I have two queries.
Below PL/SQL is not working. I want to store the output into varable test1 and test2. It's saying ORA-00923: FROM keyword not found. Not sure what is wrong
DECLARE
file_id NUMBER(10) NOT NULL :=5;
test1 varchar(100);
test2 varchar(100);
BEGIN
DBMS_OUTPUT.PUT_LINE('File Id: ' || file_id);
SELECT table_name
INTO test1,
(CASE owner
WHEN 'SYS' THEN 'The owner is SYS'
WHEN 'SYSTEM' THEN 'The owner is SYSTEM'
END)
INTO test2
FROM all_tables
WHERE rownum <= 1;
END;
In PL/SQL if i just use the select statement without into clause it's not working. Is it a rule that i need to use into clause. The below one does not work. If i want to spool a output from PL/SQL program do i need to store the output of column into the variable and do a dbms_output?
DECLARE
file_id NUMBER(10) NOT NULL :=5;
test1 varchar(100);
test2 varchar(100);
BEGIN
DBMS_OUTPUT.PUT_LINE('File Id: ' || file_id);
SELECT table_name,
CASE owner
WHEN 'SYS' THEN 'The owner is SYS'
WHEN 'SYSTEM' THEN 'The owner is SYSTEM'
END
FROM all_tables;
END;
You only need one INTO clause in a PL/SQL query, for example:
SELECT table_name, CASE owner WHEN bla bla ... END
INTO test1, test2
FROM all_tables;
