Pavel Pereslegin updated IGNITE-20976:
--------------------------------------
Epic Link: IGNITE-20453
> Sql. Multistatement dynamic parameters adjusting works incorrect for DELETE
> operator.
> -------------------------------------------------------------------------------------
>
> Key: IGNITE-20976
> URL: https://issues.apache.org/jira/browse/IGNITE-20976
> Project: Ignite
> Issue Type: Bug
> Components: sql
> Reporter: Pavel Pereslegin
> Priority: Major
> Labels: ignite-3
>
> Normalized statement cannot be obtained for 'DELETE' statement with dynamic
> parameters.
> It seems that after adjusting the dynamic parameters (see
> {{ScriptParseResult.SqlDynamicParamsAdjuster}}), the new tree cannot be
> converted to a string.
> Reproducer:
> {code:java}
> @Test
> public void testScriptDelete() {
> String query1 = "SELECT 1;";
> String query2 = "DELETE FROM TEST WHERE ID=?";
> // Parse separately - ok.
> StatementParseResult res1 = IgniteSqlParser.parse(query1,
> StatementParseResult.MODE);
> StatementParseResult res2 = IgniteSqlParser.parse(query2,
> StatementParseResult.MODE);
> System.out.println(res1.statement().toString());
> System.out.println(res2.statement().toString());
> // Parse script throws "UnsupportedOperationException" for
> `toString()` from `DELETE` statement.
> ScriptParseResult scriptRes = IgniteSqlParser.parse(query1 + query2,
> ScriptParseResult.MODE);
> for (StatementParseResult res : scriptRes.results()) {
> System.out.println(res.statement().toString());
> }
> }
> {code}
> Output
> {noformat}
> SELECT 1
> DELETE FROM `TEST`
> WHERE `ID` = ?
> SELECT 1
> java.lang.UnsupportedOperationException: class
