tdbc::mapSqlState(n) Tcl Database Connectivity tdbc::mapSqlState(n)______________________________________________________________________________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 exam‐
ple, FEATURE_NOT_SUPPORTED, DATA_EXCEPTION or INVALID_CURSOR_STATE).
The TDBC specification requires database drivers to return a descrip‐
tion of an error in the error code when an error occurs. The descrip‐
tion is a string that has at least four elements: "TDBC errorClass sql‐
state 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.
