I have deployed an SSIS package which has a query that pulls data from oracle. The query has some variables in it and I wanted to see what variable were being inputted at run time. Is there a way maybe via sql profiler that I can capture the query that sql server is sending out to Oracle when the sql job runs?
How are these variables being 'evaluated' when the SSIS package executed? I imagine you get this from a table or generating on the 'fly'.
You have the following option :
Capture them and assign them in SSIS variable(s)
In case you are doing something complex - create a variable something like - User::SQLCommand. In this case Use expression to generate the SQL String that needs to be executed in Oracle. Use this in your OLEDB Source Editor as "Sql command from variable" to execute the statement in Oracle
Use a SQL statement to insert the variable details captured in previous step in your intended audit table

We have a requirement to fetch only change data from Source(Oracle) using SSIS Data Tool. We don't want to fetch entire data in Mapping and then do Insert/Update.
We are looking for something like e.g. Using variable and something below
Select * from where Last_update_Date >= Variable
and Variable should get its data as
Variable = Select MAX(Last_update_Date) from
You can use the free Change Data Capture Service for Oracle by Attunity. It will use a log reader to capture changes from Oracle and stage them in a SQL Server database for consumption by the SSIS CDC pipeline.
I have created a temporary table in oracle sql developer but I forgot to save it and now I want to reuse the query but I don't remember the code used then. Is there a process to get query used creation of temp table?
You can use dbms_metadata.get_ddl()
select dbms_metadata.get_ddl('TABLE', 'YOUR_TABLE_NAME_HERE')
from dual;
The result is a CLOB with the complete DDL. You might need to adjust the display in SQL Developer to make the content of that value fully visible (I don't use SQL Developer, so I don't know if that is necessary and if so, what you would need to do)
Edit:
It seems SQL Developer can't display the result of this query properly unless you use the "Run Script" option. And with that you need to use a SET LONG 60000 (or some other big number) before you run it, to see the complete source code:
Is there a way by not manually copy each statement like a SELECT or stored procedure and it's parameters values in debugger mode for executing it into SQL environment? I'm thinking of a box displaying the entire statement in Visual Studio and just copy it's content.
it is inconvenient to copy parameter's values for a query that has 20 parameters by checking each argument.
With a profiler you can obtain the exact command executed in the DB. For example, using "SQL Server 2016 Profiler" you get the following for a SQL query with two parameters:
exec sp_executesql N'SELECT * FROM Orders WHERE customerId=#Param1 AND productId=#Param2',N'#Param1 int,#Param2 int',#Param1=30,#Param2=10
This command can be executed in SSMS.
I have bunch of plsql which has dynamic queries ( ie queries are framed as string and executed with immediate execute function). I want to find the dependent tables and columns for a plsql. I am planning to achieve by GSQL parser. I tried the plsql file as it is, because of dynamic queries, I am not able to get the dependency information. The alternate way is collecting the list of SQL statements executed during the plsql run. How to get sql statement for a plsql and store it a table with unit name mapping ?
Hi you need execute the sql you have saved with execute immediate;
you will get all sql in below oracle view
select * from v$sql;
select * from dba_hist_sqltext;
I'm trying to convert some Informix ESQL to Oracle Pro*C. In the existing Informix code the "SERIAL" data type was used to indicate automatically incrementing columns. According to the Oracle documentation, the Oracle Migration Workbench for Informix should be able to handle this, and it explains that it converts the "SERIAL" data type into a "NUMBER" with an associated Oracle sequence and trigger. However, when trying to run the tool it simply replaces the word "SERIAL" with "ERROR(SERIAL)", so I've been trying to manually add in the trigger/sequence.
Their example here: http://docs.oracle.com/html/B16022_01/ch2.htm#sthref112 shows a way that this can be done. The sequence appears to be fairly straight forward, however when trying to create a trigger like so:
CREATE TRIGGER clerk.TR_SEQ_11_1
BEFORE INSERT ON clerk.JOBS FOR EACH ROW
BEGIN
SELECT clerk.SEQ_11_1.nextval INTO :new.JOB_ID FROM dual; END;
The Pro*C preprocessor picks up the "CREATE" keyword here, and decides that I'm not allowed to use the host variable ":new.JOB_ID", because host variables cannot be used in conjunction with "CREATE" statements.
My question is, is there some way to create a trigger that links an Oracle sequence to a particular column without using a host variable to specify the column name? The Oracle documentation seems to indicate that their migration tool should be able to cope, which means there must be some way of doing this. However all the examples of the trigger use that I have found all use the host variable which causes the preprocessor to complain.
Thank you for your time.
(Note: I've used the trigger/sequence/column names from the example in the Oracle documentation in the example above.)
I managed to resolve the issue by using an "EXEC SQL EXECUTE IMMEDIATE" statement.
char sql_buf[4096+1];
snprintf(sql_buf, 4096, <sql>);
EXEC SQL IMMEDIATE :sql_buf;
This bypasses the preprocessor and therefore allows the statement through without complaint.
It is impossible to create a trigger that links an Oracle sequence to a particular column without using a "host variable" to specify the column name. By the way it isn't "host variable" - just reference. The same trigger may fire on update and insert for example, so you have to specify what you are referencing: new or old variables. You can do it in MS-SQL but not in Oracle.
