SELECT what_to_select
FROM which_table
WHERE conditions_to_satisfy;
what_to_select
indicates what you want to see. This can be a list of columns, or *
to indicate “all columns.” which_table
indicates the table from which you want to retrieve data. The WHERE
clause is optional. If it is present, conditions_to_satisfy
specifies one or more conditions that rows must satisfy to qualify for retrieval.
