[jira] [Updated] (CALCITE-6977) A SqlDelete that it is created by SqlDelete.Operator need to support unparse
[ https://issues.apache.org/jira/browse/CALCITE-6977?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Wei.Zhou updated CALCITE-6977:
------------------------------
Description:
When i use SqlDelete.Operator to created a SqlDelete , then try to call toString method unparse to string, it will throw a exception like below:
java.lang.UnsupportedOperationException: class org.apache.calcite.sql.SqlSyntax$7: SPECIALjava.lang.UnsupportedOperationException: class org.apache.calcite.sql.SqlSyntax$7: SPECIAL
at org.apache.calcite.util.Util.needToImplement(Util.java:1080) at org.apache.calcite.sql.SqlSyntax$7.unparse(SqlSyntax.java:128) at org.apache.calcite.sql.SqlOperator.unparse(SqlOperator.java:377) at org.apache.calcite.sql.SqlDialect.unparseCall(SqlDialect.java:453) at org.apache.calcite.sql.SqlCall.unparse(SqlCall.java:103) at org.apache.calcite.sql.SqlNode.toSqlString(SqlNode.java:155)
This exception can be reproduced as below:
{{@Test void testSqlDeleteSqlBasicCallToString() throws Exception {}}
{{ final String sql = "delete from employees where id = 1 ";}}
{{ final SqlNode sqlNode = parseSql(sql);}}
{{ final SqlDelete sqlDelete = (SqlDelete) sqlNode;}}
{{ final SqlCall call = SqlDelete.OPERATOR.createCall((sqlDelete).getFunctionQuantifier(),}}
{{ sqlDelete.getParserPosition(), }}{{sqlDelete.getOperandList());}}
{{ System.out.println(call.toString());}}
{{}}}
