Summary:
SQL queries that are longer than 254 characters will not execute correctly. This problem is caused by SQLAppend() which gets called automatically for large queries. This function reuses the original buffer and does not terminate the appended string correctly. Depending on the contents of the original buffer, the query may or may not execute. 

Solution:
This problem has been fixed in 3.4/4.2 Service Pack E.
