Version 2.3.7 can solve my problem.
version 2.3.5 Zetaengine parse SelectExpressionItem:
`SelectExpressionItem expressionItem = (SelectExpressionItem) selectItem;
Expression expression = expressionItem.getExpression();
if (expressionItem.getAlias() != null) {
fieldNames[idx] = expressionItem.getAlias().getName();
} else {
if (expression instanceof Column) {
fieldNames[idx] = ((Column)
expression).getColumnName();
} else {
fieldNames[idx] = expression.toString();
}
}`
version 2.3.7 Zetaengine parse SelectExpressionItem:
` SelectExpressionItem expressionItem = (SelectExpressionItem) selectItem;
Expression expression = expressionItem.getExpression();
if (expressionItem.getAlias() != null) {
String aliasName = expressionItem.getAlias().getName();
if (aliasName.startsWith(ESCAPE_IDENTIFIER)
&& aliasName.endsWith(ESCAPE_IDENTIFIER)) {
aliasName = aliasName.substring(1,
aliasName.length() - 1);
}
fieldNames[idx] = aliasName;
} else {
if (expression instanceof Column) {
fieldNames[idx] = ((Column)
expression).getColumnName();
} else {
fieldNames[idx] = expression.toString();
}
}`
