UltraLite data types

• an_SQL_code    A data type for holding SQL error codes.

• ul_char    A data type representing a character. If the operating system uses Unicode, ul_char uses two bytes per character. For single-byte character sets, ul_char uses a single byte per character.

• ul_binary    A data type representing one byte of binary information.

• ul_column_num    A data type for holding a number indicating a column of a table or query. The first column in the table or query is number one.

• ul_fetch_offset    A data type for holding a relative number in a ULCursor object.

• ul_length    A data type for holding the length of a data type.

• DECL_DATETIME    A type for holding date and time information in a SQLDATETIME structure, which is defined as follows:

  typedef struct sqldatetime {
     unsigned short year; /* e.g. 1999 */
     unsigned char month; /* 0-11 */
     unsigned char day_of_week; /* 0-6 0=Sunday */
     unsigned short day_of_year; /* 0-365 */
     unsigned char day; /* 1-31 */
     unsigned char hour; /* 0-23 */
     unsigned char minute; /* 0-59 */
     unsigned char second; /* 0-59 */
     unsigned long microsecond; /* 0-999999 */
  } SQLDATETIME;

  DECL_DATETIME is also used in embedded SQL programming. Other embedded SQL data types with named DECL_type are not needed in C++ API programming.

• UL_NULL    A constant representing a SQL NULL.
