SQL Commands. Modify the following select statement to remove the hard-coded values $1.00 and $2.00 from the code and place them in a table of constants. The table sec0306_price_constants is already set up for you. The min_price field = 1.00 and the max_price field = 2.00. When I make a change like this, in addition to replacing the hard-coded values, I often put those values in the select clause so I can see exactly what the values are whenever I run the SQL code. select description from l_foods where price between 1.00 and 2.00 order by description;
SQL
SQL stands for Structured Query Language, is a form of communication that uses queries structured in a specific format to store, manage & retrieve data from a relational database.
Queries
A query is a type of computer programming language that is used to retrieve data from a database. Databases are useful in a variety of ways. They enable the retrieval of records or parts of records, as well as the performance of various calculations prior to displaying the results. A search query is one type of query that many people perform several times per day. A search query is executed every time you use a search engine to find something. When you press the Enter key, the keywords are sent to the search engine, where they are processed by an algorithm that retrieves related results from the search index. Your query's results are displayed on a search engine results page, or SER.
