Creating a database using ant

Hello,

I am trying to write get ant to drop and create a database. I tried to
use the sql task but recieved the following error:

java.sql.SQLException: ERROR: DROP DATABASE cannot run inside a
transaction block

Here is my ant task:

<sql driver="${db.postgresql.driver}"
userid="${rootuser}"
password="${rootpassword}"
url="${db.postgresql.url}"
onerror="stop"
autocommit="false"
src="${db.postgresql.sqlScripts.dir}/dropDatabase.sql">
<classpath>
<path refid="run.classpath"/>
</classpath>
</sql>

Although autocommit is false, it looks like the sql script is still
executing within a transaction. Does anyone know a workaround?

I also tried runing the dropdb command directly, but (from my
understanding) ant cannot receive user input during execution. As a
result, I can't supply a password to dropdb (at least I don't know how
to do it).

<exec executable="${postgres_bin.dir}/dropdb"
failonerror="true">
<arg value="-U"/>
<arg value="${rootuser}"/>
<arg value="--password"/>
<arg value="mydb"/>
</exec>

Many thanks,

-Nathan

You got it the wrong way around. autocommit=false gets you a transaction, i.e.
statements are *not* automatically committed when you have that set. You want
autocommit=true. I've done it (creating databases in ant) and it works...

JdV!!

Try with autocommit="true".
