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...

Dynamic SQL and Bulk Bind... Interesting Problem !!!

Hi Forum !!
I've got a very interesting problem involving Dynamic SQL and Bulk Bind. I really Hope you guys have some suggestions for me...
Table A contains a column named TX_FORMULA. There are many strings holding expressions like '.3 * 2 + 1.5' or '(3.4 + 2) / .3', all well formed numeric formulas. I want to calculate each formula, finding the number obtained as a result of each calculation.
I wrote something like this:
DECLARE
TYPE T_FormulasNum IS TABLE OF A.TX_FORMULA%TYPE
INDEX BY BINARY_INTEGER;
TYPE T_MontoIndicador IS TABLE OF A.MT_NUMBER%TYPE
INDEX BY BINARY_INTEGER;
V_FormulasNum T_FormulasNum;
V_MontoIndicador T_MontoIndicador;
BEGIN
SELECT DISTINCT CD_INDICADOR,
TX_FORMULA_NUMERICA
BULK COLLECT INTO V_CodIndicador, V_FormulasNum
FROM A;
FORALL i IN V_FormulasNum.FIRST..V_FormulasNum.LAST
EXECUTE IMMEDIATE
'BEGIN
:1 := TO_NUMBER(:2);
END;'
USING V_FormulasNum(i) RETURNING INTO V_MontoIndicador;
END;
But I'm getting the following messages:
ORA-06550: line 22, column 43:
PLS-00597: expression 'V_MONTOINDICADOR' in the INTO list is of wrong type
ORA-06550: line 18, column 5:
PL/SQL: Statement ignored
ORA-06550: line 18, column 5:
PLS-00435: DML statement without BULK In-BIND cannot be used inside FORALL
Any Idea to solve this problem ?
Thanks in Advance !!

Hallo,
many many errors...
1. You can use FORALL only in DML operators, in your case you must use simple FOR LOOP.
2. You can use bind variables only in DML- Statements. In other statements you have to use literals (hard parsing).
3. RETURNING INTO - Clause in appropriate , use instead of OUT variable.
4. Remark: FOR I IN FIRST..LAST is not fully correct: if you haven't results, you get EXCEPTION NO_DATA_FOUND. Use Instead of 1..tab.count
This code works.
DECLARE
TYPE T_FormulasNum IS TABLE OF VARCHAR2(255)
INDEX BY BINARY_INTEGER;
TYPE T_MontoIndicador IS TABLE OF NUMBER
INDEX BY BINARY_INTEGER;
V_FormulasNum T_FormulasNum;
V_MontoIndicador T_MontoIndicador;
BEGIN
SELECT DISTINCT CD_INDICATOR,
TX_FORMULA_NUMERICA
BULK COLLECT INTO V_MontoIndicador, V_FormulasNum
FROM A;
FOR i IN 1..V_FormulasNum.count
LOOP
EXECUTE IMMEDIATE
'BEGIN
:v_motto := TO_NUMBER('||v_formulasnum(i)||');
END;'
USING OUT V_MontoIndicador(i);
dbms_output.put_line(v_montoindicador(i));
END LOOP;
END;You have to read more about bulk- binding and dynamic sql.

Dynamic SQL and Sub Query

I want need to use dynamic SQL, and include a subquery in the where clause. However, I am getting a syntax error.
I have code that looks like this.
    SELECT (p_v_sqlobj_select)
        INTO CORRESPONDING FIELDS OF TABLE <matrix>
      FROM (p_v_sqlobj_from)
      WHERE (p_v_sqlobj_where).
and I pass it the following bold-faced SQL where clause (please ignore whether the statement makes sense and is the best way to do it - this is just to illustrate).   However, it returns an error.
select tcode from tstc where tcode in <b>( select min( tcode ) as min from tstc )</b>
Am I correct in concluding that I cannot pass complex statements, or have I just missed something?
Thanks for any help.

Hi,
Please try with order by clause in select statement and also use descending
      select * from (p_table)
               into corresponding fields of table <ptab>
              up to p_rows rows
              order by <fieldname> descending.

Dynamic SQL and Data with Single Quotes in it.

Hi There,
I have a problem in that I am using dynamic SQL and it happens that one of the columns does contain single quotes (') in it as part of the data. This causes the resultant dynamic SQL to get confused as the single quote that is part of the data is taken to mean end of sting, when in fact its part of the data. This leaves out a dangling single quote that was meant to enclose the string. Here is my dynamic SQL and the result of the parsed SQL that I have captured:
****Dynamic SQL*****
l_sql:='select NOTE_TEMPLATE_ID '||
'FROM TMP_NOTE_TEMPLATE_VALUES '||
'where TRIM(LEGACY_NOTE_CODE)='''||trim(fp_note_code)||''' '||
'and TRIM(DISPLAY_VALUE)='''||trim(fp_note_text)||''' ';
execute immediate l_sql INTO l_note_template_id;
Because the column DISPLAY_VALUE contains data with single quotes, the resultant SQL is:
******PARSED SQL************
select NOTE_TEMPLATE_ID
FROM TMP_NOTE_TEMPLATE_VALUES
where TRIM(LEGACY_NOTE_CODE)='INQ' and TRIM(DISPLAY_VALUE)='Cont'd'
And the problem lies with the single quote between teh characters t and d in the data field for DISPLAY_ITEM. How can I handle this?
Many thanks,

I have been reliably informed that if one doesn't enclose char/varchar2 data items in quotes, the right indices may not be usedI am into oracle for past 4 years and for the first time i am hearing this.
Your reliable source is just wrong. Bind variables are variables that store your value and which are used in SQL. They are the proper way to use values in your SQL. By default all variables in PL/SQL is bind variable.
When you can do some thing in just straight SQL just do it. Dynamic SQL does not make any sense to me here.
Thanks,
Karthick.

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.

Want to convert old movie files to put in Itunes.
What does "old movies" mean to you? File type, audio and/or video compression format(s)?
Can't upgrade QT player preinstalled, so downloaded QT Player 7 and purchased QTPlayer 7 Pro registration code. Can not get it to upgrade.
Did you follow the instructions found here?
If you have a fix, you can email me direct at [email protected]
To which fix do you refer? Activatng QT 7 Pro or converting the files? Even with QT 7 Pro activated you may need to modify your QT codec component configuration depending on the file type and compression formats used to encode your "old movies." There may be many different problems here with each having one or more "fixes." Please try to be more specific regarding your questions. Converting a muxed VOB MPEG2/AC3 file would be very different different from converting an AVI DivX5/MP3 file depending on which application you are attempting to use.

Dynamic SQL with cursor variables in pro*c

Please, what I need to do in order to be able
to do something like this:
EXEC SQL DECLARE :c CURSOR FOR :s;
In other words: I want to use variables
in cursor names.
Is it possible ? How ?
Thank you.

OK. Here is an example of a Dynamic SQL #4 program I wrote several years ago (It's still running in production). It is currently running on a Sun E10K with Oracle 8.1.5. This code is JUST the pro*c part of a program which uses IBM MQ Series. MQ passes this program a Select SQL statement (as well as other parameters) as an argument. The Pro*c code allocates the structures, parses, and fetches, and executes the statement. I realize that this will not be easy to read. There are SOME comments in the code. However, I realize that to read anyone elses code is a chore. When you add Dynamic #4 to the list, it becomes much more complicated. Anyway, you'll probably need to copy and paste the code to a text file. It will be easier to read.

Preparing Dynamic SQL statement for inserting in Pro*C

Hi Friends,
From quite some time i am struggling writing Dynamic SQL statement for dynamic insert and update in Pro*C.
Can somebody go through my code and suggest me the rigth way of doing.
Right now it throws an error saying " Error while updating ORA-00904: invalid column name "
Please help me.
Girish.
int main()
EXEC SQL BEGIN DECLARE SECTION;
char *uid ="scott/tiger";
static char sqlstmt[129];
struct /* DEPT record */
int dept_num;
char dept_name[15];
char location[14];
} dept_rec;
EXEC SQL END DECLARE SECTION;
EXEC SQL WHENEVER SQLERROR DO sql_error();
EXEC SQL CONNECT :uid;
dept_rec.dept_num = 50;
strcpy(dept_rec.dept_name,"ADMIN");
strcpy(dept_rec.location,"IN");
strcpy(sqlstmt,"UPDATE dept set DNAME = dept_rec.dept_name where DEPTNO = dept_rec.dept_num");
EXEC SQL EXECUTE IMMEDIATE:sqlstmt;
EXEC SQL COMMIT;
exit(0);
void sql_error()
printf("\nError while updating %s",sqlca.sqlerrm.sqlerrmc);
EXEC SQL ROLLBACK;
}

A bit rusty here but this is how I see it.
Think of it this way ..
all Oracle is going to see is:
UPDATE dept set DNAME = dept_rec.dept_name where DEPTNO = dept_rec.dept_num
Its NOT going to know what dept_rec.dept_name is or dept_rec.dept_num is ..
it doesnt go back and fill in those values.
You need something like
strcpy(sqlstmt,"UPDATE dept set DNAME = \"");
strcat(sqlstmt,dept_rec.dept_name);
strcat(sqlstmt,"\" where DEPTNO = ");
strcat(sqlstmt,dept_rec.dept_num);
printf(sqlsmt); # Just to be sure the update statement look right during testing.

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 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

> Relax damorgan, no need to be condescending. Of course I read the docs ..
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.
Remember that you came to this forum for forum members to help you. In order for us to do that, you need to help us understand
- your problem
- your environment
- what you have tried
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

Dynamic SQL and PL/SQL

I have the following scenario:
User Scott has two tables named USERINFO and EMP with the following description:
desc USERINFO
schema varchar2(30)
desc EMP
ename varchar2(30)
empno number(4)
User Blake has one table named EMP which looks like:
desc EMP
ename varchar2(30)
I want to write a function which would copy the values from Scott's EMP table to Blake's EMP table but I want to get the user Blake's name from USERINFO's schema column. I figured I'd have to use dynamic SQL but am getting some errors when I execute the function. It compiles fine. Below is the code
CREATE OR REPLACE FUNCTION CopyInfo()
RETURN VARCHAR2 AS
name VARCHAR22(30);
target_schema VARCHAR2(30);
ret_str CHAR := NULL;
BEGIN
SELECT schema INTO target_schema FROM version;
SELECT ename INTO name FROM scott.emp WHERE empno = 7902;
DECLARE
sqlStmt VARCHAR2(1028);
BEGIN
sqlStmt := 'INSERT INTO ' || target_schema || '.emp VALUES( name )';
execute SqlStmt ;
END;
ret_str := 't';
RETURN ret_str;
END CopyInfo
When I create the function, it comes back with -
Function created.
when I try to execute I get an error as shown below:
SQL>BEGIN
2 DBMS_OUTPUT.PUT_LINE( CopyInfo());
3 END;
4 /
ERROR at line 1:
ORA-00984: column not allowed here
ORA-06512: at "SCOTT.COPYINFO", line 13
ORA-06512: at line 2
Any idea, how to fix this ??? Thanks a lot....

Dynamic sql and ref cursors URGENT!!

Hi,
I'm using a long to build a dynamic sql statement. This is limited by about 32k. This is too short for my statement.
The query results in a ref cursor.
Does anyone have an idea to create larger statement or to couple ref cursors, so I can execute the statement a couple of times and as an result I still have one ref cursor.
Example:
/* Determine if project is main project, then select all subprojects */
for i in isMainProject loop
if i.belongstoprojectno is null then
for i in ProjectSubNumbers loop
if ProjectSubNumbers%rowcount=1 then
SqlStatement := InitialStatement || i.projectno;
else
SqlStatement := SqlStatement || PartialStatement || i.projectno;
end if;
end loop;
else
for i in ProjectNumber loop
if ProjectNumber%rowcount=1 then
SqlStatement := InitialStatement || i.projectno;
else
SqlStatement := SqlStatement || PartialStatement || i.projectno;
end if;
end loop;
end if;
end loop;
/* Open ref cursor */
open sql_output for SqlStatement;
Thanks in advance,

Example for 'dynamic' ref cursor - dynamic WHERE
(note that Reports need 'static' ref cursor type
for building Report Layout):
1. Stored package
CREATE OR REPLACE PACKAGE report_dynamic IS
TYPE type_ref_cur_sta IS REF CURSOR RETURN dept%ROWTYPE; -- for Report Layout only
TYPE type_ref_cur_dyn IS REF CURSOR;
FUNCTION func_dyn (p_where VARCHAR2) RETURN type_ref_cur_dyn;
END;
CREATE OR REPLACE PACKAGE BODY report_dynamic IS
FUNCTION func_dyn (p_where VARCHAR2) RETURN type_ref_cur_dyn IS
ref_cur_dyn type_ref_cur_dyn;
BEGIN
OPEN ref_cur_dyn FOR
'SELECT * FROM dept WHERE ' | | NVL (p_where, '1 = 1');
RETURN ref_cur_dyn;
END;
END;
2. Query PL/SQL in Reports
function QR_1RefCurQuery return report_dynamic.type_ref_cur_sta is
begin
return report_dynamic.func_dyn (:p_where);
end;

Dynamic sql and block based on a stored procedure

Hi!
I'm triying to generate a block based on a stored procedure. I want the stored procedure to execute a dynamic sql, but I'm having getting the error "PLS-00455 cursor 'AULOCASLATE' cannot be used in dynamic SQL OPEN statement".
I have the following code:
CREATE OR REPLACE package pkg_f0015 is
type rClieInstSlate is record
(clie_id CMS_CLIENTS.ID%type
,client_nm varchar2(1000)
,cs_no CMS_CLIENTS.CS_NO%type
,dob CMS_CLIENT_NAMES.BIRTH_DT%type);
type tClieInstSlate is table of rClieInstSlate;
type uClieInstSlate is ref cursor return rClieInstSlate;
procedure prLocationSlateQry(
auLocaSlate in out uClieInstSlate, anCsNo in CMS_CLIENTS.CS_NO%type,
avClieNm in varchar2,
avSearchType in varchar2,
avLotyCd in CMS_LOCATION_TYPES.CD%type);
end pkg_f0015;
CREATE OR REPLACE PACKAGE BODY pkg_cms_f0015 is
procedure PRLocationSlateQry( auLocaSlate in out uClieInstSlate,
anCsNo in CMS_CLIENTS.CS_NO%type,
avClieNm in varchar2,
avSearchType in varchar2,
avLotyCd in CMS_LOCATION_TYPES.CD%type) IS
vSelect varchar2(5000);
vAddCond varchar2(1000);
vSupLevel varchar2(50);
begin
vSelect := 'select clie.ID,'||
' CLIENT_NAME,'||
' clie.CS_NO,'||
' clna.BIRTH_DT dob'
' from CMS_CLIENT_NAMES clna,'||
'CMS_CLIENTS clie'||
' where clna.CLIE_ID = clie.ID';
if avSearchType= 'C' then
vAddCond := ' and clie.CS_NO = nvl('||anCsNo||',clie.CS_NO)';
vSelect := vSelect || vAddCond;
open auLocaSlate for vSelect;
end if;
end PRLocationSlateQry;
end;
I wonder if what I want is possible

OK,
Now it works. Previously we had the parameter p_guid declared as RAW, which obviously is not any good. :)
