Binary large object (BLOB) data in SAP Sybase IQ is stored in columns of data type LONG BINARY or BLOB.
An individual LONG BINARY data value can have a length ranging from zero (0) to 512TB (terabytes) for an IQ page size of 128KB, or 2PB (petabytes) for an IQ page size of 512KB. (The maximum length is equal to 4GB multiplied by the database page size.) To accommodate a table with LONG BINARY data, an IQ database must be created with an IQ page size of at least 128KB (131072 bytes).
A table or database can contain any number of LONG BINARY columns up to the supported maximum columns per table and maximum columns per database, respectively.
LONG BINARY columns can be either NULL or NOT NULL and can store zero-length values. The domain BLOB is a LONG BINARY data type that allows NULL.
You cannot construct a non-FP index on a LONG BINARY column.
Prefetching is disabled, if the result set contains BLOB columns.
Modify LONG BINARY columns using the UPDATE, INSERT, LOAD TABLE, DELETE, TRUNCATE, SELECT...INTO and INSERT...LOCATION SQL statements. Positioned updates and deletes are not supported on LONG BINARY columns.
You can insert an Adaptive Server Enterprise IMAGE column into a LONG BINARY column using the INSERT...LOCATION command. All IMAGE data inserted is silently right-truncated at 2147483648 bytes (2GB).
