Member Function Documentation

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

inline

1. Checks that the user has privileges to DROP the given table/view
2. Checks that the database and table exists
3. Checks that the table type (TABLE/VIEW) matches the DROP TABLE/VIEW statement Note: Do not analyze tableName because we prefer to report an error indicating that the table/view does not exist even if the table/view name is invalid.
