---------------------------------
Summary: code gen error for UNARY_MINUS operator call with decimal
type operands
Key: CALCITE-2854
URL: https://issues.apache.org/jira/browse/CALCITE-2854
Project: Calcite
Issue Type: Bug
Components: core
Affects Versions: 1.18.0
Reporter: Lai Zhou
Assignee: Julian Hyde
case:
{code:java}
@Test public void test() throws Exception {
final String cr = "create table t (a DECIMAL)";
final String se = "select -a as aa from t";
Connection c = connect();
Statement s = c.createStatement();
s.execute(cr);
s.executeQuery(se);
}
{code}
error msg:
{code:java}
Caused by: org.codehaus.commons.compiler.CompileException: Line 21, Column 71:
Object of type "java.math.BigDecimal" cannot be converted to a numeric type
{code}
{code:java}
public Object current() {
final java.math.BigDecimal current = inputEnumerator.current() == null ?
(java.math.BigDecimal) null :
org.apache.calcite.runtime.SqlFunctions.toBigDecimal(inputEnumerator.current());
return current == null ? (java.math.BigDecimal) null : - current;
}
{code}
`- current` is not right ,we'd better constructor a new BigDecimal object to to
replace this code snippet，like
{code:java}
return current == null ? (java.math.BigDecimal) null :
SqlFunctions.negativeDecimal(current);
{code}
