/**
|
||||
* This type is used for the {@link Insert}'s DSL API.
|
||||
* <p>
|
||||
* Example: <code><pre>
|
||||
* DSLContext create = DSL.using(configuration);
|
||||
*
|
||||
* create.insertInto(table, field1, field2)
|
||||
* .values(value1, value2)
|
||||
* .values(value3, value4)
|
||||
* .onConflict(field1)
|
||||
* .doUpdate()
|
||||
* .set(field2, value2)
|

* .where(field3.eq(value5))

|
||||
* <p>
|
||||
* <h3>Referencing <code>XYZ*Step</code> types directly from client code</h3>
|
||||
* <p>
|
||||
* It is usually not recommended to reference any <code>XYZ*Step</code> types
|
||||
* directly from client code, or assign them to local variables. When writing
|
||||
* dynamic SQL, creating a statement's components dynamically, and passing them
|
||||
* to the DSL API statically is usually a better choice. See the manual's
|
||||
* section about dynamic SQL for details: <a href=
|
||||
* "https://www.jooq.org/doc/latest/manual/sql-building/dynamic-sql">https://www.jooq.org/doc/latest/manual/sql-building/dynamic-sql</a>.
|
||||
* <p>
|
||||
* Drawbacks of referencing the <code>XYZ*Step</code> types directly:
|
||||
* <ul>
|
||||
* <li>They're operating on mutable implementations (as of jOOQ 3.x)</li>
|
||||
* <li>They're less composable and not easy to get right when dynamic SQL gets
|
||||
* complex</li>
|
||||
* <li>They're less readable</li>
|
||||
* <li>They might have binary incompatible changes between minor releases</li>
|
||||
* </ul>
