in 多个数据使用动态SQL传入字符串
1.动态SQL传入字符串
CREATE OR REPLACE PROCEDURE p_test (v_str VARCHAR2) AS
TYPE cur_type IS REF CURSOR ;
c_fzt cur_type;
v_sql VARCHAR2( 2000);
v_jrh VARCHAR2( 20);
BEGIN
v_sql:=' SELECT jrh FROM fzt_dd WHERE rownum<10 and prod_name IN ('||v_str ||')' ;
OPEN c_fzt FOR v_sql;
LOOP
FETCH c_fzt INTO v_jrh;
EXIT WHEN c_fzt %NOTFOUND ;
dbms_output.put_line (v_jrh );
END LOOP;
END;
BEGIN
p_test( '''普通电话'',''宽带''' );
END;
2.动态SQL传入数字
CREATE OR REPLACE PROCEDURE p_test (v_str VARCHAR2) AS
TYPE cur_type IS REF CURSOR ;
c_fzt cur_type;
v_sql VARCHAR2( 2000);
v_jrh VARCHAR2( 20);
BEGIN
v_sql:=' SELECT jrh FROM fzt_dd WHERE rownum<10 and prod_spec_id IN ('||v_str ||')' ;
OPEN c_fzt FOR v_sql;
LOOP
FETCH c_fzt INTO v_jrh;
EXIT WHEN c_fzt %NOTFOUND ;
dbms_output.put_line (v_jrh );
END LOOP;
END;
BEGIN
p_test( '9,2');
END;
3.动态SQL传入SQL表
CREATE OR REPLACE PROCEDURE p_test (v_str VARCHAR2) AS
TYPE cur_type IS REF CURSOR ;
c_fzt cur_type;
v_sql VARCHAR2( 2000);
v_jrh VARCHAR2( 20);
BEGIN
v_sql:=' SELECT jrh FROM fzt_dd WHERE rownum<10 and prod_spec_id IN ('||v_str ||')' ;
OPEN c_fzt FOR v_sql;
LOOP
FETCH c_fzt INTO v_jrh;
EXIT WHEN c_fzt %NOTFOUND ;
dbms_output.put_line (v_jrh );
END LOOP;
END;
BEGIN
p_test( 'select prod_spec_id from fzt_dd where prod_name=''普通电话''' );
END;
