    <p>I am trying to save the JSON response of a website to the database. Latter I am accessing this JSON string for processing the data. But I am not able to parse it as JSON object. On analyzing I realize that the characters of strings needs to be escaped. Since I am saving the data as a string the data results which am getting back as a JSON data are not escaped in the database. Is there a way out how I can save the JSON data to the database.</p> <p>Example:</p> <pre><code> {"RULE":[{"replace":{"value":"","type":"text"},"match":{"value":"&lt;a [^&gt;]*&gt;&lt;img src="[^"]*WindowsLiveWriter/IconsfordifferentSocialBookmarkingSites[^&gt;]*&gt;\s*&lt;/a&gt;","type":"text"}},{"replace":{"value":"","type":"text"},"match":{"value":"&lt;a [^&gt;]*&gt;&lt;img src="[^"]*WindowsLiveWriter/IconsfordifferentSocialBookmarkingSites[^&gt;]*&gt;\s*&lt;/a&gt;","type":"text"}}]} </code></pre> <p>Want to save in database as (also getting the response as) i.e. the " and \ are escaped</p> <pre><code> {"RULE":[{"replace":{"value":"","type":"text"},"match":{"value":"&lt;a [^&gt;]*&gt;&lt;img src=\"[^\"]*WindowsLiveWriter/IconsfordifferentSocialBookmarkingSites[^&gt;]*&gt;\\s*&lt;/a&gt;","type":"text"}},{"replace":{"value":"","type":"text"},"match":{"value":"&lt;a [^&gt;]*&gt;&lt;img src=\"[^\"]*WindowsLiveWriter/IconsfordifferentSocialBookmarkingSites[^&gt;]*&gt;\\s*&lt;/a&gt;","type":"text"}}]} </code></pre> <p>Here is the code I have used to save the data in the database</p> <pre><code> // here the raw_data is the data from the website JSONObject jo = new JSONObject(raw_data); // Get the JSONObject value associated with the search result key. jo = jo.getJSONObject("pipe"); jo = jo.getJSONObject("definition"); String def=jo.toString(); JSONArray jo1=jo.getJSONArray("modules"); JSONArray jo2=jo.getJSONArray("wires"); /* * Write the contents in the data base * * */ def =def.replaceAll( "[']", "\\\\\'" ); //creates problem for strings with ' def =def.replaceAll( "&amp;", "%26" ); String tablename="PipesTable2"; System.out.println(def); database d=new database(); </code></pre>

    1. COthe website is sending you a string containing json. that string already has the escaping necessary. if it did not, the json you receive would not be readable. so what are you doing when you receive the data? it sounds like you are using some json library to unescape the data you receive. that same library can be used to escape it again.

    2. COIf you use the right DB ops you shouldn't need to escape the strings before storing them in the DB. Of course, you may need to escape your (strange) XML/HTML strings before using them as JSON values, but that's independent of the DB.

    3. CO@ andrew I have added the code I have wrote to save the data in the database. Actually I am converting the data which is JSON into a string (The reason was that I need to replace some of the contents like {} brackets with []) and then that converted string I am saving in the database

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
