Detailed explanation-1: -Queries retrieve rows and columns from tables. After you run a query, you can further limit the number of items shown in the datasheet by applying filters. Filters are a good choice when you want to temporarily limit the query results without going into Design View to edit your query.
Detailed explanation-2: -Equality operators When used in a query, these can be used to select individual records. For example: SELECT FirstName, LastName FROM Customer WHERE CustomerID = 13; Or we can use them to retrieve records that meet a specified criteria.
Detailed explanation-3: -The SELECT command is the primary means of retrieving data from a MySQL database. While the basic command allows you to specify the columns you want to display, the table to pull from, and the output format to use, much of the power of SELECT comes from its ability to filter results.
Detailed explanation-4: -Filters you apply to the query definition are called query filters. You use query filters to reduce the amount of data retrieved from the data source. Query filters decrease the time it takes to run the report and ensure that only the data relevant to the report users is saved with the document.
