| 104 | <p><b>Description</b> Returns result for query as JSON. The response is a JSON object that contains some result metadata along with either an embedded result or an opaque handle that can be used to navigate to the result (see the decription of the <tt>mode</tt> parameter for more details).</p> |
| 105 | <p><b>Parameters</b></p> |
| 106 | <ul> |
| 107 | |
| 108 | <li><tt>statement</tt> - Specifies at least one valid SQL++ statement to run. The statements need to be urlencoded. Required.</li> |
| 109 | <li><tt>pretty</tt> - If the parameter <tt>pretty</tt> is given with the value <tt>true</tt>, the result will be indented. (Optional)</li> |
| 110 | <li><tt>client_context_id</tt> - A user-defined sequence of characters that the API receives and returns unchanged. This can be used e.g. to match individual requests, jobs, and responses. Another option could be to use it for groups of requests if an application decides to put e.g. an group identifier into that field to route groups of responses to a particular response processor.</li> |
| 111 | <li><tt>mode</tt> - Result delivery mode. Possible values are <tt>immediate</tt>, <tt>deferred</tt>, <tt>async</tt> (default: <tt>immediate</tt>). If the delivery mode is <tt>immediate</tt> the query result is returned with the response. If the delivery mode is <tt>deferred</tt> the response contains a handle to the <a href="#queryresult">result</a>. If the delivery mode is <tt>async</tt> the response contains a handle to the query’s <a href="#querystatus">status</a>.</li> |
| 112 | <li><tt>args</tt> - (SQL++ only) A JSON array where each item is a value of a <a href="sqlpp/manual.html#Parameter_references">positional query parameter</a></li> |
| 113 | <li><tt>$parameter_name</tt> - (SQL++ only) a JSON value of a <a href="sqlpp/manual.html#Parameter_references">named query parameter</a>.</li> |
