![]() LOG ERRORS INTO errlog ('Cannot Perform Insert') REJECT LIMIT 100 ALTER TABLE EMPS ADD CONSTRAINT PK_EMP_ID PRIMARY KEY(employee_id) ĮXECUTE DBMS_ERRLOG.CREATE_ERROR_LOG('EMPS', 'ERRLOG') Log errors with the Oracle error_logging_clause. (SELECT EMPLOYEE_ID, FIRST_NAME, SALARY, DEPARTMENT_ID FROM EMPS) This example produces the same result as the preceding example but uses a subquery in the DML_table_expression_clause. SELECT EMPLOYEE_ID, FIRST_NAME, SALARY, DEPARTMENT_ID INSERT INTO EMPS (EMPLOYEE_ID, FIRST_NAME, SALARY, DEPARTMENT_ID) SELECT EMPLOYEE_ID, The column ordering and data types must match between the target and the source tables. In this tutorial, you have learned how to use the PostgreSQL SELECT INTO statement to create a new table from the result set of a query.You can insert multiple records into a table from another table using the INSERT FROM SELECT statement, which is a derivative of the basic INSERT statement. The following shows the data from the short_film table: SELECT * FROM short_film Code language: SQL (Structured Query Language) ( sql ) Title Code language: SQL (Structured Query Language) ( sql ) The following statement creates a temporary table named short_film that contains the films whose lengths are under 60 minutes. To verify the table creation, you can query data from the film_r table: SELECT * FROM film_r Code language: SQL (Structured Query Language) ( sql ) Rating = 'R' AND rental_duration = 5 ORDER BY The following statement creates a new table called film_r that contains films with the rating R and rental duration 5 days from the film table. We will use the film table from the sample database for the demonstration. In this case, you can use the CREATE TABLE AS statement which provides more functionality than the SELECT INTO statement. ![]() ![]() Note that you cannot use the SELECT INTO statement in PL/pgSQL because it interprets the INTO clause differently. Besides the WHERE clause, you can use other clauses in the SELECT statement for the SELECT INTO statement such as INNER JOIN, LEFT JOIN, GROUP BY, and HAVING. The WHERE clause allows you to specify the rows from the original tables that should be inserted into the new table. The UNLOGGED keyword if available will make the new table as an unlogged table. The TEMP or TEMPORARY keyword is optional it allows you to create a temporary table instead. To create a new table with the structure and data derived from a result set, you specify the new table name after the INTO keyword. INTO new_table_nameĬode language: SQL (Structured Query Language) ( sql ) The following illustrates the syntax of the PostgreSQL SELECT INTO statement: SELECT Unlike a regular SELECT statement, the SELECT INTO statement does not return a result to the client. The new table will have columns with the names the same as columns of the result set of the query. The PostgreSQL SELECT INTO statement creates a new table and inserts data returned from a query into the table. Introduction to PostgreSQL SELECT INTO statement If you are looking for the way to select data into variables, check it out the PL/pgSQL SELECT INTO statement. ![]() Summary: in this tutorial, you will learn how to use the PostgreSQL SELECT INTO statement to create a new table from the result set of a query.
