oracle中split是關(guān)鍵字？

【專家解說】：oracle 中的split是分區(qū)里有數(shù)據(jù)檢索用的,具體也不知道怎用, 不是JAVA里的split函數(shù), 若想要在oracle 實(shí)現(xiàn)些函數(shù) CREATE OR REPLACE TYPE ty_str_split IS TABLE OF VARCHAR2 (4000); CREATE OR REPLACE FUNCTION fn_split (p_str IN VARCHAR2, p_delimiter IN VARCHAR2) RETURN ty_str_split IS j INT := 0; i INT := 1; len INT := 0; len1 INT := 0; str VARCHAR2 (4000); str_split ty_str_split := ty_str_split (); BEGIN len := LENGTH (p_str); len1 := LENGTH (p_delimiter); WHILE j < len LOOP j := INSTR (p_str, p_delimiter, i); IF j = 0 THEN j := len; str := SUBSTR (p_str, i); str_split.EXTEND; str_split (str_split.COUNT) := str; IF i >= len THEN EXIT; END IF; ELSE str := SUBSTR (p_str, i, j - i); i := j + len1; str_split.EXTEND; str_split (str_split.COUNT) := str; END IF; END LOOP; RETURN str_split; END fn_split; / 測(cè)試： DECLARE CURSOR c IS SELECT * FROM TABLE (CAST (fn_split ('1;;12;;123;;1234;;12345', ';;') AS ty_str_split ) ); r c%ROWTYPE; BEGIN OPEN c; LOOP FETCH c INTO r; EXIT WHEN c%NOTFOUND; DBMS_OUTPUT.put_line (r.column_value); END LOOP; CLOSE c; END; / 結(jié)果： 1 12 123 1234 12345
