How to join tables without creating a new table?LS,
I want to add data from a table to a main table. This can be easily done by using the "join" option from the tables menu. However, this generates a new datatable while I want to add data to the main data table.
Now I have to close the original main table and than overwrite the original file with all potential risks.
Is thisd possible, and how (note that I know that JMP uses scripts, but I am not familiar with building my own scripts
thanks
Kees
Re: join tables without creating a new tableIf you use
Tables=>Update
it will not create a new tableRe: join tables without creating a new tableStrange, in my case it still creates a new table.
Re: join tables without creating a new tableHi Peter,
I have seen the option (I am using JMP13.1 since a few months).
Not sure if it will work; data needs to come from different locations on our internal network, and multiple people will work with the merged file.
The help indicates that this option is specially designed to prevent creating massive files that slow down pc’s / laptops. Up till now, our files are still relatively small (<1000 rows and <50 columns).
I will look into this option, but hoped for a more simple solution J
Cheers

Re: join tables without creating a new tableHY Phil,
Thanks for your reply. Unfortunately, and indeed unexpectedly because I also expected "update" to update the whole table, this command updates columns AND stores the update in a new table.
Thanks

Re: join tables without creating a new tableIf you are running JMP/JMP Pro version 13 the new virtual join capability might be something worth looking at. Especially if the size of the joined data table takes up a relatively large RAM footprint on your computer. Here's the link to the virtual join portion of the JMP online documentation:

Re: join tables without creating a new tableIn the Join dialog box, there is a check box, that allows you to "Update main table with data from second table"

Re: join tables without creating a new tableHi,
Instead of JOIN. Use the UPDATE option in the Tables Menu.
Re: join tables without creating a new tableThis creates a new data table per the JMP 18.1 documentation:
Update main table with data from second table
Data in the original table are updated with data in columns that have the same names. The results are displayed in a new data table.
I think this didn't used to create a new data table. Was this changed recently?
I found a JMP Wishlist item for this: Tables join: option to update main table. Please upvote the Wishlist item if you would like to see this implemented in JMP.
Re: join tables without creating a new tableTables=>Join
always creates a new data table.
Tables=>Update
does not create a new table
Re: join tables without creating a new tableYou are looking at the documentation for JOIN DATA TABLES. There is an option when joining tables, to "Update main table with data from second table". This is different from the other function -- UPDATE DATA TABLEs
See the following link for the details: Update Data Tables
Re: join tables without creating a new tableTables => Update does not work for my situation, since it cannot do an Inner or Right Outer Join.
