Summary Title Accommodation

In the previous example, BTEQ was unable to accommodate the display of the first summary title because no room existed for it. Increasing the first column's width does not alleviate this problem. BTEQ does not place a summary title in result line space that is designated for a summary-text aggregate value. To alleviate this constraint, select empty column(s) that are aligned to make available dedicated result line space. The next example shows before and after results using this technique.

Example  

Assume a table called FruitTrees exists in the current database and a report is needed showing how many trees are ripe, plus the related yields. The table displays the following columns and values:

  TreeId      Fruit             Yield  Status
  ----------  ----------  -----------  ----------
  CITR01      ORANGE               10  NOT RIPE
  CITR02      ORANGE               30  NOT RIPE
  CITR03      ORANGE              500  RIPE
  POME01      APPLE               100  NOT RIPE
  POME02      APPLE                80  NOT RIPE
  POME03      APPLE               400  RIPE
  POME04      APPLE                20  RIPE

The script contains these BTEQ commands and SQL statements, which do not specify selection of any empty columns:

  .SET SUPPRESS ON 1
  SELECT   Status
         , Fruit
         , Yield
         , TreeId
  FROM     FruitTrees
  GROUP BY Status, Fruit, Yield, TreeId
  ORDER BY Status, Fruit, Yield
  WITH     COUNT(Fruit)   (TITLE 'Trees'    )
         , SUM  (Yield)   (TITLE 'Yield'    ) BY Status, Fruit
  WITH     COUNT(Status)  (TITLE 'Tot Trees')
         , SUM  (Yield)   (TITLE 'Tot Yield') BY Status
  ;

BTEQ Response

  Status       Fruit              Yield  TreeId
  -----------  -----------  -----------  ----------
  NOT RIPE     APPLE                 80  POME02
               APPLE                100  POME01
               -----------  -----------
        Trees            2          180
  
               ORANGE                10  CITR01
               ORANGE                30  CITR02
               -----------  -----------
        Trees            2           40
  
  -----------               -----------
            4    Tot Yield          220
  
  RIPE         APPLE                 20  POME04
               APPLE                400  POME03
               -----------  -----------
        Trees            2          420
  
               ORANGE               500  CITR03
               -----------  -----------
        Trees            1          500
  
  -----------               -----------
            3    Tot Yield          920

Example  

In the prior example, BTEQ finds space for only two of the four summary text titles. If the script is changed, as shown in the next example, to include selection of empty columns that create result space for the titles, BTEQ is able to include them. Note that the selected width for the empty columns is important. The titles are truncated if the width is too small.

  .SET SUPPRESS ON 1,2
  SELECT   ' ' (CHAR(9)) (TITLE ''), Status
         , ' ' (CHAR(5)) (TITLE ''), Fruit
         , ' ' (CHAR(5)) (TITLE ''), Yield
                                   , TreeId
  FROM     FruitTrees
  GROUP BY Status, Fruit, Yield, TreeId
  ORDER BY Status, Fruit, Yield
  WITH     COUNT(Fruit)   (TITLE 'Trees'    )
         , SUM  (Yield)   (TITLE 'Yield'    ) BY Status, Fruit
  WITH     COUNT(Status)  (TITLE 'Tot Trees')
         , SUM  (Yield)   (TITLE 'Tot Yield') BY Status
  ;
