    <p>I was just trying to do a simple data service connecting to HR schema on Oracle XE DB. I just wrote a simple query with operation which takes an input parameter and gets the result accordingly as per the bind data passed.</p> <p>My Query looks as below</p> <pre><code>SELECT first_name,last_name,email,phone_number,hire_date,salary FROM employees WHERE first_name like :Bind_name </code></pre> <p>I have added a input variable Bind_name and passing it when im requesting the service.</p> <p>But, when i trigger the service i see below error and couldn't find relevant help on web.</p> <pre><code>[2012-06-13 12:42:08,101] ERROR

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
