Hello,
Im trying to use regexp with simplesql and Im getting this error:
sql example:
Found out that regexp is not defined by default in sqllite and you need to add it as a user function:
stackoverflow.com/questions/5071601/how-do-i-use-regex-in-a-sqlite-query
"SQLite does not contain regular expression functionality by default.
It defines a REGEXP operator, but this will fail with an error message unless you or your framework define a user function called regexp(). How you do this will depend on your platform."
www.sqlite.org/c3ref/create_function.html
Something like this:
docs.microsoft.com/en-us/dotnet/standard/data/sqlite/user-defined-functions
thank you for your wonderful product. hope you can provide a solution!
