XMLTYPE 插入超过4000的字符串

引用; http://steveracanovic.blogspot.com/2011/01/inserting-large-xmltype.html

When inserting large XMLTYPE, I am left with the following error:


java.sql.SQLException: ORA-01461: can bind a LONG value only for insert into a LONG column  at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:113) at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:331) at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:288) at oracle.jdbc.driver.T4C8Oall.receive(T4C8Oall.java:754) at oracle.jdbc.driver.T4CPreparedStatement.doOall8(T4CPreparedStatement.java:219) at oracle.jdbc.driver.T4CPreparedStatement.executeForRows(T4CPreparedStatement.java:972) at oracle.jdbc.driver.OracleStatement.doExecuteWithTimeout(OracleStatement.java:1192) at oracle.jdbc.driver.OraclePreparedStatement.executeInternal(OraclePreparedStatement.java:3415) at oracle.jdbc.driver.OraclePreparedStatement.executeQuery(OraclePreparedStatement.java:3460) at InsertXML.insertXMLType(InsertXML.java:47) at InsertXML.main(InsertXML.java:93)
I found 2 ways to get around this problem.

1. XMLType are opaque types, so I should be using oracle.xdb.XMLType. So my code should look something like:

XMLType xml; byte[] byteBuffer = xmlDetails.toString().getBytes(); InputStream is = new ByteArrayInputStream(byteBuffer); xml = XMLType.createXML(connection,is);  pstmt.setObject(1,xml);

2. In Oracle JDBC 11.2.0.2. (Not implemented in 11.2.0.1) and using JDK 1.6 (utilising JDBC 4.0) we can use SQLXML Type - java.sql.SQLXML

So the code should look something like:

SQLXML x = conn.createSQLXML(); x.setString(xmlDetails.toString()); pstmt.setSQLXML(1, x);

The second option here is preferred and moving forward.
