BaseType Array type object. Note: Objects should always be created or deserialized using the ArrayType.Builder. This model distinguishes fields that are null because they are unset from fields that are explicitly set to null. This is done in the setter methods of the ArrayType.Builder, which...
在PL/SQL中,数组数据类型是VARRAY(variable array,即可变数组)。 定义VARRAY数据类型的语法如下: TYPE VARRAY_NAMEIS VARRAY(SIZE) OF ELEMENT_TYPE [NOT NULL]; 其中,varray_name是VARRAY数据类型的名称,size是正整数,表示可以容纳的成员的最大数量,每个成员的数据类型是element_typeo默认时,成员可以取空值,否则需...
