将数组传递给oracle过程

这是一个如何做的例子。

以下脚本在数据库中设置表，类型和存储过程。该过程采用数组类型的参数，并将数组的每一行插入表中：

CREATE TABLE strings (s VARCHAr(4000));CREATE TYPE t_varchar2_array AS TABLE OF VARCHAr2(4000);/CREATE OR REPLACE PROCEDURE p_array_test(    p_strings      t_varchar2_array)ASBEGIN  FOR i IN 1..p_strings.COUNT  LOOP    INSERT INTO strings (s) VALUES (p_strings(i));  END LOOP;END;/

然后，Java代码演示如何将数组传递到此存储过程中：

import java.sql.*;import oracle.jdbc.*;import oracle.sql.*;public class ArrayTest {    public static void main(String[] args) throws Exception {        DriverManager.registerDriver(new OracleDriver());        Connection conn = DriverManager.getConnection( "jdbc:oracle:thin:@localhost:1521:xe", "user", "pass");        CallableStatement stmt = conn.prepareCall("BEGIN p_array_test(?); END;");        // The first parameter here should be the name of the array type.        // It's been capitalised here since I created it without using        // double quotes.        ArrayDescriptor arrDesc = ArrayDescriptor.createDescriptor("T_VARCHAR2_ARRAY", conn);        String[] data = { "one", "two", "three" };        Array array = new ARRAY(arrDesc, conn, data);        stmt.setArray(1, array);        stmt.execute();        conn.commit();        conn.close();    }}

如果先运行SQL脚本，然后运行Java类，然后查询表

strings

当您说“一个字符数组”时，我猜测您的意思是一个Java数组

char
