When executing this unit test which creates a table with 500 fields an exception is generated when executing a select command for all fields.

[Test]
public void MaxFieldsTest()
{
FbCommand command;
FbDataReader reader;
System.Text.StringBuilder sb = new System.Text.StringBuilder();

sb\.AppendLine\("CREATE TABLE TEST\_MAX\_FIELDS \("\);
for \(int i = 0; i < 499; i\+\+\)
\{
	sb\.AppendLine\("FIELD\_" \+ i\.ToString\("D3"\) \+ " INTEGER,"\);
\}
sb\.AppendLine\("FIELD\_499 INTEGER\)"\);

command = new FbCommand\(sb\.ToString\(\), this\.Connection\);
command\.ExecuteNonQuery\(\);
command\.Dispose\(\);

command = new FbCommand\("SELECT \* FROM TEST\_MAX\_FIELDS", this\.Connection\);
reader = command\.ExecuteReader\(\);
reader\.Close\(\);
