Pipe SQL select statement results to script
Hello
I would like to perform a select from a oracle table and return those values to my shell script
For example:
site=head -1 $infile | cut -c1-15 | awk '{printf "s%", $0}
sqlplus -s /nolog |& #Open pipe to sql
select col1, col2, col3, col4
from oracle_table
where col5 = $site
exit # return to UNIX Script
perform various operations using the retuned values col1, col2, col3 & col4 from the select statement
Thank you

stag-selectall_xml
SELECTALL_XML(1p) User Contributed Perl Documentation SELECTALL_XML(1p)
NAME
stag-selectall_xml - Query all elements from database with an XML output
SYNOPSIS
stag-selectall_xml [-d <dbi>] [-f file of sql] [-nesting|n <nesting>] SQL
DESCRIPTION
This script will query a database using either SQL provided by the script user, or using an SQL templates; the query results will be turned
into XML using the DBIx::DBStag module. The nesting of the XML can be controlled by the DBStag SQL extension "USE NESTING..."
EXAMPLES
stag-selectall_xml -d "dbi:Pg:dbname=mydb;host=localhost"
"SELECT * FROM a NATURAL JOIN b"
TEMPLATES
A parameterized SQL template (canned query) can be used instead of specifying the full SQL
For example:
stag-selectall_xml -d genedb /genedb-gene gene_symbol=Adh
Or:
stag-selectall_xml -d genedb /genedb-gene Adh
Or:
stag-selectall_xml -d genedb /genedb-gene gene_symbol@=Adh,dpp,bam,indy
A template is indicated by the syntactic shorthand of using a slash to precede the template name; in this case the template is called
genedb-gene. the -t option can also be used.
All the remaining arguments are passed in as SQL template parameters. They can be passed in as either name=value pairs, or as a simple list
of arguments which get passed into the template in order
To use templates, you should have the environment variable DBSTAG_TEMPLATE_DIRS set. See DBIx::DBStag for details.
LISTING AVAILABLE TEMPLATES FOR A DB
stag-selectall_xml -d mydb -h
LISTING VARIABLES FOR A TEMPLATE
stag-selectall_xml /genedb-gene -h
ENVIRONMENT VARIABLES
DBSTAG_DBIMAP_FILE
A file containing configuration details for local databases
DBSTAG_TEMPLATE_DIRS
list of directories (separated by :s) to be searched when templates are requested
COMMAND LINE ARGUMENTS
-h|help
shows this page if no other arguments are given
if a template is specified, gives template details
if a db is specified, lists templates for that db
use in conjunction with -v for full descriptions
-d|dbname DBNAME
this is either a full DBI locator string (eg dbi:Pg:dbname=mydb;host=localhost) or it can also be a shortened "nickname", which is then
looked up in the file pointed at by the environment variable DBSTAG_DBIMAP_FILE
-u|user USER
database user identity
-p|password PASS
database password
-f|file SQLFILE
this is a path to a file containing SQL that will be executed, as an alternative to writing the SQL on the command line
-n|nesting NESTING-EXPRESSIONS
a bracketed expression indicating how to the resulting objects/XML should be nested. See DBIx::DBStag for details.
-t|template TEMPLATE-NAME
the name of a template; see above
-wh|where WHERE-CLAUSE
used to override the WHERE clause of the query; useful for combining with templates
You can append to an existing where clause by using the prefix +
-s|select SELECT-COLS
used to override the SELECT clause of the query; useful for combining with templates
-rows
sometimes it is preferable to return the results as a table rather than xml or a similar nested structure. specifying -rows will fetch
a table, one line per row, and columns separated by tabs
-pre SQL
a piece of SQL is that is executed immediately before the main query; e.g.:
-pre "SET search_path=myschema,public"
-o|out FILE
a file to output the results to
-w|writer WRITER
writer class; can be any perl class, or one of these
xml [default]
sxpr
lisp S-Expressions
itext
indented text
-color
shows results in color (sxpr and itext only)
-show
will show the parse of the SQL statement
