------------------------------------
Summary: Compilation Error when processing UDF with binary
parameter
Key: CALCITE-680
URL: https://issues.apache.org/jira/browse/CALCITE-680
Project: Calcite
Issue Type: Bug
Reporter: Ng Jiunn Jye
Assignee: Julian Hyde
I am creating Calcite UDF which convert array of byte into string and vice
versa.
For BinaryToString udf, the SqlValidator is expecting the function with
parameter byte[], but during execution, the EnumerableCalc is expecting the
function to take parameter of type ByteString.
Test Sql :
select BinaryToString (x'01020304') from T1
Error Message:
Caused by: org.codehaus.commons.compiler.CompileException: Line 24, Column 84:
No applicable constructor/method found for actual parameters
"org.apache.calcite.avatica.util.ByteString"; candidates are: "public
java.lang.String BinaryToString.eval(byte[])"
Generated Code extract :
public Object current() {
return newBinaryToString().eval(new
org.apache.calcite.avatica.util.ByteString(
new byte[] {
(byte)1,
(byte)2,
(byte)3,
(byte)4}));
}
