[SOLVED] Merge multiple tables

Please pardon me if this question has been raised earlier.
I want to merge three tables together and put it in a hold file, but for some reason following the standard syntax is not helping. Can someone identify what's wrong with what I'm doing?

TABLE FILE TABLE1
MORE
FILE TABLE2
MORE
FILE TABLE3
END

I expect TABLE1 to have merged rows of the TABLE1, TABLE2, TABLE3 in that order, but it keeps rows of only TABLE1.

Thanks in advance!

There are a number of rules to follow to use MORE or Universal Concatenation.

The first thing I noticed is that you don't have a PRINT or SUM statement for your first table.

The second thing is that all of the column names to be printed in all 3 of the masters have to be the same.

Please read the manual on the basics of the TABLE and MORE commands. You don't have a display command or any columns specified.

Your syntax should look something like this:

TABLE FILE TABLE1
PRINT|LIST|SUM|COUNT (one of these)
column1
column2
column3
...
[ON TABLE HOLD AS H001]

MORE
FILE TABLE2
MORE
FILE TABLE3
END


The columns have to be available in all the tables and they must have the same format.

Hi Ginny,

I've modified the syntax as follows, but with same results. What am I missing here?

TABLE FILE TABLE1
PRINT COL1 COL2 COL3
WHERE COL3 LT 4
MORE
FILE TABLE2
PRINT COL1 COL2 COL3
MORE
FILE TABLE3
PRINT COL1 COL2 COL3
END


Thanks!

The PRINT display statement cannot be repeated for each file - it must be specified only once.

I tried above syntax with other tables, and it's working, so I'm guessing columns may not be compatible in my tables. So,
- If columns are not compatible, does it simply ignore those tables?
- Also, how do I find out which columns are not compatible?

Thanks!

Kev,

The columns you're extracting from each of the tables must have the same name and format - if they're not the same name and format, you may define virtual fields to rename/reformat them.

If columns do not correspond you should get warning/error messages.

Take a look at the Master files (.mas) for each table, or run this code for each table:

?FF TABLE1
?FF TABLE2
...
This will display the column names. aliases and formats

Kev,
I would recommend coding it like this with only one print.
TABLE FILE TABLE1
PRINT COL1 COL2 COL3
WHERE COL3 LT 4
MORE
FILE TABLE2
MORE
FILE TABLE3
END

Note that selection criteria (WHERE and IF clauses) only apply to the section in which they are coded. If you want to impose
WHERE COL3 LT 4
on all three FILE retrievals you have to repeat it:
TABLE FILE TABLE1
  PRINT COL1 COL2 COL3
  WHERE COL3 LT 4;
  ON TABLE HOLD AS HOLITALL 
MORE
FILE TABLE2
  WHERE COL3 LT 4;
MORE
FILE TABLE3
  WHERE COL3 LT 4;
END

See "Creating Reports ...(7.6.1)", Appendix C.
