This is the common solution for any table
Run the following Function and fire the follwoing query
CREATE OR REPLACE FUNCTION fnSpecificcol(p_tablename IN
VARCHAR2,
p_columnid IN number,
P_ROWID IN Varchar2)
RETURN VARCHAR2
AUTHID CURRENT_USER AS
TYPE c_refcur IS REF CURSOR;
lc_str VARCHAR2(4000);
out_char varchar2(50);
lc_colval VARCHAR2(4000);
tmp_strSQL varchar2(400);
c_dummy c_refcur;
l number;
BEGIN
tmp_strSQL := 'select column_name from user_tab_cols a '
||
'where upper(table_name)=' || '''' ||
p_tablename || '''' ||
' and column_id=' || p_columnid;
OPEN c_dummy FOR tmp_strSQL;
LOOP
FETCH c_dummy
INTO lc_colval;
EXIT WHEN c_dummy%NOTFOUND;
lc_str := lc_str || lc_colval;
END LOOP;
CLOSE c_dummy;
tmp_strSQL := '';
tmp_strSQL := 'select ' || lc_str || ' from ' ||
p_tablename ||
' A WHERE A.ROWID=' || '''' || P_ROWID
|| '''';
lc_str := '';
lc_colval := '';
OPEN c_dummy FOR tmp_strSQL;
LOOP
FETCH c_dummy
INTO lc_colval;
EXIT WHEN c_dummy%NOTFOUND;
lc_str := lc_str || lc_colval || CHR(13);
END LOOP;
CLOSE c_dummy;
RETURN SUBSTR(lc_str, 1);
EXCEPTION
WHEN OTHERS THEN
lc_str := SQLERRM;
IF c_dummy%ISOPEN THEN
CLOSE c_dummy;
END IF;
RETURN lc_str;
END;
SELECT fnSpecificcol('Tablename', ColumnNumber,A.ROWID)
from Tablename A
eg
SELECT rowtocol('AA', 1,A.ROWID) from aa A
