------------------------------------
Summary: Could not resolve VIEW with SimpleCalciteSchema
Key: CALCITE-1571
URL: https://issues.apache.org/jira/browse/CALCITE-1571
Project: Calcite
Issue Type: Bug
Components: core
Affects Versions: 1.11.0
Reporter: Maryann Xue
Assignee: Maryann Xue
The current implementation (ever since its first version) of
SimpleCalciteSchema.getImplicitTableBasedOnNullaryFunction() is wrong, but it
was not revealed until [~julianhyde]'s check-in for CALCITE-1563.
The implementation 1) did not use "tableName" in finding the functions at all;
2) was caching based.
{code}
protected TableEntry getImplicitTableBasedOnNullaryFunction(String tableName,
boolean caseSensitive) {
for (String s : schema.getFunctionNames()) {
for (Function function : schema.getFunctions(s)) {
if (function instanceof TableMacro
&& function.getParameters().isEmpty()) {
final Table table = ((TableMacro) function).apply(ImmutableList.of());
return tableEntry(tableName, table);
}
}
}
return null;
}
{code}
