Uses of AbstractSqmFunctionDescriptor in org.hibernate.dialect.function

Subclasses of AbstractSqmFunctionDescriptor in org.hibernate.dialect.function

Modifier and Type	Class	Description
class	AvgFunction
class	CaseLeastGreatestEmulation	Some databases don't have a function like least() or greatest(), and on those platforms we emulate the function using case.
class	CastFunction	ANSI SQL-inspired cast() function, where the target types are enumerated by CastType, and portability is achieved by delegating to Dialect.castPattern(CastType, CastType).
class	CastingConcatFunction
class	CastStrEmulation	The HQL str() function is now considered a synonym for cast(x as String).
class	ChrLiteralEmulation	A chr implementation that translates integer literals to string literals.
class	CoalesceIfnullEmulation
class	ConcatPipeFunction	A concat function with a pattern for clob arguments.
class	CountFunction
class	CurrentFunction	A "function" with no parameters that returns the current date, time, or timestamp.
class	DateTruncEmulation	Emulation of trunc(datetime, temporal_unit) function that leverages formatting the datetime to string and back to truncate it
class	DB2FormatEmulation	DB2's varchar_format() can't handle quoted literal strings in the format pattern.
class	DB2PositionFunction	DB2's position() function always requires a code unit before version 11.
class	DB2SubstringFunction	DB2's substring() function requires a code unit and substr() can't optionally take it, so we render substr() by default.
class	DerbyLpadEmulation	A derby implementation for lpad.
class	DerbyRpadEmulation	A derby implementation for rpad.
class	EveryAnyEmulation	Most databases don't have a function like every() or any().
class	ExtractFunction	ANSI SQL-inspired extract() function, where the date/time fields are enumerated by TemporalUnit, and portability is achieved by delegating to Dialect.extractPattern(TemporalUnit).
class	FormatFunction	A format function with support for composite temporal expressions.
class	HypotheticalSetFunction
class	HypotheticalSetWindowEmulation
class	InsertSubstringOverlayEmulation	Emulates the ANSI SQL-standard overlay() function using insert() substring(), and concat().
class	IntegralTimestampaddFunction	Used in place of TimestampaddFunction for databases which don't support fractional seconds in the timestampadd() function.
class	InverseDistributionFunction
class	InverseDistributionWindowEmulation
class	LengthFunction	A length function with separate patterns for string and clob argument.
class	ListaggFunction
class	ListaggGroupConcatEmulation
class	ListaggStringAggEmulation
class	LocatePositionEmulation	Emulates the ANSI SQL-standard position() function using locate().
class	LpadRpadPadEmulation	HQL function inspired by the ANSI SQL trim function, with a funny syntax involving a TrimSpec.
class	MinMaxCaseEveryAnyEmulation	Most databases don't have a function like every() or any().
class	ModeStatsModeEmulation
class	NvlCoalesceEmulation	Oracle 8i had no coalesce() function, so we emulate it using chained nvl()s.
class	OracleTruncFunction	Custom TruncFunction for Oracle which uses emulation when truncating datetimes to seconds
class	PostgreSQLMinMaxFunction	PostgreSQL doesn't support min/max for uuid yet, but since that type is comparable we want to support this operation.
class	PostgreSQLTruncFunction	Custom TruncFunction for PostgreSQL which uses the dialect-specific function for numeric truncation
class	PostgreSQLTruncRoundFunction	PostgreSQL only supports the two-argument trunc and round functions with the following signatures: trunc(numeric, integer) round(numeric, integer)
class	QuantifiedLeastGreatestEmulation
class	SqlFunction	A function to pass through a SQL fragment.
class	SqlServerConvertTruncFunction	Custom TruncFunction for SQL Server versions < 16 which uses the custom SqlServerConvertTruncFunction.DateTruncConvertEmulation
class	SQLServerEveryAnyEmulation	SQL Server doesn't have a function like every() or any().
class	SQLServerFormatEmulation	SQL Server behaves strangely when the first argument to format is of the type time, so we cast to datetime.
class	StandardSQLFunction	Simplified API allowing users to contribute SqmFunctionDescriptors to HQL.
class	SybaseTruncFunction	Custom TruncFunction for Sybase which uses a dialect-specific emulation function for datetimes
class	TimestampaddFunction	The timestampadd() or dateadd() function has a funny syntax which accepts a TemporalUnit as the first argument, and the actual set of accepted units varies widely.
class	TimestampdiffFunction	The timestampdiff() or datediff() function has a funny syntax which accepts a TemporalUnit as the first argument, and the actual set of accepted units varies widely.
class	TransactSQLStrFunction	A special function that renders a T-SQL str() function if more than a single argument is given, or otherwise renders a cast() expression just like CastStrEmulation.
class	TrimFunction	ANSI SQL-standard trim() function, which has a funny syntax involving a TrimSpec, and portability is achieved using Dialect.trimPattern(TrimSpec, char).
class	TruncFunction	Custom function that manages both numeric and datetime truncation

Subclasses of AbstractSqmFunctionDescriptor in org.hibernate.query.sqm.function

Modifier and Type	Class	Description
class	AbstractSqmSelfRenderingFunctionDescriptor
class	JdbcEscapeFunctionDescriptor	Acts as a wrapper to another SqmFunctionDescriptor, rendering the standard JDBC escape sequence {fn f(x, y)} around the invocation syntax generated by its delegate.
class	MultipatternSqmFunctionDescriptor	Support for overloaded functions defined in terms of a list of patterns, one for each possible function arity.
class	NamedSqmFunctionDescriptor	Provides a standard implementation that supports the majority of the HQL functions that are translated to SQL.
class	PatternBasedSqmFunctionDescriptor	Support for HQL functions that have different representations in different SQL dialects, where the difference can be handled via a pattern template.
