问题描述
您好,
我正在写一个shell脚本,它处理DB(Oracle)表操作(创建,更新,更改,插入等...)
对于每个操作我都写了单独的shell脚本函数。
请告诉我,有必要在下面的每一个函数中连接到oracle吗?
sqlplus -s scott / tiger<< EOF
请告诉我这个数据库连接的范围是函数还是整个脚本?
我用这个语句编写了一个DB_Connection函数,其他函数从脚本中的main函数调用。
主函数包括DB_connection,Create_Table,inser_rows等...函数。
因此,在编写任何DDL语句之前,必须在每个函数中写入此行。
Eg
sqlplus -s scott / tiger<< EOF
选择*从< table_name>
退出
EOF
提前致谢。 :-O
Hello,
I am writting a shell script, which handles DB(Oracle) table operations (create, update, alter, insert etc...)
For each operation I had written seperate shell script function.
Could you please tell me that, it is necessary to connect to oracle in every function with below line?
sqlplus -s scott/tiger << EOF
Please tell me the scope of this DB connection is functionwise or its overall to the script?
I had written a DB_Connection function with this statement and other functions are getting called from main function in script.
Main function includes DB_connection, Create_Table, inser_rows etc...functions.
So is it necessary to write this line in every function before writting any DDL statement.
E.g.
sqlplus -s scott/tiger << EOF
Select * from <table_name>
exit
EOF
Thanks in advance. :-O
