Btrieve Error 22

Btrieve Error 22

(OP)
In Pervasive 10.3 my INSERT script gives error

Pervasive.Data.SqlClient.Lna.k: [LNA][Pervasive][ODBC Engine Interface][Data Record Manager]The data buffer parameter is too short(Btrieve Error 22)

How do I fix this ?

RE: Btrieve Error 22

Sounds like your DDFs may not match the data file. Are the data files / DDFs from a third party application? If so, make sure the DDFs are correct and accurately describe the data files.
The status 22 is caused when a buffer specified is smaller than the Engine expects. If a field in the DDF is defined as a 100 byte character field but the Btrieve file defines a record of less than 100 bytes, the status 22 can occur.

RE: Btrieve Error 22

You only have to specify values for fields that are defined "NOT NULL".
You can use the "Check Database" function in the DDF Builder tool to check the database. Here's a link to docs for v11 but they should apply for v10 too:
