Given the following text where the whitespace between words is a single tab character. one two three four five six seven eight nine Let's imagine we want to replace this with: update some_table set val1 = '#col3' where key1 = '#col1' and key2 = '#col3' where the '#colN' refers to the column in the above text. A valid expression would be: ^([^\t]*)\t([^\t]*)\t([^\t]*)$ However, when this is used the replaced text becomes: update code_mstr set code_cmmt = 'three' where code_fldname = 'one' and code_value = 'two';update code_mstr set code_cmmt = 'six' where code_fldname = ' four' and code_value = 'five';update code_mstr set code_cmmt = 'nine ' where code_fldname = ' seven' and code_value = 'eight'; Which is because the replacement is being greedy and spanning several lines. If we change the search pattern to be: ^(.*)\t(.*)\t(.*)$ The replacement becomes: update code_mstr set code_cmmt = 'three' where code_fldname = 'one' and code_value = 'two'; update code_mstr set code_cmmt = 'six' where code_fldname = 'four' and code_value = 'five'; update code_mstr set code_cmmt = 'nine' where code_fldname = 'seven' and code_value = 'eight'; Which is correct, however; these two expressions have different greedy treatment which is confusing and seemingly unpredictable.
