Welcome to JSQL. It's a lightweight JDBC DSL framework, JSQL meansJust SQL and without ORM configuration.It is a framework which is convenience and easy to use, just like sql syntax that you feel free to write SQL as usual andmakes Java SQL development more easier.

If you are a Java developer searching for the jdbc framework satisfy functions as connection pool, super lightweight ormand want to write sql like java code programing, then I suggest you could try to use JSQL framework for jdbc operation.

JSQL for Reasons:

• No SQL string and keep your code graceful
• No ORM bean code generation mass your git control
• Provide ExecutorPool/ConnectionPool for jdbc connection pooling without DBCP dependencies

• JDK6 or higher

1. Connection/JdbcExecutor pool
2. SQL syntax like builder
3. Transaction
4. Support customizing dialects
5. Pagination
6. Jdbc executor for query, update or batch update
7. Super lightweight ORM
8. Against SQL inject
9. Logging ability

1. Cubrid
2. SQLite
3. DB2
4. Derby (EmbeddedDerby/NetworkDerby)
5. H2
6. MariaDB
7. MySQL
8. Oracle
9. PostgreSQL
10. SQLServer2012(version >= 2012)

SQL: select * from table where name = ?Value: [jsql]

JSQLDataSourcedataSource =JSQLDataSource.newDataSourceBuilder()                            .url("jdbcUrl").user("jsql").password("pass").build();dataSource.transaction(tx -> {tx.insert("table")      .values(Cond.eq("col1","val1"),Cond.eq("col2",102),Cond.eq("col3","val3"))      .execUpdate();// if exception thrown will call tx.rollback()// tx.commit(); // auto commit if transaction ended});

SQL: insert into table(col1,col2,col3) values(?,?,?)VALUE: ["val1", 102, "val3"]

Using standalone Transaction to control commit or rollback operation as your favour

JSQLDataSourcedataSource =JSQLDataSource.newDataSourceBuilder()                            .url("jdbcUrl").user("jsql").password("pass").build();TransactionDataSourcetx =dataSource.transaction();tx.insert("table")  .values(Cond.eq("col1","val1"),Cond.eq("col2",102),Cond.eq("col3","val3"))  .execUpdate();tx.close();// auto commit

SQL: insert into table(col1,col2,col3) values(?,?,?)VALUE: ["val1", 102, "val3"]

NOTE

Above examples are using JSQLDataSource inner Connection pool to execute SQL generated by JSQL.
