I am trying to execute a procedure which in turn should execute four other procedures one after the other. How do I acheive this?
Create or replace procedure mainproc
as
begin
tack(400);
phno_insert;
address_insert;
academics_insert;
commit;
end;
Error report:
PLS-00905: Object phno_insert is invalid. PL/SQL: Statement ignored.
PLS-00905: Object address_insert is invalid. PL/SQL: Statement
ignored. PLS-00905: Object academics_insert is invalid. PL/SQL:
Statement ignored.
The problem seems to be in the fact that you have a procedure doing a DDL over an object that is statically referenced in another procedure; for example, if I define:
create table runtimeTable as select 1 as one from dual;
create or replace procedure createTable is
begin
execute immediate 'drop table runtimeTable';
execute immediate 'create table runtimeTable as select 1 as one from dual';
end;
create or replace procedure useTable is
vVar number;
begin
select one
into vVar
from runtimeTable;
--
dbms_output.put_line(vVar);
end;
create or replace procedure createAndUseTable is
begin
createTable;
useTable;
end;
/
when I try to execute createAndUseTable I get:
ORA-04068: existing state of packages has been discarded ORA-04065:
not executed, altered or dropped stored procedure "ALEK.USETABLE"
ORA-06508: PL/SQL: could not find program unit being called:
"ALEK.USETABLE" ORA-06512: at "ALEK.CREATEANDUSETABLE", line 4
ORA-06512: at line 1
If you strictly need to do a DDL runtime, you need to use dynamic SQL to reference the modified object; for example if I define the procedure useTable this way
create or replace procedure useTable is
vVar number;
begin
execute immediate
'select one
from runtimeTable'
into vVar;
--
dbms_output.put_line(vVar);
end;
the call to createAndUseTable will work:
SQL> exec createAndUseTable

I'm writing a PL/SQL program, I've created a procedure and the syntax is correct.
Running this on DataGrip.
`
declare
create or replace procedure salutation(x OUT number) is begin
x:= x*10;
end salutation;
begin
SYS.DBMS_OUTPUT.PUT_LINE('hello');
end;
`
I get error messages when I execute the code:
BEGIN expected, got 'create'.
[2022-12-04 23:58:09] [65000][6550]
[2022-12-04 23:58:09] ORA-06550: line 1, column 7:
[2022-12-04 23:58:09] PLS-00103: Encountered the symbol "end-of-file" when expecting one of the following:

[2022-12-04 23:58:09] current cursor delete
[2022-12-04 23:58:09] exists prior
I don't think there's a problem with the syntax.
Also why does the DataGrip not allow DBMS_OUTPUT.PUT_LINE without the SYS. ? even though I've enabled the DBMSOUTPUT.
You can't have static DDL statements (like create procedure) within PL/SQL (you'd need to use dynamic SQL, but it's very rarely necessary anyway).
But if you're trying to declare a local procedure within your anonymous block - not create a permanent, stored procedure, then you don't need the create part:
declare
y number := 42;
procedure salutation(x IN OUT number) is begin
x:= x*10;
end salutation;
begin
SYS.DBMS_OUTPUT.PUT_LINE('hello');
-- call salutation here if you want...
salutation(y);
dbms_output.put_line(to_char(y));
end;
/
1 rows affected
dbms_output:
hello
420
fiddle
Note that I changed the argument to IN OUT - otherwise it would always be reset to null.
If you want to create a permanent stored procedure then do that separately, before you try to run your anonymous block:
create or replace procedure salutation(x IN OUT number) is begin
x:= x*10;
end salutation;
/
declare
y number := 42;
begin
SYS.DBMS_OUTPUT.PUT_LINE('hello');
-- call salutation here if you want...
salutation(y);
dbms_output.put_line(to_char(y));
end;
/
1 rows affected
dbms_output:
hello
420
fiddle
Also why does the DataGrip not allow DBMS_OUTPUT.PUT_LINE without the SYS. ?
That suggests your database is missing a public synonym for the package; not a DataGrip thing, you'd see the same behaviour using any client. You'd need to ask your DBA why it's missing and whether it can be reinstated. (I haven't included the schema prefix in the extra calls I added, but if those don't work for you then you'll need to add it.)
Here is a simple example using Toad for Data Analysts 3.0.1.1734. I have full permissions on the schema JSWEENEY.
Create the table
CREATE TABLE JSWEENEY.TEMP_SQL
(
SQL VARCHAR2(3000)
);
Create the procedure
CREATE OR REPLACE PROCEDURE JSWEENEY.SP_INSERT_SQL
IS
BEGIN
INSERT INTO JSWEENEY.TEMP_SQL(SQL) VALUES('SELECT * FROM TEMP_SQL');
COMMIT;
END JSWEENEY.SP_INSERT_SQL;
/
Execute the procedure:
BEGIN
JSWEENEY.SP_INSERT_SQL;
END;
The first error:
ORA-06550: line 2, column 11:
PLS-00905: object JSWEENEY.SP_INSERT_SQL is invalid
ORA-06550: line 2, column 2: PL/SQL: Statement ignored
Execute the procedure:
BEGIN
EXECUTE JSWEENEY.SP_INSERT_SQL;
END;
The second error:
ORA-06550: line 2, column 10:
PLS-00103: Encountered the symbol "JSWEENEY" when expecting one of the following: := . ( # % ; immediate The symbol ":=" was substituted for "JSWEENEY" to continue.
Any suggestions would be greatly appreciated.
When you compile the procedure you will get an error; if your client doesn't display that then you can query the user_errors view (or all_errors if you're creating it in a different schema) to see the problem. Here it will be complaining that:
LINE/COL ERROR
-------- -----------------------------------------------------------------
6/13 PLS-00103: Encountered the symbol "." when expecting one of the following:
;
It's valid to use the schema name in the create call; but not as part of the end. So if you need to specify the schema at all - which you don't if you're creating an object in your own schema, but your reference to permissions makes it sound like you aren't - then it should be:
CREATE OR REPLACE PROCEDURE JSWEENEY.SP_INSERT_SQL
IS
BEGIN
INSERT INTO JSWEENEY.TEMP_SQL(SQL) VALUES('SELECT * FROM TEMP_SQL');
COMMIT;
END SP_INSERT_SQL;
/
Your second error is because execute on its is a client command (in SQL*Plus and relations), not a PL/SQL statement. The error refers to immediate because PL/SQL does have an execute immediate statement which is used for dynamic SQL, not for making static calls to procedures. Your first syntax to run the procedure is correct, once the procedure itself is valid:
BEGIN
JSWEENEY.SP_INSERT_SQL;
END;
/
try this edited the SQL statement.
create table TEMP_SQL ( col1 varchar2(100));
CREATE OR REPLACE PROCEDURE SP_INSERT_SQL
AS
BEGIN
INSERT INTO TEMP_SQL SELECT * FROM TEMP_SQL;
COMMIT;
END SP_INSERT_SQL;
This is my code:
create or replace procedure p1
as
begin
create table emp_1 as (select * from emp);
end;
sql>exec p;
Then I get this error:
as ORA-06550: line 1, column 7:
PLS-00306: wrong number or types of arguments in call to 'P1'
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
You have several unclear issues :
Your procedure is p1 and you execute p. Why?
You can't execute create table statement inside a procedure like select or other DML. Use "EXECUTE IMMEDIATE" statement for that.
Why you are trying to create the table inside the procedure ? You can execute the statement directly with no procedure.
Try this ....
create or replace procedure p
as
begin
execute immediate 'create table emp_1 as (select * from emp)';
end;
sql>exec p;
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 have an object and I want to update an object table from with it dynamically. As an example
create or replace type typA as object
(
a number,
member procedure insert_self
);
/
create or replace type body typA is
member procedure insert_self is
begin
null;
end;
end;
/
create table typA_table of typA;
/
create or replace type body typA is
member procedure insert_self is
sql_stmt varchar2(200);
begin
sql_stmt := 'insert into typ_a_table values(self)';
execute immediate sql_stmt;
end;
end;
/
declare
l_typ typA;
begin
l_typ := typA(123);
l_typ.insert_self;
end;
But this returns an error due to the line which specifies 'self' in the sql_stmt.
Error report -
ORA-04063: table "SYSTEM.TYP_A_TABLE" has errors
ORA-06512: at "SYSTEM.TYPA", line 6
ORA-06512: at line 5
04063. 00000 - "%s has errors"
*Cause: Attempt to execute a stored procedure or use a view that has
errors. For stored procedures, the problem could be syntax errors
or references to other, non-existent procedures. For views,
the problem could be a reference in the view's defining query to
a non-existent table.
Can also be a table which has references to non-existent or
inaccessible types.
*Action: Fix the errors and/or create referenced objects as necessary.
Is there anyway to get around this error where I'm referencing variables that aren't easily converted to a string?
Can you not simply change your member procedure to something like the below, seems to work for me.
create or replace type body typA is
member procedure insert_self is
sql_stmt varchar2(200);
begin
insert into typ_a_table values(self.a);
end;
end;
