temp-tables

I'm trying to setup temporary tables for unit-testing purposes. So far I managed to create a temporary table which copies the structure of an existing table: CREATE TEMP TABLE t_mytable (LIKE mytable INCLUDING DEFAULTS); But this lacks the data from the original table. I can copy the data into the temporary table by using a CREATE TABLE AS statement instead: CREATE TEMP TABLE t_mytable AS SELECT * FROM mytable; But then the structure of t_mytable will not be identical, e.g. column sizes and default values are different. Is there a single statement which copies everything? Another problem with

We have a school district with 38 elementary schools. The kids took a test. The averages for the schools are widely dispersed, but I want to compare the averages of JUST THE TOP 10 students from each school. Requirement: use temporary tables only. I have done this in a very work-intensive, error-prone sort of way as follows. (sch_code = e.g., 9043; -- schabbrev = e.g., "Carter"; -- totpct_stu = e.g., 61.3) DROP TEMPORARY TABLE IF EXISTS avg_top10 ; CREATE TEMPORARY TABLE avg_top10 ( sch_code VARCHAR(4), schabbrev VARCHAR(75), totpct_stu DECIMAL(5,1) ); INSERT INTO avg_top10 SELECT sch_code ,

This could be because i'm tired, or that I'm new to postgres. However, I'm trying to use a temp table in a function and postgres is complaining that the "relation does not exist". Yet, if I take the body of my function, and execute it it works just fine. Below is a sample of the type of function I'm trying to create. Keeping in mind I've stripped out everything interesting such that it's close to a bare minimum to show my problem. CREATE OR REPLACE FUNCTION dbo.somefunc() RETURNS void AS $BODY$ CREATE TEMPORARY TABLE work_list ( name text, level smallint ); insert into work_list (name, level)

I am creating a temp table with a query like this: CREATE TEMPORARY TABLE temp_table SELECT * FROM regular_table WHERE 1 But regular_table has FULLTEXT index on some of the fields. I try to do a FULLTEXT search on the new temporary table and I get an error telling me "Can't find FULLTEXT index matching the column list ". So obviusly the index is not copying over to the new table. Is there a way to force this? Thanks. You could use CREATE TEMPORARY TABLE temp_table LIKE regular_table , but that will create all the indexes, so when you do INSERT INTO temp_table SELECT * FROM regular_table , the

am creating a GLOBAL TEMPORARY TABLE in DB2. and when i surfed i got a two way to create 1. Declare 2. Create. 1. DECLARE GLOBAL TEMPORARY TABLE SESSION.TEMP_EMP (EMPNO CHAR(6) NOT NULL, SALARY DECIMAL(9, 2), BONUS DECIMAL(9, 2), COMM DECIMAL(9, 2)) WITH REPLACE ON COMMIT PRESERVE ROWS ; 2. CREATE GLOBAL TEMPORARY TABLE TMPDEPT (TMPDEPTNO CHAR(3) NOT NULL, TMPDEPTNAME VARCHAR(36) NOT NULL, TMPMGRNO CHAR(6), TMPLOCATION CHAR(16) ) ON COMMIT PRESERVE ROWS ; and from IBM site i got a info that create is the best since its being persistent , allowing all user sessions to access the same table
