                               throws SQLException
```
    Retrieves a description of a table's optimal set of columns that uniquely identifies a row. They are ordered by SCOPE.
    Each column description has the following columns:
    1. SCOPE short => actual scope of result
      
      bestRowTemporary - very temporary, while using row
      bestRowTransaction - valid for remainder of current transaction
      bestRowSession - valid for remainder of current session
    2. COLUMN_NAME String => column name
    3. DATA_TYPE int => SQL data type from java.sql.Types
    4. TYPE_NAME String => Data source dependent type name, for a UDT the type name is fully qualified
    5. COLUMN_SIZE int => precision
    6. BUFFER_LENGTH int => not used
    7. DECIMAL_DIGITS short => scale - Null is returned for data types where DECIMAL_DIGITS is not applicable.
    8. PSEUDO_COLUMN short => is this a pseudo column like an Oracle ROWID
      
      bestRowUnknown - may or may not be pseudo column
      bestRowNotPseudo - is NOT a pseudo column
      bestRowPseudo - is a pseudo column
    The COLUMN_SIZE 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.
    Specified by:
    
    getBestRowIdentifier in interface DatabaseMetaData
    
    Parameters:
    
    catalog - a catalog name; must match the catalog name as it is stored in the database; "" retrieves those without a catalog; null means that the catalog name should not be used to narrow the search
    
    schema - ignored in SingleStore
    
    table - a table name; must match the table name as it is stored in the database
    
    scope - the scope of interest; use same values as SCOPE
    
    nullable - include columns that are nullable.
    
    Returns:
    
    ResultSet - each row is a column description
    
    Throws:
    
    SQLException - if a database access error occurs

                           throws SQLException
```
    Retrieves a description of the pseudo or hidden columns available in a given table within the specified catalog and schema. Pseudo or hidden columns may not always be stored within a table and are not visible in a ResultSet unless they are specified in the query's outermost SELECT list. Pseudo or hidden columns may not necessarily be able to be modified. If there are no pseudo or hidden columns, an empty ResultSet is returned.
    Only column descriptions matching the catalog, schema, table and column name criteria are returned. They are ordered by TABLE_CAT,TABLE_SCHEM, TABLE_NAME and COLUMN_NAME.
    Each column description has the following columns:
    1. TABLE_CAT String => table catalog (may be null)
    2. TABLE_SCHEM String => table schema (may be null)
    3. TABLE_NAME String => table name
    4. COLUMN_NAME String => column name
    5. DATA_TYPE int => SQL type from java.sql.Types
    6. COLUMN_SIZE int => column size.
    7. DECIMAL_DIGITS int => the number of fractional digits. Null is returned for data types where DECIMAL_DIGITS is not applicable.
    8. NUM_PREC_RADIX int => Radix (typically either 10 or 2)
    9. COLUMN_USAGE String => The allowed usage for the column. The value returned will correspond to the enum name returned by PseudoColumnUsage.name()
    10. REMARKS String => comment describing column (may be null)
    11. CHAR_OCTET_LENGTH int => for char types the maximum number of bytes in the column
    12. 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
    The COLUMN_SIZE column specifies the 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.

public ResultSet getTypeInfo()
```
    Retrieves a description of all the data types supported by this database. They are ordered by DATA_TYPE and then by how closely the data type maps to the corresponding JDBC SQL type.
    If the database supports SQL distinct types, then getTypeInfo() will return a single row with a TYPE_NAME of DISTINCT and a DATA_TYPE of Types.DISTINCT. If the database supports SQL structured types, then getTypeInfo() will return a single row with a TYPE_NAME of STRUCT and a DATA_TYPE of Types.STRUCT.
    If SQL distinct or structured types are supported, then information on the individual types may be obtained from the getUDTs() method.
    Each type description has the following columns:
    1. TYPE_NAME String => Type name
    2. DATA_TYPE int => SQL data type from java.sql.Types
    3. PRECISION int => maximum precision
    4. LITERAL_PREFIX String => prefix used to quote a literal (may be null)
    5. LITERAL_SUFFIX String => suffix used to quote a literal (may be null)
    6. CREATE_PARAMS String => parameters used in creating the type (may be null)
    7. NULLABLE short => can you use NULL for this type.
      
      typeNoNulls - does not allow NULL values
      typeNullable - allows NULL values
      typeNullableUnknown - nullability unknown
    8. CASE_SENSITIVE boolean=> is it case sensitive.
    9. SEARCHABLE short => can you use "WHERE" based on this type:
      
      typePredNone - No support
      typePredChar - Only supported with WHERE .. LIKE
      typePredBasic - Supported except for WHERE .. LIKE
      typeSearchable - Supported for all WHERE ..
    10. UNSIGNED_ATTRIBUTE boolean => is it unsigned.
    11. FIXED_PREC_SCALE boolean => can it be a money value.
    12. AUTO_INCREMENT boolean => can it be used for an auto-increment value.
    13. LOCAL_TYPE_NAME String => localized version of type name (may be null)
    14. MINIMUM_SCALE short => minimum scale supported
    15. MAXIMUM_SCALE short => maximum scale supported
    16. SQL_DATA_TYPE int => unused
    17. SQL_DATETIME_SUB int => unused
    18. NUM_PREC_RADIX int => usually 2 or 10
    The PRECISION column represents the maximum column size that the server supports for the given datatype. 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.
