Method Detail

getAddColumnString

public java.lang.String getAddColumnString()

Deprecated.

Description copied from class: Dialect

The syntax used to add a column to a table (optional).

Overrides:

getAddColumnString in class Dialect

Returns:

The "add column" fragment.

getSequenceNextValString

public java.lang.String getSequenceNextValString(java.lang.String sequenceName)

Deprecated.

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 class Dialect

Parameters:

sequenceName - the name of the sequence

Returns:

String The "nextval" select string.

getSelectSequenceNextValString

public java.lang.String getSelectSequenceNextValString(java.lang.String sequenceName)

Deprecated.

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 from Dialect.getSequenceNextValString(String) in that this should return an expression usable within another statement.

Overrides:

getSelectSequenceNextValString in class Dialect

Parameters:

sequenceName - the name of the sequence

Returns:

The "nextval" fragment.

getCreateSequenceString

public java.lang.String getCreateSequenceString(java.lang.String sequenceName)

Deprecated.

Description copied from class: Dialect

Typically dialects which support sequences can create a sequence with a single command. This is convenience form of Dialect.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 override Dialect.getCreateSequenceStrings(java.lang.String).

Overrides:

getCreateSequenceString in class Dialect

Parameters:

sequenceName - The name of the sequence

Returns:

The sequence creation command

getDropSequenceString

public java.lang.String getDropSequenceString(java.lang.String sequenceName)

Deprecated.

Description copied from class: Dialect

Typically dialects which support sequences can drop a sequence with a single command. This is convenience form of Dialect.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 override Dialect.getDropSequenceStrings(java.lang.String).

Overrides:

getDropSequenceString in class Dialect

Parameters:

sequenceName - The name of the sequence

Returns:

The sequence drop commands

getCascadeConstraintsString

public java.lang.String getCascadeConstraintsString()

Deprecated.

Description copied from class: Dialect

Completely optional cascading drop clause

Overrides:

getCascadeConstraintsString in class Dialect

Returns:

String

dropConstraints

public boolean dropConstraints()

Deprecated.

Description copied from class: Dialect

Do we need to drop constraints before dropping tables in this dialect?

Overrides:

dropConstraints in class Dialect

Returns:

True if constraints must be dropped prior to dropping the table; false otherwise.

getForUpdateNowaitString

public java.lang.String getForUpdateNowaitString()

Deprecated.

Description copied from class: Dialect

Retrieves the FOR UPDATE NOWAIT syntax specific to this dialect.

Overrides:

getForUpdateNowaitString in class Dialect

Returns:

The appropriate FOR UPDATE NOWAIT clause string.

supportsSequences

public boolean supportsSequences()

Deprecated.

Description copied from class: Dialect

Does this dialect support sequences?

Overrides:

supportsSequences in class Dialect

Returns:

True if sequences supported; false otherwise.

supportsPooledSequences

public boolean supportsPooledSequences()

Deprecated.

Description copied from class: Dialect

Does this dialect support "pooled" sequences. Not aware of a better name for this. Essentially can we specify the initial and increment values?

Overrides:

supportsPooledSequences in class Dialect

Returns:

True if such "pooled" sequences are supported; false otherwise.

See Also:

Dialect.getCreateSequenceStrings(String, int, int), Dialect.getCreateSequenceString(String, int, int)

supportsLimit

public boolean supportsLimit()

Deprecated.

Description copied from class: Dialect

Does this dialect support some form of limiting query results via a SQL clause?

Overrides:

supportsLimit in class Dialect

Returns:

True if this dialect supports some form of LIMIT.

getLimitString

public java.lang.String getLimitString(java.lang.String sql,
                              boolean hasOffset)

Deprecated.

Description copied from class: Dialect

Apply s limit clause to the query.

Typically dialects utilize variable 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 and Dialect.getLimitString(String, int, int).

Overrides:

getLimitString in class Dialect

Parameters:

sql - The query to which to apply the limit.

hasOffset - Is the query requesting an offset?

Returns:

the modified SQL

getForUpdateString

public java.lang.String getForUpdateString(java.lang.String aliases)

Deprecated.

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 class Dialect

Parameters:

aliases - The columns to be write locked.

Returns:

The appropriate FOR UPDATE OF column_list clause string.

getForUpdateNowaitString

public java.lang.String getForUpdateNowaitString(java.lang.String aliases)

Deprecated.

Description copied from class: Dialect

Get the FOR UPDATE OF column_list NOWAIT fragment appropriate for this dialect given the aliases of the columns to be write locked.

Overrides:

getForUpdateNowaitString in class Dialect

Parameters:

aliases - The columns to be write locked.

Returns:

The appropriate FOR UPDATE colunm_list NOWAIT clause string.

bindLimitParametersInReverseOrder

public boolean bindLimitParametersInReverseOrder()

Deprecated.

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 class Dialect

Returns:

true if the correct order is limit, offset

useMaxForLimit

public boolean useMaxForLimit()

Deprecated.

Description copied from class: Dialect

Does the LIMIT clause take a "maximum" row number instead of a total number of returned rows?

This is easiest understood via an example. Consider you have a table with 20 rows, but you only want to retrieve rows number 11 through 20. Generally, a limit with offset would say that the offset = 11 and the limit = 10 (we only want 10 rows at a time); this is specifying the total number of returned rows. Some dialects require that we instead specify offset = 11 and limit = 20, where 20 is the "last" row we want relative to offset (i.e. total number of rows = 20 - 11 = 9)

So essentially, is limit relative from offset? Or is limit absolute?

Overrides:

useMaxForLimit in class Dialect

Returns:

True if limit is relative from offset; false otherwise.

forUpdateOfColumns

public boolean forUpdateOfColumns()

Deprecated.

Description copied from class: Dialect

Is FOR UPDATE OF syntax supported?

Overrides:

forUpdateOfColumns in class Dialect

Returns:

True if the database supports FOR UPDATE OF syntax; false otherwise.

getQuerySequencesString

public java.lang.String getQuerySequencesString()

Deprecated.

Description copied from class: Dialect

Get the select command used retrieve the names of all sequences.

Overrides:

getQuerySequencesString in class Dialect

Returns:

The select command; or null if sequences are not supported.

Overrides:

Returns:

The appropriate command.

getViolatedConstraintNameExtracter

public ViolatedConstraintNameExtracter getViolatedConstraintNameExtracter()

Deprecated.

Overrides:

getViolatedConstraintNameExtracter in class Dialect

                                  throws java.sql.SQLException

Deprecated.
