如何在字符串中加入回车换行，tab字符

Posted 2023-04-16

CL_ABAP_CHAR_UTILITIES 中有字符常量:如:CR_LF,HORIZONTAL_TAB,NEWLINE等等.
下面给出字符串中加入回车换行的示例:
DATA: crlf(2) TYPE c.
DATA: l_html(4096) TYPE C.
crlf = cl_ABAP_char_utilities=cr_lf.
CONCATENATE l_html crlf \'_FUNCTION\'\'30\'\'WWW_GET_REPORT\' \'\' INTO l_html.
string的标准函数查找:FIND [FIRST OCCURRENCE|ALL OCCURRENCES OF] pattern IN dobj替换:REPLACE [FIRST OCCURRENCE|ALL OCCURRENCES OF] pattern IN dobj WITH new
REPLACE SECTION [OFFSET off] [LENGTH len] OF dobj WITH new移动:SHIFT c [BY n PLACES] [mode]拼接:CONCATENATE c1 ... cn INTO c [SEPARATED BY s]分割:SPLIT c AT del INTO c1 ... cn.
大小写转换:
TRANSLATE text TO UPPER CASE.
TRANSLATE text TO LOWER CASE.
字符串覆盖:
OVERLAY c1 WITH c2 [ONLY str].
压缩字符串: 参考技术A 字符串中加入回车换行的示例:
DATA: crlf(2) TYPE c.
DATA: l_html(4096) TYPE C.
crlf = cl_ABAP_char_utilities=>cr_lf.
CONCATENATE l_html crlf '_FUNCTION'
'30'
'WWW_GET_REPORT' '>' INTO l_html.

替换: REPLACE [FIRST OCCURRENCE|ALL OCCURRENCES OF] pattern IN dobj WITH new

移动:SHIFT c [BY n PLACES] [mode]
拼接:CONCATENATE c1 ... cn INTO c [SEPARATED BY s]
分割:SPLIT c AT del INTO c1 ... cn.
大小写转换:TRANSLATE text TO UPPER CASE.
TRANSLATE text TO LOWER CASE.
字符串覆盖:OVERLAY c1 WITH c2 [ONLY str].
压缩字符串:CONDENSE c [NO-GAPS].

在sql server 中,如何去掉字符串的头尾回车换行,中间的回车换行不去掉?

1、在sql server 中,如何把回车换行符换成空格？
2、然后，再把空格换成回车换行符？

把回车换行符换成空格 REPLACE(@c,char(13),' ')
把空格换成回车换行符 REPLACE(@c,' ',char(13)) 参考技术A 先将换行符替换空格，然后用trim去掉首尾空格。。。
