Question

我有以下查询

SELECT email_text INTO  v_result 
    FROM  test.record_notification 
    WHERE record_notification_id = p_recordnotification_id;

返回以下结果

[br /] [br /] [br /]记录ID：记录名称：标题ID：标题名称[br /] [ul] http：// localhost：8080 / myproject / ShowRecords.action？recordsVO.recordId = 3324＆amp; recordId = 3324＆amp; status = Record Requested＆gt; 3324：DEV：test contract：2448730：Titanic [/ ul]

但是我想添加＆＃34; [th]＆＃34; ＆＃34; [/日]＆＃34;在上面的结果中，最终字符串变为

[br /] [br /] [br /] [th]记录ID：记录名称：标题ID：标题名称[br /] [/ th] [th] http：// localhost：8080 / myproject / ShowRecords.action？recordsVO.recordId = 3324＆amp; recordId = 3324＆amp; status = Record Requested＆gt; 3324：DEV：test contract：2448730：Titanic [/ th]

请注意，可以有多个这样的记录。

请在PostgreSQL中建议一种方法

按

替换您的查询

SELECT '[br/] [br/] [br/]<th>' || replace(replace(email_text,'[br/]',''),'ul','th') INTO  v_result 
    FROM  test.record_notification 
    WHERE record_notification_id = p_recordnotification_id;

我假设你只有一个记录的问题感谢

如果您不担心 br ，那么就这样做

 SELECT '<th>' || replace(replace(email_text,'[br/]',''),'ul','th') INTO  v_result 
        FROM  test.record_notification 
        WHERE record_notification_id = p_recordnotification_id;

它将在99％的情况下工作

在PostgreSQL中的特定位置插入一个字符串
