Hello,
referring to the ticket with the topic "tMSSQLRow with tsql-Statement using Linked Server" I have the same issue.
I use talend 5.3.1 and want to use "tMSSqlRow" to create a custom SQL. But i end up in only one empty result.
In the same way I do it against a Postgres database with "tPostgressqlRow" and this works fine.
Is this a bug and is there a workaround to get the Result from the SQL?
I've tried to use a "tMSSQLInput" and as long as I do the query against one table it works but if I use a custom query with few different tables joined I get the following exception:
"
Exception in component tMSSqlInput_3
java.sql.SQLException: The executeQuery method must return a result set.
at net.sourceforge.jtds.jdbc.JtdsStatement.executeSQLQuery(JtdsStatement.java:488)
at net.sourceforge.jtds.jdbc.JtdsStatement.executeQuery(JtdsStatement.java:1304)
.......
"
Hope anybody can help me out.
Thanks, Peter
Hi Peter tXXXRow component is usually used to any type of sql statement excepts select statement, we use txxxInput component to execute a select statement, if you use use tXXXRow to execute a select statement, it returns a record set, and you are required to use a tParseRecordSet component after tXXXRow to parse the record sets. You can find a demo job in this page. Shong
The problem is - I am pretty sure - your statement. Your are trying to get an resultset in the advanced settings. The database does not produce a result set as response to your statement. It would be great to see your statement. To develop the correct statement I suggest using a JDBC based database client like SQuirrel: http://squirrel-sql.sourceforge.net/ If you can run your statement here and get a result set, you get it.
Thanks for your reply.
I build the statement in aqua data studio and it worked there. (This is similar to Squirrel)
Here is my SQL:
select distinct
substring(cast(a.object_id as char(36)),1,8)+
SUBSTRING(cast(a.object_id as char(36)),15,4)+
SUBSTRING(cast(a.object_id as char(36)),10,4)+
SUBSTRING(cast(a.object_id as char(36)),27,2)+
SUBSTRING(cast(a.object_id as char(36)),25,2)+
SUBSTRING(cast(a.object_id as char(36)),22,2)+
SUBSTRING(cast(a.object_id as char(36)),20,2)+
SUBSTRING(cast(a.object_id as char(36)),35,2)+
SUBSTRING(cast(a.object_id as char(36)),33,2)+

Hi again,
I simplified my problem down to a simple select to one column of one table and the problem is still the same. I get only one emty result row instead of few thousands I get in Aqua Data Studio.
I added a screenshot of my simple job.
Thank you for helping.
Peter
