SQL group by and having

I have a table having columns business_name ,sales,state,zip.
I would like to know count of businesses having sales 0-50 and
count of businesses having sales50-100, and 100-150 and so on.
can i write single query to gent count of business for all these ranges,instead of
writing seperate query for each range. If possible please tell me how?

SELECT sum(case
              when sales between 0 and 50 then 1
              else 0
           end
          ) sales_0_50
      ,sum(case
              when sales between 51 and 100 then 1
              else 0
           end
          ) sales_51_100
      ,sum(case
              when sales between 101 and 150 then 1
              else 0
           end
          ) sales_101_150
      ,sum(case
              when sales > 150 then 1
              else 0
           end
          ) sales_over_150

Group by and having

Hi,
According to standard sql, we must have:
select ___
from ___
where ___
group by ___
having ___;
However, I tried do the query with the following order:
select ___
from ___
where ___
having ___
group by ___;
And I received the same result.
Does anybody knows the difference between those two orders? Are they always give the same result?
Thank You

According to the 9i documentation:
Specify GROUP BY and HAVING after the where_clause and CONNECT BY clause. If you specify both GROUP BY and HAVING, they can appear in either order.
Which you've got to admit does match your experience.
Cheers, APC

GROUP BY and HAVING can appear in either order.

Hi,
please give me one example for the following line i found it in "19-28 Oracle Database SQL Language Reference".
If you specify both GROUP BY and HAVING, then they can appear in
either order.

Use of group by and having clause

hi frnds
can anybody explain me the use of group by an having clause in select state ment

Hi Rohit,
1. GROUP BY f1 ... fn
2. GROUP BY (itab)
1. GROUP BY f1 ... fn
Effect
Groups database table data in a SELECT command on one line in the result set. A group is a set of lines which all have the same values in each column determined by the field descriptors f1 ... fn.
... GROUP BY f1 ... fn always requires a list in the SELECT clause. If you use field descriptors without an aggregate funciton in the SELECT clause, you must list them in the GROUP BY f1 ... fn clause.
Example
Output the number of passengers, the total weight and the average weight of luggage for all Lufthansa flights on 28.02.1995:
TABLES SBOOK.
DATA: COUNT TYPE I, SUM TYPE P DECIMALS 2, AVG TYPE F.
DATA: CONNID LIKE SBOOK-CONNID.
SELECT CONNID COUNT( * ) SUM( LUGGWEIGHT ) AVG( LUGGWEIGHT )
       INTO (CONNID, COUNT, SUM, AVG)
       FROM SBOOK
       WHERE
         CARRID   = 'LH'       AND
         FLDATE   = '19950228'
       GROUP BY CONNID.
WRITE: / CONNID, COUNT, SUM, AVG.
ENDSELECT.
Note
... GROUP BY f1 ... fn is not supported for pooled and cluster tables.
2. GROUP BY (itab)
Effect
Works like GROUP BY f1 ... fn if the internal table itab contains the list f1 ... fn as ABAP source code. The internal table itab can only have one field. This field must be of the type C and should not be more than 72 characters long. itab must be enclosed in parentheses and there should be no blanks between the parentheses and the table name.
Note
The same restrictions apply to this variant as to GROUP BY f1 ... fn.
Example
Output all Lufthansa departure points with the number of destinations:
TABLES: SPFLI.
DATA:   BEGIN OF WA.
          INCLUDE STRUCTURE SPFLI.
DATA:     COUNT TYPE I.
DATA:   END OF WA.
DATA:   WA_TAB(72) TYPE C,
        GTAB LIKE TABLE OF WA_TAB,
        FTAB LIKE TABLE OF WA_TAB,
        COUNT TYPE I.
CLEAR: GTAB, FTAB.
WA_TAB = 'COTYFROM COUNT( * ) AS COUNT'. APPEND FTAB.
APPEND WA_TAB TO FTAB.
WA_TAB = 'CITYFROM'.
APPEND WA_TAB TO GTAB.
SELECT DISTINCT (FTAB)
       INTO CORRESPONDING FIELDS OF WA
       FROM SPFLI
       WHERE
         CARRID   = 'LH'
       GROUP BY (GTAB).
WRITE: / WA-CITYFROM, WA-COUNT.
ENDSELECT.

Question about GROUP BY and HAVING

Good afternoon,
I have the following query which returns the desired result (set of students who take CS112 or CS114 but not both). I wanted to "condense" it into a single SELECT statement (if that is at all possible - DDL to execute the statement is provided at the end of this post):
-- is this select distinct * and its associated where clause absolutely
-- necessary to obtain the result ?
select distinct *

        select s.sno,

;I have searched for a document that completely defines the sequence in which the clauses are executed. I have found tidbits here and there but not something complete. I realize that my running into problems like this one is due to my lack of understanding of the sequence and the scope of the clauses that make up a statement. Because of this, I cannot even tell if it is possible to write the above query using a single select statement. Pardon my bit of frustration...
Thank you for your help,
John.

Hi, John,
Just use the aggregate SUM function.
        select s.sno,
               s.sname,
               s.age,
               sum(case when t.cno in ('CS112', 'CS114')
                        then 1
                        else 0
                   end) as takes_either_or_both
          from student s join take t
                           on (s.sno = t.sno)
       GROUP BY s.sno,
                s.sname,
              s.age
       HAVING sum(case when t.cno in ('CS112', 'CS114')
                        then 1
                        else 0
                   end) = 1;Analytic functions are computed after the WHERE- and HAVING clause have been applied. To use the results of an analytic fucntion in a WHERE- or HAVING clause, you have to compute it in a sub-query, and then you can use it in a WHERE- or HAVING clause of a super-query.

Find duplicate records withouyqusing group by and having

I know i can delete duplicate records using an analytic function. I don't want to delete the records, I want to look at the data to try to understand why I have duplicates. I am looking at tables that don't have unique constraints (I can't do anything about it). I have some very large tables. so I am trying to find a faster way to do this.
for example
myTable
col1 number,
col2 number,
col3 number,
col4 number,
col5 number)
My key column is col1 and col2 (it is not enforced in the database). So I want to get all the records that have duplicates on these fields and put them in a table to review. This is a standard way to do it, but it requires 2 full table scans of very large tables (many, many gigabtytes. one is 150 gbs and not partitioned), a sort, and a hash join. Even if i increase sort_area_size and hash_area_size, it takes a long time to run..
create table mydup
as
select b.*
from (select col1,col2,count(*)
from myTable
group by col1, col2
having count(*) > 1) a,
myTable b
where a.col1 = b.col1
and a.col2 = b.col2
I think there is a way to do this without a join by using rank, dense_rank, or row_number or some other way. When I google this all I get is how to "delete them". I want to analyze them a nd not delete them.

create table mytable (col1 number,col2 number,col3 number,col4 number,col5 number);
insert into mytable values (1,2,3,4,5);
insert into mytable values (2,2,3,4,5);
insert into mytable values (3,2,3,4,5);
insert into mytable values (2,2,3,4,5);
insert into mytable values (1,2,3,4,5);

Need Help With SQL GROUP BY and DISTINCT

I am working on a project and need to display the total of each order based on the order id. For instance I want to display the order id, customer id, order date, and then the extension price (ol_quantity * inv_price).
I would then like a total displayed for order # 1 and then move on to order #2.
Here is my SQL code :
SELECT DISTINCT orders.o_id, customer.c_id, inv_price * ol_quantity
FROM orders, customer, inventory, order_line
GROUP BY orders.o_id, customer.c_id, inv_price, ol_quantity
ORDER BY orders.o_id;
When my code is run it displays the order id, customer id and inv_price * quantity (extension price) but no order total for the order number and a new group is not started when a new order number is started....they are all clumped together.
Any help is greatly appreciated!!

Any help is greatly appreciated!!Sorry, it's unclear what you want.
Whenever you post a question, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only), and the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say what version of Oracle you're using.
Do you want the output to contain one row for each row in the table, plus an extra row for each distinct order, showing something about the order as a whole (e.g., total inv_price or average extension_price)? If so, you need GROUP BY ROLLUP or GROUP BY GROUPING SETS .
If you want one row of output for each row of the table, but you want to include something that reflects the group as a whole (again, e.g, total inv_prive or average extension_pcie), then you can us analytic functions. (Most of the aggregate functions, such as SUM and AVG have analytic counterparts that can get the same results without collapsing the result set down to one row per group.)
Here's an example of how to use GROUP BY GROUPING SETS.
Way we're interested in employees' salary and commission from the scott.emp table:
SELECT       deptno

                         , (deptno, ename)
ORDER BY deptno
,            ename
;Notice that we're displaying SUM (sal) on each row. Most of the rows in the output are "groups" consisting of only one row from the table, so the SUM (sa) for that goup will be the sal for the one row in the group.

Group by clause and having clause in select

hi frnds
plz give me some information of group by and having clause used in select statement with example
thanks

The Open SQL statement for reading data from database tables is:
SELECT      <result>
INTO      <target>
FROM      <source>
[WHERE    <condition>]
[GROUP BY <fields>]
[HAVING   <cond>]
[ORDER BY <fields>].
The SELECT statement is divided into a series of simple clauses, each of which has a different part to play in selecting, placing, and arranging the data from the database.
You can only use the HAVING clause in conjunction with the GROUP BY clause.
To select line groups, use:
SELECT <lines> <s1> [AS <a1>] <s2> [AS <a2>] ...
               <agg> <sm> [AS <am>] <agg> <sn> [AS <an>] ...
       GROUP BY <s1> <s2> ....
       HAVING <cond>.
The conditions <cond> that you can use in the HAVING clause are the same as those in the SELECT clause, with the restrictions that you can only use columns from the SELECT clause, and not all of the columns from the database tables in the FROM clause. If you use an invalid column, a runtime error results.
On the other hand, you can enter aggregate expressions for all columns read from the database table that do not appear in the GROUP BY clause. This means that you can use aggregate expressions, even if they do not appear in the SELECT clause. You cannot use aggregate expressions in the conditions in the WHERE clause.
As in the WHERE clause, you can specify the conditions in the HAVING clause as the contents of an internal table with line type C and length 72.
Example
DATA WA TYPE SFLIGHT.
SELECT   CONNID
INTO     WA-CONNID
FROM     SFLIGHT
WHERE    CARRID = 'LH'
GROUP BY CONNID
HAVING   SUM( SEATSOCC ) > 300.
WRITE: / WA-CARRID, WA-CONNID.
ENDSELECT.
This example selects groups of lines from database table SFLIGHT with the value LH for CARRID and identical values of CONNID. The groups are then restricted further by the condition that the sum of the contents of the column SEATSOCC for a group must be greater than 300.
The <b>GROUP BY</b> clause summarizes several lines from the database table into a single line of the selection.
The GROUP BY clause allows you to summarize lines that have the same content in particular columns. Aggregate functions are applied to the other columns. You can specify the columns in the GROUP BY clause either statically or dynamically.
Specifying Columns Statically
To specify the columns in the GROUP BY clause statically, use:
SELECT <lines> <s1> [AS <a 1>] <s 2> [AS <a 2>] ...
               <agg> <sm> [AS <a m>] <agg> <s n> [AS <a n>] ...
       GROUP BY <s1> <s 2> ....
To use the GROUP BY clause, you must specify all of the relevant columns in the SELECT clause. In the GROUP BY clause, you list the field names of the columns whose contents must be the same. You can only use the field names as they appear in the database table. Alias names from the SELECT clause are not allowed.
All columns of the SELECT clause that are not listed in the GROUP BY clause must be included in aggregate functions. This defines how the contents of these columns is calculated when the lines are summarized.
Specifying Columns Dynamically
To specify the columns in the GROUP BY clause dynamically, use:
... GROUP BY (<itab>) ...
where <itab> is an internal table with line type C and maximum length 72 characters containing the column names <s 1 > <s 2 > .....
Example
DATA: CARRID TYPE SFLIGHT-CARRID,
      MINIMUM TYPE P DECIMALS 2,
      MAXIMUM TYPE P DECIMALS 2.
SELECT   CARRID MIN( PRICE ) MAX( PRICE )
INTO     (CARRID, MINIMUM, MAXIMUM)
FROM     SFLIGHT
GROUP BY CARRID.
WRITE: / CARRID, MINIMUM, MAXIMUM.
ENDSELECT.

PL/SQL 101 : Cursors and SQL Projection

PL/SQL 101 : Cursors and SQL Projection
This is not a question, it's a forum article, in reponse to the number of questions we get regarding a "dynamic number of columns" or "rows to columns"
There are two integral parts to an SQL Select statement that relate to what data is selected. One is Projection and the other is Selection:-
Selection is the one that we always recognise and use as it forms the WHERE clause of the select statement, and hence selects which rows of data are queried.
The other, SQL Projection is the one that is less understood, and the one that this article will help to explain.
In short, SQL Projection is the collective name for the columns that are Selected and returned from a query.
So what? Big deal eh? Why do we need to know this?
The reason for knowing this is that many people are not aware of when SQL projection comes into play when you issue a select statement. So let's take a basic query...
First create some test data...
create table proj_test as
select 1 as id, 1 as rn, 'Fred' as nm from dual union all
select 1,2,'Bloggs' from dual union all
select 2,1,'Scott' from dual union all
select 2,2,'Smith' from dual union all
select 3,1,'Jim' from dual union all
select 3,2,'Jones' from dual
... and now query that data...
SQL> select * from proj_test;
         ID         RN NM
         1          1 Fred
         1          2 Bloggs
         2          1 Scott
         2          2 Smith
         3          1 Jim
         3          2 Jones
6 rows selected.
OK, so what is that query actually doing?
To know that we need to consider that all queries are cursors and all cursors are processed in a set manner, roughly speaking...
1. The cursor is opened
2. The query is parsed
3. The query is described to know the projection (what columns are going to be returned, names, datatypes etc.)
4. Bind variables are bound in
5. The query is executed to apply the selection and identify the data to be retrieved
6. A row of data is fetched
7. The data values from the columns within that row are extracted into the known projection
8. Step 6 and 7 are repeated until there is no more data or another condition ceases the fetching
9. The cursor is closed
The purpose of the projection being determined is so that the internal processing of the cursor can allocate memory etc. ready to fetch the data into. We won't get to see that memory allocation happening easily, but we can see the same query being executed in these steps if we do it programatically using the dbms_sql package...

So, what's really the point in knowing when SQL Projection occurs in a query?
Well, we get many questions asking "How do I convert rows to columns?" (otherwise known as a pivot) or questions like "How can I get the data back from a dynamic query with different columns?"
Let's look at a regular pivot. We would normally do something like...
SQL> select id
2        ,max(decode(rn,1,nm)) as nm_1
3        ,max(decode(rn,2,nm)) as nm_2
4 from proj_test
5 group by id
6 /
        ID NM_1   NM_2
         1 Fred   Bloggs
         2 Scott Smith
         3 Jim    Jones
(or, in 11g, use the new PIVOT statement)
but many of these questioners don't understand it when they say their issue is that, they have an unknown number of rows and don't know how many columns it will have, and they are told that you can't do that in a single SQL statement. e.g.
SQL> insert into proj_test (id, rn, nm) values (1,3,'Freddy');
1 row created.
SQL> select id
2        ,max(decode(rn,1,nm)) as nm_1
3        ,max(decode(rn,2,nm)) as nm_2
4 from proj_test
5 group by id
6 /
        ID NM_1   NM_2
         1 Fred   Bloggs
         2 Scott Smith
         3 Jim    Jones
... it's not giving us this 3rd entry as a new column and we can only get that by writing the expected columns into the query, but then what if more columns are added after that etc.
If we look back at the steps of a cursor we see again that the description and projection of what columns are returned by a query happens before any data is fetched back.
Because of this, it's not possible to have the query return back a number of columns that are based on the data itself, as no data has been fetched at the point the projection is required.
So, what is the answer to getting an unknown number of columns in the output?
1) The most obvious answer is, don't use SQL to try and pivot your data. Pivoting of data is more of a reporting requirement and most reporting tools include the ability to pivot data either as part of the initial report generation or on-the-fly at the users request. The main point about using the reporting tools is that they query the data first and then the pivoting is simply a case of manipulating the display of those results, which can be dynamically determined by the reporting tool based on what data there is.
2) The other answer is to write dynamic SQL. Because you're not going to know the number of columns, this isn't just a simple case of building up a SQL query as a string and passing it to the EXECUTE IMMEDIATE command within PL/SQL, because you won't have a suitable structure to read the results back into as those structures must have a known number of variables for each of the columns at design time, before the data is know. As such, inside PL/SQL code, you would have to use the DBMS_SQL package, just like in the code above that showed the workings of a cursor, as the columns there are referenced by position rather than name, and you have to deal with each column seperately. What you do with each column is up to you... store them in an array/collection, process them as you get them, or whatever. They key thing though with doing this is that, just like the reporting tools, you would need to process the data first to determine what your SQL projection is, before you execute the query to fetch the data in the format you want e.g.
create or replace procedure dyn_pivot is
v_sql varchar2(32767);
-- cursor to find out the maximum number of projected columns required
-- by looking at the data
cursor cur_proj_test is
    select distinct rn
    from   proj_test
    order by rn;
begin
v_sql := 'select id';
for i in cur_proj_test
loop
    -- dynamically add to the projection for the query
    v_sql := v_sql||',max(decode(rn,'||i.rn||',nm)) as nm_'||i.rn;
end loop;
v_sql := v_sql||' from proj_test group by id order by id';
dbms_output.put_line('Dynamic SQL Statement:-'||chr(10)||v_sql||chr(10)||chr(10));
-- call our DBMS_SQL procedure to process the query with it's dynamic projection
process_cursor(v_sql);
end;

Of course there are other methods, using dynamically generated scripts etc. (see Re: 4. How do I convert rows to columns?), but the above simply demonstrates that:-
a) having a dynamic projection requires two passes of the data; one to dynamically generate the query and another to actually query the data,
b) it is not a good idea in most cases as it requires code to handle the results dynamically rather than being able to simply query directly into a known structure or variables, and
c) a simple SQL statement cannot have a dynamic projection.
Most importantly, dynamic queries prevent validation of your queries at the time your code is compiled, so the compiler can't check that the column names are correct or the tables names, or that the actual syntax of the generated query is correct. This only happens at run-time, and depending upon the complexity of your dynamic query, some problems may only be experienced under certain conditions. In effect you are writing queries that are harder to validate and could potentially have bugs in them that would are not apparent until they get to a run time environment. Dynamic queries can also introduce the possibility of SQL injection (a potential security risk), especially if a user is supplying a string value into the query from an interface.
To summarise:-
The projection of an SQL statement must be known by the SQL engine before any data is fetched, so don't expect SQL to magically create columns on-the-fly based on the data it's retrieving back; and, if you find yourself thinking of using dynamic SQL to get around it, just take a step back and see if what you are trying to achieve may be better done elsewhere, such as in a reporting tool or the user interface.

excellent article. However there is one thing which is slightly erroneous. You don't need a type to be declared in the database to fetch the data, but you do need to declare a type;
here is one of my unit test scripts that does just that.

getcardapplattrvalue_record getcardapplattrval_recordtype;
BEGIN
PN_CARDAPPL_ID := 1; --value must be supplied
v_Return := CCI_GETCUSTCARD.GETCARDAPPLATTRVALUE(
PN_CARDAPPL_ID => PN_CARDAPPL_ID
loop
fetch v_return
into getcardapplattrvalue_record;
dbms_output.put_line('Cardappl_id=>'||getcardapplattrvalue_record.cardappl_id);
dbms_output.put_line('Tag =>'||getcardapplattrvalue_record.tag);

exit when v_Return%NOTFOUND;

Use of Where and having clause

Hi all,
I always have a doubt about use of HAVING and WHERE clause,
suppose I have table T1 with only one column C1
CREATE TABLE T1
(C1 VARCHAR2(1) );
which having data by following INSERT scripts
INSERT INTO T1 VALUES('A');
INSERT INTO T1 VALUES('B');
INSERT INTO T1 VALUES('C');
INSERT INTO T1 VALUES('A');
INSERT INTO T1 VALUES('B');
INSERT INTO T1 VALUES('A');
Now I want result as follows
C1 ==== COUNT(C1)
==============
B ===== 2
A ===== 3
So out of query 1 and 2 which approach is right ?
1) SELECT C1,COUNT(C1) FROM T1
WHERE C1<>'C'
GROUP BY C1
ORDER BY C1 DESC;
2) SELECT C1,COUNT(C1) FROM T1
GROUP BY C1
HAVING C1<>'C'
ORDER BY C1 DESC;

In SQL, it's always best to filter data at the earliest moment possible.
In your example the WHERE clause would be that moment:
SQL> explain plan for
2 select c1,count(c1)
3 from t1
4 where c1 != 'C'
5 group by c1
6* order by c1 desc;
Explained.
SQL> select * from table(dbms_xplan.display);
PLAN_TABLE_OUTPUT
Plan hash value: 3946799371
| Id | Operation          | Name | Rows | Bytes |
|   0 | SELECT STATEMENT   |      |     5 |    10 |
|   1 | SORT GROUP BY     |      |     5 |    10 |
|* 2 |   TABLE ACCESS FULL| T1   |     5 |    10 |
Predicate Information (identified by operation id):
   2 - filter("C1"!='C')
18 rows selected.
SQL>As you can see the filter is applied during the scan of T1.
Whereas in the HAVING case:
SQL> explain plan for
2 select c1,count(c1)
3 from t1
4 group by c1
5 having c1 != 'C'
6* order by c1 desc;
Explained.

In general I would use as a guideline: if you are not using aggregate functions in your HAVING clause predicate, then move that predicate to the WHERE portion of your query.

Oracle 8i vs Oracle 9/10: Group by and order of returned rows

Hello people,
I've searched the forum for threads on this topic: the order of returned rows in queries which have a GROUP BY clause, and found out that Oracle states that GROUP BY clause does not guarantee that the order of returned rows will be the same every time nor the rows will be ordered someway. I've confirmed this information in the Oracle documentation for the GROUP BY clause for Oracle 9 and 10. But I couldn't find the same in the Oracle 8 documentation (SQL Reference), in which the GROUP BY clause section does not mention anything about the order of returned rows in queries which have a GROUP BY (except for something about using a GROUP BY and a HAVING clause together, which is not helpful in this situation).
Besides, I have an Oracle training book: "Introduction to Oracle: SQL and PL/SQL" for Oracle 8, where the GROUP BY clause is said to perform a default ordering, here is the text:
"By default, rows are sorted by ascending order of the columns included in the GROUP BY list. You can override this by using the ORDER BY clause".
So, I need to find out if Oracle 8 GROUP BY clause did some kind of sorting over the returned rows as it is said in the training book and if this behavior changed in Oracle 9. And more important: where to look for to find documentation about this change.
Thank you, guys, I really hope someone could help me with this.
Fer.

And this statement from Tom (taken from the link above) says more about why the sort (even when done because of group by) should not be relied upon:
<quote from="asktom link above">
and even when it does sort as a by product of its processing, the sort is a
BINARY SORT, not your sort (with your language and character set)
</quote>

Execution order - group by and order by

is there any execution order when we use group by and order by together in single query ?

BOL: "Logical Processing Order of the SELECT statement
The following steps show the logical processing order, or binding order, for a SELECT statement. This order determines when the objects defined in one step are made available to the clauses in subsequent steps. For example, if the query processor can bind to
(access) the tables or views defined in the FROM clause, these objects and their columns are made available to all subsequent steps. Conversely, because the SELECT clause is step 8, any column aliases or derived columns defined in that clause cannot be referenced
by preceding clauses. However, they can be referenced by subsequent clauses such as the ORDER BY clause. Note that the actual physical execution of the statement is determined by the query processor and the order may vary from this list.
1. FROM
2. ON
3. JOIN
4. WHERE
5. GROUP BY
6. WITH CUBE or WITH ROLLUP
7. HAVING
8. SELECT
9. DISTINCT
10. ORDER BY
11. TOP"

Answer an interesting question?
Create a wiki article about it!

How do I fix my 3gs after 6.1.3 update? It will no longer send / receive group messages and won't send pic text messages either.

Ever since I updated my 3gs (on ATT) to 6.1.3, it will no longer send or receive group texts, and it won't send picture messages
(though I seem to be able to receive picture texts). I've looked around on the boards, and here's what I've tried so far (to no avail):
1. Tried simply turning off / on
2. Tried hard reset
3. Tried having imessages off
4. Turned group messaging off / on (tried while it was off)
5. Turned off all messaging, turned phone off / on, turned all message settings back on
6. Reset network settings
Help! Argghh!!! I never had this much trouble when my previous phone was jailbroken! Here I am, trying to be good!

Thanks, Nick. Calling ATT is a last resort; it's a software issue, I'm sure, and I've also found other
people having the same issue, but none of the fixes work. I reset all my settings: nothing. I'm not sure what you mean by restrictions.
