AWS Athena SQL Parser for Java and .NET

Example

AWS Athena SQL that GSP parses

CREATE EXTERNAL TABLE logs (id STRING, ts TIMESTAMP)
ROW FORMAT SERDE 'org.openx.data.jsonserde.JsonSerDe'
LOCATION 's3://my-bucket/logs/';

Parse it in Java

import gudusoft.gsqlparser.*;

TGSqlParser parser = new TGSqlParser(EDbVendor.dbvathena);
parser.sqltext = sql; // the AWS Athena SQL above
if (parser.parse() == 0) {
    System.out.println(parser.sqlstatements.size() + " statement(s) parsed");
} else {
    System.out.println(parser.getErrormessage());
}

The .NET edition exposes the same API in C# — see the C# quick start.

Coverage

What GSP handles in AWS Athena

• CREATE EXTERNAL TABLE with SerDe
• CTAS (CREATE TABLE AS)
• UNLOAD
• ALTER TABLE RENAME PARTITION
• ROW and complex types

Beyond parsing, the same AST powers table/column extraction, validation, formatting, and column-level lineage for AWS Athena.

Actively maintained
