This task describes how to
execute an IMAGE/SQL utility command file in interactive or batch mode.
Getting Ready
An IMAGE/SQL utility command file can be created with a text editor or can be produced as
part of
the logging process.
If you create or edit this file with an editor,
it must be kept unnumbered.
In the following examples, the file UPDATYPE contains the following commands:
SET TURBODB SALES.SERED.ATC
SET SQLDBE PARTSDBE.SERED.ATC
UPDATE TYPE IN CUSTOMER.CREDIT_RATING TO CHAR(4)
EXIT
|
Note that the commands in this command file assume the TurboIMAGE/XL database
is already attached to the DBEnvironment.
If you want to see commands and comments as the command file is executed,
make sure the ECHO option is on.
Performing the Task
The XEQ command allows you to specify a file containing IMAGE/SQL utility commands
as its parameter.
To interactively execute commands listed in a command file, run the IMAGE/SQL utility
by typing RUN IMAGESQL.PUB.SYS,
then issue the XEQ command. Note that in this example ECHO is off.
:RUN IMAGESQL.PUB.SYS

>>XEQ UPDATYPE
Updated information in table CUSTOMER.
:
|
The SALES database is now attached to the PartsDBE DBEnvironment and
data type mapping information has been updated for the CUSTOMER.CREDIT_RATING
column of the INVENTORY table.
You can also issue XEQ commands in batch mode.
The following job stream file contains XEQ commands that execute the commands
in the UPDATYPE
file.
!job JIMSQL,NANCY/KEVIN.ATC/MGR,SERED/ALL
!comment**************************************************************
!comment* This job executes an IMAGESQL command file.
!comment**************************************************************
!
!tell NANCY.ATC; /-->Start JIMSQL for SALES
!
!run IMAGESQL.PUB.SYS
!
!comment**************************************************************
!comment* The UPDATYPE command file contains commands that SET
!comment* the SALES database and the PartsDBE DBEnvironment.
!comment* It then specifies alternative data type mapping for source
!comment* data set fields and exits the IMAGE/SQL utility.
!comment**************************************************************
!
XEQ UPDATYPE
!
!tell NANCY.ATC; /-->End JIMSQL for SALES
!
!eoj

If an error occurs in batch mode, the job terminates.
The remaining commands are flushed.
Task Reference
An IMAGE/SQL command file is an
unnumbered file containing a list of IMAGE/SQL commands.
If commands span more than one line, use an ampersand (&) to continue
the command to the next line.
Task 13, "Logging IMAGE/SQL Utility Commands," shows how to use the IMAGE/SQL utility logging
facility to create and save files containing often-issued IMAGE/SQL utility commands.
For the syntax of the ECHO command, refer to Chapter 4, "IMAGE/SQL Utility Commands."
