Example 1 with SqmDurationUnit

use of org.hibernate.query.sqm.tree.expression.SqmDurationUnit in project hibernate-orm by hibernate.

the class ArgumentTypesValidator method validate.

/**
 * We do an initial validation phase with just the SQM tree, even though we don't
 * have all typing information available here (in particular, we don't have the
 * final JDBC type codes for things with converters) because this is the phase
 * that is run at startup for named queries, and can be done in an IDE.
