Ganesha Shreedhara updated HIVE-22963:
--------------------------------------
Comment: was deleted
(was: [~pxiong] Can you please help with understanding if this is an expected
behaviour? Does it require escaping double quote if it is is enclosed between
single quotes in the parameter of a function? Also SelectClauseParser is able
to parse the SelectExpression here, the exception is actually thrown by
FromClauseParser even though the escaping is required in SelectExpression.
I suspect that this behaviour is because of the changes done as part of
https://issues.apache.org/jira/browse/HIVE-12764. Please check and advise. )

> Key: HIVE-22963
> URL: https://issues.apache.org/jira/browse/HIVE-22963
> Project: Hive
> Issue Type: Bug
> Components: Parser
> Affects Versions: 3.1.1, 2.3.6
> Reporter: Ganesha Shreedhara
> Assignee: Ganesha Shreedhara
> Priority: Major
>
> Parsing of query fails when we use single or double quotes in from/to string
> of translate function in 2.3*/3.1.1 version of hive. Parsing of the same
> query is successful in 2.1.1 version of hive.
> *Steps to reproduce:*
>
> {code:java}
> CREATE TABLE test_table (data string);
> INSERT INTO test_table VALUES("d\"a\"t\"a");
> select translate(data, '"', '') from test_table;
> {code}
>
>
> Parsing fails with the following exception:
> {code:java}
> NoViableAltException(355@[157:5: ( ( Identifier LPAREN )=>

> Parsing is successful when double quote is escaped.
> The following query works:
>
> {code:java}
> SELECT translate(data, '\"', ' ') from test_table;
> {code}
>
> But the behaviour which looks buggy is when the double quote is not escaped
> in from/to string of translate function, it seems to be interpreting the
> double quote in from/to string of next translate function as ending quote.
> Parsing is successful for the following queries.
>
> {code:java}
> select translate(data, '"', ''), translate(data, '"', '') from test_table;
> select translate(data, '"', ''), translate(data, ' ', '"') from test_table;
> select translate(data, "'", ""), translate(data, "'", "") from test_table;
> select translate(data, "'", ""), translate(data, " ", "'") from test_table;
> select translate(data, '"', '"') from test_table;
> select translate(data, "'", "'") from test_table;
> {code}
>
> The same behaviour exists when we use any other built-in functions or UDFs.
