如何将参数传递给 sqlplus 中使用 START 调用的 sql 文件中的 PL/SQL 块?
我有一个通过 sqlplus 运行多个 sql 文件的 bash 脚本:
I have a bash script running several sql files via sqlplus:
sqlplus $connectioninfo << end
start file1.sql
start file2.sql
start file3.sql $variable
quit
end
file3 有一些 PL/SQL:
file3 has some PL/SQL:
BEGIN
DBMS_OUTPUT.PUT_LINE(&1);
END;
/
但它只是打印文字 "&1" 而不是 $variable 的值.我也在 file3 中尝试了以下内容:
But it just prints the literal "&1" instead of the value of $variable. I have also tried the following in file3:
DEFINE var_a = &1;
BEGIN
DBMS_OUTPUT.PUT_LINE(var_a);
END;
/
还有以下内容:
DECLARE
var_b VARCHAR2(64) := &1;
BEGIN
DBMS_OUTPUT.PUT_LINE(var_b);
END;
/
最后:
DEFINE var_a = &1;
DECLARE
var_b VARCHAR2(64) := var_a;
BEGIN
DBMS_OUTPUT.PUT_LINE(var_b);
END;
/
但是，我收到了各种错误，或者只是所有这些错误的字面值&1".
However, I am getting various errors or just the literal value '&1' for all of these.
推荐答案
尝试将 SET DEFINE ON 添加到脚本的开头 file3.sql.
Try adding SET DEFINE ON to the start of your script file3.sql.
如果SET DEFINE 是ON，SQL*Plus 将用它们的值替换&... 替换参数.如果 SET DEFINE 是 OFF(它似乎适合您)，SQL*Plus 不会这样做.
If SET DEFINE is ON, SQL*Plus will replace &... substitution parameters with their values. If SET DEFINE is OFF (which it seems to be for you), SQL*Plus won't do this.
