Build dynamic sql query

We would like to build our sql statements based on the parameters passed in. Does anyone know how to do this.
for example say something like
select business_name from business where
if input_user_id <> "" then
user_id = input_user_id;
else
user_manager_id = input_manager_id;
end if;

Hi Howard
Use a reference parameter in your query. Set the initial value of referece to "user_manager_id=input_manager_id". At runtime, the user may change the "WHERE" clause by entering an appropriate value in the parameter form.
* Create a query as: select business_name from business where &P_1
* The initial value of P_1 should be set to: user_manager_id=input_manager_id
* At runtime, the user will be prompted to enter values for P_1. The user may then specify "user_id=input_user_id" for P_1 or leave it alone.

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

To build dynamic SQL Query using some conditions: Pseudo code required

Hi,
I have a requirement where in i have to build a dynamic query based on one count.
Some details on requirement:
1) It's a Proc where i need to return some columns
2) There are some fix set of columns
3) Based on one Count column, i have to decide the rest of the columns.
Consider there is an employee who can work on 'N' number of assignments.
For a particular employee i have to return all the predefined details of assignments like:
1) Assignment Name
2) Assignmanet Id
3) Assignemnt Start Date
4) Assignment End Date
This 'N' can vary from employee to employee. Based on which i have to return my result set. For instance if employee has 3 assignemnts, i have to return Fix columns( employee info) + (3*4) columns. Similarly if the employee has 4 assignments, i will be returning Fix columns + (4*4) columns.
Certainly, the Employee ID is coming as an I/P parameter.
The source table is a vertical table having all details of the employee assignments.
Can anyone help me in coding this proc with the help of some pseudo code?

Do you mean you need something like this to be executed dynamically for some known n := max(count(assignment_id))

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();

dataTable = dataSet.Tables["livrosTitulo"];
dataGrid.DataContext = dataTable.DefaultView;

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.

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

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.

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:

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.

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

I am sure there is a better way to do this with dynamic sql. please help.
Thanks

Creating a dynamic SQL query builder class

I have a jobs table where each row contains information about jobs run on a machine. I have a web view of this database which shows different information and queries for this information are built using the following fields:
TYPE
TITLE
NODE
STATUS (an array of 4 different possible statuses)
TIMESTAMP
GUID (will be used when a view of a specific job (row in the table) is requested, no other search criteria needed when this view is required.)
All the criteria will be passed from the view layer into a search criteria object which is then passed to the DAO class which passes it to a BuildSQL class to use it to build the SQL.
There are many different "views" of the data which will result in many different combinations of criteria being passed down to the data access layer. (for example a status of failed and a timestamp resulting in all the jobs run in the last 2 hours)
As there are a number of different search criteria used in each query I'm having trouble designing the class to dynamically build the query. Are there any standard ways of doing this out there that could guide me?
At the moment I'm seeing this class as being a large combination of if statements and not really being very dynamic.
I was thinking maybe checking all the criteria to see if its null, if so ignore it straight away and then running through all the other criteria and appending one by one to the may SELECT which has already been created. Quite how i'd decided whether it would need an AND or OR before it I dont know.
Are there any standard proven ways to approach this because i've done a search here and on google and not really come back with much, so any advice would be great. I've got to say I'm pretty new to java and don't really have many bright ideas here!

Well my dear friend... I did something special for a business logic support to an web autocomplete component.
The criteria building was based on a custom variable into the SQL statement:
SELECT * FROM TABLE WHERE __MC__ AND (FIXED CRITERIA)
Where:
*FIXED CRITERIA: Is a fixed criteria that doesn't variate
*__MC__: Is a "custom variable" defined for me to make the replacement.
There are two main clases:
*SQLBuilder: It has many logic to build SQL Statements
*Multicriteria: It has the specific logic to insert into a SQL statement multiple criterias
// The SQLBuilder class
public class SQLBuilder {
    public static final String MC = "__MC__";
    static String buildMultiCriteria(String sql, Object[] params) throws Exception {
        for(int i=0; i<params.length; i++) {
            if(params[i] instanceof MultiCriteria) {
                sql = sql.replaceFirst("__MC__",
                        ((MultiCriteria)params).getCriteria());
params[i] = null;
return sql;
// The MultiCriteria class
public class MultiCriteria {
public static final int BEGINS = 0;
public static final int ENDS = 1;
public static final int CONTAINS = 2;
private String criteria = null;
public MultiCriteria(String[] fields, String value, int type) throws Exception {
String[] tokens = value.split(" ");
StringBuffer sb = new StringBuffer("(");
for(int i=0; i<fields.length; i++) {
for(int j=0; j<tokens.length; j++) {
if(tokens[j].length()>0) {
     sb.append(fields[i].toUpperCase());
     sb.append(" LIKE '");
     sb.append(toType(tokens[j], type));
     sb.append("'");
     if(j<tokens.length-1) sb.append(" OR ");
if(i<fields.length-1) sb.append(" OR ");
sb.append(")");
criteria = sb.toString();
public String getCriteria() {
return criteria;
private final String toType(String value, int type) throws Exception {
switch(type) {
     case BEGINS:
     value = value + "%";
     break;
     case ENDS:
     value = "%" + value;
     break;
     case CONTAINS:
     value = "%" + value + "%";
     break;
     default:
     throw new Exception("Undefined MutiCriteria type");
return value;
// I use the MultiCriteria this way
// criteria is a string introduced in a html input text
// The class splits the string by " " and ensemble multiple criterias
// for the given fields permuting them with the tokens resulting of the
// split
MultiCriteria mc = new MultiCriteria(
new String[] {"FIELD_01", "FIELD_02"},
     criteria,
     MultiCriteria.CONTAINS
I think this idea could help you.

Build a sql query fro different table and insert into a table

Hi I have a requirement ,
i have some table 1 table which holds rules which rules i have to apply on the sql query
2 table will hold table name and column name and transformation
with these help of 2 tables i want to build a sql quey and the sql query need to be insert into another table.

Hi Karthick,
I am not going to build Dynamic Data Model.
i already have table 1 contains rules let's say COUNT,
and another table contain source table name , column name , Target table name, Source Table name like that
so with the help of these 2 tables i want to build Sql query and going to insert into 3rd table.

Help needed in building a sql query

Hello,
I am using Oracle 10g db.
I have 3 tables table1 and table2 and table3
I am writing one sql query which is like
select table1.a a1,(select distinct b from table2,table3 where table2.id=table3.id and table1.id=table2.id) b1
from table1
Now the b1 value may give more then 1 values so when i am trying to execute the query its giving me error.
What i would like to have is if it gives returns more then 1 value then add that value as a new column means if b1 gives like abc and def as values.
Then i want the sql to return like
acolvalue abc def as a single row.
Is this possible to do?
Thanks

Hello,
The approach which i took is i wrote a function which gives me the b values , sseparated.
Then i am building a outer query considering the max of b so i just found there are max 10 values which one row is showing.
select b11,b12,b13,,,b10
from (
select table1.a a1,func(select distinct b from table2,table3 where table2.id=table3.id and table1.id=table2.id) b1
from table1)
but now i am facing problem like the value of b1 is a,b,c
i want to use the substr and instr function to get
a as b11
b as b12
c as b13
can anyone pls help me out to write a query? i am getting b11 but other values are somehow not coming.
for b11
i used
substr(b1,1,instr(b1,',',1,1)-1)
Thanks

How to build dynamic select query

Using the ZCO_SETTLE_CHK-REC_FIELD and DISTRIBUTION_RULE-KONTY write a dynamic select single query <table>-<field name> e.g. <COAS>- <AUART> on the <table> e.g. <COAS>. If the DISTRIBUTION_RULE-KONTY is u2018ORu2019, then use DISTRIBUTION_RULE-AUFNR value in the where clause of the query to fetch the ZCO_SETTLE_CHK-REC_FIELD value maintained in the <table>-<field name>. If DISTRIBUTION_RULE-KONTY = u2018KSu2019 or u2018PRu2019 use DISTRIBUTION_RULE-KOSTL or DISTRIBUTION_RULE- PS_PSP_PNR respectively in the where clause to fetch the values.
For above how we can build dynamic query

Hi,
Refer the below code which helps to design a dynamic where condition.
IF NOT p1 IS INITIAL.
CLEAR : lv_p1_condition.
CONCATENATE 'F1' ' = ' '''' p1 '''' INTO
lv_p1_condition.
ENDIF.
IF NOT p2 IS INITIAL.
CLEAR : lv_p2_condition.
CONCATENATE 'F2' ' = ' '''' p2 '''' INTO
lv_p2_condition.
ENDIF.
IF NOT p3 IS INITIAL.
CLEAR : lv_p3_condition.
CONCATENATE 'F3' ' = ' '''' p3 '''' INTO
lv_p3_condition.
ENDIF.
IF NOT lv_p1_condition IS INITIAL.
CONCATENATE lv_p1_condition lv_condition
INTO lv_condition SEPARATED BY space.
ENDIF.
IF NOT lv_p2_condition IS INITIAL.
IF lv_condition IS INITIAL.
CONCATENATE lv_p2_condition lv_condition
INTO lv_condition SEPARATED BY space.
ELSE.
CONCATENATE lv_condition 'AND' lv_p2_condition
INTO lv_condition SEPARATED BY space.
ENDIF.
ENDIF.
IF NOT lv_p3_condition IS INITIAL.
IF lv_condition IS INITIAL.
CONCATENATE lv_p3_condition lv_condition
INTO lv_condition SEPARATED BY space.
ELSE.
CONCATENATE lv_condition 'AND' lv_p3_condition
INTO lv_condition SEPARATED BY space.
ENDIF.
ENDIF.
SELECT * FROM link INTO wa
WHERE lv_condition .

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
            );
