XSQL error when trying to insert record

Question

hi,
I encounter a problem using INSERT statement in xsql:query action. If I try to use INSERT statement in my xsql page like this:
<xsql:ze_action bean="TaskentryIn">
<xsql:query>
INSERT
Grundtab( Datum,Startzeit,Endzeit)
VALUES
('{@date}',{'@begin}','{@ende}')
</xsql:query>
</xsql:ze_action>
I always get this xsql-error:
Statement.executeQuery - No result sets were produced by 'INSERT...'
So far so good, I think this shouldn't be an error rather a warning.
But this is not my primary problem.
Anyway the record is inserted in the DB. But since I call the above <xsql:query>, from within my own action handler, I call a sendRedirect() to my next page after the <xsql:query> tag was processed.
After sendRedirect(), when I am on my next page, I check the DB for the inserted records, and it shows up that the insert was made two times, so I have two identically records in my DB.
If I am not sendRedirect() to the next xsql page, then the insert is only made once. So I assume that there is a problem if an xsql-error occurs and afterwards a sendRedirect().
I am using the same way to make my SELECT statements and I dont have any trouble with them. Only when I use INSERT.
Any adive or help is appreciated.
Peter

Answer 1

<xsql:query> is only for queries.
Use <xsql:dml> for a DML statement.
