    7. FKTABLE_NAME String => foreign key table name
    8. FKCOLUMN_NAME String => foreign key column name
    9. KEY_SEQ short => sequence number within a foreign key( a value of 1 represents the first column of the foreign key, a value of 2 would represent the second column within the foreign key).
    10. UPDATE_RULE short => What happens to a foreign key when the primary key is updated:
      
      importedNoAction - do not allow update of primary key if it has been imported
      importedKeyCascade - change imported key to agree with primary key update
      importedKeySetNull - change imported key to NULL if its primary key has been updated
      importedKeySetDefault - change imported key to default values if its primary key has been updated
      importedKeyRestrict - same as importedKeyNoAction (for ODBC 2.x compatibility)
    11. DELETE_RULE short => What happens to the foreign key when primary is deleted.
      
      importedKeyNoAction - do not allow delete of primary key if it has been imported
      importedKeyCascade - delete rows that import a deleted key
      importedKeySetNull - change imported key to NULL if its primary key has been deleted
      importedKeyRestrict - same as importedKeyNoAction (for ODBC 2.x compatibility)
      importedKeySetDefault - change imported key to default if its primary key has been deleted
    12. FK_NAME String => foreign key name (may be null)
    13. PK_NAME String => primary key name (may be null)
    14. DEFERRABILITY short => can the evaluation of foreign key constraints be deferred until commit

```
    Generate part of the information schema query that restricts catalog names In the driver, catalogs is the equivalent to MariaDB schemas.
    
    Parameters:
    
    columnName - - column name in the information schema table
    
    catalog - - catalog name. This driver does not (always) follow JDBC standard for following special values, due to ConnectorJ compatibility 1. empty string ("") - matches current catalog (i.e database). JDBC standard says only tables without catalog should be returned - such tables do not exist in MariaDB. If there is no current catalog, then empty string matches any catalog. 2. null - if nullCatalogMeansCurrent=true (which is the default), then the handling is the same as for "" . i.e return current catalog.JDBC-conforming way would be to match any catalog with null parameter. This can be switched with nullCatalogMeansCurrent=false in the connection URL.
    
    Returns:
    
    part of SQL query ,that restricts search for the catalog.

```
    Retrieves a description of the given catalog's stored procedure parameter and result columns.
    Only descriptions matching the schema, procedure and parameter name criteria are returned. They are ordered by PROCEDURE_CAT, PROCEDURE_SCHEM, PROCEDURE_NAME and SPECIFIC_NAME. Within this, the return value, if any, is first. Next are the parameter descriptions in call order. The column descriptions follow in column number order.
    
    Each row in the ResultSet is a parameter description or column description with the following fields:
    1. PROCEDURE_CAT String => procedure catalog (may be null)
    2. PROCEDURE_SCHEM String => procedure schema (may be null)
    3. PROCEDURE_NAME String => procedure name
    4. COLUMN_NAME String => column/parameter name
    5. COLUMN_TYPE Short => kind of column/parameter:
      
      procedureColumnUnknown - nobody knows
      procedureColumnIn - IN parameter
      procedureColumnInOut - INOUT parameter
      procedureColumnOut - OUT parameter
      procedureColumnReturn - procedure return value
      procedureColumnResult - result column in ResultSet
    6. DATA_TYPE int => SQL type from java.sql.Types
    7. TYPE_NAME String => SQL type name, for a UDT type the type name is fully qualified
    8. PRECISION int => precision
    9. LENGTH int => length in bytes of data
    10. SCALE short => scale - null is returned for data types where SCALE is not applicable.
    11. RADIX short => radix
    12. NULLABLE short => can it contain NULL.
      
      procedureNoNulls - does not allow NULL values
      procedureNullable - allows NULL values
      procedureNullableUnknown - nullability unknown
    13. REMARKS String => comment describing parameter/column
    14. COLUMN_DEF String => default value for the column, which should be interpreted as a string when the value is enclosed in single quotes (may be null)
      
      The string NULL (not enclosed in quotes) - if NULL was specified as the default value
      TRUNCATE (not enclosed in quotes) - if the specified default value cannot be represented without truncation
      NULL - if a default value was not specified
    15. SQL_DATA_TYPE int => reserved for future use
    16. SQL_DATETIME_SUB int => reserved for future use
    17. CHAR_OCTET_LENGTH int => the maximum length of binary and character based columns. For any other datatype the returned value is a NULL
    18. ORDINAL_POSITION int => the ordinal position, starting from 1, for the input and output parameters for a procedure. A value of 0 is returned if this row describes the procedure's return value. For result set columns, it is the ordinal position of the column in the result set starting from 1. If there are multiple result sets, the column ordinal positions are implementation defined.
    19. IS_NULLABLE String => ISO rules are used to determine the nullability for a column.
      
      YES --- if the column can include NULLs
      NO --- if the column cannot include NULLs
      empty string --- if the nullability for the column is unknown
    20. SPECIFIC_NAME String => the name which uniquely identifies this procedure within its schema.
    Note: Some databases may not return the column descriptions for a procedure.
    
    The PRECISION column represents the specified column size for the given column. For numeric data, this is the maximum precision. For character data, this is the length in characters. For datetime datatypes, this is the length in characters of the String representation (assuming the maximum allowed precision of the fractional seconds component). For binary data, this is the length in bytes. For the ROWID datatype, this is the length in bytes. Null is returned for data types where the column size is not applicable.

    Retrieves a description of the given catalog's system or user function parameters and return type.
    Only descriptions matching the schema, function and parameter name criteria are returned. They are ordered by FUNCTION_CAT, FUNCTION_SCHEM, FUNCTION_NAME and SPECIFIC_ NAME. Within this, the return value, if any, is first. Next are the parameter descriptions in call order. The column descriptions follow in column number order.
    
    Each row in the ResultSet is a parameter description, column description or return type description with the following fields:
    1. FUNCTION_CAT String => function catalog (may be null)
    2. FUNCTION_SCHEM String => function schema (may be null)
    3. FUNCTION_NAME String => function name. This is the name used to invoke the function
    4. COLUMN_NAME String => column/parameter name
    5. COLUMN_TYPE Short => kind of column/parameter:
      
      functionColumnUnknown - nobody knows
      functionColumnIn - IN parameter
      functionColumnInOut - INOUT parameter
      functionColumnOut - OUT parameter
      functionColumnReturn - function return value
      functionColumnResult - Indicates that the parameter or column is a column in the ResultSet
    6. DATA_TYPE int => SQL type from java.sql.Types
    7. TYPE_NAME String => SQL type name, for a UDT type the type name is fully qualified
    8. PRECISION int => precision
    9. LENGTH int => length in bytes of data
    10. SCALE short => scale - null is returned for data types where SCALE is not applicable.
    11. RADIX short => radix
    12. NULLABLE short => can it contain NULL.
      
      functionNoNulls - does not allow NULL values
      functionNullable - allows NULL values
      functionNullableUnknown - nullability unknown
    13. REMARKS String => comment describing column/parameter
    14. CHAR_OCTET_LENGTH int => the maximum length of binary and character based parameters or columns. For any other datatype the returned value is a NULL
    15. ORDINAL_POSITION int => the ordinal position, starting from 1, for the input and output parameters. A value of 0 is returned if this row describes the function's return value. For result set columns, it is the ordinal position of the column in the result set starting from 1.
    16. IS_NULLABLE String => ISO rules are used to determine the nullability for a parameter or column.
      
      YES --- if the parameter or column can include NULLs
      NO --- if the parameter or column cannot include NULLs
      empty string --- if the nullability for the parameter or column is unknown
    17. SPECIFIC_NAME String => the name which uniquely identifies this function within its schema. This is a user specified, or DBMS generated, name that may be different then the FUNCTION_NAME for example with overload functions
    The PRECISION column represents the specified column size for the given parameter or column. For numeric data, this is the maximum precision. For character data, this is the length in characters. For datetime datatypes, this is the length in characters of the String representation (assuming the maximum allowed precision of the fractional seconds component). For binary data, this is the length in bytes. For the ROWID datatype, this is the length in bytes. Null is returned for data types where the column size is not applicable.

```
    Retrieves a description of the user-defined type (UDT) hierarchies defined in a particular schema in this database. Only the immediate super type/ sub type relationship is modeled. Only supertype information for UDTs matching the catalog, schema, and type name is returned. The type name parameter may be a fully-qualified name. When the UDT name supplied is a fully-qualified name, the catalog and schemaPattern parameters are ignored. If a UDT does not have a direct super type, it is not listed here. A row of the ResultSet object returned by this method describes the designated UDT and a direct supertype. A row has the following columns:
    1. TYPE_CAT String => the UDT's catalog (may be null)
    2. TYPE_SCHEM String => UDT's schema (may be null)
    3. TYPE_NAME String => type name of the UDT
    4. SUPERTYPE_CAT String => the direct super type's catalog (may be null)
    5. SUPERTYPE_SCHEM String => the direct super type's schema (may be null)
    6. SUPERTYPE_NAME String => the direct super type's name
    Note: If the driver does not support type hierarchies, an empty result set is returned.

```
    Retrieves a description of the table hierarchies defined in a particular schema in this database.
    Only supertable information for tables matching the catalog, schema and table name are returned. The table name parameter may be a fully-qualified name, in which case, the catalog and schemaPattern parameters are ignored. If a table does not have a super table, it is not listed here. Supertables have to be defined in the same catalog and schema as the sub tables. Therefore, the type description does not need to include this information for the supertable.
    
    Each type description has the following columns:
    1. TABLE_CAT String => the type's catalog (may be null)
    2. TABLE_SCHEM String => type's schema (may be null)
    3. TABLE_NAME String => type name
    4. SUPERTABLE_NAME String => the direct super type's name
    Note: If the driver does not support type hierarchies, an empty result set is returned.
