Example 1 with ValueMetaResolver

use of org.pentaho.di.trans.dataservice.optimization.ValueMetaResolver in project pdi-dataservice-server-plugin by pentaho.

the class SqlTransGeneratorTest method testDataFormatting.

@Test
public void testDataFormatting() throws Exception {
    SQL sql = new SQL("SELECT * FROM table");
    RowMetaInterface rowMeta = new RowMeta();
    rowMeta.addValueMeta(new ValueMetaString("str"));
    rowMeta.addValueMeta(new ValueMetaDate("time"));
    rowMeta.addValueMeta(new ValueMetaInteger("long"));
    sql.parse(new ValueMetaResolver(rowMeta).getRowMeta());
    SqlTransGenerator generator = new SqlTransGenerator(sql, -1);
    TransMeta transMeta = generator.generateTransMeta();
    RowMetaInterface outputFields = transMeta.getStepFields(generator.getResultStepName());
    Calendar calendar = Calendar.getInstance();
    calendar.clear();
    calendar.set(2016, Calendar.FEBRUARY, 12, 13, 20);
    Object[] row = { "value", calendar.getTime(), 42L };
    assertThat(outputFields.getFieldNames(), arrayContaining("str", "time", "long"));
    assertThat(outputFields.getString(row, 0), is("value"));
    assertThat(outputFields.getString(row, 1), is("2016-02-12"));
    assertThat(outputFields.getString(row, 2), is("42"));
}
