RE: [UV] Very slow SQL query
César, So the problem is not joins or indices. So it must be somewhere else :-) 1. If you use a SORT command, is that as slow? SORT CCMLIAL BY EMP BY ALBA BY NUMLIN WITH EMPABLA = "1*05236" PEDIDO REFART DESART CANDIDAD CANTMODALB NOPAGE 2. If it is, what are these fields doing? Are they Data fields or I Descriptors? Do any call BASIC subroutines, or do translates (TRANS or XLATE functions?) 3. The obvious one - what is the file sizing like? 4. What does the BASIC program do that is different? There should be no reason for this SQL command to be slow.
