Ant sql task - print executed query and result with PostgreSQL - postgresql

Question

I'm trying to print executed query and also result of the query on PostgreSQL. I have simple ant sql task, using standard postgresql JDBC driver.
<?xml version="1.0"?>
<project name="Ant SQL task" default="sql">
<target name="sql">
<echo>Ant SQL task</echo>
<sql
driver="org.postgresql.Driver"
url="jdbc:postgresql://hostname:port/database"
userid="user"
password="password"
src="script.sql"
print="yes"
>
</sql>
</target>
</project>
The script.sql containts just
select 1 as test;
I'm getting this output:
info:
[sql] Executing resource: script.sql
[sql] test
[sql] 1
[sql]
[sql] 0 rows affected
[sql] 1 of 1 SQL statements executed successfully
I would like to print the select query in the output like this:
info:
[sql] Executing resource: script.sql
[sql] select 1 as test;
[sql] test
[sql] 1
[sql]
[sql] 0 rows affected
[sql] 1 of 1 SQL statements executed successfully
Is there a way to include the select query in the output?

Answer 1

1.) Set loglevel to DEBUG (2) for the jdbc. Except now you don't have too little info in your log file, but too much.
2.) Append your queries a little:
SELECT 1 as foo, (SELECT query FROM pg_stat_activity);
foo | query
-----+--------------------------------------------------------
1 | SELECT 1 as foo, (SELECT query FROM pg_stat_activity);
(1 row)
Note that this will give you all running queries, not just the current one. You can narrow it down by one of the many columns in pg_stat_activity, but that's probably unnecessary unless this is a busy system. Set ApplicationName in your connection parameters if you decide to do that.
3.) Add lines to script.sql that manually repeat the next query:
SELECT 'SELECT 1;';
SELECT 1;
SELECT 'SELECT 2;';
SELECT 2;
4.) Ditch the ant sql module and use exec to run psql -e -f script.sql instead:
SELECT 1;
?column?
----------
1
(1 row)
You can omit the row count with -P footer=OFF.
