Why no record size mismatch error?

[Thomson, Martyn]

I see. So data written from the buffer to the table will be truncated losing the last character, with no warning.

To answer Lorri’s question: yes, the fields were also increased in length in the PH Dictionary.

PowerHouse gets its schema information from the database. If you change a column, and it’s still consistent with what PowerHouse had, then there’s no error. PowerHouse writes and updates by column, not by row/record as for indexed files. Just because the column buffer is now shorter than the column in the database doesn’t cause an error for a character field.

Hi Martin,

I gather the domain was changed in RDB, but, were the two fields affected changed in the PH dictionary?

When the QTP program updates the RDB table, do all 10 characters get updated or perhaps just 9 of 10?

Thanx

I increased the size of a domain from 9 to 10 chars. 2 fields use the domain and appear in 440+ tables.

Why does a QTP procedure not recompiled in years still work? It’s accessing one of said tables and a view of another. Surely it should generate a runtime error?
