the match & the split are done in one operation.
there's no loop or pasted expressions, the "or" part is done by the regex engine, which is most of the time some compiled code: can't beat that in pure python.regular expression is compiled at start, so it's as fast as it can be.This is an optional parameter There are many flags values we can use. flags: The expression’s behavior can be modified by specifying regex flag values. Temp = data.split("word1", 1) # that works only on non-regexes BTWĬan be rewritten simply as def bar(data, allWords): re.compile(pattern, flags0) pattern: regex pattern in string format, which you are trying to match inside the target string. This method will recompile the stored procedure in the first run of the stored procedure. Here is a neat trick where you can make your stored procedure for recompilation but not actually execute it.
Now this is a disguised loop with each term hardcoded: def bar(data, allWords): Method 2: sprecompile for Recompile Stored Procedures. (that also works with standard words of course, and it's still worth using regexes because of the | part) So I have a couple types of patterns I am searching for: #literally just a regular word Im fairly comfortable with writing SQL but have never used an OPTION command in a query before and was unfamiliar with the whole concept of plan caches until. Bear with me, I can't include my 1,000+ line program, and there are a couple of questions in the description.
