Purpose
The OMIT command excludes specified columns from Field Mode reports for data-returning SQL statements.
Syntax
where the following is true:
- n
- Specifies the number of columns to omit, ordered from left to right, and separated by a comma or one space.
The value of n can range from 1 to 2048.
Usage Notes
The OMIT command is useful to underscore a field or to cause a pagebreak at a field not to be displayed.
The initial values of the OMIT command are OFF and ALL by default. If ON or OFF is not selected, BTEQ sets OMIT to ON ALL.
To produce several reports during the same BTEQ session, and change the OMIT specifications for each report, specify .SET OMIT OFF before supplying each new OMIT command specification.
Turn off any prior OMIT command specifications to display previously omitted columns on subsequent reports.
The OMIT setting only affects the output for Field Mode, not Record Mode, Indicator Mode, or Multipart Indicator Mode.
The OMIT command can be used in a Teradata SQL macro.
Example 1 – OMIT
The following example shows the results of using the OMIT command specifications three ways:
- With the default configuration
- With all columns omitted
- With one column (i.e., column 2) omitted
database workforce; .set defaults .set format on .heading "Example 1" .set omit off select deptno ,Loc(Title 'Department Location') from department order by deptno ; .set format on .set defaults .set omit off .set omit on all .heading 'Example 2' = 1 .set defaults .set format on .set omit off .set omit on 2 .heading 'Example 3' = 1 .defaults .set format off .logoff .exit
BTEQ Responses
In the first select operation, with the OMIT command specifications set to the default configuration, BTEQ returns the following response:
*** Query completed. 5 rows found. 2 columns returned. Example 1 DeptNo Department Location ------ ------------------- 100 NYC 300 NYC 500 ATL 600 CHI 700 NYC
In the second select operation, with the OMIT command specifications set to ON ALL, BTEQ returns the following response:
*** Query completed. 5 rows found. 2 columns returned. Example 2
In the third select operation, with the OMIT command specifications set to omit column two, BTEQ returns the following response:
*** Query completed. 5 rows found. 2 columns returned. Example 2
In the third select operation, with the OMIT command specifications set to omit column two, BTEQ returns the following response:
*** Query completed. 5 rows found. 2 columns returned. Example 3 DeptNo ------ 100 300 500 600 700
Example 2 – OMIT instigated by a macro
The Example 1 OMIT command in a Teradata SQL macro appears as:
ECHO '.SET OMIT ON 2';
