Interface AbstractSqlLikeQueryBuilder.ReturningSelectionVisitor

All Superinterfaces:

ExpressionVisitor, SelectionVisitor

All Known Implementing Classes:

SqlQueryBuilder.DefaultReturningSelectionVisitor

Enclosing class:

AbstractSqlLikeQueryBuilder

protected static interface AbstractSqlLikeQueryBuilder.ReturningSelectionVisitor
extends SelectionVisitor

Visitor for handling the columns produced by a dialect-specific UPDATE/DELETE ... RETURNING clause.

Implementations collect the unescaped column names as they are rendered into the SQL and the corresponding DataTypes so that callers can construct the appropriate OUT parameter metadata (for example, when using Oracle's RETURNING INTO mechanism).

Since:

1.0.0
