H2數據庫。 使用html值更新CLOB字段時出錯
[英]H2 database. Error update CLOB field with html value
問題描述
我使用以下代碼更新CLOB字段。
final static String PAGE_BODY_UPDATE = "update BODYCONTENT set body = ? where bodycontentid = ?";
private static void updatePageContent(int pageID, String body) {
Connection conn = getConnection();
PreparedStatement st = conn.prepareStatement(PAGE_BODY_UPDATE);
st.setInt(1, pageID);
Clob myclob = conn.createClob();
myclob.setString(1, body);
st.setClob(2, myclob);
st.executeUpdate();
}
但這會引發錯誤。

我嘗試使用這樣的簡單html
"<html><head></head><body></body></html>"
但是我仍然有一個錯誤。 如何將html值上傳到CLOB字段？ 多謝回答！

你把你的參數顛倒了
嘗試
Clob myclob = conn.createClob();
myclob.setString(1, body);
st.setClob(1, myclob);
st.setInt(2, pageID);
