Dialect

protected Dialect(String schema)

Method Details

getSchema

protected final String getSchema()

quoteName

public String quoteName(String name)

Quotes a database name. This prevents the name from being interpreted as a SQL keyword. This is usually done by enclosing the name with some (database specific) quotation characters. The default implementation uses double quotes as specified by ANSI SQL.

supportsCheckConstraints

public boolean supportsCheckConstraints()

supportsSemicolon

public boolean supportsSemicolon()

adjustExistingCheckConstraintCondition

protected String adjustExistingCheckConstraintCondition(String s)

getColumnType

protected abstract String getColumnType(int dataType,
 ResultSet resultSet)
                                 throws SQLException

Throws:

SQLException

verify

protected abstract void verify(Schema schema)

verifyTablesByMetaData

protected static final void verifyTablesByMetaData(Schema schema)

verifyColumnsByMetaData

protected final void verifyColumnsByMetaData(Schema schema,
 String tableSchema)

Parameters:

tableSchema - null means any schema is allowed

verifyForeignKeyConstraints

protected static final void verifyForeignKeyConstraints(String sql,
 Schema schema)

verifyUniqueConstraints

protected static final void verifyUniqueConstraints(String sql,
 Schema schema)

verifySequences

protected static final void verifySequences(String sql,
 Schema schema)

notifyExistentTable

protected static final void notifyExistentTable(Schema schema,
 String tableName)

notifyExistentColumn

protected static final Column notifyExistentColumn(Table table,
 String columnName,
 String existingType)

notifyExistentCheck

protected static final void notifyExistentCheck(Table table,
 String constraintName,
 String condition)

notifyExistentPrimaryKey

protected static final void notifyExistentPrimaryKey(Table table,
 String constraintName)

notifyExistentUnique

protected static final void notifyExistentUnique(Table table,
 String constraintName,
 String condition)

notifyExists

protected static final void notifyExists(Sequence sequence,
 Sequence.Type existingType)

getBooleanStrict

protected static final boolean getBooleanStrict(ResultSet resultSet,
 int columnIndex,
 String trueValue,
 String falseValue)
                                         throws SQLException

Throws:

SQLException

getTableStrict

protected static final Table getTableStrict(Schema schema,
 ResultSet resultSet,
 int columnIndex)
                                     throws SQLException

Throws:

SQLException

querySQL

protected final void querySQL(Schema schema,
 String statement,
 Dialect.ResultSetHandler resultSetHandler)

getCatalog

protected static final String getCatalog(Schema schema)

appendTableCreateStatement

protected void appendTableCreateStatement(StringBuilder bf)

Parameters:

bf - used in subclasses

needsTargetColumnName

protected boolean needsTargetColumnName()

appendForeignKeyCreateStatement

protected void appendForeignKeyCreateStatement(StringBuilder bf)

Parameters:

bf - used in subclasses

renameTable

public String renameTable(String tableName,
 String newTableName)

renameColumn

public abstract String renameColumn(String tableName,
 String oldColumnName,
 String newColumnName,
 String columnType)

createColumn

public abstract String createColumn(String tableName,
 String columnName,
 String columnType)

modifyColumn

public abstract String modifyColumn(String tableName,
 String columnName,
 String newColumnType)

dropPrimaryKeyConstraint

protected void dropPrimaryKeyConstraint(StringBuilder bf,
 String tableName,
 String constraintName)

dropForeignKeyConstraint

protected void dropForeignKeyConstraint(StringBuilder bf,
 String tableName,
 String constraintName)

dropUniqueConstraint

protected void dropUniqueConstraint(StringBuilder bf,
 String tableName,
 String constraintName)

createSequence

protected abstract void createSequence(StringBuilder bf,
 String sequenceName,
 Sequence.Type type,
 long start)

dropSequence

 String sequenceName)

deleteSchema

@Deprecated
public final void deleteSchema(Schema schema)

Deprecated.

Use Model.deleteSchema() instead.

The default implementation just drops and re-creates the schema. Subclasses are encouraged to provide a more efficient implementation.
