COUNT

To find the number of items in your library using the SQL Count function, you can use the following query:

SELECT COUNT(*) AS total_items FROM library;

In this query, library is the table's name containing your items. The COUNT(*) function is used to count the number of rows in the table, and the result will be returned as total_items. When you execute this query, it will return the total number of items in your library.

You can use this query in our Handy Library Manager for Windows.

To display totals by item type in a library database using the type field and SQL count, you can use the following SQL query:

SELECT type, COUNT(*) as total FROM library_table GROUP BY type;

In this query, library_table is the name of the table in the library database, and type is the field that represents the item type. The COUNT(*) function is used to count the number of items for each type, and the GROUP BY clause is used to group the results by the item type.

When you run this query, you will get a result that displays the item types and the total count for each type, allowing you to see how many items of each type are available in the library.
