SQLServer2005Dialect

public SQLServer2005Dialect()

Constructs a SQLServer2005Dialect

Method Detail

buildLimitHandler

public LimitHandler buildLimitHandler(String sql,
                             RowSelection selection)

Description copied from class: Dialect

Build delegate managing LIMIT clause.

Overrides:

buildLimitHandler in class Dialect

Parameters:

sql - SQL query.

selection - Selection criteria. null in case of unlimited number of rows.

Returns:

LIMIT clause delegate.

appendLockHint

public String appendLockHint(LockOptions lockOptions,
                    String tableName)

Description copied from class: Dialect

Some dialects support an alternative means to SELECT FOR UPDATE, whereby a "lock hint" is appends to the table name in the from clause.

contributed by Helge Schulz

Overrides:

appendLockHint in class SQLServerDialect

Parameters:

lockOptions - The lock options to apply

tableName - The name of the table to which to apply the lock hint.

Returns:

The table with any required lock hints.

buildSQLExceptionConversionDelegate

public SQLExceptionConversionDelegate buildSQLExceptionConversionDelegate()

Description copied from class: Dialect

Build an instance of a SQLExceptionConversionDelegate for interpreting dialect-specific error or SQLState codes.

When Dialect.buildSQLExceptionConverter() returns null, the default SQLExceptionConverter is used to interpret SQLState and error codes. If this method is overridden to return a non-null value, the default SQLExceptionConverter will use the returned SQLExceptionConversionDelegate in addition to the following standard delegates:

1. a "static" delegate based on the JDBC 4 defined SQLException hierarchy;
2. a delegate that interprets SQLState codes for either X/Open or SQL-2003 codes, depending on java.sql.DatabaseMetaData#getSQLStateType

It is strongly recommended that specific Dialect implementations override this method, since interpretation of a SQL error is much more accurate when based on the a vendor-specific ErrorCode rather than the SQLState.

Specific Dialects may override to return whatever is most appropriate for that vendor.

Overrides:

buildSQLExceptionConversionDelegate in class Dialect

Returns:

The SQLExceptionConversionDelegate for this dialect

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

Returns:

The "add column" fragment.

getNullColumnString

public String getNullColumnString()

Description copied from class: Dialect

The keyword used to specify a nullable column.

Overrides:

getNullColumnString in class Dialect

Returns:

String

qualifyIndexName

public boolean qualifyIndexName()

Description copied from class: Dialect

Do we need to qualify index names with the schema name?

Overrides:

qualifyIndexName in class Dialect

Returns:

boolean

getForUpdateString

public String getForUpdateString()

Description copied from class: Dialect

Get the string to append to SELECT statements to acquire locks for this dialect.

Overrides:

getForUpdateString in class Dialect

Returns:

The appropriate FOR UPDATE clause string.

supportsIdentityColumns

public boolean supportsIdentityColumns()

Description copied from class: Dialect

Does this dialect support identity column key generation?

Overrides:

supportsIdentityColumns in class Dialect

Returns:

True if IDENTITY columns are supported; false otherwise.

getIdentitySelectString

public String getIdentitySelectString()

Description copied from class: Dialect

Get the select command to use to retrieve the last generated IDENTITY value.

Overrides:

getIdentitySelectString in class Dialect

Returns:

The appropriate select command

getIdentityColumnString

public String getIdentityColumnString()

Description copied from class: Dialect

The syntax used during DDL to define a column as being an IDENTITY.

Overrides:

getIdentityColumnString in class Dialect

Returns:

The appropriate DDL fragment.

supportsInsertSelectIdentity

public boolean supportsInsertSelectIdentity()

Description copied from class: Dialect

Does the dialect support some form of inserting and selecting the generated IDENTITY value all in the same statement.

Overrides:

supportsInsertSelectIdentity in class Dialect

Returns:

True if the dialect supports selecting the just generated IDENTITY in the insert statement.

applyLocksToSql

public String applyLocksToSql(String sql,
                     LockOptions aliasedLockOptions,
                     Map<String,String[]> keyColumnNames)

Description copied from class: Dialect

Modifies the given SQL by applying the appropriate updates for the specified lock modes and key columns.

The behavior here is that of an ANSI SQL SELECT FOR UPDATE. This method is really intended to allow dialects which do not support SELECT FOR UPDATE to achieve this in their own fashion.

Overrides:

applyLocksToSql in class Dialect

Parameters:

sql - the SQL string to modify

aliasedLockOptions - lock options indexed by aliased table names.

keyColumnNames - a map of key columns indexed by aliased table names.

Returns:

the modified SQL string.

registerResultSetOutParameter

public int registerResultSetOutParameter(CallableStatement statement,
                                int col)
                                  throws SQLException

Description copied from class: Dialect

Registers a parameter (either OUT, or the new REF_CURSOR param type available in Java 8) capable of returning ResultSet *by position*. Pre-Java 8, registering such ResultSet-returning parameters varied greatly across database and drivers; hence its inclusion as part of the Dialect contract.

Overrides:

registerResultSetOutParameter in class Dialect

Parameters:

statement - The callable statement.

col - The bind position at which to register the output param.

Returns:

The number of (contiguous) bind positions used.

Throws:

SQLException - Indicates problems registering the param.

getResultSet

public ResultSet getResultSet(CallableStatement ps)
                       throws SQLException

Description copied from class: Dialect

Given a callable statement previously processed by Dialect.registerResultSetOutParameter(java.sql.CallableStatement, int), extract the ResultSet from the OUT parameter.

Overrides:

getResultSet in class Dialect

Parameters:

ps - The callable statement.

Returns:

The extracted result set.

Throws:

SQLException - Indicates problems extracting the result set.

Description copied from class: Dialect

Does this dialect support a way to retrieve the database's current timestamp value?

Overrides:

supportsCurrentTimestampSelection in class Dialect

Returns:

True if the current timestamp can be retrieved; false otherwise.

isCurrentTimestampSelectStringCallable

public boolean isCurrentTimestampSelectStringCallable()

Description copied from class: Dialect
