    <p>I'm using Delphi XE2 with <code>DBXJSON</code> and I'm having trouble handling a JsonArray contained inside a String. The String I got is this:</p> <pre><code>"[ {DAT_INCL: \"2/3/2012 16:45:9\", NUM_ORDE: 1, NUM_ATND: 734, NUM_ACAO: 2, NUM_RESU: 3}, {DAT_INCL: \"2/3/2012 16:45:10\", NUM_ORDE: 2, NUM_ATND: 734, NUM_ACAO: 4, NUM_RESU: 5}, {DAT_INCL: \"2/3/2012 16:45:10\", NUM_ORDE: 3, NUM_ATND: 734, NUM_ACAO: 8, NUM_RESU: NULL} ]" </code></pre> <p><strong>Goddamn quotation marks.</strong></p> <p>No matter how hard I try, I can never get my hands on this array, no <code>ParseJSONValue</code> and no crazy type juggling could get the array out of this quotation-mark prison.</p> <p>Maybe one of you got the key?</p> <p>EDIT: This string is already the result of a bit of type conversion. In case anyone is interested in seeing how I extracted this string, maybe to find a better way to finally get the array out (he's really lonely and scared), here's how I did it:</p> <p>Originally, I had a two-pair <code>TJsonObject</code> named jObject</p> <pre><code>{ "id": 0, "data": "[{DAT_INCL: \"08/03/2012 10:07:08\", NUM_ORDE: 1, NUM_ATND: 1, NUM_ACAO: 2, NUM_RESU: 3}, {DAT_INCL: \"08/03/2012 10:07:09\", NUM_ORDE: 2, NUM_ATND: 1, NUM_ACAO: 4, NUM_RESU: 5}, {DAT_INCL: \"08/03/2012 10:07:09\", NUM_ORDE: 3, NUM_ATND: 1, NUM_ACAO: 8, NUM_RESU: NULL}]" } </code></pre> <p>I proceeded to extract the relevant <code>TJsonPair</code>, named jPair:</p> <pre><code>jPair := jObject.Get(1); </code></pre> <p>Which nets me this:</p> <pre><code>"data": "[{DAT_INCL: \"08/03/2012 10:07:08\", NUM_ORDE: 1, NUM_ATND: 1, NUM_ACAO: 2, NUM_RESU: 3}, {DAT_INCL: \"08/03/2012 10:07:09\", NUM_ORDE: 2, NUM_ATND: 1, NUM_ACAO: 4, NUM_RESU: 5}, {DAT_INCL: \"08/03/2012 10:07:09\", NUM_ORDE: 3, NUM_ATND: 1, NUM_ACAO: 8, NUM_RESU: NULL}]" </code></pre> <p>From that, I extracted the <code>String</code>, named sString</p> <pre><code>sString:= jPair.JsonValue.ToString; </code></pre> <p>Which nets me that string on the start of the question. And that is as good as it got, so far.</p>

    1. COwhy do you need `jPair.JsonValue.ToString`? use `jPair.JsonValue as TJsonArray` to get array

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.
