-h4. +arel_table+
-
-The +arel_table+ method is used in the following sections to gain access to more advanced functionality of the Active Relation building language. You may see examples such as this:
-
-<ruby>
-Post.where(Post.arel_table[:comments_count].eq(5)))
-</ruby>
-
-Don't be alarmed! This method returns an +Arel::Table+ object which provides methods for accessing fields and building queries, as you'll see in the following sections.
-
-h4. +eq+
-
-The +eq+ method can be used to check if a field is a specific value:
-
-<ruby>
-Post.where(Post.arel_table[:comments_count].eq(5))
-</ruby>
-
-This method's opposite is +not_eq+.
-
-h4. +eq_any+
-
-Checks if the specified field matches any of the given values.
-
-<ruby>
-Post.where(Post.arel_table[:comments_count].eq_any([1,2])
-</ruby>
-
-This method's opposite is +not_eq_any+.
-
-h4. +in+
-
-To check if a field is within a given group of values, use the +in+ method:
-
-<ruby>
-Post.where(Post.arel_table[:id].in([1,2,3]))
-</ruby>
-
-This method's opposite is +not_in+.
-
-h4. +in_any+
-
-Check if a field is within any one of a group of values:
-
-<ruby>
-Post.where(Post.arel_table[:id]).in_any([1,2,3], [4,5,6])
-</ruby>
-
-This method's opposite is +not_in_any+.
-
-h4. +in_all+
-
-Check if a field is within all of the specified groups of values:
-
-<ruby>
-Post.where(Post.arel_table[:id]).in_all([1,2,3], [1,4,6])
-</ruby>
-
-This method's opposite is +not_in_all+.
-
-h4. +matches+
-
-Match a specific field with a given value. Use +%+ for wildcard searching.
-
-<ruby>
-Post.where(Post.arel_table[:author].matches("Ryan%"))
-</ruby>
-
-This method's opposite is +does_not_match+.
-
-h4. +matches_any+
-
-Match a specific field with any given value. Use +%+ for wildcard searching.
-
-<ruby>
-Post.where(Post.arel_table[:author].matches_any(["Ryan%", "Yehuda%"]))
-</ruby>
-
-This method's opposite is +does_not_match_any+
-
-h4. +matches_all+
-
-Match a specific field with all given values. Use +%+ for wild card searching.
-
-<ruby>
-Post.where(Post.arel_table[:author].matches_all(["Ryan%", "%Bigg"]))
-</ruby>
-
-This method's opposite is +does_not_match_all+.
-
-h4. +gteq+
-
-Check for a field greater than or equal to a specific value.
-
-<ruby>
-Post.where(Post.arel_table[:comments_count].gteq(1))
-</ruby>
-
-This method's opposite is +lteq+.
-
-h4. +gteq_any+
-
-Check for a field greater than or equal to any of the given values.
-
-<ruby>
-Post.where(Post.arel_table[:comments_count].gteq_any([1,2]))
-</ruby>
-
-This method's opposite is +lteq_any+.
-
-h4. +gteq_all+
-
-Check for a field greater than or equal to all of the given values.
-
-<ruby>
-Post.where(Post.arel_table[:comments_count].gteq_all([1,2]))
-</ruby>
-
-This method's opposite is +lteq_all+.
-
-h4. +or+
-
-Allows you to chain queries to get results matching either condition:
-
-<ruby>
-title = Post.arel_table[:title]
-Post.where(title.eq("Active").or(title.eq("Record")))
-</ruby>
-
-Note that this method is called on the end of the +eq+ method here, rather than the +where+.
-
 h3. Ordering
 
 To retrieve records from the database in a specific order, you can use the +order+ method.
