<div><p>It specifies values loaded to records.
Values should satisfy <tt class="docutils literal"><span class="pre">input_type</span></tt> format.
If you specify "json" as <tt class="docutils literal"><span class="pre">input_type</span></tt>, you can choose a format from below:</p>
<dl class="docutils">
<dt><tt class="docutils literal"><span class="pre">Format</span> <span class="pre">1:</span></tt></dt>
<dd>[[COLUMN_NAME1, COLUMN_NAME2,..], [VALUE1, VALUE2,..], [VALUE1, VALUE2,..],..]</dd>
<dt><tt class="docutils literal"><span class="pre">Format</span> <span class="pre">2:</span></tt></dt>

<p>When a target table contains primary key, you must specify <tt class="docutils literal"><span class="pre">_key</span></tt> column (pseudo column associated primary key) as the one of <tt class="docutils literal"><span class="pre">COLUMN_NAME</span></tt>.</p>
<p>If <tt class="docutils literal"><span class="pre">values</span></tt> isn't specified any values, they are read from the standard input until all opened parenthes match their closed ones.
You don't have to enclose them with single-quotes or double-quotes, but if you specified values with <tt class="docutils literal"><span class="pre">values</span></tt> parameter, you should do.</p>
<p>In following values, you also don't have to enclose any spaces (' ') with single-quotes or double-quotes.</p>

If <tt class="docutils literal"><span class="pre">ifexists</span></tt> specifies <tt class="docutils literal"><span class="pre">grn_expr</span></tt> string (default: true) and
its value is true, values in other (all columns excluding <tt class="docutils literal"><span class="pre">_key</span></tt>
