问题 I have a CSV file and a database table as inputs. I need to keep all the records that are in the database table but exclude those that are in the CSV file. It all gets written to a CSV file in the end. All my attempts have resulted in hundreds of duplicates so I'm rather challenged here. 回答1: This is a quick-and-dirty trick, but it should fit your needs. Connect your database and your CVS input to a TMap- Use your DB as main connection and CSV as Lookup. Something like: tMySqlInput---->Main--

问题 Hello and thank you for your time, I have been searching everywhere online for an example, where a SQL trigger will run an external application, but I have had no luck. All I am seeing is that the EXEC will execute a SQL procedure. The reason I need this is, I have a SQL Server 2010 with many tables and when an update or insert occurs on certain tables I need my Talend job to run and update the Salesforce tables. Currently the Talend jobs are running through A task scheduler but the company

问题 I want to load excel files into the mysql database and check that they do not already exist, my problem is that I can not extract the name of the current file. For example, I have the following files A.xlsx , B.xlsx and C.xls . It return always B.xlsx 回答1: I think the issue you have is that your "RunIf" link is before the iterator, and therefore it's not being triggered at the right time. The image below shows a simplified version, where I list the rows in the spreadsheets and then the file

问题 This seems to be a weird situation, but I want to know (have googled in Talend forums and their API docs, but nothing) if it is possible to set the context parameters for an already deployed task in TAC without actually running it . I say that last part because I already know how and have the ability to run a specified job with the right context parameter values, but that's actually a step further than I need to go. Thanks for any input 回答1: You can use the metaservlet API-s updateTask

问题 I am using Talend to populate a data warehouse. My job is writing customer data to a dimension table and transaction data to the fact table. The surrogate key (p_key) on the fact table is auto-incrementing. When I insert a new customer, I need my fact table to reflect the id of the related customer. As I mentioned my p_key is auto auto_incrementing so I can't just insert an arbitrary value for the p_key. Any thought on how I can insert a row into my dimension table and still retrieve the

问题 In "Talend Data Integration" I want to create a connection using JDBC to a Progress OpenEdge database. I have no experience whatsoever with this type of connection. My ODBC-connections to the same resources work fine, but Talend requires a JDBC connection to function properly. The connection settings in Talend I have at the moment are: DB Type: General JDBC JDBC URL: jdbc:sqlserver://db-name:port;databaseName= * * Driver jar: ??? (which jar-file do I need for OpenEdge?) Class name: ??? (which

问题 In a data flow from one table to another, I would like to cast a date. The date leaves the source table as a string in this format: "2009-01-05 00:00:00:000 + 01:00". I tried to convert this to a date using a tConvertType, but that is not allowed apparently. My second option is to cast this string to a date using a formula in a tMap component. At the moment I tried these formulas: - TalendDate.formatDate("yyyy-MM-dd",row3.rafw_dz_begi); - TalendDate.formatDate("yyyy-MM-dd HH:mm:ss",row3.rafw
