NAME

       tdbc::mapSqlState - Map SQLSTATE to error class

SYNOPSIS

       package require tdbc 1.0

       tdbc::mapSqlState sqlstate
_________________________________________________________________________________________________

DESCRIPTION

       The  tdbc::mapSqlState  command  accepts  a string that is expected to be a five-character
       'SQL state' as returned from a SQL database when an error occurs. It  examines  the  first
       two  characters of the string, and returns an error class as a human- and machine-readable
       name (for example, FEATURE_NOT_SUPPORTED, DATA_EXCEPTION or INVALID_CURSOR_STATE).

       The TDBC specification requires database drivers to return a description of  an  error  in
       the  error  code  when an error occurs. The description is a string that has at least four
       elements: "TDBC errorClass sqlstate driverName details...". The tdbc::mapSqlState  command
       gives  a convenient way for a TDBC driver to generate the errorClass element given the SQL
       state returned from a database.
