The REGEXP_SUBSTR function, much like the SUBSTR function, extracts part of a string


REGEXP_SUBSTR(source_string, pattern[, position [, occurrence[, match_parameter]]])


In the following SQL query, the string that matches the pattern , [^,]*, is returned. The regular expression searches for a comma followed by a space; then zero or more characters that are not commas, as indicated by [^,]*; and lastly looks for another comma. The pattern will look somewhat similar to a comma-separated values string.
