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. Using the same key with a different value changes the value.
Does not return information about x Velocity memory optimized columnstore indexes.
If you query sys.dm_db_index_physical_stats on a server instance that is hosting an Always On readable secondary replica, you might encounter a REDO blocking issue.
This is because this dynamic management view acquires an IS lock on the specified user table or view that can block requests by a REDO thread for an X lock on that user table or view.
This unique introductory SQL tutorial not only provides easy-to-understand SQL instructions, but it allows you to practice what you learn using the on-line SQL interpreter.
You will receive immediate results after submitting your SQL commands.
