Adolfo Ochagavía updated CALCITE-5067:
--------------------------------------
Description:
In MySQL it is possible to use "LANGUAGE" as a variable name. The example below
shows the difference between language (treated as a variable) and other
keywords (which raise a syntax error):
{code:java}
mysql> SELECT LANGUAGE;
ERROR 1054 (42S22): Unknown column 'LANGUAGE' in 'field list'
mysql> SELECT ALTER;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use near
'ALTER' at line 1{code}
In other words, it would be great if the following code succeeded instead of
throwing an exception:
{code:java}
var config = SqlParser.config().withLex(Lex.MYSQL);
var parser = SqlParser.create("SELECT foo", config);
var node = parser.parseQuery();{code}
