Actual behavior

Throws : org.apache.shardingsphere.sql.parser.exception.SQLParsingException: You have an error in your SQL syntax: SELECT [Limit1].[AccountID] AS [AccountID] FROM ( SELECT TOP (1) [AccountID] AS [AccountID] FROM [Account] ) AS [Limit1], null at org.apache.shardingsphere.sql.parser.core.database.parser.SQLParserExecutor.twoPhaseParse(SQLParserExecutor.java:69) at org.apache.shardingsphere.sql.parser.core.database.parser.SQLParserExecutor.parse(SQLParserExecutor.java:48) at org.apache.shardingsphere.sql.parser.api.SQLParserEngine.parse(SQLParserEngine.java:47) at org.apache.shardingsphere.infra.parser.sql.SQLStatementParserExecutor.parse(SQLStatementParserExecutor.java:46) at org.apache.shardingsphere.infra.parser.sql.SQLStatementParserEngine.parse(SQLStatementParserEngine.java:47) at org.apache.shardingsphere.infra.parser.ShardingSphereSQLParserEngine.parse(ShardingSphereSQLParserEngine.java:52) at org.apache.shardingsphere.driver.jdbc.core.statement.ShardingSphereStatement.createQueryContext(ShardingSphereStatement.java:499) at org.apache.shardingsphere.driver.jdbc.core.statement.ShardingSphereStatement.execute0(ShardingSphereStatement.java:428) at org.apache.shardingsphere.driver.jdbc.core.statement.ShardingSphereStatement.execute(ShardingSphereStatement.java:376)

Reason analyze (If you can)

I think Problem lies on Unconventional SQL Server syntax.

Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.

Just Execute the above query.

Example codes for reproduce this issue (such as a github link).

Just execute the SQL using shardingsphere jdbc.
