Oracle往列中插入html代码

  开发提了一个需求,需要往模板表中插入包含html代码的记录,表的ddl如下

create table WZ_SITEMSGTEMPLATE
(
  id              NUMBER(19) not null,
  templatecontent NCLOB,
  createtime      DATE,
  modeltype       NUMBER(10) default (1)  
)

  html代码如下:

  直接使用语句插入的时候,出现了“ORA-01756:引号内的字符串没有正确结束”的错误。

  我把代码截断一下,不用看起来那么费劲,重现一下错误

select  [<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>
    <style>
        body,
        div,
        p,
        a,
        img,
        span,
        h2 {
            margin: 0 ;
            padding: 0;]
  from dual;

  上面的代码,无论是在PL/SQL Developer里执行,还是在linux终端的sqlplus里执行,都是一样的错误。

  有2个情况需要在这里说明一下

    一、在linux终端的sqlplus里执行的时候,修改一下sqlterminator为非‘;‘的值,就能正常执行。

    二、我的PL/SQL Developer(版本:9.0.6)执行报错,但是旁边同事的PL/SQL Developer(版本:11.0.x)就执行成功,不确定是不是版本的问题,也可能是首选项或者其他配置的差异,至今没找到差异在哪里。

  google了一下,也没有搜索到答案,最终郑松华大师给了一个解决方法

select  [<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>
    <style>
        body,
        div,
        p,
        a,
        img,
        span,
        h2 {
            margin: 0 ||;|| 
            padding: 0;]
  from dual;

  原因是在oracle里,“;+换行”就是代表执行,所以就会提示上面的错误。但是让我疑惑的是,在字符串内的,为什么会执行?不到“‘”结束,也只是一段字符串而已。

  此方法一;

  补充:

  因为html代码太长,使用这种方法插入到列的时候,会提示“ORA-01489:字符串连接的结果过长”。其中原因是把这些代码当做字符串来拼接,最大的长度不能超过varchar2的长度,解决方法是:把代码分开转换成nclob类型,再进行拼接,完整例子如下:

select seq_wz_sitemsgtemplate.nextval,
to_nclob(<!DOCTYPE html>
