Re: Using Pg JDBC driver with perl DBD::JDBC

Line 1195 and this comment…

// If given user provided column names, quote and escape them.

// This isn't likely to be popular as it enforces case sensitivity,

// but it does match up with our handling of things like

// DatabaseMetaData.getColumns and is necessary for the same

// reasons.

I have confirmed that the statements I execute are not working. It does look like what you suggest based on the warning. I just can’t find it in the source which is why I’m asking about the postgres jdbc source.

Thanks

looks like perl DBD is putting a returning statement in. So does JDBC

Hi,

I currently use DBD:Pg for interfacing perl and Postgres, but I want to try using the Postgres jdbc driver with DBD::JDBC. I use DBD::JDBC v 1.49 for several other databases. They all work without an issue except for the Pg driver

I installed postgresql-9.4.1208.jar to use against my postgres database at version 9.4.2.

DBD:JDBC server runs the driver fine

9605 29:19 java -DVTIER=127.0.0.1 -Djdbc.drivers=org.postgresql.Driver -Ddbd.port=9005 com.vizdom.dbd.jdbc.Server

I can also make a connection.

my $url = qq{jdbc:postgresql://localhost:5432/www};
my $dsn = qq{dbi:JDBC:hostname=127.0.0.1;port=9005;url=$url};

my $dbh = DBI->connect($dsn,'user', 'password',{PrintError=>0,RaiseError=>0,AutoCommit=>1});
my $application_logging = qq/SET application_name = ‘Sales Reporting'/;

But when any statement is executed I get the message below but with a different Position number
$dbh->do($application_logging);

DBD::JDBC::db do warning: ERROR: syntax error at or near "RETURNING"
Position: 40

The statements seem to be working.

I’ve searched through the JDBC.pm and DBI.pm source for a clue. I don’t find the “RETURNING” string.

My question for the group is whether or not this message is coming from the JDBC driver? This message is a warning and an error so I’m not sure it can be ingored. It is returned with or without PrintError=>1

Thank you, Mike
