Setting NLS_SORT to BINARY_CI means SQL operations will use binary value for sorting and ignore the character case. After setting the parameters, given above, the string comparison will ignore the character case. Since we can’t set these parameters at the database level, we can create the ...

“Deterministic” means that equality can be established by byte-for-byte equality comparison. In that sense, case-insensitive collations are non-deterministic, since 'Case' = 'case', even though they are not encoded as the same bytes. The table would be defined as 1 2 3 4 CREATE TABLE...
