<p>Here is a schema definition and sample data.</p>
<p>Sample schema:</p>
<p>Execution example:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>table_create Tags TABLE_PAT_KEY ShortText
# [[0, 1337566253.89858, 0.000355720520019531], true]
table_create Memos TABLE_HASH_KEY ShortText
# [[0, 1337566253.89858, 0.000355720520019531], true]
column_create Memos tag COLUMN_SCALAR ShortText
# [[0, 1337566253.89858, 0.000355720520019531], true]
column_create Tags memos_tag COLUMN_INDEX Memos tag
# [[0, 1337566253.89858, 0.000355720520019531], true]
</pre></div>
</div>
<p>Sample data:</p>
<p>Execution example:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>load --table Memos
[
{"_key": "Groonga is fast", "tag": "groonga"},
{"_key": "Mroonga is fast", "tag": "mroonga"},

{"_key": "Droonga is fast", "tag": "droonga"},
{"_key": "Groonga is a HTTP server", "tag": "groonga"}
]
# [[0, 1337566253.89858, 0.000355720520019531], 5]
</pre></div>
</div>
<p>Here is the simple usage of <code class="docutils literal notranslate"><span class="pre">in_values</span></code> function which selects the records - the value of <code class="docutils literal notranslate"><span class="pre">tag</span></code> column is “groonga” or “mroonga” or “droonga”.</p>
<p>Execution example:</p>
<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>select Memos --output_columns _key,tag --filter 'in_values(tag, "groonga", "mroonga", "droonga")' --sort_keys _id
# [
# [
# 0,
# 1337566253.89858,
# 0.000355720520019531
# ],
# [
# [
# [
# 4
# ],
# [
# [
# "_key",
# "ShortText"

</pre></div>

<p>When executing the above query, you can get the records except “rroonga” because “rroonga” is not specified as value in <code class="docutils literal notranslate"><span class="pre">in_values</span></code>.</p>
