As it says in the title, I am trying to extract data from my Informix ODBC source with parameters. I have two parameters that i am trying to pass. Both are DateTime and i am trying to get the current starting date for example 2014-10-10 00:00:00 and the ending date 2014-10-10 23:59:59.
If i do this with a normal query:
SELECT * FROM TABLENAME
WHERE STARTDATETIME BETWEEN '2014-10-10 00:00:00' AND '2014-10-10 23:59:59'
Everything works fine. However, if I try and use the parameters that I have set up:
SELECT * FROM TABLENAME
WHERE STARTDATETIME BETWEEN ? AND ?
I get the following error:
Open Database Connectivity (ODBC) error occurred. state: '07001'.
Native Error Code: -11012. [Informix][Informix ODBC Driver]Wrong number of parameters.
I feel like it has to do with my query, but I have been looking and have found nothing. Would anyone be able to help me out? Thanks!
When you use parameterized query ('?') binding is needed.
Likely you may be using ODBC API SQLBindCol for binding it.
The number of parameter in the query (in this case it is 2)
should be matching with number of bind API calls.
Please check your ODBC code to make sure the binding is correctly done.

I am working on SAP HANA Studio and have tried to run SQL command that converts an entire column of field, nvarchar, into one of field, date.
My dates have format: dd-mon-yyyy (i.e '29-Mar-1997') with field nvarchar(11).
I have looked at previous questions and SQL command documentation (for functions like CAST, CONVERT, TO_DATE, STR_TO_DATE) and have not gotten a solution.
Typical errors I get are: Function not recognized, or, Error while parsing Service Date as DATE at function to_date().
Any suggestions?
Thanks

Try TO_DATE():
select to_date(col, 'DD-MON-YYYY')
Obviously your database driver/layer in SAP HANA does not support all mySQL functions.
Please connect to your database directly (using command-line or a gui like HeidiSQL) and create a view in your database:
CREATE VIEW view_tablename AS
SELECT STR_TO_DATE(`Service Date`, '%d-%b-%Y') AS ServiceDateDt, * FROM tablename
Then use view_tablename instead of tablename in all your queries - because view_tablename has the additional date field "ServiceDateDt".
I am unable to use date_add in the query editor. I am connected to MySQL database
select DATE_ADD(Registrationdate, INTERVAL $P{addday} DAY) from tab
I get the following errors :
a. No viable alternative at input 'INTERVAL'
b. Mismatched input $P{addday} expecting FROM
Any idea on this would be of great help
Thanks

We are connecting Hadoop cloudera CDH distribution through ODBC driver. Queries are generated from SSRS. Few queries are working fine with parameters augmented through ? placeholder. Few other queries with parameters augmented through ? are not executing.
Error [HY000][Cloudera][ImpalaODBC] (100) error while executing a query in Impala[HY000] : AnalysisException : syntax error in line 1 where Date >= ? and Date <= ?
^Encountered : Unexpected characterExpected : Case... Exception : syntax error.
If i remove where Date >= ? and Date <= ? or supply the hard coded value then query is working perfect.
Few other queries with same filter are working perfect.
What should be recommended investigation points?
Where could i get the exact impala transformed query to investigate whether query is generated correct or not ?
You have a couple of options:
/var/log/impalad/audit stores audit logs (at least in CDH). Those logs contain sql_statement field that stores executed sql queries
Impala has a web server running on a 25000 port. You could connect
with your browser and see queries executed (/queries tab).
If you are using Cloudera Manager, you could see all executed impala
queries in "impala/queries"
I have an oledb connection to mssql and an ado.net destination (with odbc driver used) to mysql. The tables are exectly the same and all the columns are working bar one.
The error message received is:
[ADO NET Destination [325]] Error: An exception has occurred during data insertion, the message returned from the provider is: Unable to cast object of type 'System.DateTime' to type 'System.Char[]'.
I've seen similar questions on other data types but the resolution of changing to string does not work here. If I convert to string (has to be length 29 otherwise the conversion step fails) I get the following error message:
[ADO NET Destination [325]] Error: An exception has occurred during data insertion, the message returned from the provider is: ERROR [HY000] [MySQL][ODBC 5.1 Driver][mysqld-5.5.15]Incorrect datetime value: '2011-03-21 11:23:48.573000000' for column 'LastModificationDate' at row 1
Other potentially relevant details:
connection driver- {MySQL ODBC 5.1 Driver}
script run before dataflow - set sql_mode='STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION,ANSI_QUOTES'
Other datetime columns are working
This column has a reasonably high proportion of nulls
mssql spec: [LastModificationDate] [datetime] NULL
mysql spec: LastModificationDate datetime NULL
Has anyone had experience with this issue and could provide some advice on resolving it?
Can you try converting it to string on sql server side in your query using:
convert(char(10),LastModificationDate,111)+' '+convert(char(8),LastModificationDate,108)
This works for me all the time.
I got the same big headache this week. I tried many ways. Thanks God, finnally, one of them worked. Hope it could help you a little bit.
For some columns with the data type of Int, datetime, decimal....,here, I identified as ColumnA, and I used it as datetime type.
1.in Data Flow Source, use SQL Command to retrieve data. Sth like select isnull(ColumnA,'1800-01-01') as ColumnA, C1, C2, ... Cn from Table
Make sure to use Isnull function for all columns with the datatype mentioned before.
2.Excute the SSIS pkg. It should work.
3.Go back to Control Flow, under the data flow task, add SQL Task control to replace the data back. I mean, update the ColumnA from '1800-01-01' to null again.
That works for me. In my situation, I cannot use ignore failure option. Because if I do, I will lose thousands rows of data.
In my application am using JPA entity manager to persist data/fetch data.
em.executeQuery("select * from file_calender_mapping where start_date between :start and :end");
em.setParameter("start",startDate)//startDate is an date object
em.setParameter("end",endDate)//endDate is an date object
List fmlist=em.execute();
The proble is just like this,
"select * from file_calender_mapping where start_date between start and end"
when am passing some date as start= "2011-08-03 05:08:00",and end="2011-08-04 06:08:00"
then the mysql return one row having the start time ="2011-08-03 05:30:00",its good,But
when my application executing such query it dose not returning any row.Actually what i have seen that my application returning value for two different date,but not for same date different time,thats the main problem.
One another thing is my "start" field for Table "file_calender_mapping" datatype is "timestamp".
So what i was thinking that ther may be some problem on JPA/Hibernate
You can try to specify the exact types of parameters as follows:
em.setParameter("start", startDate, TemporalType.TIMESTAMP);
em.setParameter("end",endDate, TemporalType.TIMESTAMP);
I have the strong feeling that you're confusing EntityManager.createQuery() with EntityManager.createNativeQuery() and you're somehow capturing all the exceptions, which somehow makes you don't receive anything back.
I'm assuming that, because I don't think you have a class named file_calender_mapping.
edit
The documentation will explain it better than I do, but a JPA QL query is transformed to the navite sql of the DB using the mapping, while a native query is send as it's to the DB.
Again, I suggest you to read the documentation, it's quite useful.
