Subject: sqlt's generated dumper script should quote column names it is selecting from
Date: Wed, 9 May 2007 17:31:16 -0400
To: bug-SQL-Translator [...]
From: Sudish Joseph <sudish [...]>
% perl -e 'use SQL::Translator; print SQL::Translator->version, "\n"' 0.08 perl version 5.8.6, running under Mac OS X 10.4.9 First: this is an awesomely useful tool. Thanks for writing and maintaining it! I generated a data dumper using: sqlt -f MySQL --producer-db-user someone --producer-db-pass omitted -- producer-dsn dbi:mysql:sftest -t Dumper <in.sql > The script is then run as: perl -w One of the tables in the schema has a member named 'from'. Since issues SELECTs with unquoted column names, mysql generates errors like the following: --- DBD::mysql::st execute failed: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'from, to, cc, bcc, subject, date, content_type, content_encode, mime_version, x_' at line 1 at line 828. DBD::mysql::st fetchrow_hashref failed: fetch() without execute() at line 830. --- The SELECT that was issued is: --- select id, message_id, from, to, cc, bcc, subject, date, content_type, content_encode, mime_version, x_mailer, x_sender, x_priority, reply_to, return_path, mail_followup_to, disposition_notification_to, received, create, read from inbox_messages --- The problem here is the unquoted 'from' in the select above. The following statement would work: --- select 'id', 'message_id', 'from', 'to', 'cc', 'bcc', 'subject', 'date', 'content_type', 'content_encode', 'mime_version', 'x_mailer', 'x_sender', 'x_priority', 'reply_to', 'return_path', 'mail_followup_to', 'disposition_notification_to', 'received', 'create', 'read' from inbox_messages --- I fixed this by transforming the code that generates the SELECT from: --- my $sql = 'select ' . join(', ', @{ $table->{'fields'} } ) . " from $table_name" --- to: --- my $sql = 'select ' . join(', ', map { "\'$_\'" } @{ $table-> {'fields'} } ) . " from $table_name" --- The actual template that's used by -t Dumper to generate the code should be changed to match. Thanks, -Sudish
