Got error in joining two tables: Left and right key variables 'Date' and 'Date' include cells containing non-string values.

Hi, I have two tables a and b. Both have a column Date as datenum. When I use left join, I got this error: "Left and right key variables 'Date' and 'Date' include cells containing non-string values." One table has 600 records; the other table is very large and has 25000 records. What can be the problem here and how to fix this?
Thanks for any input.

The error seems clear: you are trying to use a variable that is not supported as a key. You say that you have a datenum variable, the error suggests that that is not the case, that you have a cell array containing datenums.
If you are using anything like a recent version of MATLAB, you will likely be better of using datetimes.
