SSIS deployment failed - working with files
This isn't a problem with your data - it is a problem with your package. Usually, this is a problem with the size of your query.

It appears that internally, SSIS uses a varchar(8000) value somewhere that could actually use a varchar(max) value. When you run up against this limit, you get this ambiguous error.

There are several ways you can approach this. You can shorten your query (by removing excessive whitespace, replacing spaces with tabs, compacting indents, etc). 

You can also split your query out into multiple variables or parameters, then concatenate the pieces back together with an expression task before executing the query.

Depending on the query, you could also convert it into one or more stored procedures or views, and call those within your package.

But if you keep the query inside the package, you need to reduce its length (or its piece's lengths) to less than 8000 characters.  Have fun.

Have fun - nothing is more fun than refactoring a query.
