A little late to the game and a lot of good info has already been provided. Whenever I create a temporary table for a specific process, as soon as the process is completed, I drop the table. Like others have suggested, before I create the temporary table I DROP the table with the specific error messages turned off before and turned on back on after creation. During testing I comment out the DROP table command so I can look at the table and make sure the correct data is there as needed. Once the code is ready to go into the production database all the DROP commands are uncommented so they are back to being active. Works well for me but I am usually the only one coding so the conflict is not an issue. Temporary tables are created in memory locally so they are created every fast.

Hard to believe in my decades of programming that this is the first time this has happened. Just wondering if other programmers have tips on this situation for the future. And I'm kinda bored this afternoon so thought I would post. History: I work on this company's stuff with another programmer. We work independently, each of us handling different "areas" of the business. The company's contact himself also does a bit of programming. So 3 of us writing programs. I write a new program today, works great for me, he keeps claiming it doesn't work for him, giving him my "no data to report" message. He exits and comes back in, never works. I finally ask him exactly the process he's going thru, and I find out that he will run another program immediately before running this program. Aha, a clue. Guess what. In that other program (written by the other programmer), he creates a temp table (and doesn't drop it) using the same column name that I have in my temp table, but as a different datatype! So my temp table was never created because of the structure error, and it reports no data! So what's the best way to prevent this? I was thinking of things like: 1. Each of us using temp column names using our initials (like: ktQty INT). But even with that, there's no guarantee that I'll remember I used a "ktQty" as a Double once, and as an Integer another time. 2. I could search program code for occurrences of each "new" temp column name I want to use to see if any other program uses that name. 3. I could only use permanent column names, altho using the permanent name "Qty" is not as descriptive as a temp column name like: tmpQtyToShipByMonthend But in reality there's 3 "easy" things I could do: 1. We could drop our temp tables at the end of our programs. None of us do this. I like leaving them around in case I run something from the menu and want to get to the R> prompt to see temp table data. Do you all drop temp tables? 2. After every "create temp table" do a "select ... from sys_tables" to see if the temp table exists. Seems the easiest, doesn't it? Again, do any of you routinely do this? 3. Or.. I can figure that since this has happened once in the >20 yrs that I've worked on that account, figure that it's most likely not going to happen again so don't worry about it. Just some Monday musings......
