Query syntax

SELECT select_expr [, select_expr ] ... FROM table_references [, table_references ] ... [ WHERE where_condition ]

The most commonly used clauses of SELECT statements are these:

• Each select_expr indicates a column that you want to retrieve. There must be at least one select_expr.
• A select list consisting only of a single unqualified * can be used as shorthand to select all columns from tables, but all tables must have the same columns and column order
• table_references indicates the table or tables from which to retrieve rows
• The WHERE clause, if given, indicates the condition or conditions that rows must satisfy to be selected. where_condition is an expression that evaluates to true for each row to be selected. The statement selects all rows if there is no WHERE clause.
