ASE supports three new datatypes:
bigint – an exact numeric datatype designed to be used when the range of the existing int types is insufficient.
unsigned int – unsigned versions of the following signed exact numeric integer datatypes: unsignedsmallint, unsignedint, and unsignedbigint.
unitext – a variable-length datatype for Unicode characters.
The following table describes all new datatypes supported by ASE, SDK Data Providers, and Drivers:
