set will be evaluated that way, but before applying the limit clause. So you might choose to either put all your project-specific plugins in a single common uber-library; or you might choose to have a separate library for every UDF and plugin; that is up to you. H like in the example, should be completely sufficient, too. Using reserved keywords as the names of variables and stored procedure parameters is not restricted. For most UDFs and plugins, a mere #include "sphinxudf. The following table lists SQL Server and SQL Data Warehouse reserved keywords. Multiple plugins (and/or UDFs) may reside in a single library file. These words do not constrain the minimum SQL grammar; however, to ensure compatibility with drivers that support the core SQL grammar, applications should avoid using these keywords.

However, the returned strings values are managed by Sphinx and we have our own allocator, so for the return values specifically, you need to use it too. Within your UDF, you must implement and export only a couple functions, literally. UDFs can receive arguments of pretty much any valid internal Sphinx type. In the last case you must use args- fn_malloc function to allocate the returned string values. We provide an example UDF library written in plain C and implementing several functions (demonstrating a few different techniques) along with our source code, see src/udfexample. The first argument, a pointer to SPH_UDF_init structure, is essentially a pointer to our function state. Note that while UDFs are first-class plugins they are nevertheless installed using a separate create function statement. External, procedure, aLL, fetch, public, alter, fILE. Testfunc is called for every eligible row (see above whenever Sphinx needs to compute the UDF value. Depending on how your UDFs are used in the query, the main function call (testfunc in our example) might be called in a rather different volume and order.
