Create new system function to dump temp table contents to file.
-----------------------------------------------------------------
Key: TEIID-962
URL:
https://jira.jboss.org/browse/TEIID-962
Project: Teiid
Issue Type: Feature Request
Components: Query Engine
Environment: All
Reporter: Ken Johnson
Assignee: Steve Hawkins
A requirement to produce a CSV file reflecting the contents of a query result set so it
can be subsequently FTP'd or email'd. In Nov 07 implemented this feature using the
exec connector, a shell script and mods to JDBCISQL.
Suggested capability: function will take the following parameters:
- Temp table name as string
- Target file name (path qualified) as string
- Delimiter as string
When invoked, the specified temp table contents will be written out to the specified file
using the specified delimiter to separate the column values.
This generic capability will allow the CSV file thats needed and subsequently process it
with other UDF functionality as necessary.
Open questions:
1. How does file path behave in a clustered environment? Is it relative to the MM Server
install dir or fully qualified?
Suggest this feature remain undocumented for the short term.
