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...

For BLOB and CLOB data types only LOB locators (pointers to data) are stored in table columns; actual BLOB and CLOB data is stored in separate tablespace. This is the difference to the way that data of LONG or LONG RAW types is stored in database - tables hold their immediate values. ...

SELECT 'A' LIKE CONVERT(blob_col USING latin1) FROM tbl_name; 1. 要使用其他字符集, 只要把里面的 latin1 替换掉就行。为转换后的字符串指定特定的排序规则, 可以在 CONVERT() 函数调用后面跟上 COLLATE 从句, 正如 10.1.9.2 节“CONVERT() and CAST()” 中所描述的. 例如,使用 latin1_german1_ci...
