  - columnType
```
protected String columnType(int sqlTypeCode)
```
    Description copied from class: Dialect
    
    The 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.

    columnType in class Dialect
    
    Parameters:
    
    sqlTypeCode - a SQL type code
    
    Returns:

  - initializeFunctionRegistry
```
public void initializeFunctionRegistry(QueryEngine queryEngine)
```
    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
    
    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])
    
    log10(arg)
    sign(arg)
    sin(arg)
    cos(arg)
    tan(arg)
    asin(arg)
    acos(arg)
    atan(arg)
    atan2(arg0, arg1)
    round(arg0, arg1)
    least(arg0, arg1, ...)
    greatest(arg0, 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
    
    Does the dialect support propagating changes to LOB values back to the database? Talking about mutating the internal value of the locator as opposed to supplying a new locator instance...
    For BLOBs, the internal value might be changed by: Blob.setBinaryStream(long), Blob.setBytes(long, byte[]), Blob.setBytes(long, byte[], int, int), or Blob.truncate(long).
    For CLOBs, the internal value might be changed by: Clob.setAsciiStream(long), Clob.setCharacterStream(long), Clob.setString(long, String), Clob.setString(long, String, int, int), or Clob.truncate(long).
    NOTE : I do not know the correct answer currently for databases which (1) are not part of the cruise control process or (2) do not Dialect.supportsExpectedLobUsagePattern().
    
    Overrides:
    
    supportsLobValueChangePropagation in class Dialect
    
    Returns:
    
    True if the changes are propagated back to the database; false otherwise.

    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 Dialect's NameQualifierSupport, if it defines one
    Overrides:
    
    buildIdentifierHelper in class Dialect
    
    Parameters:

    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.
