• SQL Server Lookup Transformation Join Column Types

  Does anyone have a clue as to why DT_R4, DT_R8 are not allowed as join columns This means I cannot join tables on AccountNumbers, InvoiceNumbers, etc. What a pain... We didn't include support for floating point joins, because of the inherent inability of computers to accurately compare two floating point numbers. To make the comparisons consistent, we would need to introduce some sort of rounding and user specified precision. If we did not, you may might be now posting a question about why 1.75 is not equal to 1.75 J I hardly every see people store invoice or account numbers as floating point, I would be interested to know why you made this choice. ...Show All

• Visual FoxPro How to copy one column to another

  Hi all, I would like to copy a column that has prices (fprice) for parts in it to another column within the same table.  Then I am going to do a replace on the original column (fprice) to increase the price by a fixed amount (I know how to do that).  The table has a column that is not used for anything (by us) within the application.  It is a User Character 3 field (fcusrchr3).  I need to do this so our CFO can look back at the old pricing if need be.  Any help copying the column would be greatly appreciated.  FYI, this is in Visual Foxpro 6. Thanks, Erik FYI scope clause "ALL" that is found in many commands like replace,delete etc are an easy way ...Show All

• Visual C++ Extremely memory efficient file sort?

  Hello, We need a C function to sort files that are up to 10,000 rows long with 100 bytes per row (1MB), but only have 10KB of memory available to do so (this is an old 16 bit application ... we have over 500K lines of 16 bit code, so upgrading to 32 bit is not an option right now). At most, we can store about 90 of the 10,000 rows in memory at any one time, and the routine needs to be reasonably fast. Previously we had used a very small footprint database to do the sort, but recently had to scrap it since it maxed out at 16KB of memory and our newest upgrade reduced the space available for sorting to 10KB. Any thoughts on the best way to accomplish this Maybe the following articles and samples can help you: ...Show All
