> Key: TEIID-4703
> URL: https://issues.jboss.org/browse/TEIID-4703
> Project: Teiid
> Issue Type: Bug
> Affects Versions: 8.13.4
> Reporter: SHI HONG CHIN
> Assignee: Steven Hawkins
>
> Database: Oracle + Firebird + Microsoft SQL Server.
> Oracle limit the maximum number of values in "IN" clause to 1000.
> In teiid, I am using the built-in Oracle translator.
> When running some SQL queries, Oracle database reported an error "No more data to read from socket". I had set the log level of Teiid to "ALL". According to the WildFly log files, Teiid executed a query with more than 10000 values in the "IN" clause.
> I tried to copy the whole SQL from WildFly log file into Oracle SQL Developer and execute it, the same error occurred. Then, I tried to edit the query by delete many values from the "IN" clause and then run the query again, and the query success.
> For teiid, as a workaround, I overrided the oracle translator and set the property of "MaxInCriteriaSize" to 50. After that, all SQL queries run success without any issue.
> I suggest that, by default, the built-in Oracle translator limit the number of values in "IN" clause to maximum 1000 values, and this behavior can be changed through properties.
