I'm trying to copy tables (schema+data) from one schema to another by using:
create table as select * from my_table
I want to do it from a certain table list, so I wrote a cursor
DECLARE
p_site nvarchar2(200);
v_cmd nvarchar2(1000);
v_tablename nvarchar2(100);
CURSOR export_running IS
SELECT tablename FROM TABLES_TABLE;
BEGIN
p_site:='site_name';
OPEN export_running;
LOOP
FETCH export_running INTO v_tablename;
EXIT WHEN export_running%NOTFOUND;
v_cmd:='create table '||v_tablename||' as select * from '||p_site||'.'||v_tablename;
execute immediate v_cmd;
END LOOP;
CLOSE export_running;
END;
When I run the code I get
PLS-00382: expression is of wrong type
ORA-06550: line 20, column 6:
PL/SQL: Statement ignored
06550. 00000 - "line %s, column %s:\n%s"
But if I print the statement and run it, it works well.
Datapump is not an option here.
I'm doing it on SQL Developer, Oracle version 12.1.
I have full privileges on both schemas.
Is it a known issue that I cannot dynamically create a table from one schema to the other?
Any suggestion?
Thanks!
Don't use NVARCHAR2 data type. From the documentation:
execute_immediate_statement
dynamic_sql_stmt
String literal, string variable, or string expression that represents
a SQL statement. Its type must be either CHAR, VARCHAR2, or CLOB.

I am attempting to create a Oracle stored procedure which creates partitioned tables based off of a table containing the table names and the column to be partitioned with. A separate PL/SQL block iterates through the table and calls the procedure with the table name and the column name.
Procedure:
create or replace PROCEDURE exec_multiple_table_create (
table_name IN VARCHAR2,
column_name IN VARCHAR2
) IS
stmt VARCHAR2(5000);
tablename VARCHAR2(50);
columnname VARCHAR2(50);
BEGIN
tablename := table_name;
columnname := column_name;
-- DBMS_OUTPUT.PUT_LINE(tablename);
-- DBMS_OUTPUT.PUT_LINE(columnname);
stmt := 'create table '
|| TABLENAME
|| '_temp as (select * from '
|| COLUMNNAME
|| ' where 1=2)';
EXECUTE IMMEDIATE stmt
USING IN table_name, column_name;
stmt := 'alter table '
|| tablename
|| '_temp modify partition by range('
|| columnname
|| ')
(PARTITION observations_past VALUES LESS THAN (TO_DATE(''20000101'',''YYYYMMDD'')),
PARTITION observations_CY_2000 VALUES LESS THAN (TO_DATE(''20010101'',''YYYYMMDD'')),
PARTITION observations_CY_2001 VALUES LESS THAN (TO_DATE(''20020101'',''YYYYMMDD'')),
PARTITION observations_CY_2002 VALUES LESS THAN (TO_DATE(''20030101'',''YYYYMMDD'')),
PARTITION observations_CY_2003 VALUES LESS THAN (TO_DATE(''20040101'',''YYYYMMDD'')),

PARTITION observations_CY_2010 VALUES LESS THAN (TO_DATE(''20110101'',''YYYYMMDD'')),
PARTITION observations_FUTURE VALUES LESS THAN ( MAXVALUE ) )';
EXECUTE IMMEDIATE stmt
USING IN table_name, column_name;
RETURN;
END exec_multiple_table_create;
The PL/SQL block which is using the stored proc is:
BEGIN
FOR partition_item IN (
SELECT
table_name,
partition_column
FROM
partition_table
) LOOP
exec_multiple_table_create(partition_item.table_name, partition_item.partition_column);
END LOOP;
END;
Now, when I try executing the thing, this is what I am seeing:
Error report -
ORA-06550: line 9, column 9:
PLS-00905: object SCG_MYACCT_CUSTOMPC.EXEC_MULTIPLE_TABLE_CREATE is invalid

*Cause: Usually a PL/SQL compilation error.
*Action:
I have a feeling that I am missing something. Please let me know what it is. The table containing the reference data exists and contains data.
I have tried refreshing the table, rewriting and modifying the pl/sql block & the procedure code. Nothing seems to be working.
Thanks in advance.
UPDATE 1:
There was a glitch in the stored procedure where I needed to refer to the tablename rather than the columnname in the code above. However, I am getting a different error right now.
Error report -
ORA-06546: DDL statement is executed in an illegal context

*Action: Use EXECUTE IMMEDIATE without USING and INTO clauses to execute
the DDL statement.
Please help me out with this as well.
UPDATE 2:
I removed the USING part of the EXECUTE IMMEDIATE statement. That seemed to take care of the error I posted. Getting a different error with versions now:
Error starting at line : 1 in command -

I want to write an update script for my oracle db. I want to replace old XML node values with new ones. But I need to do this for many values so I wanna outsource the logic in a procedure.
This is what I've come up with.
CREATE OR REPLACE PROCEDURE MY_PROCEDURE(
old_name IN NVARCHAR2,
new_name IN NVARCHAR2
)
AS
BEGIN
UPDATE
MY_TABLE
SET
ENTITY = UPDATEXML(ENTITY, '/*/Section', '<Section>' || new_name || '</Section>', 'xmlns="http://foo.bar.com/baz"')
WHERE
EXTRACTVALUE(ENTITY, '/*/Section', 'xmlns="http://foo.bar.com/baz"') = old_name;
END;
This is actually working really well - when I don't use string concatenation in UPDATEXML(). When I start using concatenation the execution of the procedure stops working / starts to throw exceptions.
I've also tried CONCAT(CONCAT('<Section>', new_name), '</Section>') instead of the ||-Operator. Didn't work out either.
The exception I get running the procedure in Oracle SQL Developer
ORA-06550: line 2, column 5:
PLS-00905: object MY_DB.MY_PROCEDURE is invalid
ORA-06550: line 2, column 5:

My ultimate goal is far more complex than this, but this is the cut down version of what is causing my error. I want to put some rows into a temporary table (actually several temp tables, but I can't get by this first hurdle). Here is my PL/SQL;
DECLARE
type L1_store is table of MyTable%rowtype;
L1 L1_store;
BEGIN
select
* bulk collect
into L1
from MyTable
WHERE 1=1
and length(MyColumn1) = 2;
select
L1.MyColumn1
,L1.MyColumn2
from L1;
END;
And here is the error I get;
ORA-06550: line 19, column 6:
PL/SQL: ORA-00942: table or view does not exist
ORA-06550: line 16, column 1:

*Cause: Usually a PL/SQL compilation error.
*Action:
The line numbers may be incorrect as I have edited the actual PL/SQL for clarity
****EDIT****
OK, so I originally accepted the answer offered below as it looks like it answers my question, and I can see how I could use it. However, for clarity, here is my ultimate goal, in case there is a better answer than the one I have in my head.
If I was just doing this in SQL I would do something like;
with L1 as
(select * from table),
L2 as
(select * from anothertable)
select L1.Column
from L1
left join L2 on L1.somecolumn = L2.somecolumn
I don't know if this helps or hinders, but thanks all in anticipation of your continued patience.
type L1_store is table of MyTable%rowtype; is not a temporary table; it is a collection data type declared in the PL/SQL scope and cannot be used in the SQL scope. Similarly, %ROWTYPE is a PL/SQL construct.
If you want to use a collection in SQL then declare it in the SQL scope:
CREATE TYPE mytable_data is OBJECT (
mycolumn1 VARCHAR2(50),
mycolumn2 NUMBER,
mycolumn3 DATE
);
CREATE TYPE mytable_data_table IS TABLE OF mytable_data;
so for some test data:
CREATE TABLE MyTable(
mycolumn1 VARCHAR2(50),
mycolumn2 NUMBER,
mycolumn3 DATE
);
INSERT INTO MyTable VALUES ( 'AA', 42, SYSDATE );
Then you can do:
DECLARE
L1 mytable_data_table;
BEGIN
select mytable_data( mycolumn1, mycolumn2, mycolumn3 )
bulk collect into L1
from MyTable
WHERE length(MyColumn1) = 2;
FOR i IN 1 .. L1.COUNT LOOP
DBMS_OUTPUT.PUT_LINE( L1(i).mycolumn1 || ' ' || l1(i).mycolumn2 );
END LOOP;
END;
/
Which outputs:
AA 42
db<>fiddle here
The problem here seems to be the second select in the block. If you're trying to select the data from the record, I would be inclined to put it into a FOR loop. I.e, something like this:
for i in 1 .. L1.count() LOOP
dbms_output.put_line (L1(i).MyColumn1);
end loop;
You could assign the value of MYColumn1 to a variable or use it in some other way.
I'm trying to run below pl/sql block but I'm getting error:
set serveroutput on
declare
rowBefore VARCHAR2(32000);
myschema VARCHAR2(32000) := 'abc';
mytable VARCHAR2(32000) := 'table1';
param1 VARCHAR2(32000) := 'Tom';
begin
select count(*) into rowBefore from myschema.mytable where colA = param1;
--select count(*) into rowBefore from abc.table1 where colA = 'Tom';
DBMS_OUTPUT.PUT_LINE(rowBefore);
End;
How to correctly use my all parameters into select statement?

*Cause: Usually a PL/SQL compilation error.
*Action:
You can't use a variable as an identifier in a SQL statement. It is looking for a table that is actually called mytable - not one with the value of the variable with that name as you expect. And the same for the schema.
From the documentation:
If the statement is a SELECT statement, the PL/SQL compiler removes the INTO clause.
The PL/SQL compiler sends the statement to the SQL subsystem.
The SQL subsystem checks the syntax of the statement.
If the syntax is incorrect, the compilation of the PL/SQL unit fails. If the syntax is correct, the SQL subsystem determines the names of the tables and tries to resolve the other names in the scope of the SQL statement.
...
It tries to resolve other names, e.g. functions; but table names (and schema names, and column names) have to be valid to the SQL parser.
You have to use dynamic SQL to create a string that contains the statement, concatenating in the identifiers:
execute immediate 'select count(*) from ' || myschema ||'.'|| mytable
|| ' where colA = :value'
into rowBefore using param1;
If you print out that generated statement with dbms_output you should see it matching the commented-out version, except for the use of a bind variable for the columns value. That would also help highlight any errors - like not including whitespace between the concatenated parts of the statement, which is a common and easy mistake.
It's often a good idea to build the statement as a string variable to make such debugging easier:
declare
...
v_stmt varchar2(4000):
begin
v_stmt := 'select count(*) from ' || myschema ||'.'|| mytable
|| ' where colA = :value';
-- for debugging
dbms_output.put_line(v_stmt);
-- and run it
execute immediate vStmt into rowBefore using param1;
...
If you are really getting the identifiers passed in by a user or client you should validate them to avoid unexpected errors and SQL injection attacks. Also, if the identifiers might be case sensitive (i.e. schemas/tables created with quoted identifiers) then you may need to add double-quotes to the generated statement, and make sure the variables are the correct case.
error is ORA-942: table or view does not exists. run first below query and see if error still occurs.
-- should you use abc.table1, instead of myschema.mytable?
select count(*) rowBefore from myschema.mytable where colA = 'a';
if there is still error, then fix the SELECT statement first before you use it in the PL/SQL block.
I am trying to create table dynamically in Oracle stored procedure.
I have created create table sql in the string variable.
Below is the sql snapshot and error.
Procedure is getting compiled without any issue. But when trying to execute the procedure, I am getting runtime error. I am getting the issue because of to_char expression.
CREATE OR REPLACE PROCEDURE TESTPROC12(P_TMP_Table IN VARCHAR2) AUTHID CURRENT_USER IS
V_SQL_STMT1 varchar2(1000);
V_TMP_Table varchar2(100);
BEGIN
V_TMP_Table := concat('TMP', to_char(sysdate,'MMDDYYYYHH24MISSSSS'));
V_SQL_STMT1 := 'CREATE TABLE '|| V_TMP_Table||' AS
SELECT * from TMP_STMTSENT2 where rowid in (select min(rowid) from '|| P_TMP_Table||'
group by CUSTOMER_RELATIONSHIP_ID, to_char(''STATEMENT_PROCESSED_DATE'',''MM/DD/YYYY''))';
EXECUTE IMMEDIATE V_SQL_STMT1;
END;
Procedure - I need to use to_char.
EXEC TESTPROC12('TMP_STMTSENT2')
Error starting at line 20 in command:
EXEC TESTPROC12('TMP_STMTSENT2')
Error report:
ORA-01722: invalid number
ORA-06512: at "EDLVY.TESTPROC12", line 15
ORA-06512: at line 1
01722. 00000 - "invalid number"
*Cause:
*Action:
The generated and executed statement could look like the following:
CREATE TABLE 10222013023309188 AS SELECT * from TMP_STMTSENT2 where rowid in (select min(rowid) from qeoiwqeoiwq group by CUSTOMER_RELATIONSHIP_ID, to_char('STATEMENT_PROCESSED_DATE','MM/DD/YYYY'))
The problem could be with 'STATEMENT_PROCESSED_DATE', which is not a date. Try sysdate instead and see if it works.
Take a look at the docs. You are passing the string 'STATEMENT_PROCESSED_DATE' to to_char(). Maybe you want to pass the column or value STATEMENT_PROCESSED_DATE instead?
A good way to do what you are pusuing is using Oracle Temporary Tables
