    <p>For some models in ORMLite I use <code>Guid</code> as <code>Primary/Foreign Key</code> - it allows to do bulk inserts without the need to do <code>GetLastInsertedId()</code> after each record inserted. I also use <code>ShortId</code> of <code>int</code> type for search purposes or passing in URL parameter (like blog post integer id) that should be autoincremented after each insert.</p> <p>I don't understand how to make <code>[AutoIncrement]</code> work on non-primary key column in PostgreSQL. What I'm doing wrong?</p> <p>Here is an example of my class:</p> <pre><code>[Alias("ProductProperties")] public class ProductProperty : IHasShortId, IHasName { public ProductProperty() { Id = Guid.NewGuid(); } [PrimaryKey] public Guid Id { get; set; } [AutoIncrement] public int ShortId { get; set; } public string Name { get; set; } [ForeignKey(typeof(ProductPropertyType))] public int PropertyTypeId { get; set; } } </code></pre> <p>It generates create table script with <code>short_id</code> as <code>integer</code>, not <code>serial</code>:</p> <pre><code>CREATE TABLE product_properties ( id uuid NOT NULL, short_id integer NOT NULL, name text, property_type_id integer NOT NULL, CONSTRAINT product_properties_pkey PRIMARY KEY (id), CONSTRAINT "FK_product_properties_product_property_types_PropertyTypeId" FOREIGN KEY (property_type_id) REFERENCES product_property_types (short_id) MATCH Unknown ON UPDATE NO ACTION ON DELETE NO ACTION ) WITH ( OIDS=FALSE ); ALTER TABLE product_properties OWNER TO postgres; </code></pre> <p><strong>UPDATE:</strong></p> <p>I was able to fix this by patching ORMLite source code: <a href="https://github.com/ServiceStack/ServiceStack.OrmLite/blob/master/src/ServiceStack.OrmLite/OrmLiteConfigExtensions.cs#L127-L128" rel="nofollow">https://github.com/ServiceStack/ServiceStack.OrmLite/blob/master/src/ServiceStack.OrmLite/OrmLiteConfigExtensions.cs#L127-L128</a></p> <p>Commented the <code>isPrimaryKey &amp;&amp;</code> line.</p> <p>Also edited ServiceStack.OrmLite.OrmLiteDialectProviderBase.cs lines 385-403</p> <p>from</p> <pre><code>if (isPrimaryKey) { sql.Append(" PRIMARY KEY"); if (autoIncrement) { sql.Append(" ").Append(AutoIncrementDefinition); } } else { if (isNullable) { sql.Append(" NULL"); } else { sql.Append(" NOT NULL"); } } </code></pre> <p>to</p> <pre><code> if (autoIncrement) { sql.Append(" ").Append(AutoIncrementDefinition); } if (isPrimaryKey) { sql.Append(" PRIMARY KEY"); } else { if (isNullable) { sql.Append(" NULL"); } else { sql.Append(" NOT NULL"); } } </code></pre> <p>Why does ORMLite restricts AutoIncrement to primary keys only?</p>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
