构造器详细资料

PostgreSQL82Dialect

public PostgreSQL82Dialect()

方法详细资料

supportsIfExistsBeforeTableName

public boolean supportsIfExistsBeforeTableName()

从类复制的说明: Dialect

For dropping a table, can the phrase "if exists" be applied before the table name?

NOTE : Only one or the other (or neither) of this and Dialect.supportsIfExistsAfterTableName() should return true

覆盖:

supportsIfExistsBeforeTableName 在类中 Dialect

返回:

true if the "if exists" can be applied before the table name

contributeTypes

public void contributeTypes(TypeContributions typeContributions,
                            ServiceRegistry serviceRegistry)

从类复制的说明: Dialect

Allows the Dialect to contribute additional types

覆盖:

contributeTypes 在类中 Dialect

参数:

typeContributions - Callback to contribute the types

serviceRegistry - The service registry

getDefaultMultiTableBulkIdStrategy

public MultiTableBulkIdStrategy getDefaultMultiTableBulkIdStrategy()

覆盖:

getDefaultMultiTableBulkIdStrategy 在类中 PostgreSQL81Dialect

getDropSequenceString

public String getDropSequenceString(String sequenceName)

从类复制的说明: Dialect

Typically dialects which support sequences can drop a sequence with a single command. This is convenience form of Dialect.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 override Dialect.getDropSequenceStrings(java.lang.String).

覆盖:

getDropSequenceString 在类中 PostgreSQL81Dialect

参数:

sequenceName - The name of the sequence

返回:

The sequence drop commands

supportsValuesList

public boolean supportsValuesList()

从类复制的说明: Dialect

Does this dialect/database support VALUES list (e.g. VALUES (1), (2), (3) )

覆盖:

supportsValuesList 在类中 Dialect

返回:

true if VALUES list are supported

supportsRowValueConstructorSyntaxInInList

public boolean supportsRowValueConstructorSyntaxInInList()

从类复制的说明: Dialect

If the dialect supports row values, does it offer such support in IN lists as well?

For example, "... where (FIRST_NAME, LAST_NAME) IN ( (?, ?), (?, ?) ) ..."

覆盖:

supportsRowValueConstructorSyntaxInInList 在类中 Dialect

返回:

True if this SQL dialect is known to support "row value constructor" syntax in the IN list; false otherwise.
