Unknown type JDBC Type 2004
Hi all!
Tell me please what I need to configure in my own external table to save BLOB?
Table columns is
ID (Autoincrement), DEALID, MESSAGECODE, PZPVSTREAM, CREATEDDATETIME (Current timestamp), PZINSKEY
Steps of my activity is
1) Page-New create page of class that map to table
2) Property-Set
a. .DealID = "AA-123" (This field is exposed)
b. .MessageCode = "121" (This field is exposed)
c. .MessageBody = "My test message" (This field is not exposed)
3) Obj-Save with Write now option
And on the third step I get an error "Database column MessageBody in database pegadata, table PRPC.TEMPTABLE has an unknown type: JDBC Type 2004".
I think that all exposed properties saved separately and all of other properties goes to BLOB column named PZPVSTREAM, but I was wrong...
Also can you tell me how I can read data from this field?
Thanks in advance!
