What is Nlssort?
Description. The NLSSORT function is used to replace a character string with the equivalent sort string used by the linguistic sort mechanism. In the case of a binary sort, the sort string is the same as the input string. In linguistic sort, each character in a string is replaced by some other binary values.
What is BLOB and CLOB in Oracle?
BLOB stands for binary large objects, which are used for storing binary data, such as an image. CLOB stands for character large objects, which are used to store string data too large to be stored in a VARCHAR column.
What is enum in SQL?
