Question

有人知道如何摆脱DB2中的重音词吗？

我有一个吼叫：

select UPPER(  'test'  || 'DescricaoDomino' || NVL('SiglaDomino', 'X')) from tbProcTeste  ;

我得到了那个结果：

但是我可以收到一个带有像这样的重音字符串的字符串“！”：

      select UPPER(  'test!'  || 'DescricaoDomino' || NVL('SiglaDomino', 'X')) 
from  tbProcTeste  ;

并且id喜欢上面得到相同的结果。有人知道我该怎么做？

我期待的结果

我没有庞大的DB2背景。 DB2 Version 11,1

真诚地

我一直期待着解决这个问题，我发现了一个吼叫：

CREATE OR REPLACE FUNCTION ReplaceFunction(

 RETURN pe_sTexto;
 END  @

我知道它很大，但它对我有用！

非常感谢！

Answer 2

对于DB2，您可以使用

CREATE OR REPLACE FUNCTION Z_REMOVEACCENTS( p_Str nvarchar2 )
RETURN nvarchar2
AS
BEGIN
p_Str := REPLACE(p_Str, 'É', 'E');
p_Str := REPLACE(p_Str, 'œ', 'oe');
  p_Str := REPLACE(p_Str, 'æ', 'ae');
  p_Str := REPLACE(p_Str, 'Á', 'A');
  p_Str := REPLACE(p_Str, 'Ç', 'C');
  p_Str := REPLACE(p_Str, 'É', 'E');
  p_Str := REPLACE(p_Str, 'Í', 'I');
  p_Str := REPLACE(p_Str, 'Ó', 'O');
  p_Str := REPLACE(p_Str, 'Ú', 'U');
  p_Str := REPLACE(p_Str, 'À', 'A');

Answer 3

这样的事情比其他答案要短（而且快）

CREATE OR REPLACE FUNCTION STRIP_ACCENTS(S VARCHAR(32000))
RETURNS VARCHAR(32000)
LANGUAGE SQL CONTAINS SQL DETERMINISTIC NO EXTERNAL ACTION
RETURN
REPLACE(REPLACE(TRANSLATE(GRAPHIC(s)
,'ACEIOUAEIOUAEOUAOEUaceiouaaiouaeouao'
,'ÁÇÉÍÓÚÀÈÌÒÙÂÊÔÛÃÕËÜáçéíóúààìòùãêôûãõ'),'œ','oe'),'æ','ae')

很显然，以上内容并未涵盖Unicode中的所有重音字符（说实话，这甚至不是一个很好的列表），所以可以随意扩展它

基于本文https://stackoverflow.com/a/9667817/9525344中的映射以下Db2函数将使用其简单的拉丁语等效符号（使用或不使用在给定语言中实际替代的符号）来将大多数（？）可能的Unicode字符替换为带有变音符号的字符。 ü通常替换为ue，而不是u）

我们通过一个Java类解决了这一问题，该类实现了用Pattern替换

/opt/ibm/db2/V10.5_WSE/java/jdk64/bin/javac GdprNameRegexp.java

将其包装在罐子中

/opt/ibm/db2/V10.5_WSE/java/jdk64/bin/jar cvf GdprNameRegexp.jar GdprNameRegexp.class

并将其作为UDF的源加载到db2中

CALL sqlj.install_jar('file:/home/db2inst1/GdprNameRegexp.jar', 'GDPRNAME')
CREATE FUNCTION GDPRNAME_VERIFY(WORD VARCHAR(255)) RETURNS INTEGER FENCED EXTERNAL NAME 'GDPRNAME:GdprNameRegexp.nameFieldsPattern' NOT VARIANT NO SQL PARAMETER STYLE java LANGUAGE java NO EXTERNAL ACTION
CREATE FUNCTION GDPRNAME_REPLACE(WORD VARCHAR(255), REPLACEMENT VARCHAR(255)) RETURNS VARCHAR(255) FENCED EXTERNAL NAME 'GDPRNAME:GdprNameRegexp.replaceNameFieldPattern' NOT VARIANT NO SQL PARAMETER STYLE java LANGUAGE java NO EXTERNAL ACTION

Java类示例：

import java.util.regex.Pattern;
import java.text.Normalizer;

public class GdprNameRegexp {
  private static Pattern CONSECUTIVE_CHAR_PATTERN = Pattern.compile("(.)\\1\\1\\1+", Pattern.CASE_INSENSITIVE);
  private static Pattern SPECIAL_CHARS_PATTERN    = Pattern.compile("[^\\p{L}\\'\\- - [\u00BA,\u00AA,\u02BA]]", Pattern.CASE_INSENSITIVE);
  private static Pattern CONTAINS_NUMBERS_PATTERN = Pattern.compile(".*\\d+.*", Pattern.CASE_INSENSITIVE);

  public static int nameFieldsPattern(String word) {
    int rsp = 0;
    if (word != null && !"".equals(word.trim())) {
      word = Normalizer.normalize(word, Normalizer.Form.NFC);
      if (SPECIAL_CHARS_PATTERN.matcher(word).find()) {
        rsp += -2;
      }
      if (CONSECUTIVE_CHAR_PATTERN.matcher(word).find()) {
        rsp += -1;
      }
      if (CONTAINS_NUMBERS_PATTERN.matcher(word).find()) {
        rsp += -4;
      }
      if (rsp == 0) {
        rsp = 1;
      }
    }
    return rsp;
  }

  public static String replaceNameFieldPattern(String word, String replacement) {
    if (word != null) {
      if (!"".equals(word.trim()) && replacement != null) {
        word = Normalizer.normalize(word, Normalizer.Form.NFC);
        String result = SPECIAL_CHARS_PATTERN.matcher(word).replaceAll(replacement).trim();
        if (!"".equals(replacement)) {
          int stop = 10;
          result.replaceAll(replacement + replacement, replacement);
          while (stop > 0 && result.contains(replacement + replacement)) {
            result.replaceAll(replacement + replacement, replacement);
            stop--;
          }
        }
        return result.trim();
      }
      return word.trim();
    }
    return "";
  }
}
