Limitations
Database Version: 8.00
- Maximum Columns In Table: 1024
- Maximum Column Name Length: 128 characters
- Maximum Row Size: 8060 bytes ( does not include LOB size )
ODBC (Client Version: 6.01.7601.17514)
LOB data must all be at the end of the select. If user enters a SQL statement that doesn't have them at the end of the statement they get an error, "This ODBC driver requires that all BLOB fields be at the end of the select.". A "select * from table" will move all the LOBs to the end.
