Hello @Bharath_Kumar_Bachin - no SQLCipher doesn’t naively support a regex function. Like the upstream SQLite, if you provide your own regexp() function the keyword should work however:
The REGEXP operator is a special syntax for the regexp() user function. No regexp() user function is defined by default and so use of the REGEXP operator will normally result in an error message. If an application-defined SQL function named “regexp” is added at run-time, then the “X REGEXP Y” operator will be implemented as a call to “regexp(Y,X)”.
See the language specification and create function documentation for more details.
