DBMS_LOB包的使用 1. dbms_lob.append( dest_lob IN OUT NOCOPY BLOB, src_lob IN BLOB) dbms_lob.append( dest_lob IN OUT NOCOPY CLOB CHARACTER SET ANY_CS, src_lob IN CLOB CHRACTER SET dest_lob%CHARSET); 将源LOB变量的内容添加到目标LOB变量的尾部. 示例:dest_lob
在Oracle中,存储在LOB中数据称为LOB的值,如使用Select 对某一LOB字段进行选择,则返回的不是LOB的值,而是该LOB字段的定位器(可以理解为指向LOB值的指针).如执行如下的SQL语句: DELCARE AUDIO_INFO BLOB: BENGIN SELECT audio INTO AUDIO_INFO FROM view_sites_info WHERE site_id=100;
题目大意:给你$n,k$,求:$$\sum\limits_{i=0}^k\binom n i\pmod{2333}$$题解:令$p=2333,f(n,k)\equiv\sum\limits_{i=0}^k\binom n i\pmod p$$$\begin{align*}f(n,k)\equiv&\sum\limits_{i=0}^k\binom n i\pmod p\\ \equiv&\sum\limits_{i=0}^k\binom{\big\lfloor\frac np\big
