[jira] Updated: (DERBY-522) ERROR X0Y79 raised when adding comments using "--" before sql queries with Network Client
[ http://issues.apache.org/jira/browse/DERBY-522?page=all ]
Kathey Marsden updated DERBY-522:
---------------------------------
Summary: ERROR X0Y79 raised when adding comments using "--" before sql queries with Network Client (was: ERROR X0Y79 raised when adding comments using "--" before sql queries with Network Cleint)
Description:
Comments before a select statement Throws exception with Network Client
For Example a statement like the one below in the attached program with throw an exception.
stmt.execute("-- This is a comment \n Select c11 from TAB1");
org.apache.derby.client.am.SqlException: Statement.executeUpdate() cannot be called with a statement that returns a ResultSet.

at CommentBeforeSelect.main(CommentBeforeSelect.java:35)
$
To reproduce run the attached program
java CommentBeforeSelect
was:
// Bug 5398 - comments in select statement Throws exception
stmt.execute("-- This is a comment \n Select c11 from TAB1");
ResultSet rs = stmt.getResultSet();
The problem comes I think because the client looks at the SQL statement and sends it as EXCSQLIMM , because it does not start with SELECT, VALUES, etc.
EXCSQLIMM cannot be used for a statement that returns result sets.
Client needs to treat the statement as a select and handle it properly.
Note:
Currently IJ currently has code to strip out the comments for Network Client so the issue will not reproduce with IJ.
