    max(arg) - aggregate function
    min(arg) - aggregate function
    sum(arg) - aggregate function

    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])
    
    sign(arg)
    sin(arg)
    cos(arg)
    tan(arg)
    asin(arg)
    acos(arg)
    atan(arg)
    atan2(arg0, arg1)

    least(arg0, arg1, ...)
    greatest(arg0, arg1, ...)
    
    format(datetime as pattern)
    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)

    Description copied from class: Dialect
    Does this dialect support referencing the table being mutated in a subquery. The "table being mutated" is the table referenced in an UPDATE or a DELETE query. And so can that table then be referenced in a subquery of said UPDATE/DELETE query.

    delete from TABLE_A where ID not in ( select ID from TABLE_A )
    
    update TABLE_A set NON_ID = 'something' where ID in ( select ID from TABLE_A)

  - buildSQLExceptionConversionDelegate
```
public SQLExceptionConversionDelegate buildSQLExceptionConversionDelegate()
```
    Description copied from class: Dialect
    Build an instance of a 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 JDBC 4 defined SQLException hierarchy;
    
    a delegate that interprets SQLState codes for either X/Open or SQL-2003 codes, depending on java.sql.DatabaseMetaData#getSQLStateType
    
    It is strongly recommended that specific Dialect implementations override this method, since interpretation of a SQL error is much more accurate when based on the vendor-specific ErrorCode rather than the SQLState.
    Specific Dialects may override to return whatever is most appropriate for that vendor.
    Overrides:
    
    buildSQLExceptionConversionDelegate in class Dialect
    
    Returns:
    
    The SQLExceptionConversionDelegate for this dialect

```
    Description copied from class: Dialect
    Build the IdentifierHelper indicated by this Dialect for handling identifier conversions. Returning null is allowed and indicates that Hibernate should fallback 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:
    
    buildIdentifierHelper in class Dialect
    
    Parameters:
    
    builder - A semi-configured IdentifierHelper builder.
    
    dbMetaData - Access to the metadata returned from the driver if needed and if available. WARNING: may be null
    
    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 re-throw and Hibernate will handle.
