When it's used in other contexts, it might be necessary to specify the correct data type. When VALUES is used in INSERT, the values are all automatically coerced to the data type of the corresponding destination column. in PostgreSQL, but these names might be different in other database systems.) Example of what i try to accomplish: current database: MyTable character number 'a' '0' 'b' '1' 'c' '1'. Use the INSERT INTO command in conjunction with a SELECT statement to insert. In SQL, we use the SQL INSERT INTO statement to insert records. Use the INSERT INTO command with a grouped set of data to insert new values. We can insert data directly using client tools such as SSMS, Azure Data Studio or directly from an application. (The default column names for VALUES are column1, column2, etc. I'm trying to insert data into a table using SELECT and passing values. The INSERT INTO SELECT statement We want to insert records as regular database activity. It is not required that the AS clause specify names for all the columns, but it's good practice to do so. Note that an AS clause is required when VALUES is used in a FROM clause, just as is true for SELECT. WHERE pno = v.depno AND employees.sales >= v.target
POSTGRESQL INSERT INTO SELECT AND VALUES UPDATE
UPDATE employees SET salary = salary * v.increaseįROM (VALUES(1, 200000, 1.2), (2, 400000, 1.4)) AS v (depno, target, increase) WHERE f.studio = t.studio AND f.kind = t.kind VALUES can also be used where a sub- SELECT might be written, for example in a FROM clause:įROM films f, (VALUES('MGM', 'Horror'), ('UA', 'Sci-Fi')) AS t (studio, kind) ('UA502', 'Bananas', 105, DEFAULT, 'Comedy', '82 minutes'), 7 Answers Sorted by: 246 Multi-value insert syntax is: insert into table values (1,1), (1,2), (1,3), (2,1) But krokodilko's answer is much slicker. In the context of INSERT, entries of a VALUES list can be DEFAULT to indicate that the column default should be used here instead of specifying a value: VALUES ('T_601', 'Yojimbo', 106, '', 'Drama') One can insert one or more rows specified by value expressions, or zero or more rows resulting from a query. INSERT INTO films (code, title, did, date_prod, kind) More usually, VALUES is used within a larger SQL command. This will return a table of two columns and three rows.
