Can anybody make a simple example how to insert and select binary data from table?
I'm interesting in Oracle, Postgres and sqlite.

Except for oracle, you just place SqlBinary into your insert

SQL * Insert(IMAGE)(ID, id)(BODY, SqlBinary(data));

As for Oracle, this works too, but is hindered by oracle maximum statement length limit, which is ~32000 - means you can store only about 15KB.

Another option is to use SqlRaw, but in that case you cannot use SqlExp:

SQL.Execute("insert IMAGE(ID, BODY) values (?, ?)", id, SqlRaw(data));

This should work for all dbs... Usually, it is also more effective, but at the same time less convenient Smile
