I'm focusing on the error message you received: unterminated
dollar-quoted string. Since the code works via iBATIS in the unit test,
it seems iBATIS is not the issue. Try switching your unit test to use
TransactionAwareDataSourceProxy and see if it fails. If so, that will
narrow your problem identification to working with that proxy.
If changing delimiters doesn't work, PostgreSQL can work without dollar
quoted strings. See the documentation for alternatives.

You are correct. I can create the stored proc via iBatis via a unit
test, but when I run it as a deployed webapp on Tomcat (using Java btw)
it fails. So perhaps iBatis isn't to blame here, but hopefully I can be
pointed in the right direction. The only thing that is really different
between the unit test and the deployed webapp is the datasource. I'm
using Spring so the unit test uses
org.springframework.jdbc.datasource.DriverManagerDataSource and the
webapp uses
org.springframework.jdbc.datasource.TransactionAwareDataSourceProxy.
I'm not sure what you mean by the delimiter comment. The $ isn't the
problem, its the semi-colon. AFAIK the semi-colon use to end a
statement is not configurable and within a stored proc there could
obviously be many semi-colons.

I'm not following your situation. You say it works fine through a
unit test but fails in Tomcat. By fine, do you mean that you can
create your stored proc via iBATIS in your unit test? If so and it
fails on your webapp, then I'm guessing your webapp is using $ signs
for other purposes. You don't mention what language your webapp is
using.
At any rate, if you webapp language uses $ signs for its own
purposes, PostgreSQL allows you to define whatever character you
wish for delimiters.

Hi all,
I am trying to accomplish an obscure use-case. I am trying to
implement the generation of a Postgres function (aka stored
procedure)
via iBatis. I am using an<insert> tag and simply have the standard
PostgreSQL syntax for creating the funciton within it. I
created all
this functionality through unit tests and everything worked
great. As
soon as I tried to run the application from within my webapp
(Tomcat)
however, it bailed with an "unterminated dollar-quoted string at or
near..." error. After some debugging I found out that it was
truncating the query after the semi-colon.
I guess this makes sense as iBatis uses prepared statements and can
therefore only execute one SQL statement at a time. So in this
case I
am executing one SQL statement which is a 'CREATE FUNCTION' but
within
that statement there are multiple SQL statements (i.e. the code
within
the function). iBatis doesn't seem to be able to handle this though
and simple searches through the generated SQL statement and stops at
the first semi-colon.
I am wondering if there are any work-arounds to this problem? The
only solution that I can think of is to pass off the generation
of my
custom function to another postgres function, and simply call that
function with the necessary arguments.
Regards,
Collin
