How to retrieve blob or clob data where length > ?

IDS 11.50.FC5 AIX 5.3 We are currently in the process of moving much of our data stored in blob spaces to smart blob spaces. The columns that were defined as BYTE columns are now either BLOB or CLOB datatypes. In the past, I was able to retrieve data based on the length of the data stored in the BYTE column with the following sql. select c_case_number from images where length(b_image_byte) > 45000 This column is now stored in smart blob spaces and defined as a blob data type. Running this same sql, I receive the following error: select c_case_number from images where length(b_image_byte) > 45000SQL Error (-674): Routine (length) can not be resolved. Error Position: Ln: 3 Col: 7 Any idea on how to retrieve blob or clob data based on the length of the blob column? Thanks, Susan
