Split dynamic sql

Hi All,
I hve a different Requirement, i'm creating a rfc which execute the sql which is given by the client side n these r long single dynamic sql.
MY work is to write a (dynamic)code which split this sql in different small sql acc to their join combinations.
Let's take a exmple suppose i hve a long sql like
SELECT MARCMATNR marcwerks FROM MARC INNER JOIN MARD ON MARDWERKS = MARCWERKS INNER JOIN MARA ON MARCMATNR = MARAMATNR AND MARDMATNR = MARAMATNR WHERE MARCWERKS ='1000' AND MARAMATKL = '001'.
which used three tables MARA,MRAC,MARD in diff join conditions then I hve to split these in three diff sql for MARA MARC & MARD that gives same result as first one.
So wht should be keep in mind to design that issue that these splits sql gives same result as gives single one.
Regards
Anuj

hi anuj,
i would suggest that you drive your selection from MARA, as the number of entries on MATKL would be lesser as compared to MARC and MARD and morevover MARA has an index on MATKL.
so the solution would be like, first select the required article from MARA on condition MATKL into an internal table, Then do a join on MARC and MARD and perform a selection on "for all entries" of articles in the above internal table (this would ensure that MARC and MARD have selection on primary index).
I am getting a fast result doing this on nearly 500000 articles, so i think this should work pretty well for you too.
let me know, the result after you do this.

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 System.Data.DataSet dataSet = new System.Data.DataSet();
private System.Data.DataTable dataTable;

Hi,
Sorry, I don't see what you're trying to do.
"Dynamic SQL" is really a mis-nomer. The number of tables and columns in a query, and their names, must be spelled out when the statement is compiled. There is nothing dynamic about it.
In dynamic SQL, a PL/SQL procedure or another query writes all or part of query just milliseconds before it is compiled, typically using data taken from tables or supplied by a user right then.
For example, consider this static query:
SELECT     a.col1, a.col2, b.col1, b.col7
FROM     table_1     a
,     table_2 b
WHERE     a.col1 = b.col1;Now, say the 1 in "table_1" and the 2 in "table_2" are variables, x and y, that you will want to look up from another table every time you run this query. You can make it dynamic like this:
sql_txt := 'SELECT a.col1, a.col2, b.col1, b.col7 '
     || 'FROM    table_' || TO_CHAR (x) || ' a '
     || ',       table_' || TO_CHAR (y) || ' b '
     || 'WHERE   a.col_1 = b.col1';Now let's make it really interesting. Say that instead of 2 tables, and 1 join condition, you''ll have n tables and n-1 join conditions, where n has to be computed at (actually a split second before) run-time. That is, if n=4, you might need to construct a static query with 4 tables and 3 join conditions, like this:
SELECT     a.col1, a.col2, b.col1, b.col7
FROM     table_1     a
,     table_2 b
,     table_12 c
,     table_2 d
WHERE     a.col1 = b.col1
AND     a.col1 = c.col1
AND     a.col1 = d.col1;You can do that using dynamic SQL, too.
Post an example of the static query you need to build, and describe what parts of it are dynamic, and how you get the values for those parts, and someone will help you write the dynamic SQL.

NULL and dynamic SQL

If table testrh2 has the following columns and data
col1 --> NULL
col2 --> 2
and table testrh has the following columsn and data
col1 --> NULL
How could I write a dynamic SQL statement to join on the nulls? I've written the following block as a starting point.
declare
cursor c1 is select col1 from isis.testrh;
lval varchar2(1000);
lval2 varchar2(1000);
begin
for r1 in c1 loop
lval := 'select col2 from isis.testrh2 where col1 = '||r1.col1;
execute immediate lval into lval2;
dbms_output.put_line(lval2);
end loop;
end;

You can't compare null values with '=' in Oracle SQL.
Null can only be compared with <column> is null .
You can see it when you try these two queries:
select * from dual where null is null; -- you will see one row
select * from dual where null=null; -- you will see no rowsThat's why you have to write something like
(<column1>=<column1> or (<column1> is null and <column2> is null))This should also work with null:
decode(<column1>,<column2>,1,0)=1By the way, why do you use dynamic sql?
lval := 'select col2 from isis.testrh2 where col1 = '||r1.col1;
I think you could replace your two lines ( lval:= ... AND execute immediate) by this:
begin
select col2
into lval
from isis.testrh2
where decode(col1,r1.col1,1,0)=1;
dbms_output.put_line('lval='||lval);
exception
when no_data_found then
dbms_output.put_line('no data found'); -- or whatever you want

How to rename C00n generic column names in a Dynamic SQL report

I have a an interface whereby the user can select 1 to 60 (upper limit) columns out of 90 possible columns (using a shuttle) from one table before running a report.
To construct the SQL that will eventually execute, I'm using a "PLSQL function body returning SQL query" with dynamic SQL. The only problem is that I have to use "Generic Column Names" option to be able to compile the code and end up with c001 to c060 as the column names.
How can I use the names of the selected columns as the report headings rather than c001, C002... etc?
I do not know beforehand which columns, or how many columns or the order of the selected columns.
I know Denes K has a demo called Pick Columns but I can't access his code. I have a hunch though that he may be just using conditions to hide/show the apropriate columns.
thanks in advance
PaulP

Hi Paul
I would change the Heading Type in the Report Details screen to PLSQL and use the shuttle item to return the column values. e.g.
RETURN :p1_shuttle;
I'm assuming the shuttle already has a colon separated list of the column headings in the correct order?
I hope that helps

Unique id in dynamic sql

hi all,
I am using oracle 10g version.
I have one table but i do not have any unique id to identify the row.
I want to have a unique id temporarily in my select statement (dynamic sql) in a stored procedure while fetching the results, so that i can return my results along with the unique id through the cursor.
Please help me...
Thanks in advance to all...

it depends if you have a more than one column that you can uniquely identify and put them together by concatenating you can have a unique id. or a rowid might help you to temporarily identify a row.

How to mention numbers in array while creating dynamic sql

Hi,
I am creating a dynamic sql and in that I am selecting some rows from the table and storing it into the array.
I am firing this sql statement within trigger.
But i got the error:

I took the same sql statement (the one which was created dynamically) in the procedure and tried to run it but it gave me the same error.

I got a different error, but you need to initialise your nval_array and make sure it can hold three values. The following should work:
declare
type NewValueArray is table of varchar2(4000);
nVal_Array NewValueArray := NewValueArray();
Begin
nval_array.extend(3);
Select col1, col2, col3
into nVal_Array(1), nVal_Array(2), nVal_Array(3)
from tab1
where rowid = 'AAAGJZAAGAAAAAWAAV';

Dynamic sql and cursors

We are running an oracle sql procedure that uses a LOT of dynamic sql. We are using a 3rd party package (SQR) as a sort of shell to run the sql procedure. The 3rd party package passes to us an oracle error. This error says, in effect, that there are no inactive database cursors available and that the sql program is too large to process. We conclude from this that we must increase one or more of the cursor parameters in init.ora (v$parameters). Is this the correct assumption? If not, does anyone know what we can do? We'd prefer not to break up the sql procedure into smaller pieces.

increase the parameter for open cursors.
check, wether all cursors in your programs are closed in time, or if you are using ref cursors from front-ends (e.g. Java JDBC) that this front-ends close these ref cursors , too.
If you want to decrease the size of procedures get rid of comments, superfluos spaces, tabs, etc.
keep a commented version outside vor documentation purposes.
Hope thsi helps

Dynamic SQL and 255 bytes per line limit

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 IN CLAUSE from Pro C code

Hi Guys,
Tyring to embed sql in Pro C. Here I don't know in hand how many items will be there in the IN Clause of my dynamic sql. Tried this with a loop and then adding actual values to the stement and then executing it. This worked but as this hard coding makes it literal sql and hence hampers performance. Can any one help me with how to put bind variables where we don't know how many of them will be there in a dynamic sql.
Thanks,

Dynamic SQL supports user defined types, try passing a collection and using TABLE(CAST(collection)) in the SQL statement.
In the current approach (creating IN clause at runtime) keep in mind that in a IN clause you can put a maximum of 255 elements...
Max

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 and PL/SQL Gateway

This question is kind of out of curiosity...I had created a procedure that used some dynamic sql (execute immediate), and was trying to use it on pl/sql gateway. I kept getting page not found errors until I removed the execute immediate statement, and reverted to using static sql statements.
I am just curious, is dynamic sql not supported at all with pl/sql gateway?
Thanks
Kevin

Well, you're one of the few that actually read the docs.. And one of many that lacked to state any real technical details for forum members to understand the actual problem, the actual error, and what the environment is that this is happening in.

What PL/SQL Gateway do you refer to? Thus is an old term for an old product - today in Oracle there are two "gateways" into the PL/SQL engine via HTTP. Via Apache/mod_plsql and via the internal Java servlet web engine called EPG inside Oracle.
As for what the "Gateway" access to the PL/SQL engine via HTTP.. whether it supports EXECUTE IMMEDIATE or not is like asking if a car "supports" soft drinks or not (just because a human that may consume soft drinks acts as the driver of the car). Not sensible or relevant at all.
mod_plsql creates an Oracle session to the database instance, and executes a PL/SQL procedure in the database. This is no different from any other client connection to Oracle. Oracle has no clue that the client is mod_plsql and not TOAD or Java or VB or PHP or Perl or whatever else.
So how can this support or not support the EXECUTE IMMEDIATE command? Does PL/SQL support EXECUTE IMMEDIATE? Well duh...
Why do you get a generic 404? Because the PL/SQL call made by mod_plsql failed with an unhandled exception. mod_plsql gets that exception and now what? Was a valid HTP buffer created for it to stream to the web browser? If the buffer perhaps partially completed? All that mod_plsql knows is that it asked for a HTP buffer via that PL/SQL call and it got an exception in return.
A 404 HTTP error is the only reasonable and logical response for it to pass to the web browser in this case.
PS. to see why mod_plsql fail, refer to the access_log and error_log of that Apache httpd server
