Maybe you'll find my suggestion useful: line 69-73: 69 elsif column.to_s.downcase == "sql" 70 # Treat the first 'value' as pure SQL 71 left << values.shift 72 next 73 end adding following line: right.concat(values) after line 71 would allow the usage of questionmark-placeholders in pure SQL strings useful for example for case insensitive stringcompares: c.and 'sql', "upper(columnname) = upper(?)", value Hi Duane,

thanks for your nice plugin.
Maybe you’ll find my suggestion useful:

line 69-73:
69 elsif column.to_s.downcase == “sql”
70 # Treat the first ‘value’ as pure SQL
71 left << values.shift
72 next
73 end

adding following line:
right.concat(values)
after line 71 would allow the usage of questionmark-placeholders in pure SQL strings useful for example for case insensitive stringcompares:

c.and ’sql’, “upper(columnname) = upper(?)”, value

from:
case values.size
raise “No value specified for Condition”

to:
case values.size
when 0
if column.include?(”IS NULL”)
left

I would like to contribute a patch to fix a problem I have encountered regarding handling of array arguments and the IN operator. What is the best way to get the patch to you ? Regards, Andre Hi Duane,

Another question: how do I construct a query of the type and account_type in ('editor','publisher') Thank you in advance. Also, I use the condition builder to add conditions only if certain parameters exist, like: c.and "name", "like", params[:name]+"%" unless params[:name].empty? and sometimes I end up with an empty condition block which produced an error. I remedied this by adding c.and "1",1 at the beginning of the block. Thank you for this simple and elegant tool. -- Andre Thank you, Duane.

Another question: how do I construct a query of the type

and account_type in (’editor’,'publisher’)

Thank you in advance.

Also, I use the condition builder to add conditions only if certain parameters exist, like:

c.and “name”, “like”, params[:name]+”%” unless params[:name].empty?

and sometimes I end up with an empty condition block which produced an error.

I remedied this by adding

c.and “1″,1

at the beginning of the block.

Thank you for this simple and elegant tool.
