Regarding Procedure & Trigger (Plz Some one Help me... Its Urgent)

Question

HI,
I think its a Big Message........ I dont know How many Will have patience in reading this...... Sorry for this Inconvience........
Iam having 4 tables:
3 Input table and 1 target table.
LOgic: Want to Load in the Target table From the input table Based on Some Criteria
Input Tables:
Table 1:Tbl_A
It has ID and Name
TBL_A
Ex: ID Name
201 Anu
202 Banu
203 Chitra
Table 2: Tbl_B
It has Name and Id
(The record of Column Name in this table should Contain the same Names of Tbl_A and id should be different from Table a)
TBl_B:
ID NAME
501 Anu
502 Banu
503 Chitra
Table 3: TBL_C
(It is independent on both Tbl_A and Tbl_b)
it has this Static records as Follows:
TBL_C
ID NAME
1 A
2 P
Output Table:
TBL_Target: ( It has 3 columns): ID,Source id, and Identifier
ID SRC_ID IDENTIFIER
LOgic:
For Loading data into Target tbl :TBL_Target
1. Procedure should have 'Name' of TBL_C as input parameter. So input will be
'A' or 'P'
*Based on the input Name from TBL_C  the corresponding ID should be taken   
from TBL_C and inserted into the ID Column of TBL_Target
EX: IF 'A' Then 1 Should be inserted . IF P means 2 should be inserted
2. we have to select the IDs from TBL_A and TBL_B based on Their Names as Join condition and insert the ID of TBL_A into IDENTIFIER Column of TBL_Target
and insert the ID of TBL_B into SRC_ID Column of TBL_Target
(Note: Actually We have to get the ID'S of all the rows from TBL_A and TBL_B based on their join Condition and load into Target table)
Out PUt: ( if the input of Procedure is 'A')
TBL_Target
ID SRC_ID IDENTIFIER
1 501 201
1 502 202
1 503 203
Out PUt: ( if the input of Procedure is 'P')
TBL_Target
ID SRC_ID IDENTIFIER
2 501 201
2 502 202
2 503 203
LOgic2:
I want to Write a Trigger So that Whenever Iam Inserting New Records in TBL_A
the Trigger should Call the Procedure We have Created
Thanks......

Answer 1

Hi,
I created a Trigger based on After inserting.....
I called the Procedure inside the Trigger.....
Trigger is created. But While executing the trigger it Throws an error: Table is Mutating .Trigger or Function May not see it.
This is the procedure Created:
CREATE OR REPLACE PROCEDURE Proc_Load (Tblc_Name in Varchar2)
AS
-- VARIABLE AND CURSOR DECLARATION:
V_name Varchar2(100);
V_id_c number;
V_id_a number;
V_id_b number;
CURSOR cur_name IS SELECT a.id,b.id
FROM tbl_a a,tbl_b b WHERE TRIM(a.name)=TRIM(b.name);
begin
V_name:=Tblc_name;
SELECT id INTO V_id_c FROM Tbl_c WHERE name=V_name;
OPEN Cur_name;
LOOP
FETCH cur_name INTO V_id_a,V_id_b;
INSERT INTO tbl_target VALUES (V_id_c,V_id_b,V_id_a);
COMMIT;
EXIT WHEN (cur_name %NOTFOUND);
END LOOP;
CLOSE Cur_name;
END;
Trigger Created:
CREATE OR REPLACE TRIGGER Trig_name
AFTER INSERT ON TBL_A
FOR EACH ROW
BEGIN
Proc_Load ('A');
END;
If iam Executing trigger Error OCcurs Table is Mutating .Trigger or Function May not see it.
How to solve it?
