change EPStatement expression at runtime

[Arnold, Maik]

Hi @all,

Is it possible to change the EPStatement expression at runtime?
I didn't find any method like myEPStatement.setText( "new Expression String")

Or should I delete the statement and create it new with the new expression?

Thanks a lot
Maik

Statements have a lifecycle and are not conceptually designed to be modified arbitrarily at runtime
You can indeed create new statements instead at runtime, and also use prepared statement if you use many variants of a similar common abstract statement.

Hi all,

I am searching for a way to get (list) all the EPStatements.
I see that there is a way to get the statement names (epService.getEPAdministrator().getStatementNames()),
but I need to get the EPL statements (select ....).
Do you how I can do this?

Thank you,
Laura

Something like this maybe :

List<String> stmtNames =
Arrays.asList(epService.getEPAdministrator().getStatementNames());

for (String name : stmtNames) {
    String stmt = epService.getEPAdministrator().getStatement(name).getText();
}
