| <h3 id="description">Description</h3> |
| |
| <p><code class="highlighter-rouge">SHOW TABLE EXTENDED</code> will show information for all tables matching the given regular expression. |
| Output includes basic table information and file system information like <code class="highlighter-rouge">Last Access</code>, |
| <code class="highlighter-rouge">Created By</code>, <code class="highlighter-rouge">Type</code>, <code class="highlighter-rouge">Provider</code>, <code class="highlighter-rouge">Table Properties</code>, <code class="highlighter-rouge">Location</code>, <code class="highlighter-rouge">Serde Library</code>, <code class="highlighter-rouge">InputFormat</code>, |
| <code class="highlighter-rouge">OutputFormat</code>, <code class="highlighter-rouge">Storage Properties</code>, <code class="highlighter-rouge">Partition Provider</code>, <code class="highlighter-rouge">Partition Columns</code> and <code class="highlighter-rouge">Schema</code>.</p> |
| |
| <p>If a partition specification is present, it outputs the given partition’s file-system-specific |
| information such as <code class="highlighter-rouge">Partition Parameters</code> and <code class="highlighter-rouge">Partition Statistics</code>. Note that a table regex |
| cannot be used with a partition specification.</p> |

| <h3 id="parameters">Parameters</h3> |
| <dl> |
| <dt><code><em>IN|FROM database_name</em></code></dt> |
| <dd> |
| Specifies database name. If not provided, will use the current database. |
| </dd> |
| <dt><code><em>LIKE string_pattern</em></code></dt> |
| <dd> |
| Specifies the regular expression pattern that is used to filter out unwanted tables. |
| <ul> |
| <li> Except for `*` and `|` character, the pattern works like a regex.</li> |
| <li> `*` alone matches 0 or more characters and `|` is used to separate multiple different regexes, |
| any of which can match. </li> |
| <li> The leading and trailing blanks are trimmed in the input pattern before processing.</li> |
| </ul> |
| </dd> |
| <dt><code><em>partition_spec</em></code></dt> |
| <dd> |
| An optional parameter that specifies a comma separated list of key and value pairs |
| for partitions. Note that a table regex cannot be used with a partition specification.<br /><br /> |
| <b>Syntax:</b> |
| <code> |
| PARTITION ( partition_col_name [ = partition_col_val ] [ , ... ] ) |
