Datatype Synonyms

SQL Server uses different names for some datatypes than those that are specified by the ANSI-92 standard. Microsoft has accommodated this by providing synonyms for these. However, even if you specify the synonym, it will be translated and stored as the equivalent SQL Server datatype. The available synonyms are listed in Table 12.7.
