This Oracle tutorial explains how to use the Oracle / PLSQL REGEXP_SUBSTR function with syntax and examples. This function, introduced in Oracle 11g, will allow you to extract a substring from a string using regular expression pattern matching REGEXP_SUBSTR. Syntax. Description of the illustration regexp_substr.gif. Purpose. REGEXP_SUBSTR extends the functionality of the SUBSTR function by letting you search a string for a regular expression pattern. It is also similar to REGEXP_INSTR, but instead of returning the position of the substring, it returns the substring itself.This function is useful if you need the contents of a match. In diesem Oracle-Lernprogramm wird erläutert, wie Sie die Oracle/PLSQL REGEXP_SUBSTR-Funktion mit Syntax und Beispielen verwenden. Beschreibung Die Oracle/PLSQL-Funktion REGEXP_SUBSTR ist eine Erweiterung der SUBSTR-Funktion. Mit dieser Funktion, die in Oracle 10g eingeführt wurde, können Sie mit einem regulären Ausdrucksmustervergleich einen Teilstring aus einem String extrahieren. Syntax.

The REGEXP_SUBSTR() function returns a portion of source string that matches the regular expression. The data type of the result string can be either VARCHAR2 or CLOB and its character set is the same as the source string. Examples. Suppose, we have the following string: 'This is a regexp_substr demo' If you want to get the fourth word of the above string, you use the REGEXP_SUBSTR() function. Examples: Oracle REGEXP_SUBSTR function . The following example examines the string, looking for the first substring bounded by commas. Oracle Database searches for a comma followed by one or more occurrences of non-comma characters followed by a comma and returns the substring, including the leading and trailing commas. SELECT REGEXP_SUBSTR('the web development tutorial, from w3resource.

SELECT REGEXP_SUBSTR('hello to you', '.o',1,2) FROM sysibm.sysdummy1 The result is 'to'. Return the third string occurrence which matches any character preceding a 'o'. SELECT REGEXP_SUBSTR('hello to you', '.o',1,3) FROM sysibm.sysdummy1 The result is 'yo'. Related reference. Regular expression control characters. The REGEXP_SUBSTR function is the advanced version of the classic SUBSTR function, allowing us to search for strings based on a regular expression pattern. This function returns a portion of the source string based on the search pattern but not its position. The substring returned by this function can be either of VARCHAR2 or CLOB data type in the same character set as that of the input source.

Syntax Where, TD_SYSFNLIB : the name of the database Read Mor REGEXP_SUBSTR REGEXP_SUBSTR( stringTerm, patternString [, startInt] ) REGEXP_SUBSTR ( stringTerm, patternString , startInt) Returns a substring of a string by applying a regular expression start from the offset of a one-based position. Just like with SUBSTR, if the start index is negative, then it is relative to the end of the string. If not specified, the start index defaults to 1. Example. In Oracle, SUBSTR function returns the substring from a string starting from the specified position and having the specified length (or until the end of the string, by default). In SQL Server, you can use SUBSTRING function, but it does not allow you to specify a negative start position, and the substring length must be specified
