I find the code is sometimes many per line and often over many lines, which is good: formatted normally in a beautified, easily viewed, structured indentation. This sed ensures one nicely flattened delete per line. The \t in this is to be replaced with a real tab:
Code:
sed -n '
  :loop2
  /delete from/{
    :loop
    /;/!{
      N
      b loop
     }
    s/\n/ /g
    s/;/ ;\
/
    s/\t/ /g
    s/  */ /g
    P
    s/.*\n//
    b loop2
   }
 ' $sql_file | grep -i "delete from $table "

For some regex libs, \< and \> are \b, a pesudo-character before or after a word, i.e., white space or punctuation not _ or either end of the line.
Code:
^word,word:word;word word\tword-word$

so I made the spaces real and singular around every word. I might be mangling constants with spaces, but that is OK in this context.
