Kylin Soong commented on TEIID-3346:
------------------------------------

This may not a bug, it seems it's default design behavior which can not use Dot as column name, Model name, or any nameinsource string, I met this error several time.

> In case a Delimited Flat file , contains a "Dot" character in any of the column names, we get an issue during Virtual Data Base deployment -
> Root cause -
> org.teiid.api.exception.query.QueryParserException: TEIID31100 Parsing error: Encountered "'UTF-8') COLUMNS [*]\"name.full\"[*] STRING," at line 1, column 126.
> Invalid simple identifier format: [name.full]
>  
> The query is : SELECT A."name.full",A."surname" FROM (EXEC tabwithdot.getFiles('tab.csv')) AS F, TEXTTABLE(TO_CHARS(F.file,'UTF-8') COLUMNS "name.full" STRING,"surname" STRING delimiter '    ' quote ' ' HEADER) AS A
>  
> Please note, that although the column name [name.full], is enclosed in Double Quotes, still this issue is observed.
> If there was instead any other special character, that works successfully.
