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 classDialect
- Returns:
- True if constraints must be dropped prior to dropping the table; false otherwise.
-
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.
-
getAddForeignKeyConstraintString
public java.lang.String getAddForeignKeyConstraintString(java.lang.String constraintName, java.lang.String[] foreignKey, java.lang.String referencedTable, java.lang.String[] primaryKey, boolean referencesPrimaryKey)
Description copied from class:Dialect
The syntax used to add a foreign key constraint to a table.- Overrides:
getAddForeignKeyConstraintString
in classDialect
- Parameters:
constraintName
- The FK constraint name.foreignKey
- The names of the columns comprising the FKreferencedTable
- The table referenced by the FKprimaryKey
- The explicit columns in the referencedTable referenced by this FK.referencesPrimaryKey
- if false, constraint should be explicit about which column names the constraint refers to- Returns:
- the "add FK" fragment
-
getAddForeignKeyConstraintString
public java.lang.String getAddForeignKeyConstraintString(java.lang.String constraintName, java.lang.String foreignKeyDefinition)
- Overrides:
getAddForeignKeyConstraintString
in classDialect
-
getAddPrimaryKeyConstraintString
public java.lang.String getAddPrimaryKeyConstraintString(java.lang.String constraintName)
Description copied from class:Dialect
The syntax used to add a primary key constraint to a table.- Overrides:
getAddPrimaryKeyConstraintString
in classDialect
- Parameters:
constraintName
- The name of the PK constraint.- Returns:
- The "add PK" 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
-
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
-
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.
-
createCaseFragment
public CaseFragment createCaseFragment()
Description copied from class:Dialect
Create aCaseFragment
strategy responsible for handling this dialect's variations in how CASE statements are handled.- Overrides:
createCaseFragment
in classDialect
- Returns:
- This dialect's
CaseFragment
strategy.
