我有以下代码:
procedure Replace(sUser in Varchar2,sNomTable in varchar2,sColonne in varchar2,sID in Varchar2,nbCharAlterer IN NUMBER) is
l_cursor NUMBER;
l_return NUMBER;
l_ref_cursor SYS_REFCURSOR;
TYPE t_tab IS TABLE OF VARCHAR2(4000);
l_tab t_tab;
l_tab_Id t_tab;
sChaine VARCHAR2(4000 CHAR);
sqlReq CONSTANT VARCHAR2(1000):= 'select ' || sId || ',' || sColonne || ' from ' || sUser || '.' || sNomTable ;
begin
--
l_cursor := DBMS_SQL.open_cursor;
DBMS_SQL.parse(l_cursor, sqlReq, DBMS_SQL.NATIVE);
l_return := DBMS_SQL.EXECUTE(l_cursor);
-- Connvert from DBMS_SQL to a REF CURSOR.
l_ref_cursor := DBMS_SQL.to_refcursor(l_cursor);
这里我收到以下错误:
pls 00302 component 'TO_REFCURSOR' must be declared
因为我的oracle版本是10g。
如何在Oracle 10g中完成等效操作?

以下是如何使用原生动态sql:
PROCEDURE p_replace(suser IN VARCHAR2,
snomtable IN VARCHAR2,
scolonne IN VARCHAR2,
sid IN VARCHAR2,
nbcharalterer IN NUMBER) IS
v_validate_sid_col_name VARCHAR2(32);
v_validate_scolonne_col_name VARCHAR2(32);
v_validate_suser VARCHAR2(32);
v_validate_snomtable VARCHAR2(32);
sqlreq VARCHAR2(2000);
refcur sys_refcur;
BEGIN
-- Check the input values are valid identifiers (to avoid sql injection)
-- N.B. this does not check they are valid object names!
v_validate_sid_col_name := dbms_assert.qualified_sql_name(sid);
v_validate_scolonne_col_name := dbms_assert.qualified_sql_name(scolonne);
v_validate_suser := dbms_assert.qualified_sql_name(suser);
v_validate_snomtable := dbms_assert.qualified_sql_name(scolonne);
sqlReq := 'select ' || v_validate_sid_col_name || ',' ||
v_validate_scolonne_col_name ||
' from ' || v_validate_suser || '.' || v_validate_snomtable;
-- or maybe you want to use execute immediate to bulk collect into arrays?
OPEN refcur FOR sqlreq;
...
END p_replace;
请注意,我已更改过程的名称,因为"替换"是预先存在的内置函数的名称,因此不是一个非常好用的名称。
你没有提到你的查询结果是什么,所以我不确定打开引用光标是你真正需要的,还是批量通过执行立即收集将更好地为您工作。
