Replaces one value in a string with another. If string is already longer than length, then it is truncated (on the right). Returns the number of bytes required to hold the given value.įills up string to size length by prepending the characters fill (a space by default). This function is identical in functionality to LENGTH the function name is supported for compatibility. Returns the number of characters in a string value. Words are sequences of alphanumeric characters separated by non-alphanumeric characters. If no match found and default not specified, returns null.ĭECODE(3, 1,'One', 2,'Two', 3,'Three', 'Not found')Ĭonverts the first letter of each word to upper case and the rest to lower case. When match found, returns corresponding parameter pair, expr1b, expr2b, etc. Same as argument types of expr1b, expr2b., defaultįinds first match of expr with expr1a, expr2a, etc. Some of them are used internally to implement the SQL-standard string functions listed in the above table.ĪSCII code of the first byte of the argument.ĭECODE(expr, expr1a, expr1b. More string manipulation functions are available and are listed in the following table. If set isn't specified, a blank space is used as default. Removes all the characters specified in set from the right of a given string. Removes all the characters specified in set from the left of a given string. Removes the longest string containing only the characters (a space by default) from the start/end/both ends of the string. SUBSTRC('abc',3) (assuming a double-byte character set) SUBSTR4('abc',3) (assuming a double-byte character set) SUBSTR2('abc',3) (assuming a double-byte character set) SUBSTRB('abc',3), assuming a double-byte character set. Same as SUBSTR except start and count are in number of bytes. If count isn't specified, the string is clipped from the start till the end. INSTRB('PETER PIPER PICKED a PECK of PICKLED PEPPERS','PICK', 1, 2)Įxtracts substring starting from start and going for count characters. Returns the position of the specified occurrence of set within the string, beginning at start. INSTRB('PETER PIPER PICKED a PECK of PICKLED PEPPERS','PICK', 14) Returns the position of the set within the string, beginning at start. INSTRB('PETER PIPER PICKED a PECK of PICKLED PEPPERS', 'PICK') Returns the position of the set within the string. INSTR('PETER PIPER PICKED a PECK of PICKLED PEPPERS','PI',1,3) INSTR(string, set, ])įinds the location of a set of characters in a string, starting at position start in the string, string, and looking for the first, second, third and so on occurrences of the set. Converts a VARCHAR2 value to a RAW value.Ĭonverts a RAW value to a HEXADECIMAL value.
