如何在使用 utl.file wirte plsql 将数据写入 a.csv 文件时处理中文/日文字符

Question

我试图使用以下内容来处理我的数据集中的日语字符，但它似乎不起作用。

UTL_FILE.PUT_LINE(output_file1,chr(9)||CHR(15711167));

任何人都可以提出任何替代方案。

下面是 PL-SQL 代码。

Answer 1

不清楚你在找什么。

CHR(15711167 USING NCHAR_CS)

返回 "뮿" -> U+BBBF: Hangul Syllable Myuh

十进制的EFBBBF是十六进制的 EFBBBF，看起来CHR(... USING NCHAR_CS)忽略了第一个字节，因为它需要偶数个字节。

因此， CHR(48063 USING NCHAR_CS)给出了相同的结果，因为 48063 十进制是BBBF十六进制。

如果您知道 Unicode 代码点，您也可以使用

UTL_I18N.RAW_TO_CHAR(HEXTORAW(TO_CHAR('BBBF', 'fmXXXX')), 'AL16UTF16')

请注意，这仅适用于Basic Multilingual Plane 。 如果您想测试完整的 Unicode 系列，您可以使用这些功能。

-- Similar to Oracle function CHR/NCHR but accept supplementary characters above 65535 (U+FFFF) without transformation to UCS-2
CREATE OR REPLACE FUNCTION CHRF(codepoint INTEGER) RETURN VARCHAR2 DETERMINISTIC IS
    sg1 VARCHAR2(4);
    sg2 VARCHAR2(4);
BEGIN
    IF codepoint <= 65535 THEN
        RETURN UTL_I18N.RAW_TO_CHAR(HEXTORAW(TO_CHAR(codepoint, 'fmXXXX')), 'AL16UTF16');
    ELSE
        sg1 := LPAD(TO_CHAR(TO_NUMBER('D800', 'XXXX') + TRUNC((codepoint - 2**16) / 2**10), 'fmXXXX'), 4, '0');
        sg2 := LPAD(TO_CHAR(TO_NUMBER('DC00', 'XXXX') + (codepoint - 2**16) MOD 2**10, 'fmXXXX'), 4, '0');
        RETURN UTL_I18N.RAW_TO_CHAR(HEXTORAW(sg1||sg2), 'AL16UTF16');
    END IF; 
END CHRF;


-- Similar to Oracle function UNISTR but accept supplementary characters above U+FFFF without transformation to UCS-2.
-- Unlike UNISTR this function supports only one single character
CREATE OR REPLACE FUNCTION UNISTRF(codepoint VARCHAR2) RETURN VARCHAR2 DETERMINISTIC IS
