<h1 class="topictitle1">Use the LABEL ON statement</h1>
<div><div class="section">Normally, the column name is used as the column heading when showing
the output of a SELECT statement in interactive SQL. By using the LABEL ON
statement, you can create a more descriptive label for the column name. Because
you run your examples in interactive SQL, you use the LABEL ON statement to
change the column headings. Even though the column names were descriptive,
it is easier to read if the column headings show each part of the name on
a single line. It also allows you to see more columns of data on a single
display.<p>To change the labels for your columns, follow these steps:</p>
</div>
<ol><li class="stepexpand"><span>Enter <kbd class="userinput">LABEL ON COLUMN</kbd> on the Enter SQL Statements
display.</span></li>
<li class="stepexpand"><span>Press F4 (Prompt). The following display appears:</span> <div class="p"><pre class="screen"> Specify LABEL ON Statement
