Program Considerations
Table 15: Predefined System Variables (continued)
System Variable
&SYSTIME
&SYSUPDCNT[n]
&SYSUSER
&SYSAPLYCNT[n]
&SYSNOAPLYCNT[n]
&SYSRJCTCNT[n]
Description
8-character time format hh:mm:ss
Gives total updates to all target tables for import n. If n is not given, it
gives the total updates done to all the target tables for all the imports.
The maximum value of n is 4.
Client system dependent: CMS user ID, z/OS Batch user ID. (z/OS-batch
returns user ID only when a security package such as RACF, ACF2, or
Top Secret has been installed).
Number of records applied for import n. If n is not given, it gives the
total number of records applied for all imports.
Number of records not applied for import n. If n is not given, it gives the
total number of records not applied for all imports.
Number of records rejected for import n. If n is not given, it gives the
total number of rejected records of all the imports. The maximum value
of n is 4.
Date and Time Variables
&SYSDATE, &SYSDATE4, &SYSTIME, and &SYSDAY reflect the time when Teradata TPump
begins execution. The original values are restored at restart. These values are character data
types and should not be used in numeric operations. System variables cannot be modified,
only referenced.
The values returned by &SYSDAY are all in upper case. Monday, for example, is returned as
'MON':
0003 .IF '&SYSDAY' NOT = 'MON' THEN;
14:10:28 - FRI JUL 30, 1993
UTY2402 Previous statement modified to:
0004 .IF 'FRI' NOT = 'MON' THEN;
0005 .RUN FILE UTNTS39;
0006 .ENDIF;
This example causes the RUN FILE command to be executed every day but Monday. It can be
seen from this example that any of the system variables can be used as the subject condition
within an IF/ELSE/ENDIF command construct. This allows creation of a script forcing certain
events to occur or tasks to operate in a predetermined sequence, based on the current setting
of the variable.
As another example, if we create the following table:
.SET TABLE TO 'TAB&SYSDAY';
Create table &TABLE (
Account_Number INTEGER NOT NULL,
Last_Name VARCHAR(25),
First_Name VARCHAR(25),
Street_Address VARCHAR(30),
City VARCHAR(20),
State CHAR(2),
