<h2>Return Type</h2>
<p><strong>Boolean (true/false)</strong></p>

<h2>Examples</h2>
<h3>Example 1</h3>
<p>Let's suppose in our examples `TextField` is a custom field text already configured for the current Jira server instance and `TestDB` represents the database resource name configured in the server context. For more details see <ac:link><ri:page ri:content-title="SQL data sources" /></ac:link>.</p>
<ac:structured-macro ac:name="code" ac:schema-version="1">
<ac:plain-text-body>
<![CDATATextField=databaseAvailable("TestDB"); //will set 'TextField' value to 'true']>
</ac:plain-text-body>
</ac:structured-macro>

<h3>Example 2</h3>

<ac:structured-macro ac:name="code" ac:schema-version="1">
<ac:plain-text-body>
<![CDATATextField=databaseAvailable("TestDB", "select pname from project"); //will set 'TextField' value to 'true' if the SQL passed in can be executed]>
</ac:plain-text-body>
</ac:structured-macro>

<h3>Example 3</h3>

<ac:structured-macro ac:name="code" ac:schema-version="1">
<ac:plain-text-body>
<![CDATATextField=databaseAvailable("TestDB", "select pname from inexistentTableName");//will set 'TextField' value to 'false', because the SQL passed in cannot be executed]>
</ac:plain-text-body>
</ac:structured-macro>

<h3>Example 4</h3>

<ac:structured-macro ac:name="code" ac:schema-version="1">
<ac:plain-text-body>
<![CDATATextField=databaseAvailable("InexistentTestDB", "select pname from project");//will set 'TextField' value to 'false', because the database resource does not exist]>
</ac:plain-text-body>
