[ https://issues.jboss.org/browse/TEIID-2584?page=com.atlassian.jira.plugin... ] Ramesh Reddy commented on TEIID-2584: ------------------------------------- Changed above check to {code:lang=SQL} SELECT * FROM MAT_VIEW WHERE 1 = ALL(SELECT MVSTATUS(Valid, LoadState, OnErrorAction) FROM {statusTbl} WHERE VDBName=? AND VDBVersion=? AND SchemaName=? AND viewName = ?) {code} As I observed from previous check that EXISTS will be true for either valid or invalid situations as along there is a result, even if it is null. So, I choose the above kind of check, that seems work as expected. Also implemented the "wait" action, when matview is not valid or not in "LOADED" state, the user query will wait until the "status" table is shows that the matview is in "LOADED" state with valid set to true. During the wait, the query submits polling commands to check the status of "status" table every 30 seconds. We could make this time-slot configurable if needed. -- This message is automatically generated by JIRA.
