PRB: RQBE Not Generating FROM Clause When .QPR Table Missing (108164)

MORE INFORMATION

The following code demonstrates this behavior. It creates two tables (databases) and creates a query based on them. It then deletes one of the tables and reopens the query. This second time, the FROM list will have been removed from the SQL statement.

   ERASE TBLTEST.QPR
   CLOSE ALL
   SET SAFETY OFF

   CREATE TABLE tbl1 (keyfield c(3))
   INSERT INTO tbl1 (keyfield) VALUES ("AAA")
   INSERT INTO tbl1 (keyfield) VALUES ("BBB")
   INSERT INTO tbl1 (keyfield) VALUES ("CCC")

   SELECT 0

   CREATE TABLE tbl2 (keyfield c(3))
   INSERT INTO tbl2 (keyfield) VALUES ("BBB")
   INSERT INTO tbl2 (keyfield) VALUES ("BBB")
   INSERT INTO tbl2 (keyfield) VALUES ("BBB")
   INSERT INTO tbl2 (keyfield) VALUES ("CCC")
   INSERT INTO tbl2 (keyfield) VALUES ("CCC")
   INSERT INTO tbl2 (keyfield) VALUES ("AAA")

   SELECT tbl1

   WAIT WINDOW "This will now create the query.  Please add TBL2 to the"
   WAIT WINDOW "query as well as the field TBL2.KEYFIELD.  View the SQL"
   WAIT WINDOW "(noticing the FROM line), RUN it and then save"
   WAIT WINDOW "and close it."

   CREATE QUERY tbltest

   SELECT tbl2
   USE
   DELETE FILE tbl2.dbf
   SELECT tbl1

   WAIT WINDOW "I've now deleted the table.  When the RQBE Window "
   WAIT WINDOW "attempts to open again, press Cancel when prompted to"
   WAIT WINDOW "find the TBL2 file.  Add TBL1.KEYFIELD back to the"
   WAIT WINDOW "fields list, and look under View SQL.  Notice that the"
   WAIT WINDOW "list of tables and fields is no longer in the SELECT"
   WAIT WINDOW "Statement."
   MODIFY QUERY tbltest
