Examples with SqmCollation org.hibernate.query.sqm.tree.expression.SqmCollation used on opensource projects

Example 1 with SqmCollation

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

the class SemanticQueryBuilder method visitCollateFunction.

@Override
public Object visitCollateFunction(HqlParser.CollateFunctionContext ctx) {
    if (creationOptions.useStrictJpaCompliance()) {
        throw new StrictJpaComplianceViolation(StrictJpaComplianceViolation.Type.COLLATIONS);
    }
    final SqmExpression<?> expressionToCollate = (SqmExpression<?>) ctx.getChild(2).accept(this);
    final SqmCollation castTargetExpression = (SqmCollation) ctx.getChild(4).accept(this);
    return getFunctionDescriptor("collate").generateSqmExpression(asList(expressionToCollate, castTargetExpression), // why not string?
    null, creationContext.getQueryEngine(), creationContext.getJpaMetamodel().getTypeConfiguration());
}

Example 2 with SqmCollation

use of org.hibernate.query.sqm.tree.expression.SqmCollation 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.
