SQL execution
Available in ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
In a previous section of the manual, we've seen how jOOQ can be used to build SQL that can be executed with any API including JDBC or ... jOOQ. This section of the manual deals with various means of actually executing SQL with jOOQ.
SQL execution with JDBC
JDBC calls executable objects "java.sql.Statement". It distinguishes between three types of statements:
- java.sql.Statement, or "static statement": This statement type is used for any arbitrary type of SQL statement. It is particularly useful with inlined parameters
- java.sql.PreparedStatement: This statement type is used for any arbitrary type of SQL statement. It is particularly useful with indexed parameters (note that JDBC does not support named parameters)
- java.sql.CallableStatement: This statement type is used for SQL statements that are "called" rather than "executed". In particular, this includes calls to stored procedures. Callable statements can register OUT parameters
Today, the JDBC API may look weird to users being used to object-oriented design. While statements hide a lot of SQL dialect-specific implementation details quite well, they assume a lot of knowledge about the internal state of a statement. For instance, you can use the PreparedStatement.addBatch() method, to add a the prepared statement being created to an "internal list" of batch statements. Instead of returning a new type, this method forces user to reflect on the prepared statement's internal state or "mode".
jOOQ is wrapping JDBC
These things are abstracted away by jOOQ, which exposes such concepts in a more object-oriented way. For more details about jOOQ's batch query execution, see the manual's section about batch execution.
The following sections of this manual will show how jOOQ is wrapping JDBC for SQL execution
Alternative execution modes
Just because you can, doesn't mean you must. At the end of this chapter, we'll show how you can use jOOQ to generate SQL statements that are then executed with other APIs, such as Spring's JdbcTemplate, or Hibernate. For more information see the section about alternative execution models.
