Select Statement -- Where Clause Execution Order

What is the order of execution of the "AND" and "OR" in the WHERE clause of a Select statement?
Are the "AND"'s executed from the top down, left to right? Is it the same for the "OR"'s execution?
Thanks for any help...

Not clear why you care. There is an order in which the optimizer parses the SQL (which may change from ver to ver), but this is a fairly quick operation. The order in which tables are visited and predicates evaluated is dependent on what the op[timizer does with the SQL.

Offset operation in select statements where clause

dear experts,
    if i use offset operation in select query , syntactically giving
    me a warning message.
    how to avoid warning message
    without using another internal table populated with only jtab+0(10).
   ex:
          select field1 field2
                    into table   itab
                    from ztable1
                    for all entries in jtab
                    where field = jtab+0(10).
thanks in advance.

No need to populate another internal table...
when populating jtab from database select ur field twice
structure for jtab..
types: begin of ty_jtab,
          field type ...
          field1 type char10,
        end of ty_jtab.
populate the field twice..
   select ...
             field
             field
into table jtab
Now u can use the field field1 in the next select
select field1 field2
into table itab
from ztable1
for all entries in jtab
where field = jtab-field1.

Is it possible to use LONG columns in WHERE clause or ORDER BY?

Is it possible to use LONG columns in WHERE clause or ORDER BY?

Hi,
LONG data type is deprecated, maybe could you change your column type to LOB ?
Nonetheless below is a workaround which may fit your needs if forced to use LONG.
It uses a function which returns you a CLOB. It allows you to use the converted "LONG" column in a WHERE clause.
Then if you want to order by you have to convert the CLOB to a VARCHAR using DBMS_LOB.SUBSTR.
SQL> CREATE TABLE my_table (id NUMBER, description LONG);
Table created.
SQL> INSERT INTO my_table VALUES (1, 'FIRST LONG');
1 row created.
SQL> INSERT INTO my_table VALUES (2, 'ANOTHER LONG');
1 row created.
SQL> COMMIT;
Commit complete.
SQL> CREATE TYPE my_type_row AS OBJECT (id INTEGER, description CLOB);
2 /

SQL> CREATE TYPE my_type_table AS TABLE OF my_type_row;

Where clause and order by to DAO classes

Hi
Is it ok(I mean design wise) to pass the 'where clause' conditions and order by clause as a parameter to the method of DAO class?

Well, I would suggest you write seperate methods in your dao , one to select data without the where clause and one to select data with the where clause thrown in. If you have different 'where' clauses for selecting different kinds of data, have that many dao methods. The dao methods being specific know exactly what is the data that's coming in.
Lets assume you have a list of purchase orders and each purchase order is indetified by a unique id called PURCHASE_ORDER_ID.
1. The following code would populate a purchase order's details given an id.
private statis final String QUERY_1 = "select * from PURCHASE_ORDERS where PURCHASE_ORDER_ID = ? ";
PurchaseOrderModel getPurchaseOrderData(long poId){
     //get a prepared statement from your connection
     PreparedStatement pst = conn.prepareStatement(QUERY_1);
     //set the poId passed as params to your query
     pst.setLong(1, poId);
     ResultSet rs = pst.executeQuery();
     if(rs.next()){
          //populate data into a model
     finally{
          //clean up resources
     return model;
}2. The following code would return a list of PurchaseOrderModel's whose shipping date falls between a set of dates selected by the user.
private statis final String QUERY_2 = "select * from PURCHASE_ORDERS where SHIPPING_DATE between ? and ? ";
PurchaseOrderModel getPurchaseOrdersBetweenDates(list bindValues){
     //get a prepared statement from your connection
     PreparedStatement pst = conn.prepareStatement(QUERY_1);
     //set the dates passed as params to your query
     //we know that the List ought to contain only 2 dates
     pst.setDate(1, (Date)bindValues.get(0));
     pst.setDate(2, (Date)bindValues.get(1));
     ResultSet rs = pst.executeQuery();
     if(rs.next()){
          //iterate and populate data into a model
          //add model to a list
     finally{
          //clean up resources
     return list;
     3. This is more interesting - the dao method searches a list of Purchase Orders starting with a set of specific words. The words themselves may be one or many. This means that the number of '?' in your prepared statement may be dynamic. Each element of the list is a String that contains the start substring of a purcahse order name. For example - the list may contain elements like ["a", "ab", "c", "gh"] and the dao method returns all purchase order starting with these names.
private statis final String QUERY_3 = "select * from PURCHASE_ORDERS where ";
PurchaseOrderModel getPurchaseOrderNameMatches(list bindValues){
     //construct the query dynamically
     StringBuffer query = new StringBuffer(QUERY_3);
     int count = 0;
     for(Iterator itr = bindValues.iterator(); itr.hasNext();;){
          String value = (String)itr.next();
          query.append ("name like 'value%' ");
          if (count != 0 and (count+1 != bindValues.length)){
               query.append(" or ");
          count ++;
     //get a prepared statement from your connection
     PreparedStatement pst = conn.prepareStatement(query.toString());
     ResultSet rs = pst.executeQuery();
     if(rs.next()){
          //iterate and populate data into a model
          //add model to a list
     finally{
          //clean up resources
     return list;
To sum up,
1. You need as many methods as you have different kinds of searches (one method for each kind of 'where' clause).
2. The ejb/business layer would examine the data and decide on which method to call.
3. Increases coding effort, but makes the code clean and readable. Each layer does it's job. Thus we dont have ejbs forming 'where' clauses and so on.
Having said that, it really is your decision - you should take into consideration the following factors -
1. How big is the project ? If its a huge codebase developed by many people, then segregate the responsibilities clearly in each layer as I have outlined. For a small scale project, you could go with your approach.
2. Whats the take on maintenance and future add-ons ? Do you see the codebase growing with time ?
3. Is your project a commercial one - is it a product that needs to be maintained or is it a one-off development - develop once and you are done with it.
4. What are the design considerations ? Is somebody going to audit code for quality ? Or is it a academic one ?
You should take into account all these before deciding to go one way or the other.
A general thumb rule should be that you should be convinced that your code readable (maintainable), scalable and efficient. Anything that you do towards these ends is good code/design despite what people/books/patterns say, IMO.

SELECT with WHERE clause for MSAccess from JDBC

Hi,
I am new user of MSAccess.I am getting exception: Invalid user type when i was trying the following code:
String name1=nameTextfield.getText().trim();
String query="SELECT ID from Suppliers WHERE name=name1;"
Statement stmt=con.createStatement();
ResultSet rs=stmt.executeQuery(query);
while(rs.next())
String id1=rs.getInt(1);
System.out.println(id1);
nameTextField is JTextField in my GUI.
ID id auto field in table Suppliers.
I am using MSAccess 97.
I came to know that the JDBC SQL queries will be different for Access.
Any body help me how to write SELECT statement?
Thanks in advance,
Sai Ram

name or ID might be reserved words in access. Either change the name of the column or put [] around them. Also, you ar looking for a record where fields name and name1 are equal. You probably don't have a name1 field.
String name1=nameTextfield.getText().trim();
String query="SELECT [ID] from Suppliers WHERE [name]='"+name1+"';"
Pay attention to the single and double quotes I have.

v_char type c.
len = strlen( v_name ).
clear:v_name1,v_name2,v_name_final,v_num,v_num1,v_num2.
v_num1 = len.
do len times.
v_num1 = v_num1 - 1.
v_char = v_name+v_num(1).
v_num2 = v_num.
v_num = v_num + 1.
if v_num1 is initial.
    clear:v_name1.
else.
    v_name1 = v_name+v_num(v_num1).
endif.
if v_num2 is not initial.
    v_name2 = v_name+0(v_num2).

Hi
Yes you can, but you should use the language in the selection on MAKT:
SELECT MARA~MATNR
MAKT~MAKTX
MCH1~CHARG
MCH1~VFDAT INTO CORRESPONDING FIELDS OF TABLE GT_MATERIALS
FROM MARA
INNER JOIN MAKT
ON MARAMATNR = MAKTMATNR
INNER JOIN MCH1
ON MAKTMATNR = MCH1MATNR
INNER JOIN MVKE
ON MVKEMATNR = MAKTMATNR
WHERE MARA~MTART = 'ZDRU'
AND MARA~LVORM = SPACE
<b> AND MAKT~MAKTG LIKE '%DISCONTINUE%'
AND MAKT~SPRAS = SY-LANGU "or EN</b>
AND MVKE~VKORG = 'PUSA'
AND MVKE~VTWEG = 'SPART'
AND MVKE~MVGR4 = 92
AND MCH1~CHARG IN S_CHARG.

Select avoiding where clause

Hello,
I am using JPA in my app and I am confused because of a select that is returning data as I didn't have anything in my where clause.
Select A (with problems):
Query q = em.createQuery(
" Select distinct p "+
" From Subgrupo sub,"+
" UsuarioSubgrupo usb," +
" Usuario u, "+
" Grupo g, "+
" Projeto p "+
" where "+
" sub.cdGrupo = g.cdGrupo and "+
" g.cdProje = p.cdProje and "+
" g.stAdmin = 1 and " +
" sub.cdSubgr = usb.cdSubgr and " +
" usb.cdUsuar = u.cdUsuar and " +
" u.cdUsuar = 1"
Select B (almost OK):
Query q = em.createQuery(
" Select p.dsProje "+ // the only difference
" From Subgrupo sub,"+
" UsuarioSubgrupo usb," +
" Usuario u, "+
" Grupo g, "+
" Projeto p "+
" where "+
" sub.cdGrupo = g.cdGrupo and "+
" g.cdProje = p.cdProje and "+
" g.stAdmin = 1 and " +
" sub.cdSubgr = usb.cdSubgr and " +
" usb.cdUsuar = u.cdUsuar and " +
" u.cdUsuar = 1"
In the second select, I've got the rows according with where clause and I cannot understand how the fact of selecting an objetc Projeto (p) (select A) can make such a "mess" avoiding the rules of the where clause.
Could someone give me a help about this problem?
I'll be glad with any help!!
[]'s
Alex
!_Let's share ideas_!

Hi,
The issue is I am getting differents results from selects A and B and both have the same where clause.
I have done this:
Query q = em.createQuery(
" SELECT NEW entity.Projeto (p.dsProje, p.cdProje) "+
" From Subgrupo sub, "+
" UsuarioSubgrupo usb," +
" Usuario u, "+
" Grupo g, "+
" Projeto p "+
" where sub.cdGrupo = g.cdGrupo "+
" and g.cdProje = p.cdProje "+
" and g.stAdmin = 1 "+
" and sub.cdSubgr = usb.cdSubgr "+
" and usb.cdUsuar = u.cdUsuar "+
" and u.cdUsuar = " + cdUsuar
I am getting what I need, but the reason why a simple select p does not work I don't know.
This select is not generate by TopLink.
Cheers!

PL/SQL: how to use in parameter in select sql where clause

Hi
in a procedure, I need to apply 'in parameter' in 'where clause' along with other table fields. Purpose is to create dynamic select querry with multiple conditions.
select count(*) from table xx
where y_code=2008 and v_type in ('SI', 'TI', 'DI') ;
my requirement is replace 'and v_type in ('SI', 'TI', 'DI')' with in parameter. pls note in paramter may contain null value.
Regards

... e.g. why on earth do you want to pass in a string to be appended to the WHERE clause of an SQL.I second that and I strongly advice NOT to do it. If you really want to do it, then come back and show us, how you would prevent SQL injection. This approach is too dangerous (and too complex) IMHO.
Do it straight forward as in the article of Tom Kyte (link in the post of BluShadow above)

Avoid repeating same logic in 'select' and 'where' clauses?

I'll preface by saying I'm self-taught and have only been fiddling with SQL for a couple of months, so forgive me if this is a dumb question. I have a query written to pull out customers who are configured to have their products stored at the wrong warehouse, according to the first 3 digits of the zip code. Here is an extremely simplified version of a query I'm trying to run:
select custno, custbuy_zip_cd, custbuy_prim_ship_loc_cd as Warehouse,
case when substr(custbuy_zip_cd,1,3) in ('839','848') then '20'
when substr(custbuy_zip_cd,1,3) in ('590','591') then '33'
end as StdWhse
from customers
where case when substr(custbuy_zip_cd,1,3) in ('839','848') then '20'
when substr(custbuy_zip_cd,1,3) in ('590','591') then '33'
end <> custbuy_prim_ship_loc_cd
or (case when substr(custbuy_zip_cd,1,3) in ('839','848') then '20'
when substr(custbuy_zip_cd,1,3) in ('590','591') then '33'
end is not null and custbuy_prim_ship_loc_cd is null)
Now, the query works, but it seems overly convoluted and feels like there must be a way to make it simpler and faster. I'm using the same 'case when' 3 times. Originally, I had thought I could use the aliases from the 'select' clause in the 'where' clause, which would simplify things:
select custno, custbuy_prim_ship_loc_cd as Warehouse,
case when substr(custbuy_zip_cd,1,3) in ('839','848') then '20'
when substr(custbuy_zip_cd,1,3) in ('590','591') then '33'
end as StdWhse
from customers
where StdWhse <> custbuy_prim_ship_loc_cd
or (StdWhse is not null and custbuy_prim_ship_loc_cd is null)
I then found out that that caused 'invalid identifier' errors. My first attempt at a solution was to use a subquery in the 'from' clause, but that ran the 'case when' on every single customer instead of the small subset, so it wound up taking much longer even though it looked neater. Any tips on how to clean up that first query to make it run faster?
this is Oracle 11i, I believe. As a side note, I don't have write access to the database.

Thanks for all the tips so far - still going through them. You all respond fast! Sorry about using double angle brackets for != and not using code tags, I'll make sure to format my posts properly going forward. I think the double angle brackets messed up the appearance of my original queries a little. Here's how I probably should have pasted my first query in my first post:
select custno, custbuy_zip_cd, custbuy_prim_ship_loc_cd as Warehouse,
    case when substr(custbuy_zip_cd,1,3) in ('839','848') then '20'
        when substr(custbuy_zip_cd,1,3) in ('590','591') then '33'
    end as StdWhse
from customers
where case when substr(custbuy_zip_cd,1,3) in ('839','848') then '20'
        when substr(custbuy_zip_cd,1,3) in ('590','591') then '33'
    end != custbuy_prim_ship_loc_cd
    or (case when substr(custbuy_zip_cd,1,3) in ('839','848') then '20'
        when substr(custbuy_zip_cd,1,3) in ('590','591') then '33'
    end is not null and custbuy_prim_ship_loc_cd is null)The almost unanimous opinion seems to be that I should use a subquery in one way or another, but the problem remains that the only significant logic to narrow down the results is the logic that matches the 'case when' results (which are what the warehouse number should be, based on the zip code) to the current warehouse number. Therefore, it seems like any subquery is going to return my entire list of 600k customers, and take a much longer time than my original (messy) query. At least it has in the test runs I created based on
Satyaki's and Peter's examples. The query based on my original example takes about 2.5 minutes, and the subquery examples take about 5+ even though they look cleaner.
to clarify what the query is trying to accomplish, I want it to pull any records where the warehouse number does not equal the correct warehouse number based on zip code (or if the warehouse number is null when it shouldn't be).
I'll try to create some sample data and sample results. Customers table:
custno   custbuy_zip_cd custbuy_prim_ship_loc_cd
1        59024           20
2        59024           33desired results:
custno   custbuy_zip_cd   warehouse   StdWhse
1        59024            20          33If I could create a table to hold the standard warehouses to join on, the whole thing would be much easier. The full version of the query really has hundreds of zip code prefixes and 5 different warehouses and each account has 4 alternate warehouses as well. However, I'm stuck with read only access so everything has to go right in the query. It wouldn't be the end of the world to just stick with my original query since it's not like it takes hours, and I'll only be running it weekly. I just wanted to make sure there wasn't some other solution that wasn't just cleaner but was also faster.

Dynamic page with multiple select in where clause

Hi,
I have a dynamic page and in the where-clause, i have a bind variable. In a report i use for instance
and rtrim((to_char(date_time5,'DAY'))) IN :v_day
That works ok in a report. But it does not work in a dynamic page.
what code is needed to work with a multiple select box on the customize screen for a dynamic page?
Thanks.

Hi.
I have a dynamic page, with a bind variable :v_day. On the customization screen the user can select one or more days of the week, or all days. I use this also in a report and then it works ok. In the where clause i use:
and rtrim((to_char(date_time,'DAY'))) IN :v_day
Date_time is a tablecolumn (date).
When i add this line in the select script from the dynamic page, i get error:

Mysql select statement where = works and LIKE fails

I am using Flash Builder 4. On the server side I use php and mysql. I created a php dataservice using FB4. My plan had been to allow users to enter a search term and query the database using a "LIKE" statement. FB4 created the php code that I simply modified changing the parameter name. The input parameter is a string.
public function getT_caseByID($searchTerm) {
$stmt = mysqli_prepare($this->connection, "SELECT * FROM $this->tablename WHERE (title = ?)");
$this->throwExceptionOnError();
mysqli_stmt_bind_param($stmt, 'i', $searchTerm);
$this->throwExceptionOnError();
mysqli_stmt_execute($stmt);
$this->throwExceptionOnError();
mysqli_stmt_bind_result($stmt, $row->idt_case, $row->title, $row->id_author, $row->comments);
if(mysqli_stmt_fetch($stmt)) {
      return $row;
} else {
      return null;
A look at FB4 shows this code returns data.
This code works fine but if I make the below change it fails, even when I use the wildcard %. the only change is "=" to "LIKE".
public function getT_caseByID($searchTerm) {
$stmt = mysqli_prepare($this->connection, "SELECT * FROM $this->tablename WHERE (title LIKE ?)");
$this->throwExceptionOnError();
mysqli_stmt_bind_param($stmt, 'i', $searchTerm);
$this->throwExceptionOnError();
mysqli_stmt_execute($stmt);
$this->throwExceptionOnError();
mysqli_stmt_bind_result($stmt, $row->idt_case, $row->title, $row->id_author, $row->comments);
if(mysqli_stmt_fetch($stmt)) {
     return $row;
} else {
     return null;
A look into FB4 shows "void".
Any help would be appreciated. I am using localhost on Apache Server on a development computer with Windows XP.

Error:The Field "NAME" is a long string , so it cannot be used in WHERE, ON or HAVING conditions.

Hi Vara.
Select will not work if you are trying to search based on the name field as in the table CFX_COL it has data type String which basically is not content but a reference to a storage area and internally it is stored in a different format not searchable. Even , if you try to find the number of entries in the table you can not put any value in this field as it will not be available for input as it doesn't contain any value.
STRING: Character string with variable length This data type can only be used in types (data elements, structures, table types) and domains. In the Dictionary a length can be specified for this type (at least 256 characters). It may be used in database tables, however, only with restrictions. For a description of them refer to the documentation of the ABAP statement 'STRING' . In ABAP, this type is implemented as a reference to a storage area of variable size. As default for the output length 132 characters are proposed. You cannot attach search helps to components of this type.

Select statements where we have to write in crm 7.0

hi

where we have to write the code as a crm technical consultant
at which level genil or bol .if we write can u plz let me knw with clear answer.

Subhani,
Writing queries in CRM is always tricky. The question you have asked is very general, still i will try my hands on it for the larger benefit of the community.
One should avoid writing queries on UI layer - As a general practice writing queries on UI is not appreciated because it hampers performance to a large extent.
Use of standard FM instead of queries - There are several standard FM provided by SAP which serves most of the purpose for which queries may have to be written, they are written in a way so as to optimize the DB connect.
BOL/GenIL - Incase the interaction with the DB table is very frequent, Query must be written in BOL/GenIL layer, this is done in order to have a steady framework and avoid frequent DB connect.
If you have any specific query, feel free to post it but be more elaborative so that community members can help.

Harshit Kumar
