LIKE is not as powerful, but typically faster than regular expressions. It's probably substantially faster to narrow down the set of candidates with a cheap LIKE expression. Generally, you would use NOT LIKE '__0', but since we already establish LIKE '00%' in the other predicate, we can use the narrower (cheaper) pattern NOT LIKE '000' For example, in the Employee table, we want to filter results and get the only employee whose name starts with character A. We use regular expressions to define specific patterns in T-SQL in a LIKE operator and filter results based on specific conditions. We also call these regular expressions as T-SQL RegEx functions

REGEXP_LIKE function is one of the important regular expression, which is used for regular expression matching.This article will give you idea about different REGEXP_LIKE examples. REGEXP_LIKE function is same as Like operator, which is used for matching of regular expressions The REGEXP_LIKE condition uses the input character set to evaluate strings. If you specify match_parameter values that conflict, the REGEXP_LIKE condition will use the last value to break the conflict. If the match_parameter is omitted, the REGEXP_LIKE condition will use the case-sensitivity as determined by the NLS_SORT parameter

Literals like . are special selectors in regex. So, for a LIKE fragment asdf.qwer% a (python syntax) regex re.match('^asdf.qwer.*$', 'asdfXqwer') would INCORRECTLY match because . means any single character here. You also need to escape any regex-special chars in LIKE fragment before piping to regex LIKE syntax for pattern is simple and supports a small set of wildcards, but does not support the full regular expression syntax. SIMILAR TO syntax for pattern allows a robust pattern matching using the regular expression syntax defined in the ANSI/ISO SQL standard sql documentation: REGEXP. Überprüft, ob eine Zeichenfolge mit einem regulären Ausdruck übereinstimmt (definiert durch eine andere Zeichenfolge) In MySQL, the REGEXP_LIKE() function is used to determine whether or not a string matches a regular expression.. The function returns 1 if the string matches the regular expression provided, and 0 if it doesn't.. Syntax. The syntax goes like this: REGEXP_LIKE(expr, pat[, match_type]) Where expr is the input string and pat is the regular expression for which you're testing the string against A regular expression (abbreviated regex or regexp and sometimes called a rational expression) is a sequence of characters that forms a search pattern, mainly for use in pattern-matching and search-and-replace functions.They can be also used as a data generator, following the concept of reversed regular expressions, and provide randomized test data for use in test databases

SELECT EMPNO FROM EMPLOYEE WHERE REGEXP_LIKE(LASTNAME,'luc+?hes+?i','i') The result is 1 row with EMPNO value '000110'. Example 2: Select any invalid product identifier values from the PRODUCT table. The expected format is 'nnn-nnn-nn' where 'n' is a digit from 0 to 9. SELECT PID FROM PRODUCT WHERE NOT REGEXP_LIKE(pid,'[0-9]{3}-[0-9]{3}-[0-9]{2}') The result is 0 rows because all the product. SQL Function Description; REGEXP_LIKE. This function searches a character column for a pattern. Use this function in the WHERE clause of a query to return rows matching the regular expression you specify. See the Oracle Database SQL Reference for syntax details on the REGEXP_LIKE function. REGEXP_REPLACE . This function searches for a pattern in a character column and replaces each occurrence. REGEXP_LIKE (expr, pat [, match_type ]) Returns 1 if the string expr matches the regular expression specified by the pattern pat, 0 otherwise. If expr or pat is NULL, the return value is NULL. The pattern can be an extended regular expression, the syntax for which is discussed in Regular Expression Syntax
