The check is: Upgrade Considerations This security regime is stricter than those in Oracle Database 10g, Release 2 (10.2) and previous releases. BIND_ARRAY(c, ':num_array', empno_array); DBMS_SQL.

As a consequence, users of DBMS_SQL may encounter runtime errors on upgrade.

Preventing Inappropriate Use of a Cursor Cursors are protected from security breaches that subvert known existing cursors. Optionally, checks may be performed for every single DBMS_SQL subprogram call. CLOSE_CURSOR(c); EXCEPTION WHEN OTHERS THEN IF DBMS_SQL.

It is the language used to access data stored in a SQL database. For example, a table might have three fields: name, city, and state.With SQL, you can query your database in a variety of ways, using English-like statements. The table will consist of three columns: one for name, one for city, and one for state.Oracle lets you write stored procedures and anonymous PL/SQL blocks that use dynamic SQL. DEFINE_COLUMN(curid, i, numvar); ELSIF desctab(i).col_type = 12 THEN DBMS_SQL. COLUMN_VALUE(curid, i, namevar); ELSIF (desctab(i).col_type = 2) THEN DBMS_SQL. CLOSE_CURSOR(curid); END; / CREATE OR REPLACE PROCEDURE DO_QUERY(mgr_id NUMBER) IS TYPE Cur Type IS REF CURSOR; src_cur Cur Type; curid NUMBER; sql_stmt VARCHAR2(200); ret INTEGER; empnos DBMS_SQL.

Dynamic SQL statements are not embedded in your source program; rather, they are stored in character strings that are input to, or built by, the program at runtime. COLUMN_VALUE(curid, i, numvar); ELSIF (desctab(i).col_type = 12) THEN DBMS_SQL.

colcnt LOOP IF desctab(i).col_type = 2 THEN DBMS_SQL. DEFINE_COLUMN(curid, i, namevar); END IF; END LOOP; -- Fetch Rows WHILE DBMS_SQL. colcnt LOOP IF (desctab(i).col_type = 1) THEN DBMS_SQL.
