+### Description
+
+An identifier is a string used to identify a database object such as a table, view, schema, column, etc. Spark SQL has regular identifiers and delimited identifiers, which are enclosed within backticks. Both regular identifiers and delimited identifiers are case-insensitive.
+
+### Syntax
+
+#### Regular Identifier
+
+{% highlight sql %}
+{ letter | digit | '_' } [ , ... ]
+{% endhighlight %}
+Note: If `spark.sql.ansi.enabled` is set to true, ANSI SQL reserved keywords cannot be used as identifiers. For more details, please refer to [ANSI Compliance](sql-ref-ansi-compliance.html).
+
+#### Delimited Identifier
+
+{% highlight sql %}
+`c [ ... ]`
+{% endhighlight %}
+
+### Parameters
+
+<dl>
+  <dt><code><em>letter</em></code></dt>
+  <dd>
+    Any letter from A-Z or a-z.
+  </dd>
+</dl>
+<dl>
+  <dt><code><em>digit</em></code></dt>
+  <dd>
+    Any numeral from 0 to 9.
+  </dd>
+</dl>
+<dl>
+  <dt><code><em>c</em></code></dt>
+  <dd>
+    Any character from the character set. Use <code>`</code> to escape special characters (e.g., <code>`</code>).
+  </dd>
+</dl>
+
+### Examples
+
+{% highlight sql %}
+-- This CREATE TABLE fails with ParseException because of the illegal identifier name a.b
+CREATE TABLE test (a.b int);
+org.apache.spark.sql.catalyst.parser.ParseException:
+no viable alternative at input 'CREATE TABLE test (a.'(line 1, pos 20)
+
+-- This CREATE TABLE works
+CREATE TABLE test (`a.b` int);
+
+-- This CREATE TABLE fails with ParseException because special character ` is not escaped
+CREATE TABLE test1 (`a`b` int);
+org.apache.spark.sql.catalyst.parser.ParseException:
+no viable alternative at input 'CREATE TABLE test (`a`b`'(line 1, pos 23)
+
+-- This CREATE TABLE works
+CREATE TABLE test (`a``b` int);
+{% endhighlight %}
