SQLite实现了SQL的Window Functions特征,允许对行的子集(Subset、window)进行查询。通过分析含有Window函数的SELECT语句,SELECT语句就会使用sqlite3WindowRewrite函数进行转化。 src/select.c:5643 sqlite3SelectPrep(pParse, p, 0); ... #ifndef SQLITE_OMIT_WINDOWFUNC if( sqlite3WindowRewrite(pParse, p) ){ got...

窗口函数(WindowFunctions)中的Window子句用于指定计算的范围,即函数对哪些行进行操作。其默认范围取决于是否同时使用了PARTITION BY和ORDER BY子句。 当只有ORDER BY子句,没有PARTITION BY和Window子句时: 默认的Window范围是从整个结果集的第一行到当前行,即RANGE BETWEEN UNBOUNDED PRECEDING A ...
