+
+<h2 id="handling-hbase-data">Handling HBase Data</h2>
+
+<p>To query HBase data in Drill, convert every column of an HBase table to/from byte arrays from/to an SQL data type using CONVERT_TO or CONVERT_FROM. For examples of how to use these functions, see &quot;Convert and Cast Functions&quot;.</p>
+
+<h2 id="handling-textual-data">Handling Textual Data</h2>
+
+<p>In a textual file, such as CSV, Drill interprets every field as a VARCHAR, as previously mentioned. In addition to using the CAST function, you can also use to_char, to_date, to_number, and to_timestamp. If the SELECT statement includes a WHERE clause that compares a column of an unknown data type, cast both the value of the column and the comparison value in the WHERE clause.</p>
+
+<h2 id="handling-json-and-parquet-data">Handling JSON and Parquet Data</h2>
+
+<p>Complex and nested data structures in JSON and Parquet files are of map and array types.</p>
+
+<p>A map is a set of name/value pairs. A value in a map can be a scalar type, such as string or int, or a complex type, such as an array or another map.
+An array is a repeated list of values. A value in an array can be a scalar type, such as string or int, or an array can be a complex type, such as a map or another array.</p>
+
+<p>Drill reads/writes maps and arrays from/to JSON and Parquet files. In Drill, you do not cast a map or array to another type.</p>
+
+<p>The following example shows a JSON map having scalar values:</p>
+<div class="highlight"><pre><code class="language-text" data-lang="text">phoneNumber: 
+{ 
+  areaCode: 622, 
+  number: 1567845
+}
+</code></pre></div>
+<p>The following example shows a JSON map having an array as a value:</p>
+<div class="highlight"><pre><code class="language-text" data-lang="text">{ citiesLived : 
+  [ 
+    { place : Los Angeles,       
+      yearsLived : [ 1989, 1993, 1998, 2002]     
+    } 
+  ] 
+}
+</code></pre></div>
+<p>The following example shows a JSON array having scalar values:</p>
+<div class="highlight"><pre><code class="language-text" data-lang="text">yearsLived: [1990, 1993, 1998, 2008]
+</code></pre></div>
+<p>The following example shows a JSON array having complex type values:</p>
+<div class="highlight"><pre><code class="language-text" data-lang="text">children: 
+  [ 
+    { age : 10,
+      gender : Male,
+      name : Earl
+    },
+    { age : 6,
+      gender : Male,
+      name : Sam,
+    { age : 8,
+      gender : Male,
+      name : Kit
+    }
+  ]
+</code></pre></div>
+<h2 id="all-text-mode-option">All text mode option</h2>
+
+<p>All text mode is a system option for controlling how Drill implicitly casts JSON data. When reading numerical values from a JSON file, Drill implicitly casts a number to the DOUBLE or BIGINT type depending on the presence or absence a decimal point. If some numbers in a JSON map or array appear with and without a decimal point, such as 0 and 0.0, Drill throws a schema change error. To prevent Drill from attempting to read such data, <a href="/docs/json-data-model#handling-type-differences">set all_text_mode</a> to true. In all text mode, Drill implicitly casts JSON data to VARCHAR, which you can subsequently cast to desired types.</p>
+
+<p>Drill reads numbers without decimal point as BIGINT values by default. The range of BIGINT is -9223372036854775808 to 9223372036854775807. A BIGINT result outside this range produces an error. Use <code>all_text_mode</code> to select data as VARCHAR and then cast the data to a numerical type.</p>
+
+<h2 id="guidelines-for-using-float-and-double">Guidelines for Using Float and Double</h2>
+
+<p>FLOAT and DOUBLE yield approximate results. These are variable-precision numeric types. Drill does not cast/convert all values precisely to the internal format, but instead stores approximations. Slight differences can occur in the value stored and retrieved. The following guidelines are recommended:</p>
+
+<ul>
+<li>For conversions involving monetary calculations, for example, that require precise results use the decimal type instead of float or double.</li>
+<li>For complex calculations or mission-critical applications, especially those involving infinity and underflow situations, carefully consider the limitations of type casting that involves FLOAT or DOUBLE.</li>
+<li>Equality comparisons between floating-point values can produce unexpected results.</li>
+</ul>
+
+<p>Values of FLOAT and DOUBLE that are less than the lowest value in the range (more negative) cause an error. Rounding can occur if the precision of an input number is too high. </p>

+<h2 id="with-clause">WITH Clause</h2>
+
+<p>The WITH clause is an optional clause used to contain one or more common table
+expressions (CTE) where each CTE defines a temporary table that exists for the
+duration of the query. Each subquery in the WITH clause specifies a table
+name, an optional list of column names, and a SELECT statement.</p>
+
+<h2 id="syntax">Syntax</h2>
+
+<p>The WITH clause supports the following syntax:</p>
+<div class="highlight"><pre><code class="language-text" data-lang="text">[ WITH with_subquery [, ...] ]
+where with_subquery is:
+with_subquery_table_name [ ( column_name [, ...] ) ] AS ( query ) 
+</code></pre></div>
+<h2 id="parameters">Parameters</h2>
+
+<p><em>with_subquery</em>table_name_</p>
+
+<p>A unique name for a temporary table that defines the results of a WITH clause
+subquery. You cannot use duplicate names within a single WITH clause. You must
+give each subquery a table name that can be referenced in the FROM clause.</p>
+
+<p><em>column</em>name_</p>
+
+<p>An optional list of output column names for the WITH clause subquery,
+separated by commas. The number of column names specified must be equal to or
+less than the number of columns defined by the subquery.</p>
+
+<p><em>query</em></p>
+
+<p>Any SELECT query that Drill supports. See
+<a href="/docs/SELECT+Statements">SELECT</a>.</p>
+
+<h2 id="usage-notes">Usage Notes</h2>
+
+<p>Use the WITH clause to efficiently define temporary tables that Drill can
+access throughout the execution of a single query. The WITH clause is
+typically a simpler alternative to using subqueries in the main body of the
+SELECT statement. In some cases, Drill can evaluate a WITH subquery once and
+reuse the results for query optimization.</p>
+
+<p>You can use a WITH clause in the following SQL statements:</p>
+
+<ul>
+<li><p>SELECT (including subqueries within SELECT statements)</p></li>
+<li><p>CREATE TABLE AS</p></li>
+<li><p>CREATE VIEW</p></li>
+<li><p>EXPLAIN</p></li>
+</ul>
+
+<p>You can reference the temporary tables in the FROM clause of the query. If the
+FROM clause does not reference any tables defined by the WITH clause, Drill
+ignores the WITH clause and executes the query as normal.</p>
+
+<p>Drill can only reference a table defined by a WITH clause subquery in the
+scope of the SELECT query that the WITH clause begins. For example, you can
+reference such a table in the FROM clause of a subquery in the SELECT list,
+WHERE clause, or HAVING clause. You cannot use a WITH clause in a subquery and
+reference its table in the FROM clause of the main query or another subquery.</p>
+
+<p>You cannot specify another WITH clause inside a WITH clause subquery.</p>
+
+<p>For example, the following query includes a forward reference to table t2 in
+the definition of table t1:</p>
+
+<h2 id="example">Example</h2>
+
+<p>The following example shows the WITH clause used to create a WITH query named
+<code>emp_data</code> that selects all of the rows from the <code>employee.json</code> file. The
+main query selects the <code>full_name, position_title, salary</code>, and <code>hire_date</code>
+rows from the <code>emp_data</code> temporary table (created from the WITH subquery) and
+orders the results by the hire date. The <code>emp_data</code> table only exists for the
+duration of the query.</p>
+
+<p><strong>Note:</strong> The <code>employee.json</code> file is included with the Drill installation. It is located in the <code>cp.default</code> workspace which is configured by default. </p>

+<h1>SHOW DATABASES AND SHOW SCHEMAS Command</h1>
+
+</div>
+
+<div class="int_text" align="left"><p>The SHOW DATABASES and SHOW SCHEMAS commands generate a list of available Drill schemas that you can query.</p>
+
+<h2 id="syntax">Syntax</h2>
+
+<p>The SHOW DATABASES and SHOW SCHEMAS commands support the following syntax:</p>
+<div class="highlight"><pre><code class="language-text" data-lang="text">SHOW DATABASES;
+SHOW SCHEMAS;
+</code></pre></div>
+<p><strong>Note:</strong> These commands generate the same results.</p>
+
+<h2 id="usage-notes">Usage Notes</h2>
+
+<p>You may want to run the SHOW DATABASES or SHOW SCHEMAS command to see a list of the configured storage plugins and workspaces in Drill before you issue the USE command to switch to a particular schema for your queries.</p>
+
+<p>In Drill, a database or schema is a configured storage plugin instance or a configured storage plugin instance with a configured workspace. For example, dfs.donuts where dfs is the file system configured as a storage plugin instance, and donuts is a configured workspace.</p>
+
+<p>You can configure and use multiple storage plugins and workspaces in Drill.  See <a href="/docs/storage-plugin-registration">Storage Plugin Registration</a> and <a href="/docs/workspaces">Workspaces</a>.</p>
+
+<h2 id="example">Example</h2>
+
+<p>The following example uses the SHOW DATABASES and SHOW SCHEMAS commands to generate a list of the available schemas in Drill. Some of the results that display are specific to all Drill installations, such as <code>cp.default</code> and <code>dfs.default</code>, while others vary based on your specific storage plugin and workspace configurations.</p>

+<h1>SHOW TABLES Command</h1>
+
+</div>
+
+<div class="int_text" align="left"><p>The SHOW TABLES command returns a list of views created within a schema. It
+also returns the tables that exist in Hive, HBase, and MapR-DB when you have
+these data sources configured as storage plugin instances. See<a href="/docs/storage-plugin-registration"> Storage Plugin
+Registration</a>.</p>
+
+<h2 id="syntax">Syntax</h2>
+
+<p>The SHOW TABLES command supports the following syntax:</p>
+<div class="highlight"><pre><code class="language-text" data-lang="text">SHOW TABLES;
+</code></pre></div>
+<h2 id="usage-notes">Usage Notes</h2>
+
+<p>First issue the USE command to identify the schema for which you want to view
+tables or views. For example, the following USE statement tells Drill that you
+only want information from the <code>dfs.myviews</code> schema:</p>
+<div class="highlight"><pre><code class="language-text" data-lang="text">USE dfs.myviews;
+</code></pre></div>
+<p>In this example, “<code>myviews</code>” is a workspace created withing an instance of the
+<code>dfs</code> storage plugin.</p>
+
+<p>When you use a particular schema and then issue the SHOW TABLES command, Drill
+returns the tables and views within that schema.</p>
+
+<h4 id="limitations">Limitations</h4>
+
+<ul>
+<li><p>You can create and query tables within the file system, however Drill does not return these tables when you issue the SHOW TABLES command. You can issue the <a href="/docs/show-files-command">SHOW FILES </a>command to see a list of all files, tables, and views, including those created in Drill. </p></li>
+<li><p>You cannot create Hive, HBase, or MapR-DB tables in Drill. </p></li>
+</ul>
+
+<h2 id="examples">Examples</h2>
+
+<p>The following examples demonstrate the steps that you can follow when you want
+to issue the SHOW TABLES command on the file system, Hive, and HBase.  </p>
+
+<p>Complete the following steps to see views that exist in a file system and
+tables that exist in Hive and HBase data sources:</p>
+
+<ol>
+<li><p>Issue the SHOW SCHEMAS command to see a list of available schemas.</p>
