LEFT JOIN gets all records from the LEFT linked and the related record from the right table ,but if you have selected some columns from the RIGHT table, if there is no related records, these columns will contain NULL.
The fact that when it says INNER JOIN, you can be sure of what it does and that it's supposed to be just that, whereas a plain JOIN will leave you, or someone else, wondering what the standard said about the implementation and was the INNER/OUTER/LEFT left out by accident or by purpose.

LEFT JOIN vs. LEFT OUTER JOIN in SQL Server - Stack Overflow
Cross join: merge(x = df1, y = df2, by = NULL) Just as with the inner join, you would probably want to explicitly pass "CustomerId" to R as the matching variable. I think it's almost always best to explicitly state the identifiers on which you want to merge; it's safer if the input data.frames change unexpectedly and easier to read later on.
The result of join is always a string, but the object to be joined can be of many types (generators, list, tuples, etc). .join is faster because it allocates memory only once. Better than classical concatenation (see, extended explanation). Once you learn it, it's very comfortable and you can do tricks like this to add parentheses.
