base on JSqlParser parses an SQL statement and translate it into a hierarchy of Java classes. The generated hierarchy can be navigated using the Visitor Pattern # [JSqlParser 5.1 Website](https://jsqlparser.github.io/JSqlParser) <img src="src/site/sphinx/_images/logo-no-background.svg" alt="drawing" width="200" align="right"/> [](https://github.com/JSQLParser/JSqlParser/actions/workflows/ci.yml) [](https://coveralls.io/r/JSQLParser/JSqlParser?branch=master) [](https://www.codacy.com/gh/JSQLParser/JSqlParser/dashboard?utm_source=github.com&amp;utm_medium=referral&amp;utm_content=JSQLParser/JSqlParser&amp;utm_campaign=Badge_Grade) [](http://maven-badges.herokuapp.com/maven-central/com.github.jsqlparser/jsqlparser) [](https://www.javadoc.io/doc/com.github.jsqlparser/jsqlparser) [](https://gitter.im/JSQLParser/JSqlParser?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge) A huge thank you to our sponsor, [Starlake.ai](https://starlake.ai/) who simplifies data ingestion, transformation, and orchestration, enabling faster delivery of high-quality data. Starlake has been instrumental in providing Piped SQL and numerous test cases for BigQuery, Redshift, DataBricks, and DuckDB. Show your support for ongoing development by visiting Starlake.ai and giving us a star! ## Summary Please visit our [WebSite](https://jsqlparser.github.io/JSqlParser) for detailed information. **JSqlParser** is a RDBMS agnostic SQL statement parser. It translates SQL statements into a traversable hierarchy of Java classes (see [Samples](https://jsqlparser.github.io/JSqlParser/usage.html#parse-a-sql-statements)): ```sql SELECT 1 FROM dual WHERE a = b /* produces the following AST SQL Text └─Statements: statement.select.PlainSelect ├─selectItems: statement.select.SelectItem │ └─LongValue: 1 ├─Table: dual └─where: expression.operators.relational.EqualsTo ├─Column: a └─Column: b */ ``` ```java String sqlStr = "select 1 from dual where a=b"; PlainSelect select = (PlainSelect) CCJSqlParserUtil.parse(sqlStr); SelectItem selectItem = select.getSelectItems().get(0); Assertions.assertEquals( new LongValue(1) , selectItem.getExpression()); Table table = (Table) select.getFromItem(); Assertions.assertEquals("dual", table.getName()); EqualsTo equalsTo = (EqualsTo) select.getWhere(); Column a = (Column) equalsTo.getLeftExpression(); Column b = (Column) equalsTo.getRightExpression(); Assertions.assertEquals("a", a.getColumnName()); Assertions.assertEquals("b", b.getColumnName()); ``` ## Support for `Piped SQL` Work is progressing for parsing `Piped SQL`, a much saner and more logical way to write queries in its semantic order. ```sql FROM Produce |> WHERE item != 'bananas' AND category IN ('fruit', 'nut') |> AGGREGATE COUNT(*) AS num_items, SUM(sales) AS total_sales GROUP BY item |> ORDER BY item DESC; ``` For details, please see https://storage.googleapis.com/gweb-research2023-media/pubtools/1004848.pdf, https://cloud.google.com/bigquery/docs/reference/standard-sql/pipe-syntax and https://duckdb.org/docs/sql/query_syntax/from.html#from-first-syntax ## Java Version JSQLParser-4.9 was the last JDK8 compatible version. JSQLParser-5.0 and later depend on JDK11 and introduce API breaking changes to the AST Visitors. Please see the Migration Guide for the details. Building JSQLParser-5.1 and newer with Gradle will depend on a JDK17 toolchain due to the used plugins. ## [Supported Grammar and Syntax](https://jsqlparser.github.io/JSqlParser/syntax.html) **JSqlParser** aims to support the SQL standard as well as all major RDBMS. Any missing syntax or features can be added on demand. | RDBMS | Statements | |-----------------------------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------| | Oracle<br>MS SQL Server and Sybase<br>Postgres<br>MySQL and MariaDB<br>DB2<br>H2 and HSQLDB and Derby<br>SQLite | `SELECT`<br>`INSERT`, `UPDATE`, `UPSERT`, `MERGE`<br>`DELETE`, `TRUNCATE TABLE`<br>`CREATE ...`, `ALTER ....`, `DROP ...`<br>`WITH ...` | | Salesforce SOQL | `INCLUDES`, `EXCLUDES` | | Piped SQL (also known as FROM SQL) | | **JSqlParser** can also be used to create SQL Statements from Java Code with a fluent API (see [Samples](https://jsqlparser.github.io/JSqlParser/usage.html#build-a-sql-statements)). ## Sister Projects If you like JSqlParser then please check out its related projects: * [JSQLFormatter](https://manticore-projects.com/JSQLFormatter/index.html) for pretty printing and formatting SQL Text * [JSQLTranspiler](https://manticore-projects.com/JSQLTranspiler/index.html) for dialect specific rewriting, SQL Column resolution and Lineage, provided by [Starlake.ai](https://starlake.ai/) ## Alternatives to JSqlParser? [**General SQL Parser**](http://www.sqlparser.com/features/introduce.php?utm_source=github-jsqlparser&utm_medium=text-general) looks pretty good, with extended SQL syntax (like PL/SQL and T-SQL) and java + .NET APIs. The tool is commercial (license available online), with a free download option. Alternatively the dual-licensed [JOOQ](https://www.jooq.org/doc/latest/manual/sql-building/sql-parser/) provides a handwritten Parser supporting a lot of RDBMS, translation between dialects, SQL transformation, can be used as a JDBC proxy for translation and transformation purposes. ## [Documentation](https://jsqlparser.github.io/JSqlParser) 1.
