构造器详细资料

SqliteDialect

public SqliteDialect()

方法详细资料

dialectName

public String dialectName()

从接口复制的说明: JdbcDialect

Get the name of jdbc dialect.

指定者:

dialectName 在接口中 JdbcDialect

返回:

the dialect name.

getRowConverter

public JdbcRowConverter getRowConverter()

从接口复制的说明: JdbcDialect

Get converter that convert jdbc object to seatunnel internal object.

指定者:

getRowConverter 在接口中 JdbcDialect

返回:

a row converter for the database

getJdbcDialectTypeMapper

public JdbcDialectTypeMapper getJdbcDialectTypeMapper()

从接口复制的说明: JdbcDialect

get jdbc meta-information type to seatunnel data type mapper.

指定者:

getJdbcDialectTypeMapper 在接口中 JdbcDialect

返回:

a type mapper for the database

quoteIdentifier

public String quoteIdentifier(String identifier)

从接口复制的说明: JdbcDialect

Quotes the identifier for table name or field name

指定者:

quoteIdentifier 在接口中 JdbcDialect

getUpsertStatement

public Optional<String> getUpsertStatement(String database,
                                           String tableName,
                                           String[] fieldNames,
                                           String[] uniqueKeyFields)

从接口复制的说明: JdbcDialect

Constructs the dialects upsert statement if supported; such as MySQL's DUPLICATE KEY UPDATE, or PostgreSQL's ON CONFLICT... DO UPDATE SET...

If supported, the returned string will be used as a PreparedStatement. Fields in the statement must be in the same order as the fieldNames parameter.

If the dialect does not support native upsert statements, the writer will fallback to SELECT ROW Exists + UPDATE/INSERT which may have poor performance.

指定者:

getUpsertStatement 在接口中 JdbcDialect

返回:

the dialects UPSERT statement or Optional.empty().
