regex - How to find {min,max} repeats regular expression patterns in Visual Studio or SSMS "Find and Replace"? -

-

i knew have in regular expression syntax world.

*the syntax {min,max}, min positive integer number indicating minimum number of matches, , max integer equal or greater min indicating maximum number of matches.

so {0,} same , , {1,} same +

http://www.regular-expressions.info/repeat.html

but how can use in sql server management studio or visual studio "find , replace" window. find related microsoft syntax in msdn. like:

[0-9]^4 matches 4-digit sequence.

the visual studio regex implementation (in versions until vs 2010) nonstandard 1 least, , doesn't have feature. can spell out:

* or @: match 0 or more of preceding expression

+ or #: match 1 or more of preceding expression

^n: match n repetitions of preceding expression

so a{2,4} you'd have use a^4|a^3|a^2 (see polygenelubricant's comment explanation why need in descending order).

more recent versions of vs support entire set of .net regexes.
