SQL dialect
Apache Hive SQL Parser for Java and .NET
General SQL Parser (GSP) parses Apache Hive with a dedicated, hand-tuned grammar — full AST access, offline syntax validation, formatting, rewriting, and column-level data lineage . One commercial SDK, 38 dialects, Java and .NET.
Example
Apache Hive SQL that GSP parses
SELECT myCol1, col2 FROM baseTable
LATERAL VIEW explode(col1) myTable1 AS myCol1;Parse it in Java
import gudusoft.gsqlparser.*;
TGSqlParser parser = new TGSqlParser(EDbVendor.dbvhive);
parser.sqltext = sql; // the Apache Hive 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 Apache Hive
- LATERAL VIEW explode
- LOAD DATA into partitions
- EXPORT/IMPORT TABLE
- FROM-first multi-insert
- Roles and grants
Beyond parsing, the same AST powers table/column extraction, validation, formatting, and column-level lineage for Apache Hive.

Common questions
Do I need a Apache Hive database connection to validate SQL?
No. GSP validates Apache Hive syntax completely offline. You get error line and column positions, the offending token, and a hint — with no server, driver, or credentials involved.
How complete is the Apache Hive grammar?
GSP uses a dedicated hand-tuned grammar for Apache Hive — not a generic SQL grammar with flags. The parser recognizes 335 Apache Hive keywords and knows which 317 of them can also be used as identifiers, which is exactly the kind of edge case that breaks generic parsers.
Can I use the Apache Hive parser from C# / .NET?
Yes. The .NET edition (NuGet package gudusoft.gsqlparser, .NET Standard 2.0) exposes the same API surface as the Java edition, so every Apache Hive parsing feature on this page works in C# and VB.NET.
Can GSP extract column-level lineage from Apache Hive SQL?
Yes. The built-in DataFlowAnalyzer produces column-level lineage, impact analysis, and call graphs from Apache Hive scripts — it is the engine behind Gudu SQLFlow and the lineage integrations for DataHub and OpenMetadata.
