The Oracle translator did not limit the number of values in "IN" clause, which were required by Oracle database. ---------------------------------------------------------------------------------------------------------------- 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.
