Oracle Dynamic SQL

Select value with dynamic SQL

Let's say a user wants to select data from different tables. A table is specified by the user.

FUNCTION get_value(p_table_name VARCHAR2, p_id NUMBER) RETURN VARCHAR2 IS
 EXECUTE IMMEDIATE 'select column_value from ' || p_table_name ||
 ' where id = :P' INTO VALUE USING p_id;

Call this function as usual:

 table_name VARCHAR2(30) := 'my_table';
 id NUMBER := 1;
 DBMS_OUTPUT.put_line(get_value(table_name, id));

Table to test:

CREATE TABLE my_table (id NUMBER, column_value VARCHAR2(100));
INSERT INTO my_table VALUES (1, 'Hello, world!');
