构造器详细资料

MySQL5Dialect

public MySQL5Dialect()

方法详细资料

registerVarcharTypes

protected void registerVarcharTypes()

覆盖:

registerVarcharTypes 在类中 MySQLDialect

supportsColumnCheck

public boolean supportsColumnCheck()

从类复制的说明: Dialect

Does this dialect support column-level check constraints?

覆盖:

supportsColumnCheck 在类中 Dialect

返回:

True if column-level CHECK constraints are supported; false otherwise.

getViolatedConstraintNameExtracter

public ViolatedConstraintNameExtracter getViolatedConstraintNameExtracter()

指定者:

getViolatedConstraintNameExtracter 在接口中 ConversionContext

覆盖:

getViolatedConstraintNameExtracter 在类中 Dialect

getEngineKeyword

protected String getEngineKeyword()

覆盖:

getEngineKeyword 在类中 MySQLDialect

getQueryHintString

public String getQueryHintString(String query,
                                 String hints)

从类复制的说明: Dialect

Apply a hint to the query. The entire query is provided, allowing the Dialect full control over the placement and syntax of the hint. By default, ignore the hint and simply return the query.

覆盖:

getQueryHintString 在类中 Dialect

参数:

query - The query to which to apply the hint.

hints - The hints to apply

返回:

The modified SQL

supportsUnionAll

public boolean supportsUnionAll()

从类复制的说明: Dialect

Does this dialect support UNION ALL, which is generally a faster variant of UNION?

覆盖:

supportsUnionAll 在类中 Dialect

返回:

True if UNION ALL is supported; false otherwise.
