I'm trying to create a table and then insert some values in it within the same procedure in pl/sql. I tried to run the following query without success:
create or replace Procedure insertval8(id_no in number,e_name in char)
is
begin
execute immediate 'create table edu2(id number(20), name char(12))';
insert into edu2 values(&id_no,&e_name);
end;
displays
LINE/COL ERROR
-------- -----------------------------------------------------------------
5/1 PL/SQL: SQL Statement ignored
5/13 PL/SQL: ORA-00942: table or view does not exists
The error persists until I remove the insert code.
The procedure cannot be compiled because the table is not present at compile time.
Wrap the insert in execute immediate also, or use a global temporary table (generaly the preferred solution for temporary data).
create or replace procedure insertval8 (id in number,
name in char )
is
begin
execute immediate 'create table edu2(id number(20), name char(12))';
execute immediate 'insert into edu2(id, name) values (:1, :2)'
using id, name;
end;

My stored procedure is like this:
create or replace procedure tpk.sp_Test_proc
IS
err_code NUMBER;
err_msg VARCHAR (500);
v_tbl_cnt NUMBER;
v_tbl_valid NUMBER;
Begin
SELECT COUNT(*) INTO v_tbl_cnt FROM USER_TABLES
WHERE TABLE_NAME IN (UPPER('Tbl1'),UPPER('tbl2'),UPPER('tbl3'));
IF(v_tbl_cnt =3) THEN
EXECUTE IMMEDIATE 'TRUNCATE TABLE Tbl1';
EXECUTE IMMEDIATE 'TRUNCATE TABLE Tbl2';
EXECUTE IMMEDIATE 'TRUNCATE TABLE Tbl3';
EXECUTE IMMEDIATE 'DROP TABLE Tbl1';
EXECUTE IMMEDIATE 'DROP TABLE Tbl2';
EXECUTE IMMEDIATE 'DROP TABLE Tbl3';
EXECUTE IMMEDIATE
'CREATE global temporary TABLE tbl1
( Id Integer... )'
Insert into tbl1
Select * from another_schema.Dw_table /* In this line it throws error Table does not exist */
end if;
end;
I tired same table with store procedure only to fetch the data its working there but when I used in Insert statement it throws an error
PL/SQL: ORA-00942 table or view does not exist.
I am totally confused - what's wrong here?
Select * from another_schema.Dw_table
You don't have a privilege to select from that table. Even if you think you do (granted via a role), it won't work in stored procedures - you have to grant it directly to user you're connected to.
Besides, there's no point in truncating tables first, and dropping them next. Just drop them.
Furthermore, there's rarely need to create tables dynamically (the way you do it), especially global temporary tables. Create them once, use them many times. No dropping. No (re)creating them in PL/SQL.
I have the following code in PLSQL:
Declare
tablename varchar2(20):='emp';
drop_stmt varchar2(2000);
begin
drop_stmt:='drop table :1 ;';
--dbms_output.put_line(drop_stmt);
execute immediate drop_stmt using tablename;
end;
Results in:
ORA-00903:invalid table name
ORA-06512: at line 8
However when I run:
drop table emp ;
it just successfully runs. What may be the cause of this error?
You must use this one:
drop_stmt:='drop table '||tablename; -- without ";" at the end of string
--dbms_output.put_line(drop_stmt);
execute immediate drop_stmt;
I am trying to write a stored procedure that selects indiv_ids and transaction_ids and inserts these into a table on my schema. In doing so, I want to pass in variables and have the stored procedure use if statements to select the indiv_ids and transaction_ids from different tables depending on the information passed in. I've tried a few variations and can't get the procedure to work without an error. Thanks!
create or replace procedure myproc (name_type in varchar2, dept in number)
is begin
if name_type='promo' then insert into mytable(indiv_id,transaction_id)
---sql here;
commit;
elsif name_type='deal' then insert into mytable(indiv_id, transaction_id)
---sql here;
commit;
end if;
end;
errors: Error(8,10): PL/SQL: SQL Statement ignored,
Error(16,31): PL/SQL: ORA-00942: table or view does not exist
Note that name_type variable is declared as NUMBER, but in the procedure body it is compared with strings:
if name_type='promo' then
This is not the cause of ORA-00942 error, but anyway it makes your procedure not working correctly.
I am a SQL Server user and I have a small project to do using Oracle, so I’m trying to understand some of the particularities of Oracle and I reckon that I need some help to better understand the following situation:
I want to test if a temporary table exists before creating it so I had this code here:
DECLARE
table_count INTEGER;
var_sql VARCHAR2(1000) := 'create GLOBAL TEMPORARY table TEST (
hello varchar(1000) NOT NULL)';
BEGIN
SELECT COUNT(*) INTO table_count FROM all_tables WHERE table_name = 'TEST';
IF table_count = 0 THEN
EXECUTE IMMEDIATE var_sql;
END IF;
END;
It works normally, so after I executed it once, I added an else statement on my IF:
ELSE
insert into test (hello) values ('hi');
Executed it again and a line was added to my test table.
Ok, my code was ready and working, so I dropped the temp table and tried to run the entire statement again, however when I do that I get the following error:
ORA-06550: line 11, column 19:
PL/SQL: ORA-00942: table or view does not exist
ORA-06550: line 11, column 7:
PL/SQL: SQL Statement ignored
06550. 00000 - "line %s, column %s:\n%s"
*Cause: Usually a PL/SQL compilation error.
*Action:
Then I changed my else statement to this and now it works again:
ELSE
EXECUTE IMMEDIATE 'insert into test (hello) values (''hi'')';
My question is why running individually I can simply use the insert instead of the EXECUTE IMMEDIATE and also why my SELECT statement right after BEGIN still works when all the rest appears to need EXECUTE IMMEDIATE to run properly?
The whole PL/SQL block is parsed at compile time, but the text within a dynamic statement isn't evaluated until runtime. (They're close to the same thing for an anonymous block, but still distinct steps).
Your if/else isn't evaluated until runtime either. The compiler doesn't know that the table will always exist by the time you do your insert, it can only check whether or not it exists at the point it parses the whole block.
If the table does already exist then it's OK; the compiler can see it, the block executes, your select gets 1, and you go into the else to do the insert. But if it does not exist then the parsing of the insert correctly fails with ORA-00942 at compile time and nothing in the block is executed.
Since the table creation is dynamic, all references to the table have to be dynamic too - your insert as you've seen, but also if you then query it. Basically it makes your code much harder to read and can hide syntax errors - since the dynamic code isn't parsed until run-time, and it's possible you could have a mistake in a dynamic statement in a branch that isn't hit for a long time.
Global temporary tables should not be created on-the-fly anyway. They are permanent objects with temporary data, specific to each session, and should not be created/dropped as part of your application code. (No schema changes should be made by your application generally; they should be confined to upgrade/maintenance changes and be controlled, to avoid errors, data loss and unexpected side effects; GTTs are no different).
Unlike temporary tables in some other relational databases, when you create a temporary table in an Oracle database, you create a static table definition. The temporary table is a persistent object described in the data dictionary, but appears empty until your session inserts data into the table. You create a temporary table for the database itself, not for every PL/SQL stored procedure.
Create the GTT once and make all your PL/SQL code static. If you want something closer to SQL Server's local temporary tables then look into PL/SQL collections.
PL/SQL: ORA-00942: table or view does not exist
It is compile time error, i.e. when the static SQL is parsed before even the GTT is created.
Let's see the difference between compile time and run time error:
Static SQL:
SQL> DECLARE
2 v number;
3 BEGIN
4 select empno into v from a;
5 end;
6 /
select empno into v from a;
*
ERROR at line 4:
ORA-06550: line 4, column 26:
PL/SQL: ORA-00942: table or view does not exist
ORA-06550: line 4, column 1:
PL/SQL: SQL Statement ignored
Dynamic SQL:
SQL> DECLARE
2 v number;
3 BEGIN
4 execute immediate 'select empno from a' into v;
5 end;
6 /
DECLARE
*
ERROR at line 1:
ORA-00942: table or view does not exist
ORA-06512: at line 4
In the 1st PL/SQL block, there was a semantic check at compile time, and you could see the PL/SQL: ORA-00942: table or view does not exist. In the 2nd PL/SQL block, you do not see the PL/SQL error.
Bottomline,
At compile time it is not known if the table exists, as it is
only created at run time.
In your case, to avoid this behaviour, you need to make the INSERT also dynamic and use EXECUTE IMMEDIATE. In that way, you can escape the compile time error and get the table created dynamically and also do an insert into it dynamically at run time.
Having said that, the basic problem is that you are trying to create GTT on the fly which is not a good idea. You should create it once, and use it the way you want.
I have modified your code a litle bit and it works as far as logic is concerned. But as exp[lained in earlier posts creating GTT on the fly at run time is not at all is a goood idea.
--- Firstly by dropping the table i.e NO TABLE EXISTS in the DB in AVROY
SET serveroutput ON;
DECLARE
table_count INTEGER;
var_sql VARCHAR2(1000) := 'create GLOBAL TEMPORARY table TEST (
hello varchar(1000) NOT NULL)';
BEGIN

SELECT COUNT(*)
INTO table_count
FROM all_tables
WHERE table_name = 'TEST'
AND OWNER = 'AVROY';
IF table_count = 0 THEN
EXECUTE IMMEDIATE var_sql;
dbms_output.put_line('table created');
ELSE

I executed a PL/SQL script that created the following table
TABLE_NAME VARCHAR2(30) := 'B2BOWNER.SSC_Page_Map';
I made an insert function for this table using arguments
CREATE OR REPLACE FUNCTION F_SSC_Page_Map_Insert(
p_page_id IN B2BOWNER.SSC_Page_Map.Page_ID_NBR%TYPE,
p_page_type IN B2BOWNER.SSC_Page_Map.Page_Type%TYPE,
p_page_dcpn IN B2BOWNER.SSC_Page_Map.Page_Dcpn%TYPE)
I was notified I had to declare B2BOWNER.SSC_Page_Map prior to it appearing as an argument to my function. Why am I getting this error?

So I finally conducted an insert into the table via the schema using PL/SQL and it worked fine. It appears I simply do not have authority to create functions but that is an assumption.

When creating the TABLE under B2BOWNER, be sure to prefix the PL/SQL function with the Schema name; i.e. B2BOWNER.F_SSC_Page_Map_Insert.
I did not realize this until the DBAs pointed it out. I could have created the table under my root USER/SCHEMA and the PL/SQL function would have worked fine.
The procedure name should be in caps while creating procedure in database.
You may use small letters for your procedure name while calling from Java class like:
String getDBUSERByUserIdSql = "{call getDBUSERByUserId(?,?,?,?)}";
In database the name of procedure should be:
GETDBUSERBYUSERID -- (all letters in caps only)
This serves as one of the solutions for this problem.
you should give permission on your db
grant execute on (packageName or tableName) to user;
