suffixing date in the EXECUTE IMMEDIATE statement
Hi could one please let me know how I can the suffix of the name of the table to the year, which the calculation is being in the select statement. Output should be as an example: test_2007declare
abc number;
begin
select (to_char(sysdate, 'YYYY') - 4) into abc from dual;
EXECUTE IMMEDIATE 'CREATE TABLE test_&abc as select * from emp where 1=2';
end;
You can do it like this
BEGIN
EXECUTE IMMEDIATE
'CREATE TABLE test_'
|| (TO_CHAR ( SYSDATE, 'YYYY') - 4)
|| ' as select * from emp where 1=2';
END;
You can use your variable as well, if this can change dynamically.
DECLARE
abc NUMBER;
BEGIN
SELECT (TO_CHAR ( SYSDATE, 'YYYY') - 4) INTO abc FROM DUAL;
EXECUTE IMMEDIATE 'CREATE TABLE test_'||abc||' as select * from emp where 1=2';
END;

The concatenation of the EXECUTE IMMEDIATE statement.
Hi all
The situation is that I am trying to find all customers whose Date of birth (DOB) is greater than or equal to 150 days. Unfortunately, when I run this SQL I get the error message:
(1) ORA-00904: "FEB": invalid identifier
(1) ORA-06512: at line 4 level
I'm not sure what I should do to solve this problem, I hope you can help.
Note: I have to encapsulate this statement in an immediate execution due to problems of roles/Privilidge. In the full version, I also use AUTHID CURRENT_USER.
Edited by: DaveyB February 23, 2012 08:39DECLARE curr_date Date := SYSDATE; BEGIN EXECUTE IMMEDIATE ' SELECT cust_name, cust_dob, -- date of birth cust_shoe_size FROM tblCustDetails c WHERE SUBSTR(c.cust_name, 1,7) = ''Bob'' AND cust_dob >= NEXT_DAY(' || curr_date ||' - 150 , ''SATURDAY'') '; END;
The right way to use dynamic queries like this would get stuck in the variables you use... for example
DECLARE curr_date Date := SYSDATE; BEGIN EXECUTE IMMEDIATE ' SELECT cust_name, cust_dob, -- date of birth cust_shoe_size FROM tblCustDetails c WHERE SUBSTR(c.cust_name, 1,7) = ''Bob'' AND cust_dob >= NEXT_DAY(:1 - 150 , ''SATURDAY'') ' USING curr_date; END;
However, you also have to take into account the fact that the results of the query are currently disappearing into the ether, so you need an INTO statement...
DECLARE curr_date Date := SYSDATE; BEGIN EXECUTE IMMEDIATE ' SELECT cust_name, cust_dob, -- date of birth cust_shoe_size FROM tblCustDetails c WHERE SUBSTR(c.cust_name, 1,7) = ''Bob'' AND cust_dob >= NEXT_DAY(:1 - 150 , ''SATURDAY'') ' INTO var1, var2, var3 USING curr_date; END;
ensure that your variables are declared as appropriate, and then...
... you have to take into account the possibility that there is more than 1 line returned, in which case you will have the results of the query to a collection.
Of course, it is useless for dynamic SQL statements in the first place...
DECLARE curr_date Date := SYSDATE; BEGIN SELECT cust_name, cust_dob, -- date of birth cust_shoe_size INTO var1, var2, var3 FROM tblCustDetails c WHERE SUBSTR(c.cust_name, 1,7) = 'Bob' AND cust_dob >= NEXT_DAY(curr_date - 150 , 'SATURDAY'); END;
still, you should always take into account the bulk collection in a collection if it were going to be more than one row returned.

Creating external Tables using the EXECUTE IMMEDIATE in PL/SQL
Hi guys,.
I am trying to create an external Table using the EXECUTE IMMEDIATE in a procedure and I managed to compile and no errors were generated. But when I try to run it from sql using the exec command I get the following error:
------------------------------------------------------------------------
ERROR on line 5:
ORA-00911: invalid character
ORA-06512: at "GEO. TEST_DDL', line 4
ORA-06512: at line 5
-------------------------------------------------------------------------
I tried to check the whole statement to create the external table, but I can't find where is the error. Surprisingly, if I simply run the command table create external on sqlplus it works, but not a procedure.
If anyone can help with ideas or experience?
Geoffrey KossamiThe error means that there is an identifier somewhere that starts with a nonalphanumeric. This is a typical mistake of editing. A procedure compiles correctly is not of course because the underlying dynamic sql running is OK. Which of course only be resolved when you try to run it.
There is certainly a problem with the text you provide to be run as a piece of dynamic sql code. You should try to watch it with dbms_output and run this code in sqlplus. But your problem is with the code you run as dynamic PL/SQL, it is not itself compilable.

Published by: user652279 on September 16, 2009 11:47Well, dynamic sql is executed in a separate context and scope. V_barg_unit stated in your code is therefore not visible in the dynamic PL/SQL block you run. You can pass block dynamic PL/SQL using the variable binding and the USING clause:
DECLARE cmd VARCHAR2 (4000); v_barg_unit VARCHAR2 (10) := 'ABC'; v_bg_group VARCHAR2 (10) := ' '; CURSOR abc IS SELECT * FROM test_dynamic_if_tbl; BEGIN FOR c1 IN abc LOOP cmd := 'declare v_barg_unit VARCHAR2 (10); Begin v_barg_unit := :v_barg_unit; If ' || c1.condition || ' THEN ' || c1.result_val || ' ; End if; End;'; DBMS_OUTPUT.put_line ('cmd: ' || cmd); EXECUTE IMMEDIATE cmd USING v_barg_unit,OUT v_bg_group; DBMS_OUTPUT.put_line ('Condition: ' || c1.condition); DBMS_OUTPUT.put_line ('result_value: ' || c1.result_val); DBMS_OUTPUT.put_line ('v_bg_group: ' || v_bg_group); END LOOP; END;
However, since you do not know what name will be stored in test_dynamic_if_tbl my suggestion is not a generic solution.

Maximum size of EXECUTE IMMEDIATE
Hellou everyone,
I would like to ask if there is a way how to run the dynamic SQL CREATE or VIEW of REPLACE command more than 32 KB of wholesale. Because the EXECUTE IMMEDIATE statement can run up to 32 k (greater length of variable plsql chain) chain
Is there a way how children Ridge or replace the command?
Or I need to revrite using DBMS_SQL.
Thank you.
(a) WHY? If you want to dynamically create views? This is not recommended because your application/database should be designed at the time of the design, not running.
(b) If you are on 11 g, you can use the CLOB datatype with immediate execution, so there is no 32 K limit.
(c) If you are before 11 g you need to update, but if you can't then the following example is how you do it using DBMS_SQL.

If you have N tables with columns of M your code will run statements N * Mr. If the tables are large, it might take some time. Now how about double quotes. You may receive error on the basis I assumed you have names of tables/columns composed of several words. You must include these names in quotation marks. Discover Oracle naming rules.

end if;
end loop;

end;Your immediate question seems to be answered.
I would like to point out a few problems with your code, however.
First of all, it seems pointless to use dynamic SQL here - you can use a static SQL statement to get the same data. You can use static SQL, you should.
Secondly, if you want to use dynamic SQL statements, you should really use bind variables. Something like
v_stmt := 'select NULLABLE from DBA_TAB_COLUMNS WHERE TABLE_NAME = :1 and COLUMN_NAME in (select column_name from DBA_IND_COLUMNS where INDEX_NAME= (select "INDEX_NAME" from DBA_INDEXES where TABLE_NAME =':2 and UNIQUENESS =''UNIQUE''))'; execute immediate v_stmt bulk collect into v_ct using r_tbl, r_tbl;
Third, your deepest query is to select the literal 'INDEX_NAME' rather than the name of the actual index. Unless you happen to have an index named INDEX_NAME, who is likely to be a mistake.
v_stmt := 'select NULLABLE from DBA_TAB_COLUMNS WHERE TABLE_NAME = :1 and COLUMN_NAME in (select column_name from DBA_IND_COLUMNS where INDEX_NAME= (select INDEX_NAME from DBA_INDEXES where TABLE_NAME =':2 and UNIQUENESS =''UNIQUE''))'; execute immediate v_stmt bulk collect into v_ct using r_tbl, r_tbl;
Fourth, unless you can be sure that the table has a unique index, your query will return an error because the deepest returns multiple lines.
v_stmt := 'select NULLABLE from DBA_TAB_COLUMNS WHERE TABLE_NAME = :1 and COLUMN_NAME in (select column_name from DBA_IND_COLUMNS where INDEX_NAME in (select INDEX_NAME from DBA_INDEXES where TABLE_NAME =':2 and UNIQUENESS =''UNIQUE''))'; execute immediate v_stmt bulk collect into v_ct using r_tbl, r_tbl;

I have plsql-variable with CLOB datatype. It contains the source code of a package body. The size of the variable does not fit into 'varchar2' data type, it is larger.
Now, I want to run a "EXECUTE IMMEDIATE" statement to create my package body defined in my CLOB variable.
How can I use the "EXECUTE IMMEDIATE"?
Note that "EXECUTE IMMEDIATE" does not allow for CLOB-variable as an argument.
Note that "EXECUTE IMMEDIATE" allows "varchar2" - variables as arguments but "varchar2" contains maximum only some 32 KB of data.

Maybe it's possible to run something like
"EXECUTE IMMEDIATE v1 | v2 | v3»
where v1, v2, v3 are of type varchar2 and altogether they contain ca 100K of data and execute immediately would succeed?

Here is the list of question I see in this code.
1. in the SQL string, you must have a
after the keyword and before the GROUP BY keyword. 2. you should not use ';' in EXECUTE IMMEDIATE. You must remove it.
3. the result set returned by the EXECUTE IMMEDIATE should be stored in a Variable. You use the INTO LEDGES INTO clause or in BULK to this effect.
