  - 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:
    
    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.
    Mappings for Types.TIMESTAMP and Types.TIMESTAMP_WITH_TIMEZONE should support explicit specification of precision if possible.
    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.
    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.

```
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.

    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:

```
public String currentTimestampWithTimeZone()
```
    Description copied from class: Dialect

    Overrides:
    
    currentTimestampWithTimeZone in class Dialect
  - extractPattern
```
public String extractPattern(TemporalUnit unit)
```
    The extract() function returns TemporalUnit.DAY_OF_WEEK numbered from 0 to 6. This isn't consistent with what most other databases do, so here we adjust the result by generating (extract(dow,arg)+1)).

public long getFractionalSecondPrecisionInNanos()
```
    microsecond is the smallest unit for an interval, and the highest precision for a timestamp, so we could use it as the "native" precision, but it's more convenient to use whole seconds (with the fractional part), since we want to use extract(epoch from ...) in our emulation of timestampdiff().
    
    Overrides:
    
    getFractionalSecondPrecisionInNanos in class Dialect
    
    Returns:
    
    the precision, specified as a quantity of nanoseconds

```
public void initializeFunctionRegistry(FunctionContributions functionContributions)
```
    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])
    
    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)
    
    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:

  - supportsMinMaxOnUuid
```
protected boolean supportsMinMaxOnUuid()
```

  - 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:
    
    a "static" delegate based on the JDBC4-defined SQLException hierarchy, and
    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

    Returns:
    
    true, but only because we can "batch" truncate
  - rowId
```
public String rowId(String rowId)
```
    Description copied from class: Dialect
    
    The name of a rowid-like pseudo-column which acts as a high-performance row locator, or null if this dialect has no such pseudo-column.
    If the rowid-like value is an explicitly-declared named column instead of an implicit pseudo-column, and if the given name is nonempty, return the given name.
    
    Overrides:
    
    rowId in class Dialect
    
    Parameters:
    
    rowId - the name specified by RowId.value(), which is ignored if Dialect.getRowIdColumnString(java.lang.String) is not overridden
  - rowIdSqlType
```
public int rowIdSqlType()
```
    Description copied from class: Dialect
    
    The JDBC type code of the rowid-like pseudo-column which acts as a high-performance row locator.
    
    Overrides:
    
    rowIdSqlType in class Dialect
    
    Returns:
    
    Types.ROWID by default
  - createOptionalTableUpdateOperation
```
public MutationOperation createOptionalTableUpdateOperation(EntityMutationTarget mutationTarget,
                                                            OptionalTableUpdate optionalTableUpdate,

```
public ParameterMarkerStrategy getNativeParameterMarkerStrategy()
```
    Description copied from class: Dialect
    
    Support for native parameter markers.
    This is generally dependent on both the database and the driver.
    
    Overrides:
    
    getNativeParameterMarkerStrategy in class Dialect
    
    Returns:
    
    May return null to indicate that the JDBC standard strategy should be used
