Updating into string function mssql

This means that for a string containing five two-byte characters, LENGTH() returns 10, whereas CHAR_LENGTH() returns 5.

SELECT CHAR_LENGTH("text"); --------------------------------------------------------- | CHAR_LENGTH("text") | --------------------------------------------------------- | 4 | --------------------------------------------------------- 1 row in set (0.00 sec) CHARACTER_LENGTH() is a synonym for CHAR_LENGTH().

SELECT HEX(255); --------------------------------------------------------- | HEX(255) | --------------------------------------------------------- | FF | --------------------------------------------------------- 1 row in set (0.00 sec) SQL SELECT 0x616263; --------------------------------------------------------- | 0x616263 | --------------------------------------------------------- | abc | --------------------------------------------------------- 1 row in set (0.00 sec) Returns the string str, with the substring beginning at position pos and len characters long replaced by the string newstr.

Returns the original string if pos is not within the length of the string.

Today, one of the developers come to me and asked me the question that is there any T-SQL function that he could use to remove everything before and after a specific character in string.

The second syntax returns the position of the first occurrence of substring substr in string str, starting at position pos. SELECT LOCATE('bar', 'foobarbar'); --------------------------------------------------------- | LOCATE('bar', 'foobarbar') | --------------------------------------------------------- | 4 | --------------------------------------------------------- 1 row in set (0.00 sec) SELECT LOWER('QUADRATICALLY'); --------------------------------------------------------- | LOWER('QUADRATICALLY') | --------------------------------------------------------- | quadratically | --------------------------------------------------------- 1 row in set (0.00 sec) SELECT LPAD('hi',4,'??Replaces the rest of the string from position pos if len is not within the length of the rest of the string. SELECT INSERT('Quadratic', 3, 4, 'What'); --------------------------------------------------------- | INSERT('Quadratic', 3, 4, 'What') | --------------------------------------------------------- | Qu Whattic | --------------------------------------------------------- 1 row in set (0.00 sec) SELECT INSTR('foobarbar', 'bar'); --------------------------------------------------------- | INSTR('foobarbar', 'bar') | --------------------------------------------------------- | 4 | --------------------------------------------------------- 1 row in set (0.00 sec) SELECT LEFT('foobarbar', 5); --------------------------------------------------------- | LEFT('foobarbar', 5) | --------------------------------------------------------- | fooba | --------------------------------------------------------- 1 row in set (0.00 sec) Returns the length of the string str, measured in bytes. This means that for a string containing five two-byte characters, LENGTH() returns 10, whereas CHAR_LENGTH() returns 5.SELECT LENGTH('text'); --------------------------------------------------------- | LENGTH('text') | --------------------------------------------------------- | 4 | --------------------------------------------------------- 1 row in set (0.00 sec) Reads the file and returns the file contents as a string.str1 corresponds to bit 0, str2 to bit 1, and so on. Returns a string representation of the octal value of N, where N is a longlong (BIGINT) number. If the leftmost character of the string str is a multi-byte character, returns the code for that character, calculated from the numeric values of its constituent bytes using this formula − SELECT ORD('2'); --------------------------------------------------------- | ORD('2') | --------------------------------------------------------- | 50 | --------------------------------------------------------- 1 row in set (0.00 sec) POSITION(substr IN str) is a synonym for LOCATE(substr,str).Quotes a string to produce a result that can be used as a properly escaped data value in an SQL statement.
