```
    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

    - 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])
    - sign(arg)
    - sin(arg)
    - cos(arg)
    - tan(arg)

    - 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)

  - buildSQLExceptionConversionDelegate
```
public SQLExceptionConversionDelegate buildSQLExceptionConversionDelegate()
```
    Description copied from class: Dialect
    Build an instance of a SQLExceptionConversionDelegate for interpreting dialect-specific error or SQLState codes.
    When Dialect.buildSQLExceptionConverter() returns null, the default SQLExceptionConverter is used to interpret SQLState and error 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 JDBC 4 defined SQLException hierarchy;
    2. 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

  - supportsExpectedLobUsagePattern
```
public boolean supportsExpectedLobUsagePattern()
```
    Description copied from class: Dialect
    
    Expected LOB usage pattern is such that I can perform an insert via prepared statement with a parameter binding for a LOB value without crazy casting to JDBC driver implementation-specific classes...
    Part of the trickiness here is the fact that this is largely driver dependent. For example, Oracle (which is notoriously bad with LOB support in their drivers historically) actually does a pretty good job with LOB support as of the 10.2.x versions of their drivers...
    
    Overrides:
    
    supportsExpectedLobUsagePattern in class Dialect
    
    Returns:
    
    True if normal LOB usage patterns can be used with this driver; false if driver-specific hookiness needs to be applied.

```
public boolean supportsUnboundedLobLocatorMaterialization()
```
    Description copied from class: Dialect
    
    Is it supported to materialize a LOB locator outside the transaction in which it was created?
    Again, part of the trickiness here is the fact that this is largely driver dependent.
    NOTE: all database I have tested which Dialect.supportsExpectedLobUsagePattern() also support the ability to materialize a LOB outside the owning transaction...
    
    Overrides:
    
    supportsUnboundedLobLocatorMaterialization in class Dialect
    
    Returns:
    
    True if unbounded materialization is supported; false otherwise.

    Overrides:
    
    dropConstraints in class Dialect
    
    Returns:
    
    True if constraints must be dropped prior to dropping the table; false otherwise.

    Is this dialect known to support what ANSI-SQL terms "row value constructor" syntax; sometimes called tuple syntax.
    Basically, does it support syntax like "... where (FIRST_NAME, LAST_NAME) = ('Steve', 'Ebersole') ...".
    
    Overrides:
    
    supportsRowValueConstructorSyntax in class Dialect
    
    Returns:
    
    True if this SQL dialect is known to support "row value constructor" syntax; false otherwise.
  - supportsRowValueConstructorSyntaxInInList
```
public boolean supportsRowValueConstructorSyntaxInInList()
```
    Description copied from class: Dialect

  - getMaxAliasLength
```
public int getMaxAliasLength()
```
    Description copied from class: Dialect
    
    What is the maximum length Hibernate can use for generated aliases?
    The maximum here should account for the fact that Hibernate often needs to append "uniqueing" information to the end of generated aliases. That "uniqueing" information will be added to the end of a identifier generated to the length specified here; so be sure to leave some room (generally speaking 5 positions will suffice).
    
    Overrides:
    
    getMaxAliasLength in class Dialect
    
    Returns:
    
    The maximum length.

    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.
