Dumindu Buddhika commented on PHOENIX-1705:
-------------------------------------------
Thanks for the suggestions [~jamestaylor],
For the first case, actually element comes as FixedWidth(it comes as an
Integer). So adding getElementExpr().getDataType().isFixedWidth() condition did
not work since the elementType is "integer" and maxLength returns a 10. That is
the problem. Can you think why this happens?
For the second case, when ARRAY_APPEND(null,null), getArrayExpr().getDataType()
returns null . But since null values are allowed for element,
{code} @FunctionParseNode.Argument(allowedTypes =
{PVarbinary.class},defaultValue = "null")}{code}
getElementExpr().getDataType() returns "PVarBinary". So
{code}ARRAY_APPEND(ARRAY[2,3],null){code} still fails at constructor(coercion
check. Here we have to return the input array itself). how should I go about
this? Having !getElementExpr().isNullable() in the coercion check condition
solves the problem. Is it ok to do so?
