Detailed Description

Wrapper class for parser and analyzer.

Definition at line 34 of file AnalysisContext.java.

Constructor & Destructor Documentation

com.cloudera.impala.analysis.AnalysisContext.AnalysisContext ( ImpaladCatalog  catalog, TQueryCtx  queryCtx, AuthorizationConfig  authzConfig  )

inline

Definition at line 43 of file AnalysisContext.java.

References com.cloudera.impala.analysis.AnalysisContext.authzConfig_, com.cloudera.impala.analysis.AnalysisContext.catalog_, and com.cloudera.impala.analysis.AnalysisContext.queryCtx_.

Member Function Documentation

void com.cloudera.impala.analysis.AnalysisContext.analyze ( String  stmt ) throws AnalysisException

inline

Parse and analyze 'stmt'. If 'stmt' is a nested query (i.e. query that contains subqueries), it is also rewritten by performing subquery unnesting. The transformed stmt is then re-analyzed in a new analysis context.

The result of analysis can be retrieved by calling getAnalysisResult().

Exceptions

AnalysisException

On any other error, including parsing errors. Also thrown when any missing tables are detected as a result of running analysis.

void com.cloudera.impala.analysis.AnalysisContext.analyze ( String  stmt, Analyzer  analyzer  ) throws AnalysisException

inline

Parse and analyze 'stmt' using a specified Analyzer.
