IBM Tivoli NetView for z/OS Programming: Pipes - IBM notice

column is null or contains data. This information might be required to process the
result of a table query containing columns that can have the null value (no data).
The following example shows how indicator words are suppressed in the output
record; the query seen by DB2 is the same in both the preceding and the following
examples. The remaining two unprintable bytes contain the length, in binary, of the
varying field. Use EDIT to discard these columns.

As an alternative to the previous method, the following example shows how to use
EDIT to format binary data:
/* Query the test table without formatting */
Signal on novalue
’PIPE’,
’SQL noindicators select * from jtest ’,
’|SEPARATE’,
’|EDIT 1.3 1 9.2 c2d substr 2.* right 2511.*8’,
’|console’
Exit RC

In this example, EDIT supports conversion between character and binary or
floating point and constructs varying length character fields.
Note: The SEPARATE stage creates individual data records for the EDIT stage. If you
omit the SEPARATE stage, only the first data record found appears in the
output.
SQSELECT formats a query against a sample table in the following example:
’pipe NETV SQSELECT * from jtest | COLLECT | CONSOLE’

Querying a Database and Formatting the Results
Use SQSELECT to issue a DB2 query and converts the result to an easy-to-read,
printable format with column headings.

( SQL options )
DB2 SELECT operands
Note the following when using SQSELECT:
v If the first nonblank character is a left parenthesis, the string up to the first right
parenthesis is processed as options. The remainder of the argument is processed
as a DB2 SELECT statement. The default SQL option is NOCOMMIT and
implies the plan is not closed.
v Code SQSELECT as a first stage in a pipe:
