The optimizer may get more accurate estimates of selectivity if you can create histograms with a sufficiently large number of buckets You may also be able to work around some problems by creating function-based indexes that restate the data in the correct type if you can also change the SQL to match Applications that use special values instead of nulls in columns are liable to produce poor execution plans if the columns are used in range-based predicates Again, a histogram on the critical column may make an enormous difference Applying functions to columns that do not participate in function-based indexes can lead to some unexpected selectivities You may even find that restating the same clause in a different way can lead to a significant change in selectivity because of some of the inconsistencies of the fixed constants used for the selectivity in these cases. vb.net qr code reader Packages matching Tags:"QRCode" - NuGet Gallery

In this chapter, we ve looked at the difference between programming in classic C++ vs. managed code. We looked at Microsoft s Visual C++ 2005 and in particular the compilation modes available with Visual C++ 2005, including /clr:pure, /clr:safe, /clr:oldSyntax, /clr, and none of the above. We briefly discussed how to target 64-bit architectures with Visual C++ 2005. You also learned what an assembly is, looked at how to build one, examined what s in an assembly, saw how to reference other assemblies in a C++/CLI program, including how to control access to types in other assemblies, and briefly looked at the difference between the linker and the assembly linker. You also briefly saw some of what else there is to know about working with assemblies. There is much more that can be learned about assemblies in the CLR, but you now have enough for the purposes of working through the rest of this book. In the next chapter, you ll learn about objects and their semantics. open source qr code reader vb.net zxing/zxing: ZXing ("Zebra Crossing") barcode scanning ... - GitHub

Transitive closure can create and lose predicates for you, and generally the impact will be good Occasionally, the side effects can be catastrophic, sometimes they may simply be surprising Although people sometimes insist on avoiding referential integrity constraints on data warehouses because of the overheads, remember that constraints may help the optimizer find a better execution plan And don t be surprised when Oracle picks up a constraint, turns it into a predicate, and then migrates it through transitive closure to a different table.. Open your Web browser and go to the download page at na.blackberry.com/eng/services/desktop/mac.jsp (see Figure 4-1). Fill out the required information on the download page and click to download the software. Simple script to show numeric representation of character strings Repeat of the preceding, using a multibyte character set Demonstration of cardinality problems due to incorrect data types Creates a simple function to calculate the numeric value used by the optimizer to represent a string Problems with zero-padded character strings used for sequence numbers defaults.sql discrete_01.sql sysdate_01.sql like_test.sql fun_sel.sql dependent.sql trans_close_01.sql trans_close_02.sql trans_close_03.sql constraint_01.sql constraint_02.sql constraint_03.sql discrete_02.sql discrete_01a.sql discrete_02a.sql char_value.sql trans_close_02a.sql trans_close_03a.sql setenv.sql his chapter gets back into the language itself and covers how objects behave in C++/CLI. You ll learn a bit more about value types and reference types, including some of the implications of having a unified type system. You ll also see how to work with objects on the managed heap as though they were automatic variables, complete with the assurance that they will be cleaned up when they go out of scope. You ll look at tracking references and object dereferencing and copying. You ll also explore the various methods of passing parameters in C++/CLI and look at how to use C++/CLI types as return values. Once the file is downloaded, you will see a screen (see Figure 4-2).
