When using SQL*Loader to load vector data for search applications, what is a critical consideration regarding the formatting of the vector data…

SQLLoader in Oracle 23ai supports loading VECTOR data from CSV files, requiring vectors to be

formatted as text. A critical consideration is enclosing components in curly braces (A), e.g., {1.2, 3.4,

5.6}, to match the VECTOR type’s expected syntax (parsed into FLOAT32, etc.). FVEC (B) is a binary

format, not compatible with CSV text input; SQLLoader expects readable text, not fixed offsets.

Sparse format (C) isn’t supported for VECTOR columns, which require dense arrays. SQLLoader

doesn’t normalize vectors automatically (D); formatting must be explicit. Oracle’s documentation

specifies curly braces for CSV-loaded vectors.
