"Parameter (Component List) is empty but is required"
hey
No documents returned on this Talend error within search or google, has it never happened before............. ? REALLY ?
Talend website and community search engine break a phrase down into words, not useful when searching for this error.
Full stop on my development . Trying to call a stored proc with parameters, but cant pass params even though defined within a tFixedFlowInput component
because I get the above error (subject line)
attached file shows component list but no walkthrough's on calling stored proc with params, help on error, no, nothing..... any clues as to what I need to do next?
The parameters section references "Schema Columns" which means columns from the schema passed by the previous component. If your values are present in that data flow, you just add the number of parameters required by your stored procedure and select them from the drop down lists, specifying whether they're IN, OUT, IN OUT or RECORDSET parameters. It doesn't look like the SP component supports using context variables directly.
I am getting the same error. I am not using any external procedures, just trying to read a table into a csv file. I am not clear what you mean by SP component and connection component.
Initially, I set up the Input table by itself and it worked fine.
I then wanted to set the connection once, read in the schemas for the tables and set up queries in the repository and assign them to the database input component. I set up a connection, added two table schemas and two queries... so far so good. When selected the existing connection in the database component configuration tab, every thing was fine except the component list pull down was empty and had no selections. When I ran it, it failed because the component list was empty.
Any clarity on what I am missing would be appreciated.
I figured out the problem. I did not have a database connection component in my job. When I added it to the job, it appeared in the component list. I selected it and it worked.
Sorry for the false alarm but it is nice to have a forum to brainstorm with.
