DB2 CONNECT / DB2CONNCT / 970 - DB2

If you have a .NET application that is using ParameterName in 
your query to update (or insert) a clob > 32K and another 
column, 
you might encounter a data corruption because the command 
paramaters 
are processed in incorrect order. 
 
The following example will insert "CLOBTEST" in cclob column and 
"Some long CLOB value padded...." in the column col2 when we 
expect the opposite. 
 
string clobValue = "Some long CLOB value padded with '-' to 
33,000 characters".PadRight(33000, '-'); 
using (var conn = new DB2Connection(bld.ConnectionString)) 
{ 
var update = new DB2Command(string.Format("UPDATE tab1 SET 
cclob=@CCLOB, col2=@COL2 WHERE col1 ='{0}' ",col1Value), conn); 
 
var col2 = update.Parameters.Add("@COL2", DB2Type.Char); 
var cclob = update.Parameters.Add("@CCLOB", DB2Type.Clob); 
 
cclob.Value = clobValue; 
col2.Value = "CLOBTEST"; 
conn.Open(); 
update.ExecuteNonQuery(); 
}
