-1104: Too complicated SQL statement (KB-stack overflow) 

Explanation:

Within the system, more elements of an internal structure are needed to represent the SQL statement than are available.

User Action:

Simplify the SQL statement or split it into several SQL statements.

If this is not possible, check whether the database parameter PACKET_SIZE can be increased, because the size of the internal structure depends on the size of that parameter. The structure size will be adapted from a certain limit value of PACKET_SIZE.
