Home -> Community -> Mailing Lists -> Oracle-L -> RE: dynamic dynamic sql within a procedure - ora_00911
I got it ... but had to go about it with a cursor, not very elegant but I
didn't have alot of time to think it over.. This is the update procedure
I have the insert, select, delete procs working as well. Right now I am
trying to fit the pieces together into a package. There are some caveats to
this .... I haven't built in a check for the column lengths when you add the
P_ or V_, it assumes you have ctrl_date or ctrl_user in each table.
This should get you going. I am excited about this because we use alot of audit tables and triggers here so I can modify this code to do this...
If someone comes up with something more elegant then what I have I would be interested to see it.
The user that runs the procs has dba privs and create and alter any procedure privs.
Have fun.

I have been trying to write an sql script that will do the same thing. I am having a bear of a time. I can get the pieces easily enough but I can't put them together in a meaningful way. I have been trying with a union to get the create or replace part unioned to the stuff from source$. If you comeup with a solution let me know, if I do I will share too.

Ruth,
What I am trying to do is create a code generator..... I am creating new
tables and want to create insert, delete, update and select procedures
for all of the tables. Rather than do them one by one and having to fix
them every time the developers want to change the name, etc.... I
decided to try to build a code generator. So I want my admin procedure
which is passed an owner and table name to spit out
select, delete, insert and update procedure for that user. This is what I
have which WORKS for the select all proc.
You need to create a type package for the cursorvar and the dba user needs
create any and drop any priveledges for procedures.
It will have to be executed by the user exec
TABLE_NAME_select_all_proc in
this case.
v_sql := 'CREATE or REPLACE PROCEDURE '|| upper(P_OWNER_NAME) ||'.'|| upper(P_TABLE_NAME) || '_SELECT_ALL_PROC ( ' || chr(10)||
' P_ALL_ROWS_CURSOR out types.cursorvar ' || chr(10) || ' ) is ' || chr(10) || ' Begin ' || chr(10) || ' open P_ALL_ROWS_CURSOR for ' || chr(10) || ' select * ' || chr(10) || ' from ' || upper(P_OWNER_NAME) ||'.'|| upper(P_TABLE_NAME) || chr(10)|| ' order by 1; ' || chr(10)||
v_sql := rtrim(v_sql,' ');
execute immediate v_sql;
This is what I ended up for this one.... I was doing to much work for the
select all procedure , but I face the problem with delete, select
and insert where I need to dynamic dynamic.... I am going to try
to execute
sql into a variable I think then try to || them together
Unless someone here comes up with a better plan...:)
Thanks,
Kathy

Once this procedure is created, how do you run it. I asked my boss, the
super duhveloper, but he didn't know. I know this is a stupic
question, but
I don't do much sql.
Thanks in advance,
Ruth

Kathy,
I modified your proc a bit and got it to create the procedure for
me - but I
was missing the types.cursorvar variable. I'm assuming that
you have this
created in your database someplace.
This is a pretty interesting idea! Here is the new proc:
CREATE OR REPLACE PROCEDURE Generate_Select_All_Proc ( P_OWNER_NAME IN DBA_TABLES.OWNER%TYPE, P_TABLE_NAME IN DBA_TABLES.TABLE_NAME%TYPE) IS
err_num BINARY_INTEGER;
err_msg VARCHAR(300);
v_sql VARCHAR2(2000) := NULL;
BEGIN v_sql := 'CREATE OR REPLACE PROCEDURE ' ||
P_TABLE_NAME || '_SELECT_ALL_PROC ( ' ||
' P_ALL_ROWS_CURSOR OUT types.cursorvar ' ||
' ) IS ' ||
' BEGIN ' ||
' OPEN P_ALL_ROWS_CURSOR FOR ' ||
' SELECT * FROM ' ||
P_OWNER_NAME||'.'|| P_TABLE_NAME ||
' ORDER BY 1; ' ||
'END;';
v_sql := RTRIM(v_sql,' ');
dbms_output.put_line (SUBSTR(v_sql,1,255)); dbms_output.put_line (SUBSTR(v_sql,256,255));
EXECUTE IMMEDIATE v_sql;
EXCEPTION
WHEN OTHERS
THEN
err_num := SQLCODE;
err_msg := SQLERRM;
RAISE_APPLICATION_ERROR(-20011,'Oracle error '||err_num||
'generate_select_all_proc : '||err_msg);
END Generate_Select_All_Proc;
Good Luck!

Subject: dynamic dynamic sql within a procedure - ora_00911
Ok, I am trying to create a sql generator. I am trying to start
out simple.
What I want to do it to pass an owner, table name into a
procedure and have
it create a procedure for this owner table name
In this case I want to create a procedure that will create a procedure
tablename_select_all_proc that will select * from owner.tablename
The syntax when I pull it apart looks ok. But when I run it I get an ora_00911, the procedure and output are below.
It looks to me as if it is splicing the lines up. Instead of using the
execute immediate do I have to use dbms_sql to parse and fetch
this sql? Or
is there a way to do this?
platform 10G, Solaris.
Thanks,
Kathy
