java实现oracle传递array数组类型的参数

原理：

1.一维数组

A.单纯的一维数组的话，直接建立一个table类型就可以

TYPE TYPE_VARCHAR AS TABLE OF VARCHAR2(200);

2.多维数组

A.多维数组就要稍加修改了，如二维数组

TYPE TYPE_VARCHAR AS TABLE OF VARCHAR2(200);

TYPE TYPE_TABLE AS TABLE OF TYPE_VARCHAR;

3.java代码的实现

A。首先是connection的问题，connection必须是OracleConnection（java.sql包下的）

B。必须给Array添加一种数据定义（oracle.sql.ArrayDescriptor）

C。ARRAY必须是java.sql.Array

D。好了，开始定义ARRAY

arrDesc = ArrayDescriptor.createDescriptor("TYPE_TABLE", getNativeConnection(conn));
ARRAY arr = new ARRAY(arrDesc, getNativeConnection(conn), new Object[][]{{"test1","test2"},{"testA","testB"}});

从网上搜到为数不多的代码(仅供参考)
