Hi everyone, Some good news for you among all the gloom of these virus-ridden times: Nine, Subz and Danyfirex have accepted the invitation to become MVPs. Please join me in congratulating them on their new status in our community. Keep safe out there, M23

In the thread above a few people hit on the idea of synthesizing a separate column to be indexed, named like Date_and_Name-Sequence-Number. I see how this could improve the sort time on a large set of Selected records. The problem is the potential (read: likelihood) that the fake-indexed column will become wrong/out of date as compared with the real data. As in, you have introduced a new data-integrity nightmare. That manual column now must be maintained across all rows having that Date / in that Sequence. Whenever the Date column is inserted or updated in any row having that Date, the entire set of records with that Date must be re-sequenced, or at least checked for the need to re-sequence. I can't believe there is no way to index the Date and Name columns to get the required sort performance, regardless of what database engine we're talking about. However! I understand some bigger client-server SQL engines have this kind of feature built in. A 'virtual' column can be defined at the table level, where a synthesized column returns the result of an expression that evaluates other columns in that row. In this way, the column is kind of like a View, except it's at the Column level instead of at the Table level. This may or may not solve the slow-sort problem, but it would certainly avoid introducing a foreseeable data integrity problem. Another exception would be the enterprise-level case where there are two sets of tables: one set optimized for normalization/efficient storage focused on integrity, and one set optimized for fast selecting and sorting for output purposes. One tradeoff is data staleness: your output is only as fresh as your periodic publish process, where the data is copied and de-normalized from the Storage database to the Reporting tables/database. From experience at this level of IT, we always had a third set of tables too, which were optimized for input: zero normalization, with intake processing to reject invalid data.

I miss bars.

Please use this Support thread for your questions. Thanks

Hi, i was just playing with this, searching for the solution. Then i saw your workaround, and then it clicked ! If you change the $iBuffer = StringLen($sMessage) + 1 and remove the +1, it should work. (from your 1st post) Logical explanation: Looks like the cmd is waiting for data, but got nothing, because the string length was too short.

Hi Faustf, Thank you very much. This worked.
