MySqlDialect

public MySqlDialect()

方法详细资料

getRowConverter

public org.apache.flink.connector.jdbc.core.database.dialect.JdbcDialectConverter getRowConverter(org.apache.flink.table.types.logical.RowType rowType)

getLimitClause

public String getLimitClause(long limit)

defaultDriverName

public Optional<String> defaultDriverName()

quoteIdentifier

public String quoteIdentifier(String identifier)

getUpsertStatement

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

Mysql upsert query use DUPLICATE KEY UPDATE.

NOTE: It requires Mysql's primary key to be consistent with pkFields.

We don't use REPLACE INTO, if there are other fields, we can keep their previous values.
