RE: Hello, and need help
The execute tag is meant for updates, inserts and deletes. What you
probably want to use is the resultSet tag.
sql:resultSet id=myRS
%
for( int i = 0; i val.size(); i++ )// What is val???
{
% sql:getColumn position=%=i%/ %
}
%
/sql:execute
I think you're trying to print all the values that are returned from your
query. I'm unsure of the origin of the variable 'val'. The resultSet tag
will loop through all the rows by default, I assume the 'for loop' is meant
to loop through all the fields in each given row in the result, thus
val.size() should return the number of fields you're selecting in your where
clause.

Hi everyone, Im new to the list so good to meet you.
Any pointers on why the following code is disallowed, and a quick way to
code around it? Apparently prepared statements do not allow run-time
resolution of the query string.
sql:query
select * from orders where %= where %
//where contains the where clause, with columnname=?
repeated.
//this build a dynamic query with varying number of
elements
/sql:query
sql:execute
% for(int i = 0; i val.size(); i++){ %
sql:setColumn position=%
out.write(String.valueOf(i)); %
%= val.elementAt(0) %/sql:setColumn

RE: Hello, and need help
What im actually trying to accomplish is two things:
- create a dynamic prepared statement each time so I can add where
clauses to it.
- use of the stmt instead of a normal query because I don't want to mess
with figuring out if the where clause item needs to be quoted or not
etc.
val is a vector with all the values want to populate the
preparedstament with... but apparently it doens tlike you to have
variables ere and wants this data to b static.
I didn't show the full tagset earlier, it is encompassed by a
preapredstatement tag.
sql:preparedStatement id=stmt1 conn=conn1
%-- set the SQL query. note the lack of quotes around the name
value --%
sql:query
select * from orders where %= where %
/sql:query
sql:execute
%for(int i = 0; i val.size(); i++){ %
sql:setColumn position=%= i %
%= val.elementAt(0) %/sql:setColumn
%} %
/sql:execute
/sql:preparedStatement

Change the section of dbtags.tld for the setColumn tag to have the value
yes in the rtexprvalue tag, and restart your server.

I think this what you're looking for. Hope it helps.
