    使用print_table单列显示输出,容易阅读.

    create or replace procedure utility.print_table
    ( p_query in varchar2,
    p_date_fmt in varchar2 default ‘dd-mon-yyyy hh24:mi:ss’ )

    — this utility is designed to be installed ONCE in a database and used
    — by all. Also, it is nice to have roles enabled so that queries by
    — DBA’s that use a role to gain access to the DBA_* views still work
    — that is the purpose of AUTHID CURRENT_USER
    AUTHID CURRENT_USER
    is
    l_theCursor integer default dbms_sql.open_cursor;
    l_columnValue varchar2(4000);
    l_status integer;
    l_descTbl dbms_sql.desc_tab;
    l_colCnt number;
    l_cs varchar2(255);
    l_date_fmt varchar2(255);

    — small inline procedure to restore the sessions state
    — we may have modified the cursor sharing and nls date format
    — session variables, this just restores them
    procedure restore
    is
    begin
    if ( upper(l_cs) not in ( ‘FORCE’,’SIMILAR’ ))
    then
    execute immediate
    ‘alter session set cursor_sharing=exact’;
    end if;
    if ( p_date_fmt is not null )
    then
    execute immediate
    ‘alter session set nls_date_format=”’ || l_date_fmt || ””;
    end if;
    dbms_sql.close_cursor(l_theCursor);
    end restore;
    begin
    — I like to see the dates print out with times, by default, the
    — format mask I use includes that. In order to be “friendly”
    — we save the date current sessions date format and then use
    — the one with the date and time. Passing in NULL will cause
    — this routine just to use the current date format
    if ( p_date_fmt is not null )
    then
    select sys_context( ‘userenv’, ‘nls_date_format’ )
    into l_date_fmt
    from dual;

    execute immediate
    ‘alter session set nls_date_format=”’ || p_date_fmt || ””;
    end if;

    — to be bind variable friendly on this ad-hoc queries, we
    — look to see if cursor sharing is already set to FORCE or
    — similar, if not, set it so when we parse — literals
    — are replaced with binds
    if ( dbms_utility.get_parameter_value
    ( ‘cursor_sharing’, l_status, l_cs ) = 1 )
    then

    — parse and describe the query sent to us. we need
    — to know the number of columns and their names.
    dbms_sql.parse( l_theCursor, p_query, dbms_sql.native );
    dbms_sql.describe_columns
    ( l_theCursor, l_colCnt, l_descTbl );

    — are just printing them out
    for i in 1 .. l_colCnt loop
    if ( l_descTbl(i).col_type not in ( 113 ) )
    then
    dbms_sql.define_column
    (l_theCursor, i, l_columnValue, 4000);
    end if;
    end loop;

    — execute the query, so we can fetch
    l_status := dbms_sql.execute(l_theCursor);

    — loop and print out each column on a separate line
    — bear in mind that dbms_output only prints 255 characters/line
    — so we’ll only see the first 200 characters by my design…
    while ( dbms_sql.fetch_rows(l_theCursor) > 0 )
    loop
    for i in 1 .. l_colCnt loop
    if ( l_descTbl(i).col_type not in ( 113 ) )
    then
    dbms_sql.column_value
    ( l_theCursor, i, l_columnValue );
    dbms_output.put_line
    ( rpad( l_descTbl(i).col_name, 30 )
    || ‘: ‘ ||
    substr( l_columnValue, 1, 200 ) );
    end if;
    end loop;
    dbms_output.put_line( ‘—————–‘ );
