      Description copied from class: Dialect
      Initialize the given registry with any dialect-specific functions.

      Support for certain SQL functions is required, and if the database does not support a required function, then the dialect must define a way to emulate it.

      These required functions include the functions defined by the JPA query language specification:

      • avg(arg) - aggregate function
      • count([distinct ]arg) - aggregate function
      • max(arg) - aggregate function
      • min(arg) - aggregate function
      • sum(arg) - aggregate function
      • coalesce(arg0, arg1, ...)
      • nullif(arg0, arg1)
      • lower(arg)
      • upper(arg)
      • length(arg)
      • concat(arg0, arg1, ...)
      • locate(pattern, string[, start])
      • substring(string, start[, length])
      • trim([[spec ][character ]from] string)
      • abs(arg)
      • mod(arg0, arg1)
      • sqrt(arg)
      • current date
      • current time
      • current timestamp
      Along with an additional set of functions defined by ANSI SQL:
      • any(arg) - aggregate function
      • every(arg) - aggregate function
      • var_samp(arg) - aggregate function
      • var_pop(arg) - aggregate function
      • stddev_samp(arg) - aggregate function
      • stddev_pop(arg) - aggregate function
      • cast(arg as Type)
      • extract(field from arg)
      • ln(arg)
      • exp(arg)
      • power(arg0, arg1)
      • floor(arg)
      • ceiling(arg)
      • position(pattern in string)
      • substring(string from start[ for length])
      • overlay(string placing replacement from start[ for length])
      And the following functions for working with java.time types:
      • local date
      • local time
      • local datetime
      • offset datetime
      • instant
      And a number of additional "standard" functions:
      • left(string, length)
      • right(string, length)
      • replace(string, pattern, replacement)
      • pad(string with length spec[ character])
      • repeat(string, times)
      • pi
      • log10(arg)
      • log(base, arg)
      • sign(arg)
      • sin(arg)
      • cos(arg)
      • tan(arg)
      • asin(arg)
      • acos(arg)
      • atan(arg)
      • atan2(arg0, arg1)
      • round(arg0[, arg1])
      • truncate(arg0[, arg1])
      • sinh(arg)
      • tanh(arg)
      • cosh(arg)
      • least(arg0, arg1, ...)
      • greatest(arg0, arg1, ...)
      • degrees(arg)
      • radians(arg)
      • bitand(arg1, arg1)
      • bitor(arg1, arg1)
      • bitxor(arg1, arg1)
      • format(datetime as pattern)
      • collate(string as collation)
      • str(arg) - synonym of cast(a as String)
      • ifnull(arg0, arg1) - synonym of coalesce(a, b)
      Finally, the following functions are defined as abbreviations for extract(), and desugared by the parser:
      • second(arg) - synonym of extract(second from a)
      • minute(arg) - synonym of extract(minute from a)
      • hour(arg) - synonym of extract(hour from a)
      • day(arg) - synonym of extract(day from a)
      • month(arg) - synonym of extract(month from a)
      • year(arg) - synonym of extract(year from a)
      Note that according to this definition, the second() function returns a floating point value, contrary to the integer type returned by the native function with this name on many databases. Thus, we don't just naively map these HQL functions to the native SQL functions with the same names.
      Overrides:
      initializeFunctionRegistry in class Dialect

    • getMaximumSeriesSize

      protected int getMaximumSeriesSize()
      Oracle doesn't support the generate_series function or lateral recursive CTEs, so it has to be emulated with a top level recursive CTE which requires an upper bound on the amount of elements that the series can return.

      See Also:

    • currentDate

      public String currentDate()
      Description copied from class: Dialect
      Translation of the HQL/JPQL current_date function, which maps to the Java type Date, and of the HQL local_date function which maps to the Java type LocalDate.
      Overrides:
      currentDate in class Dialect

    • currentTime

      public String currentTime()
      Description copied from class: Dialect
      Translation of the HQL/JPQL current_time function, which maps to the Java type Time which is a time with no time zone. This contradicts ANSI SQL where current_time has the type TIME WITH TIME ZONE.

      It is recommended to override this in dialects for databases which support localtime or time at local.

      Overrides:
      currentTime in class Dialect

    • currentTimestamp

      public String currentTimestamp()
      Description copied from class: Dialect
      Translation of the HQL/JPQL current_timestamp function, which maps to the Java type Timestamp which is a datetime with no time zone. This contradicts ANSI SQL where current_timestamp has the type TIMESTAMP WITH TIME ZONE.

      It is recommended to override this in dialects for databases which support localtimestamp or timestamp at local.

      Overrides:
      currentTimestamp in class Dialect

    • currentLocalTime

      public String currentLocalTime()
      Description copied from class: Dialect
      Translation of the HQL local_time function, which maps to the Java type LocalTime which is a time with no time zone. It should usually be the same SQL function as for Dialect.currentTime().

      It is recommended to override this in dialects for databases which support localtime or current_time at local.

      Overrides:
      currentLocalTime in class Dialect

    • currentLocalTimestamp

      public String currentLocalTimestamp()
      Description copied from class: Dialect
      Translation of the HQL local_datetime function, which maps to the Java type LocalDateTime which is a datetime with no time zone. It should usually be the same SQL function as for Dialect.currentTimestamp().

      It is recommended to override this in dialects for databases which support localtimestamp or current_timestamp at local.

      Overrides:
      currentLocalTimestamp in class Dialect

    • currentTimestampWithTimeZone

      public String currentTimestampWithTimeZone()
      Description copied from class: Dialect
      Translation of the HQL offset_datetime function, which maps to the Java type OffsetDateTime which is a datetime with a time zone. This in principle correctly maps to the ANSI SQL current_timestamp which has the type TIMESTAMP WITH TIME ZONE.
      Overrides:
      currentTimestampWithTimeZone in class Dialect

    • supportsInsertReturningGeneratedKeys

      Description copied from class: Dialect
      Does this dialect fully support returning arbitrary generated column values after execution of an insert statement, using the JDBC method Connection.prepareStatement(String, String[]).

      Support for returning the generated value of an identity column via the JDBC method Connection.prepareStatement(String, int) is insufficient here.

      Overrides:
      supportsInsertReturningGeneratedKeys in class Dialect
      Returns:
      true if GetGeneratedKeysDelegate works for any sort of primary key column (not just identity columns), or false if GetGeneratedKeysDelegate does not work, or only works for specialized identity/"autoincrement" columns
      See Also:

    • castPattern

      public String castPattern(CastType from, CastType to)

      Returns:
      the precision, specified as a quantity of nanoseconds
      See Also:

    • extractPattern

      public String extractPattern(TemporalUnit unit)
      Oracle supports a limited list of temporal fields in the extract() function, but we can emulate some of them by using to_char() with a format string instead of extract().

      Thus, the additional supported fields are TemporalUnit.DAY_OF_YEAR, TemporalUnit.DAY_OF_MONTH, TemporalUnit.DAY_OF_YEAR, and TemporalUnit.WEEK.

      Overrides:
      extractPattern in class Dialect
      Parameters:

      Parameters:
      unit - The unit to add to the temporal
      temporalType - The type of the temporal
      intervalType - The type of interval to add or null if it's not a native interval

      Parameters:
      unit - the first argument
      fromTemporalType - true if the first argument is a timestamp, false if a date

    • columnType

      protected String columnType(int sqlTypeCode)
      Description copied from class: Dialect
      The database column type name for a given JDBC type code defined in Types or SqlTypes. This default implementation returns the ANSI-standard type name.

      This method may be overridden by concrete Dialects as an alternative to Dialect.registerColumnTypes(TypeContributions, ServiceRegistry) for simple registrations.

      Note that:

      1. Implementations of this method are expected to define a sensible mapping forTypes.NCLOB Types.NCHAR, and Types.NVARCHAR. On some database, these types are simply remapped to CLOB, CHAR, and VARCHAR.
      2. Mappings for Types.TIMESTAMP and Types.TIMESTAMP_WITH_TIMEZONE should support explicit specification of precision if possible.
      3. As specified by DdlTypeRegistry.getDescriptor(int), this method never receives Types.LONGVARCHAR, Types.LONGNVARCHAR, nor Types.LONGVARBINARY, which are considered synonyms for their non-LONG counterparts.
      4. On the other hand, the types SqlTypes.LONG32VARCHAR, SqlTypes.LONG32NVARCHAR, and SqlTypes.LONG32VARBINARY are not synonyms, and implementations of this method must define sensible mappings, for example to database-native TEXT or CLOB types.
      Overrides:
      columnType in class Dialect
      Parameters:
      sqlTypeCode - a SQL type code
      Returns:
      a column type name, with $l, $p, $s placeholders for length, precision, scale

    • buildSQLExceptionConversionDelegate

      public SQLExceptionConversionDelegate buildSQLExceptionConversionDelegate()
      Description copied from class: Dialect
      An instance of SQLExceptionConversionDelegate for interpreting dialect-specific error or SQLState codes.

      If this method is overridden to return a non-null value, the default SQLExceptionConverter will use the returned SQLExceptionConversionDelegate in addition to the following standard delegates:

      1. a "static" delegate based on the JDBC4-defined SQLException hierarchy, and
      2. a delegate that interprets SQLState codes as either X/Open or SQL-2003 codes, depending on what is reported by the JDBC driver.

      It is strongly recommended that every Dialect implementation override this method, since interpretation of a SQL error is much more accurate when based on the vendor-specific error code, rather than on the SQLState.

      Overrides:
      buildSQLExceptionConversionDelegate in class Dialect
      Returns:
      The SQLExceptionConversionDelegate for this dialect
