. ...
Blob and Clob together are known as LOB(Large Object Type). I have been pretty much fascinated by these two data types. According to Oracle Docs, they are presented as follows : BLOB :Variable-length binary large object string that can be up to 2GB (2,147,483,647) long. Primarily inte...

1、SpringJdbcTemplate 操作 Clob 和 Blob 的通用类封装项目中使用 SpringJdbcTemplate 来操作数据库,简单方 便实用(根据项目需求选择技术 ),目前用到 Oracle10g 数据 库,由于其操作大文本使用 Clob 类型,故而研究了下 jdbctemplate 对 clob 和 Blob 的操作。jdbctemplate 对 clob 和 blob 的操作使用起来也很简...
