IdentityColumnSupportImpl

public IdentityColumnSupportImpl()

方法详细资料

supportsIdentityColumns

public boolean supportsIdentityColumns()

从接口复制的说明: IdentityColumnSupport

Does this dialect support identity column key generation?

指定者:

supportsIdentityColumns 在接口中 IdentityColumnSupport

返回:

True if IDENTITY columns are supported; false otherwise.

supportsInsertSelectIdentity

public boolean supportsInsertSelectIdentity()

从接口复制的说明: IdentityColumnSupport

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

指定者:

supportsInsertSelectIdentity 在接口中 IdentityColumnSupport

返回:

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

hasDataTypeInIdentityColumn

public boolean hasDataTypeInIdentityColumn()

从接口复制的说明: IdentityColumnSupport

Whether this dialect have an Identity clause added to the data type or a completely separate identity data type

指定者:

hasDataTypeInIdentityColumn 在接口中 IdentityColumnSupport

返回:

boolean

appendIdentitySelectToInsert

public String appendIdentitySelectToInsert(String insertString)

从接口复制的说明: IdentityColumnSupport

Provided we IdentityColumnSupport.supportsInsertSelectIdentity(), then attach the "select identity" clause to the insert statement.

Note, if IdentityColumnSupport.supportsInsertSelectIdentity() == false then the insert-string should be returned without modification.

指定者:

appendIdentitySelectToInsert 在接口中 IdentityColumnSupport

参数:

insertString - The insert command

返回:

The insert command with any necessary identity select clause attached.

getIdentitySelectString

public String getIdentitySelectString(String table,
                                      String column,
                                      int type)
                               throws MappingException

从接口复制的说明: IdentityColumnSupport

Get the select command to use to retrieve the last generated IDENTITY value for a particular table

指定者:

getIdentitySelectString 在接口中 IdentityColumnSupport

参数:

table - The table into which the insert was done

column - The PK column.

type - The Types type code.

返回:

The appropriate select command

抛出:

MappingException - If IDENTITY generation is not supported.

getIdentityColumnString

public String getIdentityColumnString(int type)
                               throws MappingException

从接口复制的说明: IdentityColumnSupport

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

指定者:

getIdentityColumnString 在接口中 IdentityColumnSupport

参数:

type - The Types type code.

返回:

The appropriate DDL fragment.

抛出:

MappingException - If IDENTITY generation is not supported.

getIdentityInsertString

public String getIdentityInsertString()

从接口复制的说明: IdentityColumnSupport

The keyword used to insert a generated value into an identity column (or null). Need if the dialect does not support inserts that specify no column values.

指定者:

getIdentityInsertString 在接口中 IdentityColumnSupport

返回:

The appropriate keyword.

buildGetGeneratedKeysDelegate

public GetGeneratedKeysDelegate buildGetGeneratedKeysDelegate(PostInsertIdentityPersister persister,
                                                              Dialect dialect)

从接口复制的说明: IdentityColumnSupport

The Delegate for dealing with IDENTITY columns using JDBC3 getGeneratedKeys

指定者:

buildGetGeneratedKeysDelegate 在接口中 IdentityColumnSupport

参数:

persister - The persister

dialect - The dialect against which to generate the delegate

返回:

the dialect specific GetGeneratedKeys delegate
