A framework for defining database-specific SQL functions that are available via the dialect.
| SQLFunction | Provides support routines for the HQL functions as used in the various SQL Dialects Provides an interface for supporting various HQL functions that are translated to SQL. |
| AbstractAnsiTrimEmulationFunction | A SQLFunction providing support for implementing TRIM functionality
(as defined by both the ANSI SQL and JPA specs) in cases where the dialect may not support the full trim
function itself. |
| AnsiTrimEmulationFunction | A SQLFunction implementation that emulates the ANSI SQL trim function
on dialects which do not support the full definition. |
| AnsiTrimFunction | Defines support for rendering according to ANSI SQL TRIM function specification. |
| AvgWithArgumentCastFunction | Some databases strictly return the type of the of the aggregation value for AVG which is problematic in the case of averaging integers because the decimals will be dropped. |
| CastFunction | ANSI-SQL style cast(foo as type) where the type is a Hibernate type |
| CharIndexFunction | Emulation of locate() on Sybase |
| ClassicAvgFunction | Classic AVG sqlfunction that return types as it was done in Hibernate 3.1 |
| ClassicCountFunction | Classic COUNT sqlfunction that return types as it was done in Hibernate 3.1 |
| ClassicSumFunction | Classic SUM sqlfunction that return types as it was done in Hibernate 3.1 |
| ConditionalParenthesisFunction | Essentially the same as StandardSQLFunction,
except that here the parentheses are not included when no arguments are given. |
| ConvertFunction | A Caché defintion of a convert function. |
| DerbyConcatFunction | A specialized concat() function definition in which:
|
| NoArgSQLFunction | A function which takes no arguments |
| NvlFunction | Emulation of coalesce() on Oracle, using multiple nvl() calls |
| PositionSubstringFunction | Emulation of locate() on PostgreSQL |
| SQLFunctionRegistry | |
| SQLFunctionTemplate | Represents HQL functions that can have different representations in different SQL dialects. |
| StandardAnsiSqlAggregationFunctions | TODO : javadoc |
| StandardAnsiSqlAggregationFunctions.AvgFunction | Definition of a standard ANSI SQL compliant AVG function |
| StandardAnsiSqlAggregationFunctions.CountFunction | Definition of a standard ANSI SQL compliant COUNT function |
| StandardAnsiSqlAggregationFunctions.MaxFunction | |
| StandardAnsiSqlAggregationFunctions.MinFunction | |
| StandardAnsiSqlAggregationFunctions.SumFunction | |
| StandardJDBCEscapeFunction | Analogous to StandardSQLFunction
except that standard JDBC escape sequences (i.e. |
| StandardSQLFunction | Provides a standard implementation that supports the majority of the HQL functions that are translated to SQL. |
| TemplateRenderer | Delegate for handling function "templates". |
| TrimFunctionTemplate | Defines the basic template support for TRIM functions |
| TrimFunctionTemplate.Options | |
| TrimFunctionTemplate.Specification | |
| VarArgsSQLFunction | Support for slightly more general templating than StandardSQLFunction, with an unlimited number of arguments. |
