Question

I’m using the Ruby mysql module.

I want to print out the results of a query and include the column names. I’m having trouble finding the method to give me an array of these names. I have the values as shown below.

result = my.query(“select * from foo”)

result.each do |row| puts row.join(‘,’) end

Thanks for the help!

Answer 1

 result.fetch_fields.each_with_index do |info, i|
       printf "--- Column %d (%s) ---\n", i, info.name
       printf "table:            %s\n", info.table
       printf "def:              %s\n", info.def
       printf "type:             %s\n", info.type
       printf "length:           %s\n", info.length
       printf "max_length:       %s\n", info.max_length
       printf "flags:            %s\n", info.flags
       printf "decimals:         %s\n", info.decimals
     end
