Method Detail

renderOrderByElement
public java.lang.String renderOrderByElement(java.lang.String expression, java.lang.String collation, java.lang.String order, NullPrecedence nulls)
Description copied from class:Dialect
Renders an ordering fragment- Overrides:
renderOrderByElement
in classDialect
- Parameters:
expression
- The SQL order expression. In case of@OrderBy
annotation user receives property placeholder (e.g. attribute name enclosed in '{' and '}' signs).collation
- Collation string in formatcollate IDENTIFIER
, ornull
if expression has not been explicitly specified.order
- Order direction. Possible values:asc
,desc
, ornull
if expression has not been explicitly specified.nulls
- Nulls precedence. Default value:NullPrecedence.NONE
.- Returns:
- Renders single element of
ORDER BY
clause.
-
supportsValuesList
public boolean supportsValuesList()
Description copied from class:Dialect
Does this dialect/database support VALUES list (e.g. VALUES (1), (2), (3) )- Overrides:
supportsValuesList
in classDialect
- Returns:
true
if VALUES list are supported
-
getAddColumnString
public java.lang.String getAddColumnString()
Description copied from class:Dialect
The syntax used to add a column to a table (optional).- Overrides:
getAddColumnString
in classDialect
- Returns:
- The "add column" fragment.
-
getNullColumnString
public java.lang.String getNullColumnString()
Description copied from class:Dialect
The keyword used to specify a nullable column.- Overrides:
getNullColumnString
in classDialect
- Returns:
- String
-
qualifyIndexName
public boolean qualifyIndexName()
Description copied from class:Dialect
Do we need to qualify index names with the schema name?- Overrides:
qualifyIndexName
in classDialect
- Returns:
- boolean
-
getForUpdateString
public java.lang.String getForUpdateString()
Description copied from class:Dialect
Get the string to append to SELECT statements to acquire locks for this dialect.- Overrides:
getForUpdateString
in classDialect
- Returns:
- The appropriate FOR UPDATE clause string.
-
applyLocksToSql
public java.lang.String applyLocksToSql(java.lang.String sql, LockOptions aliasedLockOptions, java.util.Map<java.lang.String,java.lang.String[]> keyColumnNames)
Description copied from class:Dialect
Modifies the given SQL by applying the appropriate updates for the specified lock modes and key columns. The behavior here is that of an ANSI SQL SELECT FOR UPDATE. This method is really intended to allow dialects which do not support SELECT FOR UPDATE to achieve this in their own fashion.- Overrides:
applyLocksToSql
in classDialect
- Parameters:
sql
- the SQL string to modifyaliasedLockOptions
- lock options indexed by aliased table names.keyColumnNames
- a map of key columns indexed by aliased table names.- Returns:
- the modified SQL string.
-

Description copied from class:Dialect
Registers a parameter (either OUT, or the new REF_CURSOR param type available in Java 8) capable of returningResultSet
*by position*. Pre-Java 8, registering such ResultSet-returning parameters varied greatly across database and drivers; hence its inclusion as part of the Dialect contract.- Overrides:
registerResultSetOutParameter
in classDialect
- Parameters:

- The callable statement.col
- The bind position at which to register the output param.- Returns:
- The number of (contiguous) bind positions used.
- Throws:
