- Define a materialized view using SAP HANA db
- Try to invoke loadMatView for the view and set invalidate=>'true'
There appears to be an issue with loadMatView function.
Specifically when the function is invoked with invalidate=>'true' argument, when it is expected, that invocation of this function invalidates the current contents of the materialized view until the initiated load is completed and new data are populated.
But when calling this function as described, an error occurs:
Unable to find source-code formatter for language: plain. Available languages are: actionscript, ada, applescript, bash, c, c#, c++, cpp, css, erlang, go, groovy, haskell, html, java, javascript, js, json, lua, none, nyan, objc, perl, php, python, r, rainbow, ruby, scala, sh, sql, swift, visualbasic, xml, yaml
TEIID20001 The modeled datatype integer for column 0 doesn't match the runtime type "org.teiid.core.types.ArrayImpl". Please ensure that the column's modeled datatype matches the expected data.
Please note, that there is no column of type array in my schema.
There is declaration of the view:
CREATE VIEW external_long_ttl ( customer_id integer NOT NULL, total_amount integer )
and the query used to load the view:
"teiid_rel:MATVIEW_LOAD_SCRIPT" 'INSERT INTO dv_matviews_mat_view_stage(customer_id,total_amount) SELECT CONVERT(c.id,integer) AS customer_id, CONVERT(SUM(o.amount),integer) AS total_amount FROM dv_matviews_customers c INNER JOIN dv_matviews_orders o ON c.id = o.customer_id GROUP BY c.id;',
Complete definition of the view is:
