[PECOBLR-388] added real, numeric, char and bigint support in setObject method

[shivam2680]

Description

Added support for REAL, NUMERIC, CHAR and BIGINT data types in PreparedStatement.setObject() method.
setObject(int parameterIndex, Object x, int targetSqlType) allows users to insert values of specific type in queries.

Testing

Unit test
manual test
script:

static Stream<Integer> sqlTypesProvider() {
    return Stream.of(
        Types.BIT,
        Types.TINYINT,
        Types.SMALLINT,
        Types.INTEGER,
        Types.BIGINT,
        Types.FLOAT,
        Types.REAL,
        Types.DOUBLE,
        Types.NUMERIC,
        Types.DECIMAL,
        Types.CHAR,
        Types.VARCHAR,
        Types.DATE,
        Types.TIME,
        Types.TIMESTAMP,
        Types.BINARY,
        Types.NULL,
        Types.OTHER);
  }

  @ParameterizedTest
  @MethodSource("sqlTypesProvider")
  void testSqlTypes(int sqlType) throws SQLException {
      try (Statement stmt = con.createStatement()) {
        stmt.execute("DROP TABLE IF EXISTS main.ms_testing_schema.test_long");
      }
      try (Statement stmt = con.createStatement()) {
        stmt.execute("CREATE TABLE IF NOT EXISTS main.ms_testing_schema.test_long (val VARIANT)");
      }
      String insertSql = "INSERT INTO main.ms_testing_schema.test_long VALUES (?)";
      try (PreparedStatement ps = con.prepareStatement(insertSql)) {
        ps.setObject(1, getSampleValueForType(sqlType), sqlType);
        ps.executeUpdate();
      }
      String selectSql = "SELECT * FROM main.ms_testing_schema.test_long";
      try (ResultSet rs = con.createStatement().executeQuery(selectSql)) {
        printResultSet(rs);
      }
    }
  }

Additional Notes to the Reviewer

[gopalldb]

can we add for REAL also?

[shivam2680]

This is not needed, because we first convert java.Sql.Types into DatabricksType and then into columnInfoType. So, real is already converted to float in getDatabricksTypeFromSQLType, which is passed to getColumnInfoType.

will add integration tests in a different PR
