> Key: DERBY-5972
> URL: https://issues.apache.org/jira/browse/DERBY-5972
> Project: Derby
> Issue Type: Bug
> Components: SQL
> Affects Versions: 10.10.0.0
> Reporter: Knut Anders Hatlen
> Assignee: Knut Anders Hatlen
>
> The grammar doesn't accept the OR operator without parentheses in some constructs.
> For example, in a select list:
> ij> create table t(b1 boolean, b2 boolean);
> 0 rows inserted/updated/deleted
> ij> select b1 or b2 from t;
> ERROR 42X01: Syntax error: Encountered "or" at line 1, column 11. (errorCode = 30000)
> Issue the 'help' command for general information on IJ command syntax.
> Any unrecognized commands are treated as potential SQL commands and executed directly.
> Consult your DBMS server reference documentation for details of the SQL syntax supported by your server.
> However, it does not fail if OR is replaced by AND, or if parentheses are used around the OR expression:
> ij> select (b1 or b2) from t;
> 1
> -----
> 0 rows selected
> ij> select b1 and b2 from t;
> 1
> -----
> 0 rows selected
> Similar behaviour is seen in VALUES statements:
> ij> values true or false;
> ERROR 42X01: Syntax error: Encountered "or" at line 1, column 13. (errorCode = 30000)
> Issue the 'help' command for general information on IJ command syntax.
> Any unrecognized commands are treated as potential SQL commands and executed directly.
> Consult your DBMS server reference documentation for details of the SQL syntax supported by your server.
> ij> values (true or false);
> 1
> -----
> true
> 1 row selected
> ij> values true and false;
> 1
> -----
> false
> 1 row selected
