Oracle - using bind variable in LIKE clause of dynamic cursor

Question

I am using dynamic cursor for fetching data. Query that is being executed looks similar to:

query := \'SELECT column1, column2 
          FROM my_table 
             


        

Answer 1

Take the bind variable out of the string:

VARIABLE mycursor REFCURSOR;
VARIABLE bv1 VARCHAR2;

BEGIN
  :bv1 := 'X'; -- set the bind variable
END;
/

DECLARE
  query VARCHAR2(200) := 'SELECT * FROM DUAL WHERE DUMMY LIKE :value';
BEGIN
  OPEN :mycursor FOR query USING '%' || :bv1 || '%';
END;
/

PRINT mycursor;

Output

MYCURSOR
--------
DUMMY
-----
X
