Create @myjson variable as JSON type (read more): SET @myjson = CAST('["A","B",{"id":1,"label":"C"}]' as JSON) ; SELECT some members! SELECT JSON_EXTRACT( @myjson , '$[1]' ) , JSON_EXTRACT( @myjson , '$[*].label') , JSON_EXTRACT( @...

Once your Kubernetes cluster is running and kubectl is configured you could run your first application with a few steps. This can be done using the imperative commands which doesn't need configuration files. In order to run an application you need to provide a deployment name (bootcamp), the contai...

XHTML Relation to HTML XHTML is simply the serialized version of HTML. XHTML was originally intended to clean up HTML markup to better improve standards support. Unfortunately the W3C's work on XHTML 2.0 was not intuitive and detracted from where the industry as a whole was headed with HTML5. XHTML...

The following is a full example of using XHTML with JavaScript served by PHP as a single-file. <?php if (isset($_SERVER['HTTP_ACCEPT']) && stristr($_SERVER['HTTP_ACCEPT'],'application/xhtml+xml')) { // Client header isset` and explicitly declares XHTML parser support. header('Conte...

HTML5 defines some HTML attributes as boolean; a boolean can only be true or false. The specification simply states that the presence of a boolean attribute implies that the attribute is set to true. In example using a disabled attribute in the following example disables the button input element: &...

Using XHTML you should avoid methods such as document.write and innerHTML as they treat XML as text and do not properly serialize code; an id attribute in HTML is essentially dumped in to the DOM and the id attribute is not serialized which means when trying to reference to it with something such as...

Consider following directory structure to comply with best practices: [ProjectRoot] |---[app] | |---[resources] | routes.php |---[web] | |---[resources] | | |---[css] | | |---[img] | | |---[js] | .htaccess | index.ph...

This example shows a simple global definition of a complexType. The definition is considered global as it is a child of the xs:schema. Globally defined types can be used elsewhere in the schema. This is the most common form for declaring a global xs:complexType, it defines the child elements using ...

In this example we are creating a new xs:complexType (EmployeeType) based on an existing xs:complexType (PersonType). The construction of this is slightly more complicated. Because the base xs:complexType (PersonType) is considered to be complex (more about this below) we add the <xs:complexCon...

This is where things get a little tricky. We are now restricting an existing xs:complexType. Our SolidStateDriveType derives from HardDiskType but removes the spinUpTime attribute and the RotationSpeed element. Notice the approach for dealing with attributes and elements is different. To remove an ...

After installing the SDK, atlas-run-standalone starts a JIRA instance with the latest released version. atlas-run-standalone --product jira The instance is available http://localhost:2990/jira The created instance is for testing only. It provides an other directory structure as production insta...

It is possible to customize the JIRA version, the port or the context path. atlas-run-standalone --product jira --version 6.0 --http-port 1337 --context-path issues The JIRA 6 instance is available under http://localhost:1337/issues There are more parameters that can be set for running atlas-ru...

Failing to load a file The first possible error is failing to load the library. In that case an OSError is usually raised. This is either because the file doesn't exists (or can't be found by the OS): >>> cdll.LoadLibrary("foobar.so") Traceback (most recent call last): File &...

Let's combine all of the examples above into one complex scenario: using libc's lfind function. For more details about the function, read the man page. I urge you to read it before going on. First, we'll define the proper prototypes: >>> compar_proto = CFUNCTYPE(c_int, POINTER(c_int), PO...

The easiest way to run a local JIRA instance, is to install the SDK and run atlas-run-standalone For further details see Starting a local JIRA test instance Please note that this runs a local test instance and is not meant for production.
