```
Dialects and dialect families as supported by jOOQ.
The commercial jOOQ distributions support a variety of dialects, which are grouped into dialect families. For instance, the SQL Server dialect family POSTGRES is specialised by its dialects
- #POSTGRES_9_3
- #POSTGRES_9_4

  - SQL99
```
@Deprecated
public static final SQLDialect SQL99
```
    Deprecated. - [#3844] - 3.6.0 - DEFAULT will replace this pseudo-dialect.
    
    The standard SQL dialect family.
  - DEFAULT
```
public static final SQLDialect DEFAULT
```
    The default SQL dialect.
    This dialect is chosen in the absence of a more explicit dialect. It is not intended to be used with any actual database as it may combined dialect-specific things from various dialects.
  - CUBRID
```
public static final SQLDialect CUBRID
```
    The CUBRID dialect family.
  - DERBY
```
public static final SQLDialect DERBY
```
    The Apache Derby dialect family.
  - FIREBIRD
```
public static final SQLDialect FIREBIRD
```
    The Firebird dialect family.
    This family behaves like the versioned dialect #FIREBIRD_3_0.
  - H2
```
public static final SQLDialect H2
```
    The H2 dialect family.
  - HSQLDB
```
public static final SQLDialect HSQLDB
```
    The Hypersonic dialect family.
  - MARIADB
```
public static final SQLDialect MARIADB
```
    The MariaDB dialect family.
  - MYSQL
```
public static final SQLDialect MYSQL
```
    The MySQL dialect family.
    This family behaves like the versioned dialect #MYSQL_8_0.
  - POSTGRES
```
public static final SQLDialect POSTGRES
```
    The PostgreSQL dialect family.
    This family behaves like the versioned dialect #POSTGRES_11.
    While this family (and its dialects) have been observed to work to some extent on Amazon RedShift as well, we strongly suggest you use the official #REDSHIFT support, instead.
  - SQLITE
```
public static final SQLDialect SQLITE
```
    The SQLite dialect family.
    This family behaves like the versioned dialect #SQLITE_3_28.
- Method Detail
  - values
```
public static SQLDialect[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
```
for (SQLDialect c : SQLDialect.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static SQLDialect valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
  - commercial
```
public final boolean commercial()
```
    Whether this dialect is supported with the jOOQ commercial license only.
  - supported
```
public final boolean supported()
```
    Whether this dialect is supported by jOOQ as an output dialect.
    Unsupported, non-output dialects include:
    - DEFAULT: A hypothetical dialect used for QueryPart.toString() calls of unattached query parts.
    - SQL99: A legacy version of DEFAULT.
    - #POSTGRESPLUS: A not yet supported dialect.
  - family
```
public final SQLDialect family()
```
    The dialect family.
    This returns the dialect itself, if it has no "parent family". E.g.
```
 SQLSERVER == SQLSERVER2012.family();
 SQLSERVER == SQLSERVER2008.family();
 SQLSERVER == SQLSERVER.family();
 
```
  - isFamily
```
public final boolean isFamily()
```
    Whether this dialect is a family().
  - predecessor
```
public final SQLDialect predecessor()
```
    The predecessor dialect.
    If this is a dialect version (e.g. #POSTGRES_9_4) within a family (e.g. POSTGRES), then the predecessor will point to the historically previous dialect version (e.g. #POSTGRES_9_3) within the same family, or to the dialect itself if there was no predecessor explicitly supported by jOOQ.
  - precedes
```
public final boolean precedes(SQLDialect other)
```
    Whether this dialect precedes an other dialect from the same family.
    This returns:
    - true if this dialect is the same as the other dialect
    - true if this dialect precedes the other dialect via any number of calls to predecessor()
    The above also implies that:
    - false if the two dialects do not belong to the same family
    This is useful to see if some feature is supported by "at least" a given dialect version. Example:
```
 // Do this block only if the chosen dialect supports PostgreSQL 9.4+ features
 if (POSTGRES_9_4.precedes(dialect)) {
 }

 // Do this block only if the chosen dialect supports PostgreSQL 9.3+ features
 else if (POSTGRES_9_3.precedes(dialect)) {
 }

 // Fall back to pre-PostgreSQL 9.3 behaviour
 else {
 }
 
```
  - supports
```
public final boolean supports(SQLDialect other)
```
    Check whether this dialect supports another one.
    This is:
    - false if dialects don't belong to the same family
    - true if either dialect isFamily()
    - true if other dialect precedes this dialect
    The other argument dialect is typically referenced from a Support annotation, whereas this dialect is the user dialect.
  - supports
```
public final boolean supports(Collection<SQLDialect> other)
```
    Check whether this dialect supports any dialect from the argument collection.
  - getName
```
public final String getName()
```
    The name of this dialect as it appears in related class names.
  - getNameLC
```
public final String getNameLC()
```
    The name of this dialect as it appears in related package names.
  - getNameUC
```
public final String getNameUC()
```
    The name of this dialect as it appears in related enum values.
  - families
```
public static final SQLDialect[] families()
```
    Get a list of all family() values.
  - thirdParty
```
public final SQLDialect.ThirdParty thirdParty()
```
    Get access to third party representations of this SQLDialect.
