PLSQL query

Question

Oracle version 10.2.0.5
rules_table_temp
rule_id     queue_id     name     value
6     2     PRODUCT     ATM
6     2     CUSTOMER     BR
6     2     STATE     VA
rules_table     
rule_id     queue_id     name     value
4     1     PRODUCT     ATM
4     1     PRODUCT     ABC
4     1     PRODUCT     XYZ
4     1     STATE     AL
4     1     STATE     AZ
5     2     CUSTOMER     APPLE
5     2     CUSTOMER     AT&T
5     2     PRODUCT     ABC
5     2     STATE     VA
For every record in rules_table_temp , I need to check whether this record is already available in rules_table with same name and value. If not, then insert into rules_table else no insert.
For ex:
Name = product, value = ATM - is already available in rules_table .hence skip this record
Name=customer, value=BR – is not available. Hence insert into rules_table
Name =state, value=VA – is already available. Hence skip this record
the output should be as below
rules_table
rule_id     queue_id     name     value
4     1     PRODUCT     ATM
4     1     PRODUCT     ABC
4     1     PRODUCT     XYZ
4     1     STATE     AL
4     1     STATE     AZ
5     2     CUSTOMER     APPLE
5     2     CUSTOMER     AT&T
5     2     PRODUCT     ABC
5     2     STATE     VA
6     2     CUSTOMER     BR
Could you please suggest

Answer 1

your insert statements are not correct
and my query working fine ( just missed a brace at the end)
drop table rules_table;
drop table rules_table_temp;
CREATE TABLE "RULES_TABLE"
( "RULE_ID" NUMBER,
"QUEUE_ID" NUMBER,
"NAME" VARCHAR2(20 BYTE),
"VALUE" VARCHAR2(200 BYTE)
insert into rules_table values(4,1,'PRODUCT','ATM');
insert into rules_table values(4,1,'PRODUCT','ABC');
insert into rules_table values(4,1,'PRODUCT','XYZ');
insert into rules_table values(4,1,'STATE','AL');
insert into rules_table values(4,1,'STATE','AZ');
insert into rules_table values(5,2,'CUSTOMER','APPLE');
insert into rules_table values(5,2,'CUSTOMER','ATT');
insert into rules_table values(5,2,'PRODUCT','ABC');
insert into rules_table values(5,2,'STATE','VA');
create table rules_table_temp as select * from rules_table where 1=2;
insert into rules_table_temp values(6,2,'PRODUCT','ATM');
insert into rules_table_temp values(6,2,'CUSTOMER','BR');
insert into rules_table_temp values(6,2,'STATE','VA');
commit;
insert into rules_table (select * from rules_table_temp r
where not exists ( select * from rules_table where name= r.name and value= r.value));
