type NumberTable is table of number index by binary_integer;
create procedure TestNumberTable
(
p_NumTable IN NumberTable Default Cast(Null as NumberTable)
)
as
/* code body */
两个问题:
如何检查存储过程中的可为空性参数?
如何查找计数(*)[即存储过程中参数的行数?
答案 0 :(得分:0)
您无法使用二进制整数"创建"索引的UDT,您可以这样做:
create type NumberTable is table of number;
Q1:通过" nullability",你的意思是"它是否为空"?如果是这样,这将有效:
create procedure TestNumberTable
( p_NumTable IN NumberTable Default null)
as
if p_NumTable is null then
...
Q2:计数:
create procedure TestNumberTable
( p_NumTable IN NumberTable Default null)
as
dbms_output.put_line ('count is '||p_NumTable.count);
...
