public enum SQLDialect extends Enum<SQLDialect>
jOOQ supports a variety of dialects, which are grouped into dialect families.
For instance, the SQL Server dialect family POSTGRES

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.

public final SQLDialect family()
This returns the dialect itself, if it has no "parent family". E.g.
SQLSERVER == SQLSERVER2012.family();
SQLSERVER == SQLSERVER2008.family();
SQLSERVER == SQLSERVER.family();
public final SQLDialect predecessor()
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.
public final boolean precedes(SQLDialect other)
This returns:
true
if this dialect is the same as the other dialecttrue
if this dialect precedes the other dialect via any
number of calls to predecessor()
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 {
