[英]How to Run group of Query with condition SQL Oracle
我正在寫一個 SQL 文件,其中包含不同的部分,如下例所示。 在運行整個文件時,如果輸入值等於部分名稱,它應該運行特定部分:
Def input_var=1;
--//if condition to run 1,2,3 section as per input variable
-------------Section 1-------
--begin
update table1 Set status='RN' where status='IP';
Delete table1 where status='E';
update table2 Set status='RN' where status='IP';
Delete table2 where status='E';
--end
-------------Section 2-------
--begin
update table3 Set status='RN' where status='IP';
Delete table3 where status='E';
update table4 Set status='RN' where status='IP';
Delete table4 where status='E';
--end
..... multiple section
你幾乎沒有選擇。 最簡單的可能是 just if/else it:
BEGIN
IF ( section = 1 )
THEN
Update table1 Set status='RN' where status='IP';
Delete table1 where status='E';
Update table2 Set status='RN' where status='IP';
Delete table2 where status='E';
ELSIF( section = 2 )
THEN
Update table3 Set status='RN' where status='IP';
Delete table3 where status='E';
Update table4 Set status='RN' where status='IP';
Delete table4 where status='E';
ELSIF( section = 3 )
THEN
<code>
ELSE
<code>
END IF;
END;
