Example 6 with JavaTypeFactory

use of org.apache.calcite.adapter.java.JavaTypeFactory in project storm by apache.

the class TestCompilerUtils method sqlOverSimpleEquiJoinTables.

public static CalciteState sqlOverSimpleEquiJoinTables(String sql) throws RelConversionException, ValidationException, SqlParseException {
    SchemaPlus schema = Frameworks.createRootSchema(true);
    JavaTypeFactory typeFactory = new JavaTypeFactoryImpl(RelDataTypeSystem.DEFAULT);
    StreamableTable streamableTable = new CompilerUtil.TableBuilderInfo(typeFactory).field("EMPID", SqlTypeName.INTEGER).field("EMPNAME", SqlTypeName.VARCHAR).field("DEPTID", SqlTypeName.INTEGER).build();
    Table table = streamableTable.stream();
    StreamableTable streamableTable2 = new CompilerUtil.TableBuilderInfo(typeFactory).field("DEPTID", SqlTypeName.INTEGER).field("DEPTNAME", SqlTypeName.VARCHAR).build();
    Table table2 = streamableTable2.stream();
    schema.add("EMP", table);
