Brief_I/O

   VARIABLE  I/O  DESCRIPTION
   --------  ---  --------------------------------------------------
   selidx     I   Index of parent column in SELECT clause.
   row        I   Row to fetch from.
   elment     I   Index of element, within column entry, to fetch.
   idata      O   Integer element of column entry.
   null       O   Flag indicating whether column entry was null.
   found      O   Flag indicating whether column was present in row.

Detailed_Input

   selidx      is the SELECT clause index of the column to fetch
               from. The range of selidx is from 0 to one less than
               the number of columns in the SELECT clause.

   row         is the output row containing the entry to fetch
               from. The range of row is from 0 to one less than
               the number of rows satisfying the previous query.

   elment      is the index of the element of the column entry
               to fetch. The normal range of elment is from 0 to
               one less than the size of the column's entry, but
               elment is allowed to exceed the number of elements in
               the column entry; if it does, found is returned
               as SPICEFALSE. This allows the caller to read data
               from the column entry in a loop without checking the
               number of available elements first.

               Null values in variable-sized columns are
               considered to have size 1.

Detailed_Output

   idata       is the requested element of the specified column
               entry. If the entry is null, idata is undefined.

               If idata is too short to accommodate the requested
               column entry element, the element is truncated on
               the right to fit idata.

   null        is a logical flag indicating whether the entry
               belonging to the specified column in the specified
               row is null.

   found       is a logical flag indicating whether the specified
               element was found. If the element does not exist,
               found is returned as SPICEFALSE.

Parameters

   None.

Exceptions

   1)  If the input argument `elment' is less than 0, the error
       SPICE(INVALIDINDEX) is signaled by a routine in the call tree of this
       routine and `found' is returned SPICEFALSE. However, `elment' is allowed
       to be greater than or equalt to the number of elements in the specified
       column entry; this allows the caller to read data from the column entry
       in a loop without checking the number of available elements first. If
       `elment' is greater than or equal to the number of available elements,
       `found' is returned SPICEFALSE.

   2)  If `selidx' is outside of the range established by the last query
       passed to the EK search engine, the error SPICE(INVALIDINDEX) is
       signaled by a routine in the call tree of this routine and `found' is
       returned SPICEFALSE.

   3)  If the input argument `row' is less than 0 or greater than or equal
       to the number of rows matching the query, the error
       SPICE(INVALIDINDEX) is signaled by a routine in the call tree
       of this routine and `found' is returned SPICEFALSE.

   4)  If the specified column does not have integer type, the error
       SPICE(INVALIDTYPE) is signaled by a routine in the call tree
       of this routine.

   5)  If this routine is called when no E-kernels have been loaded,
       the error SPICE(NOLOADEDFILES) is signaled by a routine in the
       call tree of this routine.

Files

   The EK "query and fetch" suite of functions reads binary `sequence
   component' EK files. In order for a binary EK file to be
   accessible to this routine, the file must be `loaded' via a call
   to the function eklef_c.

   Text format EK files cannot be used by this routine; they must
   first be converted by binary format by the NAIF Toolkit utility
   SPACIT.

Particulars

   This routine allows retrieval of data from integer columns.

   This routine returns one element at a time in order to save the
   caller from imposing a limit on the size of the column entries
   that can be handled.

Examples

   The numerical results shown for these examples may differ across
   platforms. The results depend on the SPICE kernels used as
   input, the compiler and supporting libraries, and the machine
   specific arithmetic implementation.

   1) Perform a query on an EK file that contains a database with
      the Supplementary Engineering Data Records of the Viking
      Project in order to retrieve the IMAGE_NUMBER values (integer
      numbers) that correspond to the images with IMAGE_NUMBER
      smaller than a given value, ordered by IMAGE_NUMBER.


      Use the EK kernel below to load the information from the
      original Supplementary Engineering Data Record (SEDR) data
      set generated by the Viking Project.

         /.
         The table "VIKING_SEDR_DATA" has a column
         "IMAGE_NUMBER" of double precision values.

         Define a set of constraints to perform a query on
         all loaded EK files (the SELECT clause). In this
         case select the column "IMAGE_NUMBER" from table
         "VIKING_SEDR_DATA" sorted by "IMAGE_NUMBER".

            Fetch the character data. We know the query returned
            one column and the column contains only scalar data,
            so the index of all elements is 0.

   2) This example demonstrates how to fetch integer values
      from a column in three different cases: single values,
      variable-size arrays and static-size arrays.

      Create an EK that contains a table TAB that has the following
      columns:

         Column name   Data Type   Size
         -----------   ---------   ----
         INT_COL_1     INT         1
         INT_COL_2     INT         VARIABLE
         INT_COL_3     INT         3


      Issue the following query

          query = "SELECT INT_COL_1, INT_COL2, INT_COL3 FROM TAB"

      to fetch and dump column values from the rows that satisfy the
      query.

      Note that after run completion, a new EK file exists in the
      output directory.


   3) Query the EK system and fetch data matching that query.

      The program shown here does not rely on advance
      knowledge of the input query or the contents of any loaded EK
      files.

      To simplify the example, we assume that all data are scalar.
      This assumption relieves us of the need to test the size of
      column entries before fetching them. In the event that a
      column contains variable-size array entries, the entry point
      eknelt_c may be called to obtain the size of column entries to
      be fetched. See eknelt_c for an example.


      Use the EK kernel below to load the information from the
      original Supplementary Engineering Data Record (SEDR) data
      set generated by the Viking Project.

         vo_sedr.bdb

      Use the LSK kernel below to load the leap seconds and time
      constants required for the conversions.
