No. Most queries list off data, but does not affect the underlying data. Certain types of query can be used to change data in a table, but do not re-arrange the order of the data in the table itself. That is determined by the indexes, mainly the primary key. You can sort the data in the table itself and have it remain that way.
Update queries modify information within a record at one or more fields at a time.Append queries copy complete records at a time, adding to the existing set of records in a table.For example, if an "Address" field needs to be changed for the records in a table, you can use an update query to make that change. If you have two tables with various "Customer Information" listings, you can use an append query to copy the records of one table to the other.
This is called a correlated sub-query.
The query that provides the underlying information for a report is known as the data source query. It is used to retrieve specific data from a database that will be included in the report. The data source query helps ensure that the report is accurately populated with the necessary information.
Criterion
Yes.
The idea here is that the query returns either the number of records which match the query, or the number of records specified in the LIMIT clause - whichever is less. In this case, 30 is less than 2010, so all 30 records will be returned.

To order the records in the answer to a query in a particular way.
Records are the data that's stored in a database and a query is a command used to display and/or manipulate records (for example, adding/deleting records, displaying records by a search term, sorting records).
To display the total number of records in an opened table, you can use the SQL query: SELECT COUNT(*) FROM [table_name]. This query will return the total number of records present in the specified table.
