Ibatis like api to generate dynamic sql query

I use hibernate for persistance.Most of my queries are hibernate criteria queries , but some of them are sql queries, I have to generate dynamic queries which are very long , I have been using java to generate queries using lot of if else blocks , this makes debugging query very hard. I am looking something like ibatis where I can write my query in xml and can also provide conditions keep the and readable,but using ibatis I have to use ibatis to execute query, whihc I cannot do becasue I am using hibernate and I donto want multiple api for persistance , what I need is some like ibatis which can generate dynamic queries please suggest me what other use , how to writwe readable dynamic queries ?

Expected result :
I have two test case here with dealerID1 and dealerID 2
Result for DealerID1
Result needed for DealerID2:
the levels for dealers might change (Dealer1 has 4 levels, and Dealer 2 has 6 levels) so i need to create an dynamic sql query which lists each node as separate columns depending on the levels.
I have hacked the query to give the result I need
select a.dealerid,a.node as Lvl1,b.node as lvl2,c.node as lvl3,d.node as lvl4
from #test2 a
join #test2 b on a.node=b.prntnode
join #test2 c on b.node=c.prntnode
join #test2 d on c.node=d.prntnode
where a.dealerid=1 and a.dealerlvl=2
select a.dealerid,a.node asLvl1,
b.node as lvl2,c.node as lvl3,d.node as lvl4,e.node as lvl5,f.node as lvl6--,a.dealerlvl,a.dealerid
from #test2 a
join #test2 b on a.node=b.prntnode
join #test2 c on b.node=c.prntnode
join #test2 d on c.node=d.prntnode
join #test2 e on d.node=e.prntnode
join #test2 f on e.node=f.prntnode
where a.dealerid=2 and a.dealerlvl=3
I am sure there is a better way to do this with dynamic sql. please help.

Flash chart with dynamic sql query does not display

Hi,
In my schema SIVOA I have a lot of tables declared like this :
CREATE TABLE "SIVOA"."EVV_xxxx"
   (     "CLEF_VAR" NUMBER(4,0),
     "DATE1" DATE,
     "VALEUR" NUMBER(16,8) Only the last part of the name changes "xxxx". For example E009, E019, etc....
I am making a chart page with report and want the user to select a name of a table and I will display using dynamic sql query, the table report and chart.
P184_ENAME is a select list returning the last part of the name of the table, fro example 'E009', 'E019', etc.
P8_CLEF_VAR is an item containing a value. This value is a key retrieved like this :SELECT CLEF_VAR
FROM SIVOA.SITE_ECHELLE
WHERE SITE = :P184_ENAMEI built a classic report using a sql dynamic function :DECLARE
x VARCHAR2 (4000);
BEGIN
x := 'SELECT NULL, DATE1, VALEUR FROM SIVOA.EVV_'
|| UPPER(:p184_ename)
|| ' WHERE CLEF_VAR = :p8_clef_var' ;
RETURN (x);
END;:p8_clef_var is an itme containing the value '4544'.
This works perfectly fine !
When I use this sql fucytion into a flash chart it does not work. I get this message "No data found".
I do not understand why a the report get a result and not the chart !
But if i hard-code the number of the CLEF_VAR instead of fetching it from :p8_clef_var I get a nice chart ! Go figure !DECLARE
x VARCHAR2 (4000);
BEGIN
x := 'SELECT NULL, DATE1, VALEUR FROM SIVOA.EVV_'
|| UPPER(:p184_ename)
|| ' WHERE CLEF_VAR = 4544 ' ;
RETURN (x);
I cannot stay with the key (CLEF_VAR) hard-coded unformtunately !
My question is how to get the chart displaying properly ??
Thank you for your kind answers.
Christian

Alex,
Using your request, with the classic report I get results (data), but I get the same message with the Flash chart : "No data found" ! I don't know how to investigate this. i tried many things but nothing works.
Christian
PS I tried this :
DECLARE
   X   VARCHAR2 (4000);
BEGIN
x := 'SELECT NULL, DATE1, ROUND(VALEUR,2) FROM SIVOA.EVV_'
      || UPPER (:p184_ename) ||
      ' WHERE CLEF_VAR = '
      || :p8_clef_var ||
      ' AND DATE1 BETWEEN TO_DATE ('''
||:P8_DATE_DEBUT||''', ''DD/MM/YYYY HH24:MI'') AND TO_DATE ('''
||:P8_DATE_FIN||''', ''DD/MM/YYYY HH24:MI'')'
RETURN (X);
END; But it does not work either. I could find that the SLQ syntax generated is good becaus I put it into an item which display the return done by the pls/sql.
What is sttange also with the classic report is that if I do click on next or previous to see another rows, I get the message "No data found". If I try to export the report I get an excel file with "No data fouid".
Does anybody already tried my "need" here ? i find strange thant I should not be the firs one trying to get a report an tables which name would be "dynamic".
Tahnk you.

Proxy to JDBC scenario need dynamic sql query for sender .

Hi Experts,
I am developing proxy to jdbc scenario. in this i need to pass dynamic sql query whre we are passing classical method like below.
while we are passing select stmt in constant and mapped with access field and key field mapped with key field.
MY requirement is like instead of passing select stmt in constant where i can generate dynamically and passed in one field and mapped with access field.

Hi Ravinder,
A simple UDF or use of graphical mapping functions in most cases should provide you everything you need to construct a dynamic SQL statement for your requirement.

Build dynamic SQL query in Database Adapter.

Hi All,
I have a requirement to build dynamic sql query at Database Adapter.
My BPEL process is getting search spec as input from siebel. I need to process this searchspec in BPEL and need to build the SQL query dynamically at Database Adapter to fetch the records from DB.
it goes like this....
1. Sieble Search Spec: city1 OR city2 OR city3 OR city4 .....
I need to build query as
select * from S_ADDR_PER where city like 'city1' OR city like 'city2' OR city like 'city3' OR city like 'city4' ......
2. Siebel Search spec: city1 AND country1 AND state1....
I need to build query as
Select * from S_ADDR_PER where city like 'city1' AND country like 'country1' AND state like 'state1' ....
3. Siebel Search spec: state
I need to build query as
select * from S_ADDR_PER where state like '%state%';
Is it feasible in Database Adapter? if its Yes.
Any guidelines to achieve this?
Thank you
Chandra

Build stored procedure from a dynamic SQL query

I have the following method, that receives a string from a textbox and creates a dynamic select command. Since I am using a dataSet I cannot execute a dynamic SQL query by calling a method of a strongly-typed dataset (.xsd). I have been told that the best
way to do this is to pass an array of values to the stored procedure.
But I have no clue how to build the stored procedure.
string[] allWords = txtSearch.Text.Split(new char[] { ' ' }, StringSplitOptions.RemoveEmptyEntries);
string sql = "SELECT Books.ISBN, Books.Title, Books.Tag, Books.Image, Books.photoType, Publishers.Name AS publisherName FROM Books INNER JOIN Publishers ON Books.codPublisher = Publishers.codPublisher WHERE ";
using (SqlCommand command = new SqlCommand())
for (int i = 0; i < allWords.Length; ++i)
if (i > 0)
sql += "OR ";
string paramName = "@param" + i.ToString();
sql += string.Format("(Books.Title LIKE {0}) ", paramName);
command.Parameters.AddWithValue(paramName, allWords[i] + "%");
command.CommandText = sql;
//execute the SQL query against the db...

After hours around this, I have came with this solution.
private SqlConnection sqlConn = new SqlConnection();
private System.Data.DataSet dataSet = new System.Data.DataSet();
private System.Data.DataTable dataTable;
private System.Data.DataRow dataRow;
private SqlCommand search(string searchParam, int searchOption)
SqlCommand command = new SqlCommand();
string sql;
string[] allWords = searchParam.Split(new char[] { ' ' }, StringSplitOptions.RemoveEmptyEntries);
if (searchOption == 1)
sql = "SELECT Livros.ISBN, Livros.Titulo, Livros.Tema, Livros.Resumo, Livros.Imagem, Livros.fotoTipo, Editoras.Nome AS nomeEditora FROM Livros INNER JOIN Editoras ON Livros.codEditora = Editoras.codEditora WHERE ";
else
sql = "SELECT Livros.ISBN, Livros.Titulo, Livros.Tema, Livros.Resumo, Livros.Imagem, Livros.fotoTipo, Editoras.Nome AS nomeEditora FROM Livros INNER JOIN livrosAutores ON Livros.ISBN = livrosAutores.ISBN INNER JOIN Autores ON livrosAutores.idAutor = Autores.idAutor INNER JOIN Editoras ON Livros.codEditora = Editoras.codEditora WHERE ";
using (command)
for (int i = 0; i < allWords.Length; ++i)
if (i > 0)
sql += "OR ";
if (searchOption == 1)
sql += string.Format("(Livros.Titulo LIKE '%{0}%') ", allWords[i]);
else
sql += string.Format("(Livros.Autor LIKE '%{0}%') ", allWords[i]);
command.CommandText = sql;
return command;
protected void Bind()
sqlConn.ConnectionString = Properties.Settings.Default.BibliotecaConnectionString;
string connectionString = sqlConn.ConnectionString.ToString();
SqlDataAdapter sqlDataAdapter = new SqlDataAdapter(search(searchText, searchOption).CommandText, connectionString);

SSRS - Stored procedure with Dynamic SQL Query

Am calling stored procedure in SSRS report. I have used Dynamic SQL query in stored procedure as I don't know the column name and column count. And I have used like below at end of the stored procedure "select * from ##temptable".
As I have used dynamic column, am not able to create report with this stored procedure. Can someone help me out to resolve this issue.
It will be highly appreciated if I get help.
Thanks

I have tried everything. But nothing has worked out.
If I get solution for below issue, it would be highly appreciated.

Hello,
I would suggest you post the complete error message to us for further investigation, if you preview the report before you deploy you may get a more detailed error that will help diagnose the source of the problem.
This issue is more related to SQL Server Reporting Services, it's more appropriate to discuss it in the forum below:

Best way to spool DYNAMIC SQL query to file from PL/SQL

Best way to spool DYNAMIC SQL query to file from PL/SQL [Package], not SqlPlus
I'm looking for suggestions on how to create an output file (fixed width and comma delimited) from a SELECT that is dynamically built. Basically, I've got some tables that are used to define the SELECT and to describe the output format. For instance, one table has the SELECT while another is used to defined the column "formats" (e.g., Column Order, Justification, FormatMask, Default value, min length, ...). The user has an app that they can use to customize the output...which leaving the gathering of the data untouched. I'm trying to keep this formatting and/or default logic out of the actual query. This lead me into a problem.
Example query :
SELECT CONTRACT_ID,PV_ID,START_DATE
FROM CONTRACT
WHERE CONTRACT_ID = <<value>>Customization Table:
CONTRACT_ID : 2,Numeric,Right
PV_ID : 1,Numeric,Mask(0000)
START_DATE : 3,Date,Mask(mm/dd/yyyy)The first value is the kicker (ColumnOrder) as well as the fact that the number of columns is dynamic. Technically, if I could use SqlPlus...then I could just use SPOOL. However, I'm not.
So basically, I'm trying to build a generic routine that can take a SQL string execute the SELECT and map the output using data from another table to a file.
Any suggestions?
Thanks,
Jason

You could build the select statement within PL/SQL and open it using a cursor variable. You could write it to a file using the package 'UTL_FILE'. If you want to display the output using SQL*Plus, you could have an out parameter as a ref cursor.

Dynamic SQL Query to Find Special Characters in Table columns

Hi,
I am new to OTN FORUMS.
I am trying to find the columnsi of a table which have special characters in them.
I am planning on using this query
select ' select INSTR('||column_name||', chr(0))
from '||table_name||'where INSTR('||column_name||', chr(0)) >0' from user_tab_columns
where table_name='Account'
and spool the output to run as a script.
Is this the right way or do u suggest any modifications to the query?
Thanks in advance.

Hi,
I think your basic approach is right. Since you can't hard-code the table- or column names into the query, you'll need dynamic SQL.
Instead SQL-from-SQL (that is, writing a pure SQL query, whose output is SQL code), you could do the whole job in PL/SQL, but I don't see any huge advantage either way.
When you say "Special character<b>s</b>", do you really mean "one given special character" (in this case, CHR(0))?
Will you ever want to search for multiple special characters at once?
What if table foo has a column bar, and in 1000 rows of foo, bar contains CHR (0). Do you want 1000 rows of output, each showing the exact position of the first CHR(0)? If the purpose is to look at theese rows later, shouldn't you include the primary key in the output? What if CHR(0) occurs 2 or more times in the same string?
If you'd rather have one row of output, that simply says that the column foo.bar sometimes contains a CHR(0), then you could do something like this:
SELECT     'foo',     'bar'
FROM     dual
WHERE     EXISTS (
            SELECT NULL
            FROM       foo
            WHERE       INSTR ( bar
                        , CHR (0)
                    ) > 0
            );

A challenging dynamic SQL query problem

hi All,
I have a very interesting problem at work:
We have this particular table defined as follows :
CREATE TABLE sales_data (
sales_id NUMBER,
sales_m01 NUMBER,
sales_m02 NUMBER,
sales_m03 NUMBER,
sales_m04 NUMBER,
sales_m05 NUMBER,
sales_m06 NUMBER,
sales_m07 NUMBER,
sales_m08 NUMBER,
sales_m09 NUMBER,
sales_m10 NUMBER,
sales_m11 NUMBER,
sales_m12 NUMBER,
sales_prior_yr NUMBER );
The columns 'sales_m01 ..... sales_m12' represents aggregated monthly sales, in which 'sales_m01' translates to 'sales for the month of january, january being the first month, 'sales_m02' sales for the month of february, and so on.
The problem I face is that we have a project which requires that a parameter be passed to a stored procedure which stands for the month number which is then used to build a SQL query with the following required field aggregations, which depends on the parameter passed :
Sample 1 : parameter input: 4
Dynamically-built SQL query should be :
SELECT
SUM(sales_m04) as CURRENT_SALES,
SUM(sales_m01+sales_m02+sales_m03+sales_m04) SALES_YTD
FROM
sales_data
WHERE
sales_id = '0599768';
Sample 2 : parameter input: 8
Dynamically-built SQL query should be :
SELECT
SUM(sales_m08) as CURRENT_SALES,
SUM(sales_m01+sales_m02+sales_m03+sales_m04+
sales_m05+sales_m06+sales_m07+sales_m08) SALES_YTD
FROM
sales_data
WHERE
sales_id = '0599768';
So in a sense, the contents of SUM(sales_m01 ....n) would vary depending on the parameter passed, which should be a number between 1 .. 12 which corresponds to a month, which in turn corresponds to an actual field range on the table itself. The resulting dynamic query should only aggregate those columns/fields in the table which falls within the range given by the input parameter and disregards all the remaining columns/fields.
Any solution is greatly appreciated.
Thanks.

Hi another simpler approach is using decode
try like this
SQL> CREATE TABLE sales_data (
2 sales_id NUMBER,
3 sales_m01 NUMBER,
4 sales_m02 NUMBER,
5 sales_m03 NUMBER,
6 sales_m04 NUMBER,
7 sales_m05 NUMBER,
8 sales_m06 NUMBER,
9 sales_m07 NUMBER,
10 sales_m08 NUMBER,
11 sales_m09 NUMBER,
12 sales_m10 NUMBER,
13 sales_m11 NUMBER,
14 sales_m12 NUMBER,
15 sales_prior_yr NUMBER );
Table created.
SQL> select * from sales_data;
SALES_ID SALES_M01 SALES_M02 SALES_M03 SALES_M04 SALES_M05 SALES_M06 SALES_M07 SALES_M08 SALES_M09 SALES_M10 SALES_M11 SALES_M12 SALES_PRIOR_YR

Dynamic SQL Query count

Hi,
I need to retieve the number of records that will be retrieved by a query as follows.
How can this be done?
Is there a method to do it using native dynamic sql (open .. for .. using ) instead of DBMS_SQL (Because Native is faster than dbms_SQL )?
The following block demostrates what I need to do where v_query will hold the query text.
declare
v_query varchar2(32000);
v_count number;
begin
select query_text into v_query from groups_table where id =1;
dbms_output.put_line('count = '||v_count);
end;
Thanks in Advance

Is there a way to use sql%rowcount to do something similar?
Afraid not
I mean if there is a way to get better performance in case of very large query. Like for example in oracle forms, when using Query --> count records it retrieves the nubmer of records that will be fetched.
I think you'll find forms simply does a select count(*) from the base table (adding and predicates where necessary).
What are you going to use it for? Maybe there is an alternative route you can take...

Dynamic sql query question

hi all,
i created a report that displays results based on this query initially.
select *
from EMP
where 1=1;
i'm using a SQL Query (PL/SQL Function Body Returning SQL Query).
i have search items in my page like empno, lastname, firstname, middle, email_address etc... when i place a value for lastname then in my query it should add AND LASTNAME = :P1_LASTNAME.
so the query returned should now have
select *
from EMP
where 1=1
and LASTNAME = :P1_LASTNAME;
is this possible?
i was thinking something like looping for all search items in the page (ie. text, popup lov, datetimepicker) then check whether the item is null or not... when not null then probably get the substring of the item name like (ie. substr(:P1_LASTNAME) and get only LASTNAME then add "=" then concat it with the item name. not sure if this is possible though.
thanks

hi denes,
thanks for the sample... i noticed that the sample hard codes additional conditions to be added to the sql query which is okay when the search criteria is less than 5-10... but i'm thinking if the search criteria will be like 15-30 fields or make all fields searchable, this might be uncomfortable.
what i was thinking is like loop thru all the items i.e.
declare
sql varchar2(4000) := 'select * from emp where 1=1';
begin
for i in (select * from all_items_in_apex) -- this is just an example.
loop
if i.value is not null then
sql := sql || ' and ' || i.column || '=' || i.value;
end if;
end loop;
end;
the only thing is that i don't know if there's a possible replacement for the clause (select * from all_items_in_apex).
sorry if i'm asking too much but this is how i normally do it in forms. the suggestion in the link you provided should be sufficient but i was just wondering if this idea is also possible.
thanks again.

Selection screen - search help with dynamic sql query

hey ,
is it possible to change the search help of the selection field ?
when i create the range table i put a data element :
create a range table that consists of this new data element
LT_RANGE_TABLE = WD_THIS->M_HANDLER->CREATE_RANGE_TABLE( I_TYPENAME = 'S_CARR_ID' ).
can i control the search help via the the data element or by other methods ?
i want that when the user press F4 the values that will show is the result of a sql query that i will write .
is it possible ?
thanks
ASA.

Hi,
yes it is possible...
This is my test code for say personal number select options...
lt_range_table = wd_this->m_handler->create_range_table(
i_typename = 'PERSNO' ).
add a new field to the selection
wd_this->m_handler->add_selection_field(
i_id = 'PERSNO'
I_VALUE_HELP_TYPE = if_wd_value_help_handler=>CO_PREFIX_SEARCHHELP
I_VALUE_HELP_ID = 'ZHELP_WDA_PERNR'   "this is the custom search help we need to create
I_NO_INTERVALS = abap_true
it_result = lt_range_table
i_read_only = read_only ).
do the following:
1) copy the std function module: F4IF_SHLP_EXIT....to ZF4IF_SHLP_EXIT_pernr (in my case i am testing for pernr so my fm
name is like that....obviously it can be anything you want...under the recommended naming convention)
2) look for "STEP SELECT"
STEP SELECT    (Select values)
3)write the code as follows:
"NOTE: this is my testing code...but you can build your logic on it....
IF CALLCONTROL-STEP = 'SELECT'.
types: begin of zpri_listing,
pernr type PERSNO,
end of zfund_listing.
DATA: lo_syuname TYPE sy-uname.
data itab type standard table of Zpri_LISTING.
data wa type zpri_listing.
    DATA : t_fields LIKE TABLE OF shlp_tab-fielddescr.
    DATA : w_fields LIKE LINE OF shlp_tab-fielddescr.
    DATA : l_fname TYPE dfies-lfieldname.
    IF lo_syuname <> sy-uname. "means we were here before and ITAB is filled...fm retains its data values...unless refresh happens
"this if condition make sure that we do not do this select all the time as long as the same user is logged in...
"a user can press f4 many times...you might want to enhance this logic a little bit more for performance
      lo_syuname = sy-uname.
))))))))))))))HERE DO YOUR SELECT(((((((((((((((((((((
select pernr from "sometable" into table itab.
    ENDIF.
    LOOP AT shlp_tab.
      LOOP AT shlp_tab-fielddescr INTO w_fields.
        l_fname = w_fields-fieldname.
        CALL FUNCTION 'F4UT_PARAMETER_RESULTS_PUT'
          EXPORTING
            parameter               = w_fields-fieldname
          OFF_SOURCE              = 0
          LEN_SOURCE              = 0
          VALUE                   =
           fieldname               = l_fname
          TABLES
            shlp_tab                = shlp_tab
            record_tab              = record_tab
            source_tab              = itab
          CHANGING
            shlp                    = shlp
            callcontrol             = callcontrol
         EXCEPTIONS
           parameter_unknown       = 1
           OTHERS                  = 2
      ENDLOOP.
    ENDLOOP.
    IF sy-subrc EQ 0.
      callcontrol-step = 'DISP'.
    ELSE.
      callcontrol-step = 'EXIT'.
    ENDIF.
    EXIT. "Don't process STEP DISP additionally in this call.
ENDIF.
4) save and activate this function module...
5) go to se11 and create "Elementary srch hlp"....
6) fill out all the necessary fields...i am assuming that you already know how to create the search helps...
look for this field: "Search help exit" and put your function name which you created in the above steps...
in this example i have: ZF4IF_SHLP_EXIT_pernr....
7) create and activate the search help....
hope this helps...i just tested this and it is working for me....
Thanks..

NVARCHAR (MAX) TO PRINT DYNAMIC SQL QUERY TO A SQL FILE

Hi
I have a requirement where i need to write an SP which would construct a huge query using dynamic SQL and save the Dynamic query to a file.
The Dynamic SQL Variable I am using as @NVARCHAR(MAX) but since the query being built is large (>4000 characters), I am not able to select it into a table. PRINT @SQL prints the whole query but SELECT @SQL prints only upto 4000 characterrs.
And I need to save this huge dynamix sql to a file using the SP.
Any thoughts as to how i can achieve this?
Rajiv

This is a know problem with dynamic SQL nvarchar(max) concatenation.
See below for correct assembly of large SQL strings:
CREATE table #temp(qry nvarchar(max));
declare @cmd nvarchar(max);
SELECT @cmd=CONCAT(CONVERT(nvarchar(max),N'SELECT '),
CONVERT(nvarchar(max),REPLICATE (N'A',4000)),
CONVERT(nvarchar(max),REPLICATE (N'A',4000)),
CONVERT(nvarchar(max),REPLICATE (N'A',4000)),
CONVERT(nvarchar(max),REPLICATE (N'A',4000)),
CONVERT(nvarchar(max),N'FROM SYS.TABLES'));
insert into #temp SELECT @cmd;
select * from #temp;
select len(qry), datalength(qry) from #temp;
-- 16022 32044
drop table #temp;
