Extract float from String/Text SQL Server

由 僤鯓⒐⒋嵵緔 提交于 2021-01-28 02:55:03
问题 I have a Data field that is supposed to have floating values(prices), however, the DB designers have messed up and now I have to perform aggregate functions on that field. Whereas 80% of the time data is in correct format,eg. '80.50', sometime it is saved as '$80.50' or '$80.50 per sqm'. The data field is nvarchar. What I need to do is extract the floating point number from the nvarchar. I came accross this: Article on SQL Authority This, however, solves half my problem, or compound it, some

How to remove a line of text in a string in CMake, working around CMake's lack of line-based regex matching?

由 爱⌒轻易说出口 提交于 2021-01-28 02:04:25
问题 I found out that CMake doesn't do RegEx the way I expected. Apparently, others have had this same problem as well. The issue is that CMake is not line-based. When you use the ^ or the $ operators, they work against the entire string, not the start and end of a line. I'm trying to remove all the lines in a file that say #include <blah.h> or #include "blah.h" . To do so, I whipped up a little function: function(deleteinplace IN_FILE pattern) file(READ ${IN_FILE} CONTENTS) string(REGEX REPLACE $

Regex pulling IP and port from string

由 此生再无相见时 提交于 2021-01-28 02:01:22
问题 I'm using Perl to try and pull the IP address and port from a string. The regex I'm trying to use is: s/(sip:)(;.*)// The strings are: sip:255.255.255.255:8080;transport=TCP sip:255.255.255.255:8080 Obviously my regex replace is not working. Can anyone point me to how I would need to write the regex? From those two strings I want to pull this: 255.255.255.255:8080 Meaning the regex needs to match anything that's not that string and replace it with nothing. Note: IP address and port will be

问题 I'm using Spring Data Mongodb and documents like this : { "_id" : ObjectId("565c5ed433a140520cdedd7f"), "attributes" : { "565c5ed433a140520cdedd73" : "333563851" }, "listId" : ObjectId("565c57aaf316d71fd4e4d0a0"), "international" : false, "countryCode" : 33, "deleted" : false } I would like to query my collection to search a value in the attributes object (in the values and not the keys).

php string validation for basiclatin and 1supplement

由 怎甘沉沦 提交于 2021-01-28 02:00:47
问题 I have an xml schema where a description is defined like this: [\p{IsBasicLatin}\p{IsLatin-1Supplement}]{1,1000} and i have to check in PHP that the user input string is valid for this encoding. Checking for the length is easy, but i don't find a way to use preg_match to check for basic latin. I've tried: preg_match('@^\p{IsBasicLatin}+@^\p{IsLatin-1Supplement}+$@u', $string); but it says that there's an unknown property, even using basicLatin or Latin. 回答1: The pattern \p{IsBasicLatin}

Break out of replace global loop

由 做~自己de王妃 提交于 2021-01-28 01:33:44
问题 I have a RegExp, doing a string replace, with global set. I only need one replace, but I'm using global because there's a second set of pattern matching (a mathematical equation that determines acceptable indices for the start of the replace) that I can't readily express as part of a regex. var myString = //function-created string myString = myString.replace(myRegex, function(){ if (/* this index is okay */){ //!! want to STOP searching now !!// return //my return string } else { return

问题 I am struggling writing a Regex for angular ng-pattern to validate a form input field.An example of the possible inputs are below Valid input: @tag1,@tag2,@tag3 @tag1, @tag2, @tag3 @tag1 Invalid Input: @tag 1 @tag 1, @tag2, @tag -3 @ta g1, @t ag2 Basically it should allow comma and comma whitespace, but not allow whitespace in between tags.
