problems with dbExpress connecting to DB2. Get error: SQL0204N "tablename" is an undefined name. SQLSTATE-42704

By: Angel Martinez

Abstract: explains how to work around the SQLSTATE-42704 error


When using dbExpress and accessing a table on a DB2 database, if I have a select statement in the CommandText property of a TSQLDataSet in the form:
select * from employee
the following error is raised when attempting to apply updates:
Project TestDBX.exe raised exception class EDatabaseError with message '[IBM][CLI Driver][DB2/NT] SQL0204N "employee" is an undefined name. SQLSTATE-42704
This error is raised even after verifying that employee is a valid table in the database.


The way dbExpress handles the SQL statement requires the Table Name and the Schema Name to be in Upper Case letters. In the CommandText property, change the sql statement to:
select * from EMPLOYEE
and the error listed above should go away.
