---------------------------------------
So if you have an example of how you accomplished this, it would be
appreciated.
A column SELECTOR is not valid with fixed width parsing.
Sorry I wasn't paying full attention. What are referring to by this? To clarify
there are two selectors, a row selector and a column selector. Row selectors are
supported in fixed width, but yes column selectors are not. In fixed width column
selectors do not make general sense unless all rows have the same data format. See also
TEIID-2898
As for the test case, you add null to the end of the line, but in the
sample file attached, the actual null column is in the middle.
I'm not sure what you mean.
and part of the problem with the sample is, each type has a different
fixed width.
Generally you want only a single type, so you would use a row selector for only that
type.
Add TEXTTABLE function capabilities to interpret fixed width data
file content that is shorter than the defined line length

Key: TEIID-2896
URL:
https://issues.jboss.org/browse/TEIID-2896
Project: Teiid
Issue Type: Enhancement
Components: Query Engine
Reporter: Van Halbert
Assignee: Steven Hawkins
Fix For: 8.7
Attachments: sample, TEIID-2896.patch
Current behavior is that data lines too short to fit a fixed width data interpretation
produces an error such as "Error: Text parse error: Fixed width line width 35 is
smaller than the expected 60 on text line 1 in file:/tmp/file.csv.". The
customer's use case is interpreting data files from another application which bundles
multiple types of data along with additional descriptive info/metadata about the data
contained within the file. As the error is thrown if any lines after the first interpreted
line are shorter than the summed value of the fixed width columns, they are unable to
query the file. The customer wishes for the ERROR to be suppressed and the query to return
the data independent of whether it fits the fixed width criteria and potentially to be
able to filter the data being retrieved.
