The table value constructor (TVC) uses the `VALUES` keyword to specify a set of row value expressions to construct into a table. The TVC can be used in the `FROM` clause to build an ad hoc table at query time. ```sql VALUES (row_value_list)[,...n] ``` ##### Arguments - **row_value_list**: Comma-delimited list of column values. Enclose each list in parentheses and separate multiple lists with commas. Each list must have the same number of values and values must be in the same order as columns in the table. Each list must contain a value for each column. ## Usage ```sql SELECT expression[,...n] FROM (VALUES (row_value_list)[,...n]) [AS] table_name(column_name[,...n]) ``` > [!Note] > When using the TVC, the `AS` keyword is optional and implied when naming the > table and providing column names. ## Examples - [Select data from an ad hoc table](#select-data-from-an-ad-hoc-table) ### Select data from an ad hoc table ```sql SELECT * FROM (VALUES ('2023-01-01 12:00:00'::TIMESTAMP, 1.23, 4.56), ('2023-01-01 13:00:00'::TIMESTAMP, 2.46, 8.1), ('2023-01-01 13:00:00'::TIMESTAMP, 4.81, 16.2) ) AS data(time, f1, f2) ``` | time | f1 | f2 | | :------------------- | ---: | ---: | | 2023-01-01T12:00:00Z | 1.23 | 4.56 | | 2023-01-01T13:00:00Z | 2.46 | 8.1 | | 2023-01-01T13:00:00Z | 4.81 | 16.2 |
