The SELECT statement is formed by at least two clauses: the SELECT clause and the FROM clause. The clause WHERE is optional. Observe that the SELECT statement, like any other SQL statement, ends in a semicolon. The functions of each these clauses are summarized as follows:
- The SELECT clause lists the columns to display. The attributes listed in this clause are the columns of the resulting relation.
- The FROM clause lists the tables from which to obtain the data. The columns mentioned in the SELECT clause must be columns of the tables listed in the FROM clause.
- The where clause specifies the condition or conditions that need to be satisfied by the rows of the tables indicated in the FROM clause.
As a way to remember the basic structure of the SELECT statement, some authors summarize its functionality by saying that "you SELECT columns FROM tables WHERE the rows satisfy certain condition."
Based on the Colonial Adventure Tours database, create a SELECT statement using all the clauses shown above. In addition to the statement, share with the class what database you created the statement for. Then, compare, contrast, and evaluate your statement with those of your classmates. Are they similar? Are there any syntax differences?
