I used inner join in a coding test with SQL, but the output is not aligned. What could be the issue?

edit

There could be multiple reasons for the output being not aligned after using inner join in SQL. Some of the common issues are:

1. Data types of the joined columns are different. For example, if one column is of type VARCHAR and the other is of type INT, then there could be issues with aligning the data.

2. Null values in the joined columns. If one or more columns have null values, then it can cause misalignment of data.

3. Truncation of data. If the joined columns have data that is too large to fit in the output, then the data can get truncated, causing misalignment.

4. Formatting issues. If the output is formatted incorrectly, it can cause issues with alignment.

To resolve the issue, you can try the following:

1. Check the data types of the joined columns and ensure that they are of the same type.

2. Handle null values by using functions such as COALESCE or ISNULL.

3. Increase the column width to accommodate larger data.

4. Check the formatting of the output and fix any issues with alignment.
