Dynamic SQL in table vauled function or CLR

So I have a query that gives me some analysis on the values in a column, in a table. It reurns a small data set.
It gives me the max, min, stdev, avg and some other stats grouped by another column.
I wanted to create a table valued function from the query, so I could do the same analysis on any numeric column, in any table. I would just pass in the column name and the table name as paramters to my table-valued function and it would return the
data set. Then I could join to it and use in other queries.
I thought I would build my query using dynamic SQL and execute it within the function, but I got an error and learn that you can not use execute in a function.
I have never created a CLR function, would this be possible to do it this way? This would be a decent sized step for me, but am willing to learn if possible. Or does anyone know how to solve this problem?
Problem: Pass column name and table name into function and have it reurn a dataset. Use the dataset as a table in other queries, scripts or procedures like a table valued function.
Thanks,
Mike

Take a look into READ only table variable parameter
Create a user-defined data type with a single column.
Develop a procedure with a table variable as an input parameter.
Declare a table variable of the type of the user defined data type.
Loading 10 records into the table variable and pass the table
variable to the stored procedure.
create type tt_example AS TABLE
(spid int)
go
create procedure usp_example
@spids tt_example READONLY
AS
SELECT *
FROM @spids
GO
declare @spids tt_example
insert into @spids
select top 10 spid
from sys.sysprocesses
exec usp_example @spids=@spids

Dynamic SQL : passing table name as parameter

Hi
I have a SQL query (a store procedure ) that i want to convert to PLSQL
This is a part of my SQL query that i am trying to to find a solution for it, because i cant convert it to oracle :
DECLARE lookupTableRow CURSOR FOR
SELECT TableName FROM SYS_LookUpTable
OPEN lookupTableRow
FETCH NEXT FROM lookupTableRow INTO @tableName
WHILE @@FETCH_STATUS=0
BEGIN
SET @sql='SELECT * FROM '+@tableName
EXECUTE sp_executesql @sql
IF @counter=0
BEGIN
INSERT INTO T_TABLE_MAPPING VALUES('P_MAIN_METADATA', 'Table', @tableName)
END
ELSE
BEGIN
INSERT INTO T_TABLE_MAPPING VALUES('P_MAIN_METADATA', 'Table'+CONVERT(NVARCHAR(10),@counter), @tableName)
END
SET @counter=@counter+1
FETCH NEXT FROM lookupTableRow INTO @tableName
END
CLOSE lookupTableRow
DEALLOCATE lookupTableRow
As i understand i can't use ORACLE dynamic sql (execute immediate) when the table name is a parameter
Furthermore when i execute this dynamic query in my SQL store procedure each SELECT statement return me as a result the relevant table rows , those result are different in each loop .
So i cant do this too with ORACLE dynamic sql .
Please advice for any solution
* how can i use dynamic sql with table name as parameter ?
* how can i use a "dynamic" cursor, in order to be able to display the dynamic results ?
Thanks for the advice

I have a SQL query (a store procedure ) that i want to convert to PLSQL
I doesn't help when you use one term to mean another thing.
SQL is a language used in both Oracle and other products, such as Microsoft's SQL Server. I don't know much about SQL Server, but Oracle (at least) doesn't support stored procedures in SQL itself; they have to be coded in some other language, such as PL/SQL.
As i understand i can't use ORACLE dynamic sql (execute immediate) when the table name is a parameter
If the table name is a parameter (or only known at run-time for any reason), that's exactly the kind of situation where you MUST use dynamic SQL.
The number of columns that a query produces (and their datatypes) is fixed when you compile a query, whether that query is dynamic or not. If you have multiple queries, that produce result sets with different numbers of columns, then you can't combine them into a single query. The best you can do with one query is to add NULL columns to some of the queries so they all produce the same number of columns.
If you're just displaying the results, there might not be any reason to combine separate result sets. Just display one result set after another.
Whenever you have a question, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all the tables involved, and the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say what version of Oracle you're using (e.g. 11.2.0.2.0).

Want to create dynamic SQL with table join

I want to create a dynamic SQL query so that the user can enter any two table names on the selection screen and two field names that he wants to join. After which i should be able to dynamically generate the SQL (native or open) and show the result as report. I have already read the forum threads and know how to create dynamic SQL for single table, what i m struggling with is how to do inner join. I know i can use nested select but that will make the query very slow because i want to extend it to more than 2 tables later.
Will give points to useful answer for sure, thanks for reading.

Hi,
Following is a piece of code which I have used in my program.
DATA: ws_flds(72)   TYPE c.
DATA: ftab LIKE TABLE OF ws_flds.
ws_flds = 'rbukrs rprctr racct ryear '.
APPEND ws_flds TO ftab.
   SELECT (ftab)
    INTO CORRESPONDING FIELDS OF TABLE it_grp_glpca
    FROM glpca FOR ALL ENTRIES IN i_cert_item
    WHERE kokrs = c_kokrs
        AND rldnr = '8A'
        AND rrcty IN ('0','2')
        AND rvers = '000'
        AND rbukrs = i_cert_item-bukrs
        AND ryear = p_ryear
        AND rprctr = i_cert_item-prctr
        AND racct = i_cert_item-saknr
        AND ( poper BETWEEN '001' AND ws_poper )
        AND aufnr IN s_aufnr
        AND kostl IN s_kostl
        AND rfarea IN s_fkber
        AND rmvct IN s_rmvct
        AND sprctr IN s_sprctr
        AND ( racct BETWEEN c_low AND c_high ).
You can now pass your table name as (p_table) or append fieldnames to the internal table (ftab). if it is join then you can append this table like abukrs asaknr..etc.

How to migrate SQL serveer table-valued functions into Oracle 10g

hi ,
i'm trying to migrate from SQL server to Oracle. There are some Table_valued functions ( Function that returns table). while migrating using SQL Developer it uses cursor for every table query. is this is the only solution to migrate functions returning table? This tables contains more than LAKH of records? so if there any other solution on this please reply. the sample code is bellow.
CREATE function FU_AIG_S_GET_LOG
returns TABLE
as
RETURN
SELECT U_AIG.T_AIG_LOG.AIG_LOG_NB_IDLOG,

I don't think there's good work around over that. Mysql .sql file syntax is a little different from Oracle. Especially the DDLs.
Unless you are willing to blindly run the .sql file and fix the one failed manually.

This very simple: We cannot use dynamic SQL from used-defined functions written in T-SQL. This is because you are not permitted do anything in a UDF that could change the database state (as the UDF may be invoked as part of a query). Since you can
do anything from dynamic SQL, including updates, it is obvious why dynamic SQL is not permitted as per the microsoft..
In SQL 2005 and later, we could implement your function as a CLR function. Recall that all data access from the CLR is dynamic SQL. (here you are safe-guarded, so that if you perform an update operation from your function, you will get caught.) A word of warning
though: data access from scalar UDFs can often give performance problems and its not recommended too..

Question on Dynamic SQL Execution

Hi,
Our company is currently using Oracle 7 but will move to Oracle 8i soon. I am trying to execute a dynamic SQL statement in a function and it always error-out during execution. The SQL statement is NOT doing any update to a table. Its doing a select only. The function is being called during an execution of another dynamic SQL statement in a procedure. Here are examples of the code listing for the procedure and function:
CREATE OR REPLACE PROCEDURE TEST_PROC
lookup_cursor      integer;
ignore          integer;
VARvalue          number;
begin
lookup_cursor := DBMS_SQL.open_cursor;
DBMS_SQL.PARSE( lookup_cursor,
          'SELECT ' || TEST_FUNCTION || ' FROM DUAL,
          DBMS_SQL.NATIVE);
DBMS_SQL.DEFINE_COLUMN( lookup_cursor, 1, VARvalue);
ignore := DBMS_SQL.EXECUTE(lookup_cursor);
loop
     IF DBMS_SQL.FETCH_ROWS(lookup_cursor) > 0 THEN
     DBMS_SQL.COLUMN_VALUE(lookup_cursor, 1, VARvalue);
     ELSE
     EXIT;
     END IF;
END LOOP;
DBMS_SQL.CLOSE_CURSOR(lookup_cursor);
end TEST_PROC;
CREATE OR REPLACE PROCEDURE TEST_FUNCTION
lookup_cursor      integer;
ignore          integer;
VARvalue          number;
VARsql_string     VARCHAR2(200);
begin
lookup_cursor := DBMS_SQL.open_cursor;
VARsql_string := SOME GENERATED SQL STATEMENT;
DBMS_SQL.PARSE( lookup_cursor,
          VARsql_string,
          DBMS_SQL.NATIVE);
DBMS_SQL.DEFINE_COLUMN( lookup_cursor, 1, VARvalue);
ignore := DBMS_SQL.EXECUTE(lookup_cursor);
loop
     IF DBMS_SQL.FETCH_ROWS(lookup_cursor) > 0 THEN
     DBMS_SQL.COLUMN_VALUE(lookup_cursor, 1, VARvalue);
     ELSE
     EXIT;
     END IF;
END LOOP;
RETURN VARvalue;
end TEST_FUNCTION;
The error I received during execution of TEST_PROC is:
ORA-06571: Function TEST_FUNCTION does not guarantee not to update database
ORA-06512: at "SYS.DBMS_SYS_SQL", line 239
ORA-06512: at "SYS.DBMS_SQL", line 32
It may seem like the example procedure doesnt need to use a dynamic SQL execution to call TEST_FUNCTION but the actual code that I extracted from does.
Does Oracle 7 always treat the dynamic SQL command set as some kind of update statement? Is that a bug? I understand that the EXECUTE IMMEDIATE command in Oracle 8i will replace the old command set found in the above examples. Will using the new EXECUTE IMMEDIATE command in Oracle 8i solve this problem?
Thank you for any help,
Tony

In Oracle 7, for a function to be called from a select statement it has to follow the 'purity rule' that it does not modify any database table or package variable.
Probably you will have to use the compiler directive PRAGMA RESTRICT_REFERENCES (WNDS,WNPS) on your TEST_FUNCTION so that it can be called within a SQL statement.
This restriction is removed in Oracle 8i onwards.
Hope this solves your problem.

SQL CLR Table-Valued Function System.NullReferenceException

Good day.
I wrote a clr table-valued function that gets the data from the sharepoint list using the client model.
Sometimes I get exception (When I calling this function I get 90000 rows and then I get this exception...):
Msg 6260, Level 16, State 1, Line 1
An error occurred while getting new row from user defined Table Valued Function :
System.NullReferenceException: Object reference not set to an instance of an object. System.NullReferenceException: v at SDS.FillRow(Object obj, SqlInt32& month, SqlString& datePlanSalary, SqlString& dilerCode, SqlString& dilerName, SqlString&
model, SqlInt32& countSalary).
How can I fix this issue?
My Code:
public class SDS
[SqlFunction(SystemDataAccess = SystemDataAccessKind.Read, FillRowMethodName = "FillRow")]
public static IEnumerable SDSItems(SqlString url, SqlString listName)
ClientContext context = new ClientContext(url.ToString());
List list = context.Web.Lists.GetByTitle(listName.ToString());
CamlQuery query = new CamlQuery();
query.ViewXml = "<View/>";
ListItemCollection listItems = list.GetItems(query);
context.Load(list);
context.Load(listItems);
context.ExecuteQuery();
return listItems;
public static void FillRow(
object obj,
out SqlInt32 month,
out SqlString datePlanSalary,
out SqlString dilerCode,
out SqlString dilerName,
out SqlString model,
out SqlInt32 countSalary
item = (ListItem)obj;
month = Convert.ToInt32(item["_x041c__x0435__x0441__x044f__x04"]);
datePlanSalary = Convert.ToString(item["_x0414__x0430__x0442__x0430__x000"]);
dilerCode = Convert.ToString(item["_x041a__x043e__x0434__x0020__x04"]);
dilerName = Convert.ToString(item["_x041d__x0430__x0437__x0432__x04"]);
model = ((FieldLookupValue)item["_x041c__x043e__x0434__x0435__x04"]).LookupValue;
countSalary = Convert.ToInt32(item["_x041a__x043e__x043b__x0438__x04"]);

That's not a lot of information to go on, but...
Can you put a check in your FillRow method for a null object (or one of your fields being null) and put out diagnostic information? Or is it happening in the ListItemCollection iterator itself? (i.e. before it returns a row back to FillRow). If it's happening
in the iterator, perhaps you could subclass it and return diagnostics at that point.
I'm also wondering (if it actually always happen at row 90000) if you're hitting a limit in web service call, or iterator, or UDF code. Does the function ever return more than 90000 rows successfully?
Hope this helps, Bob

SQL from Table Column with Dynamic URL Problem

This is the SQL I'm attempting to save to a table column via the Object Browser;
select
"a"."PBR_BRIEF_ID" "Brief ID",
"a"."PROJECT_NUMBER" "Project",
"b"."DESCRIPTION" "Description",
"b"."ACTUAL_END_DATE" "Actual End",
"b"."RFS_DATE" "RFS",
"b"."LOCATION_CODE" "Location",
''||"b"."ESA_CODE"||'' "ESA",
"b"."PROJECT_USER_STATUS" "Status",
"b"."PROJECT_TRIGGER" "Trigger"
from
UPT1TRIAL.FUND_PLAN_BRIEF_LINK_CCR@NDSD "a",
UPT1INTEGRAL.INT_PROJECT_DATA@NDSD "b"
where
"a"."PBR_BRIEF_ID" = :P3_BRIEF_ID and
"a"."PROJECT_NUMBER" = "b"."PROJECT_DEFINITION_NUMBER"
The intesting bit is the following, where a URL is return behind a particular column;
''||"b"."ESA_CODE"||'' "ESA",
It's interesting because when I click on "Apply Changes" in the Object Browser, the text that appears in the column is as follows, i.e. with APP_ID and SESSION populated;
''||"b"."ESA_CODE"||'' "ESA",
Why would that happen??
The full SQL above is used in an application page with a SQL Query (PL/SQL function body returning SQL query). The basic SQL works OK but because of what the Object Browser is doing, the link does not.

Damian,
Use
& lt;
for your < tags and then the message will appear in the proper format.
If you are using dynamic sql to generate an url with APP_ID and SESSSION you could:
a) create page items (P1_APP_ID and P1_SESSION)
b) compute those page items to the actual APP_ID and SESSION_ID
c) use the value of those items while generating your dynamic sql (instead of APP_ID and SESSION)
Then, your links will show the right APP_ID and the right SESSION.

RFC WHICH CAN USE DYNAMIC SQL AS INPUT AND SHOW COMPLETE DATA FOR TABLE

Hi Expert,
I am trying to create a FM like RFC_READ_TABLE. In this table we put table name and the field name for which we write a query and option for query we get the out put only for that field in this case.
My requirement is very similar to this. But here i want to enter any table name and in option i want to write dynamic sql query for any filed of table then i want data based on this so that it will display the entire table entries.
Like TABNAMELIKE     EKKO
OTHERCON     bukrs_k = 3000.
Based on this selection it has to show the entire table fields.
To make this easy to understand i made a custom FM which are getting data from table or view and i select any field and put query it will show the result.
FUNCTION ZDYNSQL_EKKO_EKPO.
""Local Interface:
*" IMPORTING
*"     VALUE(ERNAMLIKE) TYPE CHAR15 OPTIONAL
*"     VALUE(OTHERCON) TYPE CHAR50 OPTIONAL
*" TABLES
*"      VALUE STRUCTURE V_EKKO_EKPO
*TABLES : V_EKKO_EKPO, EKKO, EKPO.
DATA: STR_WHERE TYPE TABLE OF EDPLINE.
DATA: STR_LINE TYPE EDPLINE.
*CONCATENATE 'EBELN LIKE''' EBELNLIKE '%''' INTO STR_LINE.
        CONCATENATE 'ERNAM LIKE ''' ERNAMLIKE '%''' INTO STR_LINE.
        IF OTHERCON <> '            '.
        CONCATENATE STR_LINE 'AND' OTHERCON '            ' INTO STR_LINE SEPARATED BY SPACE.
        ENDIF.
      APPEND STR_LINE TO STR_WHERE.
      SELECT * FROM V_EKKO_EKPO INTO CORRESPONDING FIELDS OF TABLE VALUE WHERE (STR_WHERE).
ENDFUNCTION.
Now here is sample code of exact requirement.
FUNCTION ZDYNSQL_TABLE_READ.
""Local Interface:
*" IMPORTING
*"     VALUE(TABNAMELIKE) TYPE DD02L-TABNAME
*"     VALUE(OTHERCON) TYPE CHAR80 OPTIONAL
*" TABLES
*"      VALUE STRUCTURE DD02L
DATA: STR_WHERE TYPE TABLE OF EDPLINE.
DATA: STR_LINE TYPE STRING.
        CONCATENATE 'TABNAME LIKE ''' TABNAMELIKE '%' 'DD02L' 'TABNAME' INTO STR_LINE.
        IF OTHERCON <> '            '.
        CONCATENATE STR_LINE 'AND' OTHERCON '            ' INTO STR_LINE SEPARATED BY SPACE.
        ENDIF.
      APPEND STR_LINE TO STR_WHERE.
      SELECT * FROM DD02L INTO CORRESPONDING FIELDS OF TABLE VALUE WHERE (STR_WHERE).
ENDFUNCTION.
In this i put table name as EKKO and put sql query as bukrs_k = 3000 it provide a short dump.
How can i solve this problem. Please provide some input or modification
Thanks And Regards
Ranjeet Singh

Hi Kris,
I tried to make sample using that link you provide to me. How can i declare Global Interface in FM and in import parameter references like "REFERENCE(I_INTERFACE_CHECK) DEFAULT SPACE".
Also it uses a function-pool.
Let me tell you about my exact requirement about FM.
I want in import parameter input as any SAP Table name like
TABNAME TYPE EKKO
OPTIONS TYPE CHAR80
I want my output to be stored in TABLES attributes as per the table name entered in import parameter. In import parameter Table name can be any one of SAP tables and Option based on that particular table. Like if i go with table EKKO and put OPTIONS as
ebelp = 4 then TABLES attributes Tab contains all the relevant data for input.
Is there any way with the help of that i can put my data into internal tables. I tried to put in TABLES as VALUE LIKE ANY but it shows that generic are not allowed. Can you provide some sample on this.
I also getting exceptions like CX_SY_DYNAMIC_OSQL_SEMANTICS, SAPSQL_INVALID_FIELDNAME.
Waiting for your valuable reply.
Thanks And Regards

Dynamic SQL and GRANT CREATE ANY TABLE

hi gurus,
i have a dynamic SQL in a procedure where a table will be created from an existing table without data.
strSQL:='create table ' || strTemp || ' as select * from ' || strArc || ' where 1=2';
execute immediate strSQL;
without GRANT CREATE ANY TABLE for the user, *"ORA-01031: insufficient privileges"* error during execution.
Is there a way to tackle this issue without providing GRANT CREATE ANY TABLE privilige?
many thanks,
Charles

The problem is not because of dynamic sql...It probably has something to do with dynamic SQL or, more accurately, dynamic SQL within a stored procedure.
From a SQL*Plus command prompt, you can create a table if your account has the CREATE TABLE privilege either granted directly to it or granted to a role that has been granted to your account. Most people probably have the CREATE TABLE privilege through a role (hopefully a custom "developer role" that has whatever privileges you grant to users that will own objects but potentially through the default RESOURCE role). That is not sufficient to create tables dynamically via a definer's rights stored procedure. Only privileges that are granted directly to the user, not those granted via a role, are visible in that case.
I expect that the DBAs are granting the CREATE ANY TABLE privilege directly to the account in question rather than through whatever role(s) are being used which is why that appears to solve the problem.

Dynamic SQL and use of aggregate functions

Hello Forum members,
I'm trying to create dynamic SQL in a function module and return the MAX value of a field.
I am passing in a parameter called CREATE_FIELD_NAME, and my SQL is
SELECT MAX(CREATE_FIELD_NAME) INTO (CREATE_DATE) FROM (TABLE_NAME).
I also tried:
SELECT MAX((CREATE_FIELD_NAME)) INTO (CREATE_DATE) FROM (TABLE_NAME).
But abap is not recognizing my variable as a variable in either case, but rather, as a field name.
Anyone know a way around this?
Thanks in advance,
Jeff
Here is my program:
FUNCTION ZJLSTEST4.
""Local Interface:
*" IMPORTING
*"     VALUE(TABLE_NAME) LIKE MAKT-MAKTX
*"     VALUE(CREATE_FIELD_NAME) LIKE MAKT-MAKTX
*"     VALUE(UPDATE_FIELD_NAME) LIKE MAKT-MAKTX
*" EXPORTING
*"     VALUE(MAX_DATE) LIKE SY-DATUM
DATA: CREATE_DATE LIKE MCHA-ERSDA VALUE '19000101',
      UPDATE_DATE LIKE MCHA-LAEDA VALUE '19000101'.
SELECT MAX(CREATE_FIELD_NAME) INTO (CREATE_DATE) FROM (TABLE_NAME).
ENDSELECT.
*SELECT MAX((UPDATE_FIELD_NAME)) INTO (UPDATE_DATE) FROM (TABLE_NAME).
*ENDSELECT.
IF CREATE_DATE > UPDATE_DATE.
   MAX_DATE = CREATE_DATE.
ELSE.
   MAX_DATE = UPDATE_DATE.
ENDIF.
IF MAX_DATE = '19000101'.
MAX_DATE = SY-DATUM.
ENDIF.
ENDFUNCTION.

Max is right, you need the spaces, as in my example.
You might like to try this:
data: l_CREATE_FIELD_NAME) LIKE MAKT-MAKTX,
      l_UPDATE_FIELD_NAME) LIKE MAKT-MAKTX.
DATA: CREATE_DATE LIKE MCHA-ERSDA VALUE '19000101',
UPDATE_DATE LIKE MCHA-LAEDA VALUE '19000101'.
concatenate 'MAX(' create_name ')' into l_create_name separated by space.
concatenate 'MAX(' update_name ')' into l_update_name separated by space.
SELECT SINGLE (l_CREATE_FIELD_NAME)
INTO CREATE_DATE FROM (table_name).
SELECT SINGLE (l_updATE_FIELD_NAME)
INTO updATE_DATE FROM (table_name).
IF CREATE_DATE > UPDATE_DATE.
MAX_DATE = CREATE_DATE.
ELSE.
MAX_DATE = UPDATE_DATE.
ENDIF.
IF MAX_DATE = '19000101'.
MAX_DATE = SY-DATUM.
ENDIF.
If it still fails please post the latest abap code for us to check.

Dynamic SQL Joining between tables and Primary keys being configured within master tables

Team , Thanks for your help in advance !
I'm looking out to code a dynamic SQL which should refer Master tables for table names and Primary keys and then Join for insertion into target tables .
EG:
INSERT INTO HUB.dbo.lp_order
SELECT *
FROM del.dbo.lp_order t1
where not exists ( select *
from hub.dbo.lp_order tw
where t1.order_id = t2.order_id )
SET @rows = @@ROWCOUNT
PRINT 'Table: lp_order; Inserted Records: '+ Cast(@rows AS VARCHAR)
-- Please note Databse names are going to remain the same but table names and join conditions on keys
-- should vary for each table(s) being configured in master tables
Sample of Master configuration tables with table info and PK Info :
Table Info
Table_info_ID   Table_Name
1       lp_order
7       lp__transition_record
Table_PK_Info
Table_PK_Info_ID   Table_info_ID   PK_Column_Name
2               1   order_id
8               7   transition_record_id
There can be more than one join condition for each table
Thanks you !

Hi Rajkumar,
It is glad to hear that you figured the question out by yourself.
There's a flaw with your while loop in your sample code, just in case you hadn't noticed that, please see below.
--In this case, it goes to infinite loop
DECLARE @T TABLE(ID INT)
INSERT INTO @T VALUES(1),(3),(2)
DECLARE @ID INT
SELECT @ID = MIN(ID) FROM @T
WHILE @ID IS NOT NULL
PRINT @ID
SELECT @ID =ID FROM @T WHERE ID > @ID
So a cursor would be the appropriate option in your case, please reference below.
DECLARE @Table_Info TABLE
Table_info_ID INT,
Table_Name VARCHAR(99)
INSERT INTO @Table_Info VALUES(1,'lp_order'),(7,'lp__transition_record');
DECLARE @Table_PK_Info TABLE
Table_PK_Info_ID INT,
Table_info_ID INT,
PK_Column_Name VARCHAR(99)
INSERT INTO @Table_PK_Info VALUES(2,1,'order_id'),(8,7,'transition_record_id'),(3,1,'order_id2')
DECLARE @SQL NVarchar(MAX),
@ID INT,
@Table_Name VARCHAR(20),
@whereCondition VARCHAR(99)
DECLARE cur_Tabel_Info CURSOR
FOR SELECT Table_info_ID,Table_Name FROM @Table_Info
OPEN cur_Tabel_Info
FETCH NEXT FROM cur_Tabel_Info
INTO @ID, @Table_Name
WHILE @@FETCH_STATUS = 0
BEGIN
SELECT @whereCondition =ISNULL(@whereCondition+' AND ','') +'t1.'+PK_Column_Name+'='+'t2.'+PK_Column_Name FROM @Table_PK_Info WHERE Table_info_ID=@ID
SET @SQL = 'INSERT INTO hub.dbo.'+@Table_Name+'
SELECT * FROM del.dbo.'+@Table_Name+' AS T1
WHERE NOT EXISTS (
SELECT *
FROM hub.dbo.'+@Table_Name+' AS T2
WHERE '+@whereCondition+')'
SELECT @SQL
--EXEC(@SQL)
SET @whereCondition = NULL
FETCH NEXT FROM cur_Tabel_Info
INTO @ID, @Table_Name
END
Supposing you had noticed and fixed the flaw, your answer sharing is always welcome.
If you have any question, feel free to let me know.

Dynamic sql to insert data in table

hi
I wish to insert 5 records in a table at runtime.
i.e the data should be entered at runtime.
I tried using a for loop but failed ..
I think it is possible thru dynamic sql ...
could someone help me out ..
regards
susmitha

If your database is 8 or above, you might want to try something like:
for i in 1..5 loop
execute immediate 'insert into table_name ' ||
'(your_field) values (your_value)';
end loop;
If your databasae is lower than 8, then you will have to use dbms_sql command instead. Hope this helps.

Using NVL function in Dynamic SQL

Hi ,
I have created a procedure using the Dynamic SqL and while using the NVL() getting the following error . ORA-00936: missing expression.
The query I have written as
SQL_Txt:=' INSERT INTO VF.tblCData (A, B, C, D, E, F,G,H,I,J)
     SELECT '||l_A||',
     '||l_B||',
     '||l_C||',
          '||l_D||',
          NULL ,
          '||L_F||',
          NVL('||Param1||',''''),
          NVL('||Param2||',''''),
          NVL('||Param3||',''''),
          NULL
          FROM '||ParamTbl1||' WHERE ' ;
and so on.
For Param1 I have data for one execution and Param2 and Param3 is null for that execution.
While executing the same I am getting below
INSERT INTO VF.tblCData (A, B, C, D, E, F,G,H,I,J)
SELECT 25,
     1,
     7,
          6,
          NULL ,
          5,
          NVL(PurchaseDate,''),
          NVL(,''),
          NVL(,''),
          NULL
          FROM xyz.PBuyer@pocdb WHERE
and error ORA-00936: missing expression is popping up for Param2 and Param3 NVL(,'')
Any suggestion to resolve this issue is highly appreciable.
Thanks
Sudipta

NVL(,''),Where's the first argument to NVL? That's the obvious problem. Empty strings are NULL in Oracle anyway, so just lose the NVL and insert the values...
