Hi,<br>
<br>
We are using Crystal report 2008 CR4E API to implement the crystal report in our application. We use the below code to reset the report data source with our application data source. It works fine for most of the simple queries. But if the query contains any function defined in the SELECT Clause it throws Unexpected Database Connector error. As per the log and analysis we believe the root cause of the exception is it consider that function as column in the table and throws the SQL Exception that "function is Invalid Identifier". Could you please help in resolving this issue?
<br><br>
Code:<br><br>
Tables tables = clientDoc.getDatabaseController().getDatabase().getTables(); <br>
for(int i = 0;i < tables.size();i++){<br>
origTable = tables.getTable(i);<br>
if (tableName == null || origTable.getName().equals(tableName)) {<br>
newTable = (ITable)origTable.clone(true);<br>
newTable.setQualifiedName(origTable.getAlias());<br>
connectionInfo = newTable.getConnectionInfo();<br>
propertyBag = new PropertyBag();<br>
propertyBag.put("Trusted_Connection", params.trustedCon);<br>
propertyBag.put("Server Type", params.serverType);<br>
propertyBag.put("Use JDBC", params.useJdbc);<br><br>
propertyBag.put("Database DLL",params.databaseDLL);<br>
propertyBag.put("Connection URL", params.connectionURL);<br>
propertyBag.put("Database Class Name", params.dbClassName);<br>
connectionInfo.setAttributes(propertyBag);<br>
connectionInfo.setUserName(params.userName);<br>
connectionInfo.setPassword(params.password);<br>
clientDoc.getDatabaseController().setTableLocation(origTable, newTable); // Exception is thrown here<br>
} <br>
} <br>
<br>
SQL Query : <br><br>
Select empno, Fun_getEmpAddress(empno) from employee where empno = ?<br><br><br>
