Examples with TrimSpecification org.hibernate.sql.ast.tree.expression.TrimSpecification used on opensource projects

Example 1 with TrimSpecification

use of org.hibernate.sql.ast.tree.expression.TrimSpecification in project hibernate-orm by hibernate.

the class AnsiTrimEmulationFunctionTest method render.

private String render(Dialect dialect, TrimFunction function, TrimSpec trimSpec, char trimCharacter, String trimSource) {
    SessionFactoryImplementor factory = Mockito.mock(SessionFactoryImplementor.class);
    JdbcServices jdbcServices = Mockito.mock(JdbcServices.class);
    Mockito.doReturn(jdbcServices).when(factory).getJdbcServices();
    Mockito.doReturn(dialect).when(jdbcServices).getDialect();
    StandardSqlAstTranslator<JdbcOperation> walker = new StandardSqlAstTranslator<>(factory, null);
    List<SqlAstNode> sqlAstArguments = new ArrayList<>();
    sqlAstArguments.add(new TrimSpecification(trimSpec));
    sqlAstArguments.add(new QueryLiteral<>(trimCharacter, new BasicTypeImpl<>(CharacterJavaType.INSTANCE, CharJdbcType.INSTANCE)));
    sqlAstArguments.add(new SelfRenderingExpression() {

        @Override
        public void renderToSql(SqlAppender sqlAppender, SqlAstTranslator<?> walker, SessionFactoryImplementor sessionFactory) {
            sqlAppender.appendSql(trimSource);
        }

        @Override
        public JdbcMappingContainer getExpressionType() {
            return null;
        }
    });
    function.render(walker, sqlAstArguments, walker);
    return walker.getSql();
}

Example 2 with TrimSpecification

use of org.hibernate.sql.ast.tree.expression.TrimSpecification in project hibernate-orm by hibernate.

the class TrimFunction method render.

@Override
public void render(SqlAppender sqlAppender, List<? extends SqlAstNode> sqlAstArguments, SqlAstTranslator<?> walker) {
    final TrimSpec specification = ((TrimSpecification) sqlAstArguments.get(0)).getSpecification();
    final Object trimCharacter = ((Literal) sqlAstArguments.get(1)).getLiteralValue();
    final Expression sourceExpr = (Expression) sqlAstArguments.get(2);
    String trim = dialect.trimPattern(specification, (char) trimCharacter);
    new PatternRenderer(trim).render(sqlAppender, Collections.singletonList(sourceExpr), walker);
}
