Question

我使用shell脚本在sqlplus中执行导出

阀芯：

SET echo off
SET linesize 32767
SET LONG 1000
SET LONGCHUNKSIZE 1000
SET wrap off
SET heading off
SET colsep ';'
SET pagesize 0
SET feed off
SET termout off
SET trimspool off

SELECT
AUTO_SEQ.nextval as ROW_ID,
..
..

结果：

  29419987;FOR_IMPORT;1000         ;KR 19 F 65 73                                                                                                                                                                       ;KR 19 F 65 73, 47001, 47000                                                                                                                                                                                                                         ;SANTA MARTA                                                                                                                                                                                                                                                                                                                                                             ;Cargado por EIM en 03-MAY-17         ;KR 19 F 65 73, 47001, 47000                                                                                             ;KR 19 F 65 73, 47001, 47000                                                                                             ;KR 19 F 65 73, 47001, 47000                                                                                             ;MAGDALENA                                                                                                                                                                                                                                                                                                                                                               ;          ;COLOMBIA;                                                            ;                                                            ;                                                                                          ;   ;         ;Y;N;Y

结果在数据之前和/或之后有很多空白，所以我的问题是如何删除它们？

提前致谢。

Answer 2

设置colsep不会停止在列中输出结果，这意味着每行中的值仍然填充到相同的长度。我会忘记colsep，而是将值与分隔符连接起来：

SELECT
  AUTO_SEQ.nextval
  ||';'|| column1
  ||';'|| column2
  ...
  ||';'|| columnN
FROM
  ...

它提供单个列表达式，没有添加额外的空格。

你可能需要将字符串值sin双引号括起来，如果它们本身可以包含分隔符（虽然这在某种程度上取决于谁将使用它），并且你也可以将它们连接起来。您还应该明确地将日期格式化为字符串等，如果您还没有。
