Determine the table field differences

Looking for code to determine the differences between two tables' number of fields and which table does not have the certain fields.

I need to compare two tables between different databases and determine in variances in the number of fields and which tables/fields are different.

Looking for code to determine the differences?

can't get FMS - company does not have license - can't buy one either.  Looking for freeware or shareware.

I have several databases versions of the same database where some of the older version's table structure has not been updated to include newer fields.  Trying to determine which version and tables contain these discrepancies and some how programically allow these differences in my latest version of the database.

Table1.PartnerID & table2 does not contain field for PartnerID.

If table 2 is different I need to change the record source for the form to create a temp field in my query for the Partner field so I do not get a missing object error.

any ideas?

I want to see which table contains the field PartnerID and which of the two tables don't - and if there is a difference the create a query to look like.

Table 1 - Select RecID, EmployeeName, PartnerID from table1
Table 2 = Select RecID, EmployeeName, "" as PartnerID from table2  

changing the record source for the data Entry form to "Select RecID, EmployeeName, "" as PartnerID from table2 "  etc.

I just want to identify which tables do not contain the same # of fields

So compare field count of Table 1 to Field Count of Table 2, if different, then determine which fields are missing from Table 2 and create a recordsource that allows for the missing fields.

Hope this helps you understand.

Since each of the older versions' table structure may have several missing fields.

I can not change the actual older versions table structure I just want to bring in the older tables where applicable and handle any discrepancies that could cause the latest version of the database to display error messages for missing fields.

As you probably know from previous post my database designs are not the most relationship oriented.  I have 100's copies of the the databases where the versions vary.  I can't change to a proper FE & BE situation.  I am stuck with what I have I just want to be able to push out the latest updates to ever version so I do not have multiple versions of the databases out there.  But in order to accomplish I need to be able to handle the variances in the table structures.  I have looked into version control, but still run into the differences in the actual structure issues.  The older databases are well into their life cycle and I cannot disrupted, trying to accomplish this task is humongous.

For the Partner detail info - some of the older versions will not have this type of data in their databases and this is just one example of the issues facing me.
