    <p>Joining strings is called "concatenation." The concatenation operator in SQLite is "||". This is an example of concatenating multiple columns into a single column.</p> <pre><code>select Given || " " || Surname as "Full Name" from NameTable; </code></pre> <p>If you want to preserve a unique identifier for each row, you can also select the (implicit) "ROWID" column. One could also select the individual name columns, the aggregate column, and the "ROWID" column to have the full dataset.</p> <pre><code>select ROWID, Given, Surname, Given || " " || Surname as "Full Name" from NameTable; </code></pre> <p>The question on searching is a bit more involved, as it's not clear to me what you are trying to accomplish. Also, in the case where the user is inputting search criteria, the input could be provided in many different ways, e.g. partial or complete Given name or Surname, partial or complete Given name and surname, orders reversed on given and surname, etc. (complicating search).</p> <p>So, depending upon how you are allowing input you could search in different ways. The simplest way would be with a "like" operator. Depending on the size of your dataset, you might be able to create a virtual table that concatenates the Given and Surname columns into a single column and use that column for the like comparison. Or, you could use an "OR" operator to allow matches to either the Given or Surname columns.</p> <p>You may also want to be aware that SQLite supports a full text search engine. <a href="http://www.sqlite.org/fts3.html" rel="nofollow">http://www.sqlite.org/fts3.html</a></p>

    1. COHere's what I'm trying to do: the index was created thus: "CREATE INDEX idxSurnGiv ON NameTable (Surname, Given);" My user enters "Smith, John". I want to find "Smith, John", then I want to back up by one row (alphabetically), and I want to find the previous person, for example "Smith, James". Physically, "James" and "John" could be miles apart in the table, for example James could be at row 12, and John at row 45,676. I need to step back, one name at a time, and retrieve each name that comes just before "Smith, John". This is basically scrolling backward through a list of names.

    2. COWhat you are trying to accomplish (sorting) is usually done with an "Order By" clause (not with an index). For example: select ROWID, Given, Surname, Given || " " || Surname as "Full Name" from NameTable order by 4 asc;

    3. COSo what you & Donal are saying is that I have to build a temporary index, which is a duplicate of an already-existing SQLite index, and manage traversing this temporary index with my own code. Sigh... even xBase/Foxpro (vastly inferior technology) had this feature built-in. OK, thank you both for your time & suggestions.

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.
