2513 A data row is too long.
The length of the row specified by the caller is greater than SysMaxRow, the maximum length allowed for any row in the database. The row could be either one specified directly by the user, or an intermediate results row required for query processing.

This indicates that a row is too long. Query processing often requires intermediate results rows that are longer than the data being selected. For example, ORDER BY and GROUP BY columns require sort keys that increase intermediate results row size.
Reduce the size of row required. Fewer or smaller columns, or less complex queries may solve the problem. Otherwise, contact support personnel.
