This control enables users to specify whether all consecutively repeated values in reports are to be replaced with space characters.
where the following is true:
- Column numbers are ordered from left to right and separated by commas.
The value of n can range from 1 to 2048.
Use the SUPPRESS command to simplify reports by eliminating all repetitive values from the specified columns.
BTEQ always displays the first occurrence of a new value in each column, regardless of the setting of the SUPPRESS command options. After that, if the SUPPRESS command option is set to ON, BTEQ replaces those values with space characters in the specified columns. (Each row containing a new value can be preceded by one or more blank lines, depending on the settings of the SKIPLINE and SKIPDOUBLE commands options.)
If a page break occurs between suppressed values, BTEQ presents the value in the first row of the next page and then suppresses the remaining occurrences of that value.
The initial configuration of the SUPPRESS command options are OFF and ALL. If ON or OFF are not specified, or column numbers are not included, BTEQ sets SUPPRESS to ON ALL.
If several reports are produced during the same BTEQ session, and different SUPPRESS command options are used for each report, first specify .SET SUPPRESS OFF ALL before using each new SUPPRESS command.
When using the SUPPRESS and SKIPLINE commands together, the same columns specified for the SUPPRESS command are specified for the SKIPLINE command.
For example, using the following syntax:
.set suppress on 1,2,3,4,5 .set skipline on 1,2,3
BTEQ sets columns 4 and 5 for the SKIPLINE command. To specify SKIPLINE for columns 1, 2, and 3, use the following syntax:
.set suppress on 1,2,3,4,5 .set skipline off 4,5
Also, using the SHOW CONTROLS command after using the SUPPRESS command, BTEQ resets the SKIPLINE columns to the same as the SUPPRESS columns.
The SUPPRESS setting only affects the output for Field Mode, not Record Mode, Indicator Mode, or Multipart Indicator Mode.
The SUPPRESS command is valid in an SQL macro.
Example 1 – SUPPRESS
The following example returns the selected information first with the SUPPRESS command option set to OFF, then set to ON for column 1:
database workforce; .defaults .format on .heading 'Suppress off' select deptno ,name from employee order by deptno ; .defaults .format on .heading 'Suppress on 1' .suppress on 1 = 1 .format off .logoff .exit
*** Query completed. 21 rows found. 2 columns returned. Suppress off DeptNo Name ------ ------------ 100 Peterson J 100 Chin M 100 Greene W 100 Moffit H 300 Russell S 300 Leidner P 300 Phan A 500 Inglis C 500 Carter J 500 Watson L 500 Smith T . . (etc) *** Query completed . 21 rows found. 2 columns returned. Suppress on 1 DeptNo Name ------ ------------ 100 Peterson J Chin M Greene W Moffit H 300 Russell S Leidner P Phan A 500 Inglis C Carter J Watson L Smith T . . (etc) *** Query completed . 21 rows found. 2 columns returned. Suppress on 1 DeptNo Name ------ ------------ 100 Peterson J Chin M Greene W Moffit H 300 Russell S Leidner P Phan A 500 Inglis C Carter J Watson L Smith T . . . (etc)
Example 2 – SUPPRESS
To suppress columns 1 and 2 from one report, and then in the same BTEQ session, suppress column 3 of the next report, use the following SUPPRESS command for the first BTEQ report:
.SET SUPPRESS 1, 2
Then, use the following SUPPRESS commands to reconfigure the SUPPRESS command options for the next BTEQ report:
.SET SUPPRESS OFF ALL .SET SUPPRESS 3
Example 3 – SUPPRESS Instigated By a Macro
The SUPPRESS command in an SQL macro appears as:
ECHO '.SET SUPPRESS 1,2';
