How to have a dynamic sql query clause as a bind var ?

Hi Folks ,
I need to set up a bind variable something like so
i_name in varchar(10);
begin
select * from tablename where col1 == :i_name
end
any ideas ?

Hi,
Here's an example of using a bind variable in SQL*Plus:
SET     SERVEROUTPUT ON   SIZE 10000
VARIABLE     target_job     VARCHAR2 (10)
EXECUTE     :target_job := 'CLERK';
BEGIN
     FOR emp_rec IN     (
                         SELECT     ename
               ,     job
               FROM     scott.emp
               WHERE     job     = :target_job
     LOOP
          dbms_output.put_line (emp_rec.ename
                         || ', '
                         || emp_rec.job
     END LOOP;
END;
/What are you trying to do?

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.
"An error occurred during local report processing.
The definition of the repport 'Main Report' is invalid.
The report defintion is not valid. Details: The report definition has an invalid target namespace 'http://schemas.microsoft.com/sqlserver/reporting/2010/01/reportdefinition' which cannot be upgraded.
Thanks
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:
https://social.technet.microsoft.com/Forums/sqlserver/en-US/home?forum=sqlreportingservices
Don't forget to elaborate your issue with more detail.
For the manual column, it might be the calculated field in SSRS. Here is the article for your reference, please see:

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.

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.

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);
sqlDataAdapter.Fill(dataSet, "livrosTitulo");
dataTable = dataSet.Tables["livrosTitulo"];
dataGrid.DataContext = dataTable.DefaultView;

Need generic dynamic sql query to generate nodes depending on dealer levels

insert into #test2 values (2,2213,245213,6)
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.
Thanks

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

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.

Visual Web - How to 'setObject' for an SQL query with an IN ? clause

Hello, I am relatively new to visual web pack. I am stuck at writing the java code for passing parameters to the SQL query. In a normal scenario, where we need to check if some variable is present in a column (= ?), we would pass the parameter as :
setObject(1, whatevervalue);
How do we pass parameters if we need to check for more than one variable? The query editor in VWP has the option IN, which allows us to check for more than one match in a column. The IN clause is supposed to allow the format ('ex1', 'ex2' ...). I tried using an array as a parameter, like, setObject(1, somearray). It gives me a null exception. I even tried sending a variable in ('ex1', 'ex2' ...) format; doesn't like it either.
Any help is greatly appreciated.

Using CASE in a dynamic sql query

Hi,
I want to create a dynamic query using the CASE statement to replace the below 2 SQL statements:
+++++
select 'create or replace synonym '|| SYNONYM_NAME || ' for '||TABLE_OWNER||'.'||TABLE_NAME||'@'||SUBSTR(db_link,1,30)||' ;' FROM USER_SYNONYMS where db_link is not null;
select 'create or replace synonym '|| SYNONYM_NAME || ' for '||TABLE_OWNER||'.'||TABLE_NAME||' ;' FROM USER_SYNONYMS where db_link is null;
+++++
So that i have a single select query which will give the create synonym statements for all with/without db links
Using the CASE statement example like given below :
SELECT
FirstName, LastName,
Salary, DOB,
CASE Gender
WHEN 'M' THEN 'Male'
WHEN 'F' THEN 'Female'
END
FROM Employees
I am not getting how to write this CASE statement. Can someone guide me here?
Thanks,

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
allen

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.

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?

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 * from #temp;
select len(qry), datalength(qry) from #temp;
