A quick way to find data in a database is to use

Spreadsheets excel at crunching numbers. Add a column of figures—your sales or expenses, perhaps—and a quick formula Show
=SUM(A1:A10) can add them up or =AVERAGE(A1:A10) returns the average price. They’re flexible yet powerful.Automatically find and match related data across apps Learn how Databases are better at connecting enormous amounts of data across different tables. You could have a list of your product details in one table, a list of your orders in another, and have each order linked to the products people purchased. Then, instead of typing the price in each time, you’d link the product name in the order table to the product details table and let the database pull in the data on its own. That interconnectivity makes databases more confusing—but also more powerful if you have time to tame the beast. What if you could get the best of both worlds, a way to look up data when you need it in the simplicity of a spreadsheet—or even something easier? That’s what Excel's The Database Way: Linked Records Every time you go through checkout at a store, the point of sales software is looking up everything you purchase in a database. The clerk scans the barcode on an item, turns that into a number, looks up that number in the database, and adds its name and price to your receipt. No one needs to enter the same data multiple times—the database takes care of that. In developer-focused database management systems like MySQL, you’ll do that with JOIN commands that link records across tables. Visual database apps like Airtable and Microsoft Access make things a bit easier.In Airtable, say, you’ll add a Link to Another Record field to your table. Then, to link records, select that field and type in the name of an item from the other table—and Airtable will show a preview of that record’s details. That’s an easy way to pull in one data item from another table. Need to tag authors in your editorial calendar database from your author table or select hotels from a database for a trip plan? Airtable’s Link fields are perfect for that. What we’re discussing here are one-to-one table relationships, the simplest type of database relationships. With MySQL and other advanced database management systems, you can also build one-to-many and many-to-many relationships—great for building advanced database apps, but more than you need to look up individual data items. The Spreadsheet Way: LOOKUP FunctionsSpreadsheets aren’t as interconnected as databases. They’re designed to list data in one place and calculate All you need are
The Let’s try it out. Say you have a product table like the one pictured above, with columns for item name, price, quantity, and description. Underneath are rows including each of your items and their details, in the order you added those products to your store. Want to find an item’s price? A

What is used to search for data stored in a database?Queries. Queries can perform many different functions in a database. Their most common function is to retrieve specific data from the tables. The data you want to see is usually spread across several tables, and queries allow you to view it in a single datasheet.
Which of the following is the fastest possible way to find the data in a table?Fetch by rowid is the fastest query method for a table. The "table fetch by rowid" Oracle metric occurs when rows are fetched using a ROWID (usually recovered from an index), each row returned increments this counter.
What is a query in a database?A query can either be a request for data results from your database or for action on the data, or for both. A query can give you an answer to a simple question, perform calculations, combine data from different tables, add, change, or delete data from a database.
How can I get specific data from database?SELECT statements
