OPEN SQL去掉文本中间的空格

使用OPEN SQL的函数： replace_regexpr

|--------------------------------------------------------------------------------------------------------------------------------------------------------|
| REPLACE_REGEXPR( pcre = pcre, value = sql_exp1, with = sql_exp2* $* , occurrence = occ*$ * $* , case_sensitive = case*$ $* , start = start*$ ) |

|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| A Perl Compatible Regular Expression (PCRE) pcre is replaced in sql_exp1 with the character string specified in sql_exp2. occ is optional and determines the number of occurrences of pcre to be replaced. By default, all occurrences are replaced. The search is case-sensitive by default, but this can be overridden using the parameter case. The parameter start specifies the offset from which to start the search. 在 sql_exp1 中搜索符合 PCRE 正则表达式 的内容，并将其替换为 sql_exp2 指定的字符串。 * occ (occurrence)：可选参数。指定替换第几次出现的匹配项。默认替换全部。 * case (case_sensitive)：默认区分大小写，可通过此参数修改。 * start：指定从哪个字符位置（偏移量）开始搜索。 |

DATA lv_empty TYPE char1.

SELECT matnr,maktx,
  replace_regexpr( pcre = '\s+',value = maktx, with = @lv_empty ) AS nospace_maktx
  FROM makt
 WHERE matnr = 'RB0009000046'
   AND spras = @sy-langu
  INTO TABLE @DATA(lt_out).

正则表达式	含义	处理方式
`\s`	匹配单个空白字符	发现 1 个空格，执行 1 次替换。
`\s+`	匹配一个或多个连续的空白字符	发现连续的 N 个空格，把它们看作一个整体，只执行 1 次替换。
