I need to search through various large T-SQL scripts and find all references to database objects which has [Database].[SchemaName].[Table|View|StoredProcedure] pattern.
I'm using notepad++ to search folders containing the target scripts. Could someone help me out with a regular expression to identify references to database objects that use the pattern described above. For example:
[MyDB].[MySchema].Employee
MyDb.MySchema.Employee
MyDb.[MySchema].uspGetEmployee
[MyDb].MySchema.vwEmployee
are all candidates to be found because they have the three layers.
[MySchema].Employee is not a candidate because it doesn't follow the pattern of [Db].[Schema].[Object].
Thank you.
This regex:
(\w+|\[\w+\])\.(\w+|\[\w+\])\.\w+
Is as simple as it gets. It means:
A word, or a word in between [] ((\w+|\[\w+\]));
Followed by a dot (\.);
Followed by a word, or a word in between [] ((\w+|\[\w+\]));
Followed by a dot (\.);
Followed by a word (\w+).
Check out this demo and see (and test) what it matches.
Naturally, just place it in the Find what: text field of notepad++ search box.

I've implemented auto completion to a combobox like this article shows. Is it possible to make it search for substrings instead of just the beginning of the words?
http://www.codeproject.com/Articles/2371/IAutoComplete-and-custom-IEnumString-implementatio
I haven't found any way to customize how IEnumString/IAutoComplete compares the strings. Is it possible?
The built in search options help a bit but it is complete chaos. To find instring matches you need to set flag AcoWordFilter. But this will prevent from numbers being matched!! However, there is a trick to get the numbers to match: preced with a double-quote as in "3 to find a string containing or starting with "3". Some more chaos? In the AcoWordFilter you also need to prefix other characters not considered part of a "word", eg. you need to prefix parentheses with a " but then you will not find parentheses at the first position!
So the solution is either to create your own implementation of IAutoComplete or offer the user to switch between the modes (a bit awkward).
I dont think that the MS engineers are especially proud of such chaos. How about one more option: AcoSearchAnwhere?
After retrieving the Edit control's IAutoComplete interface, query it for an IAutoComplete2 interface. Calling its SetOptions member you can disable prefix filtering by specifying the ACO_NOPREFIXFILTERING AUTOCOMPLETEOPTIONS.
This is available on Windows Vista and later. If you need a solution that works with pre-Vista versions, you'll have to write your own.
I am working on an application to search for and build a list of all the times a string (or variable of) is in a text file. Kind of like a Find All function in a text editor that I can build a list with the info that is found, such as
S350
S250
S270
S5000
What can I use to do this search? It will have one value that does not change (The S in this case) followed by up to 4 digits
RegEx seems like a good choice.
Something like.. S(\d{1,4})? might work for you.
Expresso is my preferred regular expression composer.
I'm working on a translator that will take English language text (as user input into a UITextView) and (with a button press) replace specific words with alternatives. I have both the English words in scope plus their alternatives in separate Arrays (englishArray and alternativeArray), indexed correspondingly.
My challenge is finding an algorithm that will allow me to identify a word in the input text (a UITextView) ignoring characters like <",.()>, lookup the word in englishArray (case insensitive), locate the corresponding word in alternativeArray and then use that word in place of the original - writing it back to the UITextView.
Any help greatly appreciated.
NB. I have created a Category extending the NSArray functionality with a indexOfCaseInsensitiveString method that ignores case when doing an indexOfObject type lookup if that helps.
Tony.
I think that using an NSScanner would be best to parse the string into separate words which you could then pass to your indexOfCaseInsensitiveString method. scanCharactersFromSet:intoString: using a set of all the characters you want to ignore, including whitespace and newline characters should get you to the start of a word, and then you could use scanUpToCharactersFromSet:intoString: using the same set to scan to the end of the word. Using scanLocation at the beginning and end of each scan should allow you to get the range of that word, so if you find a match in your array, you will know where in your string to make the replacement.
Thanks for your suggestion. It's working with one exception.
I want to capture all punctuation so I can recreate the original input but with the substituted words. Even though I have a 'space' in my Character Set, the scanner is not putting the spaces into the 'intoString'. Other characters I specify in the Character Set such as '(' and ';' are represented in the 'intoString'.
Net is that when I recreate the input, it's perfect except that I get individual words running into each other.
UPDATE: I fixed that issue by including:
[theScanner setCharactersToBeSkipped:nil];
Thanks again.
I have url, for example:
http://i.myhost.com/myimage.jpg
I want to change this url to
http://i.myhost.com/myimageD.jpg.
(Add D after image name and before point)
i.e I want add some words after image name and before point using regex.
What is the best way do it using regex?
Try using ^(.*)\.([a-zA-Z]{3,5}) and replacing with \1D\2. I'm assuming the extension is 3-5 alphanumeric numbers but you can modify it to suit. E.g. if it's just jpg images then you can put that instead of the [a-zA-Z]{3,5}.
Sounds like a homework question given the solution must use a regex, on that assumption here is an outline to get you going.
If all you have is a URL then #mathematical.coffee's solution will suit. However if you have a chunk of text within which is one or more URLs and you have to locate and change just those then you'll need something a little more involved.
Look at the structure of a URL: {protocol}{address}{item}; where
{protocol} is "http://", "ftp://" etc.;
{address} is a name, e.g. "www.google.com", or a number, e.g. "74.125.237.116" - there will always be at least one dot in the address; and
{item} is "/name" where name is quite flexible - there will be zero or more items, you can think of them as directories and a file but this isn't strictly true. Also the sequence of items can end in a "/" (including when there are zero of them).
To make a regex which matches a URL start by matching each part. In the case of the items you'll want to match the last in the sequence separately - you'll have zero or more "directories" and one "file", the latter must be of the form "name.extension".
Once you have regexes for each part you just concatenate them to produce a regex for the whole. To form the replacement pattern you can surround parts of your regex with parentheses and refer to those parts using \number in the replacement string - see #mathematical.coffee's solution for an example.
The best way to learn regexs is to use an editor which supports them and just experiment. The exact syntax may not be the same as NSRegularExpression but they are mostly pretty similar for the basic stuff and you can translate from one to another easily.
Is there a way to limit the Filtered word match in the dotnetnuke forum to whole words only. For example, if the word 'bum' is a filtered word replaced by a '~' then the word 'bumble bee' is also affected becoming '~ble bee'
I'd like to limit to a full word match rather than a partial. Any help is most appreciated.
Thanks
Its been awhile but one trick I have done is but a space in the word you are filtering so it has to be bum_ not bumble (treat the underline char as a space in this post) -
Note: this used to work if DNN forum has changed to strip spaces off words in filter list this might not work anymore
