varchar2(2000) 为什么内容长度只有1056多，剩余的就显示不了呢，实际内容2100
使用语句：
- SQL code
DECLARE SQLSTR VARCHAR2(4000); V_DAYS VARCHAR2(2);BEGIN FOR I IN 1 .. 31 LOOP IF I < 10 THEN V_DAYS := '0' || I; ELSE V_DAYS := I; END IF; -- V_COUNT := V_COUNT + 1; IF I < 16 THEN SQLSTR := SQLSTR || ',max(case SUBJECT when ''D07' || V_DAYS || ''' then COUNTI else 0 end) as ''D07' || V_DAYS || '''' || CHR(10); END IF; END LOOP; DBMS_OUTPUT.PUT_LINE(SQLSTR); DBMS_OUTPUT.PUT_LINE(LENGTHB(SQLSTR));END;
显示文本：“,max(case SUBJECT when 'D0716' then COUNTI else 0 end) as 'D0716'
,max(case SUBJECT when 'D0717' then COUNTI else 0 end) as 'D0717'
