我正在尝试让 SQL*Plus 在其输出文件中写入进度，该文件应该可以作为报告呈现，即没有应用程序原生的不良格式。特别是，我想摆脱每行似乎都以 SQL> 开头的 SQL>。这是我调用 sqlplus 的 shell 脚本：
#!/usr/bin/ksh
$ORABIN/sqlplus $ORADBUSER/$ORADBPASSWD@$ORADB<<!!>./orclTest.log
SELECT 'IN sqlplus' AS MESSAGE1 FROM dual;
VARIABLE rowCnt number;
BEGIN
SELECT COUNT(*) INTO :rowCnt FROM dual;
END;
/
SELECT 'Dual has ' || :rowCnt || ' rows' AS MESSAGE2 FROM dual;
!!
当我运行它时，这是我在 orclTest.log 中得到的：

SQL> SQL>
MESSAGE1
----------
IN sqlplus
SQL> SQL> SQL> SQL> 2 3 4
PL/SQL procedure successfully completed.
SQL> SQL>
MESSAGE2
------------------------------------------------------
Dual has 1 rows
告诉 sqlplus 不要给我它的标准格式的任何方法，比如标题和前缀，并且只输出：
MESSAGE1
----------
IN sqlplus
MESSAGE2
------------------------------------------------------
Dual has 1 rows
