Istvan Toth created CALCITE-4138: ------------------------------------ Summary: Metadata operations via Avatica turn empty string args to null Key: CALCITE-4138 URL: https://issues.apache.org/jira/browse/CALCITE-4138 Project: Calcite Issue Type: Bug Components: avatica Affects Versions: 1.17.0 Reporter: Istvan Toth Assignee: Istvan Toth
DatabaseMetaData.getTables(), and some other functions have parameters (catalog, schemaPattern), where null and empty String have different semantics. The corresponding protobuf fields in Avatica are Strings, and the Avatica logic turns those args to null. This makes it impossible to filter on actual empty string values. -- This message was sent by Atlassian Jira (v8.3.4#803005)
