I am writing a code that takes four records through loop then copy them to temporary table calculate average over there of the four records then store that avg value in a variable. My curiosity is just that if its possible for that to work from Data Source window, I think it is also possible for it to work using the hard coding. You can then configure the columns via sub routines if necessary. Yours is starting if you are a worm in the apple , and my workday is ending in a couple of hours. I think so, that's a tool for you to create,delete,modify dbs as well as tables there.
Not only did it not occur to me, but the syntax used to do this is very strange to me although now that I have stared at it for a long time, it's starting to make more sense. I don't want to use that drag and drop thing. The resultset returned by the dataadapter is based on a scheme which does not exist in the DataBase. Thank you once again Waheed, happy to help. I am also curious, how come on my reply to Paul's answer, it shows MigrationUser 1 with 1,510points.
The problem was that the code that I pasted in my earlier post, was doing that in total records of 12 it just picks first 4 records take average of the first 4 selected records and replicate the zip code, age with the record on whose values zip code, age computation was done. Dennis, Did you get the desired results from the query I posted previously? Ben, have you thought of creating a forum for your site and off-loading question based comments on articles into that? This effectively synchronizes the two tables based on the query performed, updating and inserting records as necessary for the two to match. How would I rewrite this query for oracle? But I still received the same error. What i want to do is that there is table which has age and zip code. Except the last one, of course. How odd that I would stumble across this.
Only the rows in the A table: a1,1 , a3,3 have the corresponding rows in the B table b1,1 , b2,3 are included in the result set. For updating the database you use the tables straight. I was biggest fan of ColdFusion and can not stop thinking about it. Thank you for proving such an informative portal and a platform for viewing and sharing different programing problems. The boy table lists boys, the girl table lists girls, and the relationship table lists out romantic relationships between the two what can I say, I am a romantic fool at heart. Take a look what Paul wrote in the first answer. When i ran the whole statement i was very surprised that it affected 28080 rows.
The most easiest and common way is to use join clause in the update statement and use multiple tables in the update statement. I am trying to do the same thing you have done with this join and update, just a little different. I am assuming that you want to find the average age of people in a zip code; is this correct? Hi Paul, thank you for your reply. To query data from these tables, you need to use two inner join clauses in the statement as follows:. I now need to replicate this query in Oracle. But in general, I do like that the blog posts can lead to more indepth conversations. It is certainly very useful though! Yet, on occasion, it may prove beneficial to alter the contents of a table indirectly, by using a subset of data obtained from secondary query statement.
The A table links to the B table using a foreign key column named f. Here is an interesting blog post from Hugo Kurnelis, talking about this issue. Suppose you have two tables: A and B. Andrew, I hear what you're saying re:forum. I have tried to use the regular Insert and Update statement and also tried the one that have Inner Join, but to no avail. The link between the employees and merit tables is the performance field. Don't assume that you can do it better than Microsoft who has spent already millions to get to be done what you ask.
We want to also update the values of Col 2 and Col 3 only. Hi all, hopefully it's okay to post this here. I did a proof of concept at my last job by looping over a cfquery with a sql insert and compared that to looping over an xml document, then doing the insert via sql parsing and table to table inserts. This table however, has one column with usernames, emails and account numbers mixed. A value of zero 0 means the table is dropped and created again. Yea but not with a joined table. If the value of the f column in the A table equals the value of the f column in the B table, it combines data from a1, a2, b1, b2, columns and includes this row in the result set.
Similar thing happened to me. This is for academic purpose. Taking your inner join queries to the next level will require you to invest more time, but will provide you with faster results and less clutter in your database. The tracks table associated with the albums table via albumid column. I am only confuse for the hard coded one.
