Constructs a new MSSQLDBAccess Object.

Method Detail

insertDatabaseSpecific

public Object[] insertDatabaseSpecific(String pWritebackTable,
                                       String pInsertStatement,
                                       ServerMetaData pServerMetaData,
                                       Object[] pNewDataRow,
                                       String pDummyColumn)
                                throws DataSourceException

Returns the newly inserted row from an Database specific insert statement.
Database specific derivations of DBAcces need to implement it database specific.

Overrides:

insertDatabaseSpecific in class DBAccess

Parameters:

pWritebackTable - the table to use for the insert

pInsertStatement - the SQL Statement to use for the insert

pServerMetaData - the meta data to use.

pNewDataRow - the new row (Object[]) with the values to insert

pDummyColumn - null, if all writeable columns are null, but for a correct INSERT it have to be minimum one column to use in the syntax.

Returns:

the newly inserted row from an Oracle Database.

Throws:

DataSourceException - if an Exception occur during insert to the storage

translateDefaultValue

protected Object translateDefaultValue(String pColumnName,
                                       int pDataType,
                                       String pDefaultValue)
                                throws Exception

Translates a default value from a column to the datatype object.

Overrides:

translateDefaultValue in class DBAccess

Parameters:

pColumnName - the column name to translate

pDataType - the datatype of the column

pDefaultValue - the original default value from the database

Returns:

the default value with the datatype of the column or null if the default value is not valid

Throws:

Exception - if the type translation causes an error or the datatype is not supported

getAllowedValues

public Hashtable<String,Object[]> getAllowedValues(String pCatalog,
                                                   String pSchema,
                                                   String pTable)
                                            throws DataSourceException

Gets the allowed values from a specific table. The allowed values are defined through check constraints or other table related restrictions.

Overrides:

getAllowedValues in class DBAccess

Parameters:

pCatalog - the catalog name

pSchema - the schema name

pTable - the table to check

Returns:

a Hashtable with a column name as key and the allowed values as array of Objects or null if there are no allowed values

Throws:

DataSourceException - if the database access throws an exception

isAutoQuote

public boolean isAutoQuote(String pName)

Description copied from class: DBAccess

It returns true if this name should be automated quoted. e.g. in Oracle default all isUppercase(), so if the name has one loweCase character, then AutoQuote is true to quote this name.

Overrides:

isAutoQuote in class DBAccess

Parameters:

pName - the name to quote.

Returns:

true if this name should be automated quoted.

setUsername

public void setUsername(String pUsername)

Description copied from class: DBAccess

Sets the user name to connect with.

Overrides:

setUsername in class DBAccess

Parameters:

pUsername - the user name

getColumnMetaData

public DBAccess.ColumnMetaDataInfo getColumnMetaData(String pFromClause,
                                                     String[] pQueryColumns,
                                                     String pBeforeQueryColumns,
                                                     String pWhereClause,

                                                     String[] pWritebackColumns)
                                              throws DataSourceException

Description copied from class: DBAccess

Returns the meta data information for the specified query, and configures all columns with defaults.

Overrides:

getColumnMetaData in class DBAccess

Parameters:
