[PATCH] SQL parser : differentiate quoting of string literals from identifiers
|Reported by:||Even Rouault||Owned by:||warmerdam|
To avoid any ambiguities and more conformant to SQL, string literals should be single-quoted, and identifiers (column/table names) unquoted or surrounded by double-quote charachter if conflicting with reserved keywords.
The attached patch implements this, as well as the necesserary fixes in the test suite. This obviously shows the impact of the patch to user practices...
