Insert into from select postgres11/18/2023 ![]() ![]() ![]() It inserts all of the line numbers, account numbers, and ‘fixed’ data into the rprtfrmt table, but not in account number order. (SELECT nextval(‘rprtfrmt_seq’), acctno, 1,1,0,0,0,0,0,1 FROM accounts WHERE (accttype = 0 OR accttype = 2) ORDER BY acctno) INSERT INTO rprtfrmt (lineno, bdgtacct, prntline, addline, totllevl, desconly, prntunderln, balshtentry, rprttype, blnkline) Is an ‘order by’ command not recognized in this situation?ĬREATE TEMP SEQUENCE rprtfrmt_seq INCREMENT BY 50 START WITH 50 It is inserting correctly, but the order isn’t correct. I am attempting to insert several rows into a table using data from another table. 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.I’m using Postgres 9.3 on Windows. 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 INSERT statement allows you to insert a new row into a table. 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 Question: Is there a way to insert the selected columns by name reference or must the dummydatatemp always consist of the same columns (and column ordering) as dummydata INSERT INTO dummydata SELECT dummydata. HINT: You will need to rewrite or cast the expression. If you are looking for the way to select data into variables, check it out the PL/pgSQL SELECT INTO statement. LINE 1: INSERT INTO dummydata SELECT dummydatatemp. 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.
