The "variable index exceeds table dimensions" error occurs when we try to access a table column that does not exist. This can happen when trying to join two tables with different column names.
To avoid this error, we should make sure that the column names in the two tables match and do not have any duplicate columns. We can use the innerjoin
, outerjoin
, leftjoin
, or rightjoin
functions to join the tables.
Here's an example of how to use the join
function to combine two tables:
main.m562 chars14 lines
Output:
main.m98 chars6 lines
In this example, we get the "Variable index exceeds table dimensions" error because we are trying to join the two tables using different column names. The correct way to join these two tables would be to use the 'ID' column in both tables:
main.m274 chars8 lines
Output:
main.m114 chars10 lines
In this example, we join two tables with the same column names ('ID' and 'Name') and different names ('ID2' and 'Name2') and use the 'ID' column to join the two tables. The resulting table has the columns 'ID', 'Name', and 'Name2'.
