Nested Classes

Modifier and Type	Class	Description
static class	MockSqlOperatorTable.BadTableFunction	Another bad table function: declares itself as a table function but does not return CURSOR.
static class	MockSqlOperatorTable.CompareStringsOrNumericValues	"COMPARE_STRINGS_OR_NUMERIC_VALUES" is a user-defined function whose arguments can be either two strings or two numeric values of the same type.
static class	MockSqlOperatorTable.CompositeFunction	"COMPOSITE" user-defined scalar function.
static class	MockSqlOperatorTable.DedupFunction	"DEDUP" user-defined table function.
static class	MockSqlOperatorTable.DynamicTypeFunction	"DYNTYPE" user-defined table function.
static class	MockSqlOperatorTable.InvalidTableFunction	Invalid user-defined table function with multiple input tables with row semantics.
static class	MockSqlOperatorTable.MapFunction	"MAP" user-defined function.
static class	MockSqlOperatorTable.MyAggFunc	"MYAGGFUNC" user-defined aggregate function.
static class	MockSqlOperatorTable.MyAvgAggFunction	"MYAGG" user-defined aggregate function.
static class	MockSqlOperatorTable.MyFunction	"MYFUN" user-defined scalar function.
static class	MockSqlOperatorTable.NotATableFunction	Not valid as a table function, even though it returns CURSOR, because it does not implement SqlTableFunction.
static class	MockSqlOperatorTable.RampFunction	"RAMP" user-defined table function.

static class	MockSqlOperatorTable.ScoreTableFunction	"Score" user-defined table function.
static class	MockSqlOperatorTable.SimilarlityTableFunction	Similarity performs an analysis on two data sets, which are both tables of two columns, treated as the x and y axes of a graph.
static class	MockSqlOperatorTable.SplitFunction	"SPLIT" user-defined function.
static class	MockSqlOperatorTable.StructuredFunction	"STRUCTURED_FUNC" user-defined function whose return type is structured type.
