关于Oracle clob类型 数据的写入

2天的血泪史，终于给我弄出来了，一个大数据存储搞了2天（流下了菜鸟的泪水）

是哪个家伙，限制的sql语句的长度?，这样写会报字符串文字太长，因为oracle默认把字符串转换成varchar2类型,然而varchar2最大长度为4000，即使clob能够存储4000，也会导致数据无法成功插入。

String table = "";
String content = "大数据";
insert into "+table+" (NAME, CONTENT) values ('"+name+"', '"+content+"')

 网上有一种解法，但是我测试了并没有用，还是字符串文字太长

String name = "";
String table = "";
String content = "大数据字段";

String sql = "
declare
    content clob;
begin
  content := '大数据字段';
  insert into "+table+" (NAME,CONTENT) values ('"+name+"','"+content+"');
  update "+table+"set content = content  where NAME = '"+name+"';
end;
"

最终我试到了一种方法可以搞定

String table = "";
String name = "";
String content = "这个是大数据"
Writer outStream = null;
    	try {
			Class.forName("oracle.jdbc.driver.OracleDriver");
			Connection con = DriverManager.getConnection("jdbc:oracle:thin:@localhost:3306:orcl", "xx", "xx");
			con.setAutoCommit(false);
			Statement st = con.createStatement();
			st.executeUpdate("insert into "+table+"(NAME, CONTENT) values ('"+name+"', empty_clob())");
			ResultSet rs = st.executeQuery("select CONTENT from "+table+" where NAME= '"+name+"' for update");
			if (rs.next()){
				oracle.sql.CLOB clob = (oracle.sql.CLOB) rs.getClob("CONTENT");
				outStream = clob.getCharacterOutputStream();
				char[] c = content.toCharArray();
				outStream.write(c, 0, c.length);
			}
			outStream.flush();
			outStream.close();
			con.commit();
			con.close();
		} catch (Exception e) {
			e.printStackTrace();
		}

MySql天下第一！！！！??
