Priority: Critical
Exception when using Guid variables.
When performing the same procedure in four different commands, two of them give
out an exception.
1)Executing this work fine.
comm.CommandText = String.Format("select * from
SCOPEINFO_SP_UPD({0},{1},{2},{3},{4},{5})"
, "@sync_scope_knowledge"
, "@sync_scope_id"
, "@sync_scope_cleanup_knowledge"
, "@sync_scope_name"
, "@sync_check_concurrency"
, "@sync_scope_timestamp");
2)Executing this work fine.
comm.CommandText = String.Format("execute procedure
SCOPEINFO_SP_UPD {0},{1},{2},{3},{4},{5};"
, "@sync_scope_knowledge"
, "@sync_scope_id"
, "@sync_scope_cleanup_knowledge"
, "@sync_scope_name"
, "@sync_check_concurrency"
, "@sync_scope_timestamp");
3)give out an exception
comm.CommandType = CommandType.StoredProcedure;
comm.CommandText = "SCOPEINFO_SP_UPD";
comm.Parameters["sync_scope_id"].Value =
Guid.Parse("31313131-3131-3131-3131-313131313131");
in test class: BugV1_1();
exception:
Dynamic SQL Error
SQL error code = -303
arithmetic exception, numeric overflow, or string truncation
numeric value is out of range
4)give out an exception
comm.CommandType = CommandType.StoredProcedure;
comm.CommandText = "SCOPEINFO_SP_UPD";
comm.Parameters["sync_scope_id"].Value = Guid.NewGuid();
in test class: BugV1_2();
exception:
Dynamic SQL Error
SQL error code = -303
conversion error from string "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
