weblogic下寫clob的方法

領測軟件測試網 寫CLOB的代碼片段：

String SqlStr = "update TextInfo set Content=empty_clob() where TextInfoKey=" + Integer.toString(textinfokey);
myConn.setAutoCommit(false);
java.sql.PreparedStatement pstmt = myConn.prepareStatement(SqlStr);
pstmt.executeUpdate();

SqlStr = "select Content from TextInfo where TextInfoKey=" + Integer.toString(textinfokey) + " for update";
java.sql.Statement st = myConn.createStatement();
java.sql.ResultSet rs = st.executeQuery(SqlStr);
java.sql.Clob clob ;
if (rs.next()) {
clob = rs.getClob("Content");
weblogic.jdbc.rmi.SerialOracleClob cast1 =(weblogic.jdbc.rmi.SerialOracleClob)clob;
weblogic.jdbc.rmi.internal.OracleTClobImpl cast2 =(weblogic.jdbc.rmi.internal.OracleTClobImpl)cast1.getTheRealClob();
CLOB myClob = (oracle.sql.CLOB)cast2.getTheRealClob();
java.io.Writer out=myClob.getCharacterOutputStream();
out.write(content);
out.flush();
out.close();

}
