Core designer certificate

ccomes3007

Hi,

I am trying to do the project for the core designer certificate. I have load the 3 dataset but when I'm doing the join between the three dataset I have 955 rows and not 985 rows as it say in the hand-on instructions.

There is any problem with dataset?

Thank you for your help.

Hi @ccomes3007
, I can confirm that you should indeed have 985 rows in the output to the Join. Since you have fewer rows than expected, you might want to check:

- Are you correctly filtering for the required years?

- Are you using the correct type of Join?

- Has Step 2 been completed? Do you have numeric columns stored as numbers?

Hi @SeanA
Sean, I have the same issue, but getting 2940 rows. I have tried different join methods, I have filtered for years before the join as well as after the join and checked it in the output dataset, numeric columns are stored as int, but whatever I do, I cannot get less than 2940 rows in the output dataset

Any suggestions, please?

I checked everything but I'm getting 230 rows after filtering

Hi @Ashish2309 I've double checked again on a cloud instance just to be sure. The 3 tips above are still the best guide to making sure this output is correct.
