Method Detail
-
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.
-
getSequenceNextValString
public java.lang.String getSequenceNextValString(java.lang.String sequenceName)
Description copied from class:Dialect
Generate the appropriate select statement to to retrieve the next value of a sequence. This should be a "stand alone" select statement.- Overrides:
getSequenceNextValString
in classDialect
- Parameters:
sequenceName
- the name of the sequence- Returns:
- String The "nextval" select string.
-
getSelectSequenceNextValString
public java.lang.String getSelectSequenceNextValString(java.lang.String sequenceName)
Description copied from class:Dialect
Generate the select expression fragment that will retrieve the next value of a sequence as part of another (typically DML) statement. This differs fromDialect.getSequenceNextValString(String)
in that this should return an expression usable within another statement.- Overrides:
getSelectSequenceNextValString
in classDialect
- Parameters:
sequenceName
- the name of the sequence- Returns:
- The "nextval" fragment.
-
getCreateSequenceString
public java.lang.String getCreateSequenceString(java.lang.String sequenceName)
Description copied from class:Dialect
Typically dialects which support sequences can create a sequence with a single command. This is convenience form ofDialect.getCreateSequenceStrings(java.lang.String)
to help facilitate that. Dialects which support sequences and can create a sequence in a single command need *only* override this method. Dialects which support sequences but require multiple commands to create a sequence should instead overrideDialect.getCreateSequenceStrings(java.lang.String)
.- Overrides:
getCreateSequenceString
in classDialect
- Parameters:
sequenceName
- The name of the sequence- Returns:
- The sequence creation command
-
getDropSequenceString
public java.lang.String getDropSequenceString(java.lang.String sequenceName)
Description copied from class:Dialect
Typically dialects which support sequences can drop a sequence with a single command. This is convenience form ofDialect.getDropSequenceStrings(java.lang.String)
to help facilitate that. Dialects which support sequences and can drop a sequence in a single command need *only* override this method. Dialects which support sequences but require multiple commands to drop a sequence should instead overrideDialect.getDropSequenceStrings(java.lang.String)
.- Overrides:
getDropSequenceString
in classDialect
- Parameters:
sequenceName
- The name of the sequence- Returns:
- The sequence drop commands
-
getQuerySequencesString
public java.lang.String getQuerySequencesString()
Description copied from class:Dialect
Get the select command used retrieve the names of all sequences.- Overrides:
getQuerySequencesString
in classDialect
- Returns:
- The select command; or null if sequences are not supported.
- See Also:
SchemaUpdate
-
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.
-
getForUpdateString
public java.lang.String getForUpdateString(java.lang.String aliases)
Description copied from class:Dialect
Get the FOR UPDATE OF column_list fragment appropriate for this dialect given the aliases of the columns to be write locked.- Overrides:
getForUpdateString
in classDialect
- Parameters:
aliases
- The columns to be write locked.- Returns:
- The appropriate FOR UPDATE OF column_list clause string.
-
supportsSequences
public boolean supportsSequences()
Description copied from class:Dialect
Does this dialect support sequences?- Overrides:
supportsSequences
in classDialect
- Returns:
- True if sequences supported; false otherwise.
-
getLimitHandler
public LimitHandler getLimitHandler()
Description copied from class:Dialect
Returns the delegate managing LIMIT clause.- Overrides:
getLimitHandler
in classDialect
- Returns:
- LIMIT clause delegate.
-
supportsLimit
public boolean supportsLimit()
Description copied from class:Dialect
Does this dialect support some form of limiting query results via a SQL clause?- Overrides:
supportsLimit
in classDialect
- Returns:
- True if this dialect supports some form of LIMIT.
-
getLimitString
public java.lang.String getLimitString(java.lang.String sql, boolean hasOffset)
Description copied from class:Dialect
Apply s limit clause to the query. Typically dialects utilizevariable
limit clauses when they support limits. Thus, when building the select command we do not actually need to know the limit or the offest since we will just be using placeholders. Here we do still pass along whether or not an offset was specified so that dialects not supporting offsets can generate proper exceptions. In general, dialects will override one or the other of this method andDialect.getLimitString(String, int, int)
.- Overrides:
getLimitString
in classDialect
- Parameters:
sql
- The query to which to apply the limit.hasOffset
- Is the query requesting an offset?- Returns:
- the modified SQL
-
bindLimitParametersFirst
public boolean bindLimitParametersFirst()
Description copied from class:Dialect
Does the LIMIT clause come at the start of the SELECT statement, rather than at the end?- Overrides:
bindLimitParametersFirst
in classDialect
- Returns:
- true if limit parameters should come before other parameters
-
bindLimitParametersInReverseOrder
public boolean bindLimitParametersInReverseOrder()
Description copied from class:Dialect
ANSI SQL defines the LIMIT clause to be in the form LIMIT offset, limit. Does this dialect require us to bind the parameters in reverse order?- Overrides:
bindLimitParametersInReverseOrder
in classDialect
- Returns:
- true if the correct order is limit, offset
-
getCurrentTimestampSelectString
public java.lang.String getCurrentTimestampSelectString()
Description copied from class:Dialect
Retrieve the command used to retrieve the current timestamp from the database.- Overrides:
getCurrentTimestampSelectString
in classDialect
- Returns:
- The command.
-
isCurrentTimestampSelectStringCallable
public boolean isCurrentTimestampSelectStringCallable()
Description copied from class:Dialect
Should the value returned byDialect.getCurrentTimestampSelectString()
be treated as callable. Typically this indicates that JDBC escape syntax is being used...- Overrides:
isCurrentTimestampSelectStringCallable
in classDialect
- Returns:
- True if the
Dialect.getCurrentTimestampSelectString()
return is callable; false otherwise.
