void com.cloudera.impala.analysis.StatementBase.analyze ( Analyzer analyzer ) throws AnalysisException

inlineinherited

Analyzes the statement and throws an AnalysisException if analysis fails. A failure could be due to a problem with the statement or because one or more tables/views were missing from the catalog. It is up to the analysis() implementation to ensure the maximum number of missing tables/views get collected in the Analyzer before failing analyze().

Implements com.cloudera.impala.analysis.ParseNode.
