Method Detail

dropConstraints

public boolean dropConstraints()

Description copied from class: Dialect

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

Overrides:

dropConstraints in class Dialect

Returns:

boolean

getAddColumnString

public String getAddColumnString()

Description copied from class: Dialect

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

Overrides:

getAddColumnString in class Dialect

getAddForeignKeyConstraintString

public String getAddForeignKeyConstraintString(String constraintName,
                                               String[] foreignKey,
                                               String referencedTable,
                                               String[] primaryKey,
                                               boolean referencesPrimaryKey)

Description copied from class: Dialect

The syntax used to add a foreign key constraint to a table.

Overrides:

getAddForeignKeyConstraintString in class Dialect

Parameters:

referencesPrimaryKey - if false, constraint should be explicit about which column names the constraint refers to

Returns:

String

getAddPrimaryKeyConstraintString

public String getAddPrimaryKeyConstraintString(String constraintName)

Description copied from class: Dialect

The syntax used to add a primary key constraint to a table.

Overrides:

getAddPrimaryKeyConstraintString in class Dialect

Returns:

String

getNullColumnString

public String getNullColumnString()

Description copied from class: Dialect

The keyword used to specify a nullable column.

Overrides:

getNullColumnString in class Dialect

Returns:

String

getSequenceNextValString

public String getSequenceNextValString(String sequenceName)

Description copied from class: Dialect

Generate the appropriate select statement to to retreive the next value of a sequence, if sequences are supported.

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 String getSelectSequenceNextValString(String sequenceName)

Description copied from class: Dialect

Generate the select expression fragment that will retreive the next value of a sequence, if sequences are supported.

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

Overrides:

getSelectSequenceNextValString in class Dialect

Parameters:

sequenceName - the name of the sequence

Returns:

String

getCreateSequenceString

public String getCreateSequenceString(String sequenceName)

Description copied from class: Dialect

The syntax used to create a sequence, if sequences are supported.

Overrides:

getCreateSequenceString in class Dialect

Parameters:

sequenceName - the name of the sequence

Returns:

String

getDropSequenceString

public String getDropSequenceString(String sequenceName)

Description copied from class: Dialect

The syntax used to drop a sequence, if sequences are supported.

Overrides:

getDropSequenceString in class Dialect

Parameters:

sequenceName - the name of the sequence

Returns:

String

getQuerySequencesString

public String getQuerySequencesString()

Description copied from class: Dialect

A query used to find all sequences

Overrides:

getQuerySequencesString in class Dialect

createOuterJoinFragment

public JoinFragment createOuterJoinFragment()

Description copied from class: Dialect

Create an OuterJoinGenerator for this dialect.

Overrides:

createOuterJoinFragment in class Dialect

Returns:

Description copied from class: Dialect

Does this dialect support sequences?

Overrides:

supportsSequences in class Dialect

Returns:

boolean

createCaseFragment

public CaseFragment createCaseFragment()

Description copied from class: Dialect

Create a CaseFragment for this dialect.

Overrides:

createCaseFragment in class Dialect

Returns:

OuterJoinGenerator

supportsTemporaryTables

public boolean supportsTemporaryTables()

Overrides:

supportsTemporaryTables in class Dialect

getCreateTemporaryTablePostfix

public String getCreateTemporaryTablePostfix()

Overrides:

getCreateTemporaryTablePostfix in class Dialect

generateTemporaryTableName

public String generateTemporaryTableName(String baseTableName)

Overrides:

generateTemporaryTableName in class Dialect
