Validate SQL Script

Hi,
I am working on a perl script to test if the sql script file prepared by the Dev team can be deployed to the DB without any issue or not. My intention is not to run the script but only to check if the script will run properly without any error at the time of actual deploy or not. Is there a way wherein I can mimic the execution of the script?
consider, I has a script file CreateTable.sql which contains CREATE TABLE statement. I dont want the table to be created by mimic actual run of this script against the database. How do I do that?
TIA

Not possible using PL/SQL. PL/SQL has a a very flexible DBMS_SQL cursor interface - that amongst other things allow you to parse a statement into a cursor. However, a parse call also automatically executes if the parsed cursor is a DDL. With DML, you can parse and not execute.
The only other way that comes to mind is using the EXPLAIN PLAN command in the SQL language. E.g.
SQL> explain plan
2 set statement_id = 'ddl.parse.1'
3 for create table testtab2 nologging as select * from user_objects;
Explained.
SQL> --//object not created
SQL> desc testtab2
ERROR:
ORA-04043: object testtab2 does not existThere could perhaps be a method using the OCI (Oracle Call Interface) to parse a DDL without executing it. Are you using Perl-DBI? In that case you may want to look at the OCI and how Perl-DBI exposes that - and whether a DDL can be parsed as cursor without executing it.

How to validate SQL scripts

Hi,
How to Validate SQL scripts?
I am having set of sql files i wish to run one by one if there is any error at one file i need to notify to the user.I have created Bat file in-order to execute in a sequence.how to validate in bat file

Use the SQL*Plus macro/command, WHENEVER SQLERROR EXIT <n>, to terminate a sql script when it hits an error - and have it return a specific exit code to the caller (o/s command line in this case). Note that exit codes are typically defined as a single byte in shells - which means it can only returns 0 to 255.
In the command line shell, check the exit code of the previous command - which would be command than ran sqlplus and the sql script. If the exit code is for example 255, then you know the WHENEVER SQLERROR command was executed. And then you cease processing sql scripts.
Simplistically (I do not do Windows), it will look as follows:
--// sql script
whenever sqlerror exit 255
... rest of the script
@echo off
rem command shell script
prompt executing script 1
sqlplus -s /nolog @sqlscript1.sql
if ERRORLEVEL 255 goto :ScriptFailed
prompt executing script 2
sqlplus -s /nolog @sqlscript2.sql
if ERRORLEVEL 255 goto :ScriptFailed
goto :Success

echo ...

IF Condition in a PL/SQL Script give a report error.

Hello, Im German and I hope you can unterstand my Question.
First, I work with the HTML DB Version 1.6.0.0.0.87 and the Oracle Version 9.2.0.6.
I create a SQL Report, where a PL/SQL Script return the SQL Statement for the Report. This is my source-code, I have short it...:
Declare
sql_str varchar(2000);
sql_str_select varchar(1000) :=' select dim_sparte ... ';
sql_str_from varchar(1000) := ' from faktentabelle,dim_sparte ';
sql_str_where varchar(1000):= ' where and faktentabelle.zeit_id = :POPUP_ZEIT ';
sql_str_groupby varchar(1000):= ' group by dim_sparte.name, faktentabelle.zeit_id ';
Begin
If ( (V('POPUP_NETZGEBIET') is not NULL) and (V('POPUP_NETZGEBIET') <>
'Alle Netzgebiete')) THEN
sql_str_select := sql_str_select || ' ,dim_organisationseinheit.netzgebiet_name ';
sql_str_from := sql_str_from || ' , dim_organisationseinheit ';
sql_str_where := sql_str_where || ' and faktentabelle ... and
dim_organisationseinheit.netzgebiet_name = :POPUP_NETZGEBIET';
sql_str_groupby := sql_str_groupby || ' , dim_orga .... ';
End IF;
sql_str:= sql_str_select || sql_str_from || sql_str_where || sql_str_groupby;
htp.print(sql_str);
Return sql_str;
End;
This Script include a IF-THEN condition. The Condition is true and the sql-String-Variables are updatet.
I can get the string with htp.print() and the Statement is OK.
The report get a Error report error: ORA-1403: no data found. If I copy the printet sql String in a new Report Region with SQL String, the Report is OK. When I write IF(true) instead of IF( Condition) the Report is OK, too.
I try ist with Varibalen V(name) and with :name. Its always the same problem. I cant use IF-THEN-Else Conditions in a Script.
Please help me and say me what is the problem???
Thanks,
Simona

Hi Simona,
In the sql region below the region source see that you have " Use Generic Column Names (parse query at runtime only)" check and not " Use Query-Specific Column Names and Validate Query".
This error you usually get when you have a mismatch in your report heading.

I have created a function. Now i need to test that whether it is returning the correct values or not.
For that, i have written anothe pl sql script and trying to call this function. Im passing all the IN parameters in that function. I assume here that OUT parameters will provide me the result. Im trying to display the OUT parameter one by one to see my result.

Don't look at the function, it might have errors but my primary concern is how to test this function. Once I start doing its testing then only i can understand any bugs(if any).
My pl sql is not so good. Im still learning. I don't understand IN and OUT parameters are.
I just know that IN parameters r those whick we pass in to the function wen we call it and OUT parameters are those through which we get the result.
Thanks in advance

Error in SQL script generated from OWB 10.1.0.4.0 Metadata Export Bridge

Hi... maybe i´m abusing this forum .. but .. when you have questions .. you have to look for answers
I use OWB 10.1.0.4 to buid some dimensions and one cube. I validate and generate this object and the result was successful.
I made the deployment and everithing goes OK !!!.
The problem appears when i want to generate metadata over this objects. I use the option Project > Metadata > Export > Gridge and use the option "Oracle 9i OLAP" like the product where i want to transfer the metadata .. and i got the SQL script without any errors. I suppose that i take the sql script i run it into SQL*plus ... so i do it.. and i got this errors:
declare
ERROR at line 1:
ORA-06501: PL/SQL: program error
ORA-06512: at line 119
ORA-06510: PL/SQL: unhandled user-defined exception
The same error for any dimension in script..
Any help .. will be fully valued for me ..
best regards
Lisandro.

But how did you identify that there are no runtime records in all_rt_audit_executions for your PL/SQL procedure?
I guess you tried to search by procedure name... (but what column you used for searching)
In my case all_rt_audit_executions and wb_rtv_audit_executions contains the same number of records, so they should be always in sync.

Validate SQL string before executing

I am attempting to find a way to validate an SQL script file before executing against a database. This is to allow any errors within the script to be identified and fixed before running against a pre-live / live database.
These scripts may contain both DDL and DML.
Is there any way to run the script and only have the changes visible to the current user, with all other database users unaffected until the changes have been checked (in a similar way to running an insert / update / delete without committing the changes)? Failing this, are there any tools to check the validity of the statements within an SQL script file?
Any help with these or alternative solutions would be much appreciated.
Cheers,
Steve

This is not sensible.
How can you test a DML that creates a table (that does not create the physical table) and then test a DDL that uses that table that was not created and of which no record exist?
The validity of a SQL statement (DML or DDL) depends on numerous factors, including the state of the database at that specific point in time that it is being run. You may test/check a DML that creates an index and it is fine.. until run on production where it times out as it cannot get a lock on the table in order to create the index.
Or there is insufficient free space in the tablespace to build the index. Or the index is build in parallel and one of the PQs fail because on an Oracle bug, resulting in the complete DDL failing.
Etc. Etc.
If the intention is to be able to test an upgrade/patch/install script for a production database for every single potential problem and error, and then have a 100% guaranteed success rate in running that on production.. er.. excuse me for a moment..
<mad laughter heard from outside>
Er.. okay. Back again.
This will need - no compromises and just for starters - the exact same h/w platform, o/s, Oracle s/w, and duplicated production database (cloned perhaps) as the test platform.
And if this is not possible or feasible then you should forget about having that script tested in such a fashion in order to have a 100% guarantee of a successful production deployment... and investigate the optimum method to test as far as possible, and build a comprehensive plan for change management and dealing with problems out of this upgrade, on production.

IF statement syntax in SQL script view

I need to include a "IF" condition in the "SELECT" section of my SQL script view.
I tried the following syntax's but I get the error 'Incorrect SQL syntax near 'IF'
1. IF(Revenue <> '0' AND Quantity <> '0', Revenue/Quantity, '0') AS Gross Price
2. IF(Revenue != '0' AND Quantity != '0', Revenue/Quantity, '0') AS Gross Price
3. IF(Revenue <> '0' AND Quantity <> '0' THEN Revenue/Quantity ELSE '0' END) AS Gross Price
4. IF(Revenue != '0' AND Quantity != '0' THEN Revenue/Quantity ELSE '0' END) AS Gross Price
My final SQL would read like follows:
SELECT field1, field2, IF(......) AS field3
FROM table1
Can anybody please help with the correct IF statement syntax to be used in the SQL script based view?

Hi Lakshmi,
below is the syntax for IF statement.
IF <bool_expr1> THEN
<then_stmts1>
ELSEIF <bool_expr2>
THEN <then_stmts2>
[ELSE <else_stmts3>]
END IF
eg :
BEGIN
DECLARE found INT := 1;
SELECT count(*) INTO found FROM books WHERE isbn = :v_isbn;
IF :found = 0 THEN
INSERT INTO books VALUES (:v_isbn, 'In-Memory Data Management', 1, 1, '2011', 42.75, 'EUR');
ELSE
UPDATE books SET price = 42.75 WHERE isbn =:v_isbn;
END IF;
END;

Pl/sql script needed - Urgent

Hi All,
I have one problem. I have to populate a table having rows more than 500000000 $ through PL/SQL.
For getting the idea...I have created one dummy table " T1 " with column " X " having 9 rows and
values in source are -
row 1 = 10
row 5 = 20
row 8 = 30
Other rows(2, 3, 4, 6, 7, 9) are null.
I want to carry fwd the values so the values in the same table will come like -
row 1, 2, 3, 4 = 10
row 5, 6 ,7 = 20
row 8,9 = 30
For resolving the problem i have written a procedure :
DECLARE
CURSOR cur_adb IS SELECT * FROM t1 ;
var cur_adb%rowtype ;
var1 number(10) ;
BEGIN
OPEN cur_adb ;
LOOP
FETCH cur_adb INTO var ;
DBMS_OUTPUT.PUT_LINE ( 'x=') ;
EXIT WHEN cur_adb%ROWCOUNT > 10 ;
If var is not null
then update t1
set x = var ;
var1 := VAR;
else update t1
set x = var1 ;
exit;
end if;
END LOOP;
CLOSE cur_adb ;
END ;
But it is giving me wrong result as it is fetching more rows at a time.
Pls. send me the correct Pl/SQL script as soon as possible.
Note: You can directaly send the procedure to [email protected] .
Thanks & Regs,
Ashish

Hello,
I got the solution by adding on more column in the source table :
source table : T1 -> x x_id
10 1
2
3
4
20 5
6
7
30 8
9
The procedure is :
SQL> DECLARE
2 CURSOR cur_adb IS SELECT x, x_id FROM t1 ;
3 var number(10) ;
4 var1 number(10) ;
5 var2 number(10) ;
6 BEGIN
7 OPEN cur_adb ;
8 LOOP
9 FETCH cur_adb INTO var , var2 ;
10 If var is not null
11 then var1 := VAR;
12 elsif var is null
13 then update t1
14 set x = var1
15 where x_id = var2;
16 end if;
17 DBMS_OUTPUT.PUT_LINE ('The value of x=' || var) ;
18 Exit when cur_adb%ROWCOUNT > 9 or cur_adb%NOTFOUND ;
19 END LOOP;

How can I convert a mysql sql script to a oracle sql script

Hi,
We have a bunch of tables with data running on a mysql server.
This should now be moved to an oracle 9 db.
are there any tools to convert the import script of a mysql db
to a format of the sql script that work for oracle ?
Thanks
Michael

Oracle has a tool called Migration Toolbench, which supports MySQL 3.22 and 3.23:
http://otn.oracle.com/tech/migration/workbench/content.html
On this same topic, I was wondering if anybody has tried migrating from PostgreSQL to Oracle 9i. The workbench doesn't seem to support it, and feeding a pg_dump file directly into SQL*Plus is not working.

How can I run a SQL script file...

How can I run a SQL script file from a location on my computer without providing the whole path?
Is there some way I can set a "Working folder" in SQL Plus??
Thanks!
Tom

You can create an environment variable called "SQLPATH" which is a list of directories that SQL*Plus will search for your .SQL
scripts.
I would like to use another directory than the oracle/bin...
How can I do this ??
Hello,
U can do this by this way:
Save odm_script.sql file to the default Oracle
directory i.e. Oracle-Home/bin and Run following command
through SQL Plus.
SQL>@Script_Name
I hope this will resolve ur problem.

Target Type=Database Instance
Host=myprodserver
Metric=Blocking Session Count
Blocking Session ID=SID: 522 Serial#: 5228
Timestamp=Mar 4, 2008 5:57:12 PM EST
Severity=Warning
Message=Session 522 is blocking 1 other sessions
Notification Rule Name=Testing Corrective actions
Notification Rule Owner=sysman
Clearly the sid, and serial # is contained within the alert Message field
what I want to write for the sql script is :
alter system kill session '%sid%,%serial_no%' immediate;
and have GC pass in the sid and serial_no to the script.
The "Target Properties" listed on the right of the Edit Corrective Action screen lists minimal details pertaining to the alert and certainly not the session sid, serial no.
Generically, is there any way to retrieve the values from an alert and use them in a corrective action script or job?
I've looked into getting the values from the mgmt$alert_history table, but I'm hoping that GC can pass the values to the sql script.
thanks in advance for your help.

Hi
You can implementing a procedure like this.
1. When a block session count alarms occurs, there is a column in the v$lock that you can examine.
#!/bin/ksh
#kill_block_session.sh
#first export your variables
export ORACLE_HOME=/oracle/product/10.2.0.3
export ORACLE_SID=SIDNAME
$ORACLE_HOME/bin/sqlplus "/ as sysdba" << EOF
execute immediate killed_blocks;
EOF
# end
The killed_blocks is a procedure:
create procedure
declare
v_sid varchar2(15);
v_serial varchar2(15);
-- now a sql query that retrieve the sid and serial
-- you can obtain these values from v$session and v$lock
select vs.sid,vs.serial into v_sid,v_serial
from v$session vs,v$lock vl
where vs.sid=vl.sid
and vl.block >0
-- After this, you execute a dbms_put line with these
-- values
But you understant that this response action is very dangerous, because its possible that you kill sessions that the blocking are transitient.
You must examine your enviroment and your application and establish the metric like UDM and not for only session blocking count.
You must to see:
- The type of block
- The ctime time in the v$lock for to understatn the amount of time to determine that the block is need killed.
- In my opinion you need a special UDM and deactivate the blocking sesion count
If you want help to create this UDM send me a mail to [email protected]
