Updating oracle date fields
Anyhow, in this example, let’s pretend we are going to build a summarized table with order totals for our customers.
But, we only want to use the customers that actually have had a purchase.
But, the syntax example above might not show the whole truth, since we can have a situation like this: In the expanded version of our UPDATE syntax above, the value that we want to update column1 with, actually comes from a different table.
BUT, in this post I really wanted to show you how to update multiple columns in a table at once.
I'm trying to update one of my Oracle tables using Prepared Statements.
There seems to be a problem with my code when I try to update one of the columns that is a Date field.
So, with the syntax shown earlier in mind, let us put things together, and look at some practical examples.
And, some times, rater than using a ginormous INSERT or UPDATE statement, I actually build the records first with mostly empty columns, and then fill in a few columns at the time.Actually, if you mess up on the WHERE line in the last query, you will end up getting the following error message: “ TJ Abrahamsen is the founder and author of Oracle Coder.
