  - extractRealDialect
```
public static Dialect extractRealDialect(Dialect dialect)
```
    Extract the wrapped dialect, recursively until a non-wrapped implementation is found; this is useful for all the code needing to know "of which type" the underlying implementation actually is.
    
    Parameters:
    
    dialect - the Dialect to unwrap
    
    Returns:
    
    a Dialect implementation which is not a DialectDelegateWrapper; could be the same as the argument.

  - initDefaultProperties
```
protected final void initDefaultProperties()
```
    Description copied from class: Dialect
    
    Set appropriate default values for configuration properties.
    This default implementation sets "hibernate.jdbc.batch_size", "hibernate.jdbc.lob.non_contextual_creation", and "hibernate.jdbc.use_get_generated_keys" to defaults determined by calling Dialect.getDefaultStatementBatchSize(), Dialect.getDefaultNonContextualLobCreation(), and Dialect.getDefaultUseGetGeneratedKeys().
    An implementation may set additional configuration properties, but this is discouraged.

```
public void registerColumnTypes(TypeContributions typeContributions,

```
    Description copied from class: Dialect
    
    Register ANSI-standard column types using the length limits defined by Dialect.getMaxVarcharLength(), Dialect.getMaxNVarcharLength(), and Dialect.getMaxVarbinaryLength().
    This method is always called when a Dialect is instantiated.
    
    Overrides:
    
    registerColumnTypes in class Dialect
  - columnType
```
public 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.
    Overrides:

```
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])
    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.

```
    Description copied from class: Dialect
    
    Do the given JDBC type codes, as defined in Types represent essentially the same type in this dialect of SQL?
    The default implementation treats NUMERIC and DECIMAL as the same type, and FLOAT, REAL, and DOUBLE as essentially the same type, since the ANSI SQL specification fails to meaningfully distinguish them.
    The default implementation also treats VARCHAR, NVARCHAR, LONGVARCHAR, and LONGNVARCHAR as the same type, and BINARY and LONGVARBINARY as the same type, since Hibernate doesn't really differentiate these types.
    On the other hand, integral types are not treated as equivalent, instead, Dialect.isCompatibleIntegralType(int, int) is responsible for determining if the types are compatible.

    Description copied from class: Dialect
    
    If this dialect supports specifying lock timeouts, are those timeouts rendered into the SQL string as parameters? The implication is that Hibernate will need to bind the timeout value as a parameter in the PreparedStatement. If true, the parameter position is always handled as the last parameter; if the dialect specifies the lock timeout elsewhere in the SQL statement then the timeout value should be directly rendered into the statement and this method should return false.
    
    Overrides:
    
    isLockTimeoutParameterized in class Dialect
    
    Returns:
    
    True if the lock timeout is rendered into the SQL string as a parameter; false otherwise.

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

    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.

```
    Description copied from class: Dialect
    The IdentifierHelper indicated by this dialect for handling identifier conversions. Returning null is allowed and indicates that Hibernate should fall back to building a "standard" helper. In the fallback path, any changes made to the IdentifierHelperBuilder during this call will still be incorporated into the built IdentifierHelper.
    The incoming builder will have the following set:
    
    IdentifierHelperBuilder.isGloballyQuoteIdentifiers()
    
    IdentifierHelperBuilder.getUnquotedCaseStrategy() - initialized to UPPER
    
    IdentifierHelperBuilder.getQuotedCaseStrategy() - initialized to MIXED
    
    By default, Hibernate will do the following:
    
    Call IdentifierHelperBuilder.applyIdentifierCasing(DatabaseMetaData)
    Call IdentifierHelperBuilder.applyReservedWords(DatabaseMetaData)
    Applies AnsiSqlKeywords.sql2003() as reserved words
    
    Applies the {#link #sqlKeywords} collected here as reserved words
    
    Applies the Dialect's NameQualifierSupport, if it defines one
    Overrides:

    Returns:
    
    The IdentifierHelper instance to use, or null to indicate Hibernate should use its fallback path
    
    Throws:
    
    SQLException - Accessing the DatabaseMetaData can throw it. Just rethrow and Hibernate will handle it.
