Hello!
Peter, i take in response your wishes and encoded this email by UTF-8 :)
I create table:
CREATE TABLE "test" (
"unicode_fss" VARCHAR(5) CHARACTER SET UNICODE_FSS,
"win1251" VARCHAR(5) CHARACTER SET WIN1251
);
Then i try execute code:
string sql = "insert into \"test\" (\"unicode_fss\", \"win1251\") values
(@unicodeValue, @win1251)";
FbCommand unicode_insert = new FbCommand(sql, connection, transaction);
unicode_insert.Parameters.Add("@unicodeValue", FbDbType.VarChar).Value =
"ÞÔÏÔÏ"; // string length = 5
unicode_insert.Parameters.Add("@win1251", FbDbType.VarChar).Value = "ÞÔÏÔÏ";
// string length = 5
unicode_insert.ExecuteNonQuery(); // Exception HERE!!!
Exception:
An unhandled exception of type 'System.InvalidOperationException' occurred
in firebirdsql.data.firebird.dll
Additional information: Invalid length of 10 bytes, max length allowed 5
bytes, for parameter @win1251 index 1
Why i can't post russian string with length 5 in field varchar(5)??? I know
what russian char takes 2 bytes, but i thinking when i create varchar(5) -
it means i can post in this field 5 char (independently of charset). When i
use unicode_fss - all fine...
Thanks.
P.S. I attached full source code sample.
