How to use Pro*C

Question

HI!
I have a problem with using Pro*c.
I have to store values in a database.
I am able to do that with fixes numbers, but not with values.
My code is:
EXEC SQL EXECUTE
BEGIN
INSERT INTO XML (art_id,titel,fachgebiet,arttext) values (1,'der Titel',' Imunologie ','Das ist der Text2');
END;
END-EXEC;
How can I store varying values in a database?
Please help me.
Thank you

Answer 1

In the basic C code you to declare variable that needs to be passed to oracle with in
EXEC SQL BEGIN DECLARE SECTION
VARCHAR empname[11];
VARCHAR jobtype[9];
VARCHAR hired[9];
int salary;
int dept;
int worked_longer;
int higher_sal;
int total_in_dept;
VARCHAR uid[20];
VARCHAR pwd[20];
EXEC SQL END DECLARE SECTION;
The datatype supported are basic C datatypes and varchar etc.
Then you can assign values to these variables in your C code and can reference these variable in a PL/SQL block prefixed by : , this are called host variables .
Then your code will look like
EXEC SQL EXECUTE
BEGIN
INSERT INTO XML (art_id,titel,fachgebiet,arttext) values (:art_id,:title,:fachgebiet ,:arttext );
END;
END-EXEC;
Hope i have answered your question .
