several questions RE tables
in [Getting Started]

From: Ret on 29 Mar 2010 16:13 I'm using Access 2007 and I want to transfer data from one table (an import) to another table. Every time I try an append query I lose most of the records. I've tried to format the records the same and now just about any changes I make in either table I get the messege "Too many fields defined". Help?! -- Ret
From: Steve on 29 Mar 2010 16:22 You can only have 255 fields max in a table.

If you would like help doing so... please tell us how the query is set up; open it in SQL view and post the SQL text here. The "too many fields" suggests that you're repeatedly changing the *STRUCTURE* (not the data) of the table. Each time you add or change a field, you use up one of the 255 allowed field "slots". You can recover them by using Office Button... Manage... Compact and Repair. If you actually have over 255 fields (heck, over 25 fields) then you need to come to a screeching halt and redesign your improperly normalized tables! -- John W. Vinson [MVP]
From: Ret on 29 Mar 2010 19:37 Thank you. I am no longer having problems with the "Too many fields defined". Don't know what changed that. However, I have been unable to transfer a yes/no field properly. Any suggestions? -- Ret "John W.

You probably have "Compact on Close" checked in the database's properties, so it compacted automatically for you. >However, I have been unable to >transfer a yes/no field properly. Any suggestions? Since I have no idea what you're transfering from, transfering to, or how you're doing the transfer, not really. All I can say is that an Access Yes/No field is stored as -1 for Yes, 0 for No, other values (and NULL values) prohibited. -- John W. Vinson [MVP] |
