A difficult dynamic SQL query problem

• Dynamic recovery for the dynamic sql query

  Hi all
  
  I want to create a query dynamically and to fetch it in a dynamic cursor record... The structure of the record should be the same as that of the query...
  Can you suggest any method to do this.
  
  for example
  
  OPEN < dynamic news > TO < dynamic stmt >;
  LOOP
  FETCH < dynamic news > < DYNAMIC rec >;
  ---
  END LOOP;
  CLOSE < dynamic news >;
  
  How to declare the rec here dynamic? I wouldn't have the columns in the query in advance either.
  
  Thank you

  Is not possible. What you describe is called four dynamic sql type. For this type of synamic SQL, you use the DBMS_SQL package.

• Dynamic SQL query in the DB adapter

  Hello
  I want to use the following custom SQL query in the DB adapter:
  
  SELECT EMP_ID, EMP_NAME, EMP_LOCATION FROM EMP WHERE EMP_ID IN (#iNPUT_PARAMETER)
  
  the problem I'm facing is that I don't know at the time of the development that EMP_ID how much will be passed to the process so that I can not use the input parameter specific number. I cannot use it IN the query within which statement I concatenate all the EMP_ID separated by comma and passed under INPUT_PARAMETER, but when running, he read the full concatenated string as a single string rather than identify them as a list of different: with comma separation. could someone help me in this case
  
  Thank you
  Sunil

  Use the following query with two parameters. Build the string with delimiter when running and pass this string and delimiter to query... (in this example, the input value would be the same for both Delimiter1 and Delimiter2.)

  Select * from EMP WHERE deptno IN (SELECT SUBSTR (STRING_TO_TOKENIZE, DECODE (LEVEL, 1, 1, INSTR (STRING_TO_TOKENIZE, SEPARATOR, 1, LEVEL-1) + 1), INSTR (STRING_TO_TOKENIZE, SEPARATOR, 1, LEVEL)-DECODE (LEVEL, 1, 1, INSTR (STRING_TO_TOKENIZE, SEPARATOR, 1, LEVEL-1) + 1)) FROM (SELECT #StringToTokenizer | #Delimiter1 AS STRING_TO_TOKENIZE, #Delimiter2 AS DELIMITER FROM DUAL) CONNECT BY INSTR (STRING_TO_TOKENIZE SEPARATOR) ((, 1, LEVEL) > 0)

• cache of SQL query problem

  I'm seeing the log file to manage the sql query sessions in the responses. I see that if we run the same report multiple times, the sql query is displayed only the first time. Second time if I run it is not displayed. If I make a new report with diff columns selected, it gives me the sql code then. Where can I put this option to display the sql query whenever I run a report, even if it's the same report executed several times. Is this caching problem?

  It should not... You have disabled the "Cache" on the physical layer for this table? If you go to the Advanced tab, is the option "ignore the cache Oracle BI" checked?

• SQL query problem - (internal has not managed to the outer query)

  Hi all:
  
  Here is my SQL query:

  Why am I the overall percentage of all Sites as opposed to each percentage calculation for each site. I've grouped by Rd. SITE, so I assume he would calculate the percentages for each site. What I've done wrong?
  
  Thank you for your help.

  It's what you're asking. Your subquery scalar to get the percentage is not restricted by the current site. Add columns to filter to restrict the values selected for the calculation

• Dynamic SQL query

  Hi all
  
  I have a procedure that takes as an input parameter v_emp_id which is of type varchar.
  
  emp_id are sent separated by commas to v_emp_id. Ex: v_emp_id = 7,2,1
  
  In my code I use a cursor for loop recover data from the table emp like this
  
  I'm in (select * from emp where emp_id in v_emp_id) loop
  -----
  end loop;
  
  It does not work. How do I use dynamic sql statements to retrieve data by using the CURSOR LOOP FOR only?
  
  Thanks in advance

  Not with dynamic sql statements. I suggest you use collections:

    8            dbms_output.put_line(v_rec.ename);

• Using CASE in a dynamic sql query

• Dynamic SQL query to get the unique value of list in a column

  I have two tables: tblWorkers and tblSkills. tblWorkers has a column, skills, which is populated by a field of multiple-checkbox with one or more skill_IDs of tblSkills, so each tblWorkers.Skills consists of a list of one or more comma-delimited values. For any Skill_ID, I need to generate a list of all workers with the appropriate skills, so I tried to do something in the direction of SELECT WorkerName FROM tblWorkers WHERE IN of skills (skills, #FORM. Skill_ID #)... or WHERE skills (ListFind (skills, #FORM. Skill_ID #))... etc.? My results (once I have had data type mismatches of the road) return all workers, not just those with the desired skills. There must be an easy way to do... How people with a little more experience CF/SQL I do this?

  > each tblWorkers.Skills consists of a list of one or more comma-delimited values

  This is your problem. You store a list of values that you want to access power/query separately in a single column. You will have to burst in a separate table.
  TblWorkers

  TblSkills

  TblWorkerSkills
  mapping table of many workers with skills.

  If you do not change your data model now, you will constantly be butting your head against that.

  Welcome to the forum.

  First read this:

  Emergency in online messages

  Second, it is always helpful to provide the following information:

  1. oracle version (SELECT * FROM V$ VERSION)
  2. examples of data in the form to CREATE / INSERT commands.
  3. expected results
  4 explanation of the expected results (alias "business logic")
  5. use.

   tags for #2 and #3. See FAQ (Link on top right side) for details.
  
  You have provided #3 and #4. However with no usable form of sample data forum members will often not respond as quickly as they could if you provided #2.
  
  I'm just wagering a guess here but what about this:
  

  SELECT ROW_ID
  USER_ID
  WKND_DT
  ETIQUETTEMOIS
  MAX (PROD_EFFORTS) AS PROD_EFFORTS
  MAX (UNPROD_EFFORTS) AS UNPROD_EFFORTS
  OF RISK_EFFORTS

  Thank you

  'Column 'dbo.easytoletproperty.propertylive' is invalid in the select list because it is not contained in the clause Group By or an aggregate function'

  Fix. You have used an aggregate function, then all other columns that are not part of an aggregate must be grouped together by using the group by clause.

• Dynamic PL SQL query

  Hello

  I want to run and store the results of a dynamic sql query in a strored procedure.

  I get the following variables of the user running: v_column_names, v_table_name, v_col, v_value

  The query will be like:

  v_query: = 'SELECT'. v_column_names | ' A ' | v_table_name | ' WHERE ' | v_col |' = ' | v_value;

  for example v_column_names: = 'ACCOUNT_NUM, SYSTEM_ID, ENTITY_ID ';

  v_table_name: = 'ACCOUNT '.

  v_col: = 'COUNTRY_CODE ';

  v_value: = "USA";

  Here is what I tried

  DECLARE

  v_column_names VARCHAR (200): = 'ENTITY_ID, SYSTEM_ID, ACCOUNT_NUM;

  v_table_name VARCHAR (200): = 'ACCOUNT '.

  v_col VARCHAR (200): = 'COUNTRY_CODE ';

  v_value VARCHAR (200): = "'USA"';

  TYPE column_record () IS RENDERING

  VARCHAR2 (200) C1: = null;

  C2 VARCHAR2 (200): = null;

  C3 VARCHAR2 (200): = null

  );

  TYPE st_table IS TABLE OF column_record INDEX DIRECTORY.

  pk_table st_table;

  NUMBER of v1: = 1;

  BEGIN

  v_select: = 'SELECT'. v_column_names | ' A ' | v_table_name | ' WHERE ' | v_col |' = ' | v_value;

  EXECUTE IMMEDIATE v_select COLLECT LOOSE pk_table.

  I'm IN 1.pk_table.count LOOP

  DBMS_OUTPUT. Put_line (pk_table (v1). (C1);

  DBMS_OUTPUT. Put_line (pk_table (v1). (C2);

  DBMS_OUTPUT. Put_line (pk_table (v1). (C3);

  v1: = v1 + 1;

  END LOOP;

  END;

  The number of column names in v_column_names is dynamic, so I need a way to store the results and then manipulate them.

  I look forward to your reply.

  EDIT: The real question:

  1. in the settings I have pass the table name and the value of the primary key of the row I want to delete.

  2. He then checks if this line is referenced anywhere, removes the reference, and then deletes the current line. This can go, until all the rows that are referenced are removed.

  The above code, I have provided a small part of the largest of stored procedure.

  Thank you all, I found the tips very helpful. I found a solution to my problem:

  Oracle - how to build queries DELETE in PL/SQL, based on the tables of the FK relations? -Stack overflow

  It generates all removal requests to remove a specific line.  Not what I wanted, but this does not solve my problem.

  The reason why is that I discovered that we do not use the ON DELETE CASCADE that we don't remove a record accidentally, I know we have an option to restore, but it is just in case something goes wrong.
