Sql_select return values

I created a scheme where i tryed to show some data from database and it crashed on sql_select. I found, that it was caused by that return type have no data.
I want to ask u when after sql_select comes ERROR_NO_DATA ?

Hello,
I am not sure I understand you problem. Did SQL_SELECT returned error code _ERR_NO_DATA (22) ? If so, no data could be read from the database.
More detailed error messages may be found in Trace directory (see the D2000 DBManager - debugging section in online manual.
Or was there a crash of DbManager process during SQL_SELECT? If so, please provide us with the log of Dbmanager (it can be found in Log directory).
