[SOLVED] Problem with Oracle CLOB Field
«
on:
August 23, 2016, 12:10:05 am »
Hi.
I'm using TOracleConnection to connect to an Oracle DB 11. I'm trying to make a select on a table with CLOB field, but is not working. The Lazarus freezes when trying to run select . Fields BLOB or CLOB are supported by TOracleConnection?

Yes , at least partial support is there.
But AFAIK there is no routine testing with Oracle so there may be some problems ...

A few months ago i tried to select oracle geometry field with sqldb and zeos query. Both let lazarus crash. So if you find a way to select clob or blob fields i would like to know it.

i got the trunc version of zeos 7.3. It does not compile with lazarus 1.6 (32 bit).
the error message is: ZPlainDriver.pas(268,35) Error: Identifier not found "ZOSCodePage"
to early.
It works, i compiled the packages in the wrong order.

i do not have a clob or blob field but i have a geometry field in Oracle. Zoes 7.3 still does not like these fields.
the error is:
OCI_ERROR: ORA-22307: operation must be on a user-defined type
are there plans to implement this in ZEOS?

How did you solve it? I still get the error "operation must be on a user-defined type" when i select an Oracle geometry field.
