I am aware of this usage of the DBMS_SQL.BIND_VARIABLE( I am sorry to say). But, my query was: Could you illustrate possible scenarios in which the ':deptno', ':dname' in
DBMS_SQL.BIND_VARIABLE(cur_hdl,':deptno',deptnum);
DBMS_SQL.BIND_VARIABLE(cur_hdl,':dname', deptname);
are interactively entered. I want to verify whether the following are the main usages of them(?):
SQL> VARIABLE deptno NUMBER (usage scenario 1)
CREATE PACKAGE xxx AS
deptno number;
...
END;
PROCEDURE
...
DBMS_SQL.BIND_VARIABLE(cur_hdl,':xxx.deptno',deptnum);
...
END; (usage scenario 2)
Form Builder "items" (usage scenario 3)
I get this doubt because the concerned variables are declared nowhere, so I have no idea about their sources/potential uses, so that I can apply them when the need arises.
Will you please clarify?
Regards,
Suresh Venkataraman
