Hello,

I'm running Firebird 2.1 SS on Windows XP Prof. SP3.
Using Firebird to load huge data (around 80GB at this time) and now I
used global temporary table to generate some new data. I ran query (in
fact its a block) to fill that GTT (its name is TMP_COBEC) and then I
tried to update some records. But after update of few hundred records I
get error mentioned in %subject%.

GTT table TMP_COBEC's DDL (character set UTF8 is used):

CREATE GLOBAL TEMPORARY TABLE TMP_COBEC (
ID_NAMEDPLC BIGINT,
AREA_ID BIGINT NOT NULL,
POI_ID BIGINT NOT NULL,
LANG_CODE VARCHAR(3) NOT NULL,
DESCRIPTION VARCHAR(255) NOT NULL,
DESCRIPTION_TR VARCHAR(255) NOT NULL,
COKRES_AREA_ID BIGINT NOT NULL,
ID_CCOUNTRY VARCHAR(3) NOT NULL,
GEOMETRY_POINT BLOB SUB_TYPE 0 SEGMENT SIZE 80,
GEOMETRY_POLY_CITY BLOB SUB_TYPE 0 SEGMENT SIZE 80,
GEOMETRY_POLY_SETTLEMENT BLOB SUB_TYPE 0 SEGMENT SIZE 80,
PRIORITY BIGINT NOT NULL,
SRC VARCHAR(3) NOT NULL,
NAME_TYPE VARCHAR(1) NOT NULL,
CITY_AREA_ID BIGINT,
SETTLEMENT_AREA_ID BIGINT
) ON COMMIT DELETE ROWS;

CREATE INDEX IX_TMP_COBEC_NT_AREA ON TMP_COBEC (NAME_TYPE, AREA_ID);
CREATE INDEX IX_TMP_COBEC_NT_POI ON TMP_COBEC (NAME_TYPE, POI_ID);
CREATE INDEX IX_TMP_COBEC_SRC_POI ON TMP_COBEC (SRC, POI_ID);



I ran this block when I get that error:

END
END

I tried to UTG, but unsuccessfull. Can anybody give me an advice?

Thanks
