All Implemented Interfaces:

InformationExtractor

public class MySqlReactiveInformationExtractorImpl
extends AbstractReactiveInformationSchemaBasedExtractorImpl

An implementation of AbstractReactiveInformationSchemaBasedExtractorImpl specifically for MySQL that obtains metadata from MySQL's non-standard information_schema tables.

MySQL's schema is actually a catalog. MySQL's implementation of DatabaseMetaData automatically changes catalog arguments to refer to schema columns instead. Unfortunately, MySQL's information_schema stores catalog names in a schema name column. This class works around that idiosyncrasy.

Method Details

dataTypeCode

protected int dataTypeCode(String typeName)

Description copied from class: AbstractReactiveInformationSchemaBasedExtractorImpl

Return a JDBC Type code for the given type name

Overrides:

dataTypeCode in class AbstractReactiveInformationSchemaBasedExtractorImpl

getDatabaseCatalogColumnName

protected String getDatabaseCatalogColumnName(String catalogColumnName,
 String schemaColumnName)

Description copied from class: AbstractReactiveInformationSchemaBasedExtractorImpl

Given a catalog column name and a schema column name in an information_schema table/view, this method returns the column used for storing the catalog name, or , if there is no valid column containing the catalog name.

MySQL, for example, uses the schema name column in the information_schema to store the catalog name. (@see MySqlReactiveInformationExtractorImpl)

Overrides:

getDatabaseCatalogColumnName in class AbstractReactiveInformationSchemaBasedExtractorImpl

Parameters:

catalogColumnName - - the catalog column name

schemaColumnName - - the schema column name

Returns:

the column used for storing the catalog name, or if there is no valid column containing the catalog name.

getDatabaseSchemaColumnName

protected String getDatabaseSchemaColumnName(String catalogColumnName,
 String schemaColumnName)

Description copied from class: AbstractReactiveInformationSchemaBasedExtractorImpl

Given a catalog column name and a schema column name in an information_schema table/view, this method returns the column used for storing the schema name, or , if there is no valid column containing the schema name.

MySQL, for example, does not have a valid column in the information_schema to store the schema name. (@see MySqlReactiveInformationExtractorImpl)

Overrides:

getDatabaseSchemaColumnName in class AbstractReactiveInformationSchemaBasedExtractorImpl

Parameters:

catalogColumnName - - the catalog column name

schemaColumnName - - the schema column name

Returns:

the column used for storing the schema name, or if there is no valid column containing the schema name.
