I have created a CLR in a SQL server 2005 database. It is a simple regular expression user defined function that will check if a pattern exists in the string I pass into the function.
The dot net code I use in the CLR is shown below:
Return System.Text.RegularExpressions.Regex.IsMatch("Input", "pattern")
This returns a bit value of 1 if a match is found.
The pattern I am using is
+(Create|Alter) +(Proc|Procedure) +
What I want this to do is find any cases of “create or alter” “procedure or proc” regardless of the case. How can I get the expression to ignore case?
I have tried
/ +(Create|Alter) +(Proc|Procedure) +/i
but this doesn’t work.
EDIT: I have looked around on the internet and used various suggestions. None of which have worked or I have done them wrong. If someone could give me a pattern that will ignore the case that would be much appreciated!
Answer:
What i was trying to achieve was a regular expression that ignores case. Dot Net does have parameters that can be passed in to set ignore case however it being in a CLR means i do not have the ability to pass the parameters in to the function.
The pattern that achieves this is : (?i) +(Create|Alter) +(Proc|Procedure) +
You can use the inline “case-insensitive” modifier
(?i):
