Trino SQL Parser for Java

Trino SQL that GSP parses

SELECT student, score
FROM tests
CROSS JOIN UNNEST(scores) AS t(score);

Parse it in Java

import gudusoft.gsqlparser.*;

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

Java edition only. The .NET library has no Trino grammar, so this dialect cannot be parsed from C# or VB.NET. See the .NET SQL Parser SDK for the dialects it does cover.

What GSP handles in Trino

• UNNEST of arrays
• PREPARE/EXECUTE
• CREATE TABLE ... LIKE
• EXPLAIN

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