How to get the DataType and Size of a column using the SqlDataReader?
Please use function GetTableSchema .
SqlDataReader reader= command.ExecuteReader();using (var schemaTable = reader.GetSchemaTable()) { foreach (DataRow row in schemaTable.Rows) { string ColumnName= row.Field<string>("ColumnName"); string DataTypeName= row.Field<string>("DataTypeName"); short NumericPrecision= row.Field<short>("NumericPrecision"); short NumericScale= row.Field<short>("NumericScale"); int ColumnSize= row.Field<int>("ColumnSize"); Console.WriteLine("Column: {0} Type: {1} Precision: {2} Scale: {3} ColumnSize {4}", ColumnName, DataTypeName, NumericPrecision, NumericScale, ColumnSize); } }Using Table schema , you can get all column related property using c# .
Thanks .
You can use GetDataTypeName() function to get the data type of the field
String dataType = reader.GetDataTypeName(FIELD_INDEX);
