[teiid-issues] [JBoss JIRA] (TEIID-2896) Add TEXTTABLE function capabilities to interpret fixed width data file content that is shorter than the defined line length

[Barry LaFond (JIRA)]

    [ https://issues.jboss.org/browse/TEIID-2896?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12973835#comment-12973835 ] 

Barry LaFond commented on TEIID-2896:
-------------------------------------

So what was not clear to me was what these data files actually look like so the UI (TEIIDDES-2091) could help users create these *views*

My understanding is that there are standard CSV files and *complex* CSV files
* CSV files contain multiple rows of data containing the same #columns and column data
* complex CSV will contain different *types* of rows, with each type representing a mini-CSV file format

It appears that you cannot create a TEXTTABLE() statement that crosses *types*, so Designer would need to help users choose the *type* to create a single *view* as Van just stated?

> 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.
