需求:以开发的存储过程为例,需要循环遍历时间范围拼接sql,将时间日期按列反转(pivot),如果时间太长(1年以上)sql语句(varchar2)就会超出范围报错,这时候就需要使用CLOB来存储拼接的sql。 PROCEDURE P_AND_CPT_RATIOOTH_APP_BAK2_N( V_APPIDS IN VARCHAR2, V_TYPE IN VARCHAR2, V_CHANNEL IN VARCHAR2, V_T...
含义是：Sets the size (in bytes) of the increments SQL*Plus uses to retrieve a CLOB, LONG, NCLOB or XMLType value.即sqlplus会按照这个参数的值来⼀段⼀段的获取上述类型的数据，直到达到long的值或者数据获取完毕。举例：数据有10个字节：0123456789 如果set longchunksize 2，那么显⽰出来的效果就...
