I have next table in two databases:
CREATE TABLE TABLE2(
ID INTEGER NOT NULL,
FIELD1 VARCHAR(256),
FIELD2 VARCHAR(256),
FIELD3 VARCHAR(512),
FIELD4 VARCHAR(100),
FIELD5 VARCHAR(2048))
Using EF I'm trying to copy data from one database to another. I want
to copy full data including Ids, so I disabled Identity Generation for
a destination database.
Problem is the next when EF generates insert it looks like the following:
"INSERT INTO \"TABLE2\"(\"ID\", \"FIELD1\", \"FIELD2\", \"FIELD3\",
\"FIELD4\", \"FIELD5\")\r\nVALUES (@p0, @p1, @p2, @p3, @p4, @p5,
NULL)\r\n"
And I have a problem here, parameters for these fields are treated
like SQL_TEXT and it tries to put UTF8 byte array to VARCHAR fields,
which is wrong. And a query fails on some long strings that in utf8
interpretation longer than 256 for example.
When I turn Identity Generation on, query looks like following:
EXECUTE BLOCK (
p1 BLOB SUB_TYPE TEXT = @p1, p7 BLOB SUB_TYPE TEXT = @p7, p8 BLOB
SUB_TYPE TEXT = @p8, p9 BLOB SUB_TYPE TEXT = @p9
) RETURNS (
"ID" INT)
AS BEGIN
INSERT INTO "TABLE2"("FIELD2", "FIELD3", "FIELD4", "FIELD5", "FIELD6")
VALUES (:p1, :p7, :p8, :p9, NULL)
RETURNING "ID" INTO :"ID";
SUSPEND;
END
And it doesn't fail.
