             Summary: Unable to sum decimal values which have non-default 
precision
                 Key: IGNITE-17438
                 URL: https://issues.apache.org/jira/browse/IGNITE-17438
             Project: Ignite
          Issue Type: Bug
            Reporter: Ivan Gagarkin


Version: the current master branch

Found the bug when creating unit tests. 

Steps to reproduce:
{code:java}
cache.query(new SqlFieldsQuery(
    """
      | CREATE TABLE numbers (
      |    id LONG,
      |    val DOUBLE,
      |    int_val LONG,
      |    decimal_val DECIMAL(5, 5),
      |    PRIMARY KEY (id)) WITH "backups=1"
    """.stripMargin)).getAll

 cache.query(qry.setArgs(18L.asInstanceOf[JLong], new 
java.math.BigDecimal(2.5))).getAll
cache.query(qry.setArgs(19L.asInstanceOf[JLong], new 
java.math.BigDecimal(3.5))).getAll
cache.query(qry.setArgs(20L.asInstanceOf[JLong], new 
java.math.BigDecimal(4.5))).getAll
cache.query(qry.setArgs(21L.asInstanceOf[JLong], new 
java.math.BigDecimal(4.5))).getAll

cache.query(new SqlFieldsQuery("SELECT SUM(decimal_val) FROM numbers WHERE id 
IN (18, 19, 20)")).getAll{code}
Result:
{code:java}
class org.apache.ignite.internal.processors.query.IgniteSQLException: Numeric 
value out of range: "5"; SQL statement:
SELECT
CAST(CAST(SUM(__C0_0) AS DECIMAL(5, 5)) AS DECIMAL(5, 5)) __C0_0
FROM PUBLIC.__T0 [22003-197] {code}
