    <p>I am looking for a ruby-specific solution to insert multiple rows using the <a href="https://dev.mysql.com/doc/refman/5.1/en/insert.html" rel="nofollow noreferrer">INSERT..VALUES syntax</a></p> <p>Currently I am generating individual insert statements, but this is very inefficient from a database perspective. I found some related questions, but not exactly what I'm looking for.</p> <p><strong>Example INSERT Statements (currently):</strong></p> <pre><code>INSERT INTO qux SELECT 1,3,'foo'; INSERT INTO qux SELECT 4,11,'bar'; INSERT INTO qux SELECT 12,19,'baz'; </code></pre> <p><a href="https://stackoverflow.com/questions/10022178/insert-multiple-records-using-ruby-on-rails-active-record">INSERT multiple records using ruby on rails active record</a></p> <p>The above question uses ActiveRecord to achieve what I am looking to do, but I am looking for a pure ruby approach.</p> <p><a href="https://stackoverflow.com/questions/9288593/how-do-i-perform-transactions-with-ruby-mysql2">how do I perform transactions with ruby mysql2</a></p> <p>The above question uses transactions to achieve a result similar to my needs. However this is still not as efficient as using one INSERT VALUES statement.</p> <p><strong>Example data:</strong></p> <pre><code>start,end,name 1,3,foo 4,11,bar 12,19,baz </code></pre> <p><strong>INSERT VALUES Statement (desired):</strong></p> <pre><code>INSERT INTO qux VALUES (1,3,'foo'),(4,11,'bar'),(12,19,'baz'); </code></pre> <p>Any gem/codebase that already exists with this functionality?</p> <p>UPDATE: I do not use and do not plan to use ActiveRecord in this particular project. I interact directly with the MySQL database and would love to know of any solution to my problem. One option may be building the functionality myself; however I don't want to re-invent the wheel here.</p>

    3. COI second the ar-extensions suggestion, but if you're determined to avoid ActiveRecord and your data models are simple enough, just roll your own solution by building a giant SQL string to execute and do the inserts.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
