I'm trying to insert data into table using execute immediate statement. But I get an error
FROM keyword not found where expected
Could anyone take a look what's wrong?
declare
c1 SYS_REFCURSOR;
v_tabl_name varchar2(30);
begin
open c1 for
select tablename from table1;
LOOP
FETCH c1 INTO v_tabl_name;
EXIT WHEN c1%NOTFOUND;
execute immediate 'insert tabl2(tabl_name) (select ''tem'' from'||v_tabl_name||')' ;
END LOOP;
close c1;
end;
create table table1(tem varchar2(50), tablename varchar2(50));
create table tabl2(tabl_name varchar2(50));
insert into table1(tem, tablename) values ('table1','table1');
begin
for rc in (select tablename from table1) loop
--dbms_output.put_line('insert into tabl2(tabl_name) (select ''tem'' from '||rc.tablename||')');
execute immediate 'insert into tabl2(tabl_name) (select ''tem'' from '||rc.tablename||')' ;
end LOOP;
end;

I'm not quite sure what your question is. But I don't understand why you are using a cursor for this. Why not just execute a query like this?
INSERT INTO INFORME_SUBIDA_COMISION (ANIO, EMPLEADO_ID, NOMBRE, APELLIDO, VALOR_COMISION, SUELDO)
SELECT DISTINCT :B_ANIO, E.EMPLEADO_ID, E.NOMBRE, E.APELLIDO,
C.VALOR_COMISION, E.SUELDO
FROM EMPLEADOS E JOIN COMISIONES C
ON C.EMPLEADO_ID = E.EMPLEADO_ID;
Note: I'm guessing what the column names are in INFORME_SUBIDA_COMISION, but you should explicitly list them.
you can use this insert in Bulk Mode if you have huge data to insert
SET SERVEROUTPUT ON
/*use this script to insert data in bulk mode.*/

Hello i use oracle SQL developer
I have create a procedure, and i need to check if a table exist, if not exist i must create how can do?
I have try this
DECLARE v_emp int:=0;
BEGIN
SELECT count(*) into v_emp FROM dba_tables;
if v_emp = 0 then
EXECUTE IMMEDIATE 'create table EMPLOYEE ( ID NUMBER(3), NAME VARCHAR2(30) NOT NULL)';
end if;
END;
but give me an error 00103 because not find table
Just execute the create and watch the exception if thrown. Oracle would never replace the DDL of a table.
declare
error_code NUMBER;
begin
EXECUTE IMMEDIATE 'CREATE TABLE EMPLOYEE(AGE INT)';
exception
when others then
error_code := SQLCODE;
if(error_code = -955)
then
dbms_output.put_line('Table exists already!');
else
dbms_output.put_line('Unknown error : '||SQLERRM);
end if;
end;
You can run this for example:
if (select count(*) from all_tables where table_name = 'yourTable')>0 then
-- table exists
else
-- table doesn't exist
end if;
You should try following,
declare
nCount NUMBER;
v_sql LONG;
begin
SELECT count(*) into nCount FROM dba_tables where table_name = 'EMPLOYEE';
IF(nCount <= 0)
THEN
v_sql:='
create table EMPLOYEE
(
ID NUMBER(3),
NAME VARCHAR2(30) NOT NULL
)';
execute immediate v_sql;
END IF;
end;

You seem confusing cursor and fetched row.
In your current procedure: you open a cursor, do a loop (which looks to be endless since there is no EXIT statement), and after the loop you close the cursor (but it looks it will never happen)
To fetch results from a cursor, do the following:
CREATE OR REPLACE PROCEDURE ...
...
c1 REF_CUR;
ddm_record dims_doc_master%rowtype;
BEGIN
...
OPEN c1;
LOOP
FETCH c1 INTO ddm_record;
EXIT WHEN c1%NOTFOUND;
...
DBMS_OUTPUT.PUT_LINE('Document ID= ' || ddm_record.pyid); -- not c1.pyid
END LOOP;
CLOSE c1;
END;
/
Inspired from examples here: http://plsql-tutorial.com/plsql-explicit-cursors.htm
Try embedding the flag in your where clause:
open c1 FOR
SELECT *
FROM dims_doc_master
WHERE (i_flag='1' AND
(concat_prod_id IS NULL
OR documenttypeid IS NULL
AND (pystatuswork = temp_status))
OR (i_flag<>'1' AND
(documentimageid IS NULL
AND p8id IS NULL)
AND (pystatuswork = temp_status));
The logic can probably be simplified but logically that would work.
I have 2 tables- student and studLoad both having 2 fields studID and studName. I want to load data from student table into stuLoad table.
If the data already exists in the studLoad table, then it should be updated else it should be inserted. following is my code to do so:
create or replace procedure studentLoad is
v_id student.studID%type;
v_name student.studName%type;
v_sn studLoad.studName%type;
cursor cur_load is
select * from student;
begin
open cur_load;
loop
fetch cur_load into v_id,v_name;
exit when cur_load%notfound;
select studName into v_sn from studLoad where studID = v_id;
if(v_sn!= v_name) then
update studLoad set studName= v_name where studID= v_id;
else
insert into studLoad values(v_id,v_name);
dbms_output.put_line(v_id || ' ' || v_name);
end if;
end loop;
close cur_load;
end;
It's not working. the rows in studLoad table are noT updated. How do I solve this? In SQL server we use IF EXISTS(select...from stuLoad..) to check if the record exists in the table, is there a way to do the same in Oracle? if yes then please let me know the same.
This is a highly inefficient way of doing it. You can use the merge statement and then there's no need for cursors, looping or (if you can do without) PL/SQL.
MERGE INTO studLoad l
USING ( SELECT studId, studName FROM student ) s
ON (l.studId = s.studId)
WHEN MATCHED THEN
UPDATE SET l.studName = s.studName
WHERE l.studName != s.studName
WHEN NOT MATCHED THEN
INSERT (l.studID, l.studName)
VALUES (s.studId, s.studName)
Make sure you commit, once completed, in order to be able to see this in the database.
To actually answer your question I would do it something like as follows. This has the benefit of doing most of the work in SQL and only updating based on the rowid, a unique address in the table.
It declares a type, which you place the data within in bulk, 10,000 rows at a time. Then processes these rows individually.
However, as I say this will not be as efficient as merge.
declare
cursor c_data is
select b.rowid as rid, a.studId, a.studName
from student a
left outer join studLoad b
on a.studId = b.studId
and a.studName <> b.studName
;
type t__data is table of c_data%rowtype index by binary_integer;
t_data t__data;
begin
open c_data;
loop
fetch c_data bulk collect into t_data limit 10000;
exit when t_data.count = 0;
for idx in t_data.first .. t_data.last loop
if t_data(idx).rid is null then
insert into studLoad (studId, studName)
values (t_data(idx).studId, t_data(idx).studName);
else
update studLoad
set studName = t_data(idx).studName
where rowid = t_data(idx).rid
;
end if;
end loop;
end loop;
close c_data;
end;
/
If you would like to use your procedure, consider to change some lines:
create or replace procedure studentLoad is
v_id student.studID%type;
v_name student.studName%type;
v_sn studLoad.studName%type;
cursor cur_load is
select * from student;
begin
open cur_load;
loop
fetch cur_load into v_id,v_name;
exit when cur_load%notfound;
begin
select studName into v_sn from studLoad where studID = v_id;
if(v_sn!= v_name) then
update studLoad set studName= v_name where studID= v_id;
end if;
exception
when no_data_found then
insert into studLoad values(v_id,v_name);
end;
dbms_output.put_line(v_id || ' ' || v_name);
end loop;
close cur_load;
end;
I think it should work, didn't test it.
I have a procedure that will select MAX from some tables, but for some reason it is not able to find these tables. Could anybody help me?
declare
varible1 varchar2 (255);
temp varchar2 (255);
last_val number(9,0);
cursor c1 is Select distinct table_name from user_tab_cols order by table_name;
begin
FOR asd in c1
LOOP
temp := asd.table_name;
varible1 := '"'||temp||'"';
select max("id") into last_val from varible1 ;
END LOOP;
end;
For example, the first table name is acceptance_form and for select I need to use "acceptance_form".
Code after edit:
declare
varible1 varchar2 (255);
temp varchar2 (255);
last_val number(9,0);
cursor c1 is Select distinct table_name from user_tab_cols where column_name = 'id';
begin
FOR asd in c1
LOOP
temp := asd.table_name;
execute immediate 'select NVL(max('||'id'||'),0) from "'||varible1||'"' into last_val;
END LOOP;
end;
Can't cuz db is Case sensitive Oracle express 10g tables and rows was created like this
CREATE TABLE "ADMINMME"."acceptance_form"
(
"group_id" NUMBER(9, 0),
"id" NUMBER(4, 0) DEFAULT '0' NOT NULL ,
"is_deleted" NUMBER(4, 0),
"name" NVARCHAR2(30) NOT NULL
);
Can u tell me how to handle exception sequence dosn't exist for this;
Nevermind exception was in wrong block :)
declare
temp varchar2 (255);
last_val number(9,0);
cursor c1 is Select distinct table_name from user_tab_cols where column_name = 'id';
begin
FOR asd in c1
LOOP
temp := asd.table_name;
execute immediate 'select NVL(max("id"),0)+1 from "'||temp||'"' into last_val;
begin
EXECUTE IMMEDIATE 'drop sequence "seq_'|| temp||'"';
EXECUTE IMMEDIATE 'create SEQUENCE "seq_'|| temp ||'" MINVALUE '||last_val||'MAXVALUE 999999999999999999999999999 INCREMENT BY 1 NOCACHE';
EXECUTE IMMEDIATE 'select '||temp||'.nextval from dual';
EXECUTE IMMEDIATE 'ALTER SEQUENCE "seq_'||temp||'" INCREMENT BY 1';
exception when others then
null;
end;
END LOOP;
end;
Dynamic sql doesn't work in that way.
declare
varible1 varchar2 (255);
temp varchar2 (255);
last_val number(9,0);
cursor c1 is Select distinct table_name from user_tab_cols order by table_name;
begin
FOR asd in c1
LOOP
temp := asd.table_name;
begin
execute immediate 'select max(id) from '||temp into last_val;
dbms_output.put_line('max(id) for table: ' ||temp||' = '||last_val);
exception when others then
dbms_output.put_line('Failed to get max(id) for table: ' ||temp);
end;
END LOOP;
end;
You can't use a variable for the table name.
What you can do is creating the complete sql statement as a string and use execute immediate
Here are some examples how to do that: http://docs.oracle.com/cd/B19306_01/appdev.102/b14261/dynamic.htm#CHDGJEGD
