问题 I am working with a temporary table in Netezza that contains the columns id, gender, start_date, and end_date. I want to add a new column to this table that contains a default date of 2019-01-01 for all rows. The table to which I want to add this column is a local temp table, so ALTER TABLE does not work ("Error: Operation not allowed on a temp table"). To get around this, I created a new temp table as follows: DROP TABLE new_temp_table IF EXISTS; GO SELECT id, gender, start_date, end_date,

问题 I'm trying a simple SQL select into statement on teradata tables, and following the syntax I found here. The statement is the following: select * into DBNAME.account_backup from DBNAME.account; When I run this code I get the following error: SELECT Failed. 3706: Syntax error: INTO clause is not allowed The two tables have precisely the same format (I copied the SQL which created the first table and pasted it to create the second, changing only the name).

Here is what I have attempted: INSERT INTO B`(`ad_id`, `ad_advertiser`, `ad_ln`, `ad_expire`) SELECT * FROM A WHERE YEAR( ad_expire ) <=

问题 I have a one-time operation I need to perform, and am hoping I can do it with a SQL statement (in LINQPad). I need to grab data from two tables, then insert those vals into another one. Specifically, I need to populate the CustomerCategoryLog table with data for each unique combination of Unit/MemberNo/CustNo from the Customers table, adding the corresponding NewBiz value from the MasterUnitsProjSales table. Pseudo-SQL is something like this: // First, need each unique combination of Unit,
