    BigInt

    *

    * Values are returned as a string. This is because values can exceed 53 bits of significant data, which is greater than a * Javascript number type can represent as an integer. *

    *
    2. *

    Numerical, Decimal

    *

    * For input parameters, default precision is 18 and default scale is 0. Maximum supported precision is 19. *

    *
    3. *
  3. *

    VarChar, NVarChar

    *

    * varchar(max) and nvarchar(max) are also supported. *

    UniqueIdentifier

    *

    * Values are returned as a 16 byte hexadecimal string. *

    *

    * Note that the order of bytes is not the same as the character representation. See * Using uniqueidentifier Data * for an example of the different ordering of bytes. *
