[teiid-issues] [JBoss JIRA] (TEIID-3600) DB2 - error getting substring if "from position" is out of range

[Van Halbert (JIRA)]

     [ https://issues.jboss.org/browse/TEIID-3600?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Van Halbert reopened TEIID-3600:
--------------------------------


The issue is still present. Source-specific command has changed, but exception is thrown anyway.

Source-specific command: SELECT substr(varchar(g_0.TIMESTAMPVALUE), CASE WHEN 40 > 0 THEN 0 ELSE 40 END, CASE WHEN 0 > (length(varchar(g_0.TIMESTAMPVALUE)) - (CASE WHEN 40 > 0 THEN 0 ELSE 40 END - 1)) THEN (length(varchar(g_0.TIMESTAMPVALUE)) - (CASE WHEN 40 > 0 THEN 0 ELSE 40 END - 1)) ELSE 0 END) FROM SMALLA AS g_0 WHERE g_0.INTKEY = 1

Result: Caused by: com.ibm.db2.jcc.am.SqlDataException: DB2 SQL Error: SQLCODE=-138, SQLSTATE=22011, SQLERRMC=null, DRIVER=4.12.55
