Use ADO recordset GetString method. Recordset is available from TADODataSet.Recordset. Below there is description from MSDN: GetString Method Returns the Recordset as a string. Syntax Variant = recordset.GetString(StringFormat, NumRows, ColumnDelimiter, RowDelimiter, NullExpr)Return Value Returns the Recordset as a string-valued Variant (BSTR). Parameters StringFormat A StringFormatEnum value that specifies how the Recordset should be converted to a string. The RowDelimiter, ColumnDelimiter, and NullExpr parameters are used only with a StringFormat of adClipString. NumRows Optional. The number of rows to be converted in the Recordset. If NumRows is not specified, or if it is greater than the total number of rows in the Recordset, then all the rows in the Recordset are converted. ColumnDelimiter Optional. A delimiter used between columns, if specified, otherwise the TAB character. RowDelimiter Optional. A delimiter used between rows, if specified, otherwise the CARRIAGE RETURN character. NullExpr Optional. An expression used in place of a null value, if specified, otherwise the empty string. Remarks Row data, but no schema data, is saved to the string. Therefore, a Recordset cannot be reopened using this string. This method is equivalent to the RDO GetClipString method. //------------------------------------------ Regards, Vassiliev V.
