方法详细资料

renderTransformerReadFragment

public static String renderTransformerReadFragment(String fragment,
                                                   String... columnNames)

renderWhereStringTemplate

public static String renderWhereStringTemplate(String sqlWhereString,
                                               Dialect dialect,
                                               SQLFunctionRegistry functionRegistry)

renderWhereStringTemplate

@Deprecated
public static String renderWhereStringTemplate(String sqlWhereString,
                                               String placeholder,
                                               Dialect dialect)

已过时。

Only intended for annotations usage; use renderWhereStringTemplate(String, String, Dialect, SQLFunctionRegistry) instead

Same functionality as renderWhereStringTemplate(String, String, Dialect, SQLFunctionRegistry), except that a SQLFunctionRegistry is not provided (i.e., only the dialect-defined functions are considered). This is only intended for use by the annotations project until the many-to-many/map-key-from-target-table feature is pulled into core.

renderWhereStringTemplate

public static String renderWhereStringTemplate(String sqlWhereString,
                                               String placeholder,
                                               Dialect dialect,
                                               SQLFunctionRegistry functionRegistry)

Takes the where condition provided in the mapping attribute and interpolates the alias. Handles sub-selects, quoted identifiers, quoted strings, expressions, SQL functions, named parameters.

参数:

sqlWhereString - The string into which to interpolate the placeholder value

placeholder - The value to be interpolated into the the sqlWhereString

dialect - The dialect to apply

functionRegistry - The registry of all sql functions

返回:

The rendered sql fragment

renderOrderByStringTemplate

@Deprecated
public static String renderOrderByStringTemplate(String orderByFragment,
                                                 Dialect dialect,
                                                 SQLFunctionRegistry functionRegistry)

已过时。

Use translateOrderBy(java.lang.String, org.hibernate.sql.ordering.antlr.ColumnMapper, org.hibernate.engine.spi.SessionFactoryImplementor, org.hibernate.dialect.Dialect, org.hibernate.dialect.function.SQLFunctionRegistry) instead

Performs order-by template rendering without column mapping. An ORDER BY template has all column references "qualified" with a placeholder identified by TEMPLATE

参数:

orderByFragment - The order-by fragment to render.

dialect - The SQL dialect being used.

functionRegistry - The SQL function registry

返回:

The rendered ORDER BY template.

renderOrderByStringTemplate

public static String renderOrderByStringTemplate(String orderByFragment,
                                                 ColumnMapper columnMapper,
                                                 SessionFactoryImplementor sessionFactory,
                                                 Dialect dialect,
                                                 SQLFunctionRegistry functionRegistry)

translateOrderBy

public static OrderByTranslation translateOrderBy(String orderByFragment,
                                                  ColumnMapper columnMapper,
                                                  SessionFactoryImplementor sessionFactory,
                                                  Dialect dialect,
                                                  SQLFunctionRegistry functionRegistry)

Performs order-by template rendering allowing column mapping. An ORDER BY template has all column references "qualified" with a placeholder identified by TEMPLATE which can later be used to easily inject the SQL alias.

参数:

orderByFragment - The order-by fragment to render.

columnMapper - The column mapping strategy to use.

sessionFactory - The session factory.

dialect - The SQL dialect being used.

functionRegistry - The SQL function registry

返回:

The rendered ORDER BY template.
